"If the anthropoid ape does not possess reason as we possess it, it cannot be said that on our rational side we are his progeny," says Dr. Adler: But, suppose we were to say that if our remote African or Australian savage ancestors did not possess reason as we possess it, "it cannot be said that on our rational side we are their progeny," The child in the cradle does not possess reason "as we do," any more than does the anthropoid ape, but the beginnings of reason are in both. Let the worm climb and he will overtake man. This is a most hopeful, a most beautiful gospel. Its spirit is not one of isolation and exclusiveness from the rest of nature, but one of fellowship and sympathy. We are all--plants, trees, birds, bugs, animals--all members of one family, children at various ages and stages of growth of the same great mother,--Nature. We quote again: "When I ask him (Metchnikoff) whence do I come, he points to the simian stage which we have left behind; but I would look beyond that stage to some ultimate fount of being, to which all that is highest in me and in the world around me can be traced, a source of things equal to the best that I can conceive." But if there is "some ultimate fount of being," to which our "highest" nature "can be traced," whence did our lower nature come? Is Prof. Adler trying to say God? We do not object to the word, we only ask that he give the word a more intelligible meaning than has yet been given. If God is the "ultimate fount of being to which all that is highest in us can be traced," who or what is the ultimate fount to which all that is lowest in us can be traced? Let us have the names of the two ultimate founts of being, and also to what still more ultimate founts _these_ founts may be traced. In our opinion Dr. Adler has failed to do justice to Prof. Metchnikoff. It is no answer to the Darwinian Theory, which the Russian scientist accepts in earnest, and in all its fullness,--not fractionally, as Adler seems to do--to say that it does not explain everything. No one claims that it does. Not all the mystery of life has been cleared. Evolution has offered us only a new key, so to speak, with which to attempt the doors which have not yielded to metaphysics. And if the key has not opened all the doors, it has opened many. Prof. Adler seems to think that the doctrine of evolution explains only the physical descent of man; for the genesis of the spiritual man, he looks for some supernatural "fount" in the skies. Well, that is not science; that is theology, and Adler's estimate of Jesus is just as theological as his criticism of evolution. APPENDIX
