What is the best account of process reliabilism about epistemic justification, especially epistemic entitlement? I argue that entitlement consists in the normal functioning (proper operation) of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Etiological functions involve consequence explanation: a belief-forming process has forming true beliefs reliably as a function just in case forming-true beliefs reliably partly explains the persistence of the process. This account paves the way for avoiding standard objections to process (...) reliabilism and situations epistemic entitlement within a normative framework of functions and functional norms. (shrink)

Corroborative evidence has a dual function in argument. Primarily, it functions to provide direct evidence supporting the main conclusion. But it also has a secondary, bolstering function which increases the probative value of some other piece of evidence in the argument. This paper argues that the bolstering effect of corroborative evidence is legitimate, and can be explained as counter–rebuttal achieved through inference to the best explanation. A model (argument diagram) of corroborative evidence, representing its structure and operation as a schematic (...) pattern of defeasible argument is also supplied. In addition to explaining the operation and theoretical foundation of corroborative evidence, the model facilitates the correct analysis and guides the evaluation (assessment and critique) of corroborative evidence as it occurs in argument.

There is a distinction between merely having the right belief, and further basing that belief on the right reasons. Any adequate epistemology needs to be able to accommodate the basing relation that marks this distinction. However, trouble arises for Bayesianism. I argue that when we combine Bayesianism with the standard approaches to the basing relation, we get the result that no agent forms their credences in the right way; indeed, no agent even gets close. This is a serious problem, for (...) it prevents us from making epistemic distinctions between agents that are doing a reasonably good job at forming their credences and those that are forming them in clearly bad ways. I argue that if this result holds, then we have a problem for Bayesianism. However, I show how the Bayesian can avoid this problem by rejecting the standard approaches to the basing relation. By drawing on recent work on the basing relation, we can develop an account of the relation that allows us to avoid the result that no agent comes close to forming their credences in the right way. The Bayesian can successfully accommodate the basing relation. (shrink)

This paper argues for externalism about justification on the basis of thought experiments. I present cases in which two individuals are intrinsically and introspectively indistinguishable and in which intuitively, one is justified in believing that p while the other is not. I also examine an argument for internalism based on the ideas that we have privileged access to whether or not our own beliefs are justified and that only internalism is compatible with this privilege. I isolate what I take to (...) be the most plausible form of privileged access to justification and show that it is compatible with externalism. (shrink)

How should the state justify its coercive rules? Public reason liberalism endorses a public justification requirement: Justifications offered for authoritative regulations must be acceptable to all members of the relevant public. However, as a criterion of legitimacy, the public justification requirement is epistemically unreliable: It prioritizes neither the exclusion of false beliefs nor the inclusion of true beliefs in justifications of political rules. This article presents an epistemic alternative to the public justification requirement. Employing epistemological theories of argumentation, we demonstrate (...) how this approach enables assessing the epistemic quality of justifications of political rules, even when the truth is difficult to establish. (shrink)

We argue that informal logic is epistemological. Two central questions concern premise acceptability and connection adequacy. Both may be explicated in tenns of justification, a central epistemological concept. That some premises are basic parallels a foundationalist account of basic beliefs and epistemic support. Some epistemological accounts of these concepts may advance the analysis of premise acceptability and connection adequacy. Infonnallogic has implications for other aspects of philosophy. If causal interpretations are acceptable premises and thus justified, does the world have a (...) causal structure? If evaluative premises are acceptable, i.e., justified, is value an objective feature of the world? (shrink)

Acceptability is a thoroughly normative epistemic notion. If a statement is acceptable, i.e. it is proper to take it as a premise, then one is justified in accepting it. We also hold that a statement is acceptable just in case there is a presumption of warrant in its favor. We thus see acceptability connected to epistemic normativity on the one hand and to warrant on the other. But there is a distinct tension in this dual connection. The dominant tradition in (...) modern epistemology sees epistemic justification as an internalist notion. We are justified in holding a belief just in case certain conditions are fulfilled of which we have privileged access. Warrant is an externalist notion. We have no privileged access to the conditions of warrant. Is our understanding of acceptability as both normative and definable in terms of presumption of warrant philosophically coherent? We shall argue that it is a philosophically coherent notion. Presumption of warrant, unlike warrant, is an internalist notion. Our position can be characterized as an externalist internal ism. It avoids the charge brought against externalism of allowing one to be justified in accepting some claim even if one has no evidence for it. We meet the classical internalist challenge that acceptance is normatively proper only if one has done one's epistemic duty and thus one is aware of the normative propriety of the acceptance by providing a non-deontological definition of epistemic justification, and arguing that this is still a sufficiently normative notion for acceptability.

