It was predicted some years ago that the founder of the Ethical Societies will before long return to the Jewish faith of his fathers. However this may be, we have seen, in his estimate of Jesus and John Calvin, evidences of his estrangement from rationalism, of which in his younger days he was so able a champion. In his criticism of the Russian scientist, Metchnikoff, of the Pasteur Institute in Paris, Prof. Adler, endorsing the popular estimate of Jesus, accepts also the popular attitude toward science. He appears to prefer the doctrine of special creation to the theory of evolution. We would not have believed this of Felix Adler if we did not have the evidence before us. We speak of this to show the relation between an exaggerated praise of a popular idol, and a denial of the conclusions of modern science. It is the popular view which Prof. Adler champions in both instances. In his criticism of Metchnikoff's able book, _The Nature of Man,_ Prof. Adler writes: And to account for the reason in man, this divine spark that has been set ablaze in him, it is not sufficient to point to an ape as our ancestor. If we are descended from an anthropoid ape on the physical side, we are not descended from him in any strict sense of the word on our rational side; for as life is born of life, so reason is born of reason, and 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. If the above had been written fifty years ago, when the doctrine of evolution was a heresy, or by an orthodox clergyman of today, we would have taken no note of it. But coming as it does from the worthy founder of the Ethical Movement in America, it deserves attention. "If," says Dr. Adler, "we are descended from an anthropoid ape on the physical side, we are not descended from him in any strict sense of the word on our rational side." He is not sure, evidently, that even physically man is the successor of the anthropoid ape, but he is sure that "we are not descended from him...on our rational side." Is Dr. Adler, then, a dualist? Does he believe that there are two eternal sources, from one of which we get our bodies, and from the other our "rational side?" And why cannot Dr. Adler be a monist? He answers, "for as life is born of life, so reason is born of reason, and 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." Not so, good doctor! There is no life without reason. Do we mean to say that the jelly-fish, the creeping worm, or the bud on the tree has reason? Yes; not as much reason as a horse or a dog, and certainly not as much as a Metchnikoff or an Adler, but these lower forms of life could not have survived but for the element of rationality in them. We may call this instinct, sensation, promptings of nature, but what's in a name? The difference between a pump and a watch is only a difference of mechanism.
