In Mr. Spencer’s doctrine the two sides above indicated have been brought into very marked relation by a suggestive criticism, [1] which he has taken special pains to answer. If human society corresponds to an individual organism--as is, in many ways, Mr. Spencer’s well-known doctrine--how is it that the absolute central control in which the perfection of an organism consists is, for Mr. Spencer, a note of imperfection when it appears in a human society? And the answer is in effect that human society corresponds in many of its features rather to a local variety of a species than to an individual organism. It is essentially discrete, not individual, and at this point, therefore, the analogy of the individual organism gives way to that of the group or species. [1] _Sociology_, i. 586. But Mr. Spencer does not really mean that a human society has no more intrinsic bond between its members than the local group of an animal species. To indicate its true nature he {26} gives us a good word--but a word only--the word “super-organic.” [1] It is a significant term, and brings us perhaps to the limit of what biological sociology is able to suggest with regard to the unity of a human commonwealth, and points us to something beyond. It is remarkable that when the facts of true human society are more thoroughly realised than by Mr. Spencer, but the clue of the individual organism and the co-operative side of animal life is not followed up, there is a tendency to sever the links which unite man to “lower” nature, and to represent the ethical and cosmic processes as absolutely opposed. We see this point of view decidedly adopted by Mr. Huxley, [2] and its adoption perhaps indicates the inception of an epoch in which sociology will cut itself free from a good deal of pseudo-scientific lumber. Nevertheless, a patient and careful study will continue to recognise the elements both of competition and of co-operation as ineradicable and inseparable moments in human society as in the animal world; the essential meaning of competition in its higher forms being the rejection and suppression of members who are unable to meet the ever advancing demand for co-operative character and capacity; and the study of parasitism [3] and of regressive selection will continue to {27} be a warning against the attempt to emancipate mankind from the sterner general conditions of the cosmic order. It will be recognised that there is an adaptation to conditions which consists in degradation; but the failure will be understood by comparison with the only true “survival of the fittest,” [4] being that which reveals the full unity and significance of organism and environment. It is important to observe that, at least in the two eminent biologists just alluded to, the doctrine of the individual self--of the relation between self-assertion and self-restraint--is altogether of an uncivilised and anti-social type. Biological categories do not, in their case
