John McDowell has recently changed his line of response to philosophical scepticism about the external world. He now claims to be in a position to use the strategy of transcendental argumentation in order to show the falsity of the sceptic’s misrepresentation of our ordinary epistemic standpoint. Since this transcendental argument begins from a weak and widely shared assumption shared with the sceptic herself the falsity of external world scepticism is now demonstrable even to her. Building on the account of perceptual (...) intentionality defended in the Woodbridge lectures, McDowell argues that the idea of narrow perceptual content is unavailable to anyone, including the sceptic. This argument is assessed by drawing out an analogy with parallel responses to error theories in ethics. (shrink)

1. In this exciting and ambitious book, Duncan Pritchard defends a novel conception of perceptual epistemic grounds, which can both be factive and reflectively available to the agent. Pritchard calls this position the ‘holy grail’ of epistemology for its power to undercut two of contemporary epistemology’s most central problems: the epistemic internalism/externalism controversy and radical scepticism. While Pritchard’s book manages to make a convincing case for why one should accept epistemological disjunctivism (ED), the ‘neo-Moorean’ anti-sceptical strategy that he derives from (...) it is less compelling. This is not because ED does not provide us with the materials for a plausible anti-sceptical strategy, however, but rather because Pritchard misidentifies where ED’s real power lies, namely, in its potential to prevent the radical sceptical problem from arising in the first place. If I am right, then there is no need to establish Moore-type anti-sceptical theses with the ground rules for doing so set by scepticism. For once (and as McDowell has maintained) the thought has been undermined that my perceptual epistemic grounds can only ever consist of the ‘highest common factor’ between the ‘good case’ and the ‘bad case’, the traditional route to radical scepticism is blocked.

Epistemological disjunctivists make appeal to Moorean-style anti-skeptical arguments. It is often held that one problem with using Moorean-style arguments in the context of a response to skepticism is that such arguments are subject to a kind of epistemic circularity. The specific kind of epistemic failure involved has come to be known as a failure of warrant transmission. It would likely pose a problem for the anti-skeptical ambitions of the epistemological disjunctivist if his version of the Moorean-style argument failed to transmit (...) warrant; but no epistemological disjunctivist has offered an argument to show that this is not so. In this paper, I fill the gap by arguing that warrant transmits across epistemological disjunctivist Moorean-style arguments. (shrink)

Epistemological disjunctivism, as defended by, for example, McDowell, Neta and Pritchard, is the view that epistemic justification can be – and in paradigmatic cases of perceptual knowledge actually is – both factive and reflectively accessible. One major problem for this view is the access problem: apparently, epistemological disjunctivism entails that ordinary external world propositions can be known by reflection alone. According to epistemological disjunctivism, seeing that the sun is shining is reflectively accessible and seeing that the sun is shining entails (...) that it is. Assuming closure of reflective knowledge under known entailment it is also reflectively knowable that the sun is shining. Drawing on joint work with Neta, Pritchard replies that disjunctivism is not committed to this absurdity, but only to the possibility of reflective access to empirical reasons. In this article I offer an interpretation of this reply, but also an objection to it: my interpretation is based on applying the source/content distinction to epistemic reasons. My objection is based on arguing that the access problem is a problem for any version of access internalism. Although Pritchard's reply solves the general access problem, it does not solve the access problem that is generated by the specific commitments of epistemological disjunctivism. Due to the transparency of self-knowledge of propositional perception, epistemological disjunctivism cannot meet a central requirement for applying the source/content distinction. (shrink)

In this article, I define and then defend the principle of information closure (pic) against a sceptical objection similar to the one discussed by Dretske in relation to the principle of epistemic closure. If I am successful, given that pic is equivalent to the axiom of distribution and that the latter is one of the conditions that discriminate between normal and non-normal modal logics, a main result of such a defence is that one potentially good reason to look for a (...) formalization of the logic of “ $S$ is informed that $p$ ” among the non-normal modal logics, which reject the axiom, is also removed. This is not to argue that the logic of “ $S$ is informed that $p$ ” should be a normal modal logic, but that it could still be insofar as the objection that it could not be, based on the sceptical objection against pic, has been removed. In other word, I shall argue that the sceptical objection against pic fails, so such an objection provides no ground to abandon the normal modal logic B (also known as KTB) as a formalization of “ $S$ is informed that $p$ ”, which remains plausible insofar as this specific obstacle is concerned.

The grounding or motivating intuitions behind internalism and externalism seem to be fundamentally at odds. If there is ever to be a viable or satisfying solution to the problem, it must satisfy the grounding intuitions behind both sides of the debate. Duncan Pritchard claims his theory of epistemological disjunctivism (ED) does just this, arguing that it could be the holy grail we have all been waiting for. However, I believe the holy grail is already out there in the form of (...) the theory that knowledge is a mental state (KMS). In this article, I defend the idea the KMS is far better able to satisfy the internalist and externalist intuitions than ED. (shrink)

The topic of this paper may be introduced by fast zooming in and out of the philosophy of information. In recent years, philosophical interest in the nature of information has been increasing steadily. This has led to a focus on semantic information, and then on the logic of being informed, which has attracted analyses concentrating both on the statal sense in which S holds the information that p (this is what I mean by logic of being informed in the rest (...) of this article) and on the actional sense in which S becomes informed that p. One of the consequences of the logic debate has been a renewed epistemological interest in the principle of information closure (henceforth PIC), which finally has motivated a revival of a skeptical objection against its tenability first made popular by Dretske. This is the topic of the paper, in which I seek to defend PIC against the skeptical objection. If I am successful, this means – and we are now zooming out – that the plausibility of PIC is not undermined by the skeptical objection, and therefore that a major epistemological argument against the formalization of the logic of being informed based on the axiom of distribution in modal logic is removed. But since the axiom of distribution discriminates between normal and non-normal modal logics, this means that a potentially good reason to look for a formalization of the logic of being informed among the non-normal modal logics, which reject the axiom, is also removed. And this in turn means that a formalization of the logic of being informed in terms of the normal modal logic B (also known as KTB) is still very plausible, at least insofar as this specific obstacle is concerned. In short, I shall argue that the skeptical objection against PIC fails, so it is not a good reason to abandon the normal modal logic B as a good formalization of the logic of being informed. (shrink)
