I argue that conventional implicatures embed in logical compounds, and are non-truth-conditional contributors to sentence meaning. This, I argue has significant implications for how we understand truth, truth-conditional content, and truth-bearers.

The paper contains a critical analysis of pluripropositionalism (or: multiple proposition approach), the view defended in recent years by authors such as Eros Corazza, Kepa Korta and John Perry.

In this paper, I will explore a notion of a truth-bearing entity that is distinct both from a proposition and from an intentional event, state, or action, and that is the notion of an attitudinal object. Attitudinal objects are entities like ‘John’s belief that S’, John’s claim that S’, ‘John’s desire that S’, or ‘John’s request that S’. The notion of an attitudinal object has an important precedent in the work of the Polish philosopher Twardowski (1912), who drew a more (...) general distinction between ‘actions’ and ‘products’, such as walking, screaming, judging, and thinking on the one hand and a walk, a scream, a judgment, and a thought on the other hand. While Twardowski left the distinction at an intuitive level, I will propose an ontological account of the distinction, based on the notion of a trope or particularized property. (shrink)

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.
