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

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

Alas! We are ridiculous animals.

A good dog, sir, deserves a good bone.

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

Man is a troublesome animal and therefore is not very manageable.

When the eagles are silent, the parrots begin to jabber.

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.
