Note 47 — Chapter XX · LYSIS.
Reading edition
Aristotel. Eth. Nikom. viii. 2, 1155, b. 12, viii. 5, 1157, a. 30, viii. 4; Eth. Eudem. vii. 2, 1236, a. 15. The statement is more full in the Eudemian Ethics than in the Nikomachean; he begins the seventh book by saying that φιλία is not said μοναχῶς but πλεοναχῶς; and in p. 1236 he says Ἀνάγκη ἄρα τρία φιλίας εἴδη εἶναι, καὶ μητε καθ’ ἓν ἁπάσας μηθ’ ὡς εἴδη ἑνὸς γένους, μήτε πάμπαν λέγεσθαι ὁμωνύμως· πρὸς μίαν γάρ τινα λέγονται καὶ πρώτην, ὥσπερ τὸ ἰατρικόν, &c. The whole passage is instructive, but is too long to cite.
Bonitz gives some good explanations of these passages. Observationes Criticæ in Aristotelis quæ feruntur Magna Moralia et Eudemia, pp. 55-57.
