Bourdaloue more than half a century before had taunted the free-thinkers of his day with falseness and inconsistency in taking sides with the Jansenists, whose superstitions they notoriously held in open contempt. The motive for the alliance was tolerably obvious. The Jansenists, apart from their theology, were above all else the representatives of opposition to authority. It was for this that Lewis XIV. counted them worse than atheists. The Jesuits, it has been well said in keeping down their enemies by force, became the partisans of absolute government, and upheld it on every occasion. The Jansenists, after they had been crushed by violence, began to feel to what excesses power might be brought. From being speculative enemies to freedom as a theory, they became, through the education of persecution, the partisans of freedom in practice. The quarrel of Molinists and Jansenists, from a question of theology, grew into a question of human liberty.[131]
Circumstances had now changed. The free-thinkers were becoming strong enough to represent opposition to authority on their own principles and in their own persons. Diderot's vigorous remonstrance with the bishop of Auxerre incidentally marks for us the definite rupture of philosophic sympathy for the Jansenist champions. "It is your disputatiousness," he said, "which within the last forty years has made far more unbelievers than all the productions of philosophy." As we cannot too clearly realise, it was the flagrant social incompetence of the church which brought what they called Philosophy, that is to say Liberalism, into vogue and power. Locke's Essay had been translated in 1700, but it had made no mark, and as late as 1725 the first edition of the translation remained unsold. It was the weakness and unsightly decrepitude of the ecclesiastics which opened the way for the thinkers.
This victory, however, was not yet. Diderot had still a dismal wilderness to traverse. He was not without secret friends even in the camp of his enemies.
After his reply to Peré Berthier's attack on the Prospectus, he received an anonymous letter to the effect that if he wished to avenge himself on the Jesuits, there were both important documents and money at his command. Diderot replied that he was in no want of money, and that he had no time to spare for Jesuit documents.[132] He trusted to reason. Neither reason nor eloquence availed against the credit at court of the ecclesiastical cabal. The sale of the second volume of the Encyclopædia was stopped by orders which Malesherbes was reluctantly compelled to issue. A decree of the king's council (Feb. 7, 1752) suppressed both volumes, as containing maxims hostile to the royal authority and to religion. The publishers were forbidden to reprint them, and the booksellers were forbidden to deliver any copies that might still be in hand. The decree, however, contained no prohibition of the continuance of the work. It was probably not meant to do anything more serious than to pacify the Jesuits, and lend an apparent justification to the officious pastorals of the great prelates. Some even thought that the aim of the government was to forestall severer proceedings on the part of the parliament of lawyers;[133] for corporations of lawyers have seldom been less bigoted or obstructive than corporations of churchmen. Nor were lawyers and priests the only foes. Even the base and despicable jealousies of booksellers counted for something in the storm.[134]
