Fritz-Gregor (classics and ancient history, Swansea U., Wales) approaches the work of the premier ancient Greek philosopher through particular terms that he uses. He analyzes the various philosophical and literary uses the terms had been put to before Plato, Plato's refinement or alteration of their meanings, and the implications for his work in particular and for the great stream of Western philosophy that flowed from his spring. Quotations are in Greek with English translation. Distributed in North America by The David Brown Book Company. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
