"With her well-known toughness of mind, Judith Jarvis Thomson develops a systematic account of the entire domain of the normative--moral and non-moral--based upon the idea of being good of a kind. She makes clear just how thoroughly normativity is woven into our daily lives and thoughts, and how wrong it is to think of the normative as mysterious or elusive. Each page brings fresh ideas and arguments. This is a book anyone interested in normativity can read with profit." —Peter Railton, University of Michigan "Normativity is a careful, rigorous account of the meanings of the basic normative terms: good, virtue, correct, ought, should, and must. Along the way, Thomson refutes almost everything other philosophers have said about these topics. It is a very important book." —Gilbert Harman, Princeton University "This much anticipated book intriguingly and surprisingly broadens the scope of the philosophy of normativity. Impressively broad and deeply insightful, it deserves to be widely read and discussed." —Ernest Sosa, Rutgers University
