In what follows, I discuss the extent to which the epistemology of religious belief differs from the epistemology of other areas of our belief, as well as the extent to which it is similar. There will be important similarities: for example, the standards for the application of terms of epistemic assessment like ‘justified’, ‘warranted’,and ‘rational’. But in this essay, I concentrate on delineating some important differences between religious and non-religious epistemology.

In this paper I discuss two claims; the first is the claim that state-given reasons for belief are of a radically different kind to object-given reasons for belief. The second is that, where this last claim is true, epistemic reasons are object-given reasons for belief (EOG). I argue that EOG has two implausible consequences: (i) that suspension of judgement can never be epistemically justified, and (ii) that the reason that epistemically justifies a belief that p can never be the reason (...) for which one believes that p.

In this paper I consider whether there can be such things as epistemic reasons for action. I consider three arguments to the contrary and argue that none are successful, being either somewhat question-begging or too strong by ruling out what most epistemologists think is a necessary feature of epistemic justification, namely the epistemic basing relation. I end by suggesting a "non-cognitivist" model of epistemic reasons that makes room for there being epistemic reasons for action and suggest that this model may (...) support moral realism. (shrink)

According to reliabilists about epistemic justification, what makes a belief epistemically justified is that it was produced by a reliable process of belief-formation. Earl Conee and Richard Feldman have forcefully presented a problem for such reliabilism, "the generality problem."? The generality problem arises once we realize that the notion of reliability applies straightforwardly only to types of process--for only types of process are repeatable entities which can produce true or false beliefs in each of their instances. Moreover, any token process (...) will be an instance of indefinitely many types of process. Which of these types must be reliable for my belief to be justified, according to reliabilism? That question, generalized to cover every case of belief-formation, is the generality problem for reliabilism. In this paper I propose a solution to the generality problem. The solution makes use of the basing relation, and so, given that it isn't clear how to characterize that relation, it might be thought to replace one problem with another. I argue that, however difficult it is to characterize the basing relation, every adequate epistemological theory must make use of it implicitly or explicitly. Therefore, it is perfectly legitimate to appeal to the basing relation in solving a problem for an epistemological theory. (shrink)

Moral and legal judgments sometimes depend on personal traits in this sense: the subject offers good reasons for her judgment, but if she had a different social or ideological background, her judgment would be different. If you would judge the constitutionality of restrictions on abortion differently if you were not a secular liberal, is your judgment really based on the arguments you find convincing, or do you find them so only because you are a secular liberal? I argue that a (...) judgment can be based on the considerations the subject claims as justification even when it depends on personal traits. (shrink)

Some critics of coherentism have depicted it so that it founders on the distinction between warrant for the content of a belief and warrant for the believing itself. This distinction has to do with the basing relation: one might have warrant for the content of what one believes without basing one's belief properly, without holding the belief because of what warrants it. When the first kind of warrant obtains, I will say that a belief is propositionally warranted.

LEMKE has recently taken issue (see ANALYSIS 46.3, June 1986, pp. 138-44) with my claim that no counterfactual causal account of the basing relation is plausible (see ANALYSIS 45.3, June 1985, pp. 153-8). Intuitively, a counterfactual causal account claims that belief is based on evidence if and only if the evidence either causes the belief or would have caused it had the actual cause been absent. This intuitive formulation accounts only for counterfactual causes of level one: events which would have (...) been a cause had only the actual cause been absent. As I argued, there is as much support for allowing counterfactual causes having a higher cardinality: events which would have been a cause had the actual cause and some other counterfactual causes been absent.

Suppose we want to know whether a person justifiably believes a certain claim. Further, suppose that our interest in this question is because we take such justification to be necessary for knowledge. To justifiably believe a claim requires more than there being a justification for that claim. Presumably, there is a justification for accepting all sorts of scientific theories of which I have no awareness; because of my lack of awareness, I do not justifiably believe those theories. Further, even if (...) I, by chance, did believe one of those theories, I might not justifiably believe it; for I may be completely unaware of any justification for it. I then would not believe it.. (shrink)

According to a common view, the activity of justifying is epistemologically irrelevant: being justified in believing as one does never requires the ability to justify one’s belief. This view runs into trouble regarding the epistemic basing relation, the relation between a person’s belief and the reasons for which the person holds it. The view must appeal to basing relations as part of its account of what it is for a person to be justified in believing as she does, but the (...) view prevents basing relations from doing the needed work. In place of the common view, I propose an account of basing relations which links them to the person’s commitments and hence to her justificatory activity. If this proposal is correct, then positive justificatory status, too, will be conceptually linked to the ability to succeed in the activity of justifying. (shrink)