The paper challenges William Alston’s argument against doxastic deontology, the view that we have epistemic duties concerning our beliefs. The core of the argument is that doxastic deontology requires voluntary control over our beliefs, which we do not have. The idea that doxastic deontology requires voluntary control is supposed to follow from the principle that ought implies can. The paper argues that this is wrong: in the OIC principle which regulates our doxastic duties the “can” does not stand for the (...) ability to shape our beliefs voluntarily. As an examination of everyday examples shows, it stands for cognitive competence, the reliable ability to acquire beliefs in compliance with the epistemic norms. The doxastic OIC principle asserts, in brief, that one is only obliged to believe something if one’s cognitive capacities are sufficiently strong. It is also explained why the doxastic duties do not require voluntary control as opposed to moral duties. This understanding of doxastic duties saves our everyday doxastic deontic judgments from Alston’s argument, but does not help the deontological conception of justification, which understands justification as not violating one’s epistemic duties. It actually provides another argument against the deontological conception: if the OIC regulating our doxastic duties is construed as suggested, the deontological conception of justification implies that one’s doxastic duties and, consequently, whether one’s belief is justified depend on one’s cognitive competence. Since cognitive competence varies from person to person, justification will not matter to truth and knowledge in the way epistemic justification is supposed to do. (shrink)

In this paper, I argue for a conditional parity thesis: if we are agents with respect to our intentions, we are agents with respect to our beliefs. In the final section, I motivate a categorical version of the parity thesis: we are agents with respect to belief and intention. My aim in this paper is to show that there is no unique challenge facing epistemic agency that is not also facing agency with respect to intention. My thesis is ambitious on (...) two fronts. First, the parity thesis is a substantive thesis about the nature of belief and intention. I argue that there is a structural parity of belief and intention; the status of whether they are agential stands and falls together. Second, the parity thesis illuminates the nature of agency. It constrains what counts as a satisfactory account of agency: either we must accept agency of both belief and intention, or we must reject both. In the final section, I argue that we have prima facie reason to accept agency of belief and intention. Finally, I diagnose why there has been such resistance to epistemic agency. Epistemic agency is problematic, but its problems are problems with agency, not problems with epistemic agency. (shrink)

I argue for the unexceptionality of evidence about what rationality requires. Specifically, I argue that, as for other topics, one’s total evidence can sometimes support false beliefs about this. Despite being prima facie innocuous, a number of philosophers have recently denied this. Some have argued that the facts about what rationality requires are highly dependent on the agent’s situation and change depending on what that situation is like. (Bradley 2019). Others have argued that a particular subset of normative truths, those (...) concerning what epistemic rationality requires, have the special property of being ‘fixed points’—it is impossible to have total evidence that supports false belief about them. (Smithies 2012; Titelbaum 2015). Each of these kinds of exceptionality permits a solution to downstream theoretical problems that arise from the possibility of evidence supporting false belief about requirements of rationality. However, as I argue here, they incur heavy explanatory burdens that we should avoid. (shrink)

The purpose of this essay is to account for privileged access or, more precisely, the special kind of epistemic right that we have to some beliefs about our own mental states. My account will have the following two main virtues. First of all, it will only appeal to those conceptual elements that, arguably, we already use in order to account for perceptual knowledge. Secondly, it will constitute a naturalizing account of privileged access in that it does not posit any mysterious (...) faculty of introspection or "inner perception" mechanism. (shrink)

