Areopagitica

Areopagitica; A speech of Mr. John Milton for the Liberty of Unlicenc'd Printing, to the Parlament of England is a 1644 prose polemic by the English poet, scholar, and polemical author John Milton opposing licensing. Areopagitica is among history's most influential and impassioned philosophical defences of the principle of a right to freedom of speech and expression. Many of its expressed principles have formed the basis for modern justifications of that right.
