Abstract

Aristotle, in his Nicomachean Ethics, considers how one becomes virtuous. However, when asking the question of how, he does not refer to ‘by friend’ as an option; all he refers to are ‘by learning’, ‘by training’, ‘by habituation’, ‘by god’ and ‘by luck’. Why does he not do so? First, I point out the fact that both Aristotle and Plato do not refer to the option of ‘by friend’ when asking the question of how. Second, I argue that Aristotle does not overlook the educational role of friendship. He understands that one needs friends. Third and finally, I consider the reason why Aristotle hesitates to emphasize the educational role of friendship and indicate that his theory of the mean causes it. This reveals the strained relationship between his theory of the mean and that of friendship in his ethical theory.