In order to guide the decisions of real people who want to bring about good epistemic outcomes for themselves and others, we need to understand our epistemic values. In Knowledge in a Social World, Alvin Goldman has proposed an epistemic value theory that allows us to say whether one outcome is epistemically better than another. However, it has been suggested that Goldman's theory is not really an epistemic value theory at all because whether one outcome is epistemically better than another (...) partly depends on our non-epistemic interests. In this paper, I argue that an epistemic value theory that serves the purposes of social epistemology must incorporate non- epistemic interests in much the way that Goldman's theory does. In fact, I argue that Goldman's theory does not go far enough in this direction. In particular, the epistemic value of having a particular true belief should actually be weighted by how interested we are in the topic. (shrink)

The doctrinal paradox shows that aggregating individual judgments by taking a majority vote does not always yield a consistent set of collective judgments. Philip Pettit, Luc Bovens, and Wlodek Rabinowicz have recently argued for the epistemic superiority of an aggregation procedure that always yields a consistent set of judgments. This paper identifies several additional epistemic advantages of their consistency maintaining procedure. However, this paper also shows that there are some circumstances where the majority vote procedure is epistemically superior. The epistemic (...) value of maintaining consistency does not always outweigh the epistemic value of making true judgments. (shrink)

We all pursue epistemic goals as individuals. But we also pursue collective epistemic goals. In the case of many groups to which we belong, we want each member of the group - and sometimes even the group itself - to have as many true beliefs as possible and as few false beliefs as possible. In this paper, I respond to the main objections to the very idea of such collective epistemic goals. Furthermore, I describe the various ways that our collective (...) epistemic goals can come into conflict with each other. And I argue that we must appeal to pragmatic considerations in order to resolve such conflicts. (shrink)

Unger (1974/2000) presents an argument for skepticism that significantly differs from the more traditional arguments for skepticism. The argument is based on two premises, to wit, that knowledge would entitle the knower to absolute certainty, and that an attitude of absolute certainty is always inadmissible from an epistemic viewpoint. The present paper scrutinizes the arguments that Unger provides in support of these premises and shows that none of them is tenable. It thus concludes that Unger's argument for skepticism fails to (...) threaten the possibility of knowledge. (shrink)

Many have the intuition that the right response to the Lottery Paradox is to deny that one can justifiably believe of even a single lottery ticket that it will lose. The paper shows that from any theory of justification that solves the paradox in accordance with this intuition, a theory not of that kind can be derived that also solves the paradox but is more conducive to our epistemic goal than the former. It is argued that currently there is no (...) valid reason not to give preference to the derived accounts over the accounts from which they come. (shrink)

This book explores a question central to philosophy--namely, what does it take for a belief to be justified or rational? According to a widespread view, whether one has justification for believing a proposition is determined by how probable that proposition is, given one's evidence. In this book this view is rejected and replaced with another: in order for one to have justification for believing a proposition, one's evidence must normically support it--roughly, one's evidence must make the falsity of that proposition (...) abnormal in the sense of calling for special, independent explanation. This conception of justification bears upon a range of topics in epistemology and beyond. Ultimately, this way of looking at justification guides us to a new, unfamiliar picture of how we should respond to our evidence and manage our own fallibility. This picture is developed here. (shrink)

I here respond to four SERRC commentators on my paper ‘Perspectivism, Deontologism and Epistemic Poverty’: Shira Elqayam, Nikolaj Nottelmann, Rik Peels and Hamid Vahid. I maintain that all accounts of epistemic justification must be constrained by two limit positions which have to be avoided. One is Conceptual Limit Panglossianism (an excessively subjective, ‘emic’, ‘bounded’ and ‘grounded’, relativistic perspectivism, whereby anything the epistemic agent takes to be justified, is). The other is Conceptual Limit meliorism (an excessively objective, ‘etic’, ‘unbounded’, ‘ungrounded’, absolutism, (...) whereby the fundamental normative-epistemic notion of justification is wholly divorced from regulative, human, capacities). Within these bounds one may offer an account of rationality or epistemic justification that is closer to Meliorism or Panglossianism. Remarked upon are my respondents’ considerations on Alston, on suggestions for a separation between a more-subjective epistemic justification and a more-objective rationality, and objections to my position based on the assumption that we must embrace a very objective and truth-conducive concept of epistemic justification. (shrink)

