“When I first undertook,” says William James, “to collate this series of sittings and make the present report, I supposed that my verdict would be determined by pure logic. Certain minute incidents, I thought, ought to make for spirit-return or against it in a ‘crucial’ way. But watching my mind work as it goes over the data, convinces me that exact logic plays only a preparatory part in shaping our conclusions here; and that the decisive vote, if there be one, has to be cast by what I may call one’s general sense of dramatic probability, which sense ebbs and flows from one hypothesis to another—it does so in the present writer at least—in a rather illogical manner. If one sticks to the detail, one may draw an anti-spiritist conclusion; if one thinks more of what the whole mass may signify, one may well incline to spiritist interpretations.”[5] And, at the end of his article, he sums up in the following words: “_I myself feel as if an external will to communicate were probably there_, that is, I find myself doubting, in consequence of my whole acquaintance with that sphere of phenomena, that Mrs. Piper’s dream-life, even equipped with ‘telepathic’ powers, accounts for all the results found. But if asked whether the will to communicate be Hodgson’s, or be some mere spirit-counterfeit of Hodgson, I remain uncertain and await more facts, facts which may not point clearly to a conclusion for fifty or a hundred years.”[6] As we see, William James is inclined to waver; and at certain points in his account he appears to waver still more and indeed to say deliberately that the spirits “have a finger in the pie.” These hesitations on the part of a man who has revolutionized our psychological ideas and who possessed a brain as wonderfully organized and well-balanced as that of our own Taine, for instance, are very significant. As a doctor of medicine and a professor of philosophy, sceptical by nature and scrupulously faithful to experimental methods, he was thrice qualified to conduct investigations of this kind to a successful conclusion. It is not a question of allowing ourselves, in our turn, to be unduly influenced by those hesitations; but, in any case, they show that the problem is a serious one, the gravest, perhaps, if the facts were beyond dispute, which we have had to solve since the coming of Christ; and that we must not expect to dismiss it with a shrug or a laugh. 6
