We must not understand by that which is 'potentially capable of living' what has lost the soul it had but only what still retains it; but seeds and fruits are bodies which possess the qualification. Consequently while waking is actuality in a sense corresponding to the cutting and the seeing the soul is actuality in the sense corresponding to the power of sight and the power in the tool; the body corresponds to what exists in potentiality; as the pupil plus the power of sight constitutes the eye so the soul plus the body constitutes the animal.
