W.V.O. Quine is one of the most influential of contemporary philosophers, whose work has ranged broadly across a great number of topics and issues in a career spanning some fifty years. In this collection a group of distinguished philosophers offers a sustained critical evaluation of the full range of Quine's writings. Among the topics addressed are interpretation, epistemology, ontology, modality, and mathematical truth. This is very much a "state of the art" collection that will influence all future discussion of Quine.
