There be beasts that, at a year old, observe more, and pursue that which is for their good more prudently, than a child can do at ten.

Imitate the ass in his love to his master.

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

Be a good animal, true to your animal instincts.

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

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.

Animals are good to think with.

A bull contents himself with one meadow, and one forest is enough for a thousand elephants; but the little body of a man devours more than all other living creatures.

Who sleepeth with dogs shall rise with fleas.

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

We call them dumb animals, and so they are, for they cannot tell us how they feel, but they do not suffer less because they have no words.

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. 

I hate the sight of monkeys; they remind me so of poor relations.
