The book is a tour de force. In ten closely argued chapters that display both philosophical acumen and a consummate grasp of a wide range of Kant's texts and their historical context, Nicholas Stang shows how a set of interconnected issues in modal metaphysics play an absolutely central role in Kant's pre-Critical philosophy, in motivating the Critical turn, and finally in the Critical philosophy itself. The resulting narrative is rich in insight and compelling ... This is a book of impressive scope, made all the more impressive by the fact that it thereby sacrifices nothing in quality.

Nick Stang offers an extremely meticulous and original study of Immanuel Kant's theory of modality. It is the first book dedicated solely to Kantian modality in the Anglophone Kant literature, crowning the recent surge of articles on the subject, while also setting up a fertile ground for further discussion. The book's appeal is not limited to Kant readers. Considering its historical focus and scope, Stang's book is unusually rigorous, analytically argued, and well informed by twentieth-century modal metaphysics and logic, making it perfectly accessible to those who are interested in modality from a contemporary metaphysical point of view.

Kant's Modal Metaphysics charts a fascinating course from Kant's pre-Critical ideas about modality through to his more mature, Critical, view. We are not just offered an account of what Kant said about some narrow topicmodalitybut rather a narrative according to which questions arising from Kant's modal metaphysics play a crucial role in motivating and shaping the Critical philosophy
