A curious triumph awaited the harassed Diderot.
He was compelled, under pain of a second incarceration, to hand over to the authorities all the papers, proof-sheets, and plates in his possession. The Jesuit cabal supposed that if they could obtain the materials for the future volumes, they could easily arrange and manipulate them to suit their own purposes. Their ignorance and presumption were speedily confounded. In taking Diderot's papers, they had forgotten, as Grimm says, to take his head and his genius: they had forgotten to ask him for a key to articles which, so far from understanding, they with some confusion vainly strove even to decipher. The government was obliged (May 1752) to appeal to Diderot and D'Alembert to resume a work for which their enemies had thus proved themselves incompetent. Yet, by one of the meannesses of decaying authority, the decree of three months before was left suspended over their heads.[135]
The third volume of the Encyclopædia appeared in the autumn of 1753. D'Alembert prefixed an introduction, vindicating himself and his colleague with a manliness, a sincerity, a gravity, a fire, that are admirable and touching. "What," he concluded, "can malignity henceforth devise against two men of letters, trained long since by their meditations to fear neither injustice nor poverty; who having learnt by a long and mournful experience, not to despise, but to mistrust and dread men, have the courage to love them, and the prudence to flee them?... After having been the stormy and painful occupation of the most precious years of our life, this work will perhaps be the solace of its close. May it, when both we and our enemies alike have ceased to exist, be a durable monument of the good intention of the one, and the injustice of the other.... Let us remember the fable of Bocalina: 'A traveller was disturbed by the importunate chirrupings of the grasshoppers; he would fain have slain them every one, but only got belated and missed his way; he need only have fared peacefully on his road, and the grasshoppers would have died of themselves before the end of a week.'"[136] A volume was now produced in each year, until the autumn of 1757 and the issue of the seventh volume. This brought the work down to Gyromancy and Gythiuin. Then there arose storms and divisions which marked a memorable epoch alike in the history of the book, in the life of Diderot and others, and in the thought of the century. The progress of the work in popularity during the five years between 1752 and 1757 had been steady and unbroken. The original subscribers were barely two thousand. When the fourth volume appeared, there were three thousand. The seventh volume found nearly a thousand more.[137] Such prodigious success wrought the chagrin of the party of superstition to fever heat. As each annual volume came from the press and found a wider circle of readers than its predecessor, their malice and irritation waxed a degree more intense. They scattered malignant rumours abroad; they showered pamphlets; no imputation was too odious or too ridiculous for them. Diderot, D'Alembert, Voltaire, Rousseau, Buffon, were declared to have organised a league of writers, with the deliberate purpose of attacking the public tranquillity and overthrowing society. They were denounced as heads of a formal conspiracy, a clandestine association, a midnight band, united in a horrible community of pestilent opinions and sombre interests.
