Daniel Bensen's Reviews > Extraordinary Popular Delusions and the Madness of Crowds/Confusión de Confusiones

Apparently this book is something of a classic among investors. I don't know about any of that, but MacKay's stories (published in 1841) and de La Vega's (1688) were a lot of fun. Aristocratic gambling addicts, bears, bulls, and butterflies, carriage accidents arranged by desperate ladies. A hunchback who rents himself out as a writing desk to frenzied speculators. Great research.
