Abstract
Eudemian Ethics II 6 is meant to introduce Aristotle's discussion of voluntary action in II 7–9. The majority of II 6, however, consists of a somewhat obscure discussion of the ways in which humans, alone among animals, are origins of action. It is not at all clear how that topic is meant to relate to the topic of voluntary action until the following passage, towards the end of the chapter, in which Aristotle relates being the cause and origin of action to praiseworthiness and blameworthiness and to the voluntary : ἐπεὶ δ’ ἥ τε ἀρετὴ καὶ ἡ κακία καὶ τὰ ἀπ’αὐτῶν ἔργα τὰ μὲν ἐπαινετὰ τὰ δὲ ψεκτά καὶ ἐπαινεῖται οὐ διὰ τὰ ἐξ ἀνάγκης ἢ τύχης ἢ φύσεωςὑπάρχοντα, ἀλλ’ ὅσων αὐτοὶ αἴτιοι ἐσμέν· ὅσων γὰρ ἄλλοςαἴτιος, ἐκεῖνος καὶ τὸν ψόγον καὶ τὸν ἔπαινον ἔχει), δῆλονὅτι καὶ ἡ ἀρετὴ καὶ ἡ κακία περὶ ταῦτ’ ἐστιν ὧν αὐτὸςαἴτιος καὶ ἀρχὴ πράξεων. ληπτέον ἄρα ποίων αὐτὸς αἴτιος καὶ ἀρχὴ πράξεων.Now, since virtue and vice and the works that come from them are praiseworthy and blameworthy respectively, it is clear that virtue and vice are concerned with what one is oneself a cause of and starting point of action.