The distinction between the regulative (‘practical’, ‘subjective’, ‘decision-procedural’) and the theoretical (‘objective’, ‘absolute’) pertains to the aims (the desiderata) of an account of justification. This distinction began in ethics and spread to epistemology. Each of internalism, externalism, is separately forced to draw this distinction to avoid a stock, otherwise fatal, argument levelled against them by the other. Given this situation however, we may finesse much partisan conflict in epistemology by simply seeing differing accounts of justification as answering to radically distinct (...) desiderata of adequacy. We should see knowledge as answering to the theoretical desideratum of adequacy alone; and rationality as answering to the regulative desideratum of adequacy alone. Objections to this ‘Gordian’ [knot] approach to epistemology (from virtues theorists and others) are rejected. Such an approach may make for accounts that violate our ordinary language intuitions; but in developing an epistemological axiology, any such intuitions are not to the point. (shrink)

Debunking arguments use empirical evidence about our moral beliefs - in particular, about their causal origins, or about how they depend on various causes - in order to reach an epistemic conclusion about the trustworthiness of such beliefs. In this thesis, I investigate the scope and limits of debunking arguments, and their implications for what we should believe about morality. I argue that debunking arguments can in principle work - they are based on plausible epistemic premises, and at least some (...) of them avoid putative problems concerning regress and redundancy. However, I also argue that some debunking arguments fall short because they are insufficiently supported by the empirical evidence. By considering different objections, analyses, and a case study, I explore the conditions for a successful debunking argument. (shrink)

Formally-inclined epistemologists often theorize about ideally rational agents--agents who exemplify rational ideals, such as probabilistic coherence, that human beings could never fully realize. This approach can be defended against the well-know worry that abstracting from human cognitive imperfections deprives the approach of interest. But a different worry arises when we ask what an ideal agent should believe about her own cognitive perfection (even an agent who is in fact cognitively perfect might, it would seem, be uncertain of this fact). Consideration (...) of this question reveals an interesting feature of the structure of our epistemic ideals: for agents with limited information, our epistemic ideals turn out to conflict with one another.

What is the connection between justification and truth in moral epistemology? The primary goal of this paper is to argue that you cannot have justified false beliefs about your own moral obligations. The secondary goal is to explain why not. Some epistemologists embrace a global truth-connection in epistemology, according to which epistemic justification is always factive. In contrast, I endorse a local truth-connection in moral epistemology, which says that epistemic justification is factive when it concerns your own moral obligations. To (...) explain this, I appeal to a version of moral rationalism, which says there are necessary truths about morality that everyone has a priori justification to believe. (shrink)

My starting point is what I call the Normative Authority Conception of justification, where S is justified in their belief that p at t (to some degree n) if and only if their believing that p at t is not ruled out by epistemic norms that have normative authority over S at t. With this in mind, this paper develops an account of doxastic justification by first developing an account of the normative authority of epistemic norms. Drawing from work in (...) political philosophy, I argue that (a) the cognitive and evaluative commitments and concerns behind our actual practices of holding each other and ourselves accountable for our beliefs reveal which epistemic norms we have consented to be under, and that (b) it is because we have consented to be under the authority of these norms – by actually holding ourselves and others accountable to them – that they in turn have normative authority over us. By connecting the authority of epistemic norms to the authority we have over ourselves in this way, the resulting account of doxastic justification (i) explains why it can be appropriate to criticize, resent, or sanction someone for having unjustified beliefs, (ii) avoids the phenomena of normative alienation and normative parochialism, and (iii) respects the social and collective nature of epistemic justification.

Why think that conscious experience of reality is any more epistemically valuable than testimony about it? I argue that conscious experience of reality is epistemically valuable because it provides cognitive contact with reality. Cognitive contact with reality is a goal of experiential inquiry which does not reduce to the goal of getting true beliefs or propositional knowledge. Such inquiry has awareness of the truth-makers of one’s true beliefs as its proper goal. As such, one reason why conscious experience of reality (...) is more epistemically valuable than testimony about reality is that it gives us more epistemic goods than only true belief or propositional knowledge. I defend this view from two rival accounts. First, that while conscious experience of reality has greater value than testimony, its value is only eudaimonic. Second, that while it has greater epistemic value than testimony, this value is not distinctive: for it only promotes truth better than testimony. (shrink)

