Animals

Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). All animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance.

Quotes

Organized alphabetically by author.

 * 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.
 * Shmuel Yosef Agnon, Speech at the Nobel Banquet at the City Hall in Stockholm (10 December 1966), in Nobelprize.org.

 * But if man's affection be one of passion, then it is moved also in regard to other animals: for since the passion of pity is caused by the afflictions of others; and since it happens that even irrational animals are sensible to pain, it is possible for the affection of pity to arise in a man with regard to the sufferings of animals. Now it is evident that if a man practice a pitiful affection for animals, he is all the more disposed to take pity on his fellow-men: wherefore it is written (Prov. 12:10): "The just regardeth the lives of his beasts: but the bowels of the wicked are cruel." Consequently the Lord, in order to inculcate pity to the Jewish people, who were prone to cruelty, wished them to practice pity even with regard to dumb animals, and forbade them to do certain things savoring of cruelty to animals. Hence He prohibited them to "boil a kid in the milk of its dam"; and to "muzzle the ox that treadeth out the corn"; and to slay "the dam with her young."
 * Thomas Aquinas, Summa Theologica (1265–1274), I-II, q. 102, art. 6 ad. 8.

 * Will you, laying aside all partiality, consider in the silence of your thoughts that we [humans] are creatures either quite like the rest [of animals], or separated by no great difference? For what is there to show that we do not resemble them? or what excellence is in us, such that we scorn to be ranked as creatures? Their bodies are built up on bones, and bound closely together by sinews; and our bodies are in like manner built up on bones, and bound closely together by sinews.
 * Arnobius, Seven Books Against the Heathens (Adversus Nationes), trans. Christian Classics Ethereal Library, Book II, § 16.

 * Oh, God, enlarge within us the sense of fellowship with all living things, our brothers the animals to whom Thou gavest the earth in common with us. We remember with shame that in the past we have exercised the high dominion of man with ruthless cruelty so that the voice of the earth, which should have gone up to thee in song, has been a groan of travail.
 * Basil of Caesarea, in circa A.D. 375. Included in A Select Library of the Nicene and Post-Nicene Fathers of the Christian Church (NPNF), edited by P. Schaff and Henry Wace (Edinburg: T. Clark, 1897), 2nd Series, Vol. 8. Quoted in Matthew Scully, [//books.google.it/books?id=SYY7AAAAQBAJ&pg=PT28 Dominion] (2002).

 * Whatever it may be, animals have always had, until our era, a divine or sacrificial nobility that all mythologies recount. Even murder by hunting is still a symbolic relation, as opposed to an experimental dissection. Even domestication is still a symbolic relation, as opposed to industrial breeding. One only has to look at the status of animals in peasant society. And the status of domestication, which presupposes land, a clan, a system of parentage of which the animals are a part, must not be confused with the status of the domestic pet—the only type of animals that are left to us outside reserves and breeding stations—dogs, cats, birds, hamsters, all packed together in the affection of their master. The trajectory animals have followed, from divine sacrifice to dog cemeteries with atmospheric music, from sacred defiance to ecological sentimentality, speaks loudly enough of the vulgarization of the status of man himself.
 * Jean Baudrillard, Simulacra and Simulation (1981), p. 134

 * '''Those who used to sacrifice animals did not take them for beasts. And even the Middle Ages, which condemned and punished them in due form, was in this way much closer to them than we are, we who are filled with horror at this practice. They held them to be guilty: which was a way of honoring them. We take them for nothing, and it is on this basis that we are "human" with them. We no longer sacrifice them, we no longer punish them, and we are proud of it, but it is simply that we have domesticated them, worse: that we have made of them a racially inferior world, no longer even worthy of our justice, but only of our affection and social charity, no longer worthy of punishment and of death, but only of experimentation and extermination like meat from the butchery.
 * Jean Baudrillard, Simulacra and Simulation (1981), pp. 134–135

 * Animals are born, are sentient and are mortal. In these things they resemble man. In their superficial anatomy — less in their deep anatomy — in their habits, in their time, in their physical capacities, they differ from man. They are both like and unlike.
 * John Berger, About Looking (1980), chapter "Why Look at Animals?", Bloomsbury Publishing, 2015, p. 5.

 * In the first stages of the industrial revolution, animals were used as machines. As also were children. Later, in the so-called post-industrial societies, they are treated as raw material. Animals required for food are processed like manufactured commodities. ... This reduction of the animal ... is part of the same process as that by which men have been reduced to isolated productive and consuming units. Indeed, during this period an approach to animals often prefigured an approach to man. The mechanical view of the animal's work capacity was later applied to that of workers.
 * John Berger, About Looking (1980), chapter "Why Look at Animals?", Bloomsbury Publishing, 2015, pp. 10-11.

