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.

The elephant, although a gross beast, is yet the most decent and most sensible of any other upon earth. Although he never changes his female, and hath so tender a love for her whom he hath chosen, yet he never couples with her but at the end of every three years, and then only for the space of five days.

Who hears the fishes when they cry?

It is remarkable that only small birds properly sing.

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

One of the animals which a generous and sociable man would soonest become is a dog. A dog can have a friend; he has affections and character; he can enjoy equally the field and the fireside; he dreams, he caresses, he propitiates; he offends and is pardoned; he stands by you in adversity; he is a good fellow.

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.

Keep running after a dog, and he will never bite you.

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

A good dog, sir, deserves a good bone.

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?

Who sleepeth with dogs shall rise with fleas.
