What is at the center of the epistemology of testimony: reliability or knowledge? This is the key question that Elizabeth Fricker takes up in her “How to Make Invidious Distinctions Amongst Reliable Testifiers.” In particular, Fricker argues that there are several important reasons to favor understanding testimonial knowledge in terms of the speaker being a knower rather than merely a reliable source of information. In this short response, I raise problems for Fricker’s view and the arguments put forth to support it. I conclude that contrary to Fricker’s thesis, the epistemology of testimony should focus on speaker reliability rather than knowledge.

Orthodoxy has it that knowledge is a composite of belief and non-mental factors. However, Timothy Williamson suggests that orthodoxy implies that the concept of belief is acquired before the concept of knowledge, whereas developmental data suggest the reverse. More recently, Jennifer Nagel reviews the psychological evidence, building a psychological case that the concept of knowledge emerges prior to belief. I assess the psychological state of the art and find support for the opposite conclusion. Overall the empirical evidence supports the orthodox view that the concept of belief is prior to the concept of knowledge.

The field of experimental philosophy has received considerable attention, essentially for producing results that seem highly counter-intuitive and at the same time question some of the fundamental methods used in philosophy. One of the earlier influential papers that gave rise to the experimental philosophy movement titled ‘Normativity and Epistemic Intuitions’ by Jonathan M. Weinberg, Shaun Nichols and Stephen Stich (2001), reported that respondents displayed different epistemic intuitions depending on their ethnic background as well as socioeconomic status. These findings, if robust, would have important implications for philosophical methodology in general and epistemology in particular. Because of the important implication of its findings, Weinberg et al. (2001) has been very influential – currently with more than four hundred citations – and the subject of extensive debate. Despite the paper's significance and despite all the debates this paper has generated, there has not been a replication attempt of its experiments. We collected data from four different sources (two on-line and two in-person) to replicate the experiments. Despite several different data sets and in various cases larger sample sizes, we failed to detect significant differences between the above-mentioned groups. Our results suggest that epistemic intuitions are more uniform across ethnic and socioeconomic groups than Weinberg et al. (2001) indicates. Given our data, we believe that the notion of differences in epistemic intuitions among different ethnic and socioeconomic groups advanced by Weinberg et al. (2001) and accepted by many researchers needs to be corrected.

We discuss the role of practical costs in the epistemic justification of a novice choosing expert advice, taking as a case study the choice of an expert statistician by a lay politician. First, we refine Goldman's criteria for the assessment of this choice, showing how the costs of not being impartial impinge on the epistemic justification of the different actors involved in the choice. Then, drawing on two case studies, we discuss in which institutional setting the costs of partiality can play an epistemic role. This way we intend to show how the sociological explanation of the choice of experts can incorporate its epistemic justification.

Carroll's (1895) short piece “What the Tortoise said to Achilles” in many ways anticipates issues that arise in a number of contemporary controversies. One might argue, for example, that initially plausible attempts to deal with the problem of easy knowledge will land one in the unfortunate position of Achilles who followed the Tortoise down a road that leads to vicious infinite regress. Or consider the conditions required for inferential justification. For idealized inferential justification, I have defended (1995, 2004, 2006) the view that to be justified in believing P on the basis of E one needs to be not only justified in believing E, but justified in believing that E makes probable P (where entailment is the upper limit of making probable). And again, critics have argued that such a strong requirement fails to learn the lesson that Achilles should have been taught by the Tortoise. Even more generally, one might well argue that strong access internalists will need to deal with a variation of Carroll's puzzle even for their accounts of non-inferential justification. In this paper I'll examine these controversies with a mind to reaching a conclusion about just exactly how one can accept intellectually demanding conditions on justified belief without encountering vicious regress.

