Book 4
6.28
Arcesilaus, the son of Seuthes, according to Apollodorus in the third book of his Chronology, came from Pitane in Aeolis. With him begins the Middle Academy; he was the first to suspend his judgement owing to the contradictions of opposing arguments. He was also the first to argue on both sides of a question, and the first to meddle with the system handed down by Plato and, by means of question and answer, to make it more closely resemble eristic. He came across Crantor in this way. He was the youngest of four brothers, two of them being his brothers by the same father, and two by the same mother. Of the last two Pylades was the elder, and of the former two Moereas, and Moereas was his guardian.

At first, before he left Pitane for Athens, he was a pupil of the mathematician Autolycus, his fellow-countryman, and with him he also travelled to Sardis. Next he studied under Xanthus, the musician, of Athens; then he was a pupil of Theophrastus. Lastly, he crossed over to the Academy and joined Crantor. For while his brother Moereas, who has already been mentioned, wanted to make him a rhetorician, he was himself devoted to philosophy, and Crantor, being enamoured of him, cited the line from the Andromeda of EuripidesNauck, T.G.F.2, Eur. 129.: O maiden, if I save thee, wilt thou be grateful to me? and was answered with the next lineIb. 132.: Take me, stranger, whether for maidservant or for wife.
