§4.30.1Ὁ μὲν χωρὶς χιτῶνος φιλοσοφεῖ, ὁ δὲ χωρὶς βιβλίου.
One man practices philosophy without a tunic, another without a book.
ἄλλος οὗτος ἡμίγυμνος· ἄρτους οὐκ ἔχω, φησί, καὶ ἐμμένω τῷ λόγῳ. —ἐγὼ δὲ τροφὰς τὰς ἐκ τῶν μαθημάτων οὐκ ἔχω καὶ ἐμμένω.
Here is another who is half-naked: "I have no bread," he says, "yet I abide by Reason." — And I, though I do not have the nourishment derived from learning, still abide by it.