 * Even with all our technological accomplishments and urban sophistication, we consider ourselves blessed, healed in some manner, forgiven, and for a moment transported into some other world, when we catch a passing glimpse of an animal in the wild: a deer in some woodland, a fox crossing a field, a butterfly in its dancing flight southward to its wintering region, a hawk soaring in the distant sky, a hummingbird come into our garden, fireflies signaling to each other in the evening. So we might describe the thousandfold moments when we experience our meetings with the animals in their unrestrained and undomesticated status. Such incidents as these remind us that the universe is composed of subjects to be communed with, not of objects to be exploited.
 * Thomas Berry, Evening Thoughts (San Francisco: Sierra Club, 2006), ch. 3, pp. 37-38.

 * Our relation with the animals finds its expression especially in the amazing variety of benefits they provide for us in their guidance, protection, and companionship. Beyond these modes of assistance, they provide a world of wonder and meaning for the mind—beauty for the imagination. Even beyond all these, they provide an emotional intimacy that is unique, that can come to us from no other source. The animals can do for us, both physically and spiritually, what we cannot do for ourselves or for each other. These more precious gifts they provide through their presence and their responsiveness to our inner needs.
 * Thomas Berry, Evening Thoughts (San Francisco: Sierra Club, 2006), ch. 3, p. 39.

 * We find amongst animals, as amongst men, power of feeling pleasure, power of feeling pain; we see them moved by love and by hate; we see them feeling terror and attraction; we recognize in them powers of sensation closely akin to our own, and while we transcend them immensely in intellect, yet, in mere passional characteristics our natures and the animals' are closely allied. We know that when they feel terror, that terror means suffering. We know that when a wound is inflicted, that wound means pain to them. We know that threats bring to them suffering; they have a feeling of shrinking, of fear, of absence of friendly relations, and at once we begin to see that in our relations to the animal kingdom a duty arises which all thoughtful and compassionate minds should recognize - the duty that because we are stronger in mind than the animals, we are or ought to be their guardians and helpers, not their tyrants and oppressors, and we have no right to cause them suffering and terror merely for the gratification of the palate, merely for an added luxury to our own lives.
 * Annie Besant, from a speech given at Manchester UK (18 October 1897).

 * We need another and a wiser and perhaps a more mystical concept of animals. Remote from universal nature, and living by complicated artifice, man in civilization surveys the creature through the glass of his knowledge and sees thereby a feather magnified and the whole image in distortion. We patronize them for their incompleteness, for their tragic fate of having taken form so far below ourselves. And therein we err, and greatly err. For the animal shall not be measured by man. In a world older and more complete than ours they move finished and complete, gifted with extensions of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings; they are other nations, caught with ourselves in the net of life and time, fellow prisoners of the splendour and travail of the earth.
 * Henry Beston, The Outermost House (1928), ch. 2.

 * I believe that animals have rights which, although different from our own, are just as inalienable. I believe animals have the right not to have pain, fear or physical deprivation inflicted upon them by us. Even if they are on the way to the slaughterhouse, animals have the right to food and water and shelter if it is needed. They have the right not to be brutalized in any way as food resources, for entertainment or any other purpose.
 * Roger A. Caras, "We Must Find Alternatives to Animals in Research," in Newsweek (26 December 1988).

 * I shall have to express a very deep conviction: that until we have courage to recognize cruelty for what it is—whether its victim is human or animal—we cannot expect things to be much better in the world. There can be no double standard. We cannot have peace among men whose hearts find delight in killing any living creature. By every act that glorifies or even tolerates such moronic delight in killing, we set back the progress of humanity.
 * Rachel Carson, Letter to Fon Boardman, quoted in Rachel Carson: Legacy and Challenge, ed. Lisa H. Sideris and Kathleen Dean Moore (Albany: State University of New York Press, 2008), p. 102.

 * To any thinking person, it must be obvious that there is something badly wrong in relations between human beings and the animals that human beings rely on for food; and that in the past 100 or 150 years whatever is wrong has become wrong on a huge scale, as traditional animal husbandry has been turned into an industry using industrial methods of production. ... It would be a mistake to idealise traditional animal husbandry as the standard by which the animal-products industry falls short: traditional animal husbandry is brutal enough, just on a smaller scale. A better standard by which to judge both practices would be the simple standard of humanity: is this truly the best that human beings are capable of?
 * J. M. Coetzee, "Animals can't speak for themselves - it's up to us to do it!", in theage.com.au (22 February 2007).

