Although Aristotle stated that we do not deliberate about ends, it is widely agreed that he did not mean it. Eager to save him from implying that ends are irrational, scholars have argued that he did recognize deliberation about the specification of ends. This claim misunderstands Aristotle’s conceptions of both deliberation and ends. Deliberation is not the whole of reasoning: it is a subcategory concerning only practical matters within our power. Not deliberating about something thus does not preclude other forms (...) of reflection on it, such as that involved in specification. Yet on Aristotle’s view, our ends are not in our power. They are generated not by individual choice but by nature, which in the case of human beings includes roles for both language and politics. Ends are thus beyond individual deliberation, though not beyond reason. This is no minor point. The claim that human beings can act rationally depends upon it. (shrink)
