not follow that you should act so that your act may be the maxim of universal legislation. Why should not a man feel that an act is for him moral, that could not become the norm of others' conduct? The criterion: What would happen, if all acted like me? cannot avail in some cases, because if all acted uniformly, no evil would result. Besides, why make such a demand, when we are sure that all will not act in the same way? The demand is based on the belief that morality would be furthered if the agent's moral act were to become general, which is not the case. An end may, perhaps, be best realized, if A acts in a certain way, and B acts differently under the same circumstances. We must reckon with the fact that personalities differ.
The book will be found to be of great value to students of ethics, and should be carefully considered by writers on moral subjects.
