We have not been able to show that reason requires the moral point of view, or that all really rational persons should not be individual egoists or classical amoralists. Reason doesn’t decide here. The picture I have painted for you is not a pleasant one. Reflection on it depresses me . . . . Pure practical reason, even with a good knowledge of the facts, will not take you to morality.
