Abstract

A person's welfare or well-being concerns what is good for him, what makes his life worth living. It therefore depends crucially on facts about the person and his life. As William James once remarked, whether a life is worth living depends on the liver. How this dependency should be spelled out is a controversial question. Desire theorists, or as I shall call them well-being preferentialists, claim that a person's well-being depends on his desires and preferences.
