Extraordinary Popular Delusions and The Madness of Crowds Quotes

“The study of the errors into which great minds have fallen in the pursuit of truth can never be uninstructive. . . No man is so wise but that he may learn some wisdom from his past errors, either of thought or action, and no society has made such advances as to be capable of no improvement from the retrospect of its past folly and credulity.”

“An enthusiastic philosopher, of whose name we are not informed, had constructed a very satisfactory theory on some subject or other, and was not a little proud of it. "But the facts, my dear fellow," said his friend, "the facts do not agree with your theory."—"Don't they?" replied the philosopher, shrugging his shoulders, "then, tant pis pour les faits;"—so much the worse for the facts!”

“Toda era tem sua loucura peculiar; algum plano, projeto ou fantasia em que mergulha, estimulada pelo amor do ganho, pela necessidade de emoção ou pela simples força da imitação. Se tudo isso falhar, ela ainda assim possui uma loucura, a que é incitada por causas políticas ou religiosas, ou por ambas combinadas." (from "O mundo assombrado pelos demônios: A ciência vista como uma vela no escuro" by Carl Sagan, Charles Mackay)”
