Abstract

The Nicomachean Ethics opens with some preparatory, although important, claims about the nature of the end for which all other things we do are said to be means. After having labelled this end “the highest good,” Aristotle asks: “Will not the knowledge of it, then, have a great influence on our way of life, and would we not [as a consequence] be more likely to attain the desired end, like archers who have a mark to aim at?”1 The question is never explicitly considered, but an affirmative answer presupposed. We have thus at least some reason to believe that Aristotle embraces a species of internalism when it comes to moral motivation, although, admittedly, Aristotle’s initial formulation is weak. He does not say that there is any necessary link between someone knowing that an act has the indicated role and being motivated to perform it, just that someone’s knowledge somehow will influence him in that direction. Nevertheless, we will see that Aristotle can be interpreted as an internalist of the qualified kind in the Nicomachean Ethics. It is reasonable to claim that Aristotle there embraces a specific sort of internalism, to the effect that a person is motivated to perform the acts which are virtuous for him to perform, actions which will make him happy, unless he suffers from some sort of epistemic defect. A person who is virtuous can be said to know what happiness is, and such a person is motivated to perform actions that result in happiness. Moreover, Aristotle can be interpreted as an internalist in the Humean tradition, in the sense that in order to be motivated to perform an action, desires are needed as well as beliefs.
