Abstract
I propose a new theory of semantic presupposition, which I call dissatisfaction
theory. I first briefly review a cluster of problems − known collectively as the
proviso problem − for most extant theories of presupposition, arguing that the main
pragmatic response to them faces a serious challenge. I avoid these problems by
adopting two changes in perspective on presupposition. First, I propose a theory
of projection according to which presuppositions project unless they are locally
entailed. Second, I reject the standard assumption that presuppositions are contents
which must be entailed by the input context; instead, I propose that presuppositions
are contents which are marked as backgrounded. I show that, together, these
commitments allow us to avoid the proviso problem altogether, and generally make
plausible predictions about presupposition projection out of connectives and attitude
predicates. I close by sketching a two-dimensional implementation of my theory
which allows us to make further welcome predictions about attitude predicates and
quantifiers.
