universe, which is the effect or production of such an energy, must be
consubsistent with its cause, or in other words, must be a perpetual
emanation from it. This will be evident from considering that every thing
which is generated, is either generated by art or by nature, or according
to power. It is necessary, therefore, that every thing operating
according to nature or art should be prior to the things produced; but
that things operating according to power should have their productions
coexistent with themselves; just as the sun produces light coexistent
with itself; fire, heat; and snow, coldness. If therefore the artificer
of the universe produced it by art, he would not cause it simply to be,
but to be in some particular manner; for all art produces form. Whence
therefore does the world derive its being? If he produced it from nature,
since that which makes by nature imparts something of itself to its
productions, and the maker of the world is incorporeal, it would be
necessary that the world, the offspring of such an energy, should be
incorporeal. It remains therefore, that the demiurgus produced the
universe by power alone; but every thing generated by power subsists
together with the cause containing this power: and hence production of
this kind cannot be destroyed unless the producing cause is deprived of
power. The divine intellect therefore that produced the sensible universe
caused it to be coexistent with himself.

This world thus depending on its divine artificer, who is himself an
intelligible world replete with the archetypal ideas of all things,
considered according to its corporeal nature, is perpetually flowing, and
perpetually advancing to being (en to gignesthai), and compared with its
paradigm, has no stability or reality of being. However, considered as
animated by a divine soul, and as receiving the illuminations of all the
supermundane gods, and being itself the receptacle of divinities from
whom bodies are suspended, it is said by Plato in the Timaeus to be a
