 Related to this is the question of the difference, if any, between thought experiments in the sciences and those in philosophy. We have assumed throughout this article that they are the same kind of thing. Not everyone sees them this way, so perhaps it should be considered an open question. On the one hand, philosophy and science seem to many to be different kinds of activities. That might suggest that thought experiments would differ in the two areas. On the other hand, there is a huge difference between thought experiments within a single field, e.g., Newton’s bucket attempts to establish absolute space while Schrodinger’s cat aims to show QM as then understood to be absurd. Is the difference between them less than the difference between either of them and Searle’s Chinese Room or Thomson’s violinist? The case one way or the other is not obvious. Of course, there are differences between constructive and destructive thought experiments, but this is true within any discipline. Perhaps for now the default attitude ought to be that there is no principle difference between scientific and philosophical thought experiments. This should not be treated as a dogmatic principle, but rather a stimulus to look deeper for important subtle contrasts.
