Chapter I: Part II: ) on this subject--not, indeed, to discuss it fully (for this

would be impossible in the limits of a chapter), but to put the mind of the reader in position to understand it and to judge for himself.

Again: Every reader of the first edition must have remarked that there are many fundamental religious questions which I have not touched at all in Part III. I had avoided these because my own mind was not yet fully clear. I regarded what I then wrote as only a little leaven in a very large lump. I was willing to wait and let it work. In the mean time it has worked in my own mind, and I hope in the minds of others. I have therefore added two chapters to this part. In one I simply carry out to their logical consequences the doctrine of the Divine Immanency. This brings up the questions of _First and Second Causes_; of _General and Special Providence_; of the _Natural and the Supernatural_; of _Mind vs. Mechanics in Nature_, etc., and shows the necessary changes of view which are enforced by the theory of evolution.

In the other I take up very briefly “_The Relation of Evolution to the Doctrine of the Christ_.” In the discussion of this I restrain myself strictly within the limits of the subject as stated above.

The only other important changes are in Chapter IV, Part III, “_On the Relation of Man to Nature_.” As I regard this as the most important chapter in the whole book, I have endeavored still further to enforce my view of the origin of man’s spirit, and especially to make it clearer by means of several additional illustrations.
