Nearly everyone agrees that perception gives us justification and knowledge, and a great number of epistemologists endorse a particular two-part view about how this happens. The view is that perceptual beliefs get their justification from perceptual experiences, and that they do so by being based on them. Despite the ubiquity of these two views, I think that neither has very much going for it; on the contrary, there’s good reason not to believe either one of them.

Some recent work in formal epistemology shows that “witness agreement” by itself implies neither an increase in the probability of truth nor a high probability of truth—the witnesses need to have some “individual credibility.” It can seem that, from this formal epistemological result, it follows that coherentist justification (i.e., doxastic coherence) is not truth-conducive. I argue that this does not follow. Central to my argument is the thesis that, though coherentists deny that there can be noninferential justification, coherentists do not (...) deny that there can be individual credibility. (shrink)

I argue that coherence is truth-conducive in that coherence implies an increase in the probability of truth. Central to my argument is a certain principle for transitivity in probabilistic support. I then address a question concerning the truth-conduciveness of coherence as it relates to (something else I argue for) the truth-conduciveness of consistency, and consider how the truth-conduciveness of coherence bears on coherentist theories of justification.

Andrew Cling presents a new version of the epistemic regress problem, and argues that intuitionist foundationalism, social contextualism, holistic coherentism, and infinitism fail to solve it. Cling’s discussion is quite instructive, and deserving of careful consideration. But, I argue, Cling’s discussion is not in all respects decisive. I argue that Cling’s dilemma argument against holistic coherentism fails.

Does the scope of beliefs that people can form on the basis of perception remain fixed, or can it be amplified with learning? The answer to this question is important for our understanding of why and when we ought to trust experts, and also for assessing the plausibility of epistemic foundationalism. The empirical study of perceptual expertise suggests that experts can indeed enrich their perceptual experiences through learning. Yet this does not settle the epistemic status of their beliefs. One might (...) hold that the background knowledge of experts is the cause of their enriched perceptual experience – what is known as cognitive permeation – and so their subsequent beliefs are only mediately justified because they are epistemically dependent on this background knowledge. I argue against this view. Perceptual expertise is not the result of cognitive permeation but is rather the result of perceptual learning, and perceptual learning does not involve cognition in a way that entails cognitive permeation. Perceptual expertise thus provides a means of widening the scope of the immediately justified beliefs that experts can form. (shrink)

This article develops a theory of reasons that has strong similarities to Peter Klein's infinitism. The view it develops, Framework Reasons, upholds Klein's principles of avoiding arbitrariness (PAA) and avoiding circularity (PAC) without requiring an infinite regress of reasons. A view of reasons that holds that the “reason for” relation is constrained by PAA and that PAC can avoid an infinite regress if the “reason for” relation is contextual. Moreover, such a view of reasons can maintain that skepticism is false (...) by the maintaining that there is more to epistemic justification than can be expressed in any reasoning session. One crucial argument for Framework Reasons is that justification depends on a background of plausibility considerations. The final section of the article applies this view of reasons to Michael Bergmann's argument that any nonskeptical epistemology must embrace epistemic circularity. (shrink)

This paper develops and defends a coherentist account of reasons. I develop three core ideas for this defense: a distinction between basic reasons and noninferential justification, the plausibility of the neglected argument against first philosophy, and an emergent account of reasons. These three ideas form the backbone for a credible coherentist view of reasons. I work toward this account by formulating and explaining the basic reasons dilemma. This dilemma reveals a wavering attitude that coherentists have had toward basic reasons. More (...) importantly, the basic reasons dilemma focuses our attention on the central problems that afflict coherentist views of basic beliefs. By reflecting on the basic reasons dilemma, I formulate three desiderata that any viable coherentist account of basic beliefs must satisfy. I argue that the account on offer satisfies these desiderata. (shrink)

This paper argues that the crossword puzzle analogy is great for scientific rationality, but not scientific warrant. It provides a critical analysis of foundherentist conceptions of scientific warrant, especially that of Susan Haack, and closely related positions, such as non-doxastic coherentism. Foundherentism takes the middle ground between foundationalism and coherentism. The main idea is that warrant, including that of scientific theories, is like warrant of crossword entries: the degree to which a theory is warranted depends on one’s observations, the extent (...) to which it coheres with one’s other scientific theories and whether one’s evidence includes a sufficiently large portion of the relevant evidence. I identify three problems for a foundherentist conception of scientific warrant, two of which are also problems for the image of science as a crossword puzzle. First, Haack’s conceptions of personal and social warrant of scientific theories are incompatible. Second, the notion of warrant defe.. (shrink)

There is a long-Standing tradition in philosophy that certain metaphysical theories of perceptual experience, if true, would lead to scepticism about the external world, whereas other theories, if true, would develop a non-sceptkal epistemology. I investigate these claims in the context of current metaphysical theories of sense-perception and argue that choice of perceptual ontology is of very limited help in developing a non-sceptical epistemology. Theorists who hold that perception is an intentional state have some advantage in explaining how perceptual experiences (...) serve as justifying reasons for empirical beliefs. Alston and others have argued that a successful defence of a contemporary version of naïve realism would secure further epistemological advantages. I argue that this is not the case. A complete explanation of experience's reason-giving power involves factors beyond the metaphysical nature of experience. (shrink)

Phenomenal conservatism as developed by some philosophers faces a previously unnoticed problem. The problem stems from the fact that, as some develop the view, phenomenal conservatism holds that seemings alone justify—sensations have no justificatory impact. Given this, phenomenal conservatism faces a problem analogous to the isolation objection to coherentism. As foundationalists, supporters of phenomenal conservatism will want to allow that the isolation objection is effective against coherentism, and yet claim that a similar objection is not effective against their view. Unfortunately, (...) it appears that on most understandings of the nature of seemings phenomenal conservatism can only avoid its version of the isolation objection by sacrificing its internalist character.

