I have finished a paper (here) that uses some experimental methods to examine a question that has agitated for a few years the philosophy of concepts: Does the class of concepts fragment into several very heterogeneous kinds?
Here is the abstract:
Psychologists of concepts’ traditional assumption that there are many properties common to all concepts has been subject to devastating critiques in psychology and in the philosophy of psychology. However, it is currently unclear what approach to concepts is best suited to replace this traditional assumption. In this article, we compare two competing approaches, the Heterogeneity Hypothesis and the hybrid theories of concepts, and we present an empirical argument that supports the former over the latter.
Comments are as usual welcome.
(I also note that this paper illustrates that experimental philosophy is not bound to studying people’s intuitive judgments in thought-experiments.)
