Extraordinary Popular Delusions and the Madness of Crowds
First published in 1841. The book chronicles its targets in three parts: "National Delusions", "Peculiar Follies", and "Philosophical Delusions". The subjects of Mackay's debunking include alchemy, beards (influence of politics and religion on), witch-hunts, crusades and duels. Present day writers on economics, such as Andrew Tobias and Michael Lewis, laud the three chapters on economic bubbles.
