Cause Principle Unity

triangle, as it cannot be resolved into another figure, likewise cannot be
composed into triangles whose three angles are greater or smaller, even if
the triangles are diverse and varied, of diverse and varied types in terms of
greater or lesser size, minimal or maximal. Therefore, if you posit an infinite
triangle (I do not mean really and absolutely, since the infinite has no
figure; I mean infinite hypothetically, insofar as its angle is useful for our
demonstration), it will not have an angle greater than that of the smallest
finite triangle, and likewise for that of any intermediate triangle and of
another, maximum triangle.
But leaving off the comparison between one shape and another, I mean
between triangles, and considering angles, we see that they are all equal,
whatever their size, as in this square (fig. 2). This square is divided diagonally
into several triangles, and we see that not only are the angles of the
fig. 2.
three squares A, B and C equal, but also that all the acute angles resulting
from the division made by the said diagonal, which doubles the series of
triangles, are all equal. From this we can very clearly see, by a very marked
analogy, how the one infinite substance can be whole in all things, although
in some in a finite manner and in others in an infinite manner, in some in
lesser measure and in others in greater measure.
Add to this (to see further that, in this one, in this infinity, contraries
coincide) that the acute and the obtuse angles are two contraries. But do
you not see (fig. 3) that they are formed from a unique, undivided, identical
principle, that is, from the inclination made by the line M, which joins
perpendicularly the horizontal line BD at point C? Pivoting on point C,
and by a simple inclination towards point D, that perpendicular line, that
produces, first, two identical right angles and highlights, then, the difference
between the acute and the obtuse angle as it approaches point D. When it
