“I am a vegetarian, therefore, because cannibalism is unnecessarily. I can live just as well and be just as happy without drinking the blood of my fellows and why should I slay them? Why should I not live and let live—especially when I can do it just as well as not? It is not necessary that ten thousand creatures should give up their lives in order that I may keep mine, and if I make any pretensions to morality why should I require them to do it? If you say such a thing is necessary in your case, I say to you it is not—and further, that if it were, it would be your duty as an ethical being to call on your undertaker. There is no sense in carnivora talking about ethics and justice and mercy, for their very existence is a travesty on such things. It makes me indignant and sad when I hear men deplore sin and prate about justice and love and mercy when the very energy they expend in preaching justice and mercy is obtained from the skeletons and sensibilities of their fellows. It is a spectacle that ought to make the imps of netherdom tremble for their laurels—man, the remorseless glutton, going about with a tongue and a knife, with his tongue preaching peace, mercy, and love, and with his knife making the very earth sodden with blood.”
