This multidisciplinary edited book presents a different and new perspective from the recent work of Oslington et al., which seeks to reduce the political economy of eighteenth- and nineteenth-century Britain to religiosity and theology, triggered by the writings of A. M. C. Waterman. Unlike those works, the present one aims to re-examine the largely forgotten Butler, who was said in the nineteenth century to be the most influential cleric and preacher in the Church of England of the previous century— not just as a clerical ideologue, but mainly as a proto-political economistbefore Adam Smith. In order to achieve this goal, first, the authors clarify that Butler's theory of conscience and probability, which began with passion and selfishness, was created with the development of eighteenth-century commercial society in mind. Second, the manner in which Butler's discourse was directed not at anti-Anglicans or eminent intellectuals, but at the majority of ordinary secular society, is explored. How it was consistent with and defended their sentiments and economic behavior, not only in Analogy but mainly in Fifteen Sermons, is also investigated and explained. Finally, readers see that Butler's antirational grasp of humanity and empiricist epistemology, based on “probability” presented in these inquiries, can in fact be considered a pioneering expression of the methodological premises of modern economics.
