Myśl Żydowska do Wyjścia 34:20

Having referred to man's intellectual superiority over the animal kingdom on several occasions, the Torah turns to our physical superiority and dominion over the animals by permitting animals to serve as our food. Far from depriving even the most primitive creature of a meaningful exterior, the Torah is most emphatic that the appearance of each creature be maintained by insisting that there be no crossbreeding between species. The eating of animals had been prohibited to earlier generations in order to prevent man who had already been deeply corrupted from absorbing more animalistic characteristics, which in turn would have hastened his total corruption. When the Talmud forbids meat intake to the am ha-aretz, the ignorant person, the term means primitive man, the kind of person whom it is permitted to kill even on the Day of Atonement, even when the latter occurs on the holy Sabbath (Pessachim 49). In other words, it refers to a member of the human race who is so depraved, has lost all claim to being numbered among the human species. When someone like that eats meat, he undoubtedly destroys further whatever vestige of humanity he had still retained.
