Of this volume, which was a criticism not only of Mr. Kidd, but of Mr. Herbert Spencer also, the fundamental thesis was similar to that of _Social Equality_, and of _Labor and the Popular Welfare_--namely, that in proportion as societies progress in civilization and wealth all appreciable progress, and the sustentation of most of the results achieved by it, depend more and more on the directive ability of the few; and this thesis was affiliated to the main conclusions of evolutionary science generally. It was admitted that, within certain limits, results achieved by the few were absorbed and perpetuated by the many, though the activities of the originators might have ceased, and that a proper definition of evolution pure and simple would be: "The orderly sequence of the unintended." But, at the same time, it was shown that an "orderly sequence of the unintended," though it is a part of what we mean by progress, is a small part only, the major part still requiring the intentional activities of the few, not only for its initiation, but for its sustentation also. This argument was set forth with great minuteness, and it was shown how many most distinguished thinkers, while admitting its general truth, were constantly obscuring it by formulae which were, in effect, denials of it. Among the writers thus referred to was Mr. Herbert Spencer, who in one passage described the Napoleonic wars as an incident in the process of evolution and in another passage cited them as examples of the results of the solitary wickedness of one super-capable man. With regard to these issues I received some interesting letters from Mr. Spencer himself. His contention was that I had quite misrepresented his meaning. Economically, at all events, the functions of the super-capable man were in his opinion as important as they possibly could be in mine. I replied that if such were his opinion he very often obscured it, but that I hoped he would acquit me of any conscious unfairness to himself. His first letters were not without a touch of acerbity, but he ended with amicably stating what his actual views were, and saying that if I only amended certain passages relating to himself, he was in entire agreement with my whole argument otherwise. [Illustration: HERBERT SPENCER] I never met Mr. Spencer, and of what he may have been in conversation I have not the least conception; but a story is told of him which shows that he must have had a vein of humor in him which his writings do not suggest. His favorite relaxation was billiards. This game he played with more than average skill, but on one occasion, much to his own chagrin, he found himself hopelessly beaten by a very immature young man. "Skill in billiards, up to a certain point, is a sign," he said, "of sound self-training. Too much skill is a sign of a wasted life."
