usually mentioned fields of mathematics, i.e., geometry, arithmetic, astronomy,
optics, music, etc., but rather by its likeness and relationship to these
disciplines. It is similar to geometry in that it uses figures and symbols, to
music in its chants, to arithmetic in its numbers and manipulations, to
astronomy in its concerns for times and motions, and to optics in making
observations. In general, it is similar to mathematics as a whole, either
because it mediates between divine and natural actions, or because it shares
or lacks something of both. For some things are intermediates because they
participate in both extremes, others because they are excluded from both
extremes, in which case they should not be called intermediates but a third
species which is not between the other two but outside of them. From what
has been said, it is clear how divine and physical magic differ from the third
type.
To turn now to the particulars, magicians take it as axiomatic that, in all
the panorama before our eyes, God acts on the gods; the gods act on the
celestial or astral bodies, which are divine bodies; these act on the spirits
who reside in and control the stars, one of which is the earth; the spirits act
on the elements, the elements on the compounds, the compounds on the
senses; the senses on the soul, and the soul on the whole animal. This is the
descending scale.
By contrast, the ascending scale is from the animal through the soul to
the senses, through the senses to compounds, through compounds to the
elements, through these to spirits, through the spirits in the elements to
those in the stars, through these to the incorporeal gods who have an ethereal
substance or body, through them to the soul of the world or the spirit of the
universe; and through that to the contemplation of the one, most simple,
best, greatest, incorporeal, absolute and self-sufficient being.
Thus, there is a descent from God through the world to animals, and an
ascent from animals through the world to God. He is the highest point of
the scale, pure act and active power, the purest light. At the bottom of the
scale is matter, darkness and pure passive potency, which can become all
things from the bottom, just as He can make all things from the top.
Between the highest and lowest levels, there are intermediaries, the higher
of which have a greater share of light and action and active power, while the
lower levels have a greater share of darkness, potency and passive power.
As a result, all light in lower things, which comes to them from above, is
more powerful in higher things. And also, all darkness in higher things is
stronger in lower things. But the nature and power of light and darkness
