Adapt or Die: The Death of Invariantism?

Contextualists support their view by appeal to cases which show that whether an attribution of knowledge seems correct depends on attributor factors. Contextualists conclude that the truth-conditions of knowledge attributions depend on the attributor's context. Invariantists respond that these cases show only that the warranted assertability-conditions of knowledge attributions depend on the attributor's context. I examine DeRose's recent argument against the possibility of such an invariantist response, an argument which appeals to the knowledge account of assertion and the context-sensitivity of assertion. I argue that DeRose's new argument does not rule out either of the two forms of invariantism, classic and subject-sensitive invariantism. Further, I argue against DeRose that an invariantist can explain the context-sensitivity of assertion.
