Note 109 — Chapter V · LOGIC OF THE STOICS.

Diog. 71; Sext. Math. 109; Galen, De Simpl. Medicamen. ii. 16, vol. xi. 499; Ps. Galen, Εἰσαγ. διαλ. p. 15. The Stoics distinguish most unnecessarily, but quite in harmony with their ordinary formal punctiliousness, the case in which the leading clause is identical with the inferential clause (εἰ ἡμέρα ἐστὶν, ἡμέρα ἔστιν) and the case in which it is different (εἰ ἡμέρα ἐστὶν, φῶς ἔστιν). Conditional sentences of the first kind are called διφορούμενα συνημμένα. Sext. viii. 281; 294; and 466; Pyrrh. ii. 112; conf. viii. 95; Diog. 68. That in all these passages διφορούμενον must be read, and not διαφορούμενον, appears according to Prantl’s (p. 445, 122) very true observation from the remarks of Alex. Top. 7, a; Anal. Pr. 7, b, on διφορούμενοι συλλογισμοί. ↑
