Such are the symptoms by which medical men recognize immediately one of those partial lunatics who may not be put in confinement, but who are all the more dangerous;[3119] the malady, as they would express it in technical terms, may be called the ambitious delirium, well known in lunatic asylums.--Two predispositions, one an habitually perverted judgment, and the other a colossal excess of self-esteem,[3120] constitute its sources, and nowhere are both more prolific than in Marat. Never did a man with such diversified culture, possess such an incurably perverted intellect. Never did a man, after so many abortive speculations and such repeated malpractices, conceive and maintain so high an opinion of himself. Each of these two sources in him augments the other: through his faculty of not seeing things as they are, he attributes to himself virtue and genius; satisfied that he possesses genius and virtue, he regards his misdeeds as merits and his whims as truths.--Thenceforth, and spontaneously, his malady runs its own course and becomes complex; to the ambitious delirium comes the persecution mania. In effect, the evident or demonstrated truths which he advances should strike the public at once; if they burn slowly or miss fire, it is owing to their being stamped out by enemies or the envious; manifestly, they have conspired against him, and against him plots have never ceased. First came the philosophers' plot: when his treatise on "Man" was sent to Paris from Amsterdam, "they felt the blow I struck at their principles and had the book stopped at the custom-house."[3121] Next came the plot of the doctors: "they ruefully estimated my enormous gains. Were it necessary, I could prove that they often met together to consider the best way to destroy my reputation." Finally, came the plot of the Academicians; "the disgraceful persecution I had to undergo from the Academy of Sciences for two years, after being satisfied that my discoveries on Light upset all that it had done for a century, and that I was quite indifferent about becoming a member of its body.... Would it be believed that these scientific charlatans succeeded in underrating my discoveries throughout Europe, in exciting every society of savants against me, and in closing against me all the newspapers?"[3122]--Naturally, the would-be-persecuted man defends himself, that is to say, he attacks. Naturally, as he is the aggressor, he is repulsed and put down, and, after creating imaginary enemies, he creates real ones, especially in politics where, on principle, he daily preaches insurrection and murder. And finally, he is of course prosecuted, convicted at the Chatelet court, tracked by the police, obliged to fly and wander from one hiding-place to another; to live like a bat "in a cellar, underground, in a dark dungeon;"[3123] once, says his friend Panis, he passed "six weeks sitting on his behind" like a madman in his cell, face to face with his reveries.--It is not
