Abstract
Most moral theories purport to make claims upon agents, yet often it is not clear why those claims are ones that can be justifiably demanded of agents. In this paper, I develop a justification of moral requirements that explains why it is that morality makes legitimate claims on agents. This justification is grounded in the idea that there is an essential connection between morality and psychological well-being. I go on to suggest how, using this justification as a springboard, we might be able to develop a viable theory of moral requirements that maintains the strict and demanding status we take to be distinctive of moral requirements, yet avoids worries of alienation.
