“Man is the only animal that deals in that atrocity of atrocities War. He is the only one that gathers his brethren about him and goes forth in cold blood and calm pulse to exterminate his kind. He is the only animal that for sordid wages will march out... and help to slaughter strangers of his own species who have done him no harm and with whom he has no quarrel.... And in the intervals between campaigns he washes the blood off his hands and works for the universal brotherhood of man with his mouth.”

“Man is a Religious Animal. He is the only Religious Animal. He is the only animal that has the True Religion--several of them. He is the only animal that loves his neighbor as himself and cuts his throat if his theology isn't straight. He has made a graveyard of the globe in trying his honest best to smooth his brother's path to happiness and heaven....The higher animals have no religion. And we are told that they are going to be left out in the Hereafter. I wonder why? It seems questionable taste.”

“Once my imagination persuaded me that the dying man gave me a reproachful look out of his shadowy eyes, and it seemed to me that I could rather he had stabbed me than done that. He muttered and mumbled like a dreamer in his sleep, about his wife and his child; and I thought about a new despair, "This thing that I have done does not end with him; it falls upon them too and they never did me any harm... The man was not in uniform, and was not armed. He was a stranger in the country; that was all we ever found out about him. The thought of him got to preying upon me every night; I could not get rid of it. I could not drive it away, the taking of that unoffending life seemed such a wanton thing. And it seemed an epitome of war; that all war must be just that -- the killing of strangers against whom you feel no personal animosity; strangers whom, in other circumstances, you would help if you found them in trouble, and who would help you if you needed it. My campaign was spoiled. It seemed to me I was not rightly equipped for this awful business; that war was intended for men, and I for a child's nurse.”

“He said that man’s heart was the only bad heart in the animal kingdom; that man was the only animal capable of feeling malice, envy, vindictiveness, revengefulness, hatred, selfishness, the only animal that loves drunkenness, almost the only animal that could endure personal uncleanliness and a filthy habitation, the sole animal in whom was fully developed the base instinct called patriotism, the sole animal that robs, persecutes, oppresses and kills members of his own tribe, the sole animal that steals and enslaves the members of any tribe.”

“Man is the only animal that loves his neighbor as himself and cuts his throat if his theology isn't straight”

“Man never creates, he only recombines the lines and colors of his own existance.”

“Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it.”
