Reading edition
Plato, Legg. i. p. 631 B-D, iii. p. 697 B. This tripartite classification of Bona differs altogether from the tripartite classification of Bona given at the commencement of the second book of the Republic. But it agrees with that, the “tria genera Bonorum,” distinguished by Aristotle in the first Book of the Nikomachean Ethics (p. 1098, b. 12), among which τὰ περὶ ψυχήν were κυριώτατα καὶ μάλιστα ἀγαθά. This recognition of “tria genera Bonorum” is sometimes quoted as an opinion characteristic of the Peripatetics; but Aristotle himself declares it to be ancient and acknowledged, and we certainly have it here in Plato.
