Be a good animal, true to your animal instincts.

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

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.

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.

Who sleepeth with dogs shall rise with fleas.

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. 

Do you not see how God is praised by those in the heavens and those on earth? The very birds praised Him as they wing their way.

Of all the creatures that breathe and creep on the surface of the earth, none is more to be pitied than man.

Every creature in the world is like a book and a picture, to us, and a mirror.

There are some who, if a cat accidentally comes into the room, though they neither see it nor are told of it, will presently be in a sweat and ready to die away.

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.

The righteous know the needs of their animals, but the mercy of the wicked is cruel.

I do not mean to call an elephant a vulgar animal, but if you think about him carefully, you will find that his nonvulgarity consists in such gentleness as is possible to elephantine nature—not in his insensitive hide, nor in his clumsy foot, but in the way he will lift his foot if a child lies in his way; and in his sensitive trunk, and still more sensitive mind, and capability of pique on points of honor.
