It is probable that one of the factors that turned primitive man's attention away from his cruel and short, earthly existence to the thought of a more lengthy and less cruel existence in a hereafter, was the extreme uncertainty and short duration of his own life. And this primitive trend of thought that turns man's mind from the here and now to a contemplation of a mythical hereafter persists to this day, produces the same slavish resignation. This false release from the actualities constitute a mental aberration which we see in the hysterical and weak-minded. When such an individual is confronted by problems that tax his mental strength, if that individual has not strength of mind to reason and to persevere so that he overcomes his environmental difficulties, he will seek an avenue of escape in a fanciful existence which the physician recognizes in hysteria and certain forms of mental disease. So, throughout the ages, man has sought release from the realities of his existence into a fanciful and pleasantly delusional flight into a hereafter. "There is no salvation in that sickly obscurantism which attempts to evade realities by confusing itself about them. Safety lies only in clarity and the struggle for the light. No subliminal nor fringe of consciousness can rank in the intellectual life beside the burning focal center where the rays of knowledge converge. The hope must be in following reason, not in thwarting it. To turn back from it is not mysticism, it is superstition. No; we must be prepared to see the higher criticism destroy the historicity of the most sacred texts of the Bible, psychology analyze the phenomena of conversion on the basis of adolescent passion, anthropology explain the genesis of the very idea of God. An where _we_ can understand, it is a moral crime to cherish the un-understood. (_James T. Shotwell_: "_The Religious Revolution of Today._") Religious beliefs are clearly mental aberrations from which it is high time that the progress of knowledge should lead to a logical cure. Man is steadily overcoming and conquering his environment; the uncertainty of life and cruelty are much diminished as compared with the past ages, but man has not as yet fully utilized the means of an emancipating measure from his mental enslavement and fear of his environment."
