But these difficulties attend at all times the introduction of a new subject—or at least of one which is new to the generation concerned; and can of course not be allowed to interfere with the candid and impartial examination of the subject, or with the assimilation, as far as feasible, of its message. It should certainly, I think, be admitted that there are dangers attending the new science—or rather attending the hasty and careless investigation of it—just as there are attending any other science. There is no doubt that the phenomena connected with it are so astounding that they in some cases unhinge people’s minds, or at least for the time upset them; and what we have already said once or twice of the frequent bodily exhaustion of the Medium, not to mention the occasional exhaustion of the sitters, must convince us that the greatest care should be exercised in connection with trance-conditions, and that the whole subject should be studied with a view to discovering its proper and best handling. It is clear—whatever view is taken of the process—that a certain disintegration of the organism, and even of the personality of the medium, is liable to occur, one portion of the organism acting in a manner and under influences foreign to another portion, and that such disintegration oft repeated or long continued may be liable to produce a permanent degeneration of physique or even possibly demoralization of character. If there is a danger in this direction—and the extent of the danger should certainly be gauged—equally certainly it ought to be minimized or averted by the proper conditions. On the other hand, while noting this danger, we should not leave out of mind that some evidence points in the other direction—namely, to the favorable effects and influences of trance when rightly conducted.[84] We may also in this connection allude to the changed attitude of the general mind to-day toward Hypnotism—a subject allied to that which we are considering. Fifty years ago the word had a sinister sound, and hypnotism and mesmerism were thought to be inventions of the devil and agencies of all evil. To-day they are recognized as a great power for good, and in at least two hospitals (in France) as the main instrument of healing. Naturally, when people are ignorant of a subject, or only in the first stages of knowledge with regard to it, they mishandle and misunderstand it. It may well happen therefore that with better understanding of mediumship and trance-conditions, some of their drawbacks or less favorable aspects may pass out of sight.
