Animals are in possession of themselves; their soul is in possession of their body. But they have no right to their life, because they do not will it. 

Alas! We are ridiculous animals.

Man, when perfected, is the best of animals, but when separated from law and justice, he is the worst of all. 

A good dog, sir, deserves a good bone.

Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be.

Animals, in their generation, are wiser than the sons of men, but their wisdom is confined to a few particulars, and lies in a very narrow compass.

A dog starved at his master’s gate / Predicts the ruin of the state.

The fox knows lots of tricks, the hedgehog only one—but it’s a winner.

Animals are good to think with.

Man is no man, but a wolf, to a stranger.

Man is the only animal that can remain on friendly terms with the victims he intends to eat until he eats them.

Man is merely a more perfect animal than the rest. He reasons better.

Imitate the ass in his love to his master.