Why are the conditions for propositional knowledge so difficult to discover or devise in this post-Gettier age? Why do not most epistemologists agree on roughly the same analysis as they appear to have done in the pre-Gettier paradise? I argue that the problem lies in that fact that the epistemologists intuitive concept of knowledge appeals to desiderata that probably cannot be satisfied. Unfortunately, if we abandon some of these desiderata, it is difficult to settle on a concept of knowledge which (...) is not too remote from our initial intuitions. I suggest that epistemology may be better off without the concept of knowledge. There are plenty of other interesting notions for us to be going on with. (shrink)

As the title of this essay suggests, my concern is with the issue of what are economic models. However, the goal of the paper is not to offer an in-depth study on multiple approaches to modelling in economics, but rather to overcome the dichotomical divide between conceptualizing models as isolations and constructions. This is done by introducing the idea of economic models as believable worlds, precisely descriptions of mechanisms that refer to the essentials of the modelled targets. In doing so (...) I make use of the Woodward’s (2002) conceptualization of mechanisms. It is shown that such models do not offer the perfectly true descriptions of the actual world but justified beliefs about the modelled, precisely they aim at maximizing truth and minimizing falsity in a large body of belief about the real world. The analysis throughout the paper is supported by in-depth examination of the Varian’s (1980) model of sales that is here treated as a representative way of reasoning in neoclassical economics.

Sometimes we make mistakes, even when we try to do our best. When those mistakes are about normative matters, such as what is required, this leads to a puzzle. This puzzle arises from the possibility of misleading evidence about what rationality requires. I argue that the best way to solve this puzzle is to distinguish between two kinds of evaluation: requirement and appraisal. The strategy I defend connects three distinct debates in epistemology, ethics, and normativity: the debate over how our (...) theories of epistemic rationality should accommodate misleading evidence, the debate over the relationship between complying with requirements and deserving particular appraisals, and the debate over whether normative ignorance can excuse. Part 1 shows how three apparently plausible claims about epistemic rationality generate a puzzle when agents have misleading evidence about what rationality requires. Part 2 solves this puzzle by distinguishing between evaluations of requirement and appraisal and rejecting the idea that one is required to conform to the Enkratic Principle. I argue instead that complying with the Enkratic Principle provides defeasible evidence that the agent should be positively appraised. One of the consequences of this solution is that false normative beliefs can sometimes excuse agents from negative appraisal they would otherwise deserve for violating requirements. Part 3 defends the view that false normative belief can sometimes excuse against the rival views that false normative belief always excuses, and that false normative belief never excuses. I argue that false normative belief can sometimes excuse violations of requirements, when it is the case that the agent has done what it is reasonable to expect of her. (shrink)

