“The more I think of it,” says Mr. Ruskin, “I find this conclusion more impressed upon me—that the greatest thing a human soul ever does in this world is to see something, and tell what it saw in a plain way.” In these pages an attempt is made to tell “in a plain way” a few of the things which Science is now seeing with regard to the Ascent of Man. Whether these seeings are there at all is another matter. But, even if visions, every thinking mind, through whatever medium, should look at them. What Science has to say about himself is of transcendent interest to Man, and the practical bearings of this theme are coming to be more vital than any on the field of knowledge. The thread which binds the facts is, it is true, but a hypothesis. As the theory, nevertheless, with which at present all scientific work is being done, it is assumed in every page that follows.

Though its stand-point is Evolution and its subject Man, this book is far from being designed to prove that Man has relations, compromising or otherwise, with lower animals. Its theme is Ascent, not Descent. It is a History, not an Argument. And Evolution, in the narrow sense in which it is often used when applied to Man, plays little part in the drama outlined here.
