Man is no man, but a wolf, to a stranger.

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.

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.

Animals have these advantages over man: they never hear the clock strike, they die without any idea of death, they have no theologians to instruct them, their last moments are not disturbed by unwelcome and unpleasant ceremonies, their funerals cost them nothing, and no one starts lawsuits over their wills.

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

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.

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

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

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

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

Animals are such agreeable friends—they ask no questions, they pass no criticisms.

Animals are good to think with.

Who sleepeth with dogs shall rise with fleas.
