[229] As shown by Prantl, 468, 171; on Diog. 76; Sext. Pyrrh. ii. 135;
Apul. Dogm. Plat. iii. 279, Oud. The latter rightly refers to the fact,
that Chrysippus discussed the main forms of hypothetical inference at
the very beginning of his doctrine of inference, Sext. Math. viii. 223.
[230] Anal. Pr. 87, b: δι’ ὑποθέσεως δὲ ἄλλης, ὡς εἶπεν (Arist. Anal.
Pr. i. 23, 41, a, 37) εἶεν ἂν καὶ οὓς οἱ νεώτεροι συλλογισμοὺς μόνους
βούλονται λέγειν· οὗτοι δ’ εἰσὶν οἱ διὰ τροπικοῦ, ὡς φασὶ, καὶ τῆς
προλήψεως γινόμενοι, τοῦ τροπικοῦ ἢ συνημμένου (conditional) ὄντος ἢ
διεζευγμένου (disjunctive) ἢ συμπεπλεγμένου (a copulative judgment
suggesting partly hypothetical judgments like the συμπεπλεγμένον in
Sext. Math. viii. 235, partly negative categorical judgments which have
the force of hypothetical judgments, such as: it is not at the same
time A and B. Conf. Diog. 80. Sext. Pyrrh. ii. 158; Matt. viii. 226.
Cic. De Fato, vi. 12). By the νεώτεροι, the Stoics must be meant, for
the terminology is theirs; and the Peripatetics, to whom it might
otherwise apply, always considered the categorical to be the original
form of judgment. See Prantl, 468, 172.
[231] Such an inference was called λόγος· when it was expressed in
definite terms, for instance, If it is day, it is light. The
arrangement of the clauses (which were designated by numbers, and not
by letters, as the Peripatetics had done), was called τρόπος· for
instance, εἰ τὸ πρῶτον, τὸ δεύτερον. A conclusion composed of both
forms of expression was a λογότροπος· for instance, εἰ ζῇ Πλάτων,
ἀναπνεῖ Πλάτων· ἀλλὰ μὴν τὸ πρῶτον· τὸ ἄρα δεύτερον. The premisses were
called λήμματα (in contrast to ἀξίωμα which expresses a judgment
independently of its position in a syllogism); or, more correctly, the
major premiss was λῆμμα, the minor πρόσληψις (hence the particles δὲ γε
were προσληπτικὸς σύνδεσμος, Apollon. Synt. p. 518, Bekk.). The
conclusion was ἐπιφορά, also ἐπιφορικοὶ συνδεσμοί. Ibid. 519. The major
premiss in a hypothetical syllogism was called τροπικόν, its two
clauses being called, respectively, ἡγούμενον (as by the Peripatetics)
and λῆγον (by the Peripatetics ἑπόμενον). Diog. 76; Sext. Pyrrh. ii.
135; Math. viii. 301, 227; Alex. l.c. and p. 88, a; 109, a; 7, b;
Philop. Anal. Pr. lx. a; Schol. in Arist. 170, a, 2; Ammon. on Anal.
Pr. 24, b, 19; Arist. Orig. ed. Waitz, i. 45; Apul. Dog. Plat. iii.
279, Oud.; Ps. Galen, Εἰσαγ. διαλ. p. 19.
[232] Alex. Anal. Pr. 116, b, after mentioning ἀμεθόδως περαίνοντες
συλλογισμοὶ, or inferences incomplete in point of form, such as: A = B,
B = C, ∴ A = C, which is said to want as its major premiss: Two things
which are equal to a third are equal to one another. On these ἀμεθόδως
περαίνοντες of the Stoics see l.c. 8, a; 22, b; Alex. Top. 10, Ps.
Galen, Εἰς. διαλ. 59. He then continues: οὓς ὅτι μὲν μὴ λέγουσι
συλλογιστικῶς συνάγειν, ὑγιῶς λέγουσι [οἱ νεώτεροι] ... ὅτι δὲ ἡγοῦνται
ὁμοίους αὐτοὺς εἶναι τοῖς κατηγορικοῖς συλλογισμοῖς ... τοῦ παντὸς
διαμαρτάνουσιν.
