 * 1845,, Moral and Metaphysical Philosophy (second edition, revised; , First Division: Pure Sciences), part I: Ancient Philosophy (1850), chapter vi: “Grecian Philosophy”, division iii : ‘Aristotle’, § 6: «Aristotelian Psychology», ¶ 3: ‹Distinction of Souls›, page 199:
 * But all living creatures have not a soul exercising the same δυνάμεις. We may define all the faculties which can exist in any living creature to be these: first, the faculty of receiving nourishment (θρεπτική); secondly, the faculty of sensation (ἀισθητική); thirdly, the faculty of motion in place (κινητική); fourthly, the faculty of impulse or desire (ὀρεκτική); fifthly, the faculty of intelligence (διανοητική). The threptic faculty is the lowest of these, and is present in all cases. The soul, therefore, as endued with this one faculty, may be attributed to vegetables.
