You shall learn to laugh. Now, all higher humor begins with this, that one no longer takes one's person seriously.
Good sense and genius beget esteem and regard: Wit and humour excite love and affection.
Humor is mankind's greatest blessing.
Humor has no aim; irony always has an idea behind it.
Just as true humor is laughter at oneself, true humanity is knowledge of oneself.
Now, true humor begins when a man ceases to take himself seriously.
Humor is the first of the gifts to perish in a foreign tongue.
Everything human is pathetic. The secret source of humor itself is not joy but sorrow. There is no humor in heaven.
Irony hurts, humour treats. Irony can kill; humour helps to live. Irony wants to establish domination; humour liberates. Irony is cruel, humor is forgiving. Irony is humiliating; humor is humble.
