The Supreme Court and the Philosopher: How John Stuart Mill Shaped US Free Speech Protections

The Supreme Court and the Philosopher illustrates how the modern US Supreme Court has increasingly adopted a view of the constitutional right to the freedom of expression that is classically liberal in nature, reflecting John Stuart Mill's reasoning in On Liberty. A landmark treatise outlining the merits of limiting governmental and social power over the individual, On Liberty advocates for a maximum protection of human freedom.

Proceeding case by case and covering a wide array of issues, such as campaign finance, offensive speech, symbolic speech, commercial speech, online expression, and false statements, Eric T. Kasper and Troy A. Kozma show how the Supreme Court justices have struck down numerous laws for infringing on the freedom of expression.

Kasper and Kozma demonstrate how the adoption of Mill's version of free speech began with Justice Oliver Wendell Holmes Jr. more than a century ago and expanded over time to become the prevailing position of the Court today. The authors argue that this embrace of Mill's rationale has led to an unmistakable reorientation in the Court's understanding of free expression jurisprudence.

The Supreme Court and the Philosopher is the first book to comprehensively explore how the political philosophy of Mill has influenced the highest court in the land. In targeting the underlying philosophical reasons that explain why the modern Supreme Court renders its First Amendment decisions, this book is particularly timely, as the issues of censorship and freedom of expression are debated in the public square today.