Cognitive penetration of perception is the idea that what we see is influenced by such states as beliefs, expectations, and so on. A perceptual belief that results from cognitive penetration may be less justified than a nonpenetrated one. Inferentialism is a kind of internalist view that tries to account for this by claiming that some experiences are epistemically evaluable, on the basis of why the perceiver has that experience, and the familiar canons of good inference provide the appropriate standards by (...) which experiences are evaluated. I examine recent defenses of inferentialism by Susanna Siegel, Peter Markie, and Matthew McGrath and argue that the prospects for inferentialism are dim. (shrink)

An explanatory coherence theory of justification is sketched and then defended against a number of recent objections: conservatism and relativism; wild and crazy beliefs; reliability; warranted necessary falsehoods; basing; distant, unknown coherences; Sosa's “self- and present-abstracts”; and Bayesian impossibility results.

I think it is important to try to make sense of these thoughts concerning the justificatory role of experiences, for I suspect that we are losing the ability to see why philosophers have traditionally been attracted to such thoughts. Coherentism and reliabilism, perhaps the two most currently popular theories of epistemic justification, appear simply to reject the idea that experiences can justify beliefs. Thus according to coherentism, the view that ‘a belief is justified by its coherence with other beliefs one (...) holds,’ it is only other beliefs, not experiences, that can justify beliefs. Although there is little consensus as to how the notion of coherence should be explicated, it is generally agreed that experiences are not the sort of thing that can cohere with beliefs. Reliabilism, by contrast, holds that ‘a belief is justified if and only if it is “well-formed,” i.e., it has an ancestry of reliable and/or conditionally reliable cognitive operations.’ In other words, according to reliabilism beliefs are justified, not by experiences, but by being caused by reliable belief-forming processes. Experiences may be formed in the course of such processes, but they need not be, and even when they are, they make no contribution to the justification of the beliefs that are formed as the result of those processes. What makes a belief-forming process justification-conferring, according to reliabilism, is simply that it is reliable, not that it gives rise to experiences. So neither coherentism nor reliabilism seems to allow any room for the traditional thought that experiences justify beliefs. (shrink)

A belief must have justification if it is to count as knowledge. And it is a commonplace thought that in certain circumstances experiences can serve as justifications for beliefs. Moreover, many have thought that there is something distinctive about the wayin which experiences justify beliefs, and that there is something distinctive about experiences which accounts for the distinctive way in which they justify beliefs. In this paper, I seek to elucidate views about experience and justification that can make sense of (...) these thoughts and that can show us why so many have been attracted to them.I think it is important to try to make sense of these thoughts concerning the justificatory role of experiences, for I suspect that we are losing the ability to see why philosophers have traditionally been attracted to such thoughts.

The most pressing difficulty coherentism faces is, I believe, the problem of justified inconsistent beliefs. In a nutshell, there are cases in which our beliefs appear to be both fully rational and justified, and yet the contents of the beliefs are inconsistent, often knowingly so. This fact contradicts the seemingly obvious idea that a minimal requirement for coherence is logical consistency. Here, I present a solution to one version of this problem.

A foundationalist account of our empirical thinking divides propositions we accept into two classes, basic and derivative, and sees the warrant of derivative propositions as accruing to them through their derivation from basic propositions. Such an account needs to answer two questions: which propositions are basic, and whence do basic propositions acquire their warrant? A natural and ancient answer to these questions is that basic propositions are observational and that these propositions gain their warrant from perceptions. I critically examine this (...) view and also a variant view offered by Wilfrid Sellars. I put forward an alternative conception, dialectical foundationalism, that sees the distinction between the basic and the derivative as issuing from a distinction between two kinds of reasoning, derivational and dialectical. This type of foundationalism provides a more accurate account of our empirical thinking, I argue, than its traditional and Sellarsian counterparts. (shrink)

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

Once upon a time, coherentism was the dominant response to the regress problem in epistemology, but in recent decades the view has fallen into disrepute: now almost everyone is a foundationalist (with a few infinitists sprinkled here and there). In this paper, I sketch a new way of thinking about coherentism, and show how it avoids many of the problems often thought fatal for the view, including the isolation objection, worries over circularity, and concerns that the concept of coherence is (...) too vague or metaphorical for serious theoretical use. The key to my approach is to take a familiar tool from discussions of the regress problem -- namely, directed graphs depicting the support relations between beliefs -- and to use that tool in a more sophisticated manner than it is standardly employed.