We commonly speak of people as being ‘‘justified’’ or ‘‘unjustified’’ in believing as they do. These terms describe a person’s epistemic condition. To be justified in believing as one does is to have a positive epistemic status in virtue of holding one’s belief in a way which fully satisfies the relevant epistemic requirements or norms. This requires something more (or other) than simply believing a proposition whose truth is well-supported by evidence, even by evidence which one possesses oneself, since one (...) could entirely miss the relevance of this evidence and hold the belief as a result of wishful thinking or for some other bad reason. My topic in this paper is the notion of being justified which precludes beliefs flawed in this way. I will take the notion of something’s telling in favor of the truth of a proposition—that is, the notion of evidential support—for granted. (shrink)

It is commonplace to distinguish between propositional justification (having good reasons for believing p) and doxastic justification (believing p on the basis of those good reasons).One necessary requirement for bridging the gap between S’s merely having propositional justification that p and S’s having doxastic justification that p is that S base her belief that p on her reasons (propositional justification).A plausible suggestion for what it takes for S’s belief to be based on her reasons is that her reasons must contribute (...) causally to S’s having that belief. Though this suggestion is plausible, causal accounts of the basing relation that have been proposed have not fared well. In particular, cases involving causal deviancy and cases involving over-determination have posed serious problems for causal accounts of the basing relation. Although previous causal accounts of the basing relation seem to fall before these problems, it is possible to construct an acceptable causal account of the basing relation. That is, it is possible to construct a causal account of the basing relation that not only fits our intuitions about doxastic justification in general, but also is not susceptible to the problems posed by causal deviancy and causal over-determination. The interventionist account of causation provides the tools for constructing such an account. My aim is to make use of the insights of the interventionist account of causation to develop and defend an adequate causal account of the basing relation. (shrink)

What knowledge is imperilled by sceptical doubt? That is, what range of beliefs may be called into doubt by sceptical nightmares like the Cartesian demon hypothesis? It is generally thought that demons have limited powers, perhaps only threatening a posteriori knowledge of the external world, but at any rate not threatening principles like the cogito. I will argue that there is a demon – the debasing demon – with unlimited powers, which threatens universal doubt. Rather than deceiving us with falsities, (...) the debasing demon would allow us true beliefs, but only as guesses. (shrink)

Some time ago, F. P. Ramsey (1960) suggested that knowledge is true belief obtained by a reliable process. This suggestion has only recently begun to attract serious attention. In 'Discrimination and Perceptual Knowledge', Alvin Goldman (1976) argues that a person has knowl- edge only if that person's belief has been formed as a result of a reliable cognitive mechanism. In Belief, Truth, and Knowledge, David Arm- strong (1973) argues that one has knowledge only if one's belief is a comPletely reliable (...) sign of the truth of the proposition believed. On both of these theories, the reliability of one's belief is a necessary condition of that belief's being an instance of knowledge. These reliability theories have another interesting feature in common, namely, that neither of them explicitly requires or includes the traditional justification requirement for knowledge. Reliability has taken over the role of justification. This naturally leads to the question whether reliability and justification are related in some philosophically interes- ting fashion. In this paper I shall investigate this question. The result will be a positive proposal to the effect that justified belief is reliable belief. This result, in turn, explains why reliability can take over the role of justification in an account of knowledge. Moreover, the identification of justification with reliability constitutes a step toward the naturalization of normative epistemological concepts. (shrink)

In this paper, we review Keith Lehrer’s account of the basing relation, with particular attention to the two cases he offered in support of his theory, Raco (Lehrer, Theory of knowledge, 1990; Theory of knowledge, (2nd ed.), 2000) and the earlier case of the superstitious lawyer (Lehrer, The Journal of Philosophy, 68, 311–313, 1971). We show that Lehrer’s examples succeed in making his case that beliefs need not be based on the evidence, in order to be justified. These cases show (...) that it is the justification (rather than the belief) that must be based in the evidence. We compare Lehrer’s account of basing with some alternative accounts that have been offered, and show why Lehrer’s own account is more plausible. (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.

