Superstition recurs in all ages, and especially in rationalistic ages. I remember defending the religious tradition against a whole luncheon-table of distinguished agnostics; and before the end of our conversation every one of them had procured from his pocket, or exhibited on his watch-chain, some charm or talisman from which he admitted that he was never separated. I was the only person present who had neglected to provide himself with a fetish. Superstition recurs in a rationalist age because it rests on something which, if not identical with rationalism, is not unconnected with scepticism. It is at least very closely connected with agnosticism. It rests on something that is really a very human and intelligible sentiment, like the local invocations of the numen in popular paganism. But it is an agnostic sentiment, for it rests on two feelings: first that we do not really know the laws of the universe; and second that they may be very different from all that we call reason. Such men realise the real truth that enormous things do often turn upon tiny things. When a whisper comes, from tradition or whatnot, that one particular tiny thing is the key or clue, something deep and not altogether senseless in human nature tells them that it is not unlikely. This feeling exists in both the forms of paganism here under consideration. But when we come to the second form of it, we find it transformed and filled with another and more terrible spirit.
In dealing with the lighter thing called mythology, I have said little about the most disputable aspect of it; the extent to which such invocation of the spirits of the sea or the elements can indeed call spirits from the vasty deep; or rather (as the Shakespearean scoffer put it) whether the spirits come when they are called. I believe that I am right in thinking that this problem, practical as it sounds, did not play a dominant part in the poetical business of mythology. But I think it even more obvious, on the evidence, that things of that sort have sometimes appeared, even if they were only appearances. But when we come to the world of superstition, in a more subtle sense, there is a shade of difference; a deepening and a darkening shade. Doubtless most popular superstition is as frivolous as any popular mythology. Men do not believe as a dogma that God would throw a thunderbolt at them for walking under a ladder; more often they amuse themselves with the not very laborious exercise of walking round it. There is no more in it than what I have already adumbrated; a sort of airy agnosticism about the possibilities of so strange a world. But there is another sort of superstition that does definitely look for results; what might be called a realistic superstition. And with that the question of whether spirits do answer or do appear becomes much more serious. As I have said, it seems to me pretty certain that they sometimes do; but about that there is a distinction that has been the beginning of much evil in the world.
Whether it be because the Fall has really brought men nearer to less desirable neighbours in the spiritual world, or whether it is merely that the mood of men eager or greedy finds it easier to imagine evil, I believe that the black magic of witchcraft has been much more practical and much less poetical than the white magic of mythology. I fancy the garden of the witch has been kept much more carefully than the woodland of the nymph. I fancy the evil field has even been more fruitful than the good. To start with, some impulse, perhaps a sort of desperate impulse, drove men to the darker powers when dealing with practical problems. There was a sort of secret and perverse feeling that the darker powers would really do things; that they had no nonsense about them. And indeed that popular phrase exactly expresses the point. The gods of mere mythology had a great deal of nonsense about them. They had a great deal of good nonsense about them; in the happy and hilarious sense in which we talk of the nonsense of Jabberwocky or the Land where the Jumblies live. But the man consulting a demon felt as many a man has felt in consulting a detective, especially a private detective: that it was dirty work but the work would really be done. A man did not exactly go into the wood to meet a nymph; he rather went with the hope of meeting a nymph. It was an adventure rather than an assignation. But the devil really kept his appointments and even in one sense kept his promises; even if a man sometimes wished afterwards, like Macbeth, that he had broken them.
In the accounts given us of many rude or savage races we gather that the cult of demons often came after the cult of deities, and even after the cult of one single and supreme deity. It may be suspected that in almost all such places the higher deity is felt
