In this new collection of essays, F.A. Hayek traces his intellectual roots to the `Austrian school' of economics and links it to the modern rebirth of classical liberal or `libertarian' thought. There is much new interesting material here for scholars of Hayek: essays on Hayek's early life and on the intellectual climate of Vienna in the early part of the twentieth century; Hayek's opening address to the inaugural meeting of the Mont Pélerin Society and other material from the period when Hayek was playing his part in the revival of liberal thought; Hayek's views on his teachers and on other leading figures in the Austrian school.This is the fourth volume of The Collected Works of F.A. Hayek and the third to appear. This series provides a new standard edition of Hayek's writing - complete, newly ordered and comprehensively annotated. Much of the material in this volume is either previously unpublished or previously unavailable in English.