نظریة مبناگرایی یکی از دیرینه‌ترین و مهم‌ترین رهیافت‌ها در معرفت‌شناسی تلقی ‌می‌شود. از دو قسم اساسی مبناگرایی، مبناگرایی کلاسیک و معتدل، در مقالة حاضر، مبناگرایی کلاسیک را انتخاب کرده‌ایم و از دو شکل مبناگرایی درون‌گرایانه و برون‌گرایانه، دومی را بررسی می‌کنیم. در نوشتار حاضر هر دو دسته از مبناگرایی ساده و مضاعف و تمایزات اساسی آن‌ها را کاویده‌ایم. ادعای اصلی مبناگرایی کلاسیک برون‌گرایانه این است که باورهای ما به دو دستة پایه و استنتاجی تقسیم می‌شوند و همة باورهای استنتاجی ما، (...) در فرایند توجیهی، باید به باورهای پایه بازگردند، در غیر این‌ صورت دچار دور یا تسلسل خواهیم شد. در مقالة حاضر کوشش خواهد شد تا علاوه ‌بر آن‌که کاستی‌های نظریة مبناگرایی نشان داده می‌شود به این کاستی‌ها، بر اساس نظام معرفتی علامه، پاسخ‌هایی داده شود. علامه طباطبایی در نظام معرفتی خود دستگاهی از روابط میان باورها، بر اساس سه اصل، سامان می‌دهد که این دستگاه اولاً، تمایز میان بدیهیات اولیه و ثانویه را مشخص ‌می‌کند؛ ثانیاً، ضمن نقد معرفت خطاپذیر از معرفت خطاناپذیر دفاع می‌کند؛ ثالثاً، روش دست‌یابی به معرفت یقینی را تبیین ‌می‌کند؛ و بالاخره، ضمن نقد بر مبناگرایی ساده، مبناگرایی مضاعف را رویکرد درست بر‌می‌شمارد. خطاپذیری و خطاناپذیری و درنتیجه، تصحیح باورهای پایه اساسی‌ترین ضعف و کاستی در مبناگرایی است. با توجه به مبنای علامه طباطبایی، دربارة معرفت یقینی، که باید درنهایت همة معرفت‌ها به بدیهیات ختم و بدیهیات ثانویه نیز با روابط ویژه‌ای به بدیهیات اولی یا سه اصل اولی منتهی شوند؛ می‌توان خلل اساسی در مبناگرایی، که همان معرفت تزلزل‌پذیر غیر یقینی است، را مورد پرسش قرار داد. مهم‌ترین دستاورد علامه، در حوزة معرفتی، دفاع از معرفت یقینی بر اساس اولیات و امکان دست‌یابی به معرفت خطاناپذیر است.

By “physical probability” I mean the empirical concept of probability in ordinary language. It can be represented as a function of an experiment type and an outcome type, which explains how non-extreme physical probabilities are compatible with determinism. Two principles, called specification and independence, put restrictions on the existence of physical probabilities, while a principle of direct inference connects physical probability with inductive probability. This account avoids a variety of weaknesses in the theories of Levi and Lewis.

In October 2009 I decided to stop doing philosophy. This meant, in particular, stopping work on the book that I was writing on the nature of probability. At that time, I had no intention of making my unfinished draft available to others. However, I recently noticed how many people are reading the lecture notes and articles on my web site. Since this draft book contains some important improvements on those materials, I decided to make it available to anyone who wants (...) to read it. That is what you have in front of you. The account of Laplace’s theory of probability in Chapter 4 is very different to what I said in my seminar lectures, and also very different to any other account I have seen; it is based on a reading of important texts by Laplace that appear not to have been read by other commentators. The discussion of von Mises’ theory in Chapter 7 is also new, though perhaps less revolutionary. And the final chapter is a new attempt to come to grips with the popular, but amorphous, subjective theory of probability. The material in the other chapters has mostly appeared in previous articles of mine but things are sometimes expressed differently here. I would like to say again that this is an incomplete draft of a book, not the book I would have written if I had decided to finish it. It no doubt contains poor expressions, it may contain some errors or inconsistencies, and it doesn’t cover all the theories that I originally intended to discuss. Apart from this preface, I have done no work on the book since October 2009. (shrink)

In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

The problem of rational prediction, launched by Wesley Salmon, is without doubt the Achilles heel of the critical method defended by Popper. In this paper, I assess the response given both by Popper and by the popperian Alan Musgrave to this problem. Both responses are inadequate and thus the conclusion of Salmon is reinforced: without appeal to induction, there is no way to make of the practical prediction a rational action. Furthermore, the critical method needs to be vindicated if one (...) pretends that its application is suitable for the preference of a hypothesis. I argue that the nature of this vindication is such that it may be applied also to induction. Thus, to be a popperian is a good reason also to be an inductivist. (shrink)

This paper is a reconstruction and analysis of Thomas Reid’s epistemology, based upon an examination of his extant manuscripts and publications. I argue that, in Reid’s view, a certain degree of “evidence” (or, as I shall say, ‘epistemic justification’) is that which distinguishes mere true belief from knowledge; and that this degree of justification may be ascribed to a person’s belief if and only if (i) the evidence upon which her belief is grounded is such that she holds it with (...) “certainty”; (ii) she has a “sound understanding”; (iii) she has a distinct conception of the object of her belief; and, finally, (iv) she has formed her belief “without prejudice”.

