The ambiguity theory of ‘knows’ is the view that ‘knows’ and its cognates have more than one sense, and that which sense of ‘knows’ is used in a knowledge ascription or denial determines, in part, the meaning (and as a result the truth conditions) of that knowledge ascription or denial. In this paper, I argue that the ambiguity theory of ‘knows’ ought to be taken seriously by those drawn to epistemic contextualism. In doing so I first argue that the ambiguity (...) theory of ‘knows’ is a distinct view from epistemic contextualism. Second, I provide independent philosophical and linguistic considerations to motivate the ambiguity theory. Third, I argue that the ambiguity theory has the same central, generally agreed upon virtues ascribed to epistemic contextualism (namely, the ability to solve certain persistent epistemological problems relating to skeptical arguments and the ability to preserve the truth of most of our everyday, ordinary usages of ‘knows’ and its cognates). Finally, I provide an ambiguity-theory-friendly account of why contextualism may be initially appealing, and why this shouldn’t dissuade us from taking the ambiguity theory seriously nonetheless.

In this essay I present a new and empirically-testable strategy for completing quantum mechanics. In recent decades, urban design and architecture disciplines witnessed plenty of theories and school development. Primarily, those disciplines are inspired by philosophical perspectives. Thus, it is required to have a good deal of perception on the philosophical roots. Contextualism theory and approach is considered one of the most important controversial approaches in urban design and architecture. The present study intends to elaborate contextualism and explicate its difference (...) with other similar philosophical ideas. Subsequently, it tends to explain the epistemological and philosophical foundations of contextualism in postmodernism and Gestalt school and subsequently to elucidate its position in the postmodern art and specifically in postmodern urban design and architecture. Contextualism is an idea based on the epistemology that the meaning perceived from an epistemological sentence would differ according to the epistemological standards. The idea has three distinct uses in philosophical views, primarily, the truth condition of the sentences is come to be assessed; in the second use, the language meaning is dependent on the context. The paper indicates the first and second uses of contextualism are mostly seen in urban design and architecture contextualism theory. (shrink)

Keith DeRose and Stewart Cohen object to the fallibilist strand of pragmatic invariantism regarding knowledge ascriptions that it is committed to non-cancelable pragmatic implications. I show that this objection points us to an asymmetry about which aspects of the conveyed content of knowledge ascriptions can be canceled: we can cancel those aspects that ascribe a lesser epistemic standing to the subject but not those that ascribe a better or perfect epistemic standing. This situation supports the infallibilist strand of pragmatic invariantism (...) according to which knowledge semantically requires absolute certainty but this claim is often pragmatically weakened: it turns out that exactly those aspects of the conveyed content are cancelable that this view claims are pragmatic. I also argue that attributor contextualism and relativism do not have an alternative explanation of this phenomenon. (shrink)

How should we account for the contextual variability of knowledge claims? Many philosophers favour an invariantist account on which such contextual variability is due entirely to pragmatic factors, leaving no interesting context-sensitivity in the semantic meaning of ‘know that.’ I reject this invariantist division of labor by arguing that pragmatic invariantists have no principled account of embedded occurrences of ‘S knows/doesn’t know that p’: Occurrences embedded within larger linguistic constructions such as conditional sentences, attitude verbs, expressions of probability, comparatives, and (...) many others, I argue, give rise to a threefold problem of embedded implicatures.

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)

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)

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)

This paper explores a few of the ways that the Zhuang-Zi can inform contemporary analytic epistemology. I begin, in section 1, by briefly outlining and summarizing the case for my fictionalist interpretation of the text. In section 2, I discuss how the Zhuang-Zi can be brought into productive dialogue with the question of how we should respond to skeptical arguments. Specifically, I argue that the Zhuang-Zi can be reasonably interpreted as exemplifying an approach that is different from dominant contemporary responses (...) to skeptical arguments in three ways: it is fictionalist; it motivates a skeptical perspective rather than a claim; and it accomplishes its aims in an atypical, but nonetheless contextually appropriate, way. However, the Zhuang-Zi is relevant to contemporary debates about skeptical arguments because it can be used: to respond to the same sorts of skeptical arguments that occupy contemporary commentators; to address a number of questions that arise in connection with such arguments; and to suggest important new questions for epistemologists to pursue.

Debates regarding theory and practice in social work have often avoided detailed discussion regarding the nature of knowledge itself and the various ways this can be created. As a result, positivistic conceptions of knowledge are still assumed by many to be axiomatic, such that context-dependent and practitioner-oriented approaches to knowledge creation and use are assumed to lack epistemological rigor and credibility. By drawing on epistemology, this theoretical paper outlines the case for a renewed approach to knowledge definition, creation and use (...) within social work by reference to pragmatism. Pragmatism has the potential to act as an organizing theoretical framework, taking account of the role of both ontology and epistemology, acting as a functional methodology for the further enhancement of practice-based knowledge.
