What’s the Matter with Descartes?<br />
By Timothy Vance<br />
“...God, like one of our own architects, approached the task of constructing<br />
the universe with order and pattern, and laid out the indivitual parts accordingly,<br />
as if it were not art which imitated Nature, but God himself had looked<br />
to the mode of building Man who was to be.”<br />
Johannes Kepler<br />
Mysterium Cosmographicum
Editorial<br />
At the moment this issue of Δυναμις is being put to<br />
print, there is a vast, immediate battle being waged for the future<br />
of the human race. On the one side, Lyndon LaRouche is mobilizing<br />
a team of national governments to erect a new international<br />
credit system, based on the best aspects of the American System<br />
of Economics. On the other side, an old oligarchical empire, centered<br />
in London, England, is unleashing the terrorist hordes it has<br />
been fostering through the international drug trade for years, to<br />
preserve its power and create chaos, potentially leading to the assassination<br />
of America’s president elect.<br />
To think clearly in a time of crisis such as this, one needs<br />
to be creative.<br />
August of this year past marked an historic turning<br />
point in the development of the scientific capabilities of humanity.<br />
Concluding a month long seminar series on the conceptions<br />
associated with Carl Gauss’s discovery of the orbit of Ceres, the<br />
Gauss “Basement” team passed the baton to the next team, who<br />
was tasked with blazing the trail into Riemann’s conception of<br />
higher hypergeometries. Simultaneously, a selection of former<br />
Basement dwellers produced an hour long Δυναμις video, taking<br />
Harvard University, and the rest of so-called academia, to task,<br />
for graduating uneducated boobs (such as George W. Bush) into<br />
positions of influence in our society. This video, The Harvard<br />
Yard (http://www.larouchepac.com), presents a real history of<br />
Kepler’s discovery of our harmonic solar system, as opposed to<br />
the Newtonian witch-quackery of “action at a distance” heaped<br />
out in its place today.<br />
The new Riemann team has already made history, by<br />
making several new discoveries about Riemann’s early development.<br />
In looking back at Riemann’s own written draft manuscripts<br />
on Geistesmassen, or thought-objects, they found that<br />
several key sections had been kept out of the published version<br />
in his collected works, edited (selectively) by Heinrich Weber. In<br />
re-translating the entirety of Riemann’s writing on this subject,<br />
they put together an initial picture of how Riemann’s work on the<br />
mind informed his conceptions of related physical phenomena<br />
such as gravitation, light, heat, and magnetism, through to the<br />
end of his life.<br />
A crucial insight was made by the team leader, Sky<br />
Shields, who had begun investigating Wolfgang Köhler and his<br />
school of Gestalt Psychology. Köhler found that the mind does<br />
not assemble its ideas from small parts and sense impressions, but<br />
that all thoughts are derived from whole gestalts. In attempting<br />
to find a mapping between this activity of the mind and the human<br />
nervous system, he ran into a conceptual block which came<br />
from physics. Assuming that thoughts are just epiphenomena of<br />
mechanical or chemical (i.e. nonliving) processes in the brain,<br />
implicitly eliminates the possibility of a higher mental principle<br />
that can order lower thought phenomena. Köhler had thought that<br />
the most appropriate physical model, where a higher principle or-<br />
ders the lower, observed phenomena, was what Carl Gauss, and<br />
later Riemann, called potential. The 20th Century introduction<br />
and promotion of the science of little hard particles, called atomic<br />
science, had virtually replaced the study of potential.<br />
Köhler saw that the observed relationship between the<br />
mind and the senses can only exist in a universe composed of<br />
gestalts – which can, in cross section, be expressed as what we<br />
might call individual thoughts, much like a potential field expresses<br />
itself, in cross section, as the motion of the bodies in that<br />
field. This notion was in exactly the same spirit as Riemann, who<br />
declared that all of what we explain as “forces” are expressions<br />
of the motion of a space-filling matter, not a Newtonian war of<br />
nut-tugging.<br />
Nobody who thinks, really believes in the particles-acting-at-a-distance<br />
hoax, anyhow. It is merely a form of social control.<br />
To help break this control, the Riemann team has produced<br />
a video, called The Matter of Mind (http://www.larouchepac.<br />
com), laying out the argument that, only the science from Kepler<br />
through Gauss, Riemann, and Köhler is real – the other stuff is<br />
what makes slaves.<br />
During the transition to the Riemann team, one of the<br />
outgoing members of the Gauss team, Michael Kirsch, prepared<br />
a report about the conceptual history of elliptical functions, from<br />
Nicholas of Cusa up through Gauss and Riemann. His report<br />
forms the centerpiece of this issue of Δυναμις, and is supplemented<br />
by translations of Carl Gauss’s third proof of the Fundamental<br />
Theorem of Algebra and a letter he wrote to his student Bessel<br />
on the true nature of physical functions, and also a translation<br />
of Johann Bernoulli’s first lecture on the integral calculus. Also<br />
included is a report written by Lyndon LaRouche, to aid in clarifying<br />
a crucial issue in how humans generate discoveries. Last,<br />
Δυναμις has obtained an exclusive interview with none other<br />
than René Descartes.<br />
The reader should be reminded, that the reports contained<br />
inside Δυναμις represent the rebirth of true science, which<br />
has virtually died out over the past century. The true mission of<br />
a young person today, must be to become a true scientist (which<br />
also means learning how to perform classical choral counterpoint).<br />
The next real scientific breakthroughs must be made in<br />
this generation, and not wait for some distant point in the future.<br />
The survival of the human race depends on breakthroughs in our<br />
understanding of the universe, so don’t waste your time. Anybody<br />
can read a popular science magazine, but it was only a few<br />
driven individuals who went further than anybody else ever had.<br />

The Calling of Elliptical Functions<br />

The Calling of Elliptical Functions<br />
How a Lemniscate is Not Other than a Riemann Surface<br />
Michael Kirsch<br />
Hear now from those who sought to tame the principles<br />
of transcendental physical pathways, bringing into<br />
mankind’s understanding the principles which were<br />
uncertain.<br />
Gauss’s discovery of the characteristics of functions,<br />
related to those processes which Johann Bernoulli defined as elliptical,<br />
and Riemann’s later explicit reworking of his concept of<br />
an elliptical function, led to a new degree of conceptual freedom<br />
for mankind—an ability to understand that the reality of a process<br />
can be understood by the internal unseen characteristics of the<br />
process itself, rather than by any predicates.<br />
The importance of this realization, is that it defines the<br />
historical arc of investigating transcendental processes of nature,<br />
as a continous development of demonstrating the human mind’s<br />
ability to conceive of invisible principles in their own domain,<br />
without depending on false shadows and images. This is not to<br />
say that the invisible principles are now seen, sensed, or even understood<br />
directly, but rather, the principles are come to be known<br />
not in terms of what effects they produce, but how those effects<br />
are produced.<br />
The specific principle here goes far beyond the subject<br />
matter involved; it is as Kepler’s captive, the physical pathway<br />
of the Mars orbit, which, when brought into the understanding of<br />
the human mind, is applied to increase mankind’s power and effectiveness.<br />
Just as certain principles, when applied to society as<br />
a whole, have the effect of increasing the power of labor through<br />
technological advancement, this principle of understanding how<br />
processes can be known and conceptualized, is as important as it<br />
is extensive.<br />
This important realization defines a continuity through<br />
the foundation of modern science to its maturity. It leads one to<br />
understand something fundamental about the human mind, why<br />
it must be defended, and why civilization’s main object is the<br />
pursuit of its development.<br />
The Foundation of Modern Science<br />
Cardinal Nicolas of Cusa defined the method of investigating<br />
processes in his dialogue On Not-Other. The following<br />
reasoning from his dialogue serves to introduce his concept:<br />
What causes us to know, what most gives us knowledge<br />
of the world? Definition. How is definition known? The definition<br />
is expressed from the defining of a thing---definitions define<br />
all things. And if definition defines everything, does it not define<br />
itself? Then the definition defining everything is not other than<br />
the defined.<br />
What Cusa presents to the reader of On Not-other, is<br />
that principles of nature, such as light, or heat, define themselves.<br />
From this characteristic, principles do not have pieces from which<br />
they are made; they are indivisibles, units. The distinguishing<br />
character of men then becomes whether they, in investigating the<br />
effects of light, for example, keep their mind on the principle of<br />
light which shares in this Not-other characteristic, that of being<br />
self-defined. Only those who ask, “What is the cause of this process,”<br />
can come to discover this characteristic, a realization only<br />
obtained by having a clear concept of the cause.<br />
The history of modern science is founded upon this<br />
method.<br />
The lack of this approach is due to the fact that it has<br />
been replaced by a priori assumptions about physics, geometry,<br />
and mathematics; their presence acts in such a way, that although<br />
there have been many discoveries which have overthrown these<br />
assumptions, the shackles are continually re-fastenend, and new<br />
discoveries are re-stated in terms of the old ones, re-explained by<br />
what was known before.<br />
Like the old flame that keeps translating you back into<br />
the person which their fantasy first thought up when you just met,<br />
for the reductionists, nothing is really new.<br />
The Error of Archimedes<br />
This method of approach was founded in Cusa’s correction<br />
of the error of Archimedes in his attempt to square the<br />
circle.<br />
Cusa shows in his paper, On the Quadrature of the Circle,<br />
that the curvatures of the angles inside and outside the circle<br />
have an invisible difference which nonetheless exists, an essential<br />
characteristic which is the result of the kind of action which<br />
generates a circle, as the action which Kepler discovered generates<br />
the ellipse corresponded to a physical relationship present at<br />
every infinitesimal moment of the orbit. This defines the curved<br />
and straight lines partaking in those angles, as incomparable with<br />
one another.<br />
After noting this ‘species’ difference, he shows that from<br />
straight lines, it is impossible to determine the radius of a circle<br />
which would have an equal perimeter to a triangle, but, that one<br />
can come seemingly very close. This error of precision is pointed<br />
out by him as fundamental to the way in which the human mind,<br />
seeking to measure truth, must approach principles. 1<br />
1 “The measure with which man strives for the inquiry of truth has no<br />
rational proportion to Truth itself, and consequently, the person who<br />
Δυναμις Vol. 3 No. 3 December 2008<br />

Cusa wrote later in his<br />
Theological Complement, that<br />
the defining difference of his approach<br />
with Archimedes’ is based<br />
on the fundamental distinction<br />
between the rational and intellectual<br />
parts of the mind. He states<br />
in that location, that the gravest<br />
mistake of Archimedes was his<br />
reliance on his rationality to measure<br />
a principle only graspable<br />
in his intellect; the problem was<br />
not that in his mind he sought to<br />
measure the circle with a straight line, but that he endeavored to<br />
manifest this rationally. 2<br />
His point is best expressed by two different responses to<br />
the following question: how do you find the perimeter of a circle,<br />
whose measure is a straight line?<br />
Archimedes’ reply was to use an exhaustive method of<br />
approximation through bisection of arcs in comparing the straight<br />
to the curved. Cusa, however, answered that the real circle whose<br />
area is measured by a straight line exists only in the infinite.<br />
“The ancients sought after the squaring of a<br />
circle. 3 If they had sought after the circularizing of<br />
a square, they might have succeeded…a circle is not<br />
measured but measures… Given a finite straight-line,<br />
a finite circular-line will be its measure.<br />
“Thus, given an infinite circular line, an infinite<br />
straight-line will be the measure of the infinite<br />
circular-line… Because the infinite circular line is<br />
straight, the infinite straight-line is the true measure<br />
that measures the infinite circular-line…<br />
“Therefore, the coincidence of opposites is as<br />
is contented on this side of precision does not perceive the error.<br />
And therein do men differentiate themselves: these boast to have<br />
advanced to the complete precision, whose unattainability the wise<br />
recognize, so that those are the wiser, who know of their ignorance.”<br />
Nicholas of Cusa, from Toward a New Council of Florence, translated<br />
by William F. Wertz, Jr. (Schiller Institute: Wasthington, DC<br />
1993)<br />
2 Cusa writes: “But the coincidence of those features in every polygon<br />
in terms of a circle, ought to have been sought intellectually; and<br />
[then those inquirers] would have arrived at their goal.” The rationality<br />
determines the properties of a subject, such as a radius of a<br />
sphere, or the geometrical properties of a curve. The intellect, can<br />
conceive of the concept of an infinite sphere, where the center and<br />
circumference coincide, or, as the infinite circle, whose measure is a<br />
straight line. Cusa, ibid.<br />
3 Such as Archimedes<br />
The Calling of Elliptical Functions<br />
Kirsch<br />
the circumference of an infinite circle; and the difference<br />
between opposites is as the circumference of a<br />
finite polygon.” [emphasis added]<br />
Cusa’s solution is outside the comprehensibility of the<br />
rational, but exists in the intellect; in conceiving of the essence<br />
of a thing, the intellect brings the relations between different species<br />
to clarity; bringing the boundaries of a species into the understanding,<br />
it thereby illuminates the concept of a generating<br />
principle. 4<br />
In other words, a process such as a circle is the projection<br />
of an unseen principle, and thus the essence determining its<br />
uniqueness will be unseen. This process is known to the mind, not<br />
by describing the process (the arc of the circle), with its effects<br />
(the straight lines of the polygon), but only through the paradox<br />
of the infinite. Cusa’s concept of the infinite is that the mind must<br />
ascend to the generating principle, the principle of the not-other,<br />
to see that the principle of the circle defines itself.<br />
1. Descartes’ Fraud<br />
Holding this approach of Cusa in the mind, travel forward<br />
to beyond Kepler’s rigorous demonstration of Cusa’s method<br />
for the elliptical orbit, his own paradox in measuring such a<br />
curve, and his discovery of universal gravitation bounding the<br />
system of our sun. 5<br />
In his New Astronomy, Cusa’s follower Johannes Kepler<br />
had uncovered the physical paradox of constant change in the<br />
universe. This paradox he captured by determining the constant<br />
physical relationship governing the relation between the physical<br />
cause of the sun, and the sense perceptible observations of Tycho<br />
Brahe. As this relationship was found to take the form of an ellipse,<br />
it was accompanied by a problem he called upon future<br />
geometers to solve.<br />
In the aftermath of Kepler’s mortal death the networks<br />
of Descartes had attempted to remove the method of investigating<br />
physical paradoxes. By means of his limited powers of mind,<br />
Descartes announced a ban on such physical paradoxes as Kepler<br />
left for geometers, or, what he termed, ‘mechanical’ problems.<br />
4 Cusa had made this point in De Docta Ignorantia when he<br />
brought the infinite to mathematics. Cusa used the example of the<br />
infinite line to demonstrate that the maximum is in all things and all<br />
things are in the maximum. Each finite line could be divided endlessly<br />
and yet, a line would always remain. Thus the essence of the<br />
infinite line was in a finite line. Likewise each line, when extended<br />
infinitely, became equal, whether it was 4 feet or 2 feet. Thus the essence<br />
of each finite line was in the infinite line, although participated<br />
in by each finite line in different degrees. Here, the circle is in every<br />
polygon, in such a way that each polygon is in the circle. “The one<br />
is in the other, and there is one infinite perimeter of all.” http://cla.<br />

“Probably the real<br />
explanation of the refusal of<br />
ancient geometers to accept<br />
curves more complex than<br />
the conic sections lies in<br />
the fact that the first curves<br />
to which their attention was<br />
attracted happened to be the<br />
spiral, the quadratrix, and<br />
similar curves, which really<br />
do belong only to mechanics,<br />
and are not among the<br />
curves that I think should be<br />
included here [in geometry],<br />
since they must be conceived<br />
of as described by two separate<br />
movements whose relation<br />
does not admit of exact<br />
determination.” 6 [emphasis<br />
added]<br />
This means that geometry<br />
was not to be used in determining<br />
physical paradoxes. But, to say you can’t use geometry is<br />
to say you can’t know it, since geometry is the means by which<br />
we come to measure what something is and is not.<br />
Gottfried Leibniz, who like Kepler before him, had been<br />
in training to be a priest before devoting himself to the study<br />
of mathematical physics, exposed this fraud. The ‘mechanical’<br />
curves, as Descartes defined them, were indeed constructible, but<br />
only by rising above the assumptions of Descartes.<br />
Leibniz’s reply was the following:<br />
“If you wished to trace geometrically (that is<br />
by a constant and regulated motion) the Archimedean<br />
spiral, or the Quadratrix of the Ancients, you could do<br />
it without any difficulty by adjusting a straight line to a<br />
curve, in such a way that the rectilinear motion would<br />
be regulated from the circular motion. And that is why,<br />
contrary to what Descartes has done, I will not exclude<br />
such curves from geometry, because the lines which<br />
are so described are exact, and they involve properties<br />
which are very useful, and are adapted to transcendental<br />
magnitudes.”[emphasis added]<br />
In an earlier letter on the subject to Antoine Arnauld in<br />
1686, Leibniz further elaborates and clarifies this sentiment, saying<br />
that his new method provides the means of reducing transcendental<br />
“curves to calculation, and I hold that they must be<br />
received into geometry, whatever M. Descartes may say.<br />
“My reason is that there are analytical prob-<br />
6 From The Geometry of Rene Descartes Translated by Smith<br />
and Latham<br />
The Calling of Elliptical Functions<br />
Kirsch<br />
lems which are of no degree…e.g. to cut an angle in<br />
the incommensurable ratio of one straight line to another<br />
straight line….” 7 “… I show that the lines which<br />
Descartes would exclude from geometry depend upon<br />
equations which transcend algebraic degrees but are<br />
yet not beyond analysis, nor geometry. I therefore call<br />
the lines, which Descartes accepts, algebraic, because<br />
they are of a certain degree in an algebraic equation.<br />
The others I call transcendental.” [emphasis added]<br />
Circular and Exponential Transcendentals<br />
What made Leibniz’s method of constructing transcendentals<br />
with geometry possible, was, that unlike Cartesian geometry,<br />
which treats a geometrical image as a self-evident fixed object,<br />
Leibniz discovered the characteristic of change of a process<br />
to be its most essential nature. With this conception, combined<br />
with experimentation by means of moments of change in the geometry,<br />
the mind can discover patterns and lawfulness that lead<br />
to a realization about the constant relationship which is present at<br />
every moment of change, one that exists in each infinitesimally<br />
small interval, guiding the process of the sense perceptible effect.<br />
Inversely, the curve could then be constructed as an expression of<br />
that relationship acting as though infinite to each moment of generation<br />
of the curve, as from above. From this, the curve is known<br />
not as an a priori sense perceptible object, but as an expression of<br />
the unfolded relationship maintained at every moment. 8<br />
7 See Box 1<br />
8 See Box 2. A basic demonstration of the application of infinitesmal<br />
calculus can be easily be understood by means of the simple<br />
Δυναμις Vol. 3 No. 3 December 2008<br />
Box 1<br />
Bernoulli shows an example of Leibniz’s description of this transcendental relation<br />
in his lectures on the integral calculus. Since the expression for the circumference of<br />
a circle is 2 times Pi times the radius of the circle, then two circles, having radii which<br />
are in proportion to each other as two lines which are incommensurable, such as 1 and<br />
square root of 2, will have perimeters which are likewise incommensurable.<br />
Imagine a cycloidal curve, produced<br />
by two circles in such a relationship<br />
described, one rolling about the other.<br />
In such a case there will be no number<br />
of times the rolling circle will come back<br />
around to the same position, such that it<br />
would trace out a finite number of cycloidal<br />
curves; rather an infinite number of<br />
curves will be traced. The consequence of<br />
this is that an equation produced by the<br />
intersection of a line with these infinite<br />
number of curves will have an infinite<br />
number of roots, be of infinite degree, i.e.<br />
transcendental, and non-algebraic.<br />
5
This geometrical differential<br />
of change blasts the empiricism<br />
of object-fixated analysts 9 , and defines<br />
the calculus as a language of<br />
change, capable of communicating<br />
ideas about indivisible principles<br />
which lay invisible to processes,<br />
and yet exist as their cause.<br />
As a corollary of this general<br />
method, Leibniz showed how<br />
such ‘transcendental’ and other<br />
curves could be constructed by different<br />
means, for example, not directly,<br />
but by the quadrature of geometric<br />
curves.<br />

