"fantastic tricks" which those who reject the supernatural are driven to play in their attempts to provide the world with a substitute. But every general event must have a general cause, for which individuals are not alone responsible; and the fantastic tricks of the people who try to make religions for themselves cannot be due merely to the idiosyncrasies of exceptionally foolish persons. There must be causes at the back of them of a deeper and a wider kind. The first of these causes is obviously the fact that, for some reason or other, multitudes who know nothing of one another are independently coming to the conclusion that supernaturalism, which was once accepted without question as the main content or substratum of human life, rests on postulates which to them are no longer credible. Why is this the case to-day, when it was not the case yesterday? Of these necessary postulates two are the same for all men--namely, an individual life which survives, the individual body, and the moral responsibility of the individual, or his possession of a free will. A third postulate, which is the same for all orthodox Christians, is the miraculous inspiration of the Bible, whatever the precise nature of this inspiration may be. Of these three postulates the last has been discredited all over the world by biblical criticism and scientific comparisons of one religion with another. The first and the second have been discredited by advances in the science of biological physics which has, with increasing precision, exhibited human life and thought as mere functions of the physical organism, the organism itself being, in turn, a part of the cosmic process. If this be the case, what religious significance can attach to the individual as such? His thoughts, his emotions, his actions, are no more his own than the action of a windmill's sails or the antics of scraps of paper gyrating at a windy corner.[3] The first license to men to construct a religion is a license given them by reason to admit the proposition that the individual will is free. The primary obstacle to religious belief to-day is the difficulty of finding in this universe a rational place for freedom--a "_voluntas avolsa fatis_." How is this obstacle to be surmounted? To this question I attempted an answer in a new philosophical book, _Religion as a Credible Doctrine_, of which the general contention is as follows. If we trust solely to science and objective evidence, the difficulty in question is insuperable. There is no place for individual freedom in the universe, and apologists who attempt to find one are no better than clowns tumbling in the dust of a circus. If they try to smuggle it in through some chink in the _moenia mundi_, these ageless walls are impregnable, or if here and there some semblance of a gate presents itself, each gate is guarded, like Eden, by science with its flaming swords.