I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason(s) R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

What exactly is reasoning? Like many other philosophers, I shall endorse a broadly causal conception of reasoning. Reasoning is a causal process, in which one mental event (say, one’s accepting the conclusion of a certain argument) is caused by an antecedent mental event (say, one’s considering the premises of the argument). Just like causal accounts of action and causal accounts of perception, causal accounts of reasoning have to confront a version of what has come to be known as the problem (...) of deviant causal chains. In this paper, I shall propose an account of the nature of reasoning, incorporating a solution to the specific version of the deviant causal chains problem that arises for accounts of reasoning. One striking feature of my solution is that it requires that certain normative facts are causally efficacious. It might be thought that this feature will make my account incompatible with any plausibly naturalistic approach to understanding the mind. I shall argue that this is not so: my account of the nature of reasoning is quite compatible with plausible versions of naturalism. (shrink)

It has been a commonplace from the beginnings of philosophical thought that what distinguishes humans from other species is the ability to reason; reason- ing is held to be an essential characteristic of the species and one that is unique to it. The essence condition requires that all humans possess at least the capacity for reasoning and that it be exercised in many of the ordinary cases of acquiring beliefs. And uniqueness entails that non-humans cannot reason, no matter how much (...) their behavior resembles that of humans. I think that a certain specific model of reasoning has been presupposed by proponents of these claims. And there are grounds to believe that this model is inaccurate in essential respects: if reasoning does correspond to it, then few human beliefs are acquired through reason. However, given a more accurate description of what goes on in normal human reasoning, it is no longer plausible to think that only humans reason. So either the essence or the uniqueness claim must be given up. In this paper I argue for the second option. (shrink)

§1 It is not always true that recognizably valid reasoning from known, or otherwise epistemically warranted premises, can be enlisted to produce knowledge, or other epistemic warrant, for a conclusion. The counterexamples are cases that exhibit what I have elsewhere called warrant transmission-failure. It is nowadays widely accepted that there are indeed such counterexamples, though individual cases remain controversial. One such controversial case is the so-called McKinsey paradox. The paradox presents as a simple collision between three claims that many would (...) find attractive. (shrink)

This paper argues that higher-order doubt generates an epistemic dilemma. One has a higher-order doubt with regards to P insofar as one justifiably withholds belief as to what attitude towards P is justified. That is, one justifiably withholds belief as to whether one is justified in believing, disbelieving, or withholding belief in P. Using the resources provided by Richard Feldman’s recent discussion of how to respect one’s evidence, I argue that if one has a higher-order doubt with regards to P, (...) then one is not justified in having any attitude towards P. Otherwise put, no attitude towards the doubted proposition respects one’s higher-order doubt. I argue that the most promising response to this problem is to hold that when one has a higher-order doubt about P, the best one can do to respect such a doubt is to simply have no attitude towards P. Higherorder doubt is thus much more rationally corrosive than non-higher-order doubt as it undermines the possibility of justifiably having any attitude towards the doubted proposition. (shrink)

This paper is an examination of modest foundationalism in relation to some important criteria of epistemic dependence. The paper distinguishes between causal and epistemic dependence and indicates how each might be related to reasons. Four kinds of reasons are also distinguished: reasons to believe, reasons one has for believing, reasons for which one believes, and reasons why one believes. In the light of all these distinctions, epistemic dependence is contrasted with defeasibility, and it is argued that modest foundationalism is not (...) committed to criteria of epistemic dependence on which foundational beliefs are indefeasible. Modest foundationalism is contrasted with coherentism and is shown to be hospitable to a causal criterion of epistemic dependence, compatible with reliabilism, and neutral with respect to skepticism.

Here I present and defend an etiological theory of objective, doxastic justification, and related theories of defeat and evidence. The theory is intended to solve a problem for reliabilist epistemologies—the problem of identifying relevant environments for assessing a process’s reliability. It is also intended to go some way to accommodating, neutralizing, or explaining away many internalist-friendly elements in our epistemic thinking.

In this, the first book to address the ongoing debate, Plantinga presents his influential thesis and responds to critiques by distinguished philosophers from a ...

