+83. Inertia and rigidity of the mores.+ We see that we must conceive of the mores as a vast system of usages, covering the whole of life, and serving all its interests; also containing in themselves their own justification by tradition and use and wont, and approved by mystic sanctions until, by rational reflection, they develop their own philosophical and ethical generalizations, which are elevated into "principles" of truth and right. They coerce and restrict the newborn generation. They do not stimulate to thought, but the contrary. The thinking is already done and is embodied in the mores. They never contain any provision for their own amendment. They are not questions, but answers, to the problem of life. They present themselves as final and unchangeable, because they present answers which are offered as "the truth." No world philosophy, until the modern scientific world philosophy, and that only within a generation or two, has ever presented itself as perhaps transitory, certainly incomplete, and liable to be set aside to-morrow by more knowledge. No popular world philosophy or life policy ever can present itself in that light. It would cost too great a mental strain. All the groups whose mores we consider far inferior to our own are quite as well satisfied with theirs as we are with ours. The goodness or badness of mores consists entirely in their adjustment to the life conditions and the interests of the time and place (sec. 65). Therefore it is a sign of ease and welfare when no thought is given to the mores, but all cooperate in them instinctively. The nations of southeastern Asia show us the persistency of the mores, when the element of stability and rigidity in them becomes predominant. Ghost fear and ancestor worship tend to establish the persistency of the mores by dogmatic authority, strict taboo, and weighty sanctions. The mores then lose their naturalness and vitality. They are stereotyped. They lose all relation to expediency. They become an end in themselves. They are imposed by imperative authority without regard to interests or conditions (caste, child marriage, widows). When any society falls under the dominion of this disease in the mores it must disintegrate before it can live again. In that diseased state of the mores all learning consists in committing to memory the words of the sages of the past who established the formulae of the mores. Such words are "sacred writings," a sentence of which is a rule of conduct to be obeyed quite independently of present interests, or of any rational considerations.
