The US States are our laboratories of democracy.

The makers of our Constitution . . . conferred, as against the government, the right to be let alone - the most comprehensive of rights and the right most valued by civilized men.

Those who won our independence believed that the final end of the state was to make men free to develop their faculties... They valued liberty both as an end and as a means. They believed liberty to be the secret of happiness and courage to be the secret of liberty... that public discussion is a political duty; and that this should be a fundamental principle of the American government.
