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

Often and often afterwards, the beloved Aunt would ask me why I had never told anyone how I was being treated. Children tell little more than animals, for what comes to them they accept as eternally established.
Rudyard Kipling

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

I love very much to draw animals.
Josef Albers

Man is an exception, whatever else he is. If he is not the image of God, then he is a disease of the dust. If it is not true that a divine being fell, then we can only say that one of the animals went entirely off its head.
Gilbert K. Chesterton

Men feel that cruelty to the poor is a kind of cruelty to animals. They never feel that it is an injustice to equals; nay it is treachery to comrades.
Gilbert K. Chesterton

Animals often strike us as passionate machines.
Eric Hoffer

Fork: An instrument used chiefly for the purpose of putting dead animals into the mouth.
Ambrose Bierce

The thing that differentiates man from animals is money.
Gertrude Stein

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

History is a people's memory, and without a memory, man is demoted to the lower animals.
Malcom X

The theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men.
Bertrand Russell

How much will you give for the lives of your childrens children, which is yourself? How much are people willing to give up for air, earth, water, animals, and the coming generations? I think the answer to that is pretty clear.
Lynette Fromme

We must plant the sea and herd its animals using the sea as farmers instead of hunters. That is what civilization is all about - farming replacing hunting.
Jacques Yves Cousteau

Man, of all the animals, is probably the only one to regard himself as a great delicacy.
Jacques Yves Cousteau

The propensity to truck, barter and exchange one thing for another is common to all men, and to be found in no other race of animals.
Adam Smith

The countenances of children, like those of animals, are masks, not faces, for they have not yet developed a significant profile of their own.
W. H. Auden

I remember that. I was talking to him and I said how great it would be if actors had a tail because I have animals and a tail is so expressive. On a cat you can tell everything. You can tell if they're annoyed. You can tell whether they're scared.
Christopher Walken

Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat. If the right policies toward nature were pursued, we would need no zoos at all.
Michael J. Fox

I urge you to ask yourself just how honorable it is to preside over the abuse and suffering of animals.
Richard Pryor
