Nor need the perfectionist abandon his perfectionism in view of any such consideration. He who measures perfection by the degree of activity exercised in action, may admit that the coming man will be more perfect than it is possible for any man to be now; but that need not prevent him from holding that it is man's present duty to aim at the only perfection possible to him, he being what he is. Similar reasoning will apply to any other conception of perfection likely to be adopted, consciously or unconsciously, by any adherent of the school in question. As for the self-realizationist, a very little reflection seems sufficient to reveal that the maxim that it is man's duty to become all that it is in him to become is in no wise refuted by the claim that man may, in the indefinitely distant future, become much more than many people have supposed or now suppose. (5) There remains the doctrine of the Rational Social Will as furnishing the norm of conduct. I have tried to show that this doctrine must rest upon broad views of man and of man's environment. It is the very essence of the rational will to take broad views, to consider the past, the present, and the future. Surely the adherent of this school may let the evolutionist work in peace, may thank him for any helpful suggestions he has to offer, and may develop his own doctrine with little cause for uneasiness at the thought that information given him may refute his fundamental principle. However, it is not out of place for him to point out, if revolutionary measures of any sort are suggested by this or that evolutionist, that ethics is a discipline which is concerned with what men have to do, here and now. It must take into consideration what is advisable and feasible. Utopian schemes which break violently with the actual order of things and the normal development of human societies may be suggested by evolutionists, as they have been suggested by men who were not evolutionists at all. They are not to be taken much more seriously in the one case than in the other. 133. THE ETHICS OF INDIVIDUAL EVOLUTIONISTS.--Such considerations seem to make it evident that the acceptance of the doctrine of evolution should have no other influence upon us as moralists than that of making us take broad views of man and of his environment. It still remains to find a norm of conduct, and evolutionists, like other men, may develop ethical systems which are not identical. It is worth while here to touch very briefly upon the suggestions of one or two individual evolutionists. Those who speak of the ethics of evolution are very apt to have such in mind.
