Φυσικὴ τοίνυν ἐστὶ θερμότης, τὴν αὐτὴν δέ φημι καὶ ἔμφυτον δήπου θερμόν, ᾗ ἡ ἀρχὴ τοῦ ζῴου ἡ φύσις· συμφύεται γὰρ τῷ ζῴῳ, καὶ διὰ τοῦτο λέγεται φυσική, ὄργανον οὖσα καθόλου τῶν τῆς ψυχῆς δυνάμεων· οὐδὲ γὰρ οἷόν τε τὴν ψυχὴν ἄνευ τοῦ τοιούτου θερμοῦ παράξαι τινὰ τὴν τυχοῦσαν ἐνέργειαν. Ἅπαν γε μὴν ὄργανον ἀνάλογόν τε ἐκείνῳ δεῖ εἶναι, οὗ ἐστιν ὄργανον, καὶ τὸν προσήκοντα λόγον πρὸς τὸ ἔργον καὶ τὸ ἀποτέλεσμα σώζειν. ἄλλως γὰρ τό,τε ὄργανον τό,τε οὗ ἐστιν ὄργανον, καὶ τὸ δι᾽ ὃ τὸ ὄργανον, μάτην ἂν εἴη, καὶ οὕτως ἐν τοῖς οὖσι καθ᾽ αὑτὸ δήπου τι μάτην συνεισαχθείη.
