This book offers a systematic and detailed examination of the conservative case for religion by establishment. In doing so, the author demonstrates that the conservative political tradition is rooted in an inescapably religious worldview, and in turn shows what the future of conservatism might be. The author begins the book by analysing the thought of prominent proponents of secular conservatism, chiefly examining the work of Roger Scruton. The author develops a case to show that Scruton's arguments on the privatisation of religion are in tension with his basing of a conservative political settlement on "transcendent bonds". The author then examines alternatives to secular conservatism, especially the chief religious and metaphysical commitments of early conservatives, Edmund Burke and Joseph de Maistre. Finally, in seeking to establish a foundational argument for religion by establishment within the conservative tradition, and more broadly to unify the diverse commitments and objections of conservatives, the author develops a case that draws on Scruton's personalism, as well as the thought of Martin Buber, Andrew Pinsent, and Robert Spaemann. In the course of developing his foundational argument, the author incorporates findings from experimental psychology and themes from contemporary theology. The result is a convincing argument in favour of establishmentarian conservatism, as well as the role of religious ideas in our self-understanding as individuals and as a political community. Conservatism and Grace will appeal to scholars and advanced students interested in political philosophy, philosophy of religion, theology, and the history of conservatism.
