It is argued that neither contextualism nor relativism can provide a satisfying semantics of knowledge ascriptions. According to contextualism, the truth conditions of knowledge ascriptions of the form “S knows that p” vary with the epistemic standards operative in the contexts of utterance. These epistemic standards are determined, in particular, by the speaker’s stakes with regard to p or the consideration of error-possibilities. It is shown that the absolute concept of utterance truth together with a knowledge rule of assertion lead (...) to certain unassertable truths in contextualism and to counterintuitive results with regard to certain cross-context knowledge ascriptions. Although utterance truth is relativized to contexts of assessment in relativist accounts of knowledge, relativism still makes inadequate semantic predictions. In particular, relativism runs into problems in cases where the context of assessment is lower than the context of utterance. It is finally argued that invariantist accounts, according to which the truth conditions of knowledge ascriptions do neither vary with the context of utterance nor the context of assessment, but are determined by objective features given in the situation in which the knowledge claim is made, are better suited for modelling the semantics of knowledge ascriptions. Besides the fact that stakes or the consideration of error-possibilities can have an influence on the belief in a proposition, they have no further bearing on the truth conditions of knowledge ascriptions.

Intellectualists claim that knowing how to do something is a matter of knowing, for some w, that w is a way to do that thing. However, standard accounts fail to account for the way that knowing how sometimes seems to require ability. I argue that the way to make sense of this situation is via a ‘subject-specific’ intellectualism according to which knowing how to do something is a matter of knowing that w is a way for some relevant person to (...) do that thing, but who the relevant person is can change from context to context. If it is the utterer themselves, then knowing how will require ability, but otherwise it will not. (shrink)

Contextualism in epistemology has traditionally been understood as the view that “know” functions semantically like an indexical term, encoding different contents in contexts with different epistemic standards. But the indexical hypothesis about “know” faces a range of objections. This article explores an alternative version of contextualism on which “know” is a semantically stable term, and the truth-conditional variability in knowledge claims is a matter of pragmatic enrichment. The central idea is that in contexts with stringent epistemic standards, knowledge claims are (...) narrowed: “know” is used in such contexts to make assertions about particularly demanding types of knowledge. The resulting picture captures all of the intuitive data that motivate contextualism while sidestepping the controversial linguistic thesis at its heart. After developing the view, the article shows in detail how it avoids one influential linguistic objection to traditional contextualism concerning indirect speech reports, and then answers an objection concerning the unavailability of certain types of clarification speeches.

Contextualism, in its standard form, is the view that the truth conditions of sentences of the form ‘S knows that P’ vary according to the context in which they are uttered. One possible objection to contextualism appeals to what Keith DeRose calls a warranted assertability maneuver (or WAM), according to which it is not our knowledge sentences themselves that have context-sensitive truth conditions, but what is pragmatically conveyed by the use of such sentences. Thus, proponents of WAMs argue, the context (...) sensitivity of knowledge attributions is not a semantic phenomenon but a pragmatic one. I examine a number of WAMs and show that each (i) is seriously flawed, or (ii) undercuts standard contextualism if we hold a minimalist conception of semantic content. I propose an alternative form of contextualism that accommodates minimalism and is immune to the second type of WAM, and show that this new form of contextualism shares the virtues of standard contextualism.

Philosophers on all sides of the contextualism debates have had an overly narrow conception of what semantic context sensitivity could be. They have conflated context sensitivity (dependence of truth or extension on features of context) with indexicality (dependence of content on features of context). As a result of this conflation, proponents of contextualism have taken arguments that establish only context sensitivity to establish indexicality, while opponents of contextualism have taken arguments against indexicality to be arguments against context sensitivity. Once these (...) concepts are carefully pulled apart, it becomes clear that there is conceptual space in semantic theory for nonindexical forms of contextualism that have many advantages over the usual indexical forms.

Based on the brain in a vat thought experiment, skeptics argue that we cannot have certain knowledge. At the same time, we do have the intuition that we know some things with certainty. A way to justify this intuition is given by semantic contextualists who argue that the word “knows” is context sensitive. However, many have objected to the intelligibility of this claim. In response, another approach called “moderate pragmatic contextualism” was invoked, which claims that “knows” itself is not context (...) sensitive, but knowledge assertions are. I show, however, that to refute skepticism, moderate pragmatic contextualism rests on unjustified and implausible assumptions as well. Since no form of contextualism works as a response to skepticism, I argue that we should simply accept skepticism. However, I argue that skepticism is not a problem because skeptic pragmatic contextualism can offer a plausible explanation of why we have the intuition that our ordinary knowledge claims are true, even though they are not. I conclude that skeptic pragmatic contextualism offers the most plausible response to the brain in a vat thought experiment. (shrink)

There is a widespread assumption that ordinary language philosophy was killed off sometime in the 1960s or 70s by a combination of Gricean pragmatics and the rapid development of systematic semantic theory. Contrary to that widespread assumption, however, contemporary versions of ordinary language philosophy are alive and flourishing, but going by various aliases—in particular (some versions of) "contextualism" and (some versions of) "experimental philosophy". And a growing group of contemporary philosophers are explicitly embracing the methods as well as the title (...) of ordinary language philosophy and arguing that it has been unfairly maligned and was never decisively refuted. In this overview, I will outline the main projects and arguments employed by contemporary ordinary language philosophers, and make the case that updated versions of the arguments made by ordinary language philosophers in the middle of the twentieth century are attracting renewed attention.

In the past few years there has been a turn towards evaluating the empirical foundation of epistemic contextualism using formal (rather than armchair) experimental methods. By-and-large, the results of these experiments have not supported the original motivation for epistemic contextualism. That is partly because experiments have only uncovered effects of changing context on knowledge ascriptions in limited experimental circumstances (when contrast is present, for example), and partly because existing experiments have not been designed to distinguish between contextualism and one of (...) its main competing theories, subject-sensitive invariantism. In this paper, we discuss how a particular, "third-person", experimental design is needed to provide evidence that would support contextualism over subject-sensitive invariantism. In spite of the theoretical significance of third-person knowledge ascriptions for debates surrounding contextualism, no formal experiments evaluating such ascriptions that assess contextualist claims have previously been conducted. In this paper, we conduct an experiment specifically designed to examine that central gap in contextualism’s empirical foundation. The results of our experiment provide crucial support for epistemic contextualism over subject-sensitive invariantism. (shrink)

An overview of contemporary debates and topics in epistemology.

I discuss three understandings of the idea of “Knowledge First Epistemology”, i.e. Timothy Williamson’s suggestion that we should take knowledge as a starting point, rather than trying to analyze it. Some have taken this to be a suggestion about the role of the concept of knowledge, but Williamson also seems to be concerned with intuition-based metaphysics. As an alternative, I develop the idea that knowledge may be a social kind that can be understood through a functional analysis in the tradition (...) of Edward Craig. (shrink)
