In this paper we propose to argue for two claims. The first is that a sizeable group of epistemological projects – a group which includes much of what has been done in epistemology in the analytic tradition – would be seriously undermined if one or more of a cluster of empirical hypotheses about epistemic intuitions turns out to be true. The basis for this claim will be set out in Section 2. The second claim is that, while the jury is (...) still out, there is now a substantial body of evidence suggesting that some of those empirical hypotheses are true. Much of this evidence derives from an ongoing series of experimental studies of epistemic intuitions that we have been conducting. A preliminary report on these studies will be presented in Section 3. In light of these studies, we think it is incumbent on those who pursue the epistemological projects in question to either explain why the truth of the hypotheses does not undermine their projects, or to say why, in light of the evidence we will present, they nonetheless assume that the hypotheses are false. In Section 4, which is devoted to Objections and Replies, we’ll consider some of the ways in which defenders of the projects we are criticizing might reply to our challenge. Our goal, in all of this, is not to offer a conclusive argument demonstrating that the epistemological projects we will be criticizing are untenable. Rather, our aim is to shift the burden of argument. (shrink)

Internalists and externalists in epistemology continue to disagree about how best to understand epistemic concepts such as justification or warrant or knowledge. But there has been some movement towards agreement. Two of the most prominent rationales for the internalist position have been subjected to severe criticism by externalists: the idea that justification should be understood deontologically and the thought that justification consists in having a reason in the form of another belief. It would not be accurate to say that all (...) internalists have responded to such criticism by distancing themselves from these rationales for their position. Nevertheless some have. But despite the growing disenchantment with these two motivations for internalism, internalists continue to find the externalist position extremely unattractive. One main reason for this persistent resistance to externalism is a third rationale that is, perhaps, the most influential of the driving forces behind internalism. (shrink)

This paper is a response to Peter Klein's "Human Knowledge and the Infinite Progress of Reasoning". After briefly discussing what Klein says about the requirement, for doxastic justification, that a belief be formed in the right way, I'll make the following three points: Klein's solution to the regress problem isn't an infinitist solution, Klein's position on doxastic justification faces a troubling dilemma, and Klein's objection to foundationalism fails.

I present a puzzle about belief and credence, which takes the form of three independently supported views that are mutually inconsistent. The first is the view that S has a modal belief that p (e.g., S believes that probably-p) if and only if S has a corresponding credence that p. The second is the view that S believes that p only if S has some credence that p. The third is the view that, possibly, S believes that p without a (...) modal belief that p. [Word Count: 85].

As I head home from work, I’m not sure whether my daughter’s new bike is green, and I’m also not sure whether I’m on drugs that distort my color perception. One thing that I am sure about is that my attitudes towards those possibilities are evidentially independent of one another, in the sense that changing my confidence in one shouldn’t affect my confidence in the other. When I get home and see the bike it looks green, so I increase my (...) confidence that it is green. But something else has changed: now an increase in my confidence that I’m on color-drugs would undermine my confidence that the bike is green. Jonathan Weisberg and Jim Pryor argue that the preceding story is problematic for standard Bayesian accounts of perceptual learning. Due to the ‘rigidity’ of Conditionalization, a negative probabilistic correlation between two propositions cannot be introduced by updating on one of them. Hence if my beliefs about my own color-sobriety start out independent of my beliefs about the color of the bike, then they must remain independent after I have my perceptual experience and update accordingly. Weisberg takes this to be a reason to reject Conditionalization. I argue that this conclusion is too pessimistic: Conditionalization is only part of the Bayesian story of perceptual learning, and the other part needn’t preserve independence. Hence Bayesian accounts of perceptual learning are perfectly consistent with potential underminers for perceptual beliefs. (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)

This paper presents the theory of epistemic safety in relation to three problems: similarity, closure, and generality. Within the neo-Moorean framework of skepticism, the epistemic safety theory complements contextualist theories, where a difference is established between sceptical-thought and everyday contexts. In this way, it is claimed that conviction–i.e., when the bases upon which a belief is constructed remain unquestioned–is an intellectual virtue that makes trustworthy processes in near worlds possible. Finally, the aim of the paper is to highlight the modal (...) difference between beliefs that presuppose near worlds as their core and those that take nearby words as their core. (shrink)

This paper explains what it is to believe something for a reason. My thesis is that you believe something for a reason just in case the reason non-deviantly causes your belief. In the course of arguing for my thesis, I present a new argument that reasons are causes, and offer an informative account of causal non-deviance.

In the fifth of his John Locke Lectures, Robert Brandom takes up the challenge to define a formal semantics for modelling conceptual contents according to his normative analysis of linguistic practices. The project is to exploit the notion of incompatibility in order to directly define a modally robust relation of entailment. Unfortunately, it can be proved that, in the original definition, the modal system represented by Incompatibility Semantics (IS) collapses into propositional calculus. In this paper I show how IS can (...) be technically amended so to overcome this failure: the required modifications are already known and consist in adapting and including the main notions of Kripke's standard framework of possible worlds. I also show that the modifications do not jeopardize Brandom's original project. (shrink)

According to epistemological internalism, the rationality of a belief supervenes purely on "internal facts" about the thinker's mind. But what are "internal facts"? Why does the rationality of a belief supervene on them? The standard answers are unacceptable. This paper proposes new answers. "Internal facts" are facts about the thinker's nonfactive mental states. The rationality of a belief supervenes on such internal facts because we need rules of belief revision that we can follow directly, not by means of following any (...) other rules, and the proximate explanation of any belief revision always consists of such internal facts.

