Shifting Concepts

Abstract

Abstract Concepts stand at the centre of human cognition. We use concepts in categorizing objects and events in the world, in reasoning and action, and in social interaction. It is therefore not surprising that the study of concepts constitutes a central area of research in philosophy and psychology. Since the 1970s, psychologists have carried out intriguing experiments testing the role of concepts in categorizing and reasoning, and have found a great deal of variation in categorization behaviour across individuals and cultures. During the same period, philosophers of language and mind did important work on the semantic properties of concepts, and on how concepts are related to linguistic meaning and linguistic communication. An important motivation behind this was the idea that concepts must be shared, across individuals and cultures. However, there was little interaction between these two research programs until recently. With the dawn of experimental philosophy, the proposal that the experimental data from psychology lacks relevance to semantics is increasingly difficult to defend. Moreover, in the last decade, philosophers have approached questions about the tension between conceptual variation and shared concepts in communication from a new perspective: that of ameliorating concepts for theoretical or for social and political purposes. The volume brings together leading psychologists and philosophers working on concepts who come from these different research traditions.