 * He Himself directs the activities of irrational creatures by providing them with certain irresistible inclinations, so that they necessarily employ their faculties for their proper purpose. The effect of this guidance in animals we call instinct. The bird will infallibly use its wings to fly; the bee is certain to employ its marvelously constructed organs to gather pollen and to make honey. But to man, the most exalted of the living things of earth, God grants freedom of choice in the use of his powers. A human being can direct his faculties of soul and of body to the purposes intended by the Creator, or he can distort them to other ends.
 * Francis J. Connell, “Birth Control: The Case for the Catholic”, The Atlantic, (October 1939)

 * The lower animals, like man, manifestly feel pleasure and pain, happiness and misery. Happiness is never better exhibited than by young animals, such as puppies, kittens, lambs, &c., when playing together, like our own children.
 * Charles Darwin, The Descent of Man (1871), volume I, chapter III: "Comparison of the Mental Powers of Man and the Lower Animals — continued", p. 39.

 * Most of the more complex emotions are common to the higher animals and ourselves. Every one has seen how jealous a dog is of his master's affection, if lavished on any other creature; and I have observed the same fact with monkeys. This shews that animals not only love, but have the desire to be loved.
 * Charles Darwin, The Descent of Man (1871), volume I, chapter II: "Comparison of the Mental Powers of Man and the Lower Animals", pp. 41-42

 * 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.
 * Charles Darwin, The Descent of Man (1871), volume I, chapter III: "Comparison of the Mental Powers of Man and the Lower Animals — continued", p. 46.

 * 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.

 * 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.
 * Leonardo da Vinci, The Notebooks of Leonardo Da Vinci (1938), XX Humorous Writings, as translated by Edward MacCurdy.

 * 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.

 * 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.
 * Jacques Derrida, The Animal That Therefore I Am, trans. David Wills, New York: Fordham University Press, 2009 ebook edition, p. 58.

 * 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.
 * Jacques Derrida, The Animal That Therefore I Am, trans. David Wills, New York: Fordham University Press, 2009 ebook edition, p. 76.

 * 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!

 * 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.
 * Sylvia Earle Interview with Time (2021)

 * 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.
 * Ecclesiastes, 3:19-20, King James Version.

 * [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.

 * “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.
 * David Quammen, as quoted in “Tracing the link between your phone and the next pandemic”, by Justine Calma, The Verge, (July 7, 2020)

 * 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.

 * 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.

 * 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.

 * 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.

 * 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.

 * 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.

 * David Hume, Treatise of Human Nature (1739-40), Book 1: Of the understanding, Part 3, Section 16.

 * '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.
 * David Hume, Treatise of Human Nature (1739-40), Book 1: Of the understanding, Part 3, Section 16.

 * 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.
 * David Hume, Treatise of Human Nature (1739-40), Book 2: Of the passions, Part 1, Section 12.

 * '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.
 * David Hume, Treatise of Human Nature (1739-40), Book 2: Of the passions, Part 2, Section 12.

 * 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.

 * 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.

 * True human goodness, in all its purity and freedom, can come to the fore only when its recipient has no power.

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.

 * 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.

 * 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.

 * 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.

Only after the animals had had their say would his fellow creatures be called in as witnesses.

 * 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.

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.

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.

 * 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.

 * 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.

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.

 * MAN IS FUNDAMENTALLY AN ANIMAL. Animals, as distinct from man, are not machine-like, not sadistic; their societies, within the same species, are incomparably more peaceful than those of man. The basic question, then is: What has made the animal, man, degenerate into a machine? When I say "animal," I do not mean anything bad, cruel or "base"; I am stating a biological fact. Man has developed the peculiar concept that he is not an animal at all, but, well — man; a creature which long since has shed that which is "bad," which is "animal." He demarcates himself in all possible ways from the bad animal and points, in proof of his "being better," to culture and civilization which distinguish him from the animal. He shows, in his whole behavior, his "theories of values," his moral philosophies, his "monkey trials" and such, that he does not want to be reminded of the fact that basically he is an animal, an animal, furthermore, which has much more in common with the "animal" than with that being which he asserts to be and dreams of being. The theory of the German Übermensch has this origin. Man shows by his maliciousness, his inability to live in peace with his kind, his wars, that what distinguishes him from the other animals is only his unbounded sadism and the mechanical trinity of the authoritarian concept of life, mechanistic science and the machine. If one looks at the results of civilization as they present themselves over long periods of time, one finds that these contentions of man are not only erroneous; more than that, they seem to be made expressly for the purpose of making man forget that he is an animal.

