"There are many people who have undergone great suffering who seem to possess knowledge of the deepest recesses of human emotion unavailable to the rest of us. They may want to impart it, but we often cannot hear. Strangely enough, farm animals strike me in the same way."
"We have an easy time thinking of animals as animals in part because they smell like animals. But what are you supposed to think when you find a group of humans who smell no better than cows, even worse? It reminds you that humans are animals, with the ability to stink like pigs, and kill like the wolves."
"If we cut up beasts simply because they cannot prevent us and because we are backing our own side in the struggle for existence, it is only logical to cut up imbeciles, criminals, enemies, or capitalists for the same reasons."
"Never better than after the last four centuries of his history could a Western man understand that, while assuming the right to impose a radical separation of humanity and animality, while granting to one all that he denied the other, he initiated a vicious circle. The one boundary, constantly pushed back, would be used to separate men from other men and to claim—to the profit of ever smaller minorities—the privilege of a humanism, corrupted at birth by taking self-interest as its principle and its notion."
"It is abundantly evident, both from history and from present experience, that the instinctive shock, or natural feeling of disgust, caused by the sight of the sufferings of men is not generically different from that which is caused by the sight of the sufferings of animals."
"At one time the benevolent affections embrace merely the family, soon the circle expanding includes first a class, then a nation, then a coalition of nations, then all humanity, and finally, its influence is felt in the dealings of man with the animal world. In each of these stages a standard is formed, different from that of the preceding stage, but in each case the same tendency is recognised as virtue."
"Cet animal est tres méchant; Quand on l'attaque il se défend."
"Man only is endowed with wisdom so as to understand religion, and this is the principal if not the only difference betwixt him and dumb animals; for other things that seem peculiar to him, though they are not the same in them, yet they appear to be alike ... What is there more peculiar to man than reason, and foresight? Yet there are animals which make several different ways of retiring from their dens; that when in danger they may escape; which without understanding and forethought they could not do. Others make provision for the future."
"True human goodness, in all its purity and freedom, can come to the fore only when its recipient has no power. Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude toward those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it."
"Thus our duties to animals are indirectly duties to humanity."
"The more we devote ourselves to observing animals and their behaviour, the more we love them, on seeing how gready they care for their young; in such a context, we cannot even contemplate cruelty to a wolf. Leibnitz put the grub he had been observing back on the tree with its leaf, lest he should be guilty of doing any harm to it. It upsets a man to destroy such a creature for no reason, and this tenderness is subsequendy transferred to man."
"A person who already displays ... cruelty to animals is also no less hardened towards men. We can already know the human heart, even in regard to animals."
"But ask now the beasts, and they shall teach thee; and the fowls of the air, and they shall tell thee: Or speak to the earth, and it shall teach thee: and the fishes of the sea shall declare unto thee. Who knoweth not in all these that the hand of the LORD hath wrought this? In whose hand is the soul of every living thing, and the breath of all mankind."
"How will man, that sanguinary tyrant, be able to excuse himself from the charge of those innumerable cruelties inflicted on his unoffending subjects committed to his care, formed for his benefit, and placed under his authority by their common Father?"
"To my way of thinking there's something wrong, or missing, with any person who hasn't got a soft spot in their heart for an animal of some kind. With most folks the dog stands highest as man's friend, then comes the horse, with others the cat is liked best as a pet, or a monkey is fussed over; but whatever kind of animal it is a person likes, it's all hunkydory so long as there's a place in the heart for one or a few of them."
"Siquidem et per naturam pleraque mutationem recipiunt, et corrupta in diversas species transformantur; sicut de vitulorum carnibus putridis apes, sicut de equis scarabei, de mulis locustae, de cancris scorpiones."
"We have enslaved the rest of the animal creation, and have treated our distant cousins in fur and feathers so badly that beyond doubt, if they were able to formulate a religion, they would depict the Devil in human form."
