"This original and important book demonstrates the inseparability of philosophy and psychoanalysis for any serious attempt to answer a question so profoundly relevant to the very nature of our being that it does not 'belong' to any one discipline: the question, as Silverman puts it, of what it means for the world that each one of us is in it. The book has a remarkable clarity; Silverman makes the most complex argument seem like a perfectly natural, and absolutely necessary, movement of thought."--Leo Bersani, University of California, Berkeley
