Note 1 — Chapter II · CHARACTER AND CHIEF FEATURES OF THE POST-ARISTOTELIAN PHILOSOPHY.

For the life of Zeno, Diogenes is the chief authority, who appears to be indebted for his information chiefly to Antigonus of Carystus, who lived about 250 B.C. In proof of this, compare the account of Diogenes with the extracts given by Athenæus (viii. 345, d; xiii. 563, e; 565, d; 603, e; 607, e; and, in particular, ii. 55, f) from Antigonus’ life of Zeno. Of modern authorities, consult Wagenmann, in Pauly’s Realencyclop. ↑