 * The most striking quality that humans and animals have in common is the capacity to experience suffering. Why do we still blind ourselves, now at the beginning of the twenty-first century, to the immeasurable suffering that we inflict on animals, knowing that a great part of the pain that we cause them is neither necessary nor unavoidable? Certainly we should know that there is no moral justification for inflicting needless pain and death on any being.

 * If I am bound to do no injury to my fellow-creatures, this is less because they are rational than because they are sentient beings: and this quality, being common both to men and beasts, ought to entitle the latter at least to the privilege of not being wantonly ill-treated by the former.
 * Jean Jacques Rousseau, Discourse on Inequality (1754), translated by G. D. H. Cole, Preface.

 * The desire to protect animals derives inevitably from better acquaintance with them, from the realization that they are sensitive and intelligent creatures, affectionate and seeking affection, powerless in a cruel and incomprehensible world, exposed to all the whims of the master species. According to the animal haters, those who are fond of animals are sick people. To me it seems just the other way around, that the love for animals is something more, not something less. As a rule, those who protect animals have for them the same feeling as for all the other defenseless or abused creatures: the battered or abandoned children, the sick, the inmates of penal or mental institutions, who are so often maltreated without a way of redress. And those who are fond of animals don't love them for their "animality" but for their "humanity" — their "human" qualities. By which I mean the qualities humans display when at their best, not at their worst. Man's love for the animal is, at any rate, always inferior in intensity and completeness to the love the animal has for the human being that has won its love. The human being is the elder brother, who has countless different preoccupations, activities and interests. But to the animal that loves a human being, this being is everything. That applies not only to the generous, impetuous dog, but also to the more reserved species, with which it is more difficult to establish a relationship without personal effort and plenty of patience.

 * There is no impersonal reason for regarding the interests of human beings as more important than those of animals. We can destroy animals more easily than they can destroy us; that is the only solid basis of our claim to superiority.

But whales might value spouting, and donkeys might maintain that a good bray is more exquisite than the music of Bach. We cannot prove them wrong except by the exercise of arbitrary power.

 * Thus, because Christian morals leave animals out of consideration ... therefore in philosophical morals they are of course at once outlawed; they are merely "things," simply means to ends of any sort; and so they are good for vivisection, for deer-stalking, bull-fights, horse-races, etc., and they may be whipped to death as they struggle along with heavy quarry carts.

 * One thing that specially saddened me was that the unfortunate animals had to suffer so much pain and misery. The sight of an old limping horse, tugged forward by one man while another kept beating it with a stick to get it to the knacker's yard at Colmar, haunted me for weeks. It was quite incomprehensible to me — this was before I began going to school — why in my evening prayers I should pray for human beings only. So when my mother had prayed with me and had kissed me good-night, I used to add silently a prayer that I had composed myself for all living creatures. It ran thus: "O, heavenly Father, protect and bless all things that have breath; guard them from all evil, and let them sleep in peace."

 * Many dogs, cats and horses are loved and cherished, and are even mourned when they die. But pigs, chickens, calves and other animals grown in factory farms are treated in the most brutal and exploitative way, devoid of all affection. They are units in a production line; their only purpose is to produce the maximum amount of food at the minimum cost. Factory farms epitomize the mechanistic spirit. ... To justify this treatment, the less-favoured animals have to be regarded as inferior, unworthy of any sentimental attachment. A terrible conflict arises if the exploited animals are considered to have any value in themselves. One way to avoid this conflict is to keep the privileged and the exploited animals in separate categories in our minds. ... But if emotions spill over from pets to other animals, there is trouble. People become vegetarians, or even animal rights activists.

 * The animals themselves are incapable of demanding their own liberation, or of protesting against their condition with votes, demonstrations, or boycotts. Human beings have the power to continue to oppress other species forever, or until we make this planet unsuitable for living beings. Will our tyranny continue, proving that morality counts for nothing when it clashes with selfinterest, as the most cynical of poets and philosophers have always said? Or will we rise to the challenge and prove our capacity for genuine altruism by ending our ruthless exploitation of the species in our power, not because we are forced to do so by rebels or terrorists, but because we recognize that our position is morally indefensible? The way in which we answer this question depends on the way in which each one of us, individually, answers it.

