This book is the first complete survey and critical appraisal of the large body of research that has appeared during approximately the last decade concerning the analysis of knowing. Robert K. Shope pays special attention to the social aspects of knowing and proposes a new formulation of the fundamental structure of the Gettier problem. Originally published in 1983. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.
