Experimental philosophy is one of the most exciting and controversial philosophical movements today. This book explores how it is reshaping thought about philosophical method. Experimental philosophy imports experimental methods and findings from psychology into philosophy. These fresh resources can be used to develop and defend both armchair methods and naturalist approaches, on an empirical basis. This outstanding collection brings together leading proponents of this new meta-philosophical naturalism, from within and beyond experimental philosophy. They explore how the empirical study of philosophically relevant intuition and cognition transforms traditional philosophical approaches and facilitates fresh ones. Part One examines important uses of traditional "armchair" methods which are not threatened by experimental work and develops empirically informed accounts of such methods that can potentially stand up to experimental scrutiny. Part Two analyses different uses and rationales of experimental methods in several areas of philosophy and addresses the key methodological challenges to experimental philosophy: Do its experiments target the intuitions that matter in philosophy? And how can they support conclusions about the rights and wrongs of philosophical views? Essential reading for students of experimental philosophy and metaphilosophy, Experimental Philosophy, Rationalism, and Naturalism will also interest students and researchers in related areas such as epistemology and the philosophies of language, perception, mind and action, science and psychology.
