Lives of great men all remind us greatness takes no easy way.
All the heroes of tomorrow are the heretics of today.
Socrates and Galileo, John Brown, Thoreau, Christ, and Debs
Heard the night cry down with traitors, and the dawn shout "Up the reds!"

As quoted in "A Tribute to Yip Harburg: The Man Who Put the Rainbow in the Wizard of Oz" at Democracy Now (25 November 2004).
