This project is a philosophical exploration of the common sense notion that achievements are among the things that make a life go well. Parts I and II develop an account of achievements as competently reached goals and discuss in virtue of what some such goals are more of an achievement than others. Part III argues that, given the account of achievements developed in parts I and II, we have good reason to think that the common sense idea is true: achievements are intrinsically valuable. We can see that this is so by reflecting on the fact that achieving our goals realizes certain valuable relations of harmony between mind and world.Ph.D
