§52.1Fr. 52
Δημόκριτος δὲ, ὡς Θ. ἐν τοῖς φυσικοῖς ἱστορεῖ, ὡς ἰδιωτικῶς ἀποδιδόντων τῶν κατὰ τὸ θερμὸν καὶ τὸ ψυχρὸν καὶ τὰ τοιαῦτα αἰτιολογούντων, ἐπὶ τὰς ἀτόυν μους ἀνέβη.
Democritus, as Theophrastus records in his Physics, because he thought that those who explain causes by means of the hot and the cold and such things give their explanations in an amateurish way, ascended to atoms.
