generate things similar to themselves. There is therefore another certain
cause prior to the above-mentioned nature, viz. a vegetable power itself.
But it is evident that all such things as are ingenerated in body as in a
subject, are of themselves incorporeal, though they become corporeal by
the participation of that in which they subsist, so that they are said
to be and are material in consequence of what they suffer from matter.
Qualities therefore, and still more natures, and in a still greater
degree the vegetable life, preserve the incorporeal in themselves. Since
however, sense exhibits another more conspicuous life, pertaining to
beings which are moved according to impulse and place, this must be
established prior to that, as being a more proper principle, and as the
supplier of a certain better form, that of a self-moved animal, and which
naturally precedes plants rooted in the earth. The animal however, is not
accurately self-moved. For the whole is not such throughout they whole;
but a part moves and a part is moved. This therefore is the apparent
self-moved. Hence, prior to this it is necessary there should be that
which is truly self-moved, and which according to the whole of itself
moves ands is moved, that the apparently self-moved may be the image of
this. And indeed the soul which moves the body must be considered as a
more proper self-moved essence. This, however, is twofold, the one
rational, the other irrational. For that there is a rational soul is
evident: or has not every one a cosensation of himself, more clear or
more obscure, when converted to himself in the attentions to and
investigations of himself, and in the vital and Gnostic animadversions of
himself? For the essence which is capable of this, and which can collect
universals by reasoning, will very justly be rational. The irrational
soul also, though it does not appear to investigate these things, and to
reason with itself, yet at the same time it moves bodies from place to
place, being itself previously moved from itself; for at different times
it exerts a different impulse. Does it therefore move itself from one
