Cheap Propositions

To avoid problems with classical theories that take our mental states to represent in virtue of what propositions they represent, and more recent theories that reverse the representational priority, Grzankowski and Buchanan (Philos Stud 176:3159–3178, 2019) propose a “cheap” theory of propositions that does not assume that they are representational entities. They believe that everything there is to know about propositions is provided by the principle that token mental states have the same propositional content if they represent the same things in the same way. I show that the postulated correlation of propositions with mental states does not suffice for propositions to have standard properties like truth values or constituent structures, or to secure the truth of their other basic principle “essentiality of content.” Their theory tells us so little about what propositions are that there is no reason to believe that propositions are object of mental states, or that they exist at all.
