DescriptionIn Semantic Quietism, I defend and develop a view according to which only semantic theories that are incomplete in important respects can be compatible with the phenomenon of vagueness. I defend this view by arguing that any semantic theory that attempts to capture every robust semantic fact is incompatible with this phenomenon. Then I show how a semantic theory that is incomplete in the right way can have this kind of compatibility. I call this view Semantic Quietism. Finally, I show how this view can be used to solve some problems had by theories of linguistic communication.
