Two systems of presupposition logic.

Presupposition Projection : Two Theories of Local Contexts

The Explanatory Problem discussed in Part I is conceptually simple: dynamic semantics is strictly more powerful than classical semantics; this made it possible for Heim’s system to handle presuppositional data that classical semantics did not; but the very power of the framework also makes it possible to define all sorts of lexical entries which presumably do not exist in the world’s languages....

Two Types of Definites: Evidence for Presupposition Cost

This paper investigates the notion of definiteness from a psycholinguistic perspective and addresses Löbner’s (1987) distinction between semantic and pragmatic definites. To this end inherently definite noun phrases, proper names, and indexicals are investigated as instances of (relatively) rigid designators (i.e. semantic definites) and contrasted with definite noun phrases and third person pr...

Experimental Work in Presupposition and Presupposition Projection

Recent years have seen a surge of experimental approaches to the study of natural language meaning, both to get solid data on subtle phenomena hard to assess through introspection, and to understand how abstract characterizations of linguistic knowledge relate to real-time cognitive processes in language comprehension. The present paper reviews work in one of the most recent areas to see extens...

Presupposition Satisfaction

In this paper the satisfaction approach towards presuppositions is made more compatible with some empirical phenomena by assuming that (i) contexts should contain more information than they are usually said to contain, (ii) that the idea that contexts represent what the speaker is assuming for the sake of conversation should be taken more seriously than is usually done, and (iii) that not all p...
