Intellectual virtues are superior to moral virtues. The last three constitute scientific wisdom. Reflect on these and similar issues. Thus, nourishment and exercise, etc. are means to the end of bodily health. The health of the body is a means for the performance of moral actiions, which are in turn a means for the moral health of the soul.
Moral actions aim at personal and social stability.
Personal and social stability aim at scientific inquiry. There are levels of happiness. Why then should we not say that he is happy who is active in accordance with complete virtue and has sufficient external goods, not for a time but throughout a complete life. It would also include friendship, as we shall see. There is a great ambivalence and happy inconsistency in Aristotle.
