Memoirs of Extraordinary Popular Delusions and the Madness of Crowds

PREFACE to the first edition

THE OBJECT OF THE AUTHOR in the following pages has been to collect the most remarkable instances of those moral epidemics which have been excited, sometimes by one cause and sometimes by another, and to show how easily the masses have been led astray, and how imitative and gregarious men are, even in their infatuations and crimes.

Some of the subjects introduced may be familiar to the reader; but the Author hopes that sufficient novelty of detail will be found even in these, to render them acceptable, while they could not be wholly omitted in justice to the subject of which it was proposed to treat. The memoirs of the South Sea madness and the Mississippi delusion are more complete and copious than are to be found elsewhere; and the same may be said of the history of the Witch Mania, which contains an account of its terrific progress in Germany, a part of the subject which has been left comparatively untouched by Sir Walter Scott, in his “Letters on Demonology and Witchcraft,” the most important that have yet appeared on this fearful but most interesting subject.

Popular delusions began so early, spread so widely, and have lasted so long, that instead of two or three volumes, fifty would scarcely suffice to detail their history. The present may be considered more of a miscellany of delusions than a history,—a chapter only in the great and awful book of human folly which yet remains to be written, and which Porson once jestingly said he would write in five hundred volumes! Interspersed are sketches of some lighter matters,—amusing instances of the imitativeness and wrongheadedness of the people, rather than examples of folly and delusion.

Religious manias have been purposely excluded as incompatible with the limits prescribed to the present work;—a mere list of them would alone be sufficient to occupy a volume.

In another volume should these be favourably received, the Author will attempt a complete view of the progress of Alchemy and the philosophical delusions that sprang from it, including the Rosicrucians of a bygone, and the Magnetisers of the present, era.

PREFACE to the Edition of 1852

IN 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. We see one nation suddenly seized, from its highest to its lowest members, with a fierce desire of military glory; another as suddenly becoming crazed upon a religious scruple; and neither of them recovering its senses until it has shed rivers of blood and sowed a harvest of groans and tears, to be reaped by its posterity. At an early age in the annals of Europe its population lost their wits about the sepulchre of Jesus, and crowded in frenzied multitudes to the Holy Land; another age went mad for fear of the devil, and offered up hundreds of thousands of victims to the delusion of witchcraft. At another time, the many became crazed on the subject of the philosopher’s stone, and committed follies till then unheard of in the pursuit. 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. Some delusions, though notorious to all the world, have subsisted for ages, flourishing as widely among civilised and polished nations as among the early barbarians with whom they originated,—that of duelling, for instance, and the belief in omens and divination of the future, which seem to defy the progress of knowledge to eradicate them entirely from the popular mind. Money, again, has often been a cause of the delusion of multitudes. Sober nations have all at once become desperate gamblers, and risked almost their existence upon the turn of a piece of paper. To trace the history of the most prominent of these delusions is the object of the present pages. 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.

Some of the subjects introduced may be familiar to the reader; but the Author hopes that sufficient novelty of detail will be found even in these, to render them acceptable, while they could not be wholly omitted in justice to the subject of which it was proposed to treat. The memoirs of the South-Sea madness and the Mississippi delusion are more complete and copious than are to be found elsewhere; and the same may be said of the history of the Witch Mania, which contains an account of its terrific progress in Germany, a part of the subject which has been left comparatively untouched by Sir Walter Scott in his
Letters on Demonology and Witchcraft, the most important that have yet appeared on this fearful but most interesting subject.

Popular delusions began so early, spread so widely, and have lasted so long, that instead of two or three volumes, fifty would scarcely suffice to detail their history.
