A poet can survive everything but a misprint.

All men make mistakes, but a good man yields when he knows he knows his course is wrong and repairs the evil. The only crime is pride.

Those who profess to favor freedom, and yet deprecate agitation, are men who want crops without plowing up the ground, they want rain without thunder and lightning. They want the ocean without the awful roar of its many waters.

Sleep that masters all.

With integrity, you have nothing to fear, since you have nothing to hide.

In school, you are given the lesson first. One the street, you're given the mistake first and then it's up to you to find the lesson, if you ever find it.

Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations.

Mistakes are a fact of life. It is the response to error that counts.

Be bold. If you're going to make an error, make a doozy, and don't be afraid to hit the ball.

There is nothing so absurd or ridiculous that has not at some time been said by some philosopher.

Feelings of worth can flourish only in an atmosphere where individual differences are appreciated, mistakes are tolerated, communication is open, and rules are flexible. The kind of atmosphere that is found in a nurturing family.

Understanding a question is half an answer.

When angry, count to ten before you speak; if very angry, one hundred.

The world would be happier if men had the same capacity to be silent that they have to speak.

The right to free speech is more important than the content of the speech.

Remember not only to say the right thing in the right place, but far more difficult still, to leave unsaid the wrong thing at the tempting moment.

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or the right of the people to peacefully to assemble, and to petition the government for a redress of grievances. -First Amendment

The thought of only being a creature of the present and the past was troubling. I longed for a future, too, with hope in it. The desire to be free, awakened my determination to act, to think, and to speak.

The truth is always exciting. Speak it, then. Life is dull without it.

Teach your child to hold his tongue; he'll learn fast enough to speak.

Silence at the proper season is wisdom, and better than any speech.
