[658] Plato, Ap. Sok. c. 9, p. 23. I give here the sense rather than the exact words: Οὗτος ὑμῶν σοφώτατός ἐστιν, ὅστις ὥσπερ Σωκράτης ἔγνωκεν ὅτι οὐδενὸς ἄξιός ἐστι τῇ ἀληθείᾳ πρὸς σοφίαν.
Ταῦτ᾽ ἐγὼ μὲν ἔτι καὶ νῦν περιϊὼν ζητῶ καὶ ἐρευνῶ κατὰ τὸν θεὸν, καὶ τῶν ἀστῶν καὶ τῶν ξένων ἄν τινα οἴωμαι σοφὸν εἶναι· καὶ ἐπειδάν μοι μὴ δοκῇ, τῷ θεῷ βοηθῶν ἐνδείκνυμαι ὅτι οὐκ ἔστι σοφός.
[659] Plato, Ap. Sok. c. 9, p. 23, A-C.
... ἐν πενίᾳ μυρίᾳ εἰμὶ, διὰ τὴν τοῦ θεοῦ λατρείαν.
[660] Plato. Ap. Sok. c. 17, p. 29. Τοῦ δὲ θεοῦ τάττοντος, ὡς ἐγὼ ᾠήθην καὶ ὑπέλαβον, φιλοσοφοῦντά με δεῖν ζῆν, καὶ ἐξετάζοντα ἐμαυτὸν καὶ τοὺς ἄλλους, ἐνταῦθα δὲ φοβηθεὶς ἢ θάνατον ἣ ἄλλο ὁτιοῦν πρᾶγμα λίποιμι τὴν τάξιν.

[663] Plato, Ap. Sok. c. 28, p. 38, A. Ἐάν τε γὰρ λέγω, ὅτι τῷ θεῷ ἀπειθεῖν τοῦτ᾽ ἐστὶ, καὶ διὰ τοῦτ᾽ ἀδύνατον ἡσυχίαν ἄγειν, οὐ πείσεσθέ μοι ὡς εἰρωνευομένῳ· ἐάν τ᾽ αὖ λέγω ὅτι καὶ τυγχάνει μέγιστον ἀγαθὸν ὂν ἀνθρώπῳ τοῦτο, ἑκάστης ἡμέρας περὶ ἀρετῆς τοὺς λόγους ποιεῖσθαι καὶ τῶν ἄλλων, περὶ ὧν ὑμεῖς ἐμοῦ ἀκούετε διαλεγομένου καὶ ἐμαυτὸν καὶ ἄλλους ἐξετάζοντοσ—ὁ δὲ ἀνεξεταστὸς βίος οὐ βιωτὸς ἀνθρώπῳ (these last striking words are selected by Dr. Hutcheson, as the motto for his Synopsis Philosophiæ Moralis)—ταῦτα δὲ ἔτι ἧττον πείσεσθέ μοι λέγοντι.
