As for the theories that attempt to explain it, I am quite willing to grant that they are still somewhat confused. The important thing for the moment is the accumulation of claims and experiments that go feeling their way farther and farther along all the paths of the unknown. Meanwhile, that one unexpected door which sheds at the back of our old convictions more than one unexpected door, which sheds upon the life and habits of our secret being sufficient light to puzzle us for many a long day. This brings us back once more to the omniscience and perhaps the omnipotence of our hidden guest, to the brink of the mysterious reservoir of every manner of knowledge which we shall meet with again when we come to speak of the future, of the talking horses, of the divining-rod, of materializations and miracles, in short, in every circumstance where we pass beyond the horizon of our little daily life. As we thus advance, with slow and cautious footsteps, in them as yet deserted and very nebulous regions of metapsychics, we are compelled to recognize that there must exist somewhere, in this world or in others, a spot in which everything is known, in which everything is possible, to which everything goes, from which everything comes, which belongs to all, to which all have access, but of which the long-forgotten roads must be learnt again by our stumbling feet. We shall often meet those difficult roads in the course of our present quest and we shall have more than one occasion to refer again to those depths into which all the supernatural facts of our existence flow, unless indeed they take their source there. For the moment, that which most above all engage our attention in these psychometric phenomena is their purely and exclusively human character. They occur between the living and the living, on this solid earth of ours, in the world that lies before our eyes; and the spirits, the dead, the gods and the interplanetary intelligences know them not. Hardly anywhere else, except in the equally perplexing manifestations of the divining-rod and in certain materializations, shall we find with the same clearness this same specific character, if we may call it so. This is a valuable lesson. It tells us that our every-day life provides phenomena as disturbing and of exactly the same kind and nature as those which, in other circumstances, we attribute to other forces than ours. It teaches us also that we must first direct and exhaust our enquiries here below, among ourselves, before passing to the other side; for our first care should be to simplify the interpretations and explanations and not to seek elsewhere, in opposition, what probably lies hidden within us in reality. Afterwards, if the unknown overwhelm us utterly, if the darkness engulf us beyond all hope, there will still be time to go, none can tell where, to question the deities or the dead. CHAPTER III.
