An extraordinary book. Not only does it equal, if not surpass, all previous philosophical dictionaries in the amount and breadth of the material covered, it is full of the life of contemporary issues. Abbagnano is a master of economic expositions, and a careful organizer and editor. Four unique features deserve notice; the historical background of terms is given fully, with detailed bibliography; non technical terms are included, e.g., names of schools, with historical reports; American thought is represented to a degree far beyond that of any other European dictionary; Abbagnano has taken a very comprehensive view of philosophy; which takes in the social sciences as well as the entire spectrum of the usual academics classifications. And finally, the book is a pleasure to read, being gracefully written and free of encumbrances and short cuts, common to most dictionaries.
