"The continual endeavor of man should be to lessen the sum of suffering and cruelty: that is the first duty of humanity."

“You are a vain fellow. You want to be a hero. That is why you do such silly things. A hero! ... I don't quite know what that is: but, you see, I imagine that a hero is a man who does what he can. The others do not do it.”

“Skepticism, riddling the faith of yesterday, prepared the way for the faith of tomorrow.”

“It is the artist's business to create sunshine when the sun fails.”

“He could not think of the animals without shuddering in anguish. He looked into the eyes of the beasts and saw there a soul like his own, a soul which could not speak; but the eyes cried for it: "What have I done to you? Why do you hurt me?" He could not bear to see the most ordinary sights that he had seen hundreds of times—a calf crying in a wicker pen, with its big, protruding eyes, with their bluish whites and pink lids, and white lashes, its curly white tufts on its forehead, its purple snout, its knock-kneed legs:—a lamb being carried by a peasant with its four legs tied together, hanging head down, trying to hold its head up, moaning like a child, bleating and lolling its gray tongue:—fowls huddled together in a basket:—the distant squeals of a pig being bled to death:—a fish being cleaned on the kitchen-table.... The nameless tortures which men inflict on such innocent creatures made his heart ache. Grant animals a ray of reason, imagine what a frightful nightmare the world is to them: a dream of cold-blooded men, blind and deaf, cutting their throats, slitting them open, gutting them, cutting them into pieces, cooking them alive, sometimes laughing at them and their contortions as they writhe in agony. Is there anything more atrocious among the cannibals of Africa? To a man whose mind is free there is something even more intolerable in the sufferings of animals than in the sufferings of men. For with the latter it is at least admitted that suffering is evil and that the man who causes it is a criminal. But thousands of animals are uselessly butchered every day without a shadow of remorse. If any man were to refer to it, he would be thought ridiculous.—And that is the unpardonable crime. That alone is the justification of all that men may suffer.”

“In the great philosophy of Brahma, such violent turns of the scale are quite unknown. It embraces vast stretches of time, cycles of human ages, whose successive lives gravitate in concentric circles, and travel ever slowly towards the center....”

“The slaughter accomplished by man is so small a thing of itself in the carnage of the universe! The animals devour each other. The peaceful plants, the silent trees, are ferocious beasts one to another. The serenity of the forests is only a commonplace of easy rhetoric for the literary men who only know Nature through their books! ... In the forest hard by, a few yards away from the house, there were frightful struggles always toward. The murderous beeches flung themselves upon the pines with their lovely pinkish stems, hemmed in their slenderness with antique columns, and stifled them. They rushed down upon the oaks and smashed them, and made themselves crutches of them. The beeches were like Briareus with his hundred arms, ten trees in one tree! They dealt death all about them. And when, failing foes, they came together, they became entangled, piercing, cleaving, twining round each other like antediluvian monsters. Lower down, in the forest, the acacias had left the outskirts and plunged into the thick of it and, attacked the pinewoods, strangling and tearing up the roots of their foes, poisoning them with their secretions. It was a struggle to the death in which the victors at once took possession of the room and the spoils of the vanquished. Then the smaller monsters would finish the work of the great. Fungi, growing between the roots, would suck at the sick tree, and gradually empty it of its vitality. Black ants would grind exceeding small the rotting wood. Millions of invisible insects were gnawing, boring, reducing to dust what had once been life.... And the silence of the struggle! ... Oh! the peace of Nature, the tragic mask that covers the sorrowful and cruel face of Life!”
