Dogmatically to decide this is an impossible task. Not only are the other sciences and the philosophy still far from being completed, but in their present state we find them full of conflicts. The sciences of nature know nothing of spiritual presences, and on the whole hold no practical commerce whatever with the idealistic conceptions towards which general philosophy inclines. The so-called scientist is, during his scientific hours at least, so materialistic that one may well say that on the whole the influence of science goes against the notion that religion should be recognized at all. And this antipathy to religion finds an echo within the very science of religions itself. The cultivator of this science has to become acquainted with so many groveling and horrible superstitions that a presumption easily arises in his mind that any belief that is religious probably is false. In the 'prayerful communion' of savages with such mumbo-jumbos of deities as they acknowledge, it is hard for us to see what genuine spiritual work—even though it were work relative only to their dark savage obligations—can possibly be done.
The consequence is that the conclusions of the science of religions are as likely to be adverse as they are to be favorable to the claim that the essence of religion is true. There is a notion in the air about us that religion is probably only an anachronism, a case of 'survival,' an atavistic relapse into a mode of thought which humanity in its more enlightened examples has outgrown; and this notion our religious anthropologists at present do little to counteract.
This view is so widespread at the present day that I must consider it with some explicitness before I pass to my own conclusions. Let me call it the 'Survival theory,' for brevity's sake.
