It provides critical context for current debates on censorship, hate speech, and digital platform regulation, making it essential for understanding the historical and modern stakes of free expression.

Jacob Mchangama is a Danish lawyer, founder of the think tank Justitia, and a Vanderbilt University research professor. A global free speech expert, he hosts the podcast Clear and Present Danger and contributes to media like The Economist and The Washington Post. His work focuses on defending civil liberties in democratic and authoritarian regimes.

Mchangama argues that free speech underpins intellectual and societal progress but remains perpetually threatened by power structures. He demonstrates how restrictions often escalate during crises, cites historical victories (e.g., the abolition of blasphemy laws), and warns against modern overregulation of online speech, which risks repeating past mistakes.

It critiques social media platforms for enabling disinformation while emphasizing that censorship is ineffective and dangerous. Mchangama advocates for transparency and accountability without stifling dissent, noting that authoritarian regimes exploit content moderation tools to suppress criticism.

Wells, First Amendment advocate Oliver Wendell Holmes Jr., and Nelson Mandela, who linked free speech to anti-apartheid efforts.

Yes. The book details censorship methods across eras: ancient ruler-worship laws, medieval heresy prosecutions, colonial-era sedition acts, and modern “fake news” crackdowns. Mchangama shows how elites weaponize censorship to maintain power, often exacerbating societal tensions.

He warns that democracies are backsliding through laws targeting hate speech, misinformation, and online extremism. While acknowledging real harms, he argues such measures often empower authoritarianism. The book urges vigilance to protect free expression as a cornerstone of equality and innovation.

The book underscores that free speech fosters progress but requires constant defense. Key takeaways:

• censorship fuels repression
• marginalized groups benefit most from open discourse
• combating harmful speech requires counter-speech—not suppression

Unlike narrower legal analyses, Mchangama’s work spans millennia and continents, blending historical narrative with modern relevance. It complements works like Timothy Garton Ash’s Free Speech by emphasizing global perspectives and digital-age challenges.

As debates over AI moderation, deepfakes, and global authoritarianism intensify, the book provides a framework to evaluate policies. Its historical parallels help readers discern between legitimate regulation and threats to civil liberties, ensuring informed advocacy for open societies.