According to Keith Lehrer’s coherence theory, knowledge is true acceptance whose justification is undefeated by a falsehood. It has recently become clear that Lehrer’s handling of important Gettier-inspired problems depends upon his position that only falsehoods accepted by the subject can act as defeaters of knowledge. I argue against this and present an example in which an unreckoned truth---one neither believed nor believed to be false by the subject---defeats knowledge. I trace the negative implications of this matter for the coherence (...) theory. (shrink)

Internalists tend to impose on justification higher-level requirements, according to which a belief is justified only if the subject has a higher-level belief (i.e., a belief about the epistemic credentials of a belief). I offer an error theory that explains the appeal of this requirement: analytically, a belief is not justified if we have a defeater for it, but contingently, it is often the case that to avoid having defeaters, our beliefs must satisfy a higher-level requirement. I respond to the (...) objection that externalists who endorse this error theory will be forced to accept a radical form of scepticism. (shrink)

It is currently fashionable to hold that deontology induces internalism. That is, those who think that epistemic justification is essentially a matter of duty fulfillment are thought to have a good reason for accepting internalism in epistemology. I shall argue that no deontological conception of epistemic justification provides a good reason for endorsing internalism. My main contention is that a requirement having to do with epistemic defeat-a requirement that many externalists impose on knowledge-guarantees the only sorts of deontological justification that (...) have a chance at inducing internalism. Given this compatibility of externalism and deontology, we may safely conclude that deontology by itself doesn't lend support to internalism. (shrink)

Despite various attempts to rectify matters, the internalism-externalism (I-E) debate in epistemology remains mired in serious confusion. I present a new account of this debate, one which fits well with entrenched views on the I-E distinction and illuminates the fundamental disagreements at the heart of the debate. Roughly speaking, the I-E debate is over whether or not certain of the necessary conditions of positive epistemic status are internal. But what is the sense of internal here? And of which conditions of (...) which positive epistemic status are we speaking? I argue that an adequate answer to these questions requires reference to what I call the no-defeater condition which is satisfied by a subjects belief B just in case she does not believe that B is defeated. I close by stating succinctly the main positions taken in the I-E debate, identifying the basic points of disagreement and suggesting fruitful courses for future discussion. (shrink)

Virtually all philosophers agree that for a belief to be epistemically justified, it must satisfy certain conditions. Perhaps it must be supported by evidence. Or perhaps it must be reliably formed. Or perhaps there are some other "good-making" features it must have. But does a belief's justification also require some sort of awareness of its good-making features? The answer to this question has been hotly contested in contemporary epistemology, creating a deep divide among its practitioners. Internalists, who tend to focus (...) on scientific or theoretical beliefs as the ideal, insist that such awareness is required for justification. Externalists, who think children's ordinary beliefs in obvious facts are paradigm cases of justified belief, say it isn't required. Michael Bergmann's book offers a decisive refutation of internalism and a sustained defense of externalism. (shrink)

It appears to have gone unnoticed in the literature that Pollock's widely endorsed analysis of evidential defeat entails a remarkably strong symmetry principle, according to which, for any three propositions D, E and H, if both E and D provide a reason to believe H, then D is a defeater for E's support for H if and only if, in turn, E is a defeater for D's support for H. After illustrating the counterintuitiveness of this constraint, a simple, more suitable, (...) alternative to the Pollockian account is offered. (shrink)

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically rational in (...) the sense that both are supported by sufficient evidence.

It is bad news to find out that one's cognitive or perceptual faculties are defective. Furthermore, it’s not always transparent how one ought to revise one's beliefs in light of such news. Two sorts of news should be distinguished. On the one hand, there is news that a faculty is unreliable -- that it doesn't track the truth particularly well. On the other hand, there is news that a faculty is anti-reliable -- that it tends to go positively wrong. These (...) two sorts of news call for extremely different responses. We provide accounts of these responses, and prove bounds on the degree to which one can reasonably count oneself as mistaken about a given subject matter. (shrink)

When it comes to evaluating our own abilities and prospects, most (non-depressed) people are subject to a distorting bias. We think that we are better – friendlier, more well-liked, better leaders, and better drivers – than we really are. Once we learn about this bias, we should ratchet down our self-evaluations to correct for it. But we don’t. That leaves us with an uncomfortable tension in our beliefs: we knowingly allow our beliefs to differ from the ones that we think (...) are supported by our evidence. We can mitigate the tension by waffling between two belief states: a reflective state that has been recalibrated to take into account our tendency to overrate ourselves, and a non-reflective state that has not.

