 “Intuition pumps” or “thought experiments” have long been well-used items in the philosopher’s toolbox (Dennett 1984: 17–18; Stuart et al. 2018). Typically, a thought experiment presents an example, often a hypothetical example, in order to elicit some philosophically telling response. If a thought experiment is successful, it may be concluded that competing theories must account for the resulting response. These responses are supposed to serve an evidential role in philosophical theory choice; if you like, they can be understood as data competing theories must  accommodate.[3]  If an appropriate audience’s ethical responses to a thought experiment conflict with the response a theory prescribes for the case, the theory has suffered a counterexample.
