It is a widely held view in philosophy that propositions perform a plethora of different theoretical roles. Amongst other things, they are believed to be the semantic values of sentences in contexts, the objects of attitudes, the contents of illocutionary acts, and the referents of that-clauses. This assumption is often combined with the claim that propositions have their truth-values eternally. In this paper I aim to show that these two assumptions are incompatible: propositions cannot both fulfill the mentioned roles and (...) be eternally true or false. Following Kaplan and Lewis’s Operator Argument, I argue that compositional semantic values of sentences in contexts do not correspond to eternal propositions. Thus, either we regard the non-eternal entities that in fact realize the semantic role of propositions as also fulfilling the remaining propositional roles, or we abandon the assumption that there is a unique realizer of all the roles. The Operator Argument has recently come under attack, mainly for its tense-logical assumptions. However, rejecting these assumptions is not a sufficient defense of the compatibility of the two claims, since the extensional alternative to the tense-logical framework does not allow us to universally retain eternal propositions as compositional semantic values of sentences either.

The main aim of the thesis is to give a semantic account of implicit content – the kind of content that plays a crucial role in implicit communication. Implicit communication is a species of communication in which a speaker communicates certain contents that go over and above the contents retrievable from the linguistic meaning of the words used. The focus of the thesis is a certain kind of implicit communication involving locations (when sentences such as “It is raining” are used (...) to communicate that it is raining at a certain location) and judges (when sentences such as “Avocado is tasty” are used to communicate that avocado is tasty for a certain person, called “the judge”). The way the topic of implicit content is approached is via the notion, widespread in contemporary philosophy of language, of “unarticulated constituents”. The thesis contains an investigation of this notion, with the specific aim of disentangling the many senses it has been used and of providing a general definition of the notion. A direct product of this investigation is a partitioning of the logical space; three positions are then selected, which correspond to the main contenders in the current debate involving unarticulated constituents: truth-conditional semantics, truth-conditional pragmatics and relativism. The biggest part of the thesis is dedicated to investigating certain arguments that have surfaced in the debate between these positions, with the ultimate goal of proposing a relativist account of implicit content. The particular version of relativism offered consists in the combination of the claim that locations and judges are part of the circumstances of evaluation, rather than the content of utterances, with “the variadic functions approach” to certain natural language expressions. Also, several arguments against a truth-conditional semantic approach to predicates of personal taste are provided. (shrink)
