Probably the most famous passages in Halévy's work are those attributing England's immunity from revolution after 1789 to the influence of Methodism. The ‘Halévy thesis’ encouraged, though it did not begin, a debate which still fizzes, jumps and occasionally explodes. Little attention has been given to Halévy's first essay in Methodist history, ‘The Birth of Methodism in England’, which appeared in La Révue de Paris in 1906, even though one of its central themes prefigured his famous thesis. After decades of neglect, this has been disinterred, translated and excellently introduced by Bernard Semmel. Compared with Halévy's major writings it is thin and slightly documented, for much of the primary research on which it was based was crowded into a few weeks in the Bodleian Library, after which he seems to have been discouraged by the misleading news that his subject had been pre-empted. The essay remained a rather slender piece, sweepingly written, which found its outlet in a cultural periodical rather than a learned journal. But it is something of a tour de force.