Think, what is the geometric relation<br />
of this curve?<br />
It is such that it always has 1 or a<br />
constant as the geometric mean between<br />
X and Y.<br />
Therefore, how do you create a<br />
geometric mean?<br />
Have you ever doubled a<br />
square?<br />
If yes, then you know what a<br />
geometric mean consists of and therefore<br />
will know where the constant would be<br />
between X and Y on the hyperbola.<br />
Did you figure it out yet?<br />
Ahh, well, I’ll give you the answer.<br />
It’s at half the angle between X and<br />
Y (in the top diagram, it is 45°). If you<br />
don’t know why, double a square, until<br />
you create a spiral. Then look at the properties<br />
of the spiral.<br />
This then remarkably gives us<br />
not only any X and Y relation, but also<br />
a tangent to the hyperbola of ½ X and Y,<br />
meaning that the point of the curve which<br />
is the tangent is at the coordinate ½ X<br />
and ½ Y (see the top diagram, in this case<br />
it is 2 for X and ⅛ for Y)<br />
Lets translate this now into mathematical<br />
mumbo jumbo and see why this<br />
works out according to Leibniz’s calculus<br />
of differential. Supposedly, the curve we found is the tangent, which means that it is<br />
the characteristic triangle of the curve or the dy<br />
dx = in X−2 terms of mathematics.<br />
Now, by way of the mathematics of the calculus, we know that the differential<br />
of Y = 1<br />
X is dy = X−2 dx or dy<br />
dx = X−2 . We also see that the triangle we find<br />
geometrically as the tangent has a length of X and a height of X−1 ; which means<br />
that the proportion is 1<br />
X 1<br />

Leibniz’s notation<br />
for the integration<br />
of curves showed<br />
that the expression for<br />
both the quadrature of<br />
the hyperbola and the<br />
arc length of a circle,<br />
as Cusa had indicated<br />
earlier, was indeed<br />
transcendental, and<br />
not able to be integrated<br />
algebraically 10 ;<br />
however, although<br />
transcendental, the<br />
integrals of the circle<br />
and hyperbola could<br />
be related to the physical<br />
function to which<br />
they correspond, and<br />
used to construct other<br />
transcendentals related<br />
to them. Therefore,<br />
although they<br />
themselves were not<br />
algebraically solvable<br />
with the Leibniz<br />
method of integration,<br />
the functions were<br />
known, and thus the<br />
concept of the construction<br />
was clear.<br />
In this way<br />
curves, such as conchoids,<br />
could be<br />
constructed from an<br />
equivalent area made<br />
up of a hyperbola and<br />
a circle, or, many oth-<br />
er transcendental curves, such as the exponential curve, could be<br />
constructed with two simultaneous actions.<br />
Maintaining a relationship between a constantly grow-<br />
10 The concept of integration depended on the relationship between<br />
the function and its change at every moment. Without such<br />
a relationship, the integral could not be found, e.g., in Box 4, the<br />
differential of the quantity under the square root, –2 x dx, is not the<br />
differential part of the expression, that is dx, and thus there is no<br />
means to integrate the expression, since there is not a direct relation<br />
between a quantity and its differential. (See Bernoulli’s Lectures on<br />
the Integral Calculus, Translated By Bill Ferguson, in this issue of<br />
Δυναμις.) For certain algebraic functions, many methods were used<br />
to solve integrals; however, for the transcendental curves, the only<br />
recourse was the ability to relate the differential to the actual function<br />
to which it corresponded.<br />

Bernoulli shows that the exponential curve,<br />
a transcendental of no degree, can be constructed by<br />
means of the quadrature of the hyperbola.<br />
Starting with the equation for the curve of constant<br />
subtangent(the characteristic of the exponential<br />
curve), dw:dz :: w:a, one sets up the equality a dz = a2 dw: w.<br />
Bernoulli then shows that when the equality of<br />
this relationship is maintained through all possible values<br />
of z and w, the exponential curve will be constructed.<br />
The integral � a2dw : w = az . To construct<br />
the left side of the equation, the z axis of the<br />
hyperbola has the lengths, a2<br />
w . This multiplied by<br />
the infinitesimally small change in w, gives us the area under the hyperbola. The area of the<br />
hyperbola grows arithmetically in proportion to the geometric growth of the w axis (as investigated<br />
by St. Vincent de Gregoire, 1 to<br />
whom Leibniz gives credit as one of his<br />
three major inspirations.) The right side<br />
of the equation, a dz, is a simple rectangular<br />
growth, whose sum would be az, a<br />
constant times the z azis.<br />
This area az maintaining its<br />
equality to the area of the quadrature<br />
of the hyperbola sum of a2 dw : w, will<br />
therefore, in arithmetic rectangles along<br />
the z axis, project geometric growth in<br />
the w axis, which is the exponential<br />
curve.<br />
So, the sum of a2 dw : w, the<br />
quadrature of the hyperbola, is the logarithm<br />
of w, that is, the logarithm of the<br />
geometric growth, w.<br />
1 See Bill Ferguson’s article, in the Upcoming Issue of Dynamis for more on St. Vincent.<br />
ing quadrature of one geometric curve on one axis, and the<br />
equality of a rectangular area on the other axis, produces two<br />
simultaneous actions which construct the relation on which the<br />
transcendental curve depends. An example of such a construction<br />
of a transcendental curve is the method of constructing the exponential<br />
curve by means of the quadrature of the hyperbola (Box<br />
3).Within this method, for calculation, the arclengths closely related<br />
to the quadrature of the circle could be converted to Arcsine<br />
and Arccosine, while the quadrature of the hyperbola could be<br />
converted to logarithms. This method, related to a whole class of<br />
transcendentals, was able to solve many problems not otherwise<br />
solvable using the algebraic rules of the integral calculus. 11<br />

Physical Transcendentals<br />
With this understanding<br />
of the infinitesimal<br />
calculus, the understanding<br />
of how to conceptualize<br />
processes, such as Cusa had<br />
indicated much earlier, was<br />
brought to a higher degree<br />
of maturity; however, the<br />
real breakthrough for science<br />
came with Leibniz’s<br />
investigation of physical<br />
transcendentals. The<br />
boundary of this domain of<br />
transcendentals was defined<br />
by the investigation of the<br />
physical principle existing<br />
ontologically outside the<br />
domain of the ‘geometric’<br />
transcendentals.<br />
This superior<br />
campaign waged by Leibniz<br />
in the method of conceptualizing<br />
processes, and<br />
capturing them for mankind,<br />
necessilarily leads<br />
us to introduce what may<br />

The expression for the arc length of the circle cannot be<br />
algebraically integrated using the rules of the integral<br />
calculus; this underscores its transcendental nature,<br />
as there is no way to capture the true meaning of the<br />
arc length by means of the sine and cosine expressed as<br />
the algebraic magnitude, x. What is shown here, is that<br />
the expression for the arc length can be simply turned<br />
into a certain amount of radians which are equal to<br />
the arc length. This is not ‘solving’ the integral from<br />
within the functions, but rather, simply stating what<br />
the arc length equals in terms of the circle itself. It is,<br />
in a sense a tautology: the arc length equals the arc<br />
length. This is easily seen if one substitutes Cosine v for<br />
x in the integral expression for s; the ratio of the value<br />
for d(cos υ)a : √ a 2 − cos υ 2 becomes simply dv, thus,<br />
υ = � dυ . As an example, if the angle is 60°, then the arc<br />

He held that all phenomena are only modifications of extension<br />
and should be explained by their properties, such as form, position,<br />
and motion---explaining all phenomena in terms of sense<br />
perceptible quantities. This “salvation from mysticism” 12 must<br />
be understood, as having been done with a full consciousness of<br />
Kepler’s already established method for defining causes beyond<br />
extension.<br />
Descartes doctrine of extension thereby reduced the<br />
study of bodies in motion to purely geometric analysis, as Ptolemy<br />
had done before him. Causes were, not outrightly ‘denied’, but,<br />
in end effect, located, without reason, in the bodies themselves;<br />
‘causes’ explained by mathematical laws such as Descartes rules<br />
for motion or Ptolemy’s epicycles. 13 In this way, no experiments<br />
12 It is common jargon, that Descartes modernized physics to<br />
have replaced what was seen as the ancient Greek, mystical explanations<br />
of the ‘substance’ of bodies.<br />
13 This is an entirely different meaning of ‘self-defined’. From<br />
Descartes’ reasoning one might be led to believe that after mankind<br />
was freed from his body, they would be free from his ideas. If only<br />
this were so in the case of Descartes! (See Δυναμις exclusive interview<br />
with Descartes, this issue) For a concise exposition of the<br />
absurdity of Descartes’ rules of motion based on his maxim, the<br />

are necessary in physics, but rather, everything is deduced from a<br />
priori axioms about geometry.<br />
This is the battle field upon which Leibniz must be understood.<br />
Taking this into account, we will look at two physical<br />
transcendentals, one which ontologically defined the whole domain<br />
of transcendentals just discussed, and a second, posed by<br />
Leibniz, which leads us into the discoveries of Gauss and Riemann.<br />
2. Experimental Metaphysics<br />
It is important to make the point here at the outset, that<br />
the following detailed elaboration, seeming to some as an extended<br />
tangent to our current arc of thought, is in fact a crucial<br />
element defining the entire pathway of our methodological discussion.<br />
Leibniz’s method, described above, of finding the relationship<br />
maintained throughout the curve – the differential relationship<br />
– took on a different challenge in application to the<br />
catenary, the curve formed by a hanging chain. 14 As with curves<br />
such as the parabola, a constant relationship is sought which is<br />
present throughout the curve; however, in the case of the hanging<br />
chain, the constant relation is a physical one, not geometric.<br />
The catenary is formed by the tension between two tensions:<br />
the weight of the chain tending in the vertical direction 15 ,<br />
and the horizontal tension amongst the links themselves. The<br />
distance between the end links that hang the catenary defines the<br />
amount of horizontal tension that exists throughout the chain,<br />
and thus the differentiation between catenaries for any particular<br />
length of chain.<br />
Through physical experiment, the proportion of vertical<br />
and horizontal tension at a given point in the chain is found to be<br />
directly related to the direction which the chain is tending at that<br />
point. What is added to this derived fact, is the most essential<br />
property of the catenary: the horizontal tension is constant for<br />
any one particular catenary hung between two points, regardless<br />
of the amount of chain that is removed.<br />
These experimentally derived relations lead the physicist<br />
to traverse from the seen to the unseen, in order to investigate<br />
quantity of motion, see the October 2006 of Dynamis: Experimental<br />
Metaphysics, Kirsch, Yule, ft: 17. Also, in the same Issue, Inertia of<br />
Descartes Mind, Ross. See Fermat Book on Light, Ross.<br />
14 Jacob Bernoulli, posed this challenge at the end of his response<br />
to Leibniz’s Isochrone challenge of 1689, which was put forward<br />
to expose the Cartesian fraud in physics and geometry.<br />
15 There are assumptions brought to investigating physical<br />
curves from geometry with which we must dispense. First of all,<br />
directions are not arbitrary, lying on an infinite space of many directions,<br />
rather, they are physically defined. What is down? Down<br />
corresponds to the direction which a weight falls, and horizontal is<br />
that which is perpendicular to a falling weight. Any other definition<br />
is arbitrary.<br />
Δυναμις Vol. 3 No. 3 December 2008<br />

the changing relation at every moment of change. If the direction<br />
at two moments of the chain are extended by means of tangents,<br />
and the weight of the chain is placed where the tangents meet, the<br />
problem of measuring the relation, of horizontal and vertical tension<br />
in the chain, can be turned into another relation proportional<br />
to trigonometric functions created by the tangents. 16<br />
Employing this, a unique singular moment where the direction<br />
of one of the tangents is completely horizontal, turns the<br />
just mentioned relation into one relating the vertical tension of<br />
16 See Box 6<br />
Box 6a<br />
Box 6b<br />

Kirsch<br />
the whole chain, to the horizontal tension. 17<br />
The physical relationship of tensions guiding<br />
the change in direction at every moment of the<br />
curve is discovered: for any given length of chain,<br />
the proportion which represents the vertical and horizontal<br />
slope of the curve at that point, is equal to the<br />
proportion of the weight of the chain to the constant<br />
horizontal tension. 18<br />
Once the physical differential was discovered,<br />
both Leibniz and Johann Bernoulli saw its relation<br />
to the quadrature of the Hyperbola. From there<br />
however, their methods were entirely different.<br />
The most essential characteristic of the<br />
curve, the constant horizontal tension, makes the<br />
catenary the best expression of how nature performs<br />
the least action pathway in traversing space, thus defining,<br />
in its expression, the curvature of gravity and<br />
tension in bodies moving around the sun. This characteristic<br />
plays the main role in unfolding the unseen,<br />
physical paradox of this curve of least action. Here<br />
we come<br />
to the moment<br />
of<br />
inflection<br />
which leads to<br />

through utilizing<br />
the physical<br />
relations of the<br />
curve, dumping<br />
all axiomatic<br />
systems in the garbage.<br />
Going to the immediate point: how would one measure<br />
the height of a catenary? In order to measure the coordinates<br />
of the curve, where does one place the abscissa, the horizontal<br />
line beneath the curve? Should it be tangent to the bottom point?<br />
Somewhere below? If so, where?<br />
There is only one non-arbitrary distance below the curve<br />
to construct and measure the changing heights of the catenary:<br />
the length, one. But what length is one? The relation of vertical<br />
and horizontal tensions in the chain, to the vertical and horizontal<br />
direction, leads to a singularity at a tangent of 45°, where the proportion<br />
of vertical and horizontal direction is equal to one. 19 This<br />
length of chain is thus equal to the constant horizontal tension,<br />
the unit length, defined by the physical principle of the catenary<br />
itself.<br />
Only this intrinsic measurement, constructed under the<br />
catenary as the height of the abscissa, led Leibniz to discover the<br />
relation of the catenary to the quadrature of the hyperbola.<br />
As soon as he investigated, experimentally, the growing<br />
lengths of chain laid down straight as lengths at the bottom of the<br />
catenary the physical differential of the tensions was revealed in<br />
a new light. Investigating the diagonals of the triangle whose two<br />
sides are 1) the horizontal constant, which is set as the height<br />
at the bottom of the curve, and 2), the length of chain laid down<br />
straight, he then discovered these diagonals to be equal in length<br />
to the heights corresponding to that given length of chain.<br />
This points to the most essential corollary of these relations.<br />
In utilizing the square Pythagorean theorem, for these<br />
three sides—the diagonals (heights), constant tension (constant<br />
side), and length of chain (long side)—the physical differential<br />
relation 20 was transformed into one expressing the differential in<br />
terms of the quadrature of the hyperbola. 21<br />

However,<br />
unlike Bernoulli’s<br />

employing his knowledge<br />
of the relation of<br />
the exponential curve<br />
to the quadrature of<br />
the hyperbola, 22 inverted<br />
and translated<br />
this particular relation<br />
for y, in the above<br />
diagram, into one for<br />
x, showing the height<br />
of the catenary to be<br />
the arithmetic mean<br />
between two exponential<br />
curves. 23<br />
In other words, Bernoulli showed the catenary could be<br />
drawn with the quadrature of the hyperbola, but Leibniz showed<br />
that the inverse function for the quadrature of the hyperbola is the<br />
catenary. 24<br />
By this means, the substance of the catenary defined its<br />
own predicates, by its physical principle alone. Every effect of<br />
the physical differential is given definition, as a function of two<br />
transcendental functions. 25<br />

24 Johann realized, which his brother Jacob failed to do, that it<br />
was indeed a transcendental curve, and not algebraic, a discovery<br />
which recruited him to Leibniz’s method of seeking for the ironies in<br />
nature, as for example, his Brachristicone; however, his construction<br />
was inferior to Leibniz’s and did not leave the domain of the earlier,<br />
“geometric” transcendentals discussed, thus failing to capture a sub-<br />
stantial irony involved in the paradox of physical least action.<br />

In the fantasy of his own mind,<br />
Descartes imagined a physics based only on<br />
extension, one which required only a priori<br />
geometrical deduction without experimentation,<br />
i.e. an infinitely boring universe in which<br />
nothing new ever happens. On the contrary,<br />
in physics, a concept of the individual substance,<br />
or monad, is possible, a concept which<br />
is “so complete that it is sufficient to make us<br />
understand and deduce from it all the predicates<br />
of the subject to which the concept is<br />
attributed” 26 —provided one exists in the real<br />
universe of experimental metaphysics.<br />
The Power of Leibniz’s Construction<br />
Shattering the domain of Cartesian<br />
geometry and space, Leibniz’s construction<br />
captures, in the most accurate<br />
paradoxical metaphor, the unique irony<br />
between geometry and physics.<br />
All curves which could be described<br />
by one ‘coordinate system,’ an<br />
action defining a geometric space, are<br />
now seen to be inferior to those like the<br />
catenary which require two independent<br />
geometries. His construction points one<br />
in the direction of asking: doesn’t the<br />
catenary substantiate and define the existence<br />
of the exponential curve? That is, since the catenary is<br />
generated so easily by nature, and from it is derived two exponential<br />
curves, doesn’t only the physical least action of the catenary<br />
define the domain in which this relation of exponential curves<br />
exists?<br />
And further, doesn’t the creation of two exponential<br />
curves in opposite directions mean that one exponential curve is<br />
only a special case of the two, making the two together a single<br />
higher function, and in fact primary, defined ontologically by their<br />
generation by least action in the field of gravity and tension?<br />
In this sense, one is not putting geometric curves together<br />
in Cartesian space, but rather, a single unified physical principle<br />
is generating a geometric space—a different geometry of<br />
physical space altogether. It is not that the catenary can be drawn<br />
by the hyperbola or exponential, but rather, the catenary, is what<br />
draws the other curves. The physical principle thus defines geometry<br />
in a paradoxical manner, a geometry which goes beyond<br />
rived from the catenary are those whose logarithms are natural, i.e.<br />
the subtangents of the exponential curves are equal to one, or better<br />
said, whose subtangents are equal to the constant tension in the catenary<br />
itself.<br />
26 Gottfried Leibniz, Discourse on Metaphysics, Section VIII<br />
The Calling of Elliptical Functions<br />
Kirsch<br />
Descartes.<br />
To elaborate this point further, think back<br />
to Johann Bernoulli’s demonstration of constructing<br />
the exponential curve by means of the quadrature<br />
of the equilateral hyperbola. The right cone, to<br />
which this equilateral hyperbola would belong as a<br />
conic section, would, in order to create the double<br />
exponential construction of Leibniz, have to be<br />
joined with another right cone. Therefore, whereas<br />
in sense perceptible, descriptive geometry there exists<br />
one cone, in physics, there exist two cones set<br />
at 90 degrees to one another.<br />
Looking back upon geometry and ‘geometric’<br />
transcendentals from the standpoint<br />
of Leibniz’s catenary, one asks: doesn’t this<br />
mean that all prior analysis that didn’t involve<br />
physics was only a special case of sense perceptible<br />
geometry, not the kind which subsumes<br />
the true nature and characteristics of<br />
the functions?<br />
Even more specifically: Leibniz’s<br />
discovery redefines ontologically, the whole<br />
domain of the quadrature of the circle and<br />
hyperbola, and all the lower geometric curves<br />
which could be constructed by quadrature. 27<br />
The physical action is primary and generates,<br />
as a lower domain, the predicates of geometrically<br />
related quadrature. In this way, the circular<br />
and logarithmic are in a sense geometric<br />
transcendentals; they are not related to physical transcendentals<br />
directly, but only indirectly, existing as their effects and projected<br />
shadows.<br />
The catenary’s relation with the quadrature of the hyperbola<br />
shows that the transcendental quadratures were sufficient for<br />
describing certain processes, but Leibniz shows their limitation,<br />
by bringing the concept of the transcendental to a higher domain,<br />
a domain which corresponds to least action, expressing principles<br />
organizing the space of gravity and tension.<br />
Above all, Leibniz’s method of discovery demonstrated<br />
the Not-other characteristic of the catenary---a discovery possible<br />
only with the intrinsic physical geometry defined by the process<br />
27 This is also demonstrated in the case of Leibniz’s quadrature<br />
machine, where the tractrix, the evolute of the catenary, is used<br />
as a generalized quadrature principle. See Extension of geometric<br />

