This paper brings together two positions that for the most part have been developed and defended independently of one another: contextualism about knowledge attributions and the knowledge account of assertion.

This paper uses the knowledge account of assertion (KAA) in defense of epistemological contextualism. Part 1 explores the main problem afflicting contextualism, what I call the "Generality Objection." Part 2 presents and defends both KAA and a powerful new positive argument that it provides for contextualism. Part 3 uses KAA to answer the Generality Objection, and also casts other shadows over the prospects for anti-contextualism.

This paper brings together two positions that for the most part have been developed and defended independently of one another: contextualism about knowledge attributions and the knowledge account of assertion.

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. (shrink)

Keith DeRose gives an invalid argument for contextualism in “Assertion, Knowledge, and Context.” In section 2.4, entitled “The Argument for Contextualism,” DeRose makes the following remarks. “The knowledge account of assertion provides a powerful argument for contextualism: If the standards for when one is in a position to warrantedly assert that P are the same as those that comprise a truth-condition for ‘I know P,’ then if the former vary with context, so do the latter. In short: The knowledge account (...) of assertion together with the context-sensitivity of assertability yields contextualism about knowledge”. (shrink)
