In the Ascent of Man, Henry Drummond gives his take on Evolution. He sees evolution as divinely guided-- a position that made him no friends on either side of the debate. "'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."
