Note 34 — Chapter XII · DE ANIMÂ, ETC.
Reading edition
Aristot. De Gener. Animal. II. i. p. 729, a. 10. Matter and Form are here compared to the female and the male — to mother and father. Form is a cause operative, Matter a cause co-operative, though both are alike indispensable to full reality. Compare Physic. I. ix. p. 192, a. 13: ἡ μὲν γὰρ ὑπομένουσα συναιτία τῇ μορφῇ τῶν γινομένων ἐστίν, ὥσπερ μήτηρ· — ἀλλὰ τοῦτ’ ἔστιν ἡ ὕλη, ὥσπερ ἂν εἰ θῆλυ ἄῤῥενος καὶ αἰσχρὸν καλοῦ (ἐφίετο). — De Partibus Animalium, I. i. p. 640, b. 28: ἡ γὰρ κατὰ τὴν μορφὴν φύσις κυριωτέρα τῆς ὑλικῆς φύσεως.
Metaphys. Z. iii. p. 1029, a. 5: τὸ εἶδος τῆς ὕλης πρότερον καὶ μᾶλλον ὄν — p. 1039, a. 1.
