Note 135 — Chapter V · LOGIC OF THE STOICS.

Compare the remarks of Prantl, 481, on Sext. Pyrrh. ii. 2; Alex. Anal. Pr. 53, b; Galen, l.c.; Ps. Galen, Εἰσαγ. διαλ. 57. If Posidonius, according to the latter passage, calls analogical conclusions συνακτικοὺς κατὰ δύναμιν ἀξιώματος, and the Stoics also, according to Schol. in Hermog. Rhet. Gr. ed. Walz, vii. 6, 764, spoke of a κατὰ δύναμιν τροπικὸν, we have already met with the same thing, p. 119, 1, where an analogical conclusion was included in the ἀμεθόδως περαίνοντες, which, by the addition of an ἀξίωμα, can be changed into regular conclusions. In the doctrine of proof the τόπος παράδοξος was also treated of, according to Procl. in Euclid, 103, being probably suggested by the ethical paradoxes of the Stoics. ↑
