Ludwig Heinrich Edler von Mises (1881 - 1973)

A free man must be able to endure it when his fellow men act and live otherwise than he considers proper. He must free himself from the habit, just as soon as something does not please him, of calling for the police. Ludwig von Mises

Benjamin Franklin (1706 - 1790)

The best thing to give to your enemy is forgiveness; to an opponent, tolerance; to a friend, your heart; to your child, a good example; to a father, deference; to your mother, conduct that will make her proud of you; to yourself, respect; to all men, charity. Benjamin Franklin

Samuel Taylor Coleridge

I have seen great intolerance shown in support of tolerance.
Samuel Taylor Coleridge