itself. He demonstrated the way in which the mind can be elevated<br />
to an understanding of this characteristic, by discovering<br />
the geometrical principle which expresses ironically the physical<br />
principle at every moment. The truest expression of reality is the<br />
irony with which the relation between the predicates, points to the<br />
truth that the process defines the predicates.<br />
And thereby, it is this type of domain in which intellectual<br />
ideas truly exist.<br />
It is the transformation between domains, which gives<br />
a power to man, and pushes his ability to new degrees. In this<br />
sense, there is not an object which one can see as the transcendental,<br />
only an effect is seen. The transcendental is only present<br />
in the mind, seen as an anomaly between what is yet undiscovered<br />
and what is known and yet transformed ontologically by the fact<br />
of the existence of the transcendental.<br />
In this sense, for those who do not ask “why?” when<br />
confronted with a paradox to their preconceived notions, the<br />
transcendental does not exist.<br />
3. Descartes’ Fraud, Again<br />
We saw above that the differential expressions for the<br />
quadrature of the circle and hyperbola could not be integrated<br />
but could be related to their known physical functions. Yes, these<br />
transcendental expressions were a rigorously true definition for<br />
the area of the curve, but not indicative of how they were generated,<br />
i.e. of the domain to which they actually corresponded.<br />
However, there were other physical transcendentals<br />
which couldn’t be related in any way to known functions, not<br />
even in the way that the catenary is ‘related’ to quadrature of the<br />
hyperbola.<br />
Accordingly, Leibniz had his own challenge for scientists<br />
which, in his lifetime, did not become solved to a sufficient<br />
degree. He posed a challenge of constructing a curve which<br />
couldn’t be related in any way to the quadrature of the circle and<br />
hyperbola, and thus posed a completely new test for physicists.<br />
Like Kepler’s elliptical orbit, what Johann Bernoulli called the<br />
integrals of “elliptical” curves, left a challenge. A true solution<br />
to them would not be solved in his life time by him nor the Bernoullis<br />
and would lead to the paradox of what Johann Bernoulli<br />
called the ‘elliptical’ integral. As Carl Gauss himself would later<br />
say, it is this domain beyond the shadows of the quadrature of the<br />
circle and hyperbola that is of essential interest to those who seek<br />
to open up new domains of thought. 28<br />
28 “In the computation of integrals I have always had little interest<br />
in matters that simply follow from substitutions, transformations,<br />
etc.--in short, making use of a certain mechanism in an appropriate<br />
way to transform integrals into algebraic, logarithmic, or circular<br />
functions; instead, my real interest has been a more careful and deep<br />
consideration of transcendental functions that cannot be transformed<br />
into those named above. We can now deal with logarithmic and circular<br />
functions as we can with 1 times 1, but that lovely goldmine<br />
that contains the higher functions is still almost completely terra<br />
incognita. …One stands in awe before the overflowing treasure of<br />

However, the gateway to this new domain of study involves<br />
an often missed, but crucial, historical irony.<br />
Among most scholars of science and mathematics today,<br />
there is little understanding that higher analysis in geometry originated<br />
from the overturning of Descartes’ ban on transcendentals.<br />
But what is even less understood today, is that the development<br />
of the analysis of what came to be known as ‘elliptical’ integrals,<br />
was born directly out of the instance of Leibniz’s incorporating<br />
his method of transcendental physical curves into his fight against<br />
the Cartesian ‘physicists’. The weight of this historical truth is<br />
necessary for comprehending the tensions within the body of<br />
knowledge discovered by Carl Gauss and Bernhard Riemann.<br />
Leibniz’s Dynamics<br />
In 1686, Leibniz exposed the fraud of Descartes’ quantity<br />
of motion, causing an irrational freak out by a well known<br />
Cartesian, Abbott Catalan 29 ; despite further correspondence on<br />
the subject, his cult-like belief in Descartes would not be challenged.<br />
30 Understanding the steps one takes to determine a new<br />
paradoxical proposition, Leibniz consciously recruited others to<br />
his method by posing a challenge whose solution required the<br />
discovery of a new principle or the application of a new method.<br />
In 1689, Leibniz challenged those infected by Cartesian<br />
methods to solve both the simple isochrone, (the curve a body<br />
would take traveling equal vertical distances in equal times) 31 ,<br />
and the paracentric isochrone (the curve a body would take receding<br />
equal distances from a given point in equal times), knowing<br />
that only those who surpassed the dogma of Descartes could approach<br />
the problem.<br />
The political guts of Leibniz, and the realization of the<br />
uniqueness of his method, inspired the Bernoullis to take up the<br />
challenge of these isochrones, and led in end effect to a movement<br />
of scientists who could demonstrate, simultaneously, the fallacy<br />
of both Descartes’ physics and his ban on applying geometry to<br />
mechanical curves. 32<br />

The Paracentric Isochrone<br />
The Calling of Elliptical Functions<br />
Kirsch<br />
The paracentric isochrone is the curve<br />
formed by a body which moves away from a<br />
given point in equal distances corresponding to<br />
equal times. To construct such a curve requires<br />
a method of inversion. Rather than having a<br />
curve, and determining its physical properties,<br />
as with the catenary or elastic curve, this curve<br />
is found as the solution to the aforesaid physical<br />
properties.<br />
The body is dropped from a height i,<br />
the radius of the circle in the diagram. Since the<br />
property is traveling equal distances in equal<br />
times away from a point, once the body reaches<br />
the start of the curve at A, it will fall the same<br />
distance away from A at the first moment of the<br />
curve, as it will in a moment along any other<br />
part of the curve. This important fact is combined<br />
with two other known laws of motion, to<br />
lead to transcendental relation which is to be<br />
constructed.<br />
First, the relationship between the speed<br />
at the first moment to the speed at the second moment is proportional to the proportion of the two distances traveled at<br />
those moments. Secondly, the squares of the speeds are proportional to the vertical distances fallen. This means that the<br />
squares of the proportion of the distances traveled at two moments, are directly proportional to vertical distances from<br />
which they have fallen. Obtaining a representation of this proportion is our first step.<br />
In our diagram, call Aw the infinitely small distance fallen at the first moment of the curve, δα distance traveled<br />
in a moment at some other point δ of the curve. The distance βα, is the change in the distance of the body from the<br />
given point A, in the time it travels form from point δ to an infinitely small distance away point α. From what was said,<br />
this distance is equal to Aw. Therefore, as Aw<br />
βα<br />
equals the speed of the body at A to the speed at δ, so equals the same<br />

In Bernoulli’s 1694 paper on the elastic curve, he compares the relation of the tension in an elastic band, to its<br />
length, and the width of the band to its stretching. He also compares the length of the band to a small element, and the<br />
radius of curvature to its stretching. By comparison of these two relations, he determines a transcendental relation,<br />
which he proceeds to construct by an elaborate method of quadrature, similar to that in Box 3, but much more complicated.<br />
Through this, he is able to construct the elastic curve, the arc of which AQ, is found to be equal to �<br />
In comparison of his two constructions, one for the paracentric, and one for the elastic curve, he finds that the<br />
mean z is the third proportional of a and u, the abscissa of the elastic curve, or in other words, z = uu<br />

By the acceptance of this challenge, physical transcendental<br />
curves were now opened to be studied. What this signified<br />
was a decisive defeat for the Cartesian method, and also an opening<br />
to a new domain.<br />
Jacob’s solution to “Leibniz’s Curve”<br />
The differential relationship of the paracentric isochrone<br />
led to a form similar to the differential expression for the quadrature<br />
of the circle and hyperbola, i.e., a transcendental one. 33 However,<br />
unlike those, and related others, there was no way to relate<br />
the paracentric isochrone to any known, constructible functions.<br />
In the construction of such a curve, Jacob tried to uncover<br />
the identity of this curve by enticing relatives of the curve, and<br />
seeing if they would, as though spilling the family dirt, help in<br />
identifying its true character. In this way, he found the integral of<br />
the paracentric was directly related to the elastic curve, the curve<br />
of a bent flexible rod, whose integral rises to the fourth degree. 34<br />

1 Bernoulli’s original diagram included a hyperbola on either side of the lemniscate.<br />
1<br />
However, due to the non-constant ‘law<br />
of tensions’ which the elastic curve obeys, another<br />
curve would have to be used. 35 Jacob found<br />
a saving grace. He writes “as if from a prayer, a<br />
curve of four dimensions presents itself” shaped<br />
like “the bow of a French ribbon.” This curve<br />
was the lemniscate, which, by employing it instead<br />
of the elastic curve, since the expression<br />
for their arclengths are identical, he could turn a<br />
quadrature into a rectification. 36 In relating these<br />
curves to one another, Jacob came upon an interesting<br />
relation between the ellipse, lemniscate,<br />
and elastic curve. 37<br />
But, as the elastic curve and lemniscate<br />
were themselves only described in terms of the<br />
functions they produced, relating such curves<br />
to the paracentric isochrone did not reveal the<br />
identity of such an integral. The problem was,<br />
all the relatives shared in the family secret; they<br />
only posed new paradoxes, leaving as a mystery<br />
the principle involved in these higher transcendentals.<br />
One is left asking: what was the principle<br />
which created the process of the paracentric<br />
isochrone, and its relatives? What was the<br />
process to which these predicates correspond?<br />
Such was the boundary of this higher transcendental.<br />
But, just as the quadrature of the hyperbola needed to<br />
be ontologically defined by a higher transcendental of a different<br />
species, the catenary, so the ‘elliptical’ integrals of the lemniscate<br />
and elastic curve, related to the paracentric isochrone, demanded<br />
to be defined by a higher domain. What seemingly was limited<br />
to physics was in fact an impassable barrier into the realm of the<br />
principles of space.<br />
Looking back from the origin which led to the study of<br />
‘elliptical’ integrals, as Bernoulli referred to them, it is seen that<br />
Descartes’ absurd physics had an ironic effect of rendering the<br />
investigation of transcendental physical processes, and the functions<br />
related to them, impossible. Leibniz’s method of dynamics<br />

thus opened the door to the confrontation with the essential, and<br />
aggravating problem of dealing with physically related transcendental<br />
pathways of four dimensions.<br />
A Great Frustration<br />
The one crucial, actual discovery in the study of elliptical<br />
integrals occurring before the time of Gauss, was made by the<br />
Italian, Giulio Carlo Fagnano, who had been studying philosophy<br />
and theology before devoting himself to the study of geometry,<br />
particularly, the investigations of the Lemniscate.<br />
He begins his most famous work Metodo per Misuare<br />
La Lemniscata, thus:<br />
“The two greatest geometers, the brothers 1<br />
Giacomo (Jacob) and Giovanni (John) Bernoulli have<br />
made the lemniscate famous, using its arcs to construct<br />
the paracentric isochrone”.<br />

Gauss compared ON arcs =sinlemn on the lemniscate, q with arcs on the circle. As<br />
Gauss noted in his Om notebook, =coslemn the ptangent<br />
of an angle from the center<br />
of the lemniscate, On =coslemn equals the qlemniscatic<br />
cosine at that angle.<br />
So inspired by<br />
‘Leibniz’s curve’, Fagnano<br />
discovered fundamental<br />
principle’s.<br />
First, what is the algebraic<br />
relation between<br />
the functions related to<br />
complementary (opposite)<br />
arcs of the curve?<br />
This involves a geometrical<br />
relation with<br />
the tangent taken at a<br />
unique singularity of<br />
the curve, allowing one<br />
to compare the angles of<br />
the relevant functions.<br />
Second, as multiple arcs of the lemniscate are traversed,<br />
what is the algebraic relation between the functions of the<br />
curve? 38<br />
The origins of Fagnano’s discovery are still to<br />
be uncovered by intrepid discoverers; only passing clues<br />
are left in his two part paper, Metodo per Misuare La<br />
Lemniscata. In his first work, he presents a relation between<br />
the equilateral hyperbola, ellipse, and lemniscate,<br />
in a diagram very similar to Jacob’s construction for the<br />
paracentric isochrone. Fagnano states that his complementary<br />
arcs principle was discovered by him in relation<br />
to rectifiying the arcs of a certain parabola. In connection<br />
with his second principle of multiple arcs, he states that<br />
the measure of the lemniscate depends on the extension of<br />
the equilateral hyperbola and a type of ellipse, while the<br />
measure of the cubic parabola depends on the extension<br />
of the lemiscate. This echoes Jacob’s construction noted<br />
above. 39<br />
With the combination of these two principles,<br />
Fagnano showed how to divided the Lemniscate into equal parts,<br />
such as 2,3,5 parts; and generally divisions which fall under 2<br />
times 2 to the m, 3 times 2 to the m, 5 times 2 to the m, where the<br />
exponent m represents any positive whole number.<br />
These discoveries by Fagnano were crucial, as they made<br />
clear certain relations between the curve itself, and the functions<br />
produced by the curve. This at least allowed the shadows, which<br />
the higher transcendental generated, to form a pattern with which<br />
to work. However, although Leonard Euler generalized the relation<br />
of multiple arcs to their functions, which became known<br />
as the ‘addition theorem’, the principle of organization was still<br />
38 See Box 11.<br />
39 Fagnano then references its relation to a paper in the Acta Eruditorum<br />
of 1695, concering the division of the Cubic Parabola. The<br />
cubic parabola was the solution to the first isochrone challenge given<br />
by Leibniz in 1 1689, and Jacob Bernoulli had investigated dividing it<br />
into equal arcs.<br />

The Calling of Elliptical Functions<br />
Kirsch<br />
Series approximations of the Lemniscate integral<br />
by Stirling and Euler, as noted in Carl Gauss’s notebooks<br />
completely unknown 40 ; the cause which generated the process,<br />
created a great frustration looming over the cognizant minds who<br />
attempted the search.<br />
4. Removing the Training Wheels<br />
Carl Gauss’s daily log and notes from January 1797<br />
through fall of 1798, maps out the discovery of a new field of<br />
science involving the nature of the Lemniscate. 41<br />
Gauss began with the methods of his predecessors, but<br />
looked at the same function with completely different eyes. His<br />
notebooks show that he read everything by Euler on the Lemniscate<br />
related to his elaborations of Fagnano’s discoveries, such<br />
as his Observationes de Comparatione Arcuum Curuarum Irrectificabilium.<br />
He also tackled the many works on determining<br />
values of transcendentals with infinite series. For example, John<br />
Stirling’s De summatione et interpolatione serierum and Leonard<br />
Euler’s, De Miris Proprietatibus Curvae Elasticae, the latter<br />
written specifically on finding infinite series for the lemniscate<br />
integral.<br />
However, he wasn’t interested in these methods because<br />
they were only good for finding numerical values. Unlike Euler,<br />
who treated the expression for the lemniscate as a complicated<br />
algebraic expression, which merely begged a numerical approximation<br />
by series, Gauss had something else in mind when consid-<br />
40 When Fagnano was nominated to the Berlin Academy in 1750, he<br />
sent the Academy a copy of his Produzione Matematiche which<br />
reached Euler’s hands on 23rd December 1751, a day described by<br />
Jacobi as “the birthday of elliptical functions”. However, in the papers<br />
he would present to the academy in the following years on the<br />
subject of the lemniscate addition theorem, Euler’s work was nothing<br />
more than an elaboration of the implications of Fagnano’s discoveries;<br />
Euler himself made no original discoveries of his own. Euler,<br />
who did nothing more than take the insights of Fagnano and fill them<br />
out, was led to great fame, and is today considered one of the great<br />
geniuses in mathematics. Fagnano, an actual genius, is held in obscurity,<br />
barely known by the recipients of his original discoveries.<br />

ering this function, and simply<br />
utilized the methods of series for<br />
a different task. For Gauss, the<br />
paradox of elliptical integrals<br />
served as a tool to open up a new<br />
domain of truths, a new instrument<br />
for experimentation, not a<br />
paradox to be reduced back into<br />
something relatable to so-called<br />
known domains, as Euler had<br />
exhaustively attempted to do.<br />
In this spirit, Gauss<br />
deviated from the prior method<br />
of Fagnano and treated the lemniscate<br />
problem, not as an algebraic relation of functions whose<br />
complementary arcs are arithmetically related, but as a periodic<br />
function (what he called the sine and cosine of the lemniscate). 42<br />
With this understanding of the periodic Sine and Cosine<br />
of the lemniscate, Gauss proceeded along a new path, untread.<br />
Gauss, unlike all his earlier predecessors, investigated not how<br />
the ‘elliptical integrals’ could be expressed in terms of their functions,<br />
but rather, what is the process such that it defines these<br />
particular predicates.<br />
To clarify the point: just as the sine and cosine of a circle<br />
are the trigonometric functions of the arc of the circle, so the sine<br />
and cosine of the lemniscate, an ‘elliptical’ integral, are the ‘elliptical’<br />
functions of the arc of the lemniscate.<br />
Therefore, the question restated in another way is: rather<br />
than investigating how the elliptical integral could be defined<br />
as a function of its functions, Gauss asked, how can the elliptical<br />
function be defined as a function of elliptical integrals? The<br />
process is thus investigated not by what it generates, but how it<br />
generates it, i.e., by looking at the way the function of elliptical<br />
integrals can express the elliptical function, he asked the question:<br />
how does the process, define itself?<br />

function, expressed as quotients of infinite products and<br />

The Calling of Elliptical Functions<br />
Kirsch<br />
Box 11<br />
Zeroes and Infinities<br />
Gauss was more interested in finding how the function<br />
itself acts, rather than finding infinite series approximations.<br />
In other words, Gauss was searching for singular<br />
characteristics of the function, to distinguish it from others.<br />
Take an average, everyday transcendental function, such<br />
as the sine of an angle. What are some singular properties<br />
of the sine function? The function continuously changes,<br />
as its radius moves around the arc of a circle, but it has a<br />
maximum and a minimum – positive 1 and negative 1, respectively.<br />
It also traverses zero twice in its period around<br />
the circle. Its change is non-constant, so it is impossible<br />
to determine its exact length, in terms of the diameter of<br />
its circle, except at those singular points and a few others.<br />
We can begin to develop a mathematical expression of<br />
those singular points, in hopes of defining our function<br />
with them.<br />
In 1799, Gauss proved beyond a doubt that, since<br />
algebra is merely a description of a real physics, an algebraic<br />
equation was always decomposable into a number<br />
of factors equal to the highest degree of the equation.<br />
Each of these factors represent where the equation is<br />
zero. So, the equation x2 − 4=0<br />

