Walter Lippmann (1889–1974) was among the most influential and wide-ranging political writers in modern America. As both a journalist and political theorist, he shaped ideas about liberalism and democracy, the nature of public opinion, US power and empire, and the roles of journalists, experts, and citizens. Tom Arnold-Forster provides a bold historical reassessment of Lippmann’s intellectual life, offering fresh perspectives on a career at the intersection of daily news and democratic theory.
