Mundo animal : Man is the only creature that consumes without producing. He does not give milk, he does not lay eggs, he is too weak to pull the plough, he cannot run fast enough to catch rabbits. Yet he is lord of all the animals. ~George Orwell, Animal Farm

Killing animals for sport, for pleasure, for adventure, and for hides and furs is a phenomena which is at once disgusting and distressing. There is no justification in indulging is such acts of brutality. - The Dalai Lama

There is no fundamental difference between man and the higher animals in their mental faculties... The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery. - Charles Darwin

Ask the experimenters why they experiment on animals, and the answer is:  "Because the animals are like us."  Ask the experimenters why it is morally okay to experiment on animals, and the answer is:  "Because the animals are not like us."  Animal experimentation rests on a logical contradiction.  ~Charles R. Magel

Pets are humanizing. They remind us we have an obligation and responsibility to preserve and nurture and care for all life. ~ James Cromwell

Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages. -- Thomas Edison

God loved the birds and invented trees.  Man loved the birds and invented cages.  ~Jacques Deval, Afin de vivre bel et bien

If a man aspires towards a righteous life, his first act of abstinence is from injury to animals.-- Albert Einstein

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.  ~William Ralph Inge

Not to hurt our humble brethren (the animals) is our first duty to them, but to stop there is not enough. We have a higher mission--to be of service to them whenever they require it... If you have men who will exclude any of God's creatures from the shelter of compassion and pity, you will have men who will deal likewise with their fellow men. -- Saint Francis of Assisi

The question is not, "Can they reason?" nor, "Can they talk?" but rather, "Can they suffer?"  ~Jeremy Bentham  YES .......THEY CAN AND THEY DO............

Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.-- Albert Einstein

I care not much for a man's religion whose dog and cat are not the better for it.  ~Abraham Lincoln

Wild animals never kill for sport. Man is the only one to whom the torture and death of his fellow creatures is amusing in itself. -- James A. Froude

Personally, I would not give a fig for any man's religion whose horse, cat and dog do not feel its benefits.  Life in any form is our perpetual responsibility.  ~S. Parkes Cadman

As custodians of the planet it is our responsibility to deal with all species with kindness, love and compassion. That these animals suffer through human cruelty is beyond understanding. Please help to stop this madness. -- Richard Gere

Ever occur to you why some of us can be this much concerned with animals suffering?  Because government is not.  Why not?  Animals don't vote.  ~Paul Harvey

Support your right to arm bears.  ~Cleveland Amory

The greatness of a nation and its moral progress can be judged by the way its animals are treated. -- Mohandas K. Gandhi

Hunting is not a sport.  In a sport, both sides should know they're in the game.  ~Paul Rodriguez

People get offended by animal rights campaigns. It's ludicrous. It's not as bad as mass animal death in a factory. -- Richard Gere

Animals give me more pleasure through the viewfinder of a camera than they ever did in the crosshairs of a gunsight.  And after I've finished "shooting," my unharmed victims are still around for others to enjoy.  I have developed a deep respect for animals.  I consider them fellow living creatures with certain rights that should not be violated any more than those of humans.  ~Jimmy Stewart

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.  ~C.S. Lewis

If only we can overcome cruelty, to human and animal, with love and compassion we shall stand at the threshold of a new era in human moral and spiritual evolution - and realize, at last, our most unique quality: humanity. ~ Jane Goodall

Michael W. Fox, vice-president of the Humane Society, said that, "to call an animal with whom you share your life a 'pet,' is reminiscent of men's magazines where you (a figure of speech, don't take it personally) have the Pet of the Month."  It is supposed that the continued use of the word "pet" to designate dogs or cats threatens to reduce their level of respect to the current status of twentieth century North American women.  Now that's radical.  ~The McGill Red Herring

Every year tens of thousands of animals suffer and die in laboratory tests of cosmetics and household products...despite the fact that the test results do not help prevent or treat accidental or purposeful misuse of the products. Please join me in using your voice for those whose cries are forever sealed behind the laboratory doors.~ Woody Harrelson

When a man wantonly destroys one of the works of man we call him a vandal.  When he destroys one of the works of god we call him a sportsman.  ~Joseph Wood Krutch

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 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. -- Ruth Harrison, author of Animal Machines

The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creatures that cannot.  ~Mark Twain, What Is Man, 1906

