Grue ! : New Riddle Of Induction, The

If every observed emerald is green, and if this supports the conclusion 'All emeralds are green', does it equally support the conclusion 'All emeralds are grue' - where 'grue' is defined as green before a certain date and blue thereafter? Since its publication in 1955, Nelson Goodman's 'Paradox', the new riddle of induction, has emerged as one of the most stimulating philosophical problems of the 20th century. It has exercised some of the best minds of our generation, and drawn a surprising variety of approaches, ranging from artificial intelligence to Bayesianism. This volume contains 14 essays on the grue paradox, seven of them previously published, and seven written specially for this volume. The work includes a detailed history and exposition, and an annotated bibliography of virtually all the literature on the problem to date.
