Description
Charles Mackay’s seminal 1841 study explores the concept of collective folly, examining how rational individuals succumb to mass hysteria and herd mentality. The book chronicles various historical “moral epidemics,” from devastating financial manias like the Tulipmania and the South Sea Bubble, to social delusions such as witch hunts, alchemy, and the Crusades. Mackay demonstrates the timeless human propensity for irrational exuberance when driven by greed and excitement.