Instead of trying to be responsible for all the problems in the world, we should take on what we love and care about. Then we honor both our inner world and the outer world at the same time. There’s no separation between the two, and there is no hesitation, no self-doubt. This will help us develop great faith that others are taking care of their piece. People who don’t know the details about climate change may care deeply about the forests, the animals, and the children. It is very important that we share, not only our merit, but also the responsibilities. Somehow we have to relieve ourselves of the enormity, which is so debilitating.~ Paul Hawken

Until we stop harming all other living beings, we are still savages.~ Thomas Jefferson

Wild animals never kill for sport.  Man is the only one to whom the torture and death of his fellow-creatures is amusing in itself.  ~James Anthony Froude, Oceana, 1886

He who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals. -- Immanuel Kant

One day the absurdity of the almost universal human belief in the slavery of other animals will be palpable. We shall then have discovered our souls and become worthier of sharing this planet with them.-- Martin Luther King, Jr

 ask people why they have deer heads on their walls.  They always say because it's such a beautiful animal.  There you go.  I think my mother is attractive, but I have photographs of her.  ~Ellen DeGeneres

Humanity's true moral test, its fundamental test, consists of its attitude toward those who are at tis mercy: animals. And in this respect, human kind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -- Milan Kundera, The Unbearable Lightness of Being

I am in favor of animal rights as well as human rights. That is the way of a whole human being.-- Abraham Lincoln

The animals of the world exist for their own reasons.  They were not made for humans any more than black people were made for white, or women created for men.  ~Alice Walker

As often as Herman had witnessed the slaughter of animals and fish, he always had the same thought:  in their behaviour toward creatures, all men were Nazis.  The smugness with which man could do with other species as he pleased exemplified the most extreme racist theories, the principle that might is right.  ~Isaac Bashevis Singer

All beings seek for happiness; so let your compassion extend itself to all. --Mahavamsa

I would look at a dog and when our eyes met, I realized that the dog and all creatures are my family. They're like you and me. -- Ziggy Marley

The medical argument for animal testing doesn't stand up. Even if it did, I don't think we should kill other species. We think we're so much better; I'm not sure we are. I tell people, We've beaten into submission every animal on the face of the Earth, so we are the clear winners of whatever battle is going on between the species. Couldn't we be generous? I really do think it's time to get nice. No need to keep beating up on them. I think we've got to show that we're kind. -- Paul McCartney

Life is life - whether in a cat, or dog or man.  There is no difference there between a cat or a man.  The idea of difference is a human conception for man's own advantage.  ~Sri Aurobindo

Care for all the animals they need our help.Care for all the children stop thinking of ourselves, and if we work together to try for harmonysomeday we will live in peace. -- Country Joe McDonald

When I was twelve, I went hunting with my father and we shot a bird.  He was laying there and something struck me.  Why do we call this fun to kill this creature [who] was as happy as I was when I woke up this morning.  ~Marv Levy

I have always felt that the way we treat animals is a pretty good indicator of the compassion we are capable of for the human race. -- Ali McGraw

Recognize and respect Earth’s beautiful systems of balance, between the presence of animals on land, the fish in the sea, birds in the air, mankind, water, air, and land. Most importantly there must always be awareness of the actions by people that can disturb this precious balance.-- Margaret Mead

In an earlier stage of our development most human groups held to a tribal ethic.  Members of the tribe were protected, but people of other tribes could be robbed or killed as one pleased.  Gradually the circle of protection expanded, but as recently as 150 years ago we did not include blacks.  So African human beings could be captured, shipped to America and sold.  In Australia white settlers regarded Aborigines as a pest and hunted them down, much as kangaroos are hunted down today.  Just as we have progressed beyond the blatantly racist ethic of the era of slavery and colonialism, so we must now progress beyond the speciesist ethic of the era of factory farming, of the use of animals as mere research tools, of whaling, seal hunting, kangaroo slaughter and the destruction of wilderness.  We must take the final step in expanding the circle of ethics.  ~Pete Singer

The reasons for legal intervention in favour of children apply not less strongly to the case of those unfortunate slaves and victims of the most brutal part of mankind - the lower animals. -- John Stuart Mill

Animals can communicate quite well.  And they do.  And generally speaking, they are ignored.  ~Alice Walker

If you don't want to be beaten, imprisoned, mutilated, killed ot tortured, then you shouldn't condone such behaviour towards anyone, be they human or not. -- Moby

It is inexcusable for scientists to torture animals; let them make their experiments on journalists and politicians.  ~Henrik Ibsen

