Abstract

A strong impossibility is a situation that is epistemically, but not metaphysically, possible. Opponents of strong impossibilities (including Chalmers, Jackson and Stalnaker) have argued that we have “overwhelming reason” to reject and “very little” or “no reason” to think that such impossibilities exist. This partial draft argues that there are strong impossibilities and (very briefly) discusses the manner in which the existence of strong impossibilities is related to some much-discussed arguments in the philosophy of conscious experience. (The full version of the paper will ultimately include a reply to the most significant argument against strong impossibilities, and a (slightly) more involved discussion of the relevance of all of this to issues in the philosophy of conscious experience.).
