Kant announces that the Critique of the Power of Judgment will bring his entire critical enterprise to an end. But it is by no means agreed upon that it in fact does so and, if it does, how. In this book, Ido Geiger argues that a principal concern of the third Critique is completing the account of the transcendental conditions of empirical experience and knowledge. This includes both Kant's analysis of natural beauty and his discussion of teleological judgments of organisms and of nature generally. Geiger's original reading of  the third Critique shows that it forms a unified whole - and that it does in fact deliver the final part of Kant's transcendental undertaking. His book will be valuable to all who are interested in Kant's theory of the aesthetic and conceptual purposiveness of nature.
