Actuality, indexicality, and knowledge

After summarizing linguistic evidence against the thesis that actuality terms are indexical, I examine conceptual and epistemological arguments offered in favor of an indexical analysis. I argue that an indexical semantics provides no explanation of how we know what is actually the case, and no grounds for postulating a contingent a priori. Truth in every context, or in every model, does not imply knowledge of the fact a sentence expresses nor how we know it if we do. Moreover, descriptive analyses also predict that ‘I exist in the actual world’ and instances of ‘p ≡ Actually p’ are true in every context.
