Medicine, like other natural phenomena tends to the cyclic. Having passed safely through the drug period of evolution, both allopathic and homeopathic, into the no-drug state of so-called "preventive medicine" which has nothing to do with medicine as the word is commonly understood, this ancient mystery of the cure of bodies is now reunited to its equally ancient but long alienated mate the cure of souls, and this bewildered generation is confronted with the amazing spectacle of the lion of science and the lamb of religion lying down together. Whether the ultimate resting place of the lamb will be inside the lion is not yet disclosed to the anxious and inquiring mind. Again the priest and the physician are combined in one person, and we see before us the modern counterpart of the antique medicine man who exorcised the devils that possessed and tormented the soul and the body, and by sorcery and incantations treated impartially diseases of the spirit and of the flesh. Again the accepted cure for blindness is to "go and sin no more." It is especially that borderland where soul and body meet and fuse in what a recent treatise on the diseases of the nervous system calls "the psychic or symbolic system" that the modern medicine man takes as his province. In this No Man's Land he is master of all he surveys, and his sextant comprises the universe in its angle. We are prone to think of diseases of the mind as a specialty of modern life. But the briefest review of history would indicate that these symptoms of maladjustment to the environment have been evident from the earliest times. Adam and Eve are said to have developed "paranoiac delusions of persecution," a kind of _manie à deux_, accompanied by hallucinations of vision described as "seeing snakes." Their elder son was afflicted with a "homicidal mania," while the younger was apparently a case of "constitutional inferiority." Noah was a well recognized "alcoholic," Job was subject to severe "depressions," Nebuchadnezzar exhibited "praecox dilapidations of conduct" and Saul was a pronounced "manic-depressive." The Bible contains many edifying and well worked-out case histories with prescriptions for the treatment of such difficulties. It was Isaiah who outlined the newer method when he said, on the highest authority, "Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow." It was perhaps through dwelling on his own race history and literature that the newest prophet in Israel, the famous, to some infamous, Viennese professor, Sigmund Freud, came to invent the latest prophylaxis for mental disorders, now widely known under the name of psychoanalysis, at present the best recognized specific for many mental disorders, and particularly for those orgies and "hang-overs" of the soul, the "manic-depressive psychosis."
