Theory Selection in Modal Epistemology
by Robert William Fischer
Accounts of modal knowledge are many and varied. How should we choose between them? I propose
that we employ inference to the best explanation, and I suggest that there are three desiderata that we
should use to rank hypotheses: conservatism, simplicity, and the ability to handle disagreement. After
examining these desiderata, I contend that they can't be used to justify belief in the modal epistemology
that fares best, but that they can justify our accepting it in an epistemically significant sense.
Finally, I outline a modal epistemology that seems to do well by the standards I've recommended.
