That there should exist one other person in the world towards whom all openness of interchange should establish itself, from whom there should be no concealment; whose body should be as dear to one, in every part, as one's own; with whom there should be no sense of Mine or Thine, in property or possession; into whose mind one's thoughts should naturally flow, as it were to know themselves and to receive a new illumination; and between whom and oneself there should be a spontaneous rebound of sympathy in all the joys and sorrows and experiences of life; such is perhaps one of the dearest wishes of the soul.--"Love's Coming of Age." It may chance that someone into whose hands this book falls may protest that he or she has never felt the fundamental yearning to form a part of that trinity which alone is the perfect expression of humanity. If that is so, it is possible that all unconsciously he may be suffering from a real malady--sex anæsthesia. This is the name given to an inherent coldness, which, while it lacks the usual human impulse of tenderness, is generally quite unconscious of its lack. It may even be that the reader's departure from the ordinary ranks of mankind is still more fundamental, in which case, instead of sitting in judgment on the majority, he will do well to read some such book as "The Sexual Question" (English translation 1908) by the famous Professor August Forel, in order that his own nature may be made known to him. He may then discover to which type of our widely various humanity he belongs. He need not read my book, for it is written about, and it is written for, ordinary men and women who, feeling themselves incomplete, yearn for a union that will have power not only to make a fuller and richer thing of their own lives, but which will place them in a position to use their sacred trust as creators of lives to come. It has happened many times in human history that individuals have not only been able to conquer this natural craving for a mate, but have set up celibacy as a higher ideal. In its most beautiful expression and sublimest manifestations, the celibate ideal has proclaimed a world-wide love, in place of the narrower human love of home and children. Many saints and sages, reformers and dogmatists have modelled their lives on this ideal. But such individuals cannot be taken as the standard of the _race_, for they are out of its main current: they are branches which may flower, but never fruit in a bodily form. In this world our spirits not only permeate matter but find their only expression through its medium. So long as we are human we must have bodies, and bodies obey chemical and physiological, as well as spiritual laws. If our race as a whole set out to pursue an ideal which must ultimately eliminate bodies altogether, it is clear that very soon we should find the conditions of our environment so altered that we could no longer speak of the human race.
