In this paper, I will argue for a new account of presuppositions which is based on double indexing as well as minimal representational contexts providing antecedent material for anaphoric presuppositions, rather than notions of context defined in terms of the interlocutors’ pragmatic presuppositions or the information accumulated from the preceding discourse. This account applies in particular to new phenomena concerning the presupposition of quantifier domains. But it is also intended to be an account of presuppositions in general. The account differs from the Satisfaction Theory and the Binding Theory of presuppositions in that it can be viewed as a conservative extension of traditional static semantics and in that it does not involve the notion of pragmatic presupposition.

The aim of natural language ontology is to uncover the ontological categories and structures that are implicit in the use of natural language, that is, that a speaker accepts when using a language. This article aims to clarify what exactly the subject matter of natural language ontology is, what sorts of linguistic data it should take into account, how natural language ontology relates to other branches of metaphysics, in what ways natural language ontology is important, and what may be distinctive of the ontological categories and structures reflected in natural language.

In some recent developments of semantic theory, in particular certain versions of dynamic semantics, ‘internal’ contexts, that is, contexts defined in terms of the interlocutors’ pragmatic presuppositions or the information accumulated in the discourse have come to play a central role, replacing the notion of propositional content in favor of a notion of context change potential as the meaning of sentences. I will argue that there are a number of fundamental problems with this conception of sentence meaning and outline a way of dealing with the ‘dynamic phenomena’ from the perspective of the traditional distinctions between propositional content and (internal) context as well between propositional content and illocutionary force, using structured propositions and minimal discourse-driven internal context.
