Defending Pure Moral Deference: an Argument from Rationality

Pessimists about moral deference argue that there is something special about moral beliefs which make it impermissible for agents to defer on moral matters. In this paper, I argue that, even if pessimists are right that there is something special about moral beliefs, that is not enough to render moral deference impermissible. A stronger requirement—the rationality requirement—makes deferring to experts not only permissible but also rationally required. When one does not defer to one’s perceived moral expert, one either violates Belief Consistency or violates Belief Closure. The moral considerations, such as moral understanding or virtue, for not deferring to experts either fail to show that not deferring is a better option than deferring or fail to show that those moral considerations outweigh rationality requirements.
