In Peru, besides the priests, there were prophets who uttered their improvisations amid terrible contortions and convulsions. They were venerated by the people, but despised by the higher classes.[375]

All revolutions in Algeria and in the Soudan[376] are due to lunatics or neurotics who make, of their own neurosis and the religious societies to which they attach themselves, instruments for invigorating religious fanaticism and getting themselves accepted as inspired messengers of God. Such were the Mahdi, Omar, and a madman who headed the great revolt of the Taepings in China.[377]

Phenomena which present such complete uniformity must arise from like causes. These seem to me to be reducible to the following:

1. The mass of the people, accustomed to the few sensations habitual to them, cannot experience new ones without wonder, or strange ones without adoration. Adoration is, I should say, the necessary effect of the reflex movement produced in them by the overwhelming shock of the new impression. The Peruvians applied the word Huacha (divine) to the sacred victim, the temple, a high tower, a great mountain, a ferocious animal, a man with seven fingers, a shining stone, &c. In the same way the Semitic El (divine) is synonymous with great, light, new, and is applied to a strong man, as well as to a tree, a mountain, or an animal. After all, it is quite natural that men should be struck by the phenomenon of one of their fellow-creatures completely changing his voice and gestures, and associating together the strangest ideas—when we ourselves, with all the advantages of science, are often puzzled to understand the reasons for his actions.

2. Some of these madmen possess (as we have seen, and shall see again, in the Middle Ages and among the Indians) extraordinary muscular strength. The people venerate strength.

3. They often show an extraordinary insensibility to cold, to fire, to wounds (as among the Arab Santons, and among our own lunatics), and to hunger.

4. Some, affected either by theomania or ambitious mania, having first declared themselves inspired by the gods, or chiefs and leaders of the nation, &c., drew after them the current of popular opinion, already disposed in their favour.

5. The following is the principal reason. Many of these madmen must have shown a force of intellect, or at any rate of will, very much superior to those of the masses whom they swayed by their extravagances. If the passions redouble the force of the intellect, certain forms of madness (which are nothing but a morbid exaltation of the passions) may be said to increase it a hundred-fold. Their conviction of the truth of their own hallucinations, the fluent and vigorous eloquence with which they give utterance to them—and which is precisely the effect of their real conviction—and the contrast between their obscure or ignoble past, and their present position of power or splendour, give to this form of insanity, in the mind of the people, a natural preponderance over sane but quiet habits of mind. Lazzaretti, Briand, Loyola, Molinos, Joan of Arc, the Anabaptists, &c., are proofs of this assertion. And it is a fact that, in epidemics of prophecy—such as those which prevailed in the Cevennes, and, recently, at Stockholm—ignorant persons, servant-maids, and even children, excited by enthusiasm, are fired to deliver discourses which are often full of spirit and eloquence.

A maid-servant said, “Can you put a piece of wood in the fire without thinking of hell?—the more wood, the greater the flames.” Another prophetess, a cook, cried out, “God pronounces curses on this wine of wrath (i.e., brandy), and the sinners who drink of it shall be punished according to their sin, and torrents of this wine of wrath shall flow in hell to burn them.” A child of four said, “May God in heaven call sinners to repentance! Go to Golgotha—there are the festal robes!”[378]

6. Mania, among barbarous people, often takes the epidemic form, as among the savage negroes of Juidah, among the Abipones and among the Abyssinians in those affections analogous to the tarantula which are called tigretier. Thus, in Greece, an instance is recorded of an epidemic madness among the people of Abdera, who had been deeply moved by the recital of a tragedy; and those Thyades who appeared at Athens and Rome—worshippers of Bacchus, thirsting for luxury and blood, and seized with sacred fury—were affected by erotico-religious insanity. But this is more especially seen in the Middle Ages, when mental epidemics were continually succeeding one another.
