This volume of Philosophical Issues, on normativity, has unusually broad scope, and should have correspondingly broad appeal both because of its issues and because of its contributors. The volume includes contributions to moral psychology, theory of reasons and rationality, political philosophy, ethics, metaethics, and epistemology. Its authors, who include both established philosophers whose published work has already attained distinction, and those who are emerging for their recent contributions, are as follows; Nomy Arpaly, Robert N. Audi, Paul Boghossian, John Broome, Thomas L. Carson, Justin D'Arms, David Estlund, Fred Feldman, Bernard Gert, Allan Gibbard, Mark Greenberg, Gilbert Harman, Thomas E. Hill, Jr. , Paul Horwich, Frank Jackson, Jefferson McMahan, Russ Shafer-Landau, Walter Sinnott-Armstrong, Michael Slote, Larry Temkin, Mark Timmons. The volume will also feature a book symposium on Brad Hooker's Ideal Code, Real World, with contributions by Richard Arneson and Alison McIntyre, along with Brad Hooker's response.
