We have some little difficulty in our times, familiar as we are with spiritual conceptions of God and the divine purposes, in comprehending the extreme importance which sacrifices, offerings, gifts to the divine being, assumed in the eyes of peoples who were still enveloped in the darkness of polytheism and idolatry. And perhaps we may find it more difficult yet to realize the primitive object and intention of these sacrifices. There can be no doubt that they were originally suggested by the idea that the divine being, whatever it may have been--whether a natural object, an animal, or a creature analogous to man--liked what we like, was pleased with what pleases us, and had the same tastes and the same proclivities as ours. This is the fundamental idea that urged the polytheistic peoples along the path of religious anthropomorphism.
This principle once established, and the object being to secure the goodwill and the protection of the divine beings, what could be more natural than to offer them the things in which men themselves took pleasure, such as viands, drinks, perfumes, handsome ornaments, slaves and wives? We must not carry back to the origins of sacrifice the meta-physical and moral ideas which did not really appear until much later. And since the necessity of eating, and the pleasure of eating choice food, take a foremost rank in the estimation of infant peoples, it is not surprising that the food-offering was the most frequent and the most important amongst them, so as in some sort to absorb all the rest.
And here we are compelled to bow before a fact which cannot possibly be disputed, namely, that traces of the primitive sacrifice of human victims meet us everywhere. And this shows that cannibalism, which is now restricted to a few of the savage tribes who have remained closest to the animal life, was once universal to our race. For no one would ever have conceived the idea of offering to the gods a kind of food which excited nothing but disgust and horror amongst men.
This being granted, two rival tendencies must be reckoned with. In the first place, moral development, with its influence on religious ideas, worked towards the suppression of the horrible custom of human sacrifice, whilst at the same time extirpating the taste and desire for human flesh. For we must not forget that where cannibalism still reigns, human flesh is regarded as the most delicious of foods; and the Greek mythology has preserved legends and myths that are connected with the very epoch at which human sacrifices first became an object of horror to gods and men. But, in the second place, in virtue of the strange persistency of rites and usages connected with religion, human sacrifices prevailed in many places when cannibalism had completely disappeared from the habits and tastes of the population. Thus the Semites of Western Asia and the Çivaïte Hindus, the Celts, and some of the populations of Greece and Italy, long after they had renounced cannibalism, still continued to sacrifice human beings to their deities.
