“If I were to live to the world's end, and do all the good that man can do, I must still cry, " Mercy!" Why then should I be unwilling or afraid to die this moment, with a sense of God's pardoning love, when I can have no other claim to salvation if I were to live forever?”

“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.”

“Please, know that for as long as I live I will be haunted with the sorrow for what I did and when I die I will have counted it more mercy than I deserved to have lived the life I did. Until that day, I want you to also know, I will spend my life trying to do things that will touch the world in a good way, to give back for all I took from you. That’s the only thing I can offer with my hands and my heart. It’s simply all I have.”

“Do not believe that others will die, not you…. I have wrestled with Thanatos knee to knee and I know how death is vanquished. Man's immortality is not to live forever; for that wish is born of fear. Each moment free from fear makes a man immortal.”

“When I said I would die a bachelor, I did not think I should live till I were married.”

“Live a good long life. Grow old and die after I do. And if you can, die laughing.”

“When a human kills an animal for food, he is neglecting his own hunger for justice. Man prays for mercy, but is unwilling to extend it to others. Why should man then expect mercy from God? It's unfair to expect something that you are not willing to give. It is inconsistent. I can never accept inconsistency or injustice. Even if it comes from God. If there would come a voice from God saying, "I'm against vegetarianism!" I would say, "Well, I am for it!" This is how strongly I feel in this regard.”

“I have lived my life according to this principle: If I'm afraid of it, then I must do it.”

“What is my life for and what am I going to do with it? I don't know and I'm afraid. I can never read all the books I want; I can never be all the people I want and live all the lives I want.”

“I love my fellow-creatures, I do all the good I can,
Yet everybody says I'm such a disagreeable man
And I can't think why!”
