Yet what is hysteria and what does it really explain? [1] Surely the etymology throws no light on the subject! Is it then merely a name for the unknown cause of phenomena every whit as strange as those which were held incredible till their like had been actually witnessed and forced upon the unwilling eyes of science beyond all possibility of denial? Is it that science blindly refused even to weigh the evidence for abnormal facts till the same or similar had become matters of personal observation? Is it that every reported breach of her assumed uniformities is incredible, because impossible, until the possibility has been proved by some fact which is then named, erected into a class, a cause, a law, and used to explain away similar facts formerly denied, and is thus taken into that bundle of generalizations called the "laws of nature"? The ancients assumed all heavenly motion to be circular of necessity, and where facts gave against them, they patched the matter up with an epicycle or two. Are not hysteria, hypnotism, and thought-transference of the nature of epicycles? It is now confessed that the mind can so affect and dominate the body as to produce blisters and wounds by mere force of suggestion and expectancy; that a like "faith" can cure, not only such ailments as are clearly connected with the nerves, but others where such connection is not yet traceable. And this is supposed to tell in some way against like marvels reported by hagiology, as though they were explained by being observed and named. Yet what did that supposed marvellousness consist in, except in a seeming revelation of the power and superiority of mind over matter, and of things unseen over things seen and palpable; and in proving that there were more wonders in heaven and earth than were dreamt of by a crude and self-satisfied materialism? They were taken as evidence of a circumambient X-region where the laws of mechanics were set at defiance and where the fetters of time and place were loosened or cast aside. Such an X-region being supposed by every supernatural religion and denied by most of those who deny religion, and on the same grounds, its establishment by any kind of experiment is rightly considered in some sort to make for religion. Indeed, it is just on this account that the evidence for it is so opposed by those who are pre-occupied by the anti-religious bias of contemporary science. But unless hysterical effects can be shown to be ultimately due, not to mind, but to matter acting on matter, according to methods approved by materialism, hysteria remains a word-cause and no more, like the meat-cooking quality of the roasting-jack.
