Pindar Fragment 61 (but taken from v.2 of the Loeb Early Greek Philosophy set):
What do you expect wisdom to be, if it is only by a little
That one man possesses it more than another?
For it is impossible for him
To discover the gods’ plans with a human mind (phreni):
He was born of a mortal mother.
τί ἔλπεαι σοφίαν ἔμμεν, ἃν ὀλίγον τοι
ἀνὴρ ὑπὲρ ἀνδρὸς ἴσχει;
οὐ γὰρ ἔσθ᾽ ὅπως τὰ θεῶν
βουλεύματ’ ἐρευνάσει βροτέᾳ φρενί·
θνατᾶς δ᾽ἀπὸ ματρὸς ἔφυ.
