This chapter explores the extensive discussion of the sublime in eighteenth-century English, Irish and Scottish philosophy, often considered as laying the groundwork for the Romantic sublime. The chapter also examines academic histories of these eighteenth-century discussions of the sublime, showing how such histories have at times over-simplified the relationship between competing philosophical approaches and national traditions. The chapter pays particular attention to the increasing centrality of the association of ideas to descriptions of the sublime in Anglophone philosophy, identifying it as a key marker of difference from the German idealist tradition that has been the focus of so many scholarly accounts of the Romantic sublime.
