This article examines the intellectual relationship between Friedrich Hayek and Walter Lippmann in the 1930s and 1940s, and argues that Lippmann's writings on economic planning were a neglected influence on the development of Hayek's political thought in this period. Lippmann's work provided a first approximation of arguments that Hayek would later make this own: that planning would destroy civil and political freedom; that a certain form of legal order was essential to the preservation of liberty; and that critics of planning should offer a positive liberal reform agenda that was compatible with this understanding of the law.
