THE ETHICS OF EVOLUTION

131. THE SIGNIFICANCE OF THE TITLE.--The title, "The Ethics of Evolution," seems to assume that the evolutionist, frankly accepting himself as such, must be prepared to join some school of the moralists different from other schools, and basing itself upon evolutionary doctrine.

That the ethical views of individuals and of communities of men may undergo a process of evolution or development is palpable. The ethical notions of the child are not those of the man, nor are the moral ideas of primitive races identical with those of races more advanced intellectually and morally.

But it is one thing to maintain that morals may be in evolution in individuals and in communities, and quite another to hold that the acceptance of the doctrine of evolution, broadly taken, forces upon one some new norm by which human actions may be judged. It was possible for as ardent an evolutionist as Huxley to hold that evolution and ethics are not merely independent, but are actually at war with one another, the competitive struggle for existence characteristic of the one giving place in the other to a new principle in which the rights of the weak and the helpless attain express recognition. [Footnote: HUXLEY, _Evolution and Ethics_, New York, 1894. See, especially, the _Prolegomena_.] And Sidgwick, that clearest of thinkers, maintains [Footnote: _The Methods of Ethics_, Book I, chapter vi, Sec 2.] that we have no reason to assume that it is our duty as moral beings simply to accelerate the pace in the direction already marked out by evolution.

It should be remembered that the word evolution may be used equivocally. It is not evident that all evolution is in the direction of a life, brute or human, that we commonly recognize as higher. There is retrogression, as well as progress, where such retrogression is favored by environment. We may call this, if we please, _devolution_. Were the conditions of his life very unfavorable, man could not live as he now lives; and, indeed, were they sufficiently unfavorable--for example, if the earth cooled off to a certain point--he could not live at all, but would have to give place to a lowlier creature better fitted to the conditions. Must the man who foresees this end approaching strive to hasten its arrival, or should he oppose it? In a decadent society, to come nearer to the problems which concern us in ethics, must a man strive to realize the social will expressed in progressive decadence? Should he hasten the decline of the community?

That those who study man as a moral being, like those who study man in any of his other aspects, will be more or less influenced in their outlook by the broadening of the horizon which results from a study of what the students of the evolutionary process have to tell us, may be conceded. But when we admit this, we do not necessarily have to look for a new norm by which to judge conduct. We seem, rather, forced to ask ourselves how this broadening of the horizon affects the norms which have heretofore appealed to men as reasonable. To be sure, any evolutionist has, in the capacity of a moralist, the right to suggest a new norm. But, in that case, he must, like any other moralist, convince us that it is a reasonable one.

132. EVOLUTION AND THE SCHOOLS OF THE MORALISTS.--Those who have suggested the norms discussed above, no one would think of as greatly influenced in their ethical teaching by the doctrine of evolution. Locke, Price, Butler and Sidgwick; Aristippus and Epicurus; Paley and Hobbes; Bentham and Mill; Epictetus and Marcus Aurelius; Janet, Green, and the rest, no one would be inclined to class simply as evolutionary moralists. Some of them never thought of evolution at all. How would it affect their standards of right and wrong were evolution expressly taken into account? Would the standards have to be abandoned? Or would the men, as broader men, merely have to revise some of their moral judgments?

(1) It might be supposed that the acceptance of evolutionary doctrine would bring into being a grave problem for the intuitionist, at least. If the body and mind of man are products of evolution, must we not admit as much of man's moral intuitions? Then why not admit that these may be replaced some day by other moral intuitions to be evolved in an unknown future?

He who reasons thus should bear in mind that Sidgwick, who by no means repudiated the doctrine of evolution, was an intuitionist, and placed his ultimate moral intuitions on a par with such mathematical intuitions as that two and two make four. If all intuitions are a product of evolution, Sidgwick might claim that the moral intuitions he accepts fare no worse than those elementary mathematical truths which we accept without question and without reflection. And he might maintain that an appeal to evolution need cast no greater doubt upon ultimate moral truth than upon mathematical. If intuitionism in all its forms is to be rejected, it seems as though it must be done upon some other ground than an appeal to evolution.

(2) As to the egoist. It is not easy to see how the appeal to evolution need disconcert him. Should he be so foolish as to maintain that egoism is always, in fact, necessary and unavoidable on the part of every living creature, he might easily be refuted by a reference to the actual life of the brutes, where altruism can be shown to play no insignificant role. But if he simply maintains that the only _reasonable_ principle for a man to adopt is egoism, he may continue to do so. He makes the self and its satisfactions his end. How can it concern him to learn how the self came to be what it is, or what it will be in the distant future? He panders to the present self; he may assume that it will be reasonable to pander at the appropriate time to the self that is to be, whatever its nature.

(3) The utilitarian remains such whether he makes the greatest good of the greatest number to consist in pleasure or in some other end, such as self-preservation. Some utilitarians, who have been inclined to emphasize the good of man, rather than to extend even to the brutes the goods to be distributed, may be influenced to extend the sphere of duties, if they will listen to the evolutionist, who cannot well leave out of view humbler creatures. [Footnote: "Thus we shall not go wrong in attributing to the higher animals in their simple social life, not only the elementary feelings, the loves and hates, sympathies and jealousies which underlie all forms of society, but also in a rudimentary stage the intelligence which enables those feelings to direct the operations of the animal so as best to gratify them."
