[Ξενοκράτης] ἔλεγεν οὖν ἀριθμὸν μὲν τὴν ψυχὴν διὰ τὸ πλήρωμα εἰδῶν εἶναι τὴν ψυχὴν καὶ λόγον, ἐκ τῶν λόγων πάντων γὰρ ἐν ἑαυτῇ τοὺς λόγους ἔχει ὡς εἴπομεν· ἀριθμοὺς δὲ τὰ εἴδη ἐκάλουν ὡς εἴρηται, καὶ αὐτὸς γοῦν ἐν τοῖς ἑξῆς φησιν· καὶ εὖ δὴ οἱ λέγοντες τὴν ψυχὴν τόπον εἰδῶν, ἀριθμὸν μὲν οὖν διὰ τοῦτο· κινοῦντα δὲ αὑτὸν διὰ τὸ αὐτόζων αὐτῆς· οὐ γὰρ ὑφ’ ἑτέρου αὐτῇ τὸ ζῆν, αὐτοζωὴ γάρ ἐστιν.Fragmenta. Xenocrates of Chalcedon. ed. Friedrich Wilhelm August Mullach. Paris. 1881.