π2 4π2 9π2 (1 − x4<br />
π4 has two zeroes: at positive<br />
and negative 2. Therefore, it can also be written as<br />
(x − 2)(x +2)=0 .<br />
Every algebraic equation has a finite number of<br />
zeroes, and thus factors, but our sine function is transcendental,<br />
thus having an infinite number of zeroes. Therefore,<br />
we can attempt to approximate our sine, using an algebraic<br />
equation with an infinite number of factors. Since the<br />
zeroes are all at integral numbers of half-circumferences<br />
(0, π, 2π, 3π,..., −π, −2π, −3π,... ), we can write:<br />
Now, whenever the arc x is equal to a denominator,<br />
that factor will become zero, and we have a zero of<br />
the function. Try it out for some<br />
)<br />
non-singular point, such<br />
as x =1 radian (2π radians = 360◦ ). Our function gives<br />
1(1 − 1<br />
every time it traverses one lobe of the lemniscate. Therefore,<br />
when x is 0, Π, 2Π, 3Π,..., −Π, −2Π, −3Π,... ,<br />
the lemniscate function is zero. Our function<br />
should, therefore, look much like the sine function:<br />
Let’s see what Gauss really said:<br />
OK, now this looks a bit different than what we<br />
found. Let’s analyze it. First, instead of (1 −<br />
1 1<br />
1 1 1<br />
π )(1 − 2π )(1 − 3π ) ···(1 + π )(1 + 2π )(1 + 3π ) ···<br />
etc., which will be, approximately, 0.866054044. The actual<br />
sine of one radian is more like 0.8414709848, which<br />
is pretty close.<br />
Gauss applies this reasoning to the lemniscate<br />
1<br />
function. If the lemniscate function is the radius of the<br />
lemniscate, and its variable is the arclength of the lemniscate<br />
x, then we can find its zeroes. The radius is zero<br />
x<br />
Π ) , Gauss<br />
has (1 − x4<br />
Π4 x<br />
) . Second, if you look closer, Gauss actually<br />
has written down a ratio, with denominator terms.<br />
Still, if the arc is equal to some whole number of lobes, Gauss’s<br />
function equals zero. But, what if any of the factors in the denominator<br />
equal zero? Then, this function expresses where<br />
the lemniscate function is infinity! Where on the lemniscate,<br />
is its radius infinite? Nowhere! What is Gauss doing here?<br />

one.) Gauss would also write, for the good old circular<br />

Lagrange’s Inverse Function<br />
Continuing to utilize the mathematical<br />
apparatus of his predecessors,<br />
Gauss capitalized on the Lagrange inverse<br />
theorem to get an expression for<br />
the inverse function for the lemniscate,<br />
i.e. if by some variable y, we denote the<br />
arc length of the lemniscate which is a<br />
function of some variable x, then how<br />
can we express x, in terms of a function<br />
of y?<br />
At left is an algebraic infinite series<br />
approximation of the inverse function,<br />
revealing nothing too profound<br />
about the nature of x.<br />
Where Lagrange used<br />
his inverse function to simply<br />
get a numerical expression for<br />
the function he was looking at,<br />
Gauss was using the inverse<br />
function as a means, a stepping<br />
stone for a more elaborate investigation<br />
into the nature of<br />
the function, using calculations<br />
to determine what the inverse<br />
function does.<br />
Since Gauss looked upon the<br />
sine and cosine of the lemniscate as real<br />
functions, not simply numerical quantities,<br />
he experimented with them, and<br />
looked at how they change taking their<br />
derivatives, and reciprocals, to determine<br />
the properties of the function. This<br />
stands in contrast to Euler, who looked<br />
at the function as a magical box, where<br />
one puts something in, and gets something<br />
out.<br />
The uniqueness of Gauss’s investigation<br />
here can also be seen as he<br />
finds, in an analogy to the circle, the tangent<br />
and the derivative of the tangent.<br />
But wait – on the visible lemniscate, as<br />
we saw above in Box 9 on Fagnano’s<br />
use of the tangent, there is no ‘tangent’<br />
of the lemniscate, because it equals the<br />
sine and cosine of the lemniscate!<br />

One asks, “But how<br />
can these functions be defined<br />
by the process, if the process<br />
is the principle you do not yet<br />
know and for which you are<br />
searching?” That is exactly the<br />
difficulty. In this respect, one might exclaim, looking back at the<br />
earlier calculus, “Ah, training wheels!”<br />
To accomplish the fullfillment of this method, Gauss<br />
generalized analysis for the first time. He took into consideration,<br />
the arc of the lemniscate which was not visible on the geometrical<br />
lemniscate: a ‘complex’ one. 43 Gauss, knowing the crime which<br />
Euler perpetrated in this regard, wrote that, by the neglect of<br />
imaginary magnitudes, the field of analysis “forfeits enormously<br />
43 Gauss never breathed a word about how he incorporated complex<br />
numbers into his analysis of higher functions, such as the lemniscate,<br />
except to his collaborator Bessel in 1811.[see letter in this<br />
issue]<br />
The Calling of Elliptical Functions<br />
Kirsch<br />
“On the lemniscate we have found out the most elegant<br />
things exceeding all expectations and that by methods<br />
which open up to us a whole new field ahead.”<br />
– Gauss 1798<br />
in beauty and roundness and<br />
in a moment all truths, which<br />
otherwise would be universally<br />
valid, are necessarily yoked to<br />
the most cumbersome limitations.”<br />
[emphasis added] 44<br />
44 This lack of universality arising as a consequence of dismissing<br />
‘imaginary’ values, is not limited to higher analysis. Gauss demonstrates<br />
two years later in his 1799 doctoral dissertation, that equations<br />
have imaginary roots, and likewise, that no general theorem<br />
can be stated about algebraic magnitudes, without their physical<br />
significance understood. This statement is also reflected in one who<br />
looks back upon the study of quadratic residues from the standpoint<br />
of biquadratic residues;what may seem as a paradox, such as -1 being<br />
a quadratic residue of all prime numbers of the form 4n+1 and<br />
not 4n+3, is clear as day to one who incorporates ‘imaginary’ numbers<br />
into the field of arithmetic, and contemplates the geometry of<br />
the complex modulus. http://www.wlym.com/~animations/ceres/<br />

So this was true indeed for the higher functions of the<br />
4th degree. Without this, their nature, and a new field, was not<br />
possible.<br />
Gauss examined the quotient of periodic functions from<br />
this standpoint and determined which values of the periodic functions<br />
make the numerator equal to zero, giving a value of zero for<br />
the elliptical function , and which values of the functions make<br />
the value of zero for the denominator, giving a value of infinity<br />
for the elliptical function.<br />
Without expressing the sine of a real arc plus an ‘imaginary’<br />
arc, the infinty points were not representable, indeed they<br />
could not be found; nor was the characteristic that the elliptical<br />
function is found to be periodic in two different ways. 45<br />
Once Gauss obtained the knowledge of the zero and<br />
infinity values of the of the elliptical function, he could then<br />
(employing some of his earlier inductive researches related to<br />
Lagranges algebraic method of inversion 46 ) represent them, first,<br />
by means of a quotient of infinite products, and, subsequently,<br />
by a quotient of power series, leading to a basis for investigating<br />
further into the nature of the lemniscatic function. 47 For example,<br />
Gauss finds that the logarithm of the numerical value he approxi-<br />
mates for the denominator is equal to π<br />
2 , which he says “is most<br />
remarkable, and a proof of which promises the most serious increase<br />
in analysis” (See Figure 1)<br />

The value of the angle which produces<br />
a given sine on a circle, is ambiguous<br />

y = xx<br />
√<br />
y = x<br />

By this, Gauss discovered a whole<br />
new set of relations for the numerator and<br />
denominator of the sine of the lemniscate,<br />
relating the arcs of the lemniscate, the circle,<br />
and the exponential functions. Using<br />
this, he continued to investigate the nature<br />
of the lemniscatic function as expressable<br />
through the infinity and zero points, but in<br />
ways which revealed deeper truths.<br />
Applying this new found relation,<br />
he investigated which values of the sine of<br />
the circle make the sine of the lemniscate<br />
equal to zero, and which make it equal to<br />
infinity, representing the lemniscate now by<br />
a quotient of infinite products whose variables<br />
were sines of the circle; later on, he<br />
converted this to a trigonometric series of<br />
multiple angles of circular sines.<br />
About the implications of this, he<br />
writes of this in late July 1798 in his day<br />
book: “On the lemniscate we have found<br />
out the most elegant things exceeding all expectations<br />
and that by methods which open<br />
up to us a whole new field ahead.”<br />
What was involved with this, was his study of the interelated<br />
properties of the numerator and denominator themselves. 48<br />
A Priest’s Calling<br />
Gauss investigated the domain in which the nature of the<br />
process generating elliptical functions exists. He investigated the<br />
characteristics which uniquely define elliptical functions. However,<br />
Gauss never made clear in his lifetime how he conceptualized<br />
the principle involved in these higher functions, and thereby,<br />
did not bring their potential fully into access for use by the human<br />
mind in conceptualizing the universe, and its processes.<br />
Bernhard Riemann, who like Kepler and Leibniz before<br />
him, had been in training to be a priest, inverts the problem altogether,<br />
defining ontologically what Gauss never stated.<br />
In Riemann’s lectures on Elliptical Functions, he begins<br />
with the characteristic that elliptical functions are doubly peri-<br />
48 This study of the numerator and denominator of the quotient<br />
expression of the elliptical function led to various paths. In 1799,<br />
Gauss’s first entries about his use of the arithmetic-geometric mean<br />
arise out of this research of the relations between the numerator and<br />
denominator of the elliptical function. Also, the development of his<br />
study of the numerator and denominator of the elliptical function<br />
becomes the basis for Gauss’s 4th proof of quadratic reciprocity. Jacobi,<br />
in his own studies of elliptical functions, references this paper<br />
by Gauss, when employing the same series, which he called the Theta<br />
Function. Later in Riemann’s lectures on elliptical functions, he<br />
discusses the Theta Function, seen here in a unique way in Gauss’s<br />
notebooks, as one of many expressions for elliptical functions.<br />

odic. From this fact, he then derives what the consequent characteristics<br />
would have to be, representing the zero and infinity<br />
points on a complex plane tiled with parallograms, whose sides<br />
represent the two periods which were originally set forth. From<br />
these characteristics alone, the total of all the possible values<br />
of the function to which a single parallelogram on the complex<br />
plane corresponds, is found to be equivalent to an elliptical<br />
integral. Thus, the elliptical integral is shown to be derived<br />
simply from the double periodicity.<br />
He then shows that since for doubly periodic functions<br />
of the second order, there are two values of the differential<br />
of the elliptical integral for every value of the inverse<br />
function, therefore, in order to conceptualize this inverse<br />
function, the two values have to be made distinguishable<br />
and unique. To achieve this, Riemann imagines two separate<br />
sheets, one for each value, and once more employs the<br />
characteristic zero and infinity points, but, this time, as discontinuities<br />
of the inverse function, to reunite the sheets in<br />
such a way as to obtain a connected surface, where one can<br />
traverse the whole range of possible values of the function<br />
continuously. However, the concept of the way in which<br />
these sheets are connected, representing the different values<br />
of the function, is not a concept which allows itself to be visually<br />
represented in sense-perceptible, three-dimensional space;<br />
this defines the nature of this class of higher transcendentals, to<br />
which the lemniscate and all of its related functions belong as<br />
special cases, as existing in such a domain, outside of sense perceptible<br />
physical space, conceivable in the intellect alone. 49<br />
The Calling of Elliptical Functions<br />
Kirsch<br />
The doubly-periodic function, from Bernhard Riemann’s<br />
lectures on Elliptical Functions<br />
49 It is unclear if Gauss had come to this conception but simply<br />
failed to present it. Two years after Gauss’s introduction of complex<br />
magnitudes into the study of higher transcendental functions, he<br />
demonstrates complex functions as a multiply connected geometry<br />
of two dimensions, in his 1799 Fundamental Theorem of Algebra.<br />
In letter to Bessel in 1811, Gauss writes of a proof for path independence<br />
for integration in the complex plane, that this path independence<br />
holds as long as integration is not through zero points, and<br />
Thus, as Cusa defined the characteristic of Notother,<br />
which all true principles in the universe share, their<br />
nature is that they, like the definition defining everything<br />
as being not other than the defined, define themselves.<br />
So, man is freed from the domain of the shadows,<br />
depending on predicates to express curves. Rather,<br />
the process which generates the sense perceptible curve is<br />
conceived in the mind; a concept of the substance so clear<br />
that, by the interconnected leaves of the Riemann surface,<br />
every value, every predicate is defined, as a result of the<br />
action of the substance itself.<br />
From the standpoint of this conception of elliptical<br />
functions---realizing that these are not sense perceptible<br />
curves, but have their nature and are derived from<br />
the characteristic of double periodicity---it is then clear<br />
that the former method of dealing with geometric curves,<br />
which for the most part looked at the characteristics of the<br />
effects of the process, was entirely inferior.<br />
Looking back from Riemann’s conceptual discovery,<br />
it becomes clear that with the correct understanding of higher<br />
physical functions, all of sense perceptible geometry exists as a<br />
special case, a projection of some higher function which can be<br />
conceptualized but not sense perceptibly represented.<br />
Branch Cuts, from Riemann’s lectures on Elliptical Functions<br />
Ah! But the question remains:<br />
If the catenary was the necessary physical process which<br />
defined the lower geometric transcendentals ontologically, and<br />
the multiply-connected Riemann surface is the concept which defines<br />
the geometric lemniscate, to what physical process does this<br />
concept correspond?<br />
that integrating through infinity points leads to multiple values of the<br />
function. Five years later, in 1816, in his third proof of the Fundamental<br />
Theorem of Algebra, he again discusses integration of areas<br />
on a plane, and makes an almost identical point that he earlier made<br />
to Bessel concerning the ambiguity of infinity points, with respect to<br />
values of an integral.<br />

Appendix: Imaginary Arcs<br />
In 1839, C. G. J. Jacobi read a paper at the Berlin Academy<br />
of Sciences devoted to the use of complex magnitudes in<br />
arithmetic. As introduction, he said this:<br />
“Gauss, in his investigations of biquadratic<br />
residues, introduced the complex numbers of the form<br />
a + b √ −1 as moduli or divisors... But, however simple<br />
such an introduction of complex numbers as moduli<br />
may now seem, it belongs nonetheless to the most<br />
profound notions of science; indeed, I don’t believe<br />
that arithmetic alone led the way to such concealed<br />
notions, but rather that it was derived from the study<br />
of elliptical transcendentals, and indeed the particular<br />
type that are given by the rectification of the arcs of<br />
the lemniscate... [J]ust as the arcs of the circle can be<br />
divided into n parts through the solution of an equation<br />
of the nth degree, the arcs of the lemniscate can<br />
likewise be divided into a + b √ −1 by the solution of<br />
an equation of degree aa + bb .”<br />
Jacobi was on to something, but he did not have the insight<br />
of Bernhard Riemann, or his teacher Carl Gauss. How did<br />
Gauss find the poles of the lemniscate function? Nowhere on its<br />
arc, does the lemniscate attain an infinite radius, although those<br />
infinite radii are represented in the denominator of the quotient<br />
Gauss has in his notebooks. Soon after this entry, Gauss demonstrates<br />
more of how he constructed a notion of functions:<br />
Here, we see Gauss determining the lemniscatic sine of<br />
an arc t plus an imaginary arc u √ −1 . How long is an imaginary<br />
arc? Use your imagination! Up until Gauss’s time, the predominant<br />
word on complex magnitudes was that, though they are impossible,<br />
and therefore imaginary, we need to use them to make<br />
the math come out alright. But, don’t go around thinking that<br />
they are actually real – we mathematicians can just make up anything<br />
we want, so our systems work out.<br />
Gauss thought that idea was not just perverted and lazy,<br />
but downright damaging to the progress of human science. In<br />
1799, he blasted the academics on this point, and showed that<br />
imaginary magnitudes were, in fact, more real than so-called real<br />
magnitudes. Gauss represented those complex magnitudes on a<br />
surface, where one direction was an increase in the real part of<br />
the number, and the perpendicular direction was an increase in the<br />
imaginary part of the number. So, an arc of a+bi must have two<br />
perpendicular components – but that doesn’t make any sense.<br />

First, let us see how this imaginary arc will represent<br />
itself through our sinlem equation. Using Gauss’s series approximation<br />
for the sinlem, let us see what happens when we make the<br />
arc imaginary.<br />
sinlem iφ = iφ − i 1<br />
10 φ5 + i 1<br />
120 φ9 − i 11<br />
15600 φ13 + ···<br />
= i(φ − 1<br />

120 φ9 − 11<br />
15600 φ13 + ···)<br />
= i sinlem φ<br />
How about for the coslem?<br />

2 φ4 + 3<br />
10 φ6 + 7<br />
40 φ8 + ··· =?<br />
Well, we know how long the coslem is in terms of the<br />
sinlem, so,<br />
�<br />
1 − (sinlem iφ)<br />
coslem iφ =<br />

1+(sinlem iφ) 2<br />

1+(sinlem φ)<br />

2<br />
1 − (sinlem φ) 2<br />
This should seem to not quite correspond to observed<br />
physics. While the physical lemniscate has only real arcs, our<br />
math equations are perfectly happy with imaginary arcs. But,<br />
where are they? One gets the sneaking suspicion, that when we<br />
answer this question, we will no longer be looking at a lemniscate<br />
curve.<br />
Now, let us force the addition formula to cough up some<br />
answers about this lemniscate function. First, we have the regular<br />
addition formula:<br />
(sl a)(cl b)+(sl b)(cl a)<br />
sinlem (a + b) =<br />
1 − (sl a)(sl b)(cl a)(cl b)<br />
Let us smoothly introduce our “imaginary arc” which, using the<br />
relations we just found,<br />
Now, our lemniscatic sine of a complex arc is expressed<br />
as the lemniscatic sines and cosines of purely real arcs. Let’s put<br />
in some values, to see what happens. 1<br />
We know the minimum and maximum values of the lem-<br />

niscatic sine and cosine of real arcs. If Π represents one half of an<br />
arc (or one lobe), then we can calculate several values. Thus, at<br />
the origin, the sinlem is zero and the coslem is 1. At an arc equal<br />
to one half Π, the sinlem is one, but the coslem is 0. At an arc<br />
of Π, the sinlem again equals zero, but the coslem has continued<br />
to the other side, to equal –1. At three-halves Π, the sinlem has<br />
passed over to the other side, and equals –1, but the coslem has<br />
returned to the center, and equals zero. Finally, at two Π, the<br />
sinlem is again zero, while the coslem is one.<br />
Now, we can see what kinds of values our “imaginary<br />
arcs” formula will give us. Let’s set u equal to one half Π, and let<br />
t cycle through our extreme points:<br />
for t = 0<br />
for t = one half Π<br />
for t = Π<br />
for t = three halves Π<br />
for t = 2Π<br />
0+i · 1 · 0 · 1<br />
1 − i · 0 · 1 · 1 =0<br />
1+i · 0 · 0 · 1<br />

0 − i ·−1 ·−1 · 0<br />
0+i · 1 · 0 · 1<br />
1 − i · 0 · 1 · 1 =0<br />
This is getting interesting. We have found some infinite<br />
lemniscatic sines! The lemniscatic sine for t = Π is a bit ambiguous,<br />
but that is OK, since we are just experimenting. Here is a<br />
table, with the values of sinlem for all values of u and t between<br />
zero and 2Π:<br />

The industrious reader will recognize that, if this table is<br />
continued to higher angles than 2 Π, it will simply repeat, in both<br />
the t and the u directions. Gauss recognized that, since the characteristics<br />
of repeating is different for the two directions, what<br />
we have here is a function that is doubly–periodic. It has two<br />
periods: one real, the other “imaginary.”<br />
One final step we can take, imagining what Gauss must<br />
have thought, a well-behaved function must be smooth everywhere,<br />
with the only exceptions at its poles. Imagine a sphere<br />
with infinite radius. Imagine that on that sphere is a set of perpendicular<br />
lines, one representing the growth of t, the other repre-<br />

senting the growth of u. Let a surface of varying height be placed<br />
upon this sphere, whose heights correspond with those values of<br />
the lemniscatic sine in our table. What would this look like?<br />
Where is the lemniscate, now? Perhaps it is only an effect<br />
of a higher, unseen function!<br />

