Abstract

In his book Scientific Realism and the Plasticity of Mind, Paul Churchland suggests that the singular terms for prepositional attitude predicates serve an adverbial function as elements of complex predicates. This view, called monadic adverbialism, has three problems. First the monadic predicates cannot be semantic primitives because this would compromise the learnability of the language containing them. Second, the account has no way to analyze general de dicto beliefs that does not compromise the language being learnable. Third, the account requires that de re behefs be treated as instances of general de dicto beliefs, which leads back to the second problem. The conclusion is that monadic adverbialism ought to be rejected.
