The author was at the acmé of his wishes. After having pompously announced that the seat of the soul is in the meninges (cerebral membrane), could there be any thing to fear from the liberal thinker of Ferney? He had only forgotten that the patriarch was above all a man of good taste, and that the book on the body and soul offended all the proprieties of life. Voltaire's article appeared. He began with this severe and just lesson—"We should not be prodigal of contempt towards others, and of esteem for ourselves, to such a degree as will be revolting to our readers." The end was still more overwhelming. "We see harlequin everywhere cutting capers to amuse the pit."
Harlequin had received a sufficient dose. Not having succeeded in literature, he threw himself upon the sciences.
On betaking himself to this new career, the doctor of Neufchatel attacked Newton. But unluckily his criticisms were directed precisely to those points wherein optics may vie in evidence with geometry itself. This time the patron was M. de Maillebois, and the tribunal the Academy of Sciences.
The Academy pronounced its judgment gravely, without inflicting a word of ridicule; for example, it did not speak of harlequin; but it did not therefore remain the less established that the pretended experiments, intended, it was said, to upset Newton's, on the unequal refrangibility of variously coloured rays, and the explanation of the rainbow, &c., had absolutely no scientific value.
Still the author would not allow himself to have been beaten. He even conceived the possibility of retaliation; and, availing himself of his intimacy with the Duke de Villeroy, governor of the second city in the kingdom, he got the Academy of Lyons to propose for competition all the questions in optics, which for several years past had been the subjects of its disquisitions; he even furnished the amount of the prize out of his own pocket, under an assumed name.
The prize so longed for, and so singularly proposed, was not obtained, however, by the Duke de Villeroy's candidate, but by the astronomer Flaugergues. From that instant, the pseudo-physicist became the bitter enemy of the scientific bodies of the whole universe, of whoever bore the title of an academician. Putting aside all shame, he no longer made himself known in the field of natural philosophy, merely by imaginary experiments, or by juggleries; he had recourse to contemptible practices, with the object of throwing doubt upon the clearest and best proved principles of science; for example, the metallic needles discovered by the academician Charles, and which the foreign doctor had adroitly concealed in a cake of resin, in order to contradict the common opinion of the electric non-conductibility of that substance.
These details were necessary. I could not avoid characterizing the journalist who by his daily calumnies contributed most to undermine the popularity of Bailly. It was requisite besides, once for all, to strip him in this circle of the epithet of philosopher, with which men of the world, and even some historians, inconsiderately gratified him. When a man reveals himself by some brilliant and intelligent works, the public is pleased to find them united with good qualities of the heart. Nor should its joy be less hearty on discovering the absence of all intellectual merit in a man who had before shown himself despicable by his passions, or his vices, or even only by serious blemishes of character.
If I have not yet named the enemy of our colleague, if I have contented myself with recounting his actions, it is in order to avoid as much as I can the painful feeling that his name must raise here. Judge, Gentlemen, weigh, my scruples: the furious persecutor of Bailly, of whom I have been talking to you for some minutes, was Marat.
The revolution of '89 just occurred in time to relieve the abortive author, physiologist, and physicist from the intolerable position into which he had been thrown by his inability and his quackery.
As soon as the revolution had assumed a decided movement, great surprise was occasioned by the sudden transformations excited in the inferior walks of the political world. Marat was one of the most striking examples of these hasty changes of principles. The Neufchatel physician had shown himself a violent adversary to those opinions that occasioned the convocation of the assembly of Notables, and the national commotion in '89. At that time democratical institutions had not a more bitter or more violent censor. Marat liked it to be believed that in quitting France for England, he fled especially from the spectacle of social renovation which was odious to him. Yet a month after the taking of the Bastille, he returned to Paris, established a journal, and from its very beginning left far behind him, even those who, in the hope of making themselves remarkable, thought they must push exaggeration to its very farthest limits. The former connection of Marat with M. de Calonne was perfectly well known; they remembered these words of Pitt's: "The French must go through liberty, and then be brought back to their old government by licence;" the avowed adversaries of revolution testified by their conduct, by their votes, and even by their imprudent words, that according to them, the worst was the only means of returning to what they call the good; and yet these instructive comparisons struck only eight or ten members of our great assemblies, so small a share has suspicion in the national character, so painful is distrust to French sincerity. The historians of our troubles themselves have but skimmed the question that I have just raised—assuredly a very important and very curious one. In such matters, the part of a prophet is tolerably hazardous; yet I do not hesitate to predict, that a minute study of the conduct and of the discourses of Marat, would lead the mind more and more to those chapters in a treatise on the chase, wherein we see depicted bad species of falcons and hawks, at first only pursuing the game by a sign from the master, and for his advantage; but by degrees taking pleasure in these bloody struggles, and entering on the sport at last with passion and for their own profit.