Science in its Essence:<br />
On the Subject of ‘<strong>Insight</strong>’<br />
Lyndon H. LaRouche, Jr.<br />
This article first appeared in the May 9, 2008 issue of Executive<br />
Intelligence Review<br />
In my Sir Cedric Cesspool’s Empire, 1 I emphasized the<br />
importance of the concept of “insight” as key for, among other<br />
things, understanding the mechanisms of evil which characterized<br />
the most notable writings of the leading Fabian Society figure<br />
H.G. Wells. Here, I return to that notion of insight for conceptualizing<br />
the root-causes of the present plunge of world civilization,<br />
into the prospect of an immediate new dark age of mankind,<br />
a prospect caused by the role of the same standpoint of Wells in<br />
his threatening the planet as a whole, with what has now become<br />
its currently accelerating plunge toward an abyss.<br />
In real life, one never really knows what has<br />
been done, until one knows not only why and how it<br />
was done, but is capable of replicating the formation<br />
of the concept.<br />
As I have indicated within written and oral reports published<br />
earlier: looking back from today, the most crucial<br />
event in my life, has been my surefooted rejection of the<br />
concept of Euclidean geometry on the first day of my encounter<br />
with it in my secondary classroom. The most crucial implication<br />
of that for my later life, has been, that, in rejecting Euclidean geometry<br />
as intrinsically incompetent, as I did that day, I had actually<br />
made a decision which was to shape the essential features of<br />
my life over the seventy years which have followed that event.<br />
To repeat what I have said repeatedly on the subject of<br />
that event, over the intervening years, the following should be<br />
noted as an entry-point into the discussion to follow here.<br />
My fascination with the Boston, Massachusetts Charlestown<br />
Navy Yard, had been centered in the ongoing construction-work<br />
there. This had forced my attention to the fact of the<br />
challenge of understanding the geometric principle of construction<br />
through which the ratio of mass and weight of supporting<br />
structures to the support of the total structure, is ordered. This<br />
repeated experience, on both my several relevant visits there, and<br />
my haunting possession of the fact of that experience, had already<br />
established the meaning of “geometry,” as physical geometry, for<br />
me, that already prior to my first encounter with secondary school<br />
geometry. 2<br />
The continuing importance of my flat rejection of socalled<br />
Euclidean geometry at first classroom encounter with it, is<br />
typified by considering the way in which this reverberating experience<br />
led, a decade and more later, to my flat rejection of the<br />
sophistry of Professor Norbert Wiener’s presentation of so-called<br />
“information theory,” of the still wilder insanity of John von Neumann’s<br />
notions of “economics,” and von Neumann’s matching,<br />
pervert’s view of the principle of the human mind. These latter<br />
goads, and related experiences, prompted me, in 1953, to discover<br />
and adopt the appropriate consequence of Leibniz’s work,<br />
as the standpoint of Bernhard Riemann’s 1854 habilitation dissertation.<br />
In that light, this adolescent experience, with its outcome,<br />
is the best illustration from my experience of the proper technical<br />
meaning of the term “insight.” 3 In fact, it was an integral feature<br />
of the process which had led me, during adolescence, to adoption<br />
of the work of Gottfried Leibniz as the chief reference-point of<br />
my intellectual life, then, and, implicitly, to the present day.<br />
From that point in my youth, onwards, the chief philosophical<br />
reference-points in my intellectual development, were<br />
wrestling against the sophistry of Immanuel Kant’s series of “Critiques,”<br />
and the systemic sophistry of both Aristotle and his follower<br />
Euclid. It was against that background—those rejections,<br />
which had been fully established already for me during the course<br />
of my adolescence, that I came to recognize, and to rely upon the<br />
concept of insight per se: <strong>Insight</strong> as being the Platonic domain of<br />
hypothesizing the higher hypothesis, a concept of the nature of<br />
the human species and its individual member, which is central to<br />
all of the discoveries of principle by Plato.<br />

2 This development was associated, during that same period of<br />
my life, with my father’s principal intention in selecting those visits,<br />
the ritual tour of the U.S.S. Constitution; my own attention was<br />
focused on the mysteries of the construction in other parts of that<br />
yard.<br />

1. Man as Man, or Beast?<br />
The quality of insight, as I define it, again, here,<br />
is a specific potentiality which is fairly defined<br />
as being unique to all those individual human<br />
beings who are not victims of relevant physical or psychological<br />
damage.<br />
The present definition of human, as distinct<br />
from beasts, is the specific power of the human species<br />
to alter its behavior, as a species, to the effect that the<br />
potential relative population-density of the members<br />
of a culture is increased willfully, as this is illustrated<br />
not only by a human culture’s ability to increase its<br />
potential relative population-density willfully, but by<br />
the manifest transmission of such specific qualitative<br />
changes from one, to other members of the human species,<br />
as, for example, through stimulation of discovery<br />
of a physical principle by individuals presented with<br />
the appropriate intellectual stimulus.<br />
This quality is demonstrated, crucially, by the<br />
willful increase of the relative population-density of<br />
the human species, as expressed in the quality of antientropic<br />
increase of the mass of the Earth’s Noösphere,<br />
that relative, functionally, to the specific masses of the<br />
Biosphere and the mass of matter originally generated as part of<br />
the abiotic domain.<br />
Thus, there is no species of ape, or other beast, which is<br />
capable of meeting the standard of this test.<br />
On this account, there is only one human race, and no<br />
essential human differences in species, or variety, within the<br />
ranks of humanity so defined. 4 This functional distinction in the<br />
potentials of human behavior, whether expressed by individuals,<br />
or by societies as a whole, is properly approached for examination<br />
from the vantage-point established by Plato, both respecting<br />
Plato’s refined definition of the concept of hypothesis, and the<br />
systemically related subject of the quality of the individual human<br />
soul, as that subject was treated by Plato and Plato’s follower<br />
Moses Mendelssohn. 5<br />
4 Any deviation from that rule is “racism, per se,” which is, in<br />
itself, the expression of an impulse tantamount, under natural law, to<br />
crimes against humanity.<br />
5 I.e., both Plato’s Phaedo and the treatment of Phaedo by<br />

LaRouche<br />
Bernhard Riemann (1826-1866)<br />
In general, the Classical term hypothesis, when employed<br />
in any approximation of a meaningful, Platonic way, is<br />
already a reflection of specifically human potential for creativity.<br />
The simplest expression of that distinction is the difference<br />
between reason and Sophistry. For the purposes of our discussion<br />
here, Sophistry is typified by the reductionist method, opposed to<br />
reason, which was shared among Aristotle, Euclid, and the hoaxster<br />
Claudius Ptolemy, as typical of the Aristotelean form of the<br />
method of lying called “Sophistry,” or, in current argot, “spin.”<br />
The typical expression of corruption of the human mind<br />
in contemporary, globally extended European culture, is Anglo-<br />
Dutch Liberalism, otherwise known as the legacy of the New<br />
Venice faction of Paolo Sarpi. The extremely degenerate expressions<br />
of Liberalism (e.g., empiricism) today, are extreme expressions<br />
of Liberalism’s intellectual degeneracy such as positivism<br />
Mendelssohn. This is also the method of Nicholas of Cusa, as in De<br />
Docta Ignorantia, his follower Leonardo da Vinci, Johannes Kepler,<br />
Pierre de Fermat, Gottfried Leibniz, and Bernhard Riemann.<br />
Δυναμις Vol. 3 No. 3 December 2008<br />

and existentialism. 6<br />
Therefore, we shall proceed with our exposition here by<br />
taking up the case of Aristotle’s follower Euclid, as in the case of<br />
the work titled Euclid’s Elements.<br />
Minds Blinded by Sight<br />
The Aristotelean form of Sophistry represented by the<br />
Euclid of Euclid’s Elements, is premised upon so-called a-priori<br />
presumptions, assumptions which are associated with reliance<br />
upon the believed absurdity that “seeing is believing.”<br />
For example, it would be impossible to discover the universal<br />
principle of gravitation, as characteristic of the organization<br />
of the Solar System, except by relying, as Johannes Kepler<br />
did, upon the clear evidence of a systemic contradiction between<br />
the Solar System viewed from the standpoint of an assumed paradigm<br />
of sight, rather than the fruitfully paradoxical solution provided<br />
by contrasting the characteristic of hearing, as Johannes<br />
Kepler did, with the characteristic, linear presumption usually associated<br />
with a naive notion of the characteristic of sight. 7<br />
The entirety of the purely arbitrary presumptions underlying<br />
Euclid’s Elements, was located in a naive presumption<br />
respecting the assumed ontological elementarity of the characteristic<br />
of vision.<br />
Thus, true insight sees vision as such as representing the<br />
primitive level, sees that one’s opinions on this level, are products<br />
of a foolish belief in the reality of simple sense-experience.<br />
The lowest level of actual human intelligence, the level of actual<br />
insight, is the recognition of the fact that one’s opinions respecting<br />
sight alone, are being formed in the grip of a kind of form<br />
of mass-insanity such as “sense-certainty,” which is to be recognized<br />
as a mind blinded, thus, by blind faith in sight.<br />
For matters of science, and also history, naive seeing as<br />
such must be superseded by insight. 8<br />
6 Typically, mathematical formulations, such as mere statistics,<br />
are substituted for actual physical principles, and even for simple<br />
truth.<br />
7 Kepler’s reflection on the apparent role of the series of Platonic<br />
solids in locating the organization of the planetary orbits, led<br />
him, by aid of reflections on the preceding work of Nicholas of Cusa,<br />
Luca Pacioli, and Leonardo da Vinci, to recognize the composition<br />
of those Solar bodies then known to him as being an harmonic ordering.<br />
It was this recognition that led Kepler to his principled discovery,<br />
through recognition of the paradoxical juxtaposition of the<br />
assumptions of sight and the assumptions of harmonically ordered<br />
hearing.<br />
8 As in the distinction of Max Planck’s actual discovery from<br />
that positivists’ perversion (e.g., Ernst Mach, et al.) known as “quantum<br />
mechanics.”<br />
On the Subject of ‘<strong>Insight</strong>’<br />
LaRouche<br />
Kepler’s discovery of the principle of general gravitation,<br />
provides a typical kind of crucial proof of the fallacy of<br />
sense-certainty. In his Harmony of the <strong>World</strong>, the discovery of<br />
general gravitation within the Solar System required the juxtaposition<br />
of two notions of senses, those of sight and hearing (i.e.,<br />
harmony), for the derivation of a general principle of gravitation<br />
among the planets. This leads to the recognition that our powers<br />
of sense-perception are to be regarded as the natural experimental<br />
instruments which “come in the box of accessories”: when the<br />
infant is delivered from “the manufacturer.”<br />
A similar insight into the fallacy of “sense-certainty”<br />
was expressed by the ancient Pythagoreans and Plato, as this was<br />
typified then in a crucial way by the construction of the doubling<br />
of the cube by Plato’s friend from Italy, the Pythagorean Archytas.<br />
Similarly, the significance of Eratosthenes’ praising that<br />
construction, was shown afresh through Europe’s Eighteenth-<br />
Century conflict between the work of Gottfried Leibniz and the<br />
Anglo-Dutch Liberals (a.k.a. empiricists) Voltaire, Abraham de<br />
Moivre, D’Alembert, Leonhard Euler, and Euler’s dupe, Joseph<br />
Lagrange. 9 The modern history of that conflict begins with the<br />
Eighteenth-Century algebra of Ferro, Cardan, Ferrari, and Tartaglia,<br />
on the subject of quadratic, cubic, and biquadratic geometries,<br />
and continues through, and beyond, the work of Carl F.<br />
Gauss in such matters as the evolution of his treatment of his<br />
Fundamental Theorem of Algebra and related matters.<br />
Gauss’s Personal Situation<br />
Carl Gauss suffered the misfortune of having come to<br />
maturity in the aftermath of the French Revolution, a time which<br />
Friedrich Schiller identified as expressing a lost, great moment<br />
of opportunity in history (the American Revolution and the great<br />
work of Abraham Kästner, Gotthold Lessing, Moses Mendelssohn,<br />
Gaspard Monge, Lazare Carnot, et al. as a moment which had<br />
fallen prey to “a little people.” Thus, although Gauss’s achievements<br />
themselves were to be essentially a continuation of the<br />
legacy of Cusa, Leonardo, Kepler, Fermat, and Leibniz, Gauss’s<br />
professional career depended upon his avoiding the appearance<br />
of support for all things which might suggest indifference to the<br />
alleged genius of the hoaxster Galileo, Sir Isaac Newton, and of<br />
such Eighteenth-Century enemies of Leibniz and Leibniz’s follower<br />
Abraham Kästner as Voltaire, de Moivre, D’Alembert, Euler,<br />
Lagrange, and their Nineteenth-Century successors such as<br />
Laplace, Cauchy, Clausius, Grassmann, and Kelvin.<br />
Thus, once more, the early Nineteenth Century had<br />
brought on a period in which the minds of most were blinded by<br />
9 Lagrange, in the last years of his life, edified the tyrant Napoleon<br />
Bonaparte, an effort used by Napoleon to disperse the leaders of<br />
the Ecole Polytechnique into technical duties in the tyrant’s military<br />
service. It was Laplace and Cauchy who destroyed the educational<br />
program of the Ecole, on orders from London.<br />

sight.<br />
Thus, when I first introduced the LYM’s current “basement<br />
team” to the challenge of their present work (presently nearing<br />
completion) on the work of Gauss, I forewarned them, that,<br />
whereas Gauss’s work is brilliant, and his post facto account of<br />
the discoveries plausible; such was the nature of his time, that his<br />
actual method of discovery was tucked, as in the case of his personal<br />
preference for non-Euclidean geometry, behind a protective<br />
screen of intellectual camouflage.<br />
The implied duty laid upon him, or his successors, on<br />
account of that carefully crafted, protective screen, included the<br />
complementary obligation to uncover what lay, awaiting today’s<br />
attention, behind the camouflage imposed by those hoaxsters who<br />
represented the reputed embodiment of the alien, Newtonian tyrant.<br />
However, today, the present result of adopting that implied<br />
mission, is, that, to the degree Gauss’s discoveries are now being<br />
presented as finished reports from the standpoint of Bernhard Ri-<br />

Carl Friedrich Gauss (1777-1855)<br />
emann’s frankness in this matter, the results, thus far, are, increasingly,<br />
most agreeable.<br />
Thus, the true genius of Carl Gauss could be recognized<br />
by students today, only when the fact is considered, that much of<br />
what Bernhard Riemann said and wrote, was indebted to what<br />
Gauss, in his adult years, rarely dared to say publicly. Therefore,<br />
to really understand Gauss, it is necessary to know Riemann, and<br />
then to see how much of Riemann’s wonderful work, his habilitation<br />
dissertation and beyond, had been made possible by what<br />
Riemann recognized as having been lurking within the shadows<br />
of what Gauss had permitted himself to say.<br />
Gauss’s repeated treatments of the subject of his doctoral<br />
dissertation, on the subject of The Fundamental Theorem<br />
of Algebra (as complemented by the related paper on the law of<br />
quadratic reciprocity), are to be recognized as a recurring theme<br />
in much of the span of Riemann’s work. 10<br />

back from the account of Gauss’s role as such, to the<br />
ontological implications of insight per se—the point of<br />
reference, the ontological standpoint, at which Gauss’s published<br />
accounts of his discoveries, are, for reasons noted above, often<br />
met at their relatively weakest expression. Gauss’s recurring,<br />
fresh treatment of the subject of his first three statements of what<br />
he would come to call his “Fundamental Theorem of Algebra,”<br />
and the intimately related, higher subject of “the law of quadratic<br />
reciprocity,” is typical.<br />
Nonetheless, Gauss’s intention, however bounded by<br />
the ugly peer-review pressures of his time and place as a young<br />
adult, onward, is nevertheless to be seen as persistent in his effort<br />
to provide his more sensible readers crucial evidence leading<br />
them, hopefully, toward the relevant conclusions which Gauss<br />
dares not state explicitly. 11 Once Riemann’s 1854 habilitation dissertation<br />
and his treatment of Abelian functions are taken into<br />
account, and the preceding writings of Gauss viewed from this<br />
standpoint, the debated matter of Gauss’s ontological intention,<br />
contrary to D’Alembert, Leonhard Euler, and the crooked British<br />
imperial assets Laplace and Cauchy, et al., should be clear to any<br />
qualified student of such matters. 12<br />
Gauss’s treatments of the subject of the Fundamental<br />
uttered as a direct rebuttal of Euler’s 1760 publication on that subject<br />
and the closely related matter of the law of quadratic reciprocity. In<br />
all of his published work on this subject, the underlying theme which<br />
Gauss references, but does not state explicitly, is the Leibniz notion<br />
of the ontologically infinitesimal, a connection made implicitly<br />
clear in Gauss’s work.<br />

French intention of electing Lazare Carnot President of a French<br />
Republic was defeated by action of the relevant British occupation<br />
authority, the Duke of Wellington, sticking a wretched Bourbon on a<br />
London-controlled French throne. Under this British reign over occupied<br />
France, the scoundrels Laplace and Cauchy were installed to<br />
uproot the educational program of the Ecole Polytechnique’s Gaspard<br />
Monge. Monge was dumped, and his associate Lazare Carnot<br />
went to die as an exiled hero, in Magdeburg. The mental disease<br />
called positivism, thus grabbed control, but for a relatively few stubborn<br />
heroes, of the official French scientific intellect. Cauchy’s role<br />
as a hoaxster, and plagiarist of the work of Abel, was finally exposed<br />
by examining Cauchy’s post-mortem files. Carnot was a fellow<br />
member, with Alexander von Humboldt, of the Ecole.<br />

Theorem of Algebra and its crucial, correlated reflection of that<br />
“Theorem,” as reflected in what he defines as a “law of quadratic<br />
reciprocity,” point the alert student toward the ontological issue<br />
which he wishes to argue, but, considering the auspices, he dares<br />
not do that too explicitly. The often referenced parallel, related<br />
case of what is actually anti-Euclidean geometry, is to be considered<br />
in this light, as being a correlative of that view of the<br />
Fundamental Theorem.<br />
The relevant argument to that effect, is as follows.<br />
Once we acknowledge, as the Pythagoreans and Plato<br />
already knew, that the objects of sense-certainty are never better<br />
than shadows cast by an unsensed, but nonetheless efficient reality,<br />
and, when the same matter is then reviewed from the standpoint<br />
of Riemann’s work, the issues are much clearer.<br />
The crucial point, as I have repeatedly emphasized in<br />
earlier locations, is the fact that the enemy of Leibniz, of Gauss,<br />
of Riemann, et al., in science, has been the pack of hoaxsters<br />
typified by the Eighteenth-Century Liberals such as Antonio<br />
Conti, Voltaire, de Moivre, D’Alembert, Leonhard Euler, and<br />
Euler’s dupe Joseph Lagrange. With that British victory over<br />
France which Britain secured through, successively, the siege of<br />
the Bastille, the French Terror, Napoleon Bonaparte’s reign, and<br />
the British monarchy’s triumph at the Congress of Vienna, young<br />
Gauss had now entered the Nineteenth Century, entering a world<br />
in which official science was oppressed by the top-down enforcement<br />
of that moral, intellectual corruption known as the Liberalism<br />
of Euler and Euler’s followers.<br />
If we, then, take into account the specific issues of scientific<br />
method posed, still today, by that same Liberal political<br />
corruption, of the reigning official opinion in science of that time,<br />
and ours, too, we are enabled to distinguish what Gauss clearly<br />
intended, from what the same fear of reactions by powerful adversaries<br />
prevented him from stating clearly, as was the case in<br />
his suppression of reports of his own discoveries in anti-Euclidean<br />
geometry. To present this case, it is necessary to restate here<br />
the related point made in locations published by me earlier.<br />
The Roots of Science<br />
When we trace the history of European science from its<br />
roots, in Sphaerics, from the ancient maritime culture which settled<br />
Egyptian civilization (including that, notably, of Cyrenaica),<br />
we must recognize what can be competently termed “science” as<br />
being rooted essentially in the development of the navigational<br />
systems of the ancient, seafaring maritime cultures of the great<br />
periods of glaciation, rather than such silly, but popular academic<br />
myths as attempting to trace civilization from “riparian” cultures<br />
as such. It was the observation of both seemingly regular and<br />
anti-entropic cycles in the planetary-stellar system, which is the<br />
only supportable basis for the notion of “universal,” as that term<br />
could be properly employed for grounding the notion of science<br />
per se today.<br />
Δυναμις Vol. 3 No. 3 December 2008<br />

