Note 24 — Chapter XVIII · LACHES.
Reading edition
Plato, Lachês, 194. Καίτοι ἀήθης γ’ εἰμὶ (Lachês) τῶν τοιούτων λόγων· ἀλλά τίς με καὶ φιλονεικία εἴληφε πρὸς τὰ εἰρημένα, καὶ ὡς ἀληθῶς ἀγανακτῶ, εἰ οὑτωσὶ ἂ νοῶ μὴ οἷός τ’ εἰμὶ εἰπεῖν· νοεῖν μὲν γὰρ ἔμοιγε δοκῶ περὶ ἀνδρείας ὅ, τι ἔστιν, οὐκ οἶδα δ’ ὅπῃ με ἄρτι διέφυγεν, ὥστε μὴ ξυλλαβεῖν τῷ λόγῳ αὐτὴν καὶ εἰπεῖν ὅ, τι ἔστιν.
Compare the Charmidês p. 159 A, 160 D, where Sokrates professes to tell Charmides, If temperance is really in you, you can of course inform us what it is.