"We know, that, in the individual man, consciousness grows from a dim glimmer to its full light, whether we consider the infant advancing in years, or the adult emerging from slumber and swoon. We know, further, that the lower animals possess, though less developed, that part of the brain which we have every reason to believe to be the organ of consciousness in man; and as, in other cases, function and organ are proportional, so we have a right to conclude it is with the brain; and that the brutes, though they may not possess our intensity of consciousness, and though, from the absence of language, they can have no trains of thoughts, but only trains of feelings, yet have a consciousness which, more or less distinctly, foreshadows our own. I confess that, in view of the struggle for existence which goes on in the animal world, and of the frightful quantity of pain with which it must be accompanied, I should be glad if the probabilities were in favour of Descartes' hypothesis; but, on the other hand, considering the terrible practical consequences to domestic animals which might ensue from any error on our part, it is as well to err on the right side, if we err at all, and deal with them as weaker brethren, who are bound, like the rest of us, to pay their toll for living, and suffer what is needful for the general good."
"'Tis evident, that sympathy, or the communication of passions, takes place among animals, no less than among men. Fear, anger, courage and other affections are frequently communicated from one animal to another [...] And 'tis remarkable, that tho' almost all animals use in play the same member, and nearly the same action as in fighting; a lion, a tyger, a cat their paws; an ox his homs; a dog his teeth; a horse his heels: Yet they most carefully avoid harming their companion, even tho' they have nothing to fear from his resentment; which is an evident proof of the sense brutes have of each other's pain and pleasure."
"The very port and gait of a swan, or turkey, or peacock show the high idea he has entertain'd of himself; and his contempt of all others. This is the more remarkable, that in the two last species of animals, the pride always attends the beauty, and is discover'd in the male only. The vanity and emulation of nightingales in singing have been commonly remark'd [...] All these are evident proofs, that pride and humility are not merely human passions, but extend themselves over the whole animal creation."
"'Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step farther, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling."
"Next to the ridicule of denying an evident truth, is that of taking much pains to defend it; and no truth appears to me more evident, than that beasts are endow'd with thought and reason as well as men. The arguments are in this case so obvious, that they never escape the most stupid and ignorant."
"There are probably no creatures that require more the protective Divine word against the presumption of man than the animals, which, like man, have sensations and instincts, but whose body and powers are nevertheless subservient to man. In relation to them man so easily forgets that injured animal muscle twitches just like human muscle, that the maltreated nerves of an animal sicken like human nerves, that the animal being is just as sensitive to cuts, blows and beating as man. Thus man becomes the torturer of the animal soul, which has been subjected to him only for the fulfilment of humane and wise purposes; sometimes out of self-interest, at other times in order to satisfy a whim, sometimes out of thoughtlessness—yes, even for the satisfaction of crude satanic desire."
"We seem to be in the place of God to them, to be his vice-regents, and empowered to receive homage from them in his name. And we are obliged, by the same tenure, to be their guardians and benefactors."
"In fact if one person is unkind to an animal it is considered to be cruelty, but where a lot of people are unkind to a lot of animals, especially in the name of commerce, the cruelty is condoned and, once large sums of money are at stake, will be defended to the last by otherwise intelligent people."
"The fate of farm animals is not an ethical side issue. It concerns the majority of Earth's large creatures: tens of billions of sentient beings, each with a complex world of sensations and emotions, but who live and die as cogs in an industrial production line."
"Animals are the main victims of history, and the treatment of domesticated animals in industrial farms is perhaps the worst crime in history."
"To understand animal thinking you've got to get away from a language. See my mind works like Google for images. You put in a key word; it brings up pictures. See language for me narrates the pictures in my mind. When I work on designing livestock equipment I can test run that equipment in my head like 3-D virtual reality. In fact, when I was in college I used to think that everybody was able to do that. And language just sort of, you know, gives an opinion. Like, oh, that's a good idea or oh, I just figured out how to design that. ... I designed a system holding a cattle in the meat plant, where they straddle a conveyor. And if you get things set up right they just walk in really quietly. And you've got to get the lighting right. They're afraid of the dark. If the lights were going, blasting in their eyes like the sun or there's a reflection on a shinny piece of metal moving, they're going to be afraid of that. And you get rid of those things their afraid of then their going to walk right in. You know, the things that scare a prey/species animal like cattle are a whole lot of little visual details that people just don't tend to notice. And one of the big problems they used to have is the people just wanted to get out there and yell and scream and push and shove and you know more and more prods. Rather than remove the things that the cattle were afraid of."
"Animals when in company walk in a proper and sensible manner, in single file, instead of sprawling all across the road and being of no use or support to each other in case of sudden trouble or danger."
"I wanted to talk to the animals like Dr. Dolittle."
"The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man—whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them."
