Plutarch, De Iside et Osiride 58

χρηστέον δὲ τοῖς μύθοις οὐχ ὡς λόγοις πάμπαν οὖσιν, ἀλλὰ τὸ πρόσφορον ἑκάστου τὸ κατὰ τὴν ὁμοιότητα λαμβάνοντας. ὅταν οὖν ὕλην λέγωμεν, οὐ δεῖ πρὸς ἐνίων φιλοσόφων δόξας ἀποφερομένους ἄψυχόν τι σῶμα καὶ ἄποιον ἀργόν τε καὶ ἄπρακτον ἐξ ἑαυτοῦ διανοεῖσθαι· καὶ γὰρ ἔλαιον ὕλην μύρου καλοῦμεν, χρυσὸν ἀγάλματος, οὐκ ὄντα πάσης ἔρημα ποιότητος· αὐτήν τε τὴν ψυχὴν καὶ τὴν διάνοιαν τοῦ ἀνθρώπου ὡς ὕλην ἐπιστήμης καὶ ἀρετῆς τῷ λόγῳ κοσμεῖν καὶ ῥυθμίζειν παρέχομεν· τόν τε νοῦν ἔνιοι τόπον εἰδῶν ἀπεφήναντο καὶ τῶν νοητῶν οἷον ἐκμαγεῖον· ἔνιοι δὲ καὶ τὸ σπέρμα τῆς γυναικὸς οὐ δύναμιν οὐδʼ ἀρχήν, ὕλην δὲ καὶ τροφὴν γενέσεως εἶναι δοξάζουσιν. ὧν ἐχομένους χρὴ καὶ τὴν θεὸν ταύτην οὕτω διανοεῖσθαι τοῦ πρώτου θεοῦ μεταλαγχάνουσαν ἀεὶ καὶ συνοῦσαν ἔρωτι τῶν περὶ ἐκεῖνον ἀγαθῶν καὶ καλῶν, οὐχ ὑπεναντίαν ἀλλʼ ὥσπερ ἄνδρα νόμιμον καὶ δίκαιον ἐρᾶν ἐν δικαιοσύνῃ καὶ γυναῖκα χρηστὴν ἔχουσαν ἄνδρα καὶ συνοῦσαν ὅμως ποθεῖν λέγομεν, οὕτως ἀεὶ γλιχομένην ἐκείνου καὶ περὶ ἐκεῖνον λιπαροῦσαν καὶ ἀναπιμπλαμένην τοῖς κυριωτάτοις μέρεσιν καὶ καθαρωτάτοις·

We must not treat legend as if it were history at all, but we should adopt that which is appropriate in each legend in accordance with its verisimilitude. Whenever, therefore, we speak of material we must not be swept away to the opinions of some philosophers, and conceive of an inanimate and indifferentiated body, which is of itself inert and inactive. The fact is that we call oil the material of perfume and gold the material of a statue, and these are not destitute of all differentiation. We provide the very soul and thought of Man as the basic material of understanding and virtue for Reason to adorn and to harmonize, and some have declared the Mind to be a place for the assembling of forms and for the impression of concepts, as it were. Some think the seed of Woman is not a power or origin, but only material and nurture of generation. To this thought we should eling fast and conceive that this Goddess also who participates always with the first God and is associated with him in the love of the fair and lovely things about him is not opposed to him, but, just as we say that an honourable and just man is in love if his relations are just, and a good woman who has a husband and consorts with him we say yearns for him; thus we may conceive of her as always clinging close to him and being importunate over him and constantly filled with the most dominant and purest principles.