The case of the settlement<br />
of Sumer and its culture, from the<br />
sea, by a non-Semitic people’s<br />
sea-going, Indian Ocean culture’s<br />
colonizing of southerly Mesopotamia,<br />
is indicative. 13 In any case,<br />
the very idea of science would have<br />
no secured basis in knowledge unless<br />
very long spans of ocean-going<br />
maritime cultures were taken into<br />
account for crucially relevant features<br />
of ancient calendars.<br />
In short, the notion of<br />
universal, which does not exist as<br />
a functional conception in Liberalism,<br />
is the essence of any competent<br />
effort at developing actual scientific<br />
knowledge. Only long-ranging<br />
ancient maritime cultures could<br />
have been impelled to produce the<br />
elementary considerations underlying<br />
the Sphaerics from which all of<br />
competent strains in European, or<br />
other science has been derived. The<br />
idea of a universal physical principle,<br />
on which all competent science<br />
is premised, could not come into<br />
existence for mankind in any other<br />
way, unless we were to presume<br />
the source of this opinion to be,<br />
arbitrarily, colonists arriving from<br />
“outer space.” I emphasize, that the<br />
true concept of universal, does not<br />
actually exist as a scientific conception<br />
within the bounds of empiricism or its spin-offs.<br />
What we know with certainty, respecting contrary views<br />
on the possibility of the existence of a practice of science, is that<br />
the contrary views are all either implicitly “malthusian,” or are<br />
products of a type of culture, such as the typical “oligarchical<br />
model,” congruent with malthusianism. I emphasize, that all<br />
such latter types known to us generally now, belong to a category<br />
known to ancient through modern European cultures as “the oligarchical<br />
model,” a model to be recognized as being congruent<br />
with Aeschylus’ representation of the Satanic-like figure of that<br />
Delphic Olympian Zeus. This was the Zeus, who, in Aeschylus’<br />
13 Suspected to have been an offshoot of a maritime culture of<br />
the Dravidian, or closely related language-group. Herodotus indicates<br />
a kindred maritime-cultural origin for Ethiopia. So, Bal Gangadhar<br />
Tilak back-traced the origins of Sanskrit to a colonization,<br />
across land, from the north coast of Siberia, through mid-Asia, into<br />
Iran and northern India (Orion, and Arctic Home in the Vedas).<br />

of science (e.g., “fire”) from the<br />
minds of those mortal men and<br />
women such as Lycurgan Sparta’s<br />

It is to be emphasized now,<br />
as we contemplate the global wave<br />
of mass-starvation which has been<br />
caused by the spread of the massmurderous,<br />
neo-Malthusian model<br />
of that British lackey otherwise<br />
known as former Vice-President<br />

great crises of known civilizations<br />
have been the result of those same<br />
policies of practice which are fairly<br />
identified as pro-Satanic attempts<br />
to ban scientific knowledge and its<br />
practice from the great majority of<br />
the world’s human populations. 14<br />
Such has been the accelerating<br />
decline of the physical economy<br />
of the U.S.A., per capita and per<br />
square kilometer, since the terrible<br />
developments and aftermath of<br />
1968. 15<br />
The upshot of that line of<br />
inquiry, is that we exist within a<br />
stellar universe which is governed<br />
by what Albert Einstein, for example,<br />
emphasized as being universal<br />
physical principles of change.<br />
14 Former U.S. Vice-President Al Gore, a British agent against<br />
the U.S.A.’s American System of political-economy, who walks in<br />
the footsteps of the de facto traitor to the U.S.A., and sometime U.S.<br />
Vice-President Aaron Burr, is a typical advocate of the “oligarchical<br />
model.” President Andrew Jackson of “Trail of Tears” notoriety, had<br />
been an accomplice of Burr’s anti-U.S. conspiracy, and had served<br />
as U.S. President as a lackey and accomplice of Land-Bank swindler<br />
and later U.S. President Martin van Buren.<br />
15 It is not merely the actions of the trans-Atlantic “sixty-eighters”<br />
and the U.S. Richard Nixon Administration which have caused<br />
the pattern of accelerating physical decline of the economies of the<br />
Americas and Europe since 1968. Trends do not perpetuate themselves,<br />
except as the relevant trend takes life, as a form of “tradition,”<br />
within the culture of those who are shaping the policy-making<br />
proclivities of the society. To free the U.S.A., in particular, from the<br />
grip of forty years of self-destruction, we must free control over our<br />
society’s policy-shaping from the hands and minds of those who embody<br />
the “68ers” tradition.<br />

These principles are presented to us in this capacity,<br />
as they were to long-ranging ancient maritime cultures,<br />
presented so in their astronomical expression,<br />
as a combination of both ostensibly regular and antientropic<br />
universal physical principles of change. Some<br />
cycles, such as the equinoctial cycle, are long-ranging,<br />
and may appear to be fixed. However, contrary to the<br />
neo-Aristotelean fraudster Claudius Ptolemy, and to<br />
Clausius, Grassmann, and Kelvin, the universe is not,<br />
ontologically, a domain of cycles of repeatedly fixed<br />
no-change: the universe is essentially anti-entropic.<br />
In the latter case, that universe of change, the<br />
universe is finite, but anti-entropic, in the respect that<br />
nothing exists outside it. Thus, rather than the foolishness<br />
of a ignorant believer’s assumption of an Euclidean<br />
or Cartesian, limitless space, the universe is not Euclidean,<br />
nor Cartesian, but a dynamic system in the sense<br />
of dynamic employed by the ancient Pythagoreans and<br />
Plato, or such as Leibniz, Riemann, Max Planck, and<br />
Einstein, in modern science. This notion of a physically<br />
efficient universality which I have just presented here<br />
so, is, as Albert Einstein emphasized, indispensable for<br />
modern universal science; without this notion, no competent<br />
notion of the work of Kepler, Fermat, Leibniz,<br />
Gauss, or Riemann can be reached.<br />
This notion which I have just so emphasized, is<br />
crucial for understanding the great Nineteenth-Century<br />
crisis in science which Gauss and Riemann addressed.<br />
The interwoven conceptions of a “Fundamental Theorem<br />
of Algebra” and “law of quadratic reciprocity”<br />
in the work of Gauss, are typical of this. Riemann’s<br />
remedy for what is lacking in the work of Gauss, addresses<br />
precisely this conceptual problem, a problem<br />
which continues to underlie not only the ongoing essential<br />
work of all modern science, but the systemically<br />
dynamic form of social crisis menacing the very existence<br />
of world society today.<br />
Our Universe<br />
That aspect of the efficiently existing universe which is<br />
accessible to our sense-perceptual powers, is the passing footprints<br />
of those powers which generate such shadows themselves. As Albert<br />
Einstein made this point in his own fashion, it is through the<br />
relevant power of insight, like that of Kepler’s uniquely original<br />
discovery of universal gravitation, which is, manifestly, uniquely<br />
specific to the human species, that we are enabled to adduce the<br />
eternal motion of that great unseen entity which has left those<br />
footprints upon our heavens. Such is the implication of Riemannian<br />
dynamics, as also that of Leibniz before him.<br />
As emphasized here earlier, the fact that the organization<br />
of the Solar System is fairly regarded as in conformity with<br />
On the Subject of ‘<strong>Insight</strong>’<br />
LaRouche<br />
Cupola of Santa Maria del Fiore, in Florence, Italy<br />
Kepler’s harmonic approximation, as Albert Einstein emphasized<br />
the principle involved, defines a universe which is ontologically<br />
finite. That is to say, that principles, such as the principle of<br />
gravitation as discovered by Kepler, principles which envelop our<br />
universe, are discoverable, and provable, only through the kind<br />
of method of dynamics which Gottfried Leibniz revived from<br />
the earlier discoveries of the Pythagoreans and Plato. We owe<br />
comprehension of the implications of that fact, as Albert Einstein<br />
emphasized, chiefly to the work of Johannes Kepler and Bernhard<br />
Riemann. However, that discovery had already been made<br />
implicitly by Cardinal Nicholas of Cusa, in such among his works<br />
as the seminal De Docta Ignorantia, but it had also been known,<br />
earlier, by the Pythagoreans and Plato.<br />
To restate this same point: the principled form of ac-<br />
Δυναμις Vol. 3 No. 3 December 2008<br />
33
tion which is expressed to our senses as a predicate of universal<br />
principles, is the universal principle on which all manifest forms<br />
of apparently principled actions depend for their expression. The<br />
universe of experience is defined, thus, as Einstein defined it, as<br />
self-bounded. Thus, it is a finite universe in that sense, but without<br />
any external boundary but the principle of anti-entropic, creative<br />
powers associated with the notion of a Universal Creator.<br />
The human faculty upon which such higher-ranking<br />
knowledge of that higher, efficiently necessary existence depends,<br />
is the object of insight in the fullest sense of Plato’s presentation<br />
of that notion. Thus, all competent modern science depends upon<br />
the view of this matter by Nicholas of Cusa.<br />
To summarize that point: the notion of an ontologically<br />
existing universe, as opposed to some Euclidean or kindred sort<br />
of Sophist’s fantasy, depends upon the notion of universal lawfulness,<br />
as Einstein’s view of Kepler’s work illustrates the crucial<br />
point of all this present discussion.<br />
To illustrate that point, take the case of the history of the<br />
modern European discussion which led into Gauss’s first statement<br />
of what was to become known as his view of the challenge<br />
of the Fundamental Theorem of Algebra. Go back to the previously<br />
referenced, Sixteenth-Century treatment of the subject of<br />
the relations among quadratic, cubic, and biquadratic residues, as<br />
by Cardan et al.<br />
The ontological implications of this Sixteenth-Century<br />
treatment of those matters must be considered against the background<br />
of Archytas’ duplication of the cube. Against that historical<br />
background of Sphaerics, the principled nature of the systemic<br />
fallacy of the method employed by Cardan et al. should have<br />
been obvious. What should have been the obvious remedy for<br />
that had been supplied, during the Fifteenth Century by the work<br />
of Filippo Brunelleschi, 16 Nicholas of Cusa, and Luca Pacioli, as<br />
also by the surviving known fragments of the work of Leonardo<br />
da Vinci. In brief, the necessary approach would have been the<br />
same concept of physical geometry on which I had insisted during<br />
my adolescence, or, much more appropriately, Riemannian<br />
physical geometry, rather than the ivory-tower formalities of an<br />
implicitly pro-Euclidean algebra.<br />
In other words, when the empiricist followers of Descartes<br />
and Antonio Conti employed the fallacy of the hoaxsters de<br />
Moivre and D’Alembert, in crafting the hoax of so-called “imaginary<br />
numbers” for the fraudulent attack on Leibniz by themselves,<br />
Leonhard Euler, et al., they were not merely constructing<br />
a fraud against physical science. They were behaving as a-priorist<br />
incompetents in refusing to grasp the readily accessible, physicalgeometry<br />
implications of the uniqueness of Archytas’ method for<br />
constructing a process of duplication of the cube, rather than the<br />
intrinsically incompetent, Sophist method of Aristotle, Euclid,<br />
16 As in Brunelleschi’s employment of the catenary as a principle<br />
of physical geometry which had been the required principle of<br />
design for the construction of the cupola of Santa Maria del Fiore.<br />
On the Subject of ‘<strong>Insight</strong>’<br />
LaRouche<br />
and Claudius Ptolemy.<br />
Admittedly, this erroneous presumption reflected a crucial<br />
oversight which had been made by the Sixteenth-Century<br />
set of Cardan et al., prior to the experimentally crucial discovery<br />
of least action by Pierre de Fermat. However, the discoveries by<br />
Kepler and Fermat were an integral feature of both the uniquely<br />
original discovery of the calculus (ca. 1676) by Leibniz, but,<br />
more emphatically, Leibniz’s taking into account the crucial principle<br />
of Fermat in Leibniz’s own crafting, in collaboration with<br />
Jean Bernouilli, of the concept of a universal physical principle<br />
of least action.<br />
This “imaginary number” fraud by de Moivre,<br />
D’Alembert, Euler, et al., was not merely a reflection of their apparent<br />
ignorance of elementary principles of physical geometry<br />
known since no later than Archytas and Eratosthenes. It was to be<br />
seen as an echo of the “malthusian” oligarchical-model hoax expressed<br />
by the Olympian Zeus of Aeschylus’ Prometheus Trilogy.<br />
When that aspect of the matter is taken into account,<br />
the difficulty which threatened Carl Gauss in the matter of the<br />
Fundamental Theorem of Algebra, ought to become transparent.<br />
Gauss’s third statement of that case ought to have made it clear,<br />
retrospectively, to all modern mathematical physicists re-considering<br />
Gauss’s proof, once the publication of Riemann’s habilitation<br />
dissertation had made clear the essential issue lurking in the<br />
shadows of Gauss’s own argument.<br />
From the appearance of Riemann’s habilitation dissertation<br />
and his Theory of Abelian Functions, onward, the deeper<br />
implications of the history of modern science since Nicholas of<br />
Cusa’s De Docta Ignorantia should have been clear, as Albert<br />
Einstein located the root of competent modern physical science<br />
in those methods which Kepler had attributed to Cusa’s work, the<br />
work which, chiefly, founded competent forms of modern European<br />
science.<br />
Such is the nature of true insight.<br />

At the close of July 2007, the world as a whole entered<br />
a phase-shift into chronic hyperinflation, into what has<br />
been, ever since that date, a general breakdown-crisis of<br />
the present world system as a whole. Since that time, the entire<br />
world’s presently existing, post-August 1971 monetary-financial<br />
system, has been doomed to its extinction, in one way, or another.<br />
There are alternatives, but these mean abandoning what<br />
has become the 1971-2008 world monetary-financial system.<br />
It means putting the present system under a juridical system of<br />
reorganization-in-bankruptcy, and replacing it with an echo of<br />

The Individual in History<br />
As I have said repeatedly, of late, the history of mankind<br />
is not event-driven; it is man-driven. The most essential decisions<br />
which drive the actually crucial changes in the course of history<br />
have often been what was deemed impossible by conventional<br />
opinion-makers earlier. It is not what happened in yesterday’s<br />
usually fraudulent leading press reports which drives history;<br />
it is men or women of a special kind of influence, such as our<br />
Benjamin Franklin, or the great historian and dramatist Friedrich<br />
Schiller, who choose to lead nations in one direction or another.<br />
It is rarely a matter of choosing from among multiple choices<br />
on the table; the most momentous turns in history have been the<br />
changes, changes made by the initiative of a seemingly tiny minority,<br />
changes like the founding of our Constitutional republic<br />
which had seemed, in July 1776, to the world at large, not merely<br />
impossible, but an ill-fated conceit of a few.<br />
The greatest decisions in history are made by men or<br />
women, as individuals, decisions which have seemed virtually<br />
impossible to conventional institutions and public opinion even<br />
a relatively short time before. All great turns in history of that<br />
quality come as the unique innovation in thought and will by relatively<br />
rare individuals. So, President Abraham Lincoln saved our<br />
republic, virtually despite itself; so, the greatest poets and scientists<br />
did what no one else had dreamed before.<br />
The greatest of all such deeds occur in such times as those<br />
of which the great English Classical poet, Percy Bysshe Shelley<br />
wrote in his In Defence of Poetry. There are times when much<br />
of a people is overcome by a marvelous increase in the power of<br />
imparting and receiving profound and impassioned conceptions<br />
of man and nature, as by the inspiration of the then already deceased<br />
Friedrich Schiller in calling forth the great initiative of the<br />
German people led by Scharnhorst in organizing, according to the<br />
principle of strategy defined by Schiller’s studies of the religious<br />
wars in the Netherlands and the Thirty Years War, to accomplish<br />
the otherwise seemingly impossible defeat of the tyrant Napoleon<br />
Bonaparte in Russia and in that tyrant’s desperate effort to return<br />
to France to raise a new army and a new general war.<br />
So, a Genoese sea-captain working in the service of Portugal,<br />
the greatly talented and inspired Christopher Columbus,<br />
was led by his continuing study of the testament of the founder<br />
of modern science, Cardinal Nicholas of Cusa, one of the greatest<br />
geniuses of all modern history, to devise a plan for realizing Cusa’s<br />
program, for great strategic voyages across the great oceans,<br />
to rescue a corrupted European culture by extending its reach to<br />
distant lands. This was Cusa’s intention, as actually adopted, with<br />
full consciousness of that intention, by Columbus from about<br />
1480 onward, which created the Americas, and brought about<br />
that subsequent colonization of New England which gave birth to<br />
what became our United States.<br />
This was the object of the actual founding of our republic,<br />
the U.S.A., whose morality was defined, first, by the crucial<br />
On the Subject of ‘<strong>Insight</strong>’<br />
LaRouche<br />
Christopher Columbus (1451-1506)<br />
passage of a work denouncing the evil slaver John Locke, the passage,<br />
“the pursuit of happiness,” from Gottfried Leibniz’s New<br />
Essays on Human Understanding, which is the core principle<br />
of our Declaration of Independence and the root of the principle<br />
of moral law of our republic which is elaborated, as in the spirit<br />
of the Peace of Westphalia, as also reflected in the great Platonic<br />
and Christian principle of agape, in the Preamble of our Federal<br />
Constitution.<br />
Thus, the true history of mankind is only that which is<br />
defined by the actuality of the perfectly sovereign creative powers<br />
which can be expressed only by the individual creative personality.<br />
These are the same creative powers, unique to sovereign<br />
individual minds, which are expressed by uniquely great discoveries<br />

