This is a "new" book by Ludwig von Mises, the first of a series of lecture transcripts drawn from careful notes taken by Bettina Bien Greaves in the summer of 1951. It features Mises in a role in which we do not usually find him, not as a writer but as a speaker of enormous erudition and power.

There are nine lectures in this book: Economics and its Opponents; Pseudo-Science and Historical Understanding; Acting Man and Economics; Marxism, Socialism, and Pseudo-Science; Capitalism and Human Progress; Money and Inflation; The Gold Standard: Its Importance and Restoration; Money, Credit, and the Business Cycle; and The Business Cycle and Beyond.

If one has doubts about the method by which this book came about, it only takes a quick glance to see that these must be very faithful renderings of what he said in his famous New York seminar. The brilliance, determination, and unique Misesian perspective are all here.

Plus, we find him commenting on matters one usually doesn't find in his others books, such as the impact that Plato had on the classical world, the place of Rousseau in history, the role of liberalism on the Continent as versus England, the impact of Poincare and Einstein, as well as passing comments on everything from banking debates of the 19th century as well as the role of ideology in modern life.

A thrilling aspect of the book is how one can almost hear Mises speaking as you read through the prose. The reader senses that he or she is right there in the room with Mises as professor and teacher, generously sharing his reflections on theory, history, and politics.
