230 years ago, in his Age of Reason, Thomas Paine implored his fellow Americans to break free of the mental prison imposed on them by monarchs and priests and to embrace a mental freedom found in reason.

As Bob Marley sang, "Free yourselves from mental slavery, none but ourselves can free our minds."
