Nothing shows a man's character more than what he laughs at.

There is nothing in which people more betray their character than in what they laugh at.

Men show their character in nothing more clearly than what they think laughable.

A man's manners are a mirror in which he shows his portrait.

Nothing is more terrible than to see ignorance in action.

There is nothing in the world more shameful than establishing one's self on lies and fables.
