For centuries, humans have been torturing animals for personal gain. These actions have often been excused as necessary, for getting food, advancing technology, or boosting trade.

But the most disturbing cruelty is the kind carried out purely for fashion, sport, or fun, like canned hunting. The people who speak up against this cruelty are our saving grace. Here are some powerful quotes from a few of them.

Famous Quotes on Animal Abuse

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, American Inventor and Scientist
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, German Philosopher
We have enslaved the rest of animal creation and have treated our distant cousins in fur and feathers so badly that beyond doubt, if they were to formulate a religion, they would depict the Devil in human form.
William Ralph Inge, British Author
For as long as men massacre animals, they will kill each other. Indeed, he who sows the seed of murder and pain cannot reap joy and love.
Pythagoras, Greek Philosopher
Show me the enforced laws of a state for the prevention of cruelty to animals and I in turn will give you a correct estimate of the refinement, enlightenment, integrity and equity of that commonwealth's people.

He who harms animals has not understood or renounced deeds of sin ... Those whose minds are at peace and who are free from passions do not desire to live at the expense of others.
Sourced from Acharanga Sutra (Jainism - Non-Vedic Religion of Old India)
The awful wrongs and sufferings forced upon the innocent, helpless, faithful animal race form the blackest chapter in the whole world's history.
Edward Freeman, English Historian and Commentator
Nothing living should ever be treated with contempt. Whatever it is that lives, a man, a tree, or a bird, should be touched gently, because the time is short. Civilization is another word for respect for life ...
Elizabeth Goudge (Author)
I hope to make people realize how totally helpless animals are, how dependent on us, trusting as a child must that we will be kind and take care of their needs ... [they] are an obligation put on us, a responsibility we have no right to neglect, nor to violate by cruelty.
James Herriot, English Veterinarian and Author
A young piglet with trusting eyes
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, American Actor
Cruelty to dumb animals is one of the distinguishing vices of low and base minds. Wherever it is found, it is a certain mark of ignorance and meanness; a mark which all the external advantages of wealth, splendor, and nobility, cannot obliterate. It is consistent neither with learning nor true civility.
William Jones, English Philologist and Jurist
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, Alsatian Theologian, Musician, and Medical Missionary
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.
Dr. Jon Evans
Our treatment of animals is important to our own internal state. If we are to expand our horizons, to grow to understand what the relatedness of each and every thing means, then our love and appreciation of all life is essential. Our respect and reverence for all living things will be reflected in our own living.
Bill Schul, Author of The Psychic Power of Animals
If a man aspires toward a righteous life, his first act of abstinence is from injury to animals.
Leo Tolstoy, Russian Novelist and Philosopher
Our treatment of animals will someday be considered barbarous. There cannot be perfect civilization until man realizes that the rights of every living creature are as sacred as his own.
Dr. David Starr Jordan, American Biologist and Educator
We cannot have peace among men whose hearts find delight in killing any living creature.
Rachel Carson, American Author and Marine Biologist
We cannot glimpse the essential life of a caged animal, only the shadow of its former beauty.
Julia Allen Field
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, American Actress
The time will come when men such as I will look upon the murder of animals as they now look upon the murder of men.
Leonardo da Vinci, Italian Painter, Sculptor, Architect, Musician, Engineer, and Scientist
Murderers ... very often start out by killing and torturing animals as kids.
Robert K. Ressler, Former FBI Serial Killer Profiler
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, Roman Catholic friar, founder of the Franciscan Order
These birds and animals and fish cannot speak, but they can suffer, and our God who created them, knows their sufferings, and will hold him who causes them to suffer unnecessarily to answer for it. It is a sin against their Creator.
George Q. Cannon, Animal Activist

Famous Quotes on Animal Rights

Many of the world's greatest thinkers have linked animal rights to the moral health of a whole society. If we treat those who cannot fight back with contempt, what does that say about us?

Human liberation will begin when we understand that our evolution and fulfillment are contingent on the recognition of animal rights and on a compassionate and responsible stewardship of nature.
Dr. Michael W. Fox, Animal Activist
The greatness of a nation and its moral progress can be judged by the way its animals are treated.
Mahatma Gandhi, Indian Statesman and Philosopher
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 towards 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.
Milan Kundera, Czech Novelist
Most people have forgotten how to live with living creatures, with living systems and that, in turn, is the reason why man, whenever he comes into contact with nature, threatens to kill the natural system in which and from which he lives.
Konrad Lorenz, Naturalist
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.

Animal Testing Quotes

A person holding a sign against animal testing, representing public opposition to laboratory animal cruelty
Public voices against animal cruelty in laboratories have grown louder each decade.
Atrocities are no less atrocities when they occur in laboratories and are called 'medical research.'
George Bernard Shaw, Irish Playwright and Critic
It is totally unconscionable to subject defenseless animals to mutilation and death, just so a company can be the first to market a new shade of nail polish or a new, improved laundry detergent ... It's cruel, it's brutal, it's inhumane, and most people don't want it.
Abigail 'Dear Abby' Van Buren
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 (Former First Lady of the USA)
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, Actor
I abhor vivisection. It should at least be curbed. Better, it should be abolished. I know of no achievement through vivisection, no scientific discovery, that could not have been obtained without such barbarism and cruelty. The whole thing is evil.
Dr. Charles Mayo, Founder of the Mayo Clinic
A white laboratory rabbit in a small cage

The Animal Welfare Act outlaws animal cruelty, but cruelty still exists in many direct and indirect forms.

What gives real hope is that, in recent years, more and more people have been speaking out against these wrongs. And their outrage is not just words. It is backed up by action too.
