According to a widely discussed view, knowledge plays a significant normative role in action: It is epistemically rational to treat p as your reason for action if and only if you know that p. As many philosophers have observed, however, this view clashes with the claim that knowledge is moderate and stable. For, granting that claim, there will be high stakes cases in which knowledge seems insufficient. To deal with such cases, some philosophers embracing the knowledge norm combine three independently (...) plausible claims. First, they say that no non-trivial condition is luminous; second, they say that doing something while not being in a position to know that that is appropriate is bad (in high stakes cases); third, they say that in the high stakes cases in question, the subject knows but fails to be in a position to know that she knows (Williamson Philos Q 55:213–235, 2005). This paper argues that this account can overcome the main objections already raised in the literature, but that it still faces the apparently insurmountable challenge of providing a natural and helpful way of substantiating the second claim.

I review proposed skepticisms in recent literature (or skeptical invariantisms, if we understand skepticism semantically), contrast their basic commitments and highlight some of their comparative theoretical attractions and problems. To help set the scene for the discussion, I start with Unger’s (1975) modern classic of global skepticism about knowledge (and justification). I then distinguish three extant categories of skepticism in the recent literature: two non‐traditional and one more traditional. On the non‐traditional side are fallibilist science‐based skepticism (which relaxes thestringencyof the (...) standard of knowledge) and practical skepticism (which questions theintellectualcharacter of the standard of knowledge) and on the traditional side high‐standard/infallibilist. I then briefly present and discuss representatives of each category. (shrink)

AbstarctIn the first installment of Varieties of Skeptical Invariantism, we set the scene for subsequent discussion with Unger's (1975) modern classic of global skepticism and distinguished three varieties of skeptical invariantism in recent literature: traditional skeptical invariantism, fallibilist science-based skepticism and practical skepticism. We then presented fallibilist science-based skepticism, that is, the position that relaxes the stringency of the standard of knowledge but still questions parts of our everyday knowledge on the basis of scientific reasons. In particular, we presented Frances’ (...) (2005) ‘live’ skepticism and Hannon's (forthcoming) ‘hard-hitting’ skepticism. In this second installment, we present the two other varieties of skeptical invariantism we identified: traditional skepticism (high-standard and infallibilist) that respects all three commitments (intellectualism, invariantism, stringency) and practical skepticism that questions the intellectualist commitment.

In this paper, we propose a general constraint on theories of knowledge that we call ‘normalism’. Normalism is a view about the epistemic threshold that separates knowledge from mere true belief; its basic claim is that one knows only if one has at least a normal amount of epistemic support for one’s belief. We argue that something like normalism is required to do full justice to the normative role of knowledge in many key everyday practices, such as assertion, inquiry, and (...) testimony. The view of normality we employ to flesh out this claim is inspired by experimental work on the folk notion of normality, which suggests that folk judgments of what is ‘normal’ are based upon both statistical averages as well as normative ideals within the relevant target domain. Adopting this notion of normality to set the threshold for knowledge results in a view upon which knowledge is routinely available on an everyday basis without being a merely trivial achievement. We explore several interesting consequences of this view, including the implication that the threshold for knowing may change as, e.g., the ease of availability of information in an epistemic community changes over time. The result is a ‘shifty’ view of knowledge which nonetheless retains more stability than standard contextualist or pragmatic encroachment approaches. (shrink)

According to evidentialist views, credence in a proposition p should be proportional to the degree of evidential support that one has in favor of p. However, empirical evidence suggests that our credences are systematically sensitive to practical factors. In this article, I provide a cost–benefit analysis of credences' practical sensitivity. The upshot of this analysis is that credences sensitive to practical factors fare better than practically insensitive ones along several dimensions. All things considered, our credences should be sensitive to practical (...) factors. (shrink)

According to the Rational Threshold View, a rational agent believes p if and only if her credence in p is equal to or greater than a certain threshold. One of the most serious challenges for this view is the problem of statistical evidence: statistical evidence is often not sufficient to make an outright belief rational, no matter how probable the target proposition is given such evidence. This indicates that rational belief is not as sensitive to statistical evidence as rational credence. (...) The aim of this paper is twofold. First, we argue that, in addition to playing a decisive role in rationalizing outright belief, non-statistical evidence also plays a preponderant role in rationalizing credence. More precisely, when both types of evidence are present in a context, non-statistical evidence should receive a heavier weight than statistical evidence in determining rational credence. Second, based on this result, we argue that a modified version of the Rational Threshold View can avoid the problem of statistical evidence. We conclude by suggesting a possible explanation of the varying sensitivity to different types of evidence for belief and credence based on the respective aims of these attitudes. (shrink)

Are all epistemic notions – including evidence and rational credence – sensitive to practical considerations? A number of philosophers have argued that the answer must be ‘No’, since otherwise rational agents would be susceptible to diachronic Dutch books. After unpacking this challenge, I show how it can be resisted by appealing to an analogy between shifting stakes and memory loss. The upshot: pervasive epistemic shiftiness may be tenable after all.

This book takes purism about knowledge as the default position and defends it from the challenges of pragmatic encroachment. The book is divided into two parts, a negative and a positive one. The negative part critically examines existing purist strategies in response to pragmatic encroachment. The positive part provides a new theory of how practical factors can systematically influence our confidence and explores some implications of such influence.

Skeptical invariantism isn’t a popular view about the semantics of knowledge attributions. But what, exactly, is wrong with it? The basic problem is that it seems to run foul of the fact that we know quite a lot of things. I agree that it is a key desideratum for an account of knowledge that it accommodate the fact that we know a lot of things. But what sorts of things should a plausible theory of knowledge say that we know? In (...) this paper I sketch an answer to this question and then apply it to skeptical invariantism. I start by distinguishing between a “radical” skeptical invariantist position (on which the standards for knowing are so high that we rarely if ever satisfy them) and a more “moderate” skeptical invariantist position (on which the standards are very hard, but not impossible, to satisfy). I then argue that, while radical forms of skeptical invariantism are clearly not going to do a good job of satisfying the key desideratum, more moderate forms can do quite well with respect to it. In particular, I argue the version of moderate skeptical invariantism defended by Davide Fassio can plausibly satisfy it. (shrink)