According to the received view, externalist grounds or reasons need not be introspectively accessible. Roughly speaking, from an externalist point of view, a belief will be epistemically justified, iff it is based upon facts that make its truth objectively highly likely. This condition can be satisfied, even if the epistemic agent does not have actual or potential awareness of the justifying facts. No inner perspective on the belief-forming mechanism and its truth-ratio is needed for a belief to be justified. In (...) my view, this is not the whole story. While I agree that introspective access to our reasons is a defining feature of justification for the access internalist, not the externalist, I will argue that even for the latter, some kind of introspective access is an epistemic desideratum. Yet, even given that I am right, the desirable might not be achievable for us. Recent psychological research suggests that we do not dispose of reliable introspection into the sources of our own beliefs. This seems to undermine the claim that we can introspectively know about the reasons upon which our beliefs are based. In this paper I will therefore additionally show why these results do not threaten the kind of introspective access desirable from an externalist point of view. (shrink)

It is widely assumed that justification is defeasible, e.g. that under certain conditions counterevidence removes prior justification of beliefs. In this paper I will first (sect. 1) explain why this feature of justification poses a prima facie problem for reliabilism. I then will try out different reliabilist strategies to deal with the problem. Among them I will discuss conservative strategies (sect. 2), eliminativist stragies (sect. 3) and revisionist strategies (sect. 4). In the final section I will present an improved revisionist (...) approach to defeaters that is able to overcome the main shortcomings of the other approaches. (shrink)

I defend the view that there is a privileged class of propositions – that there is an external world, among other such 'hinge propositions'– that possess a special epistemic status: justified belief in these propositions is not defeated unless one has sufficient reason to believe their negation. Two arguments are given for this conclusion. Finally, three proposals are offered as morals of the preceding story: first, our justification for hinge propositions must be understood as defeatable, second, antiskeptics must explain our (...) knowledge in the face of 'actual world' skepticism (like dreaming skepticism) as much as in the face of the usual sort (like brain-in-vat skepticism), and, finally, our justification for hinge propositions is basic (i.e. non-inferential). (shrink)

The problem of induction and the problem of Cartesian/brain-in-the-vat skepticism have much in common. Both are instances of a general problem of defeasible justification . I use the term "defeasible justification" to refer to a relation between a piece of evidence.

Robert Almeder has argued1 that three “fourth conditions” for nondefectiveness of knowledge justification claims, proposed in the recent literature,2 are essentially similar, require modification in order to eliminate the possibility of an unknowable defeater, and, so modified, render attainment of non-basic factual knowledge impossible. Although I believe there are objections to be raised against his exposition and reduction of the three proposed fourth conditions, I wish only to raise some doubts about the supposed necessity of the modifications and then to (...) argue against his claim that, so modified, the result is too stringent. (shrink)

The purpose of this paper is to refute the widespread view that challenging a knowledge-claim always raises the original standards of justification–a view often associated with contextualism. To that purpose the distinction between undermining and overriding defeaters will be used. Three kinds of challenges will be considered that differ in their degree of specification. In all three kinds of challenges, the rising standards of justification model fails to capture the dialectic of justification in the case of undermining defeaters. At the (...) end, the skeptical challenge will more briefly be given a similar analysis. (shrink)

There are two different kinds of theories of the concept of epistemic defeat. One theory begins with propositional relationships, only by implication describing what happens in the context of a noetic system. Such a theory places inforrmation about defeat up front, not informing us of how the defeat relationships play out in the context of actual belief, at least not initially. The other theory takes a back door to the concept of defeat, assuming a context of (...) actual belief and an entire noetic system, and describing defeat in terms of what sort of doxastic and noetic responses would be appropriate to the addition of particular pieces of information. Where the house is the noetic structure itself, the front door approach characterizes the concept of defeat in terms of the propositional contents a belief might have, thus characterizing defeat at the front door. The backdoor approach characterizes defeat in terms of what leaves the house, in terms of beliefs that exit the noetic system in response to changes to it, in terms of what the staff of a well-run household kicks out the backdoor for making a mess of things. Alvin Plantinga’s theory of epistemic defeat is a back-door theory, and here I will argue that his theory and approaches like it will be unable to explicate accurately the concept of epistemic defeat. I will argue that a front door approach is needed rather than a back door approach. (shrink)

