In studying Kant's account of reason, the author of this text argues that his philosophy reconceives the nature of reason and provides a basis for the unity of theory and practice. The role of reason in Kant's accounts of science, morality, religion and philosophy is explored from this perspective.

"This book constitutes a masterful rereading of Kant....Neiman not only covers ground rarely covered by commentators but also shows how this neglect leads them to misinterpretation....Neiman's study...is by far the most careful analysis of this difficult area of Kant's work. The clarity of her thinking and the lucidity of her writing make this book a major achievement."--Ethics "Approaching Kant's critical philosophy from the point of view of his novel, and indeed revolutionary conception of reason sheds striking new light on this philosophy--and, in particular, on Kant's overriding emphasis on the unity of theoretical and practical reason. The Unity of Reason is the best extended treatment of Kant's conception of reason yet to appear."--Michael Friedman, University of Illinois at Chicago "In the case it makes for the necessity of Ideas in science, The Unity of Reason is an important contribution both to Kant scholarship and to contemporary philosophic concerns."--Mary Gregor, San Diego State University "This book offers a unified interpretation of reason in Kant's critical philosophy--one which places at center stage Kant's political commitment to human rights. I found the book at once deep, clear, and thrilling."--Jonathan Lear, author of Love and Its Place in Nature "This essay proposes a very important general account of Kant's critical philosophy....Neiman goes further than previous writers in elaborating the critical definition of "reason."....With its powerful challenge--both the philosophical and exegetical--to the epistemologically-focused mainstream of Kant-scholarship, this book will deservedly be central to future discussion of the meaning and intent of the critical enterprise."--Review of Metaphysics "This book constitutes a masterful rereading of Kant....Neiman not only covers ground rarely covered by commentators but also shows how this neglect leads them to misinterpretation....Neiman's study...is by far the most careful analysis of this difficult area of Kant's work. The clarity of her thinking and the lucidity of her writing make this book a major achieve ment."--Ethics
