Abstract

This is a long paper with a long title, but its moral is succinct. There are supposed to be two, closely related, philosophical problems about sentences1 with truth value gaps: If a sentence can't be semantically evaluated, how can it mean anything at all? and How can classical logic be preserved for a language which contains such sentences? We are neutral on whether either of these supposed problems is real. But we claim that, if either is, supervaluation won't solve it.
