Hedonism is the doctrine which holds that the good is whatever gives you pleasure and, therefore, pleasure is the standard of morality. Objectivism holds that the good must be defined by a rational standard of value, that pleasure is not a first cause, but only a consequence, that only the pleasure which proceeds from a rational value judgment can be regarded as moral, that pleasure, as such, is not a guide to action nor a standard of morality.
