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?
