Skepticism is one of the perennial problems of philosophy: from antiquity, to the early modern period of Descartes and Hume, and right through to the present day. It remains a fundamental and widely studied topic and, as Annalisa Coliva and Duncan Pritchard show in this book, it presents us with a paradox with important ramifications not only for epistemology but also for many other core areas of philosophy. In this book they provide a thorough grounding in contemporary debates about skepticism, exploring the following key topics: the core skeptical arguments, with a particular focus on Cartesian and Humean radical skepticism. the epistemic principles that are held to underlie skeptical arguments, such as the closure and underdetermination principles. the content externalism of Putnam, Davidson and Chalmers, and how it might help us respond to radical skepticism. the epistemic externalism/internalism distinction and how it relates to the skeptical problematic. contextualism in epistemology and its anti-skeptical import. the various interpretations of a Wittgensteinian hinge epistemology. the viability of epistemological disjunctivism, including whether it can be combined with hinge epistemology as part of a dual response to radical skepticism. liberal and conservative responses to the Humean skeptical paradox. Both authors are themselves prominent figures who work on skepticism, and so one novelty of the book is that it provides an insight into their own contrasting responses to this philosophical difficulty. With the addition of annotated further reading and a glossary this is an ideal starting point for anyone studying the philosophy of skepticism, along with students of epistemology, metaphysics and contemporary analytic philosophy.

This paper deals with the question whether, and to what extent, perceptions can provide a justification for our empirical beliefs. In particular, it addresses the issue of whether they need to be conceptualized by a subject in order to play a justificatory role. It is argued that the conditions under which a subject can have perceptual representational contents and those under which those representational contents can play a justificatory role differ. The upshot is that perception can provide justification only for the beliefs of those creatures who have a conceptual apparatus and are therefore in a position passively to exercise it in perception, even though also creatures devoid of concepts can and often do have perceptual representations.

The paper presents an extension of the kind of hinge epistemology proposed in Extended Rationality. A Hinge Epistemology (Coliva 2015) to the case of testimonial justification. This extension stems naturally from a reinterpretation of the classic dispute between reductionists and anti-reductionists with respect to testimonial justification. The interesting and novel aspect of that reinterpretation is that it brings to light the deep analogy between that classic dispute and the contemporary debate between so-called “liberals” and “conservatives” with respect to the structure of perceptual justification. The paper first presents the reinterpretation; it subsequently proposes the extension of hinge epistemology to the case of testimonial justification; it then turns to a detailed discussion of the exact “hinges” testimonial justification is taken to depend on, and closes by considering some possible objections.

This chapter serves as an opinionated introduction to the problem of convergence (that there is no clear convergence to the truth in philosophy) and the problem of peer disagreement (that disagreement with a peer rationally demands suspending one’s beliefs), and some of the issues they give rise to, namely, philosophical skepticism and progress in philosophy. After introducing both topics and surveying the various positions in the literature we explore the prospects of an alternative, hinge-theoretic account.

The paper analyses the discussion in the last decades on whether perceptions can, as such, justify empirical beliefs, and develops it along two fundamental lines: the nature of perceptual content and the nature of the justifications in play. Starting with Sellars' attack on the «Myth of the given», it examines Davidson's, McDowell's, Peacocke's and Burge's positions. On the one hand, it contends that also creatures that aren't endowed with the relevant concepts can have genuine perceptions; on the other, that only when the latter are conceptualized, they can, as such, justify the corresponding empirical beliefs.

The aim of the paper is to bring out exactly what makes first-personal contents special, by showing that they perform a distinctive cognitive function. Namely, they are stopping points of inquiry. First, I articulate this idea and then I use it to clear the ground from a troublesome conflation. That is, the conflation of this particular function all first-person thoughts have with the property of immunity to error through misidentification, which only some I-thoughts enjoy. Afterward, I show the implications of this idea for a theory of first-person content and of immunity to error though misidentification. I then make some comparisons with Pryor’s notion of wh-misidentification and immunity thereof and with Cappelen and Dever’s position on immunity to error through misidentification and show why they are defective.

