Coleridge and the Crisis of Reason examines Coleridge's understanding of the pantheism controversy - the crisis of reason in German philosophy - revealing the context informing Coleridge's understanding of German thinkers. It challenges previous accounts of the poet's philosophical engagements, forcing a reconsideration of his understanding of figures such as Schelling, Jacobi and Spinoza. The argument is built on original research into Coleridge's MS materials, marginal annotations and even plagiarisms from these figures, to provide a close textual analysis of his understanding of them. Most importantly, this exciting new study establishes the central importance of the contested status of reason for Coleridge's poetry, accounts of the imagination and later religious thought, revealing his fundamental anxiety over the status of the rational subject.
