This book offers translations of early critical reactions to Kant's account of free will. Spanning the years 1784-1800, the translations make available, for the first time in English, works by little-known thinkers including Pistorius, Ulrich, Heydenreich, Creuzer and others, as well as familiar figures including Reinhold, Fichte and Schelling. Together they are a testimony to the intense debates surrounding the reception of Kant's account of free will in the 1780s and 1790s, and throw into relief the controversies concerning the coherence of Kant's concept of transcendental freedom, the possibility of reconciling freedom with determinism, the relation between free will and moral imputation, and other arguments central to Kant's view. The volume also includes a helpful introduction, a glossary of key terms and biographical details of the critics, and will provide a valuable foundation for further research on free will in post-Kantian philosophy.
