 There is another contrast with Plato that should be emphasized: In Book II of the Republic, we are told that the best type of good is one that is desirable both in itself and for the sake of its results (357d–358a). Plato argues that justice should be placed in this category, but since it is generally agreed that it is desirable for its consequences, he devotes most of his time to establishing his more controversial point—that justice is to be sought for its own sake. By contrast, Aristotle assumes that if A is desirable for the sake of B, then B is better than A (1094a14–16); therefore, the highest kind of good must be one that is not desirable for the sake of anything else. To show that A deserves to be our ultimate end, one must show that all other goods are best thought of as instruments that promote A in some way or other. Accordingly, it would not serve Aristotle’s purpose to consider virtuous activity in isolation from all other goods. He needs to discuss honor, wealth, pleasure, and friendship in order to show how these goods, properly understood, can be seen as resources that serve the higher goal of virtuous activity. He vindicates the centrality of virtue in a well-lived life by showing that in the normal course of things a virtuous person will not live a life devoid of friends, honor, wealth, pleasure, and the like. Virtuous activity makes a life happy not by guaranteeing happiness in all circumstances, but by serving as the goal for the sake of which lesser goods are to be pursued. Aristotle’s methodology in ethics therefore pays more attention than does Plato’s to the connections that normally obtain between virtue and other goods. That is why he stresses that in this sort of study one must be satisfied with conclusions that hold only for the most part (1094b11–22). Poverty, isolation, and dishonor are normally impediments to the exercise of virtue and therefore to happiness, although there may be special circumstances in which they are not. The possibility of exceptions does not undermine the point that, as a rule, to live well is to have sufficient resources for the pursuit of virtue over the course of a lifetime.
