Many years ago, I took a graduate seminar on John Milton centered on Paradise Lost (1667), one of the crowning achievements of the English Renaissance. But it was another work—Areopagitica (1644), his impassioned defense of freedom of speech—that has resonated with me ever since.
Written in opposition to Parliament’s Licensing Order, Milton argued that truth is strengthened, not endangered, by being tested against error, a bold stance in an age when dissent could invite imprisonment or execution.
Milton’s intellectual hero was Galileo. In Paradise Lost, he evokes the great astronomer when describing Satan’s massive shield:
“…the moon, whose orb
Through optic glass the Tuscan artist views…”
The “Tuscan artist” is Galileo, whose telescope transformed humanity’s understanding of the heavens.
In Areopagitica, Milton recalls visiting Galileo at his villa in Arcetri, where the aging scientist lived under house arrest after being condemned by the Roman Inquisition for advocating the Copernican model of the solar system.
Forced under threat of torture to recant what he knew to be true, Galileo spent his final years blind and confined. I like to imagine that Milton’s visit offered some measure of consolation to a man whose only offense had been to follow the evidence where it led.
Today, speaking one’s conscience seldom risks imprisonment in liberal democracies, but it can still carry severe consequences: reputational ruin, professional ostracism, organized harassment, and targeted campaigns intended to silence rather than engage.
Public discourse, accelerated by social media, spreads these consequences with astonishing speed, rewarding denunciation far more readily than disagreement.
Our universities bear part of this responsibility. Among the intellectual influences that have shaped portions of academic life is Marxist philosopher Herbert Marcuse, mentor of the New Left. In his 1965 essay Repressive Tolerance, Marcuse proposed a striking inversion of classical free expression:
“Liberating tolerance, then, would mean intolerance against movements from the Right, and toleration of movements from the Left.”
He made the practical implications explicit, advocating for the “withdrawal of tolerance before the deed, at the stage of communication in word, print, and picture.”
In Marcuse’s view, there are issues where “certain ideas cannot be expressed, certain policies cannot be proposed.”
Whether one agrees with Marcuse or not, his framework represents a profound departure from Milton’s conviction that truth emerges through open contest rather than enforced orthodoxy.
I have no dog in today’s culture wars. Censorship has become an equal-opportunity temptation for both the Left and the Right. Battles over gender, sexuality, race, religion, history, and politics have produced book bans, withdrawn publications, disinvited speakers, removed art, renamed institutions, and ousted educators. The particulars vary; the impulse to silence does not.
Milton himself understood the cost of dissent. Like Galileo, he eventually lost his sight. Following his death in 1674, he was denied burial in Westminster Abbey’s Poets’ Corner due to his support for the Parliamentary cause during the English Civil War. Buried instead at St. Giles Cripplegate, his grave was desecrated more than a century later by souvenir hunters who carried away portions of his bones as grisly relics.
Some may dismiss Milton’s model as anachronistic, but I remain convinced that falsehood is exposed by argument, not by prohibition. The remedy for bad ideas remains better ideas, fearlessly expressed.
History offers sobering reminders of what happens when enforced orthodoxy replaces open debate. Authoritarian regimes throughout history have always understood that controlling speech is the prerequisite to controlling thought.
America has never perfectly reconciled its ideals with its practice, which is precisely why freedom of speech remains indispensable.
We improve our republic not by silencing one another, but by arguing honestly, listening seriously, and trusting that truth has nothing to fear from debate.
As Milton wrote in Areopagitica nearly four centuries ago:
“And though all the winds of doctrine were let loose to play upon the earth, so Truth be in the field, we do injuriously, by licensing and prohibiting, to misdoubt her strength. Let her and Falsehood grapple; who ever knew Truth put to the worse, in a free and open encounter?”