If you look at the course of western history you'll see that we're slowly granting basic rights to everyone. A long time ago only kings had rights. Then rights were extended to property-owning white men. Then all men. Then women. Then children. Then the mentally retarded. Now we're agonizing over the extension of basic rights to homosexuals and animals. We need to finally accept that all sentient creatures are deserving of basic rights. I define basic rights as this --the ability to pursue life without having someone else's will involuntarily forced upon you. Or, as the framers of the constitution put it, the ability to have "life, liberty and the pursuit of happiness". By what criteria can you justify denying basic rights to any living thing? Realize that by whatever criteria you employ someone could deny basic rights to you if they objected to your species, sexual preferences, color, religion, ideology etc. Would you eat your housecat, or force a mentally retarded child to ingest oven cleaner? If not, then why is it ok to eat cows and test products on sentient animals? I believe that to knowingly commit actions that cause or condone suffering is reprehensible in the extreme.I call upon you to be compassionate and treat others as you want to be treated. If you don't want to be beaten, imprisoned, mutilated, killed or tortured then you shouldn't condone such behavior towards anyone, be they human or not. -- Moby

A good deed done to an animal is as meritorious as a good deed done to a human being, while an act of cruelty to an animal is a bad as an act of cruelty to a human being.-- Prophet Mohammed

I believe in animal rights, and high among them is the right to the gentle stroke of a human hand.  ~Robert Brault

We should be evolving into a new age of business with a worldview that maintains one simple proposition—that all of nature: humans, animals, earth, are interconnected and interdependent. -- Anita Roddick

To a man whose mind is free there is something even more intolerable in the sufferings of animals than in the sufferings of man. 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.-- Romain Rolland

Whether hunting is right or wrong, a spiritual experience, or an outlet for the killer instinct, one thing it is not is a sport.  Sport is when individuals or teams compete against each other under equal circumstances to determine who is better at a given game or endeavor.  Hunting will be a sport when deer, elk, bears, and ducks are... given 12-gauge shotguns.  Bet we'd see a lot fewer drunk yahoos (live ones, anyway) in the woods if that happened.  ~R. Lerner, letter, Sierra, March-April 1991

It seems to me of great importance to teach children respect for life. Towards this end, experiments on living animals in classrooms should be stopped. To encourage cruelty in the name of science can only destroy the finer emotions of affection and sympathy, and breed an unfeeling callousness in the young towards suffering in all living creatures.-- Eleanor Roosevelt

You know, we all oppose animal cruelty. But sometimes we forget that animals on farms suffer and feel pain like all other animals. They, too, deserve to be protected from harm and cruelty. -- Charlotte Ross

Heaven is by favor; if it were by merit your dog would go in and you would stay out.  Of all the creatures ever made [man] is the most detestable.  Of the entire brood, he is the only one... that possesses malice.  He is the only creature that inflicts pain for sport, knowing it to be pain.  ~Mark Twain

Compassion for animals is intimately connected with goodness of character; and it may be confidently asserted that he who is cruel to animals cannot be a good man. --Arthur Schopenhauer

The assumption that animals are without rights, and the illusion that our treatment of them has no moral significance, is a positively outrageous example of Western crudity and barbarity. Universal compassion is the only guarantee of morality.-- Arthur Schopenhauer

The only creature on earth whose natural habitat is a zoo is the zookeeper.  ~Robert Brault

We must fight against the spirit of unconscious cruelty with which we treat the animals. Animals suffer as much as we do. True humanity does not allow us to impose such sufferings on them. It is our duty to make the whole world recognize it. Until we extend our circle of compassion to all living things, humanity will not find peace. -- Albert Schweitzer

A man is ethical only when life, as such, is sacred to him, that of plants and animals as well as that of his fellowman, and when he devotes himself helpfully to all life that is in need of help. -- Albert Schweitzer

Evolutionary biology is now uttering and seeking those forces that link us with all those that have being.  If we can discover the meaning in the trilling of a frog, perhaps we may understand why it is for us not merely noise but a song of poetry and emotion.  ~Adrian Forsyth

The thinking man must oppose all cruel customs no matter how deeply rooted in tradition and surrounded by a halo. When we have a choice, we must avoid bringing torment and injury into the life of another, even the lowliest creature; to do so is to renounce our manhood and shoulder a guilt which nothing justifies.-- Albert Schweitzer

Anyone who has accustomed himself to regard the life of any living creature as worthless is in danger of arriving also at the idea of worthless human lives.-- Albert Schweitzer

I am not interested to know whether vivisection produces results that are profitable to the human race or doesn't.... The pain which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of the enmity without looking further.  ~Mark Twain

