Recent philosophy has seen the idea of the transcendental, first introduced in its modern form in the work of Kant, take on a new prominence. Bringing together an international range of younger philosophers and established thinkers, this volume opens up the idea of the transcendental, examining it not merely as a mode of argument, but as naming a particular problematic and a philosophical style. From contemporary rethinkings of the Kantian project through to the holistic, externalist inquiries of Donald Davidson, transcendental styles of reasoning and the broader framework of transcendental inquiry have come to play an important role in the work of a number of philosophers. Beginning with Kant, the contributions in this volume explore the idea of the transcendental in its original historical context, as well as its more recent appearance in relation to Heidegger, Husserl, Apel, Derrida, Chomsky, McDowell, and Davidson. As well as providing insight into the idea of the transcendental, the book also offers new approaches to the work of many of these thinkers. With contributions engaging with both analytic and continental approaches, this book will be of essential interest to philosophers and philosophy students interested in the idea of the transcendental and the part that it plays in modern and contemporary philosophy.
