Man is the only animal for whom his own existence is a problem which he has to solve and from which he cannot escape.

Animals are good to think with.

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

An ape will be an ape, though clad in purple.

Happiness is a warm puppy.

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

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

It is remarkable that only small birds properly sing.

Men, my dear, are very queer animals—a mixture of horse nervousness, ass stubbornness, and camel malice.

A good dog, sir, deserves a good bone.

Every ass thinks himself worthy to stand with the king’s horses.

If you are a dog and your owner suggests that you wear a sweater, suggest that he wear a tail.

Man and animals are really the conduit of food, the sepulcher of animals, and resting place of the dead, one causing the death of the other, making themselves the covering for the corruption of other dead bodies.