The purpose of this paper is to consider Joshua Gert’s novel view of subjective practical rationality in his book Brute Rationality. After briefly outlining the account, I present two objections to his view and then consider his own objections to a rival approach to understanding subjective rationality which I take to be much more plausible.

This paper examines the concept of coherence and its role in legal reasoning. First, it identifies some problem areas confronting coherence theories of legal reasoning about both disputed questions of fact and disputed questions of law. Second, with a view to solving these problems, it proposes a coherence model of legal reasoning. The main tenet of this coherence model is that a belief about the law and the facts under dispute is justified if it is “optimally coherent,” that is, if (...) it is such that an epistemically responsible legal decision-maker would have accepted it as justified by virtue of its coherence in like circumstances. Last, looking beyond the coherence theory, the paper explores the implications of the version of legal coherentism proposed for a general theory of legal reasoning and rationality. (shrink)

Peut-on être blâmé pour ses croyances? Bien qu’il s’agisse d’une pratique courante et en apparence légitime, le blâme doxastique entre en conflit avec deux thèses intuitivement plausibles. D’un côté, il semble que nous puissions seulement être blâmés pour ce qui est sous notre contrôle volontaire. Mais de l’autre, il est largement admis que la croyance est un état fondamentalement passif et involontaire. Il s’ensuit que nous ne pouvons jamais être blâmés pour nos croyances. Le présent article examine la réponse que (...) propose Christoph Jäger à cet argument. Sa stratégie consiste à invoquer le rejet, par Harry Frankfurt, du principe des possibilités alternatives contre la thèse voulant que nous puissions seulement être blâmés pour nos croyances si elles sont sous notre contrôle volontaire. J’aimerais montrer que l’argument de Jäger n’est pas concluant et, plus généralement, que la stratégie qu’il adopte aboutit inévitablement à un dilemme. (shrink)

As teorias epistemológicas do rastreamento sustentam que o conhecimento é uma relação real entre o agente cognitivo e seu ambiente. Os estados cognitivos de um agente epistêmico fazem o rastreamento da verdade das proposições que são objeto de conhecimento ao embasarem a crença em indicadores confiáveis da verdade (evidência, razões, ou métodos de formação de crença). A novidade nessa abordagem é que se dá pouca ênfase no tipo de justificação epistêmica voltada ao fornecimento de procedimentos de decisão doxástica ou regras (...) de responsabilidade epistêmica. Este artigo oferece um pouco da história das teorias de rastreamento e, então, defende-as contra muitas objeções que se pretendem (equivocadamente) refutadoras dessas teorias. PALAVRAS – CHAVE – Teorias de rastreamento. Nozick. Dretske. Conhecimento. ABSTRACT Tracking theories of knowledge maintain that knowledge is a real relation between cognitive agent and environment. Cognitive states of a knower track the truth of known propositions by basing belief on reliable indicators of truth (evidence, reasons, or belief forming methods). The novelty of this approach is that it places little emphasis on epistemic justification of a kind that aims at guiding epistemic agents by giving doxastic decision procedures or rules of epistemic responsibility. This paper gives some of the history of tracking theories, and then defends them against many of the objections most often judged (mistakenly) to refute tracking theories.

Evidentialism says that a subject S’s justification is entirely determined by S’s evidence. The plausibility of evidentialism depends on what kind of entities constitute a subject S’s evidence and what one takes the support relation to consist in. Conee and Feldman’s mainstream evidentialism incorporates a psychologist answer to and an explanationist answer to. ME naturally accommodates perceptual justification. However, it does not accommodate intuitive cases of inferential justification. In the second part of the paper, I consider and reject a reply (...) based on a refined explanationist theory of the support relation proposed by K McCain. (shrink)

I present and defend a reliabilist explanation of a priori knowledge which fulfils seven plausibility requirements.

The paper proposes two principles of coherence (thus taking up work started in Spohn (1991) "A Reason for Explanation: Explanations Provide Stable Reasons"). The latter indeed serves as a weak, but precise explication of the notion of coherence as it is used in the current epistemological discussion. After discussing their epistemological setting, the paper considers four ways of establishing these principles. They may be inferred neither from enumerative induction, nor from the nature of propositions as objects of belief, nor in (...) a Kantian way from self-consciousness. Rather, I propose a fairly rigorous way to infer them from an even more fundamental rationality principle of non-dogmatism and an elementary theory of perception. (shrink)

A popular counterexample directed against externalist epistemological views is that of an agent (Lehrer's "Truetemp" for example) whose beliefs are clearly neither justified nor known but that were generated in the manner that the externalist requires, thereby demonstrating externalism to be insufficient. In this essay I develop and defend an externalist account of knowledge – essentially an elaboration of Fred Dreske's information-theoretic account – that is not susceptible to those criticisms. I then briefly discuss the relationship between knowledge and justification.
