Experimental Philosophy
Philosophers have argued that some philosophical concepts are universal, but it is increasingly clear that the question of philosophical universals is far from settled, and that far more cross-cultural research is necessary. In this chapter, we illustrate the relevance of investigating philosophical concepts and describe results from recent cross-cultural studies in experimental philosophy. We focus on the concept of knowledge and outline an ongoing project, the Geography of Philosophy Project, which empirically investigates the concepts of knowledge, understanding, and wisdom across cultures, languages, religions, and socioeconomic groups. We outline questions for future research on philosophical concepts across cultures, with an aim towards resolving questions about universals and variation in philosophical concepts.
