Note 2 — Chapter VIII · ANALYTICA POSTERIORA II.
Reading edition
Schol. Philopon. p. 241, a. 18-24: τούτων τὸ εἰ ἔστι καὶ τὸ τί ἐστιν εἰσὶν ἁπλᾶ, τὸ δὲ ὅτι καὶ τὸ διότι σύνθετα — πρότερα γὰρ ἡμῖν καὶ γνωριμώτερα τὰ σύνθετα, ὡς τῇ φύσει τὰ ἁπλᾶ.
Mr. Poste observes upon this quadruple classification by Aristotle (p. 96):— “The two last of these are problems of Inductive, but first principles of Deductive, Science; the one being the hypothesis, the other the definition. The attribute as well as the subject must be defined (I. x.), so that to a certain degree the second problem also is assumed among the principles of Demonstration.”
