“Nobody ever saw a dog make a fair and deliberate exchange of one bone for another with another dog. Nobody ever saw one animal by its gestures and natural cries signify to another, this is mine, that yours; I am willing to give this for that....But man has almost constant occasion for the help of his brethren, and it is in vain for him to expect it from their benevolence only. He will be more likely to prevail if he can interest their self-love in his favour, and show them that it is for their own advantage to do for him what he requires of them. Whoever offers to another a bargain of any kind, proposes to do this. Give me that which I want, and you shall have this which you want, is the meaning of every such offer; and it is in this manner that we obtain from one another the far greater part of those good offices which we stand in need of.”

“Man is an animal that makes bargains: no other animal does this - no dog exchanges bones with another.”

“Human needs arrange themselves in hierarchies of pre-potency. That is to say, the appearance of one need usually rests on the prior satisfaction of another, more pre-potent need. Man is a perpetually wanting animal. Also no need or drive can be treated as if it were isolated or discrete; every drive is related to the state of satisfaction or dissatisfaction of other drives. 8.”

"They told us if they kill all the lions the wildlife will disappear, so now those who become warriors are those with higher education, not those who kill lions."

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

The difference between humans and other mammals is that we know how to accessorize.

"Life is no way to treat an animal."

My homies that are around me never give me that 'star pass'. I've hung out with some stars who are playing basketball and everyone let's them score all the baskets. Shooting pool, they let them make all the shots. My homies don't let me get away with that.

If I were an animal, I would be an eagle.

"The dog has seldom been successful in pulling man up to its level of sagacity, but man has frequently dragged the dog down to his."

"The American Medical Association says the humane way is to let people starve and thirst to death. If you did that to an animal, youd be put in jail immediately ... In the face of such insanity masquerading as authority, who wouldnt be strident?"

"I was used to heat but this place was so dry the trees were bribing the dogs."

"This may be a positive thing. These animals may have moved themselves to new winter range to avoid conflicts with the wolves."

"It is quite possible that an animal has spoken to me and that I didn't catch the remark because I wasn't paying attention."

"You really can't take a cat and turn it into a dog, or try and get lemons off an apple tree, or what have you."

"Animals are my friends... and I don't eat my friends."

"I see you that have a little swimming mouse"

"I love things made out of animals. It's just so funny to think of someone saying, "I need a letter opener. I guess I'll have to kill a deer."

"Man in his arrogance thinks himself a great work, worthy of the interposition of a deity. More humble, and I believe truer, to consider him created from animals."

"Dogs and angels are not very far apart"

"I love Wagner, but the music I prefer is that of a cat hung up by its tail outside a window and trying to stick to the panes of glass with its claws."

"Kindness and compassion towards all living things is a mark of a civilized society. Conversely, cruelty, whether it is directed against human beings or against animals, is not the exclusive province of any one culture or community of people."

"We know we cannot be kind to animals until we stop exploiting them -- exploiting animals in the name of science, exploiting animals in the name of sport, exploiting animals in the name of fashion, and yes, exploiting animals in the name of food."

"If you are interested in preventing animal suffering, the first thing you should give up is eggs and milk because the animals who produce those foods lead the most unhappy lives. You would do better to eat meat and stop eating eggs and dairy products."
