Abstract
In “A Short Refutation of Ethical Egoism,” Richmond Campbell purports to refute “the view that everyone ought to do what benefits him the most in a given situation.” This is the theory which is “sometimes called impersonal ethical egoism ” [249). Campbell takes the following proposition as fundamental to his refutation of IEE.I. If an agent ought to do something in a given situation and another agent ought to do something in the same situation, then it is not logically impossible for them to do these things in that situation [250].Granted proposition I, Campbell's refutation would require only:II. There is a situation S where an agent M would benefit most from doing X and another agent N would benefit most from doing what would prevent M from doing X [251].
