Note 49 — Chapter III · * OTHER COMPANIONS OF SOKRATES.

Theophrastus wrote a treatise in three books on the solution of the puzzle called Ὁ ψευδόμενος (see the list of his lost works in Diogenes L. v. 49). We find also other treatises entitled Μεγαρικὸς ά (which Diogenes cites, vi. 22), — Ἀγωνιστικὸν τῆς περὶ τοὺς ἐριστικοὺς λόγους θεωρίας — Σοφισμάτων ά, β — besides several more titles relating to dialectics, and bearing upon the solution of syllogistic problems. Chrysippus also, in the ensuing century, wrote a treatise in three books, Περὶ τῆς τοῦ ψευδομένον λύσεως (Diog. vii. 107). Such facts show the importance of these problems in their bearing upon logical theory, as conceived by the ancient world. Epikurus also wrote against the Μεγαρικοί (Diog. x. 27).

The discussion of sophisms, or logical difficulties (λύσεις ἀπορίων), was a favourite occupation at the banquets of philosophers at Athens, on or about 100 B.C. Ἀντίπατρος δ’ ὁ φιλόσοφος, συμπόσιόν ποτε συνάγων, συνέταξε τοῖς ἐρχομένοις ὡς περὶ σοφισμάτων ἑροῦσιν (Athenæus, v. 186 C). Plutarch, Non posse suaviter vivi secundum Epicurum, p. 1096 C; De Sanitate Præcepta, c. 20, p. 133 B.
