These suggestions of Mr. Mill are extremely interesting, because he was the last great modern thinker whose early training was not influenced by that prodigious expansion of scientific knowledge which, since the middle of the nineteenth century, has taken shape in the doctrine of evolution. This movement began early enough to determine the intellectual careers of eminent thinkers born between 1820 and 1830, such as Spencer and Huxley. Mr. Mill was a dozen years too old for this. He was born at nearly the same time as Mr. Darwin, but his mental habits were formed too soon for him to profit fully by the new movement of thought; and although his attitude toward the new ideas was hospitable, they never fructified in his mind. While his thinking has been of great value to the world, much of it belongs to an era which we have now left far behind. This is illustrated in the degree to which he was influenced by the speculations of Auguste Comte. Probably no two leaders of thought, whose dates of birth were scarcely a quarter of a century apart, were ever separated by such a stupendous gulf as that which intervenes between Auguste Comte and Herbert Spencer, and this fact may serve as an index to the rapidity of movement which has characterized the nineteenth century. Another illustration of the old-fashioned character of Mill's philosophy is to be seen in his use of Paley's argument from design in support of the belief in a beneficent Creator. Mill adopted this argument, and, as a professed free-thinker, carried it to the logical conclusion from which Paley, as a churchman, could not but shrink. This was the conclusion which I have already mentioned, that God's creative power has been limited by some inexplicable viciousness in the original constitution of things.