Epistemological Disjunctivism (ED) is the view that rational support for paradigm cases of perceptual knowledge that P comes from seeing that P – a state that is both factive and reflectively accessible. ED has the consequence that if I see that there is a barn before me, I can thereby be in a position to know that I am not in fake barn country. It is argued that this is a problem. The problem is distinct from familiar complaints about Neo-Mooreanism and easy knowledge. Potential ways of avoiding this problem are proposed. It is argued that they do not succeed. There is a way out of ED's fake barn problem but many will likely find it inhospitable.

Richard Fumerton has provided two possible responses that the internalist might make to the “Tortoise problem.” I argue that the second of these two responses is preferable, and I suggest one way that it might be strengthened.

In his 2010 paper “Philosophical Naturalism and Intuitional Methodology”, Alvin I. Goldman invokes the Condorcet Jury Theorem in order to defend the reliability of intuitions. The present note argues that the original conditions of the theorem are all unrealistic when analysed in connection to the case of intuitions. Alternative conditions are discussed.

The notion of a reason often plays a central role in epistemological theories. Justification is often explained in terms of the having of appropriate reasons, and a variety of epistemological distinctions are most naturally explained, it seems, by adverting to reasons. This paper examines the extent to which we may, instead, make do without appeal to such a notion. It is argued that the extent to which the notion of a reason should play an important role in epistemological theorizing will depend on how our psychological theories of belief acquisition and belief change are best conceptualized.

Hilary Kornblith explores the prospects for reasons eliminationism, the view that reasons ought not to be regarded as being of central importance in epistemology. I reply by conceding that reasons may not be necessary for knowledge, in at least some cases, but I argue that they are nevertheless vitally important in epistemology more broadly. Their importance stems from being necessary, not for knowledge but for us, given that we are social agents with practical concerns. In that sense, we have (social and practical) reasons for (having a practice of giving and receiving epistemic) reasons.

Unlike animal knowledge, mature human knowledge is not a natural phenomenon. This claim is defended by examining the concept of such knowledge and showing that it is best analysed in deontic terms. To be knowledgeable is to possess epistemic authority. Such authority is assessable in two dimensions. The first is contextually appropriate truth-reliability. The second is epistemic responsibility in three senses of “responsibility”: accountability, due diligence and liability to sanction. The fact that knowledge can be impugned by non-culpable unreliability shows that, with respect to loss of authority, liability is strict. This entails that mature human knowledge requires some degree of epistemic self-consciousness: in particular, the conceptual capacities for critically examining one's beliefs. Arguments advanced by Kornblith for the claim that there is a vicious regress involved in this requirement are shown to depend on under-described examples. When the examples are fleshed out, we see that the “critical reflection” requirement does not demand constant self-monitoring but only the capacity to recognize and respond to appropriate epistemic queries. Recognizing that the practice of justifying one's beliefs conforms to a default and query structure also dispels the illusion that insisting that epistemic subjects have some sense of their own epistemic powers involves an unpalatable form of epistemic circularity.

In Michael Williams' “What's So Special About Human knowledge?” he argues that the kind of knowledge characteristic of adult humans is distinctive in that it involves epistemic responsibility. In particular, when an adult human has knowledge, they have a certain kind of epistemic authority, and that to attribute knowledge to them is to grant them a certain kind of authority over the subject matter. I argue that, while it is true that when we attribute knowledge to adult humans, we typically also attribute to them the relevant kind of epistemic authority, this need not be because adult humans have a distinctive kind of knowledge. Rather, it may be because adult humans are distinctive kinds of beings - beings that can have epistemic authority over the subject matter about which they know. The only thing that need be special about human knowledge is that it's had by human knowers.

To solve the problem of induction we had first better know what it is. Some ways of formulating the worry about induction are underwhelming as they depend on assumptions that don't survive much scrutiny. Perhaps the most disturbing argument for inductive skepticism appeals to the claim that we could not possibly be justified in taking our inductive methods to be reliable independently of our use of those methods. And the use of inductive methods cannot give us justification to suppose that they are reliable. I argue for a new way to escape the first horn of this dilemma.