 * Criminal history shows us how many torturers of men, and murderers, have first been torturers of animals. The manner in which a nation in the aggregate treats animals, is one chief measure of its real civilization. The Latin races, as we know, come forth badly from this examination; we Germans, not half well enough. Buddhism has done more in this direction than Christianity, and Schopenhauer more than all ancient and modern philosophers together. The warm sympathy with sentient Nature which pervades all the writings of Schopenhauer, is one of the most pleasing aspects of his thoroughly intellectual, yet often unhealthy and unprofitable philosophy.

 * To Indians the idea of the transmigration of the soul from animal to man, and man to animal, does not seem strange, and so from our scriptures pity for all sentient creatures has not been banished as a sentimental exaggeration. When I am in close touch with Nature in the country, the Indian in me asserts itself and I cannot remain coldly indifferent to the abounding joy of life throbbing within the soft down-covered breast of a single tiny bird.

 * [Concerning the love La Fontaine felt for animals] He follows their emotions, he represents their reasonings, he becomes tender, he becomes gay, he participates in their feelings. The factis, he lived in them. [...] The animals contain all the materials of man-sensations, judgments, images.

 * We can argue about their intelligence (which we would likely define in human-centric terms anyway), their ability to understand human language, or even the extent to which they really understand and know the world around them, but there's no argument that can convincingly show that animals don't feel pain, and that they have no interest in avoiding that pain. If anything, animals are more sensitive to the world around them than we are, given their heightened sensory abilities.

 * The child who has been taught to realise the claims that God's lower creatures have upon him, whose heart has been touched by lessons of kindness and mercy, under their sweet influence will grow to be a large-hearted, tender-hearted, manly man. Then let the children be trained, their hands, their intellects, and above all their hearts. Let them be taught to have pity for the animals that are at our mercy, that cannot protect themselves, that cannot explain their weakness, their pain, or their suffering, and soon this will bring to their recognition that higher law, the moral obligation of man as a superior being to protect and care for the weak and defenceless. Nor will it stop here, for this in turn will lead them to that highest law—man's duty to man.
 * Ralph Waldo Trine, Every Living Creature: Or, Heart-training Through the Animal World (New York: Thomas Y. Crowell & Co., 1899), p. 8.

 * When we study the habits of animals in a truly sympathetic way and become thoroughly acquainted with them and with the work that each one is performing, we shall see that each one has its place in the economy of God's world, that each has its part to play, and that even so far as the animal world is concerned we are all related and inter-related. If we destroy or permit to be destroyed that marvellous balance which the Divine Power has instituted in the Universe, we do it at our own peril. Instead, then, of being the enemies of the animal world, instead of being its persecutors and its destroyers, we should be its friends and helpers.
 * Ralph Waldo Trine, Every Living Creature: Or, Heart-training Through the Animal World (New York: Thomas Y. Crowell & Co., 1899), p. 64.

 * It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions.
 * Mark Twain, "What is a man?" (1906), Chapter VI: "Instinct and Thought".

 * What a pity and what a poverty of spirit, to assert that beasts are machines deprived of knowledge and sentiment, which affect all their operations in the same manner, which learn nothing, never improve, &c. [...] Some barbarians seize this dog, who so prodigiously excels man in friendship, they nail him to a table, and dissect him living, to show the mezarian veins. You discover in him all the same organs of sentiment which are in yourself. Answer me, machinist, has nature arranged all the springs of sentiment in this animal that he should not feel? Has he nerves to be incapable of suffering? Do not suppose this impertinent contradiction in nature. [...] The animal has received those of sentiment, memory, and a certain number of ideas. Who has bestowed these gifts, who has given these faculties? He who has made the herb of the field to grow, and who makes the earth gravitate towards the sun.
 * Voltaire, "Beasts", in A Philosophical Dictionary, Volume 2, J. and H. L. Hunt, 1824, p. 9.

 * There are two things for which animals are to be envied: they know nothing of future evils, or of what people say about them.
 * Voltaire, Letter (1739).

 * The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for whites or women for men.
 * Alice Walker, Foreword to The Dreaded Comparison: Animal Slavery and Human Slavery by Marjorie Spiegel (New York: Mirror Books, 1996), p. 14.

 * If it is necessary that each sentient being must have the possibility of achieving an overwhelming good, then it is clear that there must be some form of life after earthly death. Despite the many pointers to the existence of God, theism would be falsified if physical death was the end, for then there could be no justification for the existence of this world. However, if one supposes that every sentient being has an endless existence, which offers the prospect of supreme happiness, it is surely true that the sorrows and troubles of this life will seem very small by comparison. Immortality, for animals as well as humans, is a necessary condition of any acceptable theodicy; that necessity, together with all the other arguments for God, is one of the main reasons for believing in immortality.
