This short paper follows up on the exchange between Ray Buchanan and Wayne Davis concerning the theory of speaker meaning put forward by Davis in previous work. I briefly present Davis' main tenets, Buchanan's objections, Davis' replies, and then offer a new case that enforces the problem raised by Buchanan to Davis' theory for speaker meaning.

In performing an act of assertion we are sometimes responsible for more than the content of the literal meaning of the words we have used, sometimes less. A recently popular research program seeks to explain certain of the commitments we make in speech in terms of responsiveness to the conversational subject matter. We raise some issues for this view with the aim of providing a more general account of linguistic commitment: one that is grounded in a more general action‐theoretic notion (...) of responsibility.

The principle of universal instantiation plays a pivotal role both in the derivation of intensional paradoxes such as Prior’s paradox and Kaplan’s paradox and the debate between necessitism and contingentism. We outline a distinctively free logical approach to the intensional paradoxes and note how the free logical outlook allows one to distinguish two different, though allied themes in higher-order necessitism. We examine the costs of this solution and compare it with the more familiar ramificationist approaches to higher-order logic. Our assessment (...) of both approaches is largely pessimistic, and we remain reluctantly inclined to take Prior’s and Kaplan’s derivations at face value. (shrink)
