Karl Popper and Friedrich von Hayek are remembered as two of the twentieth century’s greatest proponents of open society. However, over the years, Hayek’s ideas have tended to be favoured over Popper’s in both academic and political discussions. This book aims to improve understanding of Popper’s and Hayek’s philosophies by explaining their differences, and whilst doing so, to encourage liberal political philosophers to take a better-informed and more sympathetic look at Popper’s ideas about open society. Popper and Hayek differed in subtle but fundamental ways about rationality, economism, and democracy. They thus differed about whether and to what extent society is well served by deliberate attempts at social engineering and government intervention in the economy. They also differed about whether democracy is better served by institutions designed to elect the best leaders, or by institutions designed to protect us against the leaders we elect. And they differed, perhaps most importantly, about whether we should value freedom as a means to prosperity or an end-in-itself. This book argues that Hayek’s views about rationality, economism, and democracy are fundamentally at odds with Popper’s3⁄4 and perhaps even with open society itself—and that the unintended consequences of Hayek’s views may actually pose a threat to Popper’s vision of a liberal and free open society.

This book compares Karl Popper and Friedrich Hayek systematically and critically assessing their contribution to the political philosophy of the Open Society and is controversial in that they are defended in areas where they are usually criticized.

Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

A 2022 Economist Best Book of the Year. The definitive account of the distinguished economist’s formative years. Few twentieth-century figures have been lionized and vilified in such equal measure as Friedrich Hayek—economist, social theorist, leader of the Austrian school of economics, and champion of classical liberalism. Hayek’s erudite arguments in support of individualism and the market economy have attracted a devout following, including many at the levers of power in business and government. Critics, meanwhile, cast Hayek as the intellectual forefather of “neoliberalism” and of all the evils they associate with that pernicious doctrine. In Hayek: A Life, historians of economics Bruce Caldwell and Hansjörg Klausinger draw on never-before-seen archival and family material to produce an authoritative account of the influential economist’s first five decades. This includes portrayals of his early career in Vienna; his relationships in London and Cambridge; his family disputes; and definitive accounts of the creation of The Road to Serfdom and of the founding meeting of the Mont Pèlerin Society. A landmark work of history and biography, Hayek: A Life is a major contribution both to our cultural accounting of a towering figure and to intellectual history itself.

From a Nobel Laureate economist, a collection of essays outlining ideas on political theory, economic freedom and epistemology. Following on F. A. Hayek’s previous work Studies in Philosophy, Politics, and Economics (1967), New Studies in Philosophy, Politics, Economics and the History of Ideas collects some of Hayek’s most notable essays and lectures dealing with problems of philosophy, politics and economics, with many of the essays falling into more than one of these categories. Expanding upon the previous volume the present work also includes a fourth part collecting a series of Hayek’s writings under the heading “History of Ideas.” Of the articles contained in this volume the lectures on “The Errors of Constructivism”and “Competition as a Discovery Procedure” have been published before only in German, while the article on “Liberalism” was written in English to be published in an Italian translation in the Enciclopedia del Novicento by the Istituto della Enciclopedia Italiana at Rome.

F. A. Hayek (1899–1992) was among the most important economists and political philosophers of the twentieth century. He is widely regarded as the principal intellectual force behind the triumph of global capitalism, an 'anti-Marx' who did more than any other recent thinker to elucidate the theoretical foundations of the free market economy. His account of the role played by market prices in transmitting economic knowledge constituted a devastating critique of the socialist ideal of central economic planning, and his famous book The Road to Serfdom was a prophetic statement of the dangers which socialism posed to a free and open society. He also made significant contributions to fields as diverse as the philosophy of law, the theory of complex systems, and cognitive science. The essays in this volume, by an international team of contributors, provide a critical introduction to all aspects of Hayek's thought.
