 * The freedom of speech and of the press which are secured by the First Amendment against abridgment by the United States are among the fundamental personal rights and liberties which are secured to all persons by the Fourteenth Amendment against abridgment by a state.

Those who won our independence had confidence in the power of free and fearless reasoning and communication of ideas to discover and spread political and economic truth. Abridgment of freedom of speech and of the press, however, impairs those opportunities for public education that are essential to effective exercise of the power of correcting error through the processes of popular government.
