Areopagitica

"Areopagitica" is a philosophical pamphlet written by John Milton in 1644 advocating for freedom of speech and expression. In it, Milton argues against censorship and the licensing of published works, asserting that open discourse is essential for truth and knowledge to flourish. He compares the pursuit of truth to a marketplace of ideas where only through debate and discussion can people discern the best thoughts. "Areopagitica" is considered a foundational text for later discussions on free speech and remains influential in debates about the regulation of ideas and information.