What is man without the beasts? If all the beasts were gone, man would die from a great loneliness of the spirit. For whatever happens to the beasts, soon happens to man. All things are connected.~ Chief Seattle

Atrocities are not less atrocities when they occur in laboratories and are called medical research.-- George Bernard Shaw

The basis of all animal rights should be the Golden Rule:  we should treat them as we would wish them to treat us, were any other species in our dominant position.  ~Christine Stevens

The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them; that's the essence of humanity.-- George Bernard Shaw

Many people feel drawn to advocate for animals because even though they can feel pain and suffer just as we do, they do not have a way to advocate for their own welfare. In fact, animals are viewed by many as nothing more than property to be treated however the owner wishes. This view has created an inhumane situation for billions of animals that share our world. -- Robert Alan Silverstein

If a group of beings from another planet were to land on Earth - beings who considered themselves as superior to you as you feel yourself to be to other animals - would you concede them the rights over you that you assume over other animals?  ~Attributed to George Bernard Shaw

I know what it feels like to be hurt,and I don't want to cause that pain to any other person or creature. But somehow, in society, we numb ourselves in order to make money or to feel better about ourselves, such as with cosmetics or food. We say to ourselves, I'm going to use this animal. I'm going to say it doesn't have much worth so that I can allow myself to do these cruel things. And that just isn't fair. -- Alicia Silverstone

The animal shall not be measured by man.  In a world older and more complete than ours, they move finished and complete, gifted with extension 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 splendor and travail of the earth.  ~Henry Beston, The Outermost House, 1928

I don't have any understanding of a human being who doesn't respect the beauty of life and that goes for all creatures that have thoughts, feelings and needs. -- Alicia Silverstone

People must have renounced, it seems to me, all natural intelligence to dare to advance that animals are but animated machines.... It appears to me, besides, that [such people] can never have observed with attention the character of animals, not to have distinguished among them the different voices of need, of suffering, of joy, of pain, of love, of anger, and of all their affections.  It would be very strange that they should express so well what they could not feel.  ~Voltaire, Traité sur la tolerance

It is difficult to picture the great Creator conceiving of a program of one creature (which He has made) using another living creature for purposes of experimentation. There must be other, less cruel ways of obtaining knowledge. -- Adlai Stevenson

We should remember in our dealings with animals that they are a sacred trust to us from our heavenly Father. They are dumb and cannot speak for themselves. -- Harriet Beecher Stowe

The assumption that animals are without rights and the illusion that our treatment of them has no moral significance is a positively outrageous example of Western crudity and barbarity.  Universal compassion is the only guarantee of morality.  ~Schopenhauer

What I think about vivisection is that if people admit that they have the right to take or endanger the life of living beings for the benefit of many, there will be no limit to their cruelty.-- Leo Tolstoy

Non-violence leads to the highest ethics, which is the goal of all evolution.  Until we stop harming all other living beings, we are still savages.  ~Thomas A. Edison

It may be suggested by some books that it is not a sin to kill an animal, but it is written in our own hearts - more clearly than in any book - that we should take pity on animals in the same way as we do on humans.-- Leo Tolstoy

I am not interested to know whether vivisection produces results that are profitable to the human race or doesn't...The pain which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of the enmity without looking further. -- Mark Twain

Very little of the great cruelty shown by men can really be attributed to cruel instinct.  Most of it comes from thoughtlessness or inherited habit.  The roots of cruelty, therefore, are not so much strong as widespread.  But the time must come when inhumanity protected by custom and thoughtlessness will succumb before humanity championed by thought.  Let us work that this time may come.  ~Albert Schweitzer

Cruelty to animals is one of the most significant vices of a low and ignoble people. Wherever one notices them, they constitute a sign of ignorance and brutality which cannot be painted over even by all the evidence of wealth and luxury.-- Alexander Von Humbolt

The Animals of the planet are in desperate peril and they are fully aware of this. No less than human beings are doing in all parts of the world, they are seeking sanctuary.- Alice Walker

Because the heart beats under a covering of hair, of fur, feathers, or wings, it is, for that reason, to be of no account?  ~Jean Paul Richter

There can be no justification for causing suffering to animals simply to serve man's pleasure or simply to enhance man's lifestyle.-- The Dean of York

It came to me that every time I lose a dog they take a piece of my heart with them. And every new dog who comes into my life, gifts me with a piece of their heart. If I live long enough, all the components of my heart will be dog, and I will become as generous and loving as they are......

