Henry Shakespear Stephens Salt,
A Plea for Vegetarianism and Other Essays
(1886)
“ The fact that the structure of the human body is wholly unlike that of the carnivora, and that the apes, who are nearest akin to us in the animal world, are frugivorous, is a somewhat strong indication that flesh is not the natural food of mankind. And if it be said that man, unlike other creatures, is omni-vorous, and has therefore to seek not what is "natural," but what is best, then I readily accept the challenge, and reply that there is a strong concurrence of proof, on economic, moral, and physical grounds, that a vegetarian diet is the most suitable and beneficial. ”
