Abstract

When discussing well-being, subject-relative concerns are intuitively important ones. In this article, I argue that Immanuel Kant's theory of well-being can be satisfactorily subject-relative, despite his emphasis on objective moral well-being. Because the specifics of agents’ situations affect agents’ moral endowments, duties regarding moral well-being can be altered for subject-relative reasons. When it comes to thinking about the well-being of others, the important Kantian notion of respect for rational agents ensures that this will be decidedly subject-relative, too, and, what is more, that this will be aimed specifically at natural well-being (happiness).