God made all the creatures and gave them our love and our fear,to give sign, we and they are His children, one family here.~Robert Browning

Animals have a life of their own that is of importance to them apart from their utility to us.  They are not only in the world, they are aware of it.  What happens to them matters to them.  Each has a life that fares better or worse for the one whose life it is ~Dr. Tom Regan, Animal Rights Philosopher

Deliberate cruelty to our defenceless and beautiful little cousins is surely one of the meanest and most detestable vices of which a human being can be guilty.  ~William Ralph Inge

I think how we treat our animals reflects how we treat each other ... And it's very important that we have a president who is mindful of the cruelty that is perpetrated on animals ...~Barack Obama

The indifference, callousness and contempt that so many people exhibit toward animals is evil first because it results in great suffering in animals, and second because it results in an incalculably great impoverishment of the human spirit.  All education should be directed toward the refinement of the individual's sensibilities in relation not only to one's fellow humans everywhere, but to all things whatsoever.  ~Ashley Montague

If there are no dogs in Heaven, then when I die I want to go where they went. ~Will Rogers

There will be no justice as long as man will stand with a knife or with a gun and destroy those who are weaker than he is.  ~Isaac Bashevis Singer

We can judge the heart of a man by his treatment of animals. ~Immanuel Kant

There comes a time when one must take a position that is neither safe, nor political, nor popular, but he must take it because his conscience tells him that it is right. ~ Martin Luther King

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well. ~Ralph Waldo Emerson

The life spark in my eyes is in no way different than the life spark in the eyes of any other sentient being.  ~Michael Stepaniak, quoted in Joanne Stepaniak, The Vegan Sourcebook, 1998

Animals cannot speak, but can you and I not speak for them and represent them? Let us all feel their silent cry of agony and let us all help that cry to be heard in the world. ~Rukmini Devi Arundale

Cruelty has cursed the human family for countless ages. It is almost impossible for one to be cruel to animals and kind to humans. If children are permitted to be cruel to their pets and other animals, they easily learn to get the same pleasure from the misery of fellow humans. Such tendencies can easily lead to crime. ~Fred A. Mc Gran, 1895

We must fight against the spirit of unconscious cruelty with which we treat the animals.  Animals suffer as much as we do.  True humanity does not allow us to impose such sufferings on them.  It is our duty to make the whole world recognize it.  Until we extend our circle of compassion to all living things, humanity will not find peace.  ~Albert Schweitzer, The Philosophy of Civilization

I am only one, but still I am one. I cannot do everything, but still I can do something; and because I cannot do everything, I will not refuse to do something I can do. ~Edward Everet Hale~

I looked at all the caged animals in the shelter...the cast-offs of human society. I saw in their eyes love and hope, fear and dread, sadness and betrayal. And I was angry. "God," I said, "this is terrible! Why don't you do something?" God was silent for a moment and then He spoke softly. I have done something," He replied. "I created you." ~The Animals' Savior Copyright Jim Willis 1999

If you have men who will exclude any of God's creatures from the shelter of compassion and pity, you will have men who will deal likewise with their fellow men.  ~St. Francis of Assisi

When a man wants to murder a tiger he calls it sport; when the tiger wants to murder him he calls it ferocity.  ~George Bernard Shaw

One of the most dangerous things that can happen to a child is to kill or torture an animal and get away with it". ~ Margaret Mead

Compassion is most important for happiness. We must treat fellow human beings as equal, that is very important, but also all beings who have capacity for feeling. So the innate desire for happiness that is the basis of human rights extends to all sentient beings, including animals and insects. There are now some individuals and organizations who care about animal rights and are showing concern about the suffering or torture of animals, let's co-operate, let's help..........

To educate our people, and especially our children, to humane attitudes and actions toward living things is to preserve and strengthen our national heritage and the moral values we champion in the world. ~ John Fitzgerald Kennedy

Life is as dear to the mute creature as it is to a man. Just as one wants happiness and fears pain, just as one wants to live and not to die, so do other creatures.”——His Holiness

Anyone who has accustomed himself to regard the life of any living creature as worthless is in danger of arriving also at the idea of worthless human life. ~ Albert Schweitzer

Because he has pity on every living creature, therefore is a man called ‘holy’”—Buddhism Dhammapada

If you have men who will exclude any of God's creatures from the shelter of compassion and pity, you will have men who will deal likewise with their fellow men.—Francis of Assisi

To inflict cruelties on defenseless creatures, or condone such acts, is to abuse one of the cardinal tenets of a civilized society - reverence for life. ~ Jon Evans

Animals are God’s creatures. He surrounds them with his providential care. By their mere existence they bless him and give him glory. Thus men owe them kindness. We should recall the gentleness with which saints like St. Francis of Assisi or St. Philip Neri treated 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 do we err. For the animal shall not be measured by man. They move finished and complete, gifted with the extension 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.

