During seasons of great pestilence men have often believed the prophecies of crazed fanatics, that the end of the world was come. Credulity is always… - Charles Mackay

Three causes especially have excited the discontent of mankind; and, by impelling us to seek remedies for the irremediable, have bewildered us in a maze of madness and error. These are death, toil, and the ignorance of the future..

Let us not, in the pride of our superior knowledge, turn with contempt from the follies of our predecessors. The study of the errors into which great minds have fallen in the pursuit of truth can never be uninstructive. As the man looks back to the days of his childhood and his youth, and recalls to his mind the strange notions and false opinions that swayed his actions at the time, that he may wonder at them; so should society, for its edification, look back to the opinions which governed ages that fled.

Much 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.
