The Closing of the Liberal Mind: How Groupthink and Intolerance Define the Left

The book examines the transformation of liberalism in America into a form of illiberalism, characterized by intolerance and suppression of dissent. It traces this shift back to the radical Enlightenment, which diverged from the foundational principles of American liberalism, such as individual rights and the rule of law. The author argues that contemporary liberalism has adopted authoritarian tendencies, employing tactics like speech codes and boycotts to stifle free expression. This evolution poses a significant threat to both the liberal tradition and the broader American democratic framework.
