Before proceeding to a statement of the evidence which has convinced the more educated and more skeptical converts, let us consider briefly the bearing of the undoubted fact, that (to keep within bounds) many thousands of well-informed men, belonging to all classes of society and all professions, have, in each of the great civilized nations of the world, acknowledged the objective reality of these phenomena; although, almost without exception, they at first viewed them with dislike or contempt, as impostures or delusions. There is nothing parallel to it in the history of human thought; because there never before existed so strong and apparently so well-founded a conviction that phenomena of this kind never have happened and never can happen. It is often said, that the number of adherents to a belief is no proof of its truth. This remark justly applies to most religions whose arguments appeal to the emotions and the intellect but not to the evidence of the senses. It is equally just as applied to a great part of modern science. The almost universal belief in gravitation, and in the undulatory theory of light, does not render them in any degree more probable; because very few indeed of the believers have tested the facts which most convincingly demonstrate those theories, or are able to follow out the reasoning by which they are demonstrated. It is for the most part a blind belief accepted upon authority. But with these spiritual phenomena the case is very different. They are to most men so new, so strange, so incredible, so opposed to their whole habit of thought, so apparently opposed to the pervading scientific spirit of the age, that they cannot and do not accept them on second-hand evidence, as they do almost every other kind of knowledge. The thousands or millions of Spiritualists, therefore, represent to a very large extent men who have witnessed, examined, and tested the evidence for themselves, over and over and over again, till that which they had at first been unable to admit _could_ be true, they have at last been compelled to acknowledge _is_ true. This accounts for the utter failure of all the attempted “exposures” and “explanations” to convince one solitary believer of his error. The exposers and explainers have never got beyond those first difficulties which constitute the _pons asinorum_ of Spiritualism, which every believer has to get over, but at which early stage of investigation no converts are ever made. By explaining table-turning, or table-tilting, or raps, you do not influence a man who was never convinced by these, but who, in broad daylight, sees objects move without contact, and behave as if guided by intelligent beings; and who sees this in a variety of forms, in a variety of places, and under such varied and stringent conditions, as to make the fact to him just as real as the movement of iron to the magnet. By explaining automatic writing (which itself convinces no one but the
