Extraordinary popular delusions and the madness of crowds

‘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 almost 180 years ago.
