(M140) It seems not improbable that in our own rules of conduct, in what we call the common decencies of life as well as in the weightier matters of morality, there may survive not a few old savage taboos which, masquerading as an expression of the divine will or draped in the flowing robes of a false philosophy, have maintained their credit long after the crude ideas out of which they sprang have been discarded by the progress of thought and knowledge; while on the other hand many ethical precepts and social laws, which now rest firmly on a solid basis of utility, may at first have drawn some portion of their sanctity from the same ancient system of superstition. For example, we can hardly doubt that in primitive society the crime of murder derived much of its horror from a fear of the angry ghost of the murdered man. Thus superstition may serve as a convenient crutch to morality till she is strong enough to throw away the crutch and walk alone. To judge by the legislation of the Pentateuch the ancient Semites appear to have passed through a course of moral evolution not unlike that which we can still detect in process among the Esquimaux of Baffin Land. Some of the old laws of Israel are clearly savage taboos of a familiar type thinly disguised as commands of the deity. This disguise is indeed a good deal more perfect in Palestine than in Baffin Land, but in substance it is the same. Among the Esquimaux it is the will of Sedna; among the Israelites it is the will of Jehovah.(690) But it is time to return to our immediate subject, to wit, the rules of conduct observed by hunters after the slaughter of the game.
