A timeless classic of economic theory that remains fascinating and pertinent today, this is Frank Knight's famous explanation of why perfect competition cannot eliminate profits, the important differences between "risk" and "uncertainty," and the vital role of the entrepreneur in profitmaking. Based on Knight's PhD dissertation, this 1921 work, balancing theory with fact to come to stunning insights, is a distinct pleasure to read. FRANK H. KNIGHT (1885-1972) is considered by some the greatest American scholar of economics of the 20th century. An economics professor at the University of Chicago from 1927 until 1955, he was one of the founders of the Chicago school of economics, which influenced Milton Friedman and George Stigler.

For thirty years, Peter Singer's Practical Ethics has been the classic introduction to applied ethics. For this third edition, the author has revised and updated all the chapters and added a new chapter addressing climate change, one of the most important ethical challenges of our generation. Some of the questions discussed in this book concern our daily lives. Is it ethical to buy luxuries when others do not have enough to eat? Should we buy meat from intensively reared animals? Am I doing something wrong if my carbon footprint is above the global average? Other questions confront us as concerned citizens: equality and discrimination on the grounds of race or sex; abortion, the use of embryos for research and euthanasia; political violence and terrorism; and the preservation of our planet's environment. This book's lucid style and provocative arguments make it an ideal text for university courses and for anyone willing to think about how she or he ought to live.

Classical Rhetoric in the Middle Ages: The Medieval Rhetors and Their Art 400-1300, with Manuscript Survey to 1500 CE is a completely updated version of John Ward’s much-used doctoral thesis of 1972, and is the definitive treatment of this fundamental aspect of medieval and rhetorical culture. It is commonly believed that medieval writers were interested only in Christian truth, not in Graeco-Roman methods of ‘persuasion’ to whatever viewpoint the speaker / writer wanted. Dr Ward, however, investigates the content of well over one thousand medieval manuscripts and shows that medieval writers were fully conscious of and much dependent upon Graeco-Roman rhetorical methods of persuasion. The volume then demonstrates why and to what purpose this use of classical rhetoric took place.
