Epistemology and Possibility

Recently the discussion surrounding the conceivability thesis has been less about the link between conceivability and possibility per se and more about the requirements of a successful physicalist program. But before entering this debate it is necessary to consider whether conceivability provides us with even prima facie justification for our modal beliefs. I argue that two methods of conceiving—imagining that p and telling a story about p—can provide us with such justification, but only if certain requirements are met. To make these arguments, I consider those of Paul Tidman, whose position I use as a foil.