ackground, is that the chief source of the ugliest failures of<br />
humanity is a certain kind of popularized stupidity of the type<br />
demanded by the Olympian Zeus of Aeschylus’ Prometheus<br />
Bound, as demanded by the creature of the British Foreign Office’s<br />
Jeremy Bentham, Thomas Malthus, or as the lame-brained<br />
perversions uttered by that pathetic puppet known as the incumbent<br />
President of our U.S.A. Popular opinion, such as that induced<br />
by our presently, inherently corrupt and lying major news<br />
media, is the deadliest of the Trojan Horses inserted into the domains<br />
of mankind today.<br />
In that sense, the issue of the development of the creative<br />
powers of the individual young member of society is, in<br />
the final analysis, the most crucial political, and also moral issue<br />
of the existing cultures of this planet, most notably our presently<br />
dumbed-down, Boomer-ridden U.S.A. Our present educational<br />
systems have assisted greatly in making our people stupid enough<br />
to be influenced by the opinions uttered by the proverbial “paid<br />
prostitutes” of our presently popular “yellow” press.<br />
The Relevant Paradox<br />
The power of creativity, as I have presented the case<br />
summarily in the preceding chapters here, is, as I have already<br />
emphasized, not only a built-in natural potential of the human<br />
individual, a potential absent in all animal species; it is unique<br />
to all persons who are not victims of relevant damage to their<br />
potential range of human powers. In broad terms, therefore, every<br />
individual should be developed as a truly creative personality.<br />
As the case may be, as cows do not make for intelligent<br />
citizens, it is wrong to attempt to train people to become cows, as<br />
the latter has been done, in effect, to most of the human population<br />
in most known cultures to present date. The subject, therefore,<br />
is, once more, the case of the suppression of knowledge of<br />
“fire” by order of the archetypical Malthusian (or, present-day<br />
Malthusian and lying former Vice-President Al Gore). Only under<br />
artificial conditions such as those prescribed by Britain’s leading<br />
anti-humanist, the <strong>World</strong> Wildlife Fund’s Prince Philip, is the<br />
natural, human intellectual potential of the person suppressed in<br />
ways—pro-Malthusian ways—which turn children into the virtually<br />
half-witted cattle of today’s neo-Malthusian movements.<br />
Consider what caused the legendary Olympian Zeus to<br />
cook up this anti-human role of “environmentalism.” There are<br />
two, complementary motives.<br />
First, actually creative and brave people will not willingly<br />
submit to either a legendary Olympian Zeus, or a Prince<br />
Philip or Al Gore. Second, since mankind’s creativity is typically<br />
expressed through its realization as scientific and related progress<br />
in developing prevalent human conditions, the continuation of<br />
the progress which man’s true nature demands, “uses up natural<br />
resources” in ways which only the natural advances in the science-driven<br />
and related creative productive powers of mankind<br />
could remedy.<br />
On the Subject of ‘<strong>Insight</strong>’<br />
LaRouche<br />
On the latter account, of the Earth’s total mass, the portion<br />
corresponding of pre-biotic masses is shrinking as a percentile<br />
relative to the product of living processes, while the rate of<br />
increase of the portion of the mass generated by human activity is<br />
increasing, relative to both abiotic residues and residues of other<br />
kinds of living processes.<br />
Thus, to keep large populations sufficiently stupefied to<br />
be reigned over by the tyrannical likes of the Olympian Zeus, it<br />
is necessary (for the sake of that tyranny) to keep subject populations<br />
as stupid as possible, and, therefore, to prevent actual increases<br />
in the productive powers of human labor, or, even, as has<br />
been done in the U.S.A., and in western and central Europe since<br />
1989, to reverse previous economic progress absolutely. 18<br />
For that reason, nominal American citizens such as former<br />
Vice-President (and traitor) Aaron Burr and former Vice-<br />
President-turned-British-lackey Al Gore do not like honest patriots<br />
of our U.S.A. very much.<br />
However, on the opposite side of that matter, the potential<br />
for developing true scientific creativity, and also artistic creativity<br />
in the individual member of society, is there. It exists, and<br />
can be promoted, if we come to understand this subject-matter,<br />
and are willing to make its achievement the essential goal for the<br />
development of our future individual citizen.<br />
My own dedication to that mission is multifarious; but,<br />
my most essential, relevant skill is in the field of those expressions<br />
of physical-scientific creativity which are coincident with<br />
my special competence in the domain of physical economy. To<br />
this end, I have promoted an approach to the students’ replication<br />
of the development of the principal valid currents of physical science,<br />
ranging, explicitly, and most typically, from the Pythagoreans<br />
and Plato through Cusa, Leonardo, Kepler, Fermat, Leibniz,<br />
Gauss, the Monge-Carnot phase of the Ecole Polytechnique,<br />
Dirichlet, and Riemann. Those who work in relevant forms of<br />
teams, to relive the acts of discovery which are most relevant<br />
for re-experiencing first-hand knowledge of the most-relevant<br />
discoveries, can generally succeed in one significant degree or<br />
another.<br />
With great science and great Classical art, combined, we<br />
can generate among us new generations sharing the quality of<br />
temperament we should require for those generations of our new<br />
citizens. The benefit would be, not only skills, but the fostering of<br />
the truly creative powers of the human mind, upon which progress<br />
depends.<br />
Best of all, once one knows that expressed quality of<br />
potential in oneself, which distinguishes one from an ape, or brutalized<br />
slave, insight comes naturally, because it is natural, for as<br />
long as people are developed for what the human individual is,<br />
and is intended to become.<br />

Decomposition of Integral Algebraic<br />

Carl F. Gauss<br />
Δυναμις Vol. 3 No. 3 December 2008<br />
This, the third of Carl Gauss’s four proofs of the Fundamental<br />
Theorem of Algebra, appeared in 1816. Here, Gauss makes a rare inter-<br />
ventiaon for a physical basis of mathematics. It was translated by Mervyn<br />
Fansler, who offers this disclaimer: “Since my German is much further along<br />
than my Latin, this translation derives from a German translation of the<br />
original published by E. NE t t E in Ostwald’s Klassiker der exakten<br />
Wissenschaften, B. 14. The original Latin version, which appeared in the<br />
Commentationes recentiores... and is the version published in Gauss’s<br />
Gesammelte Werke, was consulted as a reference.<br />
After the previous treatise was already printed, continued<br />
meditations upon the same subject led me to a new proof<br />
of the theorem, which, similar to the preceding, is purely<br />
analytical, yet is based upon entirely different principles, and,<br />
with respect to simplicity, appears by far to be superior to the for-<br />
mer. To this third proof are the following pages now devoted.<br />

The factor r can evidently be canceled out of the de-<br />

by it. Finally, let r be a determined positive magnitude, which,<br />
though indeed arbitrary, should still exceed the highest of the<br />
magnitudes<br />

Theorem. Within the boundaries r = 0 and r = R, as<br />
well as ϕ = 0 and ϕ = 360°, there exists such values of the<br />
indeterminates r, ϕ, for which t = 0 and u = 0 at the same<br />
time.<br />

not true; it is evident that the value of t2 + u2 T 2 + U 2<br />

which thus acquires a finite, completely determined value. This<br />
value, which we will signify by Ω,<br />
must be obtained regardless<br />
of whether the integration is performed first with respect to ϕ and<br />
then with respect to r, or the inverse order. We have, however, the<br />
indefinite, if we consider r as a constant,<br />

constant is not added, if we presume that the integration begins<br />
at ϕ = 0, since for ϕ<br />

however, if either sin G = 0 and thus cos G = ±1 or g = 0, each<br />
sin G =0 of the factors will be identical, namely, = x∓ g. It thus holds<br />
true that the function X possesses a real divisor of the second or<br />
cos G = first ±1 degree, and since the same conclusion will again hold for the<br />
quotient, X is thus completely dissolvable into such factors.<br />

Although we have brought the task we had undertaken<br />
completely to an end with the preceding, still it would not be superfluous<br />
to add something further concerning the inferences of<br />
§ 2. By the assumption that t and u vanish at the same time for<br />
no values of the variables r, ϕ within the boundaries given there,<br />
we happen upon an inevitable contradiction, whereupon we have<br />
concluded the incorrectness of the assumption itself. This contradiction<br />
must therefore cease, if there is an actual value of r, ϕ<br />
for which t and u become = 0 at the same time. In order to further<br />
clarify this, we observe that for such values t<br />

mC √ will = 0 and<br />
thus y become infinite, so that it no longer is permitted to treat the<br />
double integral<br />
2<br />
�� ydrdϕ as an assignable magnitude. Given<br />
in general, if ξ, η , ζ signify the coordinates of spatial points, the<br />
integral �� ��<br />
ydrdϕ ydrdϕ signifies the volume of a body, which is<br />

and by a surface whose equation is ζ = y, if one considers those<br />
parts of the body as negative whose coordinates ζ are negative.<br />
However, here it will be tacitly assumed that the sixth surface will<br />
be continuous; if the latter condition comes to pass in such a way<br />
that y will be infinite, it can very well happen that the former conception<br />
no longer makes sense. In this case, there can be no talk<br />

Were questions proposed without restriction, which in certain arctan Θ − arc<br />
cases could become absurd, then analysis thereupon aids itself<br />
very frequently by delivering a response in part variable. If we,<br />
for example, signify the integral �� ��<br />
ydrdϕ<br />

� tu<br />
ydϕ =<br />

The integral in actuality can then only have a determined value,<br />
if y remains finite between the specified boundaries. This value<br />
is itself contained in the specified formula, however it is not fully<br />
determined by the same, since indeed the arctan is a multivalued<br />
function, and it must further become decided which functional<br />
values are preferable in a determined case, by means of other<br />
not-so-difficult considerations. If, on the contrary, y is infinite<br />
anywhere between the specified boundaries, then the question respecting<br />
the value of the integral �� 40<br />
ydrdϕ is absurd. This<br />
does not hinder, that, if one will obstinately extort a response<br />
from analysis, this might soon give different methods, whereby<br />
the individual values of the foregoing general formula are obtained.<br />

Gauss to Bessel<br />
December 18, 1811<br />
Correspondence<br />
Carl Gauss to Wilhelm Bessel<br />
December 18, 1811<br />
In this letter, Gauss responds to an assertion made by his student<br />
Bessel about the theory of numbers. Gauss used this opportunity to intervene<br />
on the way mathematicians had been thinking about their science, making clear<br />
that mathematics must represent an investigation of physics, not merely mathematical<br />
theorems.<br />
A<br />
few days ago, I finally recieved the Königsberger Archiv<br />
that I had ordered. With great interest, dear Bessel, I read<br />
through your first treatise, 1 and for now, have at least<br />
skimmed the other. That and the wonderful assistance, which it<br />
offers in the determination of li for large numbers, is now all the<br />
more agreeable to me, since I have recently obtained a beautiful<br />
table of factors from Ch e r n a C up to 1,020,000, appearing in this<br />
year of Deventer, with which I want to count up, little by little, the<br />
prime numbers from myriad to myriad, in order to compare them<br />
with the value of the integral<br />
� e x−1<br />
x dx<br />
a + b √reckoned from x = 0 on. You have made known to me the desire,<br />
that −1=a I report + bi this theorem in our GGA: before I do it, dear Bessel,<br />
our friendship obligates me to converse in writing with you<br />
li(a + about bi) one or another point, where my outlook is not entirely in<br />
� accord with yours. Therefore, kindly accept the following re-<br />
ϕ(x) marks · dx and, in the meantime, impart to me your thoughts just as<br />
frankly and candidly, as I mine. I think I can infer from one of<br />
α + βiyour<br />
casual remarks, that a basic principle is common to both of<br />
us: “In mathematics, there are no controversial truths,” and thus I<br />
x = a do + bi not doubt, that through the mutual exchange of our ideas, we<br />
will already be in agreement.<br />
ϕ(x) · dx First and foremost, from someone who wants to introduce<br />
a new function into analysis, I would ask for an explanation,<br />

he will understand them as applied to merely real mag-<br />
� nitudes (real values of the arguments of the function), and regard<br />
ϕ · dx the imaginary values of the arguments as if they were only quasioutgrowths;<br />
or whether he would accede to my principle, that, in<br />
ϕ(x) the realm of magnitudes, the imaginaries a + b<br />
ϕ(x) =∞<br />
√ −1=a + bi<br />
must enjoy equal rights with the reals. The discussion here is not<br />
of practical utility, rather, to me, analysis is li(a an independent + bi) science,<br />
which, by the neglect of those imaginary � magnitudes, loses<br />

which otherwise would be universally valid, are obliged to add<br />
the most weighty limitations. I must employ the assumption, that<br />
you are essentially in accordance with me about this point, since<br />

Without doubt imaginary, but it should follow the law of the continuity,<br />
being nowhere a break ex abrupto? If you then go from<br />
li(1.5+0.001i), while allowing the imaginary part 0.001i to decrease<br />
to 0, [to li 1.5], it absolutely does not come to a real value<br />
of li 1.5, but to one which depends upon -\pi i. With what you<br />
furnish for proof against eu l e r and myself, I find to criticize 1)<br />
that you say, if li x must become real in the whole circumference,<br />
then one must etc., but of course the onus lies not on us, if the<br />
continuity should not be lifted without cause, and it should even<br />
be proved, of course, that it should be taken as real in the whole<br />
circumference. 2) To be sure,<br />

is log y as well as log –y, but never both simultaneously, rather the<br />
former, if the integral � can begin from y – 1, the latter, if it begins<br />

if the first time C is set = 0, the second time<br />

The First Integral Calculus<br />
Bernoulli<br />
The First Integral Calculus<br />
A Selection from Johann Bernoulli’s Mathematical Lectures on the Method of Integrals and Other Matters<br />
Johann Bernoulli<br />
Translated by William A. Ferguson, Jr., from the German translation<br />
of Dr. Gerhardt Kowalewski.<br />
We have seen previously how to find the differentials<br />
of quantities. Now we will, inversely, show how the<br />
integrals of differentials are to be found, i.e., those<br />
quantities, from which the differentials are derived. Now it is already<br />
known from previous statements, that dx is the differential<br />
of 1<br />
2x2 x2dx 1<br />
3x3 1<br />
4x4 or 1<br />
2x2 x2dx 1<br />
3x3 1<br />
4x4 1<br />
2<br />
+ or – a constant quantity,<br />
x2<br />
x2dx 1<br />
3x3 1<br />
4x4 1<br />
2<br />
the differential<br />
of<br />
x2<br />
x2dx 1<br />
3x3 1<br />
4x4 1<br />
2<br />
or<br />
x2<br />
x2dx 1<br />
3x3 1<br />
4x4 + or – etc. and x3 1<br />
2<br />
dx the differential of<br />
x2<br />
x2dx 1<br />
3x3 1<br />
4x4 1<br />
2<br />
or<br />
x2<br />
x2dx 1<br />
3x3 1<br />
4x4 + or – a constant quantity, likewise also<br />
From this the following general rule can be formed:<br />
axp dx<br />
a<br />
p +1 xp+1<br />
ax<br />
is the differential of<br />
p dx<br />
a<br />
p +1 xp+1 .<br />
Therefore if the integral of any differential quantity is<br />
to be taken, then one must first of all consider, whether the given<br />
quantity is the product of any differential quantity multiplied by<br />
its “absolute quantity” raised to a certain power. This is then an<br />
indication that one can find the integral by the rule given above.<br />
If, for example, the integral of the quantity dy √ dy<br />
a + y is to be<br />
found, then I see first, that dy is multiplied by a multiple of its<br />
absolute quantity a + y, raised to the power a + y<br />
1<br />
2<br />
√ a + y<br />
a + y<br />
1<br />
2 ; next I seek its<br />
integral by the above rule, namely,<br />
1<br />
1<br />
1 + y) 2<br />
2 +1(a +1<br />
1<br />
1<br />
1 + y) 2<br />
2 +1(a<br />
, i.e.<br />
+1<br />
2<br />
3 (a + y)√ It should be noted, that sometimes quantities present<br />
themselves, whose integrals at first glance, it seems, cannot be<br />
found by this rule. Nonetheless, the dxintegral may easily be found<br />
after a certain transformation, as in the following cases.<br />
1. If one writes<br />
a + y<br />
.<br />
√ a2x2 + x4 xdx √ a2 + x2 ( 1<br />
3a2 + 1<br />
3x2 ) √ a2 + x2 instead of<br />
dx √ a2x2 + x4 xdx √ a2 + x2 ( 1<br />
3a2 + 1<br />
3x2 ) √ a2 + x2 dx<br />
, then one finds the integral of the latter, namely<br />
√ a2x2 + x4 xdx √ a2 + x2 ( 1<br />
3a2 + 1<br />
3x2 ) √ a2 + x2 dx<br />
. And if one writes<br />
√ a3 +3a2x +3ax2 + x3 (a dx + xdx) √ a + x<br />
2<br />
5 (a2 +<br />
(3ax 3 for dx<br />
dx<br />
√ a3 +3a2x +3ax2 + x3 (a dx + xdx) √ a + x<br />
2<br />
5 (a2 +2ax + x 2 ) √ a + x<br />
(3ax 3 dx +4x 4 dx) � ax + x2 dx<br />
, then one finds the integral<br />
√ a3 +3a2x +3ax2 + x3 (a dx + xdx) √ a + x<br />
2<br />
5 (a2 +2ax + x 2 ) √ a + x<br />
(3ax 3 dx +4x 4 dx) � ax + x2 dx<br />
.<br />
2. Also conversely it can occur, that one must pull one<br />
or more variables under the root sign, before the integral can be<br />
taken, as with the following example<br />
√ a3 +3a2x +3ax2 + x3 (a dx + xdx) √ a + x<br />
2<br />
5 (a2 +2ax + x 2 ) √ a + x<br />
(3ax 3 dx +4x 4 dx) � ax + x2 .<br />
The integral of this cannot be taken by our rule as it<br />
appears. However, if one pulls in an x (under the root sign), the<br />
result is<br />
(3ax 2 dx +4x 3 dx) � ax3 + x4 = 2<br />
3 (ax3 + x 4 ) � ax3 + x4 xdx<br />
a4 +2a2x2 + x4 (3ax<br />
,<br />
whose integral one finds by the rule<br />
2 dx +4x 3 dx) � ax3 + x4 = 2<br />
3 (ax3 + x 4 ) � ax3 + x4 xdx<br />
a4 +2a2x2 + x4 (3ax<br />
.<br />
3. If a fraction presents itself, whose denominator is a<br />
square, cube, or other power, then one must choose its root as the<br />
absolute quantity. Therefore, for<br />
2 dx +4x 3 dx) � ax3 + x4 = 2<br />
3 (ax3 + x 4 ) � ax3 + x4 (3ax<br />
xdx<br />
2 dx +4x 3 dx) � ax3 + x4 = 2<br />
3 (ax3 + x 4 ) � ax3 + x4 xdx<br />
a4 +2a2x2 + x4 (3ax 2 dx +4x 3 dx) � ax3 + x4 = 2<br />
3 (ax3 + x 4 ) � ax3 + x4 xdx<br />
a4 +2a2x2 + x4 (3ax 2 dx +4x<br />
= 2<br />

is to be chosen as the absolute quantity, and one obtains<br />
then<br />
2 + x2 −1 :(2a2 +2x2 )<br />
a4 +2a2x2 + x4 −1 :(2a<br />
. If one chose<br />
2 +2x2 )<br />
a4 +2a2x2 + x4 as the absolute<br />
quantity, then the integral of this fraction would not be<br />
obtainable by this rule.<br />
4. If the integrals of two quantities cannot be found individually,<br />
then sometimes it will be the case, that one can find the<br />
integral of their combination. Example:<br />

5. Sometimes, a fraction may seem not to have an integral,<br />
but if one multiplies its numerator and denominator by<br />
the same quantity, then its integral can be obtained easily. So it<br />
is with<br />

√<br />
3a +2x<br />

√<br />

Multiply the numerator and denominator by x. Then one obtains<br />
dx<br />

√<br />
3ax2 +2x3 √<br />
1<br />
3 3ax2 +2x3. 6. Conversely, sometimes the numerator and denominator<br />
are to be divided by the same quantity, in order to obtain its<br />
integral. Example:<br />
ax<br />
1<br />
2dx √<br />
a2x2 + x4 ax dx<br />
√<br />
a2 + x2 a √ a2 + x2 ax .<br />
Divide every term by x. Then one obtains<br />
2dx √<br />
a2x2 + x4 ax dx<br />
√<br />
a2 + x2 a √ a2 + x2 ax<br />
.<br />
Its integral follows by the rule:<br />
2dx √<br />
a2x2 + x4 ax dx<br />
√<br />
a2 + x2 a √ a2 + x2 .<br />
7. It also occurs sometimes, that the integral of a given<br />
quantity is not obtainable by the rule. If one however adds another<br />
quantity to it, whose integral one knows, something may be<br />
produced whose integral can be taken. Next, one subtracts from<br />
that integral the added quantity, therefore the remainder is the<br />
desired integral. Example: xdx √ a + x<br />
adx √ a + x<br />
(a dx + xdx) √ a + x<br />
= 2<br />
5 (a + x)2√a + x<br />
adx √ xdx<br />
.<br />
Because its integral cannot be taken by a simple<br />
method, add<br />
a + x<br />
√ a + x<br />
adx √ a + x<br />
(a dx + xdx) √ a + x<br />
= 2<br />
5 (a + x)2√a + x<br />
adx √ a + x<br />
2<br />
3 a(a + x)√ xdx<br />

