 (P′) now is simply a different formulation of the (IC): if we accept the (IC) then we should accept (P′). But what happens, then, if we grant the truth of Descriptive Hedonism: namely, that only pleasure is, in fact, desired. In that case, it would now follow that only pleasure is desirable (ought to be desired) (assuming, again, that Value Nihilism is false). That is, since something ought to be desired only if it can be desired (internalism), then if only x can be desired, then only x ought to be desired (assuming that Value Nihilism is false).
