Every psychiatrist knows the insane whose delirium is combined with religious or mystic exaltation, and who by the mysticism of their delirium have exercised and continue to exercise a profound influence on the mass of humanity which surround them—"Panurge's Sheep," if I may use the expression. These people are themselves so dominated by the pathological influence of their auto-suggestions or their delirium that they behave with the fanaticism of fakirs, and exhibit an extraordinary energy and perseverance in the pursuit of the object of their morbid ideas. By their assurance, the sentiment of infallibility, and the fire of faith which is manifested in their prophetical manner, they fascinate the feeble brains of the people who surround them and attract them by their suggestive action.

A very human and often powerful eroticism is usually associated with their delirium; but it is covered by a cloak of religious ecstasy, which imposes on natures disposed to exaltation, and renders them blind to the ignominy which often lies under this ecstasy.

What makes these patients so persuasive is the fact that they are themselves persuaded. Even the normal man, we must admit, is guided less by reason than by sentiment, and the persons we have just described exert a powerful action on sentiment, and this more by their piercing glance, their prophetic and dominating tone, their manner and appearance, than by the extremely confused text of their discourses and doctrines.

In this way there are always arising small epidemics of attraction in which a group of individuals allows itself to be infatuated by so-called prophets, messiahs, holy virgins and other visionaries, who are only lunatics or crazy persons. Under their influence are produced certain forms of insanity by contagion, which have been called double, triple or quadruple madness, and which may sometimes take the form of an epidemic.

When the "prophet" is more consistent in his words and actions, or when his environment is still very ignorant and superstitious, the crowd of believers increases still more rapidly, and thus one sees even at the present day in less-civilized countries new sects or religious guilds, more or less ephemeral, in which the spirit of the prophet sometimes stirs up grave sexual orgies.

Among more cultured people the prophet is generally exposed or sent to a lunatic asylum, much to the indignation of his disciples, who often consist of his wife and children and a few feeble-minded acquaintances.

Thanks to the cheapness of printing, these prophets often publish their new religious system and sell it among their dupes. I possess a small library of works of this kind which have been sent me by their authors; probably with the idea that they might one day be taken for fools, and to prove to me in advance that they were not.

According to them, God has personally revealed to them the new truth in which they believe, and has appointed them as prophets. Erotic images are generally associated with their system. One of them, whose system is astronomical, divides the planets into males and females. Another, a lunatic, describes the pathological sexual sensations by the term of "psycho-sexual contact by action at a distance." These are phenomena which we meet with at each step in psychiatry, and which give the clue to what follows.

The Historical Role of Mental Anomalies which are Not Very Apparent and Border on Genius. Their Influence on Religious Eroticism.—These persons are not always afflicted with paranoia or other grave psychoses, but often hereditary and constitutional psychopaths who are only half-crazy or simply hysterical, and who may, in spite of this defect, possess a certain degree of intellectual power, an energetic will and the fire of enthusiasm. Things then take an essentially different course, even when they rest on an analogous basis.

The prophet combines with his exaltation a logic which is often very concise in its details, although applied on a morbid basis. Moreover, he clothes his utterances in fine and poetical language, and in this way succeeds in rallying round him, not a flock of Panurge's ignorant sheep, but more elevated people and even a considerable proportion of the surrounding society. In this case pathological exaltation may be united to a high moral and intellectual ideal, which is very apt to veil the bizarre fancies of the prophet. We thus meet with the astonishing but undeniable fact that certain great historical personalities who have exercised a powerful influence on humanity were of more or less pathological nature. We discover among them erotico-religious traits, more or less marked, often even as the leading threads of their arguments.
