Extraordinary Popular Delusions & the Madness of Crowds

by Charles Mackay

It was once thought a venial offence in very many countries of Europe to destroy an enemy by slow poison. Persons who would have revolted at the idea of stabbing a man to the heart, drugged his pottage without scruple. Ladies of gentle birth and manners caught the contagion of murder, until poisoning, under their auspices, became quite fashionable.

Men, it has been well said, think in herds; it will be seen that they go mad in herds, while they only recover their senses slowly, and one by one.

Great saints, great sinners; great philosophers, great quacks; great conquerors, great murderers; great ministers, great thieves; each and all have had their admirers, ready to ransack earth, from the equator to either pole, to find a relic of them.

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 greatest in times of calamity. Prophecies of all sorts are rife on such occasions, and are readily believed, whether for good or evil. During the great plague, which ravaged all Europe, between the years 1345 and 1350, it was generally considered that the end of the world was at hand. Pretended prophets were to be found in all the principal cities of Germany, France, and Italy, predicting that within ten years the trump of the Archangel would sound, and the Saviour appear in the clouds to call the earth to judgment.

The number of persons who confessed that they were employed by the Devil to distribute poison is almost incredible. An epidemic frenzy was abroad, which seemed to be as contagious as the plague. Imagination was as disordered as the body, and day after day persons came voluntarily forward to accuse themselves. They generally had the marks of disease upon them, and some died in the act of confession.

It was not death that a duellist feared: it was shame, and the contempt of his fellows.

in Germany, it was held highly disgraceful to refuse to fight. Any one who surrendered to his adversary for a simple wound that did not disable him, was reputed infamous, and could neither cut his beard, bear arms, mount on horseback, or hold any Office in the state. He who fell in a duel was buried with great pomp and splendour.

We all pay an involuntary homage to antiquity – a “blind homage,” as Bacon calls it in his “Novum Organum,” which tends greatly to the obstruction of truth. To the great majority of mortal eyes, Time sanctifies everything that he does not destroy. The mere fact of anything being spared by the great foe makes it a favourite with us, who are sure to fall his victims.