Ever since Gettier 1963 convinced English-speaking philosophers that justified true belief does not suffice for knowledge, many epistemologists have been searching for the elusive “fourth condition” of knowledge: the condition that must be added to justification, truth, and belief, in order to get a set of non-trivial conditions that are individually necessary and jointly sufficient for knowledge.1 The problem of finding such conditions is generally known as the “Gettier problem”. Many different fourth conditions have been proposed and subsequently counterexampled, and (...) some philosophers have suggested that some of the other three conditions may need to be revised as well. But recently, several philosophers have suggested that the Gettier problem is insoluble, and that the theory of knowledge should proceed in a more modest way: not by trying to specify a set of non-trivial conditions that are individually necessary and jointly sufficient for knowledge, but rather by trying to figure out whatever we can about knowledge, and in particular to figure out the role that knowledge, and knowledge ascription, play in our lives. Williamson 2000 has developed an epistemological view that falls within this latter, more modest approach to the theory of knowledge, and his work has been immediately and justly influential.

The last century has seen many disciplines place a greater priority on understanding how people reason in a particular domain, and several illuminating theories of informal logic and argumentation have been developed. Perhaps owing to their diverse backgrounds, there are several connections and overlapping ideas between the theories, which appear to have been overlooked. We focus on Peirce’s development of abductive reasoning [39], Toulmin’s argumentation layout [52], Lakatos’s theory of reasoning in mathematics [23], Pollock’s notions of counterexample [44], and argumentation (...) schemes constructed by Walton et al. [54], and explore some connections between, as well as within, the theories. For instance, we investigate Peirce’s abduction to deal with surprising situations in mathematics, represent Pollock’s examples in terms of Toulmin’s layout, discuss connections between Toulmin’s layout and Walton’s argumentation schemes, and suggest new argumentation schemes to cover the sort of reasoning that Lakatos describes, in which arguments may be accepted as faulty, but revised, rather than being accepted or rejected. We also consider how such theories may apply to reasoning in mathematics: in particular, we aim to build on ideas such as Dove’s [13], which help to show ways in which the work of Lakatos fits into the informal reasoning community.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

Plantinga examines the nature of epistemic warrant; whatever it is that when added to true belief yields knowledge. This volume surveys current contributions to the debate and paves the way for his owm positive proposal in Warrant and Proper Function.

Two notions from philosophical logic and linguistics are brought together and applied to the psychological study of defeasible conditional reasoning. The distinction between disabling conditions and alternative causes is shown to be a special case of Pollock's (1987) distinction between 'rebutting' and 'undercutting' defeaters. 'Inferential' conditionals are shown to come in two varieties, one that is sensitive to rebutters, the other to undercutters. It is thus predicted and demonstrated in two experiments that the type of inferential conditional used as the (...) major premise of conditional arguments can reverse the heretofore classic, distinctive effects of defeaters. (shrink)

The question addressed in this paper is how the degree of justification of a belief is determined. A conclusion may be supported by several different arguments, the arguments typically being defeasible, and there may also be arguments of varying strengths for defeaters for some of the supporting arguments. What is sought is a way of computing the “on sum” degree of justification of a conclusion in terms of the degrees of justification of all relevant premises and the strengths of all (...) relevant reasons.

There was a long tradition in philosophy according to which good reasoning had to be deductively valid. However, that tradition began to be questioned in the 1960’s, and is now thoroughly discredited. What caused its downfall was the recognition that many familiar kinds of reasoning are not deductively valid, but clearly confer justification on their conclusions. Here are some simple examples.

An argument is self-defeating when it contains defeaters for some of its own defeasible lines. It is shown that the obvious rules for defeat among arguments do not handle self-defeating arguments correctly. It turns out that they constitute a pervasive phenomenon that threatens to cripple defeasible reasoning, leading to almost all defeasible reasoning being defeated by unexpected interactions with self-defeating arguments. This leads to some important changes in the general theory of defeasible reasoning.

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

Dogmatism is a claim about a possible epistemic position, not about the metaphysics of what puts us in that position. So, for example, it leaves it open whether the intrinsic nature of a perceiving subject’s state is the same as that of a hallucinating subject’s state.

