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

“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.”

“We talk of wild animals but man is the only wild animal. It is man that has broken out. All other animals are tame animals; following the rugged respectability of the tribe or type.”

“Although other animals may be different from us, this does not make them LESS than us”

“Civilized" society is a hopeful belief and protest that science, money and goods make man count for more than any other animal. In this sense everything that man does is religious and heroic, and yet in danger of being fictitious and fallible,”

“Incredible the animal that first dreamed of another animal.”
