 As we’ve seen, much work in experimental philosophy presupposes that intuitions play an important role in philosophical inquiry. Work in the negative program characteristically starts with the assumption that intuitions play a central role in the philosophical tradition. Outside of the negative program, experimental philosophers want to understand what people’s intuitions are about philosophical matters and why they have these intuitions. Several philosophers, however, challenge the role of intuitions in philosophy in ways that also pose a challenge to the philosophical significance of much experimental philosophy.
