These records inform us that, so far as men have paid attention to Nature, they have been rewarded for their pains.  They have developed the Arts which have furnished the conditions of civilised existence; and the Sciences, which have been a progressive revelation of reality, and have afforded the best discipline of the mind in the methods of discovering truth.  They have accumulated a vast body of universally accepted knowledge; and the conceptions of man and of society, of morals and of law, based upon that knowledge, are every day more and more, either openly or tacitly, acknowledged to be the foundations of right action.

History also tells us that the field of the supernatural has rewarded its cultivators with a harvest, perhaps not less luxuriant, but of a different character.  It has produced an almost infinite diversity of Religions.  These, if we set aside the ethical concomitants upon which natural knowledge also has a claim, are composed of information about Supernature; they tell us of the attributes of supernatural beings, of their relations with Nature, and of the operations by which their interference with the ordinary course of events can be secured or averted.  It does not appear, however, that supernaturalists have attained to any agreement about these matters or that history indicates a widening of the influence of supernaturalism on practice, with the onward flow of time.  On the contrary, the various religions are, to a great extent, mutually exclusive; and their adherents delight in charging each other, not merely with error, but with criminality, deserving and ensuing punishment of infinite severity.  In singular contrast with natural knowledge, again, the acquaintance of mankind with the supernatural appears the more extensive and the more exact, and the influence of supernatural doctrines upon conduct the greater, the further back we go in time and the lower the stage of civilisation submitted to investigation.  Historically, indeed, there would seem to be an inverse relation between supernatural and natural knowledge.  As the latter has widened, gained in precision and in trustworthiness, so has the former shrunk, grown vague and questionable; as the one has more and more filled the sphere of action, so has the other retreated into the region of meditation, or vanished behind the screen of mere verbal recognition.

Whether this difference of the fortunes of Naturalism and of Supernaturalism is an indication of the progress, or of the regress, of humanity; of a fall from, or an advance towards, the higher life; is a matter of opinion.  The point to which I wish to direct attention is that the difference exists and is making itself felt.  Men are growing to be seriously alive to the fact that the historical evolution of humanity which is generally, and I venture to think not unreasonably, regarded as progress, has been, and is being, accompanied by a co-ordinate elimination of the supernatural from its originally large occupation of men’s thoughts.  The question—­How far is this process to go?—­is in my apprehension, the Controverted Question of our time.
