Ἔοικα γοῦν τούτου γε σμικρῷ τινι αὐτῷ τούτῳ σοφώτερος εἶναι, ὅτι ἃ μὴ οἶδα οὐδὲ οἴομαι εἰδέναι → I seem, then, in just this little thing to be wiser than this man at any rate, that what I do not know I do not think I know either
Plato, Apology 21dGreek (Liddell-Scott)
λᾶς: λᾶος, ὁ, λίθος, Ἀττ. συνῃρ. ἀντὶ λᾶας, ὃ ἴδε.
