sack of black cloth, everywhere sewed tight by machine. Every crevice of the medium's body was searched before and after the tests, and every inch of the "cabinet" gone over. The investigators sat within a couple of feet of the medium, and would draw back the curtains, and while holding her hands and her feet, would watch great masses of filmy gray and white stuff exude from the medium's mouth, from her armpits and breasts and sides. This would happen in red light of a hundred candle power, by which print could be easily read; and the medium would herself illuminate the phenomena with a red electric torch. The investigators would be privileged to examine these "phantom" forms, to touch them gently, and be touched by them--soft and slimy, like the tongue of an animal; but sometimes the things would misbehave, and strike them in the eye, hurting them.The medium, a young French girl living in the home of the wife of a well-known French playwright, had begun with spiritualist ideas, but came to take a matter-of-fact attitude to what happened, and in her trances would labor to mold these emanations into hands or faces, as requested by those present. She finally succeeded in allowing them to separate the soft mucous stuff from her body, and keep it for chemical and bacteriological examination. All this time she would be surrounded by a battery of cameras, nine at once, some of them inside the cabinet; and when the desired emanation was in sight, all these cameras would be set off by flash-light, and in the book you have over two hundred such photographs, showing faces and hands from every point of view. There are even moving-pictures, showing the material coming out of her mouth and going back!
It is evident that we have here a whole universe of unexplored phenomena; and it seems that many of the oldtime superstitions which were dumped overboard have now to be dragged back into the boat and examined in the light of new knowledge. What could smack more of magic and fraud than crystal-gazing? Yet it appears that the subconsciousness has power to project an image of its hidden memories into a crystal ball, where it may be plainly seen. We find so well-recognized an authority as Dr. Morton Prince using this method to enable one of the many Miss Beauchamps to recall incidents in her previous life which were otherwise entirely lost
to her. Likewise this exploration of the disintegration of personality enables us to watch in the making all the phenomena of trance and ecstasy which have had so much to do with the making of religions. We know now how Joan of Arc heard the "voices," and
we can make her hear more voices or make her stop hearing voices, as we prefer. Also we know all about demons and "demoniac possession." We can cast out demons--and without having to cause them to enter a herd of swine! We may some day be prepared
to investigate the wonder stories which the Yogis tell us, about their ability to leave their physical bodies in a trance, and to appear in
England at a few moments' notice for the transaction of their spiritual business!
But we want things proven to us, and we don't want the people with whom we work to be animated either by religious fanaticism or by money greed. We are ready to unlimber our minds, and prepare for long journeys into strange regions, but we want to move cautiously, and choose our route carefully, and be sure we do not lose our way! We want to deal rationally with life; we don't want to make wild guesses, or to choose a complicated and unlikely solution when a simple one will suffice. But, on the other hand, we
must be alive to the danger of settling down on our little pile of knowledge, and refusing to take the trouble to investigate any more. That is a habit of learned men, I am sorry to say; the law of inertia applies to the scientist, as well as to the objects he studies. The scientists of our time have had to be prodded into considering each new discovery about the subconscious mind, precisely as the scientists of Galileo's time had to be prodded to watch him drop weights from the tower of Pisa. When he told them that the earth moved round the sun instead of the sun round the earth, they tortured him in a dungeon to make him take it back, and he did so,
32
but whispered to himself, "And yet it moves." And it did move, of course, and continued to move. And in exactly the same way, if it be true that we have these hidden forces in us, they will continue to manifest themselves, and masses of people will continue to flock to Lily Dale, and to pay out their hard-earned money, until such a time as our learned men set to work to find out the facts and tell us how we can utilize these forces without the aid of either superstition or charlatanry.
CHAPTER XVI
THE POWERS OF THE MIND
(Sets forth the fact that knowledge is freedom and ignorance is slavery, and what science means to the people.)
We have now completed a brief survey of the mind and its powers. Whatever we may have proved or failed to prove, this much we may say with assurance: the reader who has followed our brief sketch attentively has been disabused of any idea he may have held that he knows it all; and this is always the first step towards knowledge.
The mind is the instrument whereby our race has lifted itself out of beasthood. It is the instrument whereby we hold ourselves
above the forces which seek to drag us down, and whereby we shall lift ourselves higher, if higher we are to go. How shall we protect this precious instrument? How shall we complete our mastery of it? What are the laws of the conduct of the mind?
The process of the mind is one of groping outward after new facts, and digesting and assimilating them, as the body gropes after and digests and assimilates food. The senses bring us new impressions, and we take these and analyze them, tear them into the parts which compose them, compare them with previous sensations, recognize difference in things which seem to be alike, and resem-blances in things which seem to be different; we classify them, and provide them with names, which are, as it were, handles for the mind to grasp. Above all, we seek for causes; those chains of events which make what we know as order in the world of phenomena. And when the mind has what seems to be a cause, it proceeds to test it according to methods it has worked out, the rules and principles of experimental science.
It is a comparatively small number of sensations which the body brings to the mind of itself; it is a narrow world in which we should live if our minds adopted a passive attitude toward life. But some minds possess what we call curiosity; they set out upon their own impulse to explore life; they discover new laws and make new experiences and new sensations for themselves. The mind forms an idea, and at first, after the fashion of the ancient Greek philosophers, it glorifies that idea and sets it in the seat of divinity. But presently comes the empirical method, which refuses authority to any idea unless it can stand the test of experiment, and prove that it corresponds with reality. Nowadays the thinker amasses his facts, and forms a theory to explain them, and then proceeds to try out this theory by the most rigid method that he or his critics can devise. If the theory doesn't "work"--that is, if it doesn't explain all
the facts and stand all the tests--it is thrown away like a worn-out shoe. So little by little a body of knowledge is built up which is real knowledge; which will serve us in our daily lives, which we can use as foundation-stones in the structure of our civilization. By this method of research man is expanding his universe beyond anything that could have been conceived in the pre-scientific days. Hour by hour, while we work and play and sleep, the mind of our race is discovering new worlds in which our posterity will
dwell. For uncounted ages man walked upon the earth, surrounded by infinite swarms of bacterial life of whose existence he never dreamed. The invisible rays of the spectrum beat upon him, and he knew nothing of what they did to him, whether good or evil. He lifted his head and saw vast universes of suns, in comparison with which his world was a mere speck of dust; yet to him these universes were globes or lanterns which some divinity had hung in the sky.
One of the most fascinating illustrations of how the mind runs ahead of the senses is the story of the planet Uranus, which, less than two hundred years ago, had never been beheld by the eye of man. A mathematician seated in his
