[22] πλεοναχῶς δ᾽ ὄντος τοῦ ἐπίστασθαι πῶς ἕκαστον μεταδιωκτέον ἀρχὴ καὶ μέγιστον ὁ οἰκεῖος τρόπος, οἷον τὰ πρῶτα καὶ νοητὰ καὶ τὰ κινητὰ καὶ ὑπὸ τὴν φύσιν, αὐτῶν δὲ τούτων τὰ ἐν ἀρχῇ καὶ
τὰ ἑπόμενα μέχρι ζώων καὶ φυτῶν καὶ ἐσχάτων τῶν ἀψύχων. ἔστι γάρ τι καθ᾽ ἕκαστον γένος ἴδιον ὥσπερ καὶ ἐν τοῖς μαθηματικοῖς.
