Enneads IV.3: Psychological Questions
Soul Powers Remain the Same Throughout All Changes of Body
When numberless vermin arise out of the putrefaction of a body, they do not derive their life from the soul of the entire animal; the latter has abandoned the body of the animal, and, being dead, no longer dwells in the body. But the matter derived from putrefaction, being well suited for the generation of vermin, each receives a different soul, because the (universal) Soul is not lacking anywhere. Nevertheless, as one part of the body is capable of receiving her, while another is not, the parts that thus become animated do not increase the number of souls; for each of these little beings depends, as far as she remains one, on the single Soul (that is, on the universal Soul). This state of affairs resembles that in us. When some parts of our bodies are cut off, and when others grow in their place, our soul abandons the former, and unites with the latter, in so far as she remains one. Now the Soul of the universe ever remains one; and though amidst things contained within this universe, some are animate, while others are inanimate, the soul-powers nevertheless remain the same.
