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 The argument in this volume will be better understood if we give to our readers the comments and criticisms which our little pamphlet, _Jesus a Myth,_ and _The Mangasarian-Crapsey Debate on the Historicity of Jesus, _[Footnote: Price, 25c. Independent Religious Society, Orchestra Hall, Chicago.] called forth from orthodox and liberal clergymen. We shall present these together with our reply as they appeared on the Sunday Programs of the Independent Religious Society. Criticism is welcome. If the criticism is just, it prevents us from making the same mistake twice; if it is unjust, it gives us an opportunity to correct the error our critic has fallen into. No one's knowledge is perfect. But the question is, does a teacher suppress the facts? Does he insist on remaining ignorant of the facts? FROM THE SUNDAY PROGRAMS I Now that the debate on one of the most vital questions of modern religious thought--The Historicity of Jesus--is in print, a few further reflections on some minor points in Dr. Crapsey's argument may add to the value of the published copy. REV. DR. CRAPSEY: "Now, I say this is the great law of religious variation, that in almost every instance, indeed, I think, in every single instance in history, all such movements begin with a _single_ personality." (P. 5, _Mangasarian-Crapsey Debate._)