This chapter examines the distinction between practical and propositional knowledge. It then considers the objections put forward by Stanley and Williamson and finds them wanting. Afterwards, it presents Chomsky’s position on linguistic competence as a form of propositional knowledge. It criticizes both the theoretical and the empirical arguments Chomsky puts forward in favor of his view and presents some observations in favor of the idea that linguistic competence is ultimately practical. In so doing, it aims to re-habilitate the picture of practical knowledge and of linguistic competence endorsed, arguably, by Wittgenstein and Ryle.

In this paper I address the question of whether the fact that our colour experiences have a finer-grained content than our ordinary colour concepts allow us to represent should be taken as a threat to theories of the conceptual content of experience. In particular, I consider and criticise McDowell's response to that argument and propose a possible development of it. As a consequence, I claim that the role of the argument from the finer-grained content of experience has to be redefined. In particular, I acknowledge that this problem is helpful in order to bring to the fore the issue of the proper characterisation of the constraints upon the possession conditions of perceptual demonstrative concepts. Yet, I contend that, in light of the foregoing discussion, it is neutral with respect to the dispute between conceptual and non-conceptual theorists. For that dispute hinges on whether it is possible to have experiences with a certain content independently of having the concepts, which are needed for its canonical specification and not on whether those experiences are conceptualisable in all their finesse of grain.

The paper illustrates and clarifies the distinction between first-personal and third-personal self-knowledge. It is argued that the characteristic traits of first-personal self-knowledge are groundlessness, transparency and authority. It is maintained that each of these characteristics is a necessary and a priori aspect of first-personal self-knowledge.The thesis that there is first-personal self-knowledge is then defended from challenges coming from cognitive science, which are taken to show that we may fail to know dispositional (sometimes causal) elements of our mental states. Yet, this does not impugn the fact that, regarding the non-dispositional aspects of our mental life, we can and do have first-personal knowledge of them.It is then argued that third-personal self-knowledge is achieved through a plurality of methods, which vary from inference to the best explanation, to induction, simulation, testimony and inferential conceptual deployment. The ensuing self-ascriptions are therefore neither groundless, nor transparent or authoritative and are the result of substantive cognitive achievements.

Extended Rationality: A Hinge Epistemology provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea in On Certainty that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address major problems in epistemology, such as the nature of perceptual justifications, external world skepticism, epistemic relativism, the epistemic status of basic logical laws, of the Principle of the Uniformity of Nature, of our belief in the existence of the past and of other minds, and the nature of testimonial justification. Along the way, further technical issues, such as the scope of the Principle of Closure of epistemic operators under known entailment, the notion of transmission failure, and the existence of entitlements are addressed in new and illuminating ways.

_ Source: _Volume 6, Issue 2-3, pp 73 - 78 This introduction gives a summary of the content of the special issue _Hinge Epistemology_, grouping the papers in three sections: more exegetical accounts of Wittgenstein’s notion of hinge certainties and their bearing on a theory of justification and knowledge as well as on the topic of external world scepticism; papers critical of the very notion of hinge certainty; and papers that apply the notion to various areas of epistemology and compare Wittgenstein’s views to those of other philosophers.

In the last few years there has been a resurgence of interest in Moore’s Proof of the existence of an external world, which is now often rendered as follows:1 (I) Here’s a hand (II) If there is a hand here, there is an external world Therefore (III) There is an external world The contemporary debate has been mostly triggered by Crispin Wright’s influential—conservative —“Facts and certainty” and further fostered by Jim Pryor’s recent—liberal—“What’s wrong with Moore’s argument?”.2 This debate is worth surveying with care because—so I shall contend—it will help us see that, in fact, it allows for an important view that, so far, hasn’t been explicitly considered. The critical survey will be the task of the next two sections, while, in the remaining..
