Extraordinary Popular Delusions and the Madness of Crowds is the original guide to behavioural psychology - and how manias, follies and superstitions begin, spread and (eventually) pass. A hugely entertaining tour through financial scams and stock market bubbles, alchemical quests and prophecy wars, duelling bouts and relic hunts, the book is as insightful and memorable today as when it was first published over 150 years ago. This edition comes with an exclusive foreword by Russell Napier, author of Anatomy of the Bear. Harriman Definitive Editions offer the best quality editions of the best financial books of all time. Beautifully typeset in new designs, accompanied by forewords by the best modern financial writers, printed and bound in high-quality hardcovers on acid-free paper - they are essential long-term additions to the portfolio of every investor and trader.
