A Kirkus Reviews Best Nonfiction Book of the Year: “Fascinating . . . A magnificent book about a magnificent moment in American legal history.” —The Atlantic

A Winner of the Robert F. Kennedy Book Award

No right seems more fundamental to American public life than freedom of speech. Yet well into the twentieth century, that freedom was still an unfulfilled promise, with Americans regularly imprisoned merely for speaking out against government policies. Indeed, free speech as we know it comes less from the First Amendment than from a most unexpected source: Supreme Court justice Oliver Wendell Holmes. A lifelong skeptic, he disdained individual rights, including the right to express one’s political views. But in 1919, it was Holmes who wrote a dissenting opinion that would become the canonical affirmation of free speech in the United States.

Why did Holmes change his mind? That question has puzzled historians for almost a century. Now, with the aid of newly discovered letters and confidential memos, law professor Thomas Healy reconstructs in vivid detail Holmes’s journey from free-speech opponent to First Amendment hero. It is the story of a remarkable behind-the-scenes campaign by a group of progressives to bring a legal icon around to their way of thinking—and a deeply touching human narrative of an old man saved from loneliness and despair by a few unlikely young friends.

Beautifully written and exhaustively researched, The Great Dissent is intellectual history at its best, revealing how free debate can alter the life of a man and the legal landscape of an entire nation.

“Compelling [and] charming.” —The Wall Street Journal

“A beautifully written history, capturing the lively and passionate debate as Holmes came to see the abiding imperative of free speech and defend it at great cost to his own reputation at the time.” —Booklist

“A stirring mix of intelligent biography and truly significant social and legal history.” —TheChristian Science Monitor
