According to some authors he was a pupil of Anaxagoras, and also of Damon, as Alexander states in his When Anaxagoras was condemned, he became a pupil of Archelaus the physicist; Aristoxenus asserts that Archelaus was very fond of him. Duris makes him out to have been a slave and to have been employed on stonework, and the draped figures of the Graces on the Acropolis have by some been attributed to him. Hence the passage in Timon’s Fr. 25 d.: From these diverged the sculptor, a prater about laws, the enchanter of Greece, inventor of subtle arguments, the sneerer who mocked at fine speeches, half-Attic in his mock humility. He was formidable in public speaking, according to Idomeneus; moreover, as Xenophon tells us, the Thirty forbade him to teach the art of words.

And Aristophanes attacks him in his plays for making the worse appear the better reason. For Favorinus in his says Socrates and his pupil Aeschines were the first to teach rhetoric; and this is confirmed by Idomeneus in his work on the Socratic circle.Possibly the reference is to the same citation as in 19 which Diogenes Laertius may have found independently in two of his authorities. Diogenes himself notices the agreement between Favorinus and Idomeneus of Lampsacus, a much earlier author, for he was a disciple of Epicurus, whom he knew from 310 to 270 b.c. Again, he was the first who discoursed on the conduct of life, and the first philosopher who was tried and put to death. Aristoxenus, the son of Spintharus, says of him that he made money; he would at all events invest sums, collect the interest accruing, and then, when this was expended, put out the principal again.

Demetrius of Byzantium relates that Crito removed him from his workshop and educated him, being struck by his beauty of soul;

that he discussed moral questions in the workshops and the market-place, being convinced that the study of nature is no concern of ours; and that he claimed that his inquiries embraced Whatso’er is good or evil in an houseHom. iv. 392.; that frequently, owing to his vehemence in argument, men set upon him with their fists or tore his hair out; and that for the most part he was despised and laughed at, yet bore all this ill-usage patiently. So much so that, when he had been kicked, and some one expressed surprise at his taking it so quietly, Socrates rejoined, Should I have taken the law of a donkey, supposing that he had kicked me? Thus far Demetrius.

Unlike most philosophers, he had no need to travel, except when required to go on an expedition. The rest of his life he stayed at home and engaged all the more keenly in argument with anyone who would converse with him, his aim being not to alter his opinion but to get at the truth. They relate that Euripides gave him the treatise of Heraclitus and asked his opinion upon it, and that his reply was, The part I understand is excellent, and so too is, I dare say, the part I do not understand; but it needs a Delian diver to get to the bottom of it.

He took care to exercise his body and kept in good condition. At all events he served on the expedition to Amphipolis; and when in the battle of Delium Xenophon had fallen from his horse, he stepped in and saved his life.

For in the general flight of the Athenians he personally retired at his ease, quietly turning round from time to time and ready to defend himself in case he were attacked. Again, he served at Potidaea, whither he had gone by sea, as land communications were interrupted by the warThe reason assigned for an expedition to Potidaea by sea will not hold. Communications between Athens and Thrace were, as a rule, made by sea. Moreover, the siege of Potidaea began in 432 b.c., the year before the outbreak of the Peloponnesian war. It has been suggested that the words διὰ θαλάττης ... κωλύοντος should properly follow Ἰσθμόν eight lines lower down. If any Athenian wished to attend the Isthmian games during the early part of the Peloponnesian war, it was probably safer not to risk the land journey owing to the bitter hostility of the Megarians.; and while there he is said to have remained a whole night without changing his position, and to have won the prize of valour. But he resigned it to Alcibiades, for whom he cherished the tenderest affection, according to Aristippus in the fourth book of his treatise Ion of Chios relates that in his youth he visited Samos in the company of Archelaus; and Aristotle that he went to Delphi; he went also to the Isthmus, according to Favorinus in the first book of his
