Note 48 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.
Oswald J. (Oswald Joseph) Reichel translation
See the expansion of this thought by Cleanthes (in Sext. Math. ix. 88–91) and the Stoics (in Cic. N. D. ii. 12, 33). Cicero distinguishes four kinds of beings—Plants, Animals, Men, and that being which is altogether reasonable and perfect deity. ↑
