But, although the law of natural evolution cannot account, by survival of the fittest, for any progress made by universal benevolence, yet it may explain the value ascribed to the feeling of benevolence, when its object is the family or the community. Besides--as has already been pointed out--natural selection always implies an initiative got from elsewhere: it does not itself produce modifications; it only chooses out favourable ones and adds them together when produced. It always implies an independent modification of the organism; its part is to select the modifications best fitted to promote life. Hence the mere fact of benevolence being universalised is not in itself an anomaly on the theory of natural selection, any more than is the fact of its being extended from the family to the tribe. Only, the latter extension is one which it perpetuates, the former is not. No aspect of the theory of evolution seems able to account for an extension of the feeling of universal benevolence among different people or throughout different societies. This feeling has neither tended to promote the welfare of the race animated by it to the exclusion of other competing races--for there are no competing races whom it could affect--nor can it be shown that it makes the individuals possessing it fitter to wage successful war against opposing forces, than other individuals.[113] [Sidenote: Its result: shows the social nature of the individual.] Apart from such special difficulties, however, comparative psychology has shed a new light on the mental structure of the individual. The facts it brings forward show that the nature of the individual man cannot be explained without taking into account the relations in which he stands to society by birth, education, and business. He is, from the first, surrounded by, and dependent upon, other individuals, and by a set of established usages and institutions which modify his life; and he is connected with these in such a way that it is impossible to consider him as merely acted upon by them and influencing them in turn. He has been produced by, and has become a part of them. His physical and mental structure bears the marks of the same influences as those by which his so-called environment has been formed. He is cell in the "tissue" of which the body social is composed. This was partly recognised, it is true, before the theory of evolution had been elaborated. But the organic nature of the social union is confirmed by that theory, and erected into a scientific view of human life. [Sidenote: (b) Development of society.]
