Four thousand years have passed since houses were haunted in Egypt, and have left some sane, educated, and methodical men to meet the same annoyances as the ancient Egyptians did, by the same measures. We do not pretend to discover, without examination, the causes of the sounds and sights which baffle trained and not superstitious investigators. But we do say that similar occurrences, in a kraal or an Eskimo hut, in a wigwam, in a cave, or under a gunyeh, would greatly confirm the animistic hypothesis of savages. The theory of imposture (in some cases) does undeniably break down, for the people who hold it cannot even suggest a modus operandi within the reach of the human beings concerned, as in the case of the Wesleys. The theory of contagious hallucination of all the senses is the property of Coleridge alone. The hypothesis of a nervous force which sets up centres of conscious action is confined to Hartmann, and to certain Highland philosophers, cavalierly dismissed by the Rev. Robert Kirk as 'men illiterate'. Instead of making these guesses, the savage thinkers merely applied the animistic hypothesis, which they had found to work very well already, and, as De Morgan says, to colligate the phenomena better than any other theory. We cannot easily conceive men who know neither sleep nor dreams, but if the normal phenomena of sleep and dreams had not existed, the abnormal phenomena already described, if they occurred, as they are universally said to do, could have given rise, when speculated upon, to the belief in spirits. But, it may reasonably be urged, 'the natural familiar facts of life, death, sleep, waking, dreams, breath, and shadows, are all versae causae, do undeniably exist, and, without the aid of any of your abnormal facts, afford basis enough for the animistic hypothesis. Moreover, after countless thousands of years, during which superstition has muttered about your abnormal facts, official science still declines to hear a word on the topic of clairvoyance or telepathy. You don't find the Royal Society investigating second sight, or attending to legends about tables which rebel against the law of gravitation.' These are cogent remarks. Normal facts, perhaps, may have suggested the belief in spirits, the animistic hypothesis. But we do not find the hypothesis (among the backward races) where abnormal facts are not alleged to be matters of comparatively frequent experience. Consequently we do not _know_ that the normal facts, alone, suggested the existence of spirits to early thinkers, we can only make the statement on a priori grounds. Like George Eliot's rural sage we 'think it sounds a deal likelier'. But that, after all, though a taking, is not a powerful and conclusive syllogism.