Can known disagreement with our epistemic peers undermine or defeat the justification our beliefs enjoy? Much of the current literature argues for one of two extreme positions on this topic, either that the justification of each person's belief is (fully) defeated by the awareness of disagreement, or that no belief is defeated by this awareness. I steer a middle course and defend a principle describing when a disagreement yields a partial defeater, which results in a loss of some, but not (...) all, of the justification of a belief. I show that the 'no defeater' view is too strong. I also offer reasons for thinking that the 'full defeater' view is similarly mistaken. (shrink)

Paul Benacerraf’s argument that mathematical realism is apparently incompatible with mathematical knowledge has been widely thought to also show that a priori knowledge in general is problematic. Although many philosophers have rejected Benacerraf’s argument because it assumes a causal theory of knowledge, some maintain that Benacerraf nevertheless put his finger on a genuine problem, even though he didn’t state the problem in its most challenging form. After diagnosing what went wrong with Benacerraf’s argument, I argue that a new, more challenging, (...) version of Benacerraf’s problem can be constructed. The new version—what I call the Defeater Version—of Benacerraf’s problem makes use of a no-defeater condition on knowledge and justification. I conclude by arguing that the best way to avoid the problem is to construct a theory of how a priori judgments reliably track the facts. I also suggest four different kinds of theories worth pursuing. (shrink)

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical indefeasibility is essential to the primary notion of the a priori; however, the indefeasibility requirement should be interpreted in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with the naturalist’s (...) commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish empiricism, so fallibilist apriorism represents a distinct position. (shrink)

In the early 1990s there emerged a growing interest with the concept of epistemic entitlement. Philosophers who acknowledge the existence of entitlements maintain that there are beliefs or judgments unsupported by evidence available to the subject, but which the subject nonetheless is justified in believing, that is, has the epistemic right to hold. Some of these may include beliefs non-inferentially sourced in perception, memory, introspection, testimony, and the a priori. Unlike the traditional notion of justification, entitlement is often characterized as (...) an externalist type of epistemic warrant, in the sense that a subject’s being entitled is determined by facts and circumstances that are independent of any reasoning capacities she may or may not have, and which the subject herself need not understand or be able to recognize. One key motivation for this view is that the inclusion of entitlement in epistemology can account for the commonly held intuition that largely unreflective individuals, such as children and non-human animals, possess warrant and basic knowledge about the world. It also paves the way for a tenable foundationalist epistemology, according to which there exist warranted beliefs which are not themselves warranted or justified by any further beliefs. This article explores theories of entitlement as presented by four prominent philosophers: Fred Dretske, Tyler Burge, Crispin Wright, and Christopher Peacocke. (shrink)

A well known skeptical paradox rests on the claim that we lack warrant to believe that we are not brains in a vat (BIVs). The argument for that claim is the apparent impossibility of any evidence or argument that we are not BIVs. Many contemporary philosophers resist this argument by insisting that we have a sort of warrant for believing that we are not BIVs that does not require having any evidence or argument. I call this view ‘New Rationalism’. I (...) argue that New Rationalists are committed to there being some evidence or argument for believing that we are not BIVs anyway. Therefore, New Rationalism, since its appeal is that it purportedly avoids the problematic commitment to such evidence or argument, undermines its own appeal. We cannot avoid the difficult work of coming up with evidence or argument by positing some permissive sort of warrant. (shrink)

The paper is a defense of the project of explaining the a priori via the notion of meaning or concept possession. It responds to certain objections that have been made to this project—in particular, that there can be no epistemically analytic sentences that are not also metaphysically analytic, and that the notion of implicit definition cannot explain a priori entitlement. The paper goes on to distinguish between two different ways in which facts about meaning might generate facts about entitlement—inferential and (...) constitutive. It concludes by outlining a theory of the latter. (shrink)

The paper develops a conception of epistemic warrant as applied to perceptual belief, called entitlement, that does not require the warranted individual to be capable of understanding the warrant. The conception is situated within an account of animal perception and unsophisticated perceptual belief. It characterizes entitlement as fulfillment of an epistemic norm that is apriori associated with a certain representational function that can be known apriori to be a function of perception. The paper connects anti-individualism, a thesis about the nature (...) of mental states, and perceptual entitlement. It presents an argument that explains the objectivity and validity of perceptual entitlement partly in terms of the nature of perceptual states-hence the nature of perceptual beliefs, which are constitutively associated with perceptual states. The paper discusses ways that an individual can be entitled to perceptual belief through its connection to perception, and ways that entitlement to perceptual belief can be undermined. (shrink)

