EN 1096a34-b5 No difference between a thing and a thing itself in definition

ἀπορήσειε δ' ἄν τις τί ποτε καὶ βούλονται λέγειν αὐτοέκαστον, εἴπερ ἔν τε αὐτοανθρώπῳ καὶ ἐν ἀνθρώπῳ εἷς καὶ ὁ αὐτὸς λόγος ἐστὶν ὁ τοῦ ἀνθρώπου. ᾗ γὰρ ἄνθρωπος, οὐδὲν διοίσουσιν· εἰ δ' οὕτως, οὐδ' ᾗ ἀγαθόν. ἀλλὰ μὴν οὐδὲ τῷ ἀίδιον εἶναι μᾶλλον ἀγαθὸν ἔσται, εἴπερ μηδὲ λευκότερον τὸ πολυχρόνιον τοῦ ἐφημέρου.
