"Animals are rational; in most of them logos is imperfect, but it is certainly not wholly lacking. So if, as our opponents say, justice applies to rational beings, why should not justice, for us, also apply to animals?"

"I think that when friendship and perception of kinship ruled everything, no one killed any creature, because people thought the other animals were related to them."

"The industrialization — and brutalization — of animals in America is a relatively new, evitable, and local phenomenon: No other country raises and slaughters its food animals quite as intensively or as brutally as we do. No other people in history has lived at quite so great a remove from the animals they eat. Were the walls of our meat industry to become transparent, literally or even figuratively, we would not long continue to raise, kill, and eat animals the way we do."

"We see that kindness or humanity has a larger field than bare justice to exercise itself in; law and justice we cannot, in the nature of things, employ on others than men; but we may extend our goodness and charity even to irrational creatures; and such acts flow from a gentle nature, as water from an abundant spring. It is doubtless the part of a kind-natured man to keep even worn-out horses and dogs, and not only take care of them when they are foals and whelps, but also when they are grown old."

"Throughout the history of our ascent to dominance as the master species, our victimization of animals has served as the model and foundation for our victimization of each other. The study of human history reveals the pattern: first, humans exploit and slaughter animals; then, they treat other people like animals and do the same to them."

"If you once admit that all that is most wonderful in the actions of beasts, may be done by means of a material soul; will you not soon grant what follows, and say, that all that passes in man may be also done by a material soul? ... If you once grant that beasts, without any spiritual soul, are capable of thinking, of acting for an end, of foreseeing things to come, of remembering what is past, of acquiring experience by the particular reflection they make upon it; why will you not grant that men are capable of exercising their functions without any spiritual soul?"

"All animals are equal — but some animals are more equal than others."

"Four legs good, two legs bad."

"The creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which."

"Now what is it that moves our very hearts and sickens us so much at cruelty shown to poor brutes? ... They have done us no harm and they have no power of resistance; it is the cowardice and tyranny of which they are the victims which make their sufferings so especially touching. Cruelty to animals is as if man did not love God. ... There is something so very dreadful, so Satanic, in tormenting those who have never harmed us, who cannot defend themselves, who are utterly in our power."

"The animals are our brothers; another nation living on earth, growing up beside us. They are not lesser beings; they are selves in different forms. Some of them have flippers, some wings for motivation; some have two propelling legs, some have four; we have only two. Some have thumbs, some have claws. We have manufactured claws and worse. We have no rights over these creatures; yet we exploit and imprison them. They should run wild and be on their own but we have corrupted them, enslaved them and modified their behavior and opportunities. Some of them like it, some don't. We have made friends of some and slaves of others."

"In former days all animals could speak and so could the flowers, the trees and the stones and all lifeless things who were all created by the same God who had created man. Therefore man should be kind to all animals, and treat all lifeless things as if they could still hear and understand. On the day of the Last Judgement the animals would be called in first by God to give evidence against the dead man. Only after the animals had had their say would his fellow creatures be called in as witnesses."

"A prostitute was forgiven by Allah, because, passing by a panting dog near a well and seeing that the dog was about to die of thirst, she took off her shoe, and tying it with her head-cover she drew out some water for it. So, Allah forgave her because of that."

"While a man was walking along a road, he became very thirsty and found a well. He lowered himself into the well, drank, and came out. Then [he saw] a dog protruding its tongue out with thirst. The man said: "This dog has become exhausted from thirst in the same way as I." He lowered himself into the well again and filled his shoe with water. He gave the dog some water to drink. He thanked God, and [his sins were] forgiven. The Prophet was then asked: "Is there a reward for us in our animals?" He said: "There is a reward in every living thing."

"Cruelty to animals is an enormous injustice; so is expecting those on the lowest rung of the economic ladder to do the dangerous, soul-numbing work of slaughtering sentient beings on our behalf."

"For my own part, I cannot without grief see so much as an innocent beast pursued and killed that has no defence, and from which we have received no offence at all."

"Granted that any practice causes more pain to animals than it gives pleasure to man; is that practice moral or immoral? And if, exactly in proportion as human beings raise their heads out of the slough of selfishness, they do not with one voice answer 'immoral,' let the morality of the principle of utility be for ever condemned."

"It is an act of cruelty, of barbarism, to kill, to strike unconscious, and to cut the throat of animals, who do no harm to anyone, the way we do; because they are sensitive to injury and pain just as we are, regardless of what is said vainly, falsely, and ridiculously by our new Cartesians, who regard them as purely machines without soul and without feelings ... This is a ridiculous opinion, a pernicious principle, and a detestable doctrine, because it clearly tends to stifle in the hearts of men all feelings of kindness, of gentleness, and of humanity that they might have toward these poor animals. ... Blessed are the nations that treat them kindly and favorably, who are compassionate toward their miseries and their pains; but cursed are the nations that treat them cruelly, who tyrannize over them, who enjoy shedding their blood, and who are avid to eat their flesh."
