Many philosophers believe in things, propositions, which are the things that we believe, assert etc., and which are the contents of sentences. The act-type theory of propositions is an attempt to say what propositions are, to explain how we stand in relations to them, and to explain why they are true or false. The core idea of the act-type theory is that propositions are types of acts of predication. The theory is developed in various ways to offer explanations of the (...) important properties of propositions. I present the core idea of the theory, and some developments of it. I discuss the relationship between the theory and the content–force distinction. I also present an important type of objection that has been raised to the explanations offered by the act-type theory.

In a novel move against Russellianism, Heck (2014) has argued that reports of the form S believes that p are semantically opaque on the grounds that there are no other means in English to report psychologically individuated beliefs, such as those Lois Lane reports using the names ‘Superman’ and ‘Clark Kent.’ I show that there are several other ways to meet this need. I focus on quotational reports of the form S believes “p,” which philosophers have overlooked or mischaracterized. I (...) argue that reports of this form are no more metalinguistic than those using the complementizer that. In both, the meaning of the report depends on the meaning, not the form, of the complement. Some distinguishing features of non-metalinguistic quotational reports are that their complements force “deictic shift” and have no transparent interpretation. Free direct speech and thought bubbles have the same properties. The “q-ascriptions” McCullagh (2017a) proposed to defend Russellianism against Heck are not in common use and on his account are unsuitably metalinguistic. The fact that quotational belief reports are opaque without being metalinguistic makes the Russellian thesis that the meaning of a name is its referent untenable, thereby undermining Russellianism about belief reports.

According to act theories, propositions are structured cognitive act‐types. Act theories appear to make propositions inherently representational and truth‐evaluable, and to provide solutions to familiar problems with alternative theories, including Frege’s and Russell’s problems, and the third‐realm and unity problems. Act theories have critical problems of their own, though: acts as opposed to their objects are not truth evaluable, not structured in the right way, not expressed by sentences, and not the objects of propositional attitudes. I show how identifying propositions (...) with other cognitive event‐types, namely thoughts, has the perceived virtues of act theories without the defects. (shrink)