"Thousands of people who say they "love" animals sit down once or twice a day to enjoy the flesh of creatures who have been utterly deprived of everything that could make their lives worth living and who endured the awful suffering and the terror of the abattoirs — and the journey to get there — before finally leaving their miserable world, only too often after a painful death."
"Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings. They don't want to admit that they might have minds and personalities because that would make it quite difficult for them to do what they do; so we find that within the lab communities there is a very strong resistance among the researchers to admitting that animals have minds, personalities and feelings."
"What humiliation, what disgrace for us all, that it should be necessary for one man to exhort other men not to be inhuman and irrational towards their fellow-creatures! Do they recognise, then, no mind, no soul in them — have they not feeling, pleasure in existence, do they not suffer pain? Do their voices of joy and sorrow indeed fail to speak to the human heart and conscience — so that they can murder the jubilant lark, in the first joy of his spring-time, who ought to warm their hearts with sympathy, from delight in bloodshed or for their ‘sport,’ or with a horrible insensibility and recklessness only to practise their aim in shooting! Is there no soul manifest in the eyes of the living or dying animal — no expression of suffering in the eye of a deer or stag hunted to death — nothing which accuses them of murder before the avenging Eternal Justice? .... Are the souls of all other animals but man mortal, or are they essential in their organisation? Does the world-idea (Welt-Idee) pertain to them also — the soul of nature — a particle of the Divine Spirit? I know not; but I feel, and every reasonable man feels like me, it is in miserable, intolerable contradiction with our human nature, with our conscience, with our reason, with all our talk of humanity, destiny, nobility; it is in frightful (himmelschreinder) contradiction with our poetry and philosophy, with our nature and with our (pretended) love of nature, with our religion, with our teachings about benevolent design — that we bring into existence merely to kill, to maintain our own life by the destruction of other life. .... It is a frightful wrong that other species are tortured, worried, flayed, and devoured by us, in spite of the fact that we are not obliged to this by necessity; while in sinning against the defenceless and helpless, just claimants as they are upon our reasonable conscience and upon our compassion, we succeed only in brutalising ourselves. This, besides, is quite certain, that man has no real pity and compassion for his own species, so long as he is pitiless towards other races of beings."
"Animals are not here for us to do as we please with. We are not their superiors, we are their equals. We are their family. Be kind to them."
"Animals are always loyal and love you, whereas children you never know where you are."
"What, then, is the animal? First of all, a system of plant-souls. The unity of those plant-souls, which unity nature itself produces, is the soul of the animal. Its world is therefore partly that of the plants — its nourishment, for instance, it receives partly through synthesis from vegetable, and through analysis from animal nature — and partly that of the animals, whereof we shall speak directly. ... Each product of nature is an organically in-itself completed totality in space, like the plant. Hence, the unknown x which we are looking for must also be such a whole or totality, and in so far it must also have a principle of organization, a sphere and central point of this organization; in short, the same which we have called the soul of the plant, which thus remains common to both. ... The animal is a system of plant-souls, and the plant is a separated, isolated part of an animal. Both reciprocally affect each other."
"“Our choices as consumers ... cause miners to go in there and come in contact with wild animals that carry viruses. We implicate ourselves in this chain of consumer supply and demand,” says David Quammen, author of the book Spillover: Animal Infections and the Next Human Pandemic. “That is one of the broader causes of contact with wild animals that leads to spillover of new viruses with the potential of becoming epidemic and pandemic,” says Quammen. Take gold, for example, which is used in a lot of electronics because it conducts electricity pretty well. Marburg, a viral hemorrhagic fever similar to Ebola, killed 128 people in Congo between 1998 and 2000. Scientists surmised that gold miners probably picked up the virus from animals, like bats, in mines, and the virus spread from there."
"Animals are such agreeable friends - they ask no questions, they pass no criticisms."
"[I]n lower organisms, there is at once great reproductive power and a complete absence of sexual attraction, from the very fact that the sexes are not differentiated. With more advanced organisms, the sexual attraction increases as the reproductive force diminishes, until, at the summit, with man, the strongest sexual love becomes visible, even in the case of a total absence of reproduction. And thus, if at the two extremes of animal life we find, on the one hand, reproduction without sexual love, and, on the other, sexual love without reproduction."