(a dx + xdx) √ a + x<br />
= 2<br />
5 (a + x)2√a + x<br />
2<br />
3 a(a + x)√ xdx<br />
,<br />
whose integral is found by the rule to be equal to<br />
a + x<br />
√ a + x<br />

= 2<br />
5 (a + x)2√a + x<br />
adx √ a + x<br />
2<br />
3 a(a + x)√ xdx<br />
.<br />
If one subtracts from this the integral of<br />
a + x<br />
√ a + x<br />
adx √ a + x<br />

Admonition<br />
These are the most important cases in which integrals<br />
can be formed. Indeed several, even infinitely many others yet remain,<br />
with the help of which integrations are possible. However<br />
they do not all come to mind, and furthermore, most of them can<br />
be reduced to those cited here, so that with the help of these, the<br />
desired ones can be achieved; ultimately a thousand methods of<br />
solution and manifold cases according to the nature of the given<br />
quantities present themselves to the attentive observer. For this<br />
reason it were no less impossible than useless, were we to provide<br />
yet several others aside from those offered here.<br />
Let the one remark suffice, that important mathematical<br />
problems and theorems directly depend on the finding of integrals,<br />
both those already found as well as such as are yet desired to be<br />
found, as for example the quadrature of plane surfaces, the rectification<br />
of curves, the cubature of bodies, the method of inverse<br />
tangents, or the finding of the nature of a curve from given properties<br />
of its tangents, as well as that which belongs to mechanics,<br />
like the methods of finding the center of mass, of impulses, of oscillations,<br />
and so forth. Through the finding of integrals, one also<br />
obtains the involutions of curves, and the method by which to<br />
determine their nature, and with the help of the involute to rectify<br />
the curves themselves, as Ts c h i r n h a u s did with his caustics.<br />
The ease of finding the differential of any given quantity<br />
is matched, conversely, by the difficulty of finding the integral<br />
of any given differential, so that we at times cannot even confidently<br />
assert, whether the integral of the given quantity can be

rational quantity, which is multiplied or divided by x p� a2 − x2 , x p� ax − x2 , x p� a2 + x2 (a 3 + ax 2 − x 3 �<br />

(a4 + a3x + a2x2 − x4 , is either integrable or reducible to<br />
the quadrature of the circle or the hyperbola. This we will show<br />
in what follows. Therefore, above all, it is to be carefully considered<br />
whether the given quantity, which one would integrate, can<br />
be reduced by multiplication, division, or through the extraction<br />
of roots to a quantity which has one of these root terms, multiplied<br />
by a whole and rational quantity. If it is possible, then it is<br />
immediately a serious proposition, that the given quantity can be<br />
integrated; xif not, it is dependent on and reducible to the quadrature<br />
of the circle or the hyperbola.<br />
If, for example, the following quantity is given,<br />
)dx<br />
√<br />
ax + x2 1<br />
p� a2 − x2 , x p� ax − x2 , x p� a2 + x2 (a 3 + ax 2 − x 3 �<br />
a + x<br />
)dx<br />
x<br />
(a 3 + ax 2 − x 3 �<br />
a + x<br />
)dx<br />
x =<br />
(a4 + a3x + a2x2 − x4 ,<br />
and its integral is to be taken, then it appears at first glance neither<br />
to be integrable nor to have a relationship to the quadrature of the<br />
circle. In other words, if one assumes the absolute quantity to be<br />
that under the root sign, the fraction<br />
)dx<br />
√<br />
ax + x2 (a+x)<br />
sumed variable.<br />
This will be better clarified through an example. Let the<br />
quantity whose integral is desired be (ax + x<br />
, then its differential<br />
x<br />
will also be a fraction, so from that nothing can be concluded by<br />
the rule. Therefore I multiply the numerator and denominator of<br />
this irrational fraction by the numerator, and unite the product of<br />
the numerator with itself to the rational component of the quantity,<br />
so that a fraction results whose numerator is purely rational<br />
and whose denominator is irrational. Namely,<br />
This quantity now shows, that either it has an integral,<br />
or is reducible to the quadrature of the hyperbola. Rules will be<br />
given below, as to how this can be recognized and done.<br />
There remains yet something else, before we come to<br />
the use and application of the integral calculus. To wit, we will<br />
explain another procedure for the formation of integrals, which<br />
condenses the general method by more than a little. Because<br />
sometimes, due to the complexity of the given quantity, it is not<br />
immediately clear, whether it is of a kind which is reducible to<br />
one of the cases that we have presented before, and even, whether<br />
it has an integral or not. This procedure, however, reduces the<br />
quantity to fewer terms, so that one may find the desired integral<br />
without difficulty. This is done however, by taking the quantity<br />
under the root sign as the absolute quantity and setting it equal<br />
to some variable, and transforming the quantity to be integrated<br />
accordingly into another consisting only of terms of the assumed<br />
helping variable. One takes the integral of this quantity, which for<br />
the most part appears much simpler, which can be transformed<br />
back to the desired integral, by reinserting the value of the as-<br />

This rule can henceforth be applied in infinitely many<br />
cases, even in those which seem almost hopeless because of their<br />
complexity. Because, aside from the fact that this rule sometimes<br />
makes the quantity in question much briefer, it also offers the<br />
advantage, that it stands immediately before one’s eyes, whether<br />
the transformed quantity can be integrated.<br />
To all these methods of finding integrals one can add the<br />
following, which because of its usefulness and easiness, is almost<br />
preferable to all the rest. This method is however only relevant<br />
to those quantities which are combined with irrationals. Its whole<br />
application, accordingly, consists of transforming irrational quantities<br />

methods, but which can be done in the following manner.<br />
Since<br />
1<br />
3dx x √ ax − x2 √<br />
ax − x2 ax − x2 ax − x 2 = a2x2 m2 x = am2 :(a2 + m2 )<br />
√<br />
ax − x2 2 2 2 = a m :(a + m )<br />
dx =2a3mdm :(m2 + a2 ) 2<br />
a<br />
is an irrational quantity, then to make it rational,<br />
1<br />
3dx x √ ax − x2 √<br />
ax − x2 ax − x2 ax − x 2 = a2x2 m2 x = am2 :(a2 + m2 )<br />
√<br />
ax − x2 2 2 2 = a m :(a + m )<br />
dx =2a3mdm :(m2 + a2 ) 2<br />
a<br />
must become a square. Let therefore<br />
1<br />
3dx x √ ax − x2 √<br />
ax − x2 ax − x2 ax − x 2 = a2x2 m2 x = am2 :(a2 + m2 )<br />
√<br />

From this assumption<br />

a<br />
and consequently<br />

What’s the Matter with Descartes<br />
Vance<br />
Exclusive Interview: René Descartes<br />
What’s the Matter with Descartes?<br />
Timothy Vance<br />
There’s no denying it, folks.<br />
No matter how you slice it,<br />
there’s just no amount of<br />
geometric extension in the world<br />
that could bail out Descartes’ utterly<br />
bankrupt notion of moving<br />
bodies. You may keep trying to<br />
extend this matter of his if you like,<br />
but it still won’t move. “It’s impenetrable,”<br />
the experts may say.<br />
I don’t care, my friend. It’ll take<br />
a miracle from God to get those<br />
bodies of his moving again. Why?<br />
Because Descartes’ argument for<br />
motion lacks force ... and not just<br />
the kind necessary for convincing<br />
you he’s right, which, by the way,<br />
he would enjoy very much. This<br />
may seem a little suprising at first<br />
because René, as I like to call him,<br />
is a man whose books are still purchased<br />
every year by undergraduates<br />
enrolled in philosophy courses<br />
they can ill afford to take, and<br />
shouldn’t. He is a man who is credited with making mathematics<br />
“modern” by freeing Geometry from the tyranny of ... well, Geometry;<br />
And finally, Descartes is a man whom my loving friend<br />
Wilhelm Gottfried Leibniz would go out of his way on just about<br />
every occasion to refute. Naturally, such a reputation led me to<br />
expect more gravitas from Monsieur Descartes; instead, I found a<br />
man led astray (from making any damn sense) by too great a faith<br />
in his own genius and inflated sense of self–importance.<br />
What follows is a hastily arranged interview I conducted<br />
with Monsieur Descartes himself on Sepember 28 of this year:<br />
VANCE – Monsieur Descartes, thank you so much for<br />
taking the time to be with us today.<br />
DESCARTES – It really is my pleasure, and I’m very<br />
lucky to have actually made it here this evening. I had some<br />
trouble earlier today ...<br />
Tim Vance interviews René Descartes<br />
V – Trouble with your flight over the Atlantic?<br />
D – No, trouble getting out of bed. It’s where I draw the<br />
vast majority of my philosophical conclusions, you know; and<br />
it’s so very hard to find a nice quiet place these days for meditative<br />
contemplation (much more so if you have friends like mine).<br />
I’ve also discovered that one’s bed provides the perfect environment<br />
for thinking through life’s most challenging questions like<br />
“What can I know?” and “How can I know it?” – especially if<br />
doe in the late morning and early afternoon when everybody else<br />
is at work.<br />
V – You’ve been described by leading academics as “one<br />
of the most influential thinkers in human history.” That’s quite a<br />
remarkable statement! How did you come by all that knowledge<br />
which made you so famous?<br />
D – That’s a great question Tim, thanks so much for asking<br />
me. It’s really simple. “All that I have, up to this moment, ac-<br />

cepted as possessed of the highest truth and certainty, I received<br />
either from or through the senses.” 1 The idea for it came to me in<br />
a dream a few winters back. It was then that I discovered something<br />
very important which “got the ball rolling” so to speak–<br />
V – What did you discover?<br />
D – MYSELF! You know: Cogito ...<br />
V – Ergo sum?<br />
D – Yeah! Isn’t that great?<br />
V – Excusez–moi, Monsieur. Would you mind if I were<br />
to ask you a few simple questions concerning motion? It appears<br />
that my friend Leibniz could not have disagreed more with<br />
you on this very subject. He accuses you of preferring applause<br />
over certainty, or rather a fan–base over fact; and attributes your<br />
failure to properly describe the laws of nature–<br />
D – I FAILED?<br />
V – Well, before I answer you, René, let me ask: What<br />
is motion when it’s properly understood?<br />
D – Well, I am most sure of myself when I say “it is the<br />
translation of one part of matter, or of one body, from the vicinity<br />
of those bodies that are in direct contact with it and are viewed as<br />
at rest to the vicinity of others. Where by ‘one body’ or ‘one part<br />
of matter’ I understand everything that is transferred at the same<br />
time, even if this itself might again consist of many parts which<br />
have other motions in themselves. And I say that translation is not<br />
the force or action that transfers, as I shall show that this [motion]<br />
is always in the mobile, not in the mover.” 2<br />
V – Très bien, Monsieur. However, I became a little<br />
confused when you assigned the name “motion” to what is in fact<br />
only an effect of motion (namely “translation,” or a change from<br />
one place to another in a rectilinear fashion I presume), only to<br />
separate that effect immediately afterwards from its cause (that is,<br />
the “force or action that transfers”). You make little distinction<br />
between something which is moved, i.e. the mobile as you say,<br />
and that which moves, i.e. the mover.<br />
D – “It is not a matter of that action which is understood<br />
to be in the mover, or in that which arrests motion, but of translation<br />
alone and of the absence of translation, or rest.” 3<br />

V – But that would imply that–<br />
D – “[M]otion and rest ... are nothing other than two<br />
different modes–” 4<br />
V – Of the same thing?<br />
D – Yes, all corporeal substance.<br />
V – Substance made of what?<br />
D – Extension which is impenetrable.<br />
V – But how are things extended?<br />
D – How else are things extended through Euclidean<br />
space? By merely adding or subtracting individual points in the<br />
case of a line, or by adding and subtracting a series of points in<br />
the case of a surface, and so on.<br />
V – Euclid tells me a point has no parts. So what part of<br />
a point would make it impenetrable?<br />
D – I don’t know.<br />
V – I think you’re making it a lot harder for yourself<br />
by applying the same generic metric of “translation,” or the lack<br />
thereof, to both a body in motion and one at rest, and similarly<br />
applying it to any moving body regardless of whether it moves or<br />
is moved. Once again, why lump the two together?<br />
D – “[Because] no more action is required for motion<br />
than for rest.”<br />
V – But René, if no more action is required for motion<br />
than for rest, what has a body formerly at rest ever done in order<br />
to move? And if a moving object isn’t doing anything either, who<br />
or what has moved it?<br />
D – “God.” 5<br />
V – I see, très bien! And let me guess: “God is the primary<br />
cause of motion and always conserves the same quantity of<br />
motion in the universe.”<br />
D – “Mais oui.”<br />
V – Uh–huh ... Right.<br />

D – “[Well], it seems clear to me that it is nothing other<br />
than God Himself, who in the beginning created matter together<br />
with motion and rest and now conserves just as much motion and<br />
rest as a whole as He then posited. Now, although this motion in<br />
moved matter is nothing other than its mode, nevertheless it has<br />
a certain and determinate quantity, which we easily understand<br />
to be able to be always the same in the whole universe of things,<br />
even though it be changed in its individual parts.” 6<br />
V – For example ...?<br />
D – “[I]t is evident [...] when one part of matter is moved<br />
twice as fast as another, and this second [part of matter] is twice<br />
as large as the first, there is as much motion in the smaller as in<br />
the larger; and by as much as the motion of one part is made slower,<br />
the motion of some other equal to it is made faster. We also<br />
understand perfection to be in God, not only that He is immutable<br />
in Himself, but that he works in a most constant and immutable<br />
way, such that, save those changes that clear experience or divine<br />
revelation renders certain and that we believe or perceive to be<br />
made without any change in the Creator, we should suppose no<br />
other [changes] in His works, lest one then argue an inconstancy<br />
in Him. Whence it follows that it is most wholly in accord with<br />
reason that we think on this basis alone that God moved the parts<br />
of matter in various ways when He first created them and that He<br />
now conserves all of this matter clearly in the same way and for<br />
the same reason that He formerly created, and that He also conserves<br />
the same amount [tantundem] of motion in it always.” 7<br />
V – C’est magnifique! Except ...<br />
D – Except what?<br />
V – Except that doesn’t happen.<br />
D – Whatever ... C’est la vie.<br />
V – Descartes!<br />
D – “I will continue resolutely fixed in this belief, and<br />
if indeed by this means it be not in my power to arrive at the<br />
knowledge of truth, I shall at least do what is in my power, viz.,<br />
[suspend my judgment.]” Explain! 8<br />
V – Your straightforward example of two bodies which<br />
possess the same “quantity of motion” – or what you define as the<br />
product of mass times velocity – certainly pleases the senses. It<br />

Vance<br />
even works if we limit our investigation of motion to the common<br />
machines of antiquity, e.g. the lever, windlass, pulley, wedge, and<br />
screw – what is often referred to as “mechanics,” or “statics” to<br />
be more precise. But, as the great Monsieur Leibniz would point<br />
out, in all of those machines “there exists an equilibrium, since<br />
the mass of one body is compensated for by the velocity of the<br />
other” and that “the nature of the machine here makes the magnitudes<br />
of the bodies – assuming they are of the same kind – reciprocally<br />
proportional to their velocities, so that the same quantity<br />
of motion is produced on either side.” 9 Therefore, your law of<br />
motion only works by accident.<br />
D – It’s no accident. I didn’t look into any other kind<br />
of machine!<br />
V – You know, René, it wasn’t a pulley that put man on<br />
the moon ...<br />
D – The moon?<br />
V – Anyways, shall I now proceed to show an exception<br />
to your rule using a demonstration from Leibniz?<br />
D – I suppose if you must.<br />
V – Thank you ... First, assume that a body falling from<br />
a given height acquires the same force which is necessary to lift<br />
it back to its original height if its direction were to allow it, and<br />
there was no interference with its motion through friction, air–<br />
resistance, and the like.<br />
D – As for example with an ideal pendulum?<br />
V – Yes, exactly. Second, assume that the same amount<br />
of effort is consumed in raising a four–pound body to a height of<br />
one foot, as is consumed in raising a one–pound body to a height<br />
of four feet.<br />
D – I will generously grant Monsieur Leibniz these two<br />
assumptions, as will any of my pupils.<br />
V – Wonderful! Then a four–pound body falling one<br />
foot has acquired the same amount of force as a one–pound body<br />
falling four feet.<br />
D – Mais oui, for what you say is to me both “clear and<br />
distinct.”<br />

V – Except, the one–pound body acquires only two units<br />
of velocity.<br />
D – What of it?<br />
V – Descartes! Do the math ... shouldn’t it have acquired<br />
by your reasoning four units of velocity? Remember how<br />
evidently, you implied, a body twice as large as another would<br />
travel half as fast, thus always conserving the same quantity of<br />
motion? 10<br />
D – Aidez–moi! Do I have to show my work?<br />
V – Don’t worry about it. I’ll just assume you’ve actually<br />
calculated the results of this or any other physical experiment<br />
for that matter, ok?<br />
D – What a relief! Merci.<br />
V – But remember: Galileo’s proposition, and subsequent<br />
demonstrations show that a height is proportional to the<br />
square of the velocity of an object having fallen from it. Which<br />
means that, by your definition of ‘quantity of motion’, were we<br />
to construct a machine which would allow us to transfer all of the<br />
motion of the four–pound body falling one foot (previously in<br />
motion but now at rest) to the one–pound body (previously at rest<br />
but now set into motion), we would miraculously discover that<br />
such a one–pound body would be able to raise itself to a height<br />
of sixteen feet!<br />
D – What’s wrong with that?<br />
V – Well, earlier you had agreed with Leibniz when<br />
he asserted that as much effort was consumed in raising a four–<br />
pound body to a height of one foot, as was consumed in raising a<br />
one–pound body to height of four feet. Thus, with as much effort<br />
as was consumed in raising a one–pound body to a height of sixteen<br />
feet, we could have raised the four–pound body to a height<br />
of at least four feet. But we previously stated that the four–pound<br />
body in question originally fell from a height of one foot (before<br />
transferring its motion to the one–pound body), which should<br />
have only been enough to raise itself to a similar foot. Where did<br />
all that extra motion come from?<br />
D – Je ne sais pas. But I do know that such results could<br />
be used to produce some pretty interesting machines–<br />
V – Don’t even say it! Perpetual mechanical motion<br />
10 If Descartes’ total “quantity of motion” (mass times velocity)<br />
is to be preserved in this example, then m1 · v1 = m2 · v2 (here:<br />
4 times 1 = 1 times 4), i.e. a body of four pounds with one unit of<br />
velocity would impart four units of velocity to a one pound body.<br />
What’s the Matter with Descartes<br />

doesn’t exist. This is because, as Leibniz would say, there would<br />
be no reason for it to exist. For if effects could at any time exceed<br />
their causes, of what use would those causes be if not for producing<br />
all of their subsequent effects!<br />
D – How was I supposed to see that?!<br />
V – You weren’t! You don’t see causes, you know them<br />
by their power. And so the very things by which you correctly<br />
understand motion or change (powers), happens to be the name<br />
of a new science of motion founded by Leibniz 11 in opposition to<br />
yours and Newton’s. And so, while you sought to preserve the<br />
same quantity of motion, Monsieur Leibniz sought to preserve<br />
the same quantity of power, i.e. the equality of cause and effect.<br />
D – I see.<br />
V – René, all this “seeing” with your eyes got you into<br />
this trouble in the first place. You unfortunately assumed that<br />
there was nothing to be found in motion, or in corporeal bodies<br />
for that matter, which could not be measured through your senses.<br />
If indeed there was nothing more to it, then quantity of motion<br />
would consist of the only two things one could sense about a<br />
moving body, namely mass and velocity ... I mean, have you ever<br />
seen with your own two eyes actual squares on a velocity?<br />
D – [Non cogito–] <br />
[Note: Having over–extended himself at this point in<br />
the interview, Descartes was no more.]<br />
V – Ergo, it appears you no longer exist, and neither<br />
does the credibility of your methods.<br />
