Note 636 — Chapter VI · ARISTOTLE

On the theory of the Sophists, cf. above, pp. 16 f. On the Cynics, cf. infra; also Zeller, op. cit., II, 2, 376; Ar. Pol. 1253b20-23. Barker (op. cit., p. 359), who has a very clear and discriminating criticism of Aristotle’s theory of slavery, also states that slavery had been attacked by the “logic of events”—e.g., the enslavement of Athenians in Sicily, and the freeing of Messenian Helots, during the Theban supremacy, by which Greek freemen had become slaves and Greek slaves had become free. Cf. Pol. 1255a ff., especially 17 f. and 21-23, for the two theories.
