The ultimate touchstone of constitutionality is the Constitution itself, and not what we have said about it.
Felix FrankfurterFreedom of expression is the well-spring of our civilization... The history of civilization is in considerable measure the displacement of error which once held sway as official truth by beliefs which in turn have yielded to other truths. Therefore the liberty of man to search for truth ought not to be fettered, no matter what orthodoxies he may challenge.
Felix FrankfurterFreedom of speech and of the press are essential to the enlightenment of a free people and in restraining those who wield power.
