Areopagitica

Areopagitica; A speech of Mr. John Milton for the Liberty of Unlicenc’d Printing, to the Parlament of England is a 1644 prose polemical tract by the English poet and polemical author John Milton opposing licensing and censorship. Areopagitica is among history's most influential and impassioned philosophical defences of the principle of a right to freedom of speech and expression. It is regarded as one of the most eloquent defences of press freedom ever written because many of its expressed principles form the basis for modern justifications of that right.
