Duncan Pritchard’s Epistemic Angst promises a novel solution to the closure-based sceptical problem that, unlike more traditional solutions, does not entail revising our fundamental epistemological commitments. In order to do this, it appeals to a Wittgensteinian account of rational evaluation, the overarching theme of which is that it neither makes sense to doubt nor to believe in our anti-sceptical hinge commitments. The purpose of this paper is to show that the argument for the claim that there can be no rational (...) basis to believe our anti-sceptical hinge commitments relies upon an implicit assumption about rational support that I label The Pritchensteinian Rational Grounds Principle. I argue that, insofar as this principle is intended to apply to closure-style inferences, it leads to irrational doxastic attitudes. I consider a seemingly plausible modification of the principle that would avoid this result but show that this modified principle faces serious problems of its own. -/- . (shrink)

A prima facie plausible and widely held view in epistemology is that the epistemic standards governing the acquisition of testimonial knowledge are stronger than the epistemic standards governing the acquisition of perceptual knowledge. Conservatives about testimony hold that we need prior justification to take speakers to be reliable but recognise that the corresponding claim about perception is practically a non-starter. The problem for conservatives is how to establish theoretically significant differences between testimony and perception that would support asymmetrical epistemic standards. (...) In this paper I defend theoretical symmetry of testimony and perception on the grounds that there are no good reasons for taking these two belief forming methods to have significant theoretical differences. I identify the four central arguments in defence of asymmetry and show that in each case either they fail to establish the difference that they purport to establish or they establish a difference that is not theoretically significant.

A certain brand of skeptical argument appeals to the thought that our inability to subjectively discriminate between competing hypotheses means that we are unwarranted in believing in either. Externalists respond by pointing out that such arguments depend on an internalist conception of warrant that we would do well to reject. This strategy has been criticised by Crispin Wright who argues that if we pursue the implications of externalism sufficiently far we find that it is ultimately unstable or incoherent. I first (...) rehearse the simple externalist anti-skeptical position. I then present Wright’s argument for the externalist instability, offering a clearer way of understanding its central claim. Finally, I show that the instability in fact arises due to hidden internalist assumptions about evidence and that rid of these assumptions the externalist position is stable after all. (shrink)

In this paper I argue that entitlement theorists face a dilemma, the upshot of which is that entitlement theory is either unmotivated or incoherent. I begin with the question of how confident one should be in a proposition on the basis of an entitlement to trust, distinguishing between strong views that warrant certainty and weak views that warrant less than certainty. Strong views face the problem that they are incompatible with the ineliminable epistemic risk that is a feature of the (...) two main arguments in support of entitlement theory, the Strategic and Cognitive Project models. I then distinguish further between two types of weak views, arguing that both ultimately lead to condoning irrational doxastic attitudes. I end by considering whether entitlement theorists can avoid these issues by rejecting the assumption that entitlements to trust are warrants to adopt degrees of confidence. I argue that this strategy fails and note that entitlement theorists themselves explicitly endorse degree-of-confidence views. (shrink)

In response to the claim that certain epistemically defective inferences such as Moore’s argument lead us to the conclusion that we ought to abandon closure, Crispin Wright suggests that we can avoid doing so by distinguishing it from a stronger principle, namely transmission. Where closure says that knowledge of a proposition is a necessary condition on knowledge of anything one knows to entail it, transmission makes a stronger claim, saying that by reasoning deductively from known premises one can thereby acquire (...) knowledge of or justification for the conclusion. Wright’s thought is that in cases such as Moore what is really going on is a failure of transmission, not a failure of closure. The problem with this claim is that it relies on an outdated formulation of closure which few nowadays would find plausible. Once we stipulate that it is the intuitive closure principle that deserves our attention, it becomes far less obvious that the project of diagnosing what is wrong with arguments such as Moore in terms of transmission failure but not closure failure can be vindicated. In order to demonstrate this claim, I consider intuitive closure of propositional justification vs. transmission of propositional justification and concede that perhaps these can come apart in the way that Wright suggests. I then argue that despite this concession, we also need an answer to the question of whether intuitive closure for doxastic justification and transmission for doxastic justification can come apart. We need an answer to this question because our ultimate interest in these issues stems from our interest in whether knowledge obeys closure, not merely whether propositional justification does. I argue that, even on the assumption that there is transmission failure of propositional justification, there is no transmission failure of doxastic justification. And if this is true, then there is no transmission failure of knowledge either. The transmission failure diagnosis of Moore’s argument and its ilk is thus in trouble. (shrink)

This project is concerned with the attempt to diagnose certain types of deductive inferences as exhibiting failure of transmission of justification. The canonical example of alleged transmission failure is G. E. Moore’s infamous ‘proof’ of the external world, in which Moore reasoned here is a hand, therefore the external world exists. If the transmission failure diagnosis is correct, then this inference is incapable of providing a route to learning of its conclusion on the grounds that it is only if one (...) already has some justification to believe its conclusion that one can acquire justification for its premise. The thesis presents two novel problems for the transmission failure diagnosis. Firstly, this diagnosis is only appealing if it is able to safeguard epistemic closure, but it is unclear whether it is able to do this once we distinguish between propositional and doxastic justification. Secondly, a dilemma is presented for entitlement theory, the traditional framework for understanding how there could be justification for believing the conclusions at issue. The dilemma arises once we consider the question of what the apposite degree of confidence is that is licenced by an entitlement, the upshot of which is that either entitlement theory is unmotivated, or it leads to irrational doxastic attitudes. In light of these problems, an alternative framework for understanding the phenomenon of transmission failure is presented. This framework rejects a common assumption in the literature that we can only accommodate the phenomenon by appealing to internalist notions of justification. The resulting externalist framework is defended against two potentially devastating objections. Finally, implications for how these views regarding the structure of justification bear on issues in the epistemology of testimony are considered, and it is argued that a certain family of views in the literature on testimony are committed to certain problematic views regarding the structure of justification.

This volume features new perspectives on the topic of epistemic closure. It connects epistemic closure principles to related themes in epistemology such as scepticism, dogmatism, evidentialism, epistemic logic, and modal epistemology.
