  Human beings should care about their own perfection as well as the perfection of others. As we have seen, the standard of perfection is objective in the sense that it guides, or should guide, human action, even if it what it recommends is not desired. These claims explain why perfectionism assigns an important place to self-regarding duties. A self-regarding duty to develop one’s talents, if there is such a duty, is categorical. One has the duty whether or not one has a desire to fulfill it.
