Introduction
There is little question that experimental philosophy constitutes one of the most significant developments in analytic philosophy in the last couple of decades. What is less clear is what its philosophical significance is, or has been. Whereas its proponents tend to present it as a way of moving forward in philosophy, I would argue that its singular contribution thus far has been that of pressing analytic philosophers to reflect on their favored method of inquiry, thereby helping to bring out fundamental problems with that method. More specifically, the present book argues that the new experimental movement and the responses to it by traditional, “armchair” philosophers have helped to make clear that what is known in contemporary analytic philosophy as “the method of cases”—that is, the widespread philosophical practice of theorizing on the basis of the “application” of terms to “cases”—rests on substantive and challengeable assumptions about language.
