Commit a crime, and the earth is made of glass. - Ralph Waldo Emerson

Only the great generalizations survive. The sharp words of the Declaration of Independence, lampooned then and since as 'glittering generalities,' have turned out blazing ubiquities that will burn forever and ever.

Speak what you think now in hard words and tomorrow speak what tomorrow thinks in hard words again, though it contradicts everything you said today.

Every revolution was first a thought in one man's mind, and when the same thought occurs to another man, it is the key to that era.
