And it may be that a great number of the very curious and seemingly senseless taboos that we find among the primitive peoples can be partly explained in this way: that is, that by ruling out certain directions of activity they enabled people to concentrate more effectually, for the time being, on other directions. To primitive folk the great world, whose ways are puzzling enough in all conscience to us, must have been simply bewildering in its dangers and complications. It was an amazement of Fear and Ignorance. Thunderbolts might come at any moment out of the blue sky, or a demon out of an old tree trunk, or a devastating plague out of a bad smell--or apparently even out of nothing at all! Under those circumstances it was perhaps wise, wherever there was the smallest SUSPICION of danger or ill-luck, to create a hard and fast TABOO--just as we tell our children ON NO ACCOUNT to walk under a ladder (thereby creating a superstition in their minds), partly because it would take too long to explain all about the real dangers of paint-pots and other things, and partly because for the children themselves it seems simpler to have a fixed and inviolable law than to argue over every case that occurs. The priests and elders among early folk no doubt took the line of FORBIDDAL of activities, as safer and simpler, even if carried sometimes too far, than the opposite, of easy permission and encouragement. Taboos multiplied--many of them quite senseless--but perhaps in this perilous maze of the world, of which I have spoken, it really WAS simpler to cut out a large part of the labyrinth, as forbidden ground, thus rendering it easier for the people to find their way in those portions of the labyrinth which remained. If you read in Deuteronomy (ch. xiv) the list of birds and beasts and fishes permitted for food among the Israelites, or tabooed, you will find the list on the whole reasonable, but you will be struck by some curious exceptions (according to our ideas), which are probably to be explained by the necessity of making the rules simple enough to be comprehended by everybody--even if they included the forbiddal of some quite eatable animals.
