First published in 2001. Willard Van Orman Quine (1908- ) has played a crucial role in philosophy during the second half of the 20th century. Early encyclopedias classified him as a logician, but he soon came to be regarded as a general philosopher, to begin with as a philosopher of logic and language, but eventually as a metaphysician, whose radical thoughts about ontology, epistemology and communication have repercussions within all major areas of philosophy. This series includes a selection of essays from his five volumes of work.
