In seeking to estimate Bolingbroke's posthumous influence we have to remember that after the publication of his works the orthodox members of his own party, who otherwise would have forgiven him all his vices and insincerities, have held him up to hatred. Scott, for instance, founding on Bolingbroke's own dishonest denunciation of freethinkers as men seeking to loosen the bands of society, pronounced his arrangement for the posthumous issue of his works "an act of wickedness more purely diabolical than any hitherto upon record in the history of any age or nation" (Note to Bolingbroke's letter above cited in Swift's Works, xvi, 450). It would be an error, on the other hand, to class him among either the great sociologists or the great philosophers. Mr. Sichel undertakes to show (vol. ii, ch. x) that Bolingbroke had stimulated Gibbon to a considerable extent in his treatment of early Christianity. This is in itself quite probable, and some of the parallels cited are noteworthy; but Mr. Sichel, who always writes as a panegyrist, makes no attempt to trace the common French sources for both. He does show that Voltaire manipulated Bolingbroke's opinions in reproducing them. But he does not critically recognize the incoherence of Bolingbroke's eloquent treatises. Mr. Hassall's summary is nearer the truth; but that in turn does not note how well fitted was Bolingbroke's swift and graceful declamation to do its work with the general public, which (if it accepted him at all) would make small account of self-contradiction.
In view of such a reinforcement of its propaganda, deism could not be regarded as in the least degree written down. In 1765, in fact, we find Diderot recounting, on the authority of d'Holbach, who had just returned from a visit to this country, that "the Christian religion is nearly extinct in England. The deists are innumerable; there are almost no atheists; those who are so conceal it. An atheist and a scoundrel are almost synonymous terms for them." [883] Nor did the output of deistic literature end with the posthumous works of Bolingbroke. These were followed by translations of the new writings of Voltaire, [884] who had assimilated the whole propaganda of English deism, and gave it out anew with a wit and brilliancy hitherto unknown in argumentative and critical literature. The freethinking of the third quarter of the century, though kept secondary to more pressing questions, was thus at least as deeply rooted and as convinced as that of the first quarter; and it was probably not much less common among educated men, though new social influences caused it to be more decried.
