If America is to be run by the people, it is the people who must think. And we do not need to put on sackcloth and ashes to think. Nor should our minds work like a sundial which records only sunshine. Our thinking must square against some lessons of history, some principles of government and morals, if we would preserve the rights and dignity of men to which this nation is dedicated.
