"This is an excellent volume, in format, in content, and in physical presentation. Förster has provided a very clear, concise, and judicious introduction, which describes the history of Kant's manuscript, its composition, its place in Kant's philosophy, and the development of Kant's views and argument contained in it....The editorial apparatus makes this volume especially useful, and the translators have certainly achieved their aim of making their translation read at least like Kant wherever it cannot quite read like English....Given the intensity of English-language Kant scholarship, this volume does a great service both to Kant and to his students." Kenneth R. Westphal, Review of Metaphysics
