The paper demonstrates how Heidegger constructed his notion of an action without ends, or the ineffectual, through his early readings of Aristotle. Heidegger initially aligns the ineffectual with the notion of phronesis in Nicomachean Ethics, and later develops it further in Division 2 of Being and Time. The paper examines some of the implications of the conception of an action without ends. It shows that in fact the notion is absent from Aristotle and it is inconsistent. Finally, the paper briefly (...) explores the profound influence that the ineffectual has had on what came to be called in the United States ‘continental philosophy’. (shrink)
