15. Though the bibliographers claim to have traced the authorship in most cases, such works were in the first instance generally published anonymously, [1038] as were those of Voltaire, d'Holbach, and the leading freethinkers; and the clerical policy of suppression had the result of leaving them generally unanswered, save in anonymous writings, when they nevertheless got into private circulation. It was generally impolitic that an official answer should appear to a book which was officially held not to exist; so that the orthodox defence was long confined mainly to the classic performances of Pascal, Bossuet, Huet, Fénelon, and some outsiders such as the Protestant Abbadie, who settled first in Berlin and later in London. The polemic of every one of the writers named is a work of ability; even that of Abbadie (Traité de la Vérité de la religion chrétienne, 1684), though now little known, was in its day much esteemed. [1039] In the age of Louis XIV those classic answers to unbelief were by believers held to be conclusive; and thus far the French defence was certainly more thorough and philosophical than the English. But French freethought, which in Herbert's day had given the lead to English, now drew new energy from the English growth; and the general arguments of the old apologists did not explicitly meet the new attack. Their books having been written to meet the mostly unpublished objections of previous generations, the Church through its chosen policy had the air of utter inability to confute the newer propaganda, though some apologetic treatises of fair power did appear, in particular those of the Abbé Bergier. [1040] By the avowal of a Christian historian, "So low had the talents of the once illustrious Church of France fallen that in the latter part of the eighteenth century, when Christianity itself was assailed, not one champion of note appeared in its ranks; and when the convocation of the clergy, in 1770, published their famous anathema against the dangers of unbelief, and offered rewards for the best essays in defence of the Christian faith, the productions called forth were so despicable that they sensibly injured the cause of religion."
