"No one can eat the flesh of a slaughtered animal without having used the hand of a man as slaughterer. Suppose that we had to kill for ourselves the creatures whose bodies we would fain have upon our table, is there one woman in a hundred who would go to the slaughterhouse to slay the bullock, the calf, the sheep or the pig? ... But if we could not do it, nor see it done; if we are so refined that we cannot allow close contact between ourselves and the butchers who furnish this food; if we feel that they are so coarsened by their trade that their very bodies are made repulsive by the constant contact of the blood with which they must be continually besmirched; ... dare we call ourselves refined if we purchase our refinement by the brutalization of others, and demand that some should be brutal in order that we may eat the results of their brutality? We are not free from the brutalizing results of that trade simply because we take no direct part in it."
