What we call natural selection in the animal world is in human history transformed, elevated, and idealised; it becomes social selection. We may call it natural, if we please; only, we must remember the greatly altered character of the agents concerned in it. While at every stage we see moral and intellectual growth, we must particularly remember that the new society for which socialists strive will consist of associated free beings acting under the regulation and stimulus of high ethical and artistic ends and ideals. Nothing, therefore, can be more narrow and one-sided than to consider the struggle for existence as the sole lever of human progress. Such one-sided insistence on the idea of struggle is to deny the whole ethical development of the world. Socialism professes to continue and promote the ethical and social development which we have described; on a higher plane of progress than has hitherto been reached to place the natural economic powers operating in human destiny under the regulation of reason, moral principle, and ideals of beauty; to render technical and mechanical appliances, and all the material and economic factors underlying human life, subservient to the well-being of man in a way hitherto unattained; and so to achieve the ethical freedom of man and his rational supremacy over the world. The competitive system is the latest phase in the struggle for existence, and socialism is the latest theory for the regulation of it along the well-approved lines of human progress. By such tests, none lower or narrower, must a rational socialism be tried. 2. There is, however, one side of this ethical progress which deserves to be more particularly considered. The ethical progress of man is largely a development of the principle of sociality, community, or association. This principle has its centre in the family, with all that is implied therein; in the association of man and woman, in the sacrifices made by both and especially by the mother for the children. Historically, it has developed from the tribe into ever wider and more complex forms—the city, nation, and race—until it more and more embraces the whole human family. That is, it finally tends to become international, so that the whole human family may be included in common ethical and social bonds—a state of things which is still far from being realised, but it is in process.
