Alas! We are ridiculous animals.

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

Histories are more full of examples of the fidelity of dogs than of friends.

What delight can there be, and not rather displeasure, in hearing the barking and howling of dogs? Or what greater pleasure is there to be felt when a dog followeth a hare than when a dog followeth a dog?

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

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. 

Who sleepeth with dogs shall rise with fleas.

Imitate the ass in his love to his master.

In every man is a wild beast; most of them don’t know how to hold it back, and the majority give it full rein when they are not restrained by terror of law.

Go to the ant, you lazybones; consider its ways, and be wise.

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

Be a good animal, true to your animal instincts.

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