αʹ Ὅτι ἀκατάληπτον τὸ θεῖον καὶ ὅτι οὐ δεῖ ζητεῖν
[Book III] Περὶ τῆς θείας οἰκονομίας καὶ περὶ τῆς δι' ἡμᾶς κηδεμονίας καὶ τῆς ἡμῶν σωτηρίας
Chapter XIX.—Concerning Thought.
The faculty of thought deals with judgments and assents, and impulse to action and disinclinations, and escapes from action: and more especially with thoughts connected with what is thinkable, and the virtues and the different branches of learning, and the theories of the arts and matters of counsel and choice433 Nemes., ch. 11.. Further, it is this faculty which prophesies the future to us in dreams, and this is what the Pythagoreans, adopting the Hebrew view, hold to be the one true form of prophecy. The organ of thought then is the mid-ventricle of the brain, and the vital spirit it contains434 Greg. Nyss., De opif. Hom., ch. 13..
Περὶ τοῦ διανοητικοῦ
Τοῦ δὲ διανοητικοῦ εἰσιν αἵ τε κρίσεις καὶ αἱ συγκαταθέσεις καὶ αἱ ὁρμαὶ πρὸς τὴν πρᾶξιν καὶ αἱ ἀφορμαὶ καὶ αἱ ἀποφυγαὶ τῆς πράξεως, ἰδικῶς δὲ αἵ τε νοήσεις τῶν νοητῶν καὶ αἱ ἀρεταὶ καὶ αἱ ἐπιστῆμαι καὶ τῶν τεχνῶν οἱ λόγοι καὶ τὸ βουλευτικὸν καὶ τὸ προαιρετικόν. Τούτου δέ ἐστι τὸ καὶ διὰ τῶν ὀνείρων θεσπίζον ἡμῖν τὸ μέλλον, ἥνπερ μόνην ἀληθῆ μαντείαν οἱ Πυθαγορικοὶ λέγουσιν εἶναι τοῖς Ἑβραίοις ἀκολουθήσαντες. Ὄργανον δὲ καὶ τούτου ἡ μέση κοιλία τοῦ ἐγκεφάλου καὶ τὸ ψυχικὸν πνεῦμα τὸ ἐν αὐτῇ.
