—Chatham House

"Freedom of speech has fallen out of favor, now frequently associated with right-wing talking points. But here, in this nuanced outing, California human rights lawyer Eric Berkowitz gives the subject the consideration it’s due. He traces the history of attacks on free speech and explores why societies censor dissenting ideas."
—The Globe and Mail

“A timely contribution to an ongoing debate.”
—Kirkus Reviews

“[A] thought-provoking account . . . Berkowitz segues fluidly between historical eras and marshals a plethora of intriguing case studies. Readers will be convinced that policing harmful rhetoric too aggressively ‘will cause worse mischief in the long run.’”
—Publishers Weekly

—New York Review of Books

“I have never read a more comprehensive, entertaining historical account of censorship in the West.”
—Greg Lukianoff, The FIRE (The Foundation for Individual Rights in Education)

“Free speech good! Censorship bad! Undeniable. Indisputable. Except that Eric Berkowitz denies and disputes with such intellectual agility as to induce cramping of the brain. Vivid, violent historical examples buttress the case against censorship, while we citizens of the Internet find ourselves drowning in crud for want of it. The point is you’ll enjoy the ride, and the argument has never been more pressing.”
—Ted Koppel

“Berkowitz untangles censorship’s maddening complexities to reveal core truths behind every book burning, every silencing of dissidents, and every removal of online content. . . . Dangerous Ideas takes the reader on an unruly ride—from the Vatican’s infamous list of banned books to algorithms that manipulate online speech to modern demands for safe spaces from offense. A hugely entertaining and urgently important book.”
—Nadine Strossen, former president of the ACLU and author of Hate: Why We Should Resist It with Free Speech, Not Censorship

“Eric Berkowitz has written a magnificent book that is original in its scope. . . . Beautifully written, this book leaves the reader with the strong sense that in every society there is the impulse to censor, but censorship rarely works.”
—Erwin Chemerinsky, dean, UC Berkeley School of Law, and author of The Case Against the Supreme Court

“The sweep of this book is vast and its judgments thoughtful. Above all, Berkowitz shows that censorship remains tempting for those in power, even as history demonstrates how often it proves futile.”
—Richard Tofel, president, ProPublica

“Unorthodox ideas can be dangerous enough to provoke censorship. Forbidden truths lurk in the shadows of taboo. With impressive scholarship and erudite humor, Eric Berkowitz guides the reader through mental spaces that have been declared off-limits from the ancient world to the present. Read this book before it’s banned.”
—Christopher Ryan, coauthor of Sex at Dawn

“A lively, engaging, and thoughtful history of the complex evolution of free speech . . . Berkowitz brings to life the most exciting and compelling controversies over free speech in the history of the Western world.”
