For much of the twentieth century, philosophy and science went their separate ways. In moral philosophy, fear of the so-called naturalistic fallacy kept moral philosophers from incorporating developments in biology and psychology. Since the 1990s, however, many philosophers have drawn on recent advances in cognitive psychology, brain science, and evolutionary psychology to inform their work. This collaborative trend is especially strong in moral philosophy, and these three volumes bring together some of the most innovative work by both philosophers and psychologists in this emerging interdisciplinary field.Contributors to Volume 1:William Casebeer (Air Force Academy), Leda Cosmides (University of California, Santa Barbara), Oliver Curry (London School of Economics), Michael Dietrich (Dartmouth College), Catherine Driscoll (North Carolina State University), Susan Dwyer (University of Maryland, Baltimore County), Owen Flanagan (Duke University), Gilbert Harman (Princeton University), Richard Joyce (Australian National University Research School of Social Science), Debra Lieberman (University of Hawaii), Ron Mallon (University of Utah), John Mikhail (Georgetown Law School), Geoffrey Miller (University of New Mexico), Jesse Prinz (University of North Carolina at Chapel Hill), Peter Railton (University of Michigan), Michael Ruse (Florida State University) Hagop Sarkissian (Duke University), Walter Sinnott-Armstrong (Dartmouth College), Chandra Sekhar Sripada (University of Michigan) Valerie Tiberius (University of Minnesota), John Tooby (University of California, Santa Barbara), Peter Tse (Dartmouth College) Kathleen Wallace (Hofstra University), Arthur Wolf (Stanford University), David Wong (Duke University).
