Jeffrey Bell argues that a motivating problematic for existentialist writers is the attempt to think through the implications of the problematic nature of life. He applies a Deleuzian theory of problems to an analysis of some key concepts in contemporary social and political theory. Building on the metaphysics of problems set out in his book, An Inquiry into Analytic-Continental Metaphysics, he provides a new way of integrating the concerns of existentialist writers into contemporary political and social debates