A basic question for virtue epistemology is whether it represents a ‘third force’ – a different source of normativity to that offered by internalism and externalism. It is argued that virtue epistemology does not offer us a distinct source of normativity. It is also argued that virtue theories offer us nothing that can unify the internalist and externalist sub-components of their preferred state of ‘virtue’. Claims that phronesis can unify a virtues-based axiology are specifically opposed.

Most epistemologists agree that epistemic justification is required for knowledge. This requirement is usually formulated in one of two ways: S knows that p only if S is justified in believing that p. S knows that p only if S's belief that p is justified. Surprisingly and are generally regarded as synonymous formulations of the justification condition. In Chapter 1, I argue that such a synonymy thesis is mistaken and that, in fact, and specify substantively different requirements. requires that the (...) person be justified, whereas requires that the belief in question be justified, and intuitively, these constitute different requirements. Thus, it is concluded that and employ inherently different kinds of epistemic justification in their respective analysantia. I dub them "personal justification" and "doxastic justification", respectively. The remainder of the dissertation is devoted to demonstrating both the legitimacy and the importance of the personal/doxastic justification distinction. For example, the distinction helps account for the divergent intuitions that regularly arise regarding justificatory evaluations in demon-world contexts. ;In Chapters 2 and 3 I provide analyses for doxastic and personal justification. Chapter 2 spells out an externalist reliabilist account of doxastic justification which safely avoids demon-world counterexamples. Chapter 3 advances an internalist coherence account of personal justification. In defending this coherence theory, I argue that all foundation theories are false and that the regress argument on which they are predicated is unsound. ;In Chapter 4, I propose an analysis of ordinary knowledge which only requires doxastic justification. Nevertheless personal justification plays a negative, undermining role in the analysis. I then demonstrate that this analysis of knowledge is immune to typical Gettier examples. It also remains unscathed by Harman's beefed-up Gettier cases. Finally, I consider a stronger analysis of knowledge requiring both doxastic and personal justification. Though the latter analysis proves too strong for ordinary knowledge, it remains interesting as an analysis of a more intellectualistic kind of knowledge. ;The final chapter examines the internalist/externalist controversy and demonstrates that this controversy is yet another manifestation of the personal/doxastic justification conflation.

This paper approaches the current epistemological debate on peer disagreement from a neo-Pyrrhonian perspective, thus adopting a form of skepticism which is more radical than those discussed in the literature. It makes use of argumentative strategies found in ancient Pyrrhonism both to show that such a debate rests on problematic assumptions and to block some maneuvers intended to offer an efficacious way of settling a considerable number of peer disputes. The essay takes issue with three views held in the peer (...) disagreement debate: there is an objective fact of the matter about at least most controversial questions; we possess theory-neutral evidence bearing on those questions which grants us access to the truth of the matter; and many peer controversies are resolved by attending to which disputant has correctly evaluated the objective evidence. With respect to the first two views, it is argued that the belief in both objective facts and theory-neutral evidence is subject to fierce dispute, and should not therefore be taken for granted in the discussion of peer disagreement. As for the third view, it is argued that from either a first- or a third-person perspective, there seems to be epistemic symmetry between the disputants which makes it necessary to suspend judgment.

The notion of an ideal reasoner has several uses in epistemology. Often, ideal reasoners are used as a parameter of (maximum) rationality for finite reasoners (e.g. humans). However, the notion of an ideal reasoner is normally construed in such a high degree of idealization (e.g. infinite/unbounded memory) that this use is unadvised. In this dissertation, I investigate the conditions under which an ideal reasoner may be used as a parameter of rationality for finite reasoners. In addition, I present and justify (...) the research program of computational epistemology, which investigates the parameter of maximum rationality for finite reasoners using computer simulations.

This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)

For any normative domain, we can theorize about what is good in that domain. Such theories include utilitarianism, a view about what is good morally. But there are many domains other than the moral; these include the prudential, the aesthetic, and the intellectual or epistemic. In this last domain, it is good to be knowledgeable and bad to ignore evidence, quite apart from the morality, prudence, and aesthetics of these things. This dissertation builds a theory that stands to the epistemic (...) domain as utilitarianism stands to the moral domain. It builds an epistemic value theory. (shrink)

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (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.
