For it is not the case that, while the intelligence implanted in us by the Giver is fully competent to conjure up non-realities, it is endowed with no faculty at all for providing us with things that may profit us. But as the impulsive and elective faculty of the soul is established in our nature, to incite us to what is good and noble, though a man may also abuse it for what is evil, and no one can call the fact that the elective faculty sometimes inclines to evil a proof that it never inclines to what is good—so the bias of conception towards what is vain and unprofitable does not prove its inability for what is profitable, but, on the contrary, is a demonstration of its not being unserviceable for what is beneficial and necessary to the mind. For as, in the one case, it discovers means to produce pleasure or terror, so, in the other, it does not fail to find ways for getting at truth. Now one of the objects of inquiry was whether the First Cause, viz. God, exists without beginning, or whether His existence is dependent on some beginning. But perceiving, by the aid of thought, that that cannot be a First Cause which we conceive of as the consequence of another, we devised a word expressive of such a notion, and we say that He who is without anterior cause exists without origin, or, so to say, ungenerately. And Him Who so exists we call ungenerate and without origin, indicating, by that appellation, not what He is, but what He is not.
οὐ γὰρ πρὸς μὲν τὴν τῶν ἀνυπάρκτων διάπλασιν ἐντελὴς ἡμῖν ὁ νοῦς παρὰ τοῦ δεδωκότος ἐμπέφυκε, πρὸς δὲ τὴν τῶν ψυχωφελῶν εὕρεσιν οὐδεμίαν δύναμιν ποριστικὴν τῶν λυσιτελούντων κεκλήρωται: ἀλλὰ καθάπερ ἡ ὁρμητικὴ καὶ προαιρετικὴ τῆς ψυχῆς ἡμῶν δύναμις κατὰ μὲν τὸ προηγούμενον πρὸς τὴν τῶν καλῶν τε καὶ ἀγαθῶν ἔφεσιν ἐγκατεσκευάσθη τῇ φύσει, χρήσαιτο δ' ἄν τις καὶ πρὸς τὰ μὴ δέοντα τῇ τοιαύτῃ κινήσει, καὶ οὐκ ἄν τις εἴποι τοῦ πρὸς μηδὲν ἀγαθὸν τὴν προαίρεσιν ῥέπειν τεκμήριον εἶναι τὸ πρὸς τὰ φαῦλά ποτε τὴν ῥοπὴν ἔχειν, οὕτως καὶ ἡ περὶ τὰ μάταιά τε καὶ ἀνόνητα τῆς ἐπινοίας κίνησις οὐ κατηγορία τῆς πρὸς τὸ χρήσιμον ἀδυναμίας ἐστίν, ἀλλ' ἀπόδειξις γίνεται τοῦ καὶ πρὸς τὰ ψυχωφελῆ τε καὶ ἀναγκαῖα μὴ ἄπρακτος εἶναι. ὡς γὰρ ἐξεῦρεν ἐκεῖ τὸ πρὸς ἡδονὴν ἢ κατάπληξιν, οὕτω καὶ ἐνταῦθα τῶν πρὸς τὴν ἀλήθειαν ἐφόδων οὐχ ἁμαρτήσεται.
Ἓν δὲ τῶν ζητουμένων ἦν, εἰ τὸ πρῶτον αἴτιον, ὅ ἐστιν ὁ θεός, ἀνάρχως ἔστιν ἤ τινος ἀρχῆς ἐξημμένον ἔχει τὸ εἶναι. καταλαβόντες δὲ τῇ διανοίᾳ μὴ δύνασθαι πρῶτον εἶναι τὸ ἐξ ἑτέρου νοούμενον ἐπενοήσαμεν ὄνομα τῆς τοιαύτης ἐμφαντικὸν ὑπολήψεως καί φαμεν τὸν ἄνευ αἰτίας ὑπερκειμένης ὄντα ἀνάρχως εἴτουν ἀγεννήτως εἶναι. τὸν δὲ οὕτως ὄντα ἀγέννητον καὶ ἄναρχον ὠνομάσαμεν, οὐ τί ἐστιν, ἀλλὰ τί οὐκ ἔστι διὰ τοῦ ὀνόματος ἐνδεικνύμενοι.
