Epistemological contextualism ‐ the claim that the truth‐value of knowledge‐attributions can vary with the context of the attributor ‐ has recently faced a whole series of objections. The most serious one, however, has not been discussed much so far: the factivity objection. In this paper, I explain what the objection is and present three different versions of the objection. I then show that there is a good way out for the contextualist. However, in order to solve the problem the contextualist (...) has to accept a relationalist version of contextualism. (shrink)

In this essay I show how to reconcile epistemic invariantism with the knowledge account of assertion. My basic proposal is that we can comfortably combine invariantism with the knowledge account of assertion by endorsing contextualism about speech acts. My demonstration takes place against the backdrop of recent contextualist attempts to usurp the knowledge account of assertion, most notably Keith DeRose's influential argument that the knowledge account of assertion spells doom for invariantism and enables contextualism's ascendancy.

The central contentions of this paper are two: first, that contextualism about knowledge cannot fulfil the eirenic promise which, for those who are drawn to it, constitutes, I believe, its main attraction; secondly, that the basic diagnosis of epistemological scepticism as somehow entrapping us, by diverting attention from a surreptitious shift to a special rarefied intellectual context, rests on inattention to the details of the principal sceptical paradoxes. These contentions are consistent with knowledge-contextualism, of some stripe or other, being true. (...) What follows will not bear directly on that. (shrink)

Abstract: Some recent arguments against the classical invariantist account of knowledge exploit the idea that there is a ‘knowledge norm’ for assertion. It is claimed that, given the existence of this norm, certain intuitions about assertability support contextualism, or contrastivism, over classical invariantism. In this paper I show that, even if we accept the existence of a knowledge norm, these assertability-based arguments fail. The classical invariantist can accommodate and explain the relevant intuitions about assertability, in a way that retains the (...) idea that knowledge is the epistemic norm for assertion. When we consider the role of assertion as a conversational act, it becomes plausible that a subject's epistemic warrant to assert can be defeated even though she has knowledge. This defeasibility thesis is what allows the classical invariantist to accommodate and explain the kinds of intuitions on which assertability-based arguments depend. (shrink)

How must knowledge be formed, if made in the image of assertion? That is, given that knowledge plays the normative role of governing what one may assert, what can be inferred about the structure of the knowledge relation from this role? I will argue that what one may assert is sensitive to the question under discussion, and conclude that what one knows must be relative to a question. In short, knowledge in the image of assertion is question-relative knowledge.

Jessica Brown effectively contends that Keith DeRose’s latest argument for contextualism fails to rule out contextualism’s chief rival, namely, classic invariantism. Still, even if her position has not been ruled out, the classic invariantist must offer considerations in favor of her position if she is to convince us that it is superior to contextualism. Brown defends classic invariantism with a warranted assertability maneuver that utilizes a linguistic pragmatic principle of relevance. I argue, however, that this maneuver is not as effective (...) as it might be. I propose a different warranted assertability maneuver—one that utilizes a pragmatic principle of strength—that affords a more successful defense of classic invariantism, and that helps to establish that classic invariantism is superior to contextualism.

Keith DeRose has recently argued that the contextual variability of appropriate assertion, together with the knowledge account of assertion, yields a direct argument that 'knows' is semantically context-sensitive. The argument fails because of an equivocation on the notion of warranted assertability. Once the equivocation is removed, it can be seen that the invariantist can retain the knowledge account of assertion and explain the contextual variability of appropriate assertion by appealing to Williamson's suggestion that practical and conversational considerations can influence the (...) extent to which adherence to the constitutive norm of assertion matters.

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)
