Enneads IV.3: Psychological Questions
D. How Can the Soul Simultaneously Be Divisible and Indivisible?
A Decision Will Depend on the Meaning of the Terms
19. Must we consider that (in the soul), the indivisible and the divisible are identical, as if they were mingled together? Or should we consider the distinction between the indivisible and the divisible from some other point of view? Should the first be considered as the higher part of the soul, and the latter as the lower, just exactly as we say that one part of the soul is rational, and the other part is irrational? Such questions can be answered only by a close scrutiny of the nature of the divisibility and indivisibility of the soul.
