EXISTENCE, as we know it, is full of sorrow. To mention only one minor point: every man is a condemned criminal, only he does not know the date of his execution. This is unpleasant for every man. Consequently every man does everything possible to postpone the date, and would sacrifice anything that he has if he could reverse the sentence. Practically all religions and all philosophies have started thus crudely, by promising their adherents some such reward as immortality. No religion has failed hitherto by not promising enough; the present breaking up of all religions is due to the fact that people have asked to see the securities. Men have even renounced the important material advantages which a well-organized religion may confer upon a State, rather than acquiesce in fraud or falsehood, or even in any system which, if not proved guilty, is at least unable to demonstrate its innocence. Being more or less bankrupt, the best thing that we can do is to attack the problem afresh without preconceived ideas. Let us begin by doubting every statement. Let us find a way of subjecting every statement to the test of experiment. Is there any truth at all in the claims of various religions? Let us examine the question. Our original difficulty will be due to the enormous wealth of our material. To enter into a critical examination of all systems would be an unending task; the cloud of witnesses is too great. Now each religion is equally positive; and each demands faith. This we refuse in the absence of positive proof. But we may usefully inquire whether there is not any one thing upon which all religions have agreed: for, if so, it seems possible that it may be worthy of really thorough consideration. It is certainly not to be found in dogma. Even so simple an idea as that of a supreme and eternal being is denied by a third of the human race. Legends of miracle are perhaps universal, but these, in the absence of demonstrative proof, are repugnant to common sense. But what of the origin of religions? How is it that unproved assertion has so frequently compelled the assent of all classes of mankind? Is not this a miracle? There is, however, one form of miracle which certainly happens, the influence of the genius. There is no known analogy in Nature. One cannot even think of a "super-dog" transforming the world of dogs, whereas in the history of mankind this happens with regularity and frequency. Now here are three "super-men," all at loggerheads. What is there in common between Christ, Buddha, and Mohammed?
