in Genesis, or Balaam's ass. In the most remote periods it is probable that every clan had at least one totem animal which might no more be killed or eaten than the human individuals of the clan. The totem was protected by taboo. The totem was sacred and in this capacity it was looked upon as a source of strength and holiness, and to live beside it and under its protection was considered as a righteous custom. In certain communities the idea that it was necessary to abstain from eating certain totems survived the progress of material civilization. The cow is taboo to the Hindus, the pig is taboo to the Mohammedans and to the Jews. The pious Jew abstains from pork because his remote ancestors, five or six thousand years before our era, had the wild boar as their totem. This is the origin of this alimentary taboo; among the ancient Hebrews it arose, and only comparatively recently has it been suggested that the flesh of these taboo animals was unwholesome. In the eighteenth century, philosophers, propagated the erroneous notion that if certain religious legislators had forbidden various aliments, it was for hygienic motives. Even Renan believed that dread of trichinosis and leprosy had caused the Hebrews to forbid the use of pork. To show the irrational nature of this explanation, it will be enough to point out that in the whole of the Bible there is not a single instance of an epidemic or a malady attributed to the eating of unclean meats; the idea of hygiene awoke very late in the Greek world. To the Biblical writers, as to contemporary savages, illness is supernatural; it is an effect of the wrath of spirits.
Primitive man ascribed all diseases either to the wrath of God, or the malice of an evil being. The curing of disease by the casting out of devils and by prayers were the means of relief from sickness recognized