In his seminal paper, Content Preservation, Tyler Burge defends an original account of testimonial knowledge. The originality of the account is due, in part, to the fact that it is cast within a novel epistemic framework. The central feature of that framework is the introduction of the concept of entitlement, which is alleged to be a distinctive type of positive epistemic support or warrant. Entitlement and justification, according to Burge, are sub-species of warrant. Justification is the internalist form of warrant, (...) but entitlement is epistemically externalist. My focus in this paper is Burge’s conception of entitlement, and there are three primary issues that I wish to address. What is the relationship between entitlement and the more traditional concept of justification? In what sense is entitlement epistemically externalist? Has Burge introduced a new epistemic concept or merely coined a new term for a familiar epistemic concept? (shrink)

Is the nature of testimonial warrant epistemically internalist or externalist? I will argue that the question should be answered ‘yes!’ The disjunction is not exclusive. Rather, a testimonial belief may possess epistemically internalist warrant – justification – as well as epistemically externalist warrant – entitlement. I use the label ‘pluralism’ to denote the view that there are both internalist and externalist species of genuinely epistemic warrant and argue for pluralism in the epistemology of testimony. In doing so, I begin to (...) develop an account of testimonial entitlement as well as one of testimonial justification. I conclude by illuminating a positive account by way of contrast with Paul Faulkner’s related approach. Thus, the paper is structured as follows: In Section 1, I articulate some terminology and some distinctions along with a word of motivation for the discussion. In Section 2, I develop a distinct positive case for upholding a social externalist conception of testimonial warrant. However, upholding such a view, I will argue, is compatible with embracing an epistemically internalist species of warrant for testimonial belief. In Section 3, I consider the fertility of the pluralist stance by exploring both testimonial entitlement and justification. In Section 4, I illuminate my account by contrasting it with Paul Faulkner’s “hybrid theory” of testimony. The criticism of Faulkner will serve to (i) bring out some nuances of my own proposal and (ii) provide a perspective on the nature of the internalism-externalism dispute. In section 5, I suggest that although the present exploration is incomplete and inconclusive, it is nevertheless promising. Indeed, I conclude with the bold conjecture that the pluralism in the epistemology of testimony may serve as a model for other areas of epistemology. (shrink)

Peacocke argues that all epistemic entitlements depend at bottom on a priori entitlements, determined by "constitutive conditions" for the application of concepts. He does not address familiar doubts about the distinction between constitutive and nonconstitutive conditions of application. (These doubts are based on the widely accepted idea that justification begins with all of one's current beliefs and methods and seeks to modify these only to improve their overall coherence with each other, hoping ultimately for "reflective equilibrium.") In addition, Peacocke conflates (...) issues about inference with issues about implication and proof and seriously misrepresents David Lewis' view about the content of indicative conditionals.

The notion of entitlement plays an important role in some influential epistemologies. Often the epistemological motive for introducing the concept is to accommodate certain externalist intuitions within an internalist framework or, conversely, to incorporate internalist traits into an otherwise externalist position. In this paper two prominent philosophers will be used as examples: Tyler Burge as a representative of the first option and Fred Dretske as one of the second. However, even on the assumption that the concept of entitlement is sufficiently (...) clarified, accomplishing these results is easier said than done – especially if we also want to ascribe positive epistemic value to entitlement. It will be shown that the epistemic value of entitlement is either granted at the expense of the epistemic value of justification or the value ends up below the level of value at which the epistemologists employing the concept of entitlement are aiming.

This paper takes the form of a critical discussion of Crispin Wright’s notion of entitlement of cognitive project. I examine various strategies for defending the claim that entitlement can make acceptance of a proposition epistemically rational, including one which appeals to epistemic consequentialism. Ultimately, I argue, none of these strategies is successful, but the attempt to isolate points of disagreement with Wright issues in some positive proposals as to how an epistemic consequentialist should characterize epistemic rationality.

Externalism in the philosophy of mind has been thought by many to pose a serious threat to the claim that subjects are in general authoritative with regard to certain of their own intentional states.¹ In a series of papers, Tyler Burge (1985_a_, 1985_b_, 1988, 1996) has argued that the distinctive entitlement or right that subjects have to self- knowledge in certain cases is compatible with externalism, since that entitlement is environmentally neutral, neutral with respect to the issue of the individuation (...) dependence of subjects' intentional states on factors beyond their bodies. His reason is that whereas externalism—the view that certain intentional states of persons are individuation-dependent on objects and/or phenomena external to their bodies—is a metaphysical thesis, authoritative self-knowledge is an epistemological matter. This being so, there is no reason to suppose that the two need conflict with one another. (shrink)
