The reasons for the downfall of the Magical View are familiar. It seems to have arisen as a consequence of an increase in man’s knowledge of and command over nature (the discovery of agriculture). It fell through the extension of that knowledge of and command over nature. Throughout its (10,000 years?) reign its stability has been due to its capacity for satisfying men’s emotional needs through its adequacy as an object for their attitudes. We must remember that human attitudes have developed always _inside_ the social group; they are what a man feels, the mainsprings of his behaviour towards his fellow-men, and they have only a limited field of applicability. Thus the Magical View, being an interpretation of nature in terms of man’s own most intimate and most important affairs, very soon came to suit man’s emotional make-up better than any other view possibly could. The attraction of the Magical View lay very little in the actual command over nature which it gave. That Galton was the first person to test the efficacy of prayer experimentally is an indication of this. What did give the Magical View its standing was the ease and adequacy with which the universe therein presented could be emotionally handled, the scope offered for man’s love and hatred, for his terror as well as for his hope and his despair. It gave life a shape, a sharpness, and a coherence that no other means could so easily secure. In its place we have the universe of the mathematician, a field for the tracing out of ever wider and more general uniformities. A field in which intellectual certainty is, almost for the first time, available, and on an unlimited scale. Also the despondencies, the emotional excitements accompanying research and discovery, again on an unprecedented scale. Thus a number of men who might in other times have been poets are to-day in bio-chemical laboratories--a fact of which we might avail ourselves, did we feel the need, in defence of an alleged present poverty in poetry. But apart from these thrills, what has the world-picture of science to do with human emotions? A god voluntarily or involuntarily subject to the General Theory of Relativity does not make an emotional appeal. So this form of compromise fails. Various emergent deities have been suggested--by Mr. Wells, by Professors Alexander and Lloyd Morgan--but, alas! the reasons for suggesting them have become too clear and conscious. They are there to meet a demand, not to make one; they do not do the work for which they were invented. The revolution brought about by science is, in short, too drastic to be met by any such half-measures. It touches the central principle by which the Mind has been deliberately organized in the past, and no alteration in beliefs, however great, will restore equilibrium while that principle is retained. I come now to the main purport of these remarks.
