If we are not ashamed to think it, we should not be ashamed to say it.

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.

Think twice before you speak, because your words and influence will plant the seed of either success or failure in the mind of another.

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

He’s a wonderful talker, who has the art of telling you nothing in a great harangue.

A Constitution of Government once changed from Freedom, can never be restored. Liberty, once lost, is lost forever.
