Recent epistemology divides theories of knowledge according to their diagnoses of cases of failed knowledge, Gettier cases. Two rival camps have emerged: naturalism and justificationism. Naturalism attributes the failure of knowledge in these cases to the cognizer's failure to stand in a strong natural position vis-à-vis the proposition believed. Justificationism traces the failure to the cognizer's failure to be strongly justified in his belief. My aim is to reconcile these camps by offering a version of naturalism, a reliability theory of (...) knowledge, that conforms to the central justificationist tenets. I argue that proposed reliability theories of knowledge, reliable indication theories, offer no prospect of a reconciliation because they misdiagnose failed knowledge in such a way as to violate a basic justificationist tenet. Proposed versions of justificationism, it turns out, fare no better with this tenet. I offer an alternative reliability theory of knowledge, a reliable process theory, that conforms to the justificationist tenet. (shrink)

Reliabilist theories propose to analyse epistemic justification in terms of reliability. This paper argues that if we pay attention to the details of probability theory we find that there is no concept of reliability that can possibly play the role required by reliabilist theories. A distinction is drawn between the general reliability of a process and the single case reliability of an individual belief, And it is argued that neither notion can serve the reliabilist adequately.

This paper proposes a new externalist account of defeaters, in terms of reliable indicators, as an integral part of a unified externalist account of warrant and defeat. It is argued that posing externalist conditions on warrant, but internalist conditions on defeat lead to undesirable tensions. The proposal is contrasted to some rival accounts and then tested on some widely discussed cases, like the airport case. Misleading defeaters, where Laurence BonJour’s reliable clairvoyants serve as examples, also receive treatment, partly because they (...) illustrate how internalist constraints are inserted into the set up of the problem and therefore unduly constrain the domain of satisfactory solutions. Lastly, the proposal is defended against some objections. Firstly, that by posing externalist conditions on defeat, the account becomes too open. Secondly, that an externalist account fails to take into account the epistemic assessments of our fellows in the epistemic practice of forming beliefs and making epistemic claims, which can be based on accessible warrant only.

In “A well-founded solution to the generality problem,” Comesaña argues, inter alia, for three main claims. One is what I call the unavoidability claim: Any adequate epistemological theory needs to appeal, either implicitly or explicitly, to the notion of a belief’s being based on certain evidence. Another is what I call the legitimacy claim: It is perfectly legitimate to appeal to the basing relation in solving a problem for an epistemological theory. According to Comesaña, the legitimacy claim follows straightforwardly from (...) the unavoidability claim. The third one is what I call the basing solution claim: An appeal to the notion of basing relation is all we need to solve the generality problem for (process) reliabilism. In this paper, I will argue that the unavoidability claim and the basing solution claim are false and that the legitimacy claim might be true only in a qualified sense. (shrink)
