Mohammedanism, Romanism, and Protestantism contain Systems of world-philosophy which have been deduced from religious dogmas. The world-philosophy is in each case removed by several steps of deduction from the religious postulates. In each case Customs have grown up from the unavoidable compromise between metaphysical dogmas and interests, and these customs, so far as they inhere in essential traits of human nature, or in fundamental conditions of human life, or as far as they have taken on the sanctity of wide and ancient authority so that they seem to be above discussion, are the mores. Does a Roman Catholic, or a Mohammedan, or a Protestant child begin by learning the dogmas of his religion and then build a life-code on them? Not at all. He begins by living in, and according to, the mores of his family and societal environment. The vast mass of men in each case never do anything else but thus imbibe a character from the environment. If they learn the religious dogmas at all, it is superficially, negligently, erroneously. They are trained in the ritual, habituated to the usages, imbued with the notions, of the societal environment. They hear and repeat the proverbs, sayings, and maxims which are current in it. They perceive what is admired, ridiculed, abominated, desired by the people about them. They learn the code of conduct—what is considered stupid, smart, stylish, clever, or foolish, and they form themselves on these ideas. They get their standards from the standards of their environment. Behind this, but far behind it for all but the scholars, are the history and logic by which the mores are connected with the religious facts or dogmas, and when the scholars investigate the history and logic they find that the supposed history is a tissue of myths and legends and that the logic is like a thread broken at a hundred points, twisted into innumerable windings, and snarled into innumerable knots.
