I love old books, especially when they're free online due to expired copyright! First published in 1841, Charles Mackay's Extraordinary Popular Delusions and the Madness of Crowds is as relevant today as it was 183 years ago.

It inspired the economist John Maynard Keynes, who argued in The General Theory of Employment (1936) that markets are not always rational, but instead are moved by "animal spirits".
