Judaism has three major types of food prohibitions. One is unhealthy food, such as suet. Another is swarming and creeping creatures. While some peoples with limited access to other forms of necessary protein eat them, the revulsion they cause universally suggests that the Judaic prohibition is not arbitrary. The prohibition of eating all but four animals is unrelated to filth; valuable camels and horses are also prohibited. People are not filthy, but eating them is prohibited and filthy. The pig was originally a respectable animal, and for that very reason eating it was disgusting. Eventually, that disgust passed to the pig itself. The Torah, unlike totemic religions, does not prohibit “sacred” animals but establishes the criteria of hooves and rumination, likely related to the animals’ intellect. The permitted animals are folklore examples of foolishness: cows, sheep, goats, and gazelles. Similarly, the truly scaleless—prohibited—fish are sea mammals, smart compared to other fish. The Hebrews knew nothing of dolphins nor that pigs are anatomically close to humans. Judaism prohibits swarming creatures, and see how incredibly smart ants and bees are. Life is sacred, and people may not kill even animals, but humans must eat; the concession is made, therefore, to let people kill a few intellectually less advanced animals, and even that was limited to domestic animals who people raised in the first place and rigidly regulated to minimize suffering. Judaism does not prohibit cheeseburgers. Maimonides noted that the prohibition of boiling a kid in its mother’s milk is in the section of rules that forbid pagan customs, not in the food laws section. The pagans had such rite, and the Bible prohibits it. That is not a food prohibition and need not be expanded to cover all meat-milk cooking.
