Plato, Hippias Major, Hippias Minor, Ion, Menexenus, Cleitophon, Timaeus, Critias, Minos, Epinomis, Μίνως 36:

νεμεσᾷ γὰρ ὁ θεόσ, ὅταν τισ ψέγῃ τὸν ἑαυτῷ ὅμοιον ἢ ἐπαινῇ τὸν ἑαυτῷ ἐναντίωσ ἔχοντα· ἔστι δ’ οὗτοσ ὁ ἀγαθόσ. μὴ γάρ τι οἰού λίθουσ μὲν εἶναι ἱεροὺσ καὶ ξύλα καὶ ὄρνεα καὶ ὄφεισ, ἀνθρώπουσ δὲ μή· ἀλλὰ πάντων τούτων ἱερώτατόν ἐστιν ἄνθρωποσ ὁ ἀγαθόσ, καὶ μιαρώτατον ὁ πονηρόσ.
