There will be few readers of this book who have not been brought up under the spell of some one of these systems of Supernaturalism; who have not been taught to speak with respect of some particular priestly order, to thrill with awe at some particular sacred rite, to seek respite from earthly woes in some particular ceremonial spell. These things are woven into our very fibre in childhood; they are sanctified by memories of joys and griefs, they are confused with spiritual struggles, they become part of all that is most vital in our lives. The reader who wishes to emancipate himself from their thrall will do well to begin with a study of the beliefs and practices of other sects than his own--a field where he is free to observe and examine without fear of sacrilege. Let him look into Madame Blavatsky's "Secret Doctrine", or her "Isis Unveiled"--encyclopedias of the fantastic inventions which terror and longing have wrung out of the tortured soul of man. Here are mysteries and solemnities, charms and spells, illuminations and transmigrations, angels and demons, guides, controls and masters--all of which it is permissible to refuse to support with gifts. Let the reader then go to James Freeman Clarke's "Ten Great Religions", and realize how many billions of humans have lived and died in the solemn certainty that their welfare on earth and in heaven depended upon their accepting certain ideas and practicing certain rites, all mutually exclusive and incompatible, each damning the others and the followers of the others. So gradually the realization will come to him that the test of a doctrine about life and its welfare must be something else than the fact that one was born to it. #The Great Fear# It was not the fault of primitive man that he was ignorant, nor that his ignorance made him a prey to dread. The traces of his mental suffering will inspire in us only pity and sympathy; for Nature is a grim school-mistress, and not all her lessons have yet been learned. We have a right to scorn and anger only when we see this dread being diverted from its true function, a stimulus to a search for knowledge, and made into a means of clamping down ignorance upon the mind of the race. That this has been the deliberate policy of institutionalized Religion no candid student can deny. The first thing brought forth by the study of any religion, ancient or modern, is that it is based upon Fear, born of it, fed by it--and that it cultivates the source from which its nourishment is derived. "The fear of divine anger", says Prof. Jastrow, "runs as an undercurrent through the entire religious literature of Babylonia and Assyria." In the words of Tabi-utul-Enlil, King of ancient Nippur: Who is there that can grasp the will of the gods in heaven? The plan of a god is full of mystery--who can understand it? He who is still alive at evening is dead the next morning. In an instant he is cast into grief, in a moment he is crushed.
