The soul's faculty of growth remains to be considered. This at least
might be thought an inseparable entelechy. But neither does that suit
her nature. For if the principle of every plant is in its root, and if
growth takes place around and beneath it,[79] as occurs in many plants,
it is evident that the soul's faculty of growth, abandoning all the
other parts, has concentrated in the root alone; it, therefore, was not
distributed all around the soul, like an inseparable entelechy. Add
that this soul, before the plant grows, is already contained in the
small body (of the seed). If then, after having vivified a great plant,
the soul's faculty of growth can condense into a small space, and if
later it can, from this small space, again spread over a whole plant,
it is evidently entirely separable from the (plant's) matter.