"For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no preeminence above a beast: for all is vanity. All go unto one place; all are of the dust, and all turn to dust again."
"Lest I slight any creature, I must also mention the domestic animals, the beasts and birds from whom I have learned. Job said long ago (35:11): «Who teacheth us more than the beasts of the earth, And maketh us wiser than the fowls of heaven?» Some of what I have learned from them I have written in my books, but I fear that I have not learned as much as I should have, for when I hear a dog bark, or a bird twitter, or a cock crow, I do not know whether they are thanking me for all I have told of them, or calling me to account."
"I’ve had the privilege of living underwater on 10 different occasions. It has enabled me to get to know individual moray eels, individual groupers, even individual lobsters. They all have faces, they have attitudes. They have sensory systems much like our own. And yet we somehow harden ourselves to think they don’t feel pain. We pride ourselves on being “humane” but it doesn’t translate to the way we treat animals in the sea."
"Love the animals: God has given them the rudiments of thought and untroubled joy. So do not trouble it, do not harass them, do not deprive them of their joy, do not go against God's intent. Man, do not exhale yourself above the animals: they are without sin, while you in your majesty defile the earth by your appearance on it, and you leave the traces of your defilement behind you — alas, this is true of almost every one of us!"
"There is no Animal in the general singular, separated from man by a single, indivisible limit. We have to envisage the existence of “living creatures,” whose plurality cannot be assembled within the single figure of an animality that is simply opposed to humanity. ... The confusion of all nonhuman living creatures within the general and common category of the animal is not simply a sin against rigorous thinking, vigilance, lucidity, or empirical authority, it is also a crime. Not a crime against animality, precisely, but a crime of the first order against the animals, against animals."
"Confined within this catch-all concept, within this vast encampment of the animal, in this general singular, within the strict enclosure of this definite article (“the Animal” and not “animals”), as in a virgin forest, a zoo, a hunting or fishing ground, a paddock or an abattoir, a space of domestication, are all the living things that man does not recognize as his fellows, his neighbors, or his brothers."
"No one can deny the suffering, fear, or panic, the terror or fright that can seize certain animals and that we humans can witness. ... No doubt either, then, of there being within us the possibility of giving vent to a surge of compassion, even if it is then misunderstood, repressed, or denied, held at bay. ... The two centuries I have been referring to somewhat casually in order to situate the present in terms of this tradition have been those of an unequal struggle, a war (whose inequality could one day be reversed) being waged between, on the one hand, those who violate not only animal life but even and also this sentiment of compassion, and, on the other hand, those who appeal for an irrefutable testimony to this pity. War is waged over the matter of pity. This war is probably ageless but, and here is my hypothesis, it is passing through a critical phase. We are passing through that phase, and it passes through us. To think the war we find ourselves waging is not only a duty, a responsibility, an obligation, it is also a necessity, a constraint that, like it or not, directly or indirectly, no one can escape. Henceforth more than ever. And I say “to think” this war, because I believe it concerns what we call “thinking.” The animal looks at us, and we are naked before it. Thinking perhaps begins there."
"Men will seem to see new destructions in the sky. The flames that fall from it will seem to rise in it and to fly from it with terror. They will hear every kind of animals speak in human language. They will instantaneously run in person in various parts of the world, without motion. They will see the greatest splendour in the midst of darkness. O! marvel of the human race! What madness has led you thus! You will speak with animals of every species and they with you in human speech. You will see yourself fall from great heights without any harm and torrents will accompany you, and will mingle with their rapid course."
"Sympathy beyond the confines of man, that is humanity to the lower animals, seems to be one of the latest moral acquisitions. It is apparently unfelt by savages, except towards their pets. ... This virtue, one of the noblest with which man is endowed, seems to arise incidentally from our sympathies becoming more tender and more widely diffused, until they are extended to all sentient beings. As soon as this virtue is honoured and practised by some few men, it spreads through instruction and example to the young, and eventually through public opinion."
"As dogs, cats, horses, and probably all the higher animals, even birds, as is stated on good authority, have vivid dreams, and this is shewn by their movements and voice, we must admit that they possess some power of imagination. ... Few persons any longer dispute that animals possess some power of reasoning. Animals may constantly be seen to pause, deliberate, and resolve. It is a significant fact, that the more the habits of any particular animal are studied by a naturalist, the more he attributes to reason and the less to unlearnt instincts."
