Jeffrey Bell offers a novel approach to thinking about a number of longstanding problems in metaphysics, issues that have persisted throughout the history of philosophy. By developing a metaphysics of problems, he shows how the history of both the analytic and continental traditions of philosophy can be seen to be an ongoing response to the problem of regresses. By highlighting this shared history, Bell brings these two traditions back together to address problems that have been essential to their projects all along and central to much of the history of philosophy.
