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.
Charles MackayIn reading The History of Nations, we find that, like individuals, they have their whims and their peculiarities, their seasons of excitement and recklessness, when they care not what they do. We find that whole communities suddenly fix their minds upon one object and go mad in its pursuit; that millions of people become simultaneously impressed with one delusion, and run after it, till their attention is caught by some new folly more captivating than the first.
Charles MackayMuch as the sage may affect to despise the opinion of the world, there are few who would not rather expose their lives a hundred times than be condemned to live on, in society, but not of it - a by-word of reproach to all who know their history, and a mark for scorn to point his finger at.
