It would be little to my credit, however, had my views of the doctrine of evolution and its implications undergone no development or enlargement since the publication of "Cosmic Philosophy." To carry such a subject about in one's mind for ten years, without having any new thoughts about it, would hardly be a proof of fitness for philosophizing. I have for some time been aware of a shortcoming in the earlier work, which it is the purpose of these two Concord addresses in some measure to remedy. That shortcoming was an imperfect appreciation of the goal toward which the process of evolution is tending, and a consequent failure to state adequately how the doctrine of evolution must affect our estimate of Man's place in Nature. Nothing of fundamental importance in "Cosmic Philosophy" needed changing, but a new chapter needed to be written, in order to show how the doctrine of evolution, by exhibiting the development of the highest spiritual human qualities as the goal toward which God's creative work has from the outset been tending, replaces Man in his old position of headship in the universe, even as in the days of Dante and Aquinas. That which the pre-Copernican astronomy naively thought to do by placing the home of Man in the centre of the physical universe, the Darwinian biology profoundly accomplishes by exhibiting Man as the terminal fact in that stupendous process of evolution whereby things have come to be what they are. In the deepest sense it is as true as it ever was held to be, that the world was made for Man, and that the bringing forth in him of those qualities which we call highest and holiest is the final cause of creation. The arguments upon which this conclusion rests, as they are set forth in the "Destiny of Man" and epitomized in the concluding section of the present essay, may all be found in "Cosmic Philosophy;" but I failed to sum them up there and indicate the conclusion, almost within reach, which I had not quite clearly seized. When, after long hovering in the background of consciousness, it suddenly flashed upon me two years ago, it came with such vividness as to seem like a revelation.
