Contextualism, standard view: The logical form becomes enriched/modulated as a result of pragmatic inference and the entire semantic/pragmatic product becomes subjected to the truth-conditional analysis.
The logical form becomes ?enriched/modulatedas a result of pragmatic inference and the entire semantic/pragmatic product becomes subjected to the truth-conditional analysis.
? How far can the logical form be extended? ‘How much pragmatics’ is allowed in the semantic representation?
The logical form of the sentence can not only be extended but also replaced by a new semantic representation when the primary, intended meaning demands it. Such extensions or substitutions are primary meanings and their representations are merger representations in Default Semantics.There is no syntactic constraint on merger representations.
Outline • Default Semantics • unit of analysis • sources of information contributing to the unit • pragmatic compositionality • merger representations: towards a formalization
Outline • Default Semantics • unit of analysis • sources of information contributing to the unit • pragmatic compositionality • merger representations: towards a formalization • Selected applications: • temporal reference • reports on epistemic attitudes (‘A believes that B s’) • beliefs de se: 1st person reference and ‘cognitive access to oneself’
Radical Contextualism • The output of syntactic processing often leaves the meaning underdetermined.

Interim summary • The output of syntactic processing often leaves the meaning underdetermined. • This pragmatically modified representation is an object of study of a theory of meaning (Default Semantics is a radical contextualist theory). • There is no syntactic constraint on the object of study. • Discourse meaning is construed as meaning intended by the Model Speaker and recovered by Model Addressee.

Interlocutors frequently communicate their main intended content through a proposition which is not syntactically restricted. Experimental evidence: Nicolle and Clark 1999 Pitts 2005 Sysoeva and Jaszczolt 2007
Merger Representation • Primary meanings are modelled as the so-called merger representations.
Merger Representation • Primary meanings are modelled as the so-called merger representations. • The outputs of sources of information about meaning merge and all the outputs are treated on an equal footing.
Merger Representation • Primary meanings are modelled as the so-called merger representations. • The outputs of sources of information about meaning merge and all the outputs are treated on an equal footing. The syntactic constraint is abandoned. • Merger representations have the status of mental representations.

The model of sources of information can be mapped onto types of processes that produce the merger representation of the primary meaning and the additional (secondary) meanings.

Main questions • Is the human concept of time a universal concept? • Is it primitive or composed of simpler concepts? • How do linguistic expressions of time reflect it?

What is expressed in the lexicon in one language may be expressed by grammar in another. What is expressed overtly in onelanguage may be left to pragmatic inference or default interpretation in another.

Merger Representations for the Past (10) Lidia went to a concert yesterday. (regular past) (11)This is what happened yesterday. Lidia goes to a concert, meets her school friend and tells her… (past of narration) (12) Lidia would have gone to a concert (then). (epistemic necessity past) (13) Lidia must have gone to a concert (yesterday). (epistemic necessity past) (14) Lidia may have gone to a concert (yesterday). (epistemic possibility past) (15) Lidia might have gone to a concert (yesterday). (epistemic possibility past)