Animals are God's creatures, not human property, nor utilities, nor resources, nor commodities, but precious beings in God's sight…Christians whose eyes are fixed on the awfulness of crucifixion are in a special position to understand the awfulness of innocent suffering. The Cross of Christ is God's absolute identification with the weak, the powerless, and the vulnerable, but most of all with unprotected, undefended, innocent suffering....

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. . . . They have the right not to be brutalized in any way as food resources, for entertainment or any other purpose.

Animals have done us no harm and they have no power of resistance.…There is something so very dreadful…in tormenting those who have never harmed us, who cannot defend themselves, who are utterly in our power.

Animals do not survive by rational thought (nor by sign languages allegedly taught to them by psychologists). They survive through inborn reflexes and sensory-perceptual association. They cannot reason. They cannot learn a code of ethics. A lion is not immoral for eating a zebra (or even for attacking a man). Predation is their natural and only means of survival; they do not have the capacity to learn any other. Edwin A. Locke

Not to hurt our humble brethren is our first duty to them, but to stop there is not enough. We have a higher mission—to be of service to them wherever they require it.—Francis of Assisi

Animals, as part of God’s creation, have rights which must be respected.  It behooves us always to be sensitive to their needs and to the reality of their pain.

In studying the traits and dispositions of the so-called lower animals, and contrasting them with man's, I find the result humiliating to me.--Mark Twain

The obligations of law and equity reach only to mankind; but kindness and beneficence should be extended to the creatures of every species, and these will flow from the breast of a true man, as streams that issue from the living fountain.—Plutarch

The time will come when men such as I will look upon the murder of animals as they now look on the murder of men.― Dmitry Merezhkovsky

Animals share with us the privilege of having a soul.”—Pythagoras

Know that the same spark of life that is within you, is within all of our animal friends, the desire to live is the same within all of us..― Rai Aren

Our task must be to free ourselves— by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.—Albert Einstein

He who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals..

The fate of animals is of greater importance to me than the fear of appearing ridiculous.—Emile Zola

For fidelity, devotion, love, many a two-legged animal (man) is below the dog and the horse. Happy would it be for thousands of people if they could stand at last before the Judgment Seat and say "I have loved as truly and I have lived as decently as my dog." And yet we call them "only animals"!"   --Henry Ward Beecher

True benevolence or compassion, extends itself through the whole of existence and sympathizes with the distress of every creature capable of sensation.-- Joseph Addison

Love animals: God has given them the rudiments of thought and joy untroubled. Do not trouble their joy, don't harass them, don't deprive them of their happiness, don't work against God's intent. Man, do not pride yourself on superiority to animals; they are without sin, and you, with your greatness, defile the earth by your appearance on it, and leave the traces of your foulness after you--alas, it is true of almost everyone of us!"    --Fyodor Dostoyevsky

Life is life's greatest gift. Guard the life of another creature as you would your own because it is your own. On life's scale of values, the smallest is no less precious to the creature who owns it than the largest.-- Lloyd Biggle Jr.

All cruelty springs from weakness-- Seneca

Love of animals is a universal impulse, a common ground on which all of us may meet. By loving and understanding animals, perhaps we humans shall come to understand each other.-- Louis J. Camuti

Love of animals is a universal impulse, a common ground on which all of us may meet. By loving and understanding animals, perhaps we humans shall come to understand each other. --Dr Louis J.Camuti

Until we have the courage to recognize cruelty for what it is--whether its victim is human or animal--we cannot expect things to be much better in this world... -- Rachel Carson

We cannot have peace among men whose hearts 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

It should not be believed that all beings exist for the sake of the existence of man. On the contrary, all the other beings too have been intended for their own sakes and not for the sake of anything else.--Maimonides

The brute animals have all the same sensations of pain as human beings, and consequently endure as much pain when their body is hurt; but in their case the cruelty of torment is greater, because they have no mind to bear them up against their sufferings, and no hope to look forward to when enduring the last extreme pain.-- Thomas Chalmers

The soul is the same in all living creatures, although the body of each is different. -Hippocrates
