I argue that our justification for beliefs about the external physical world need not be constituted by any justified beliefs about perceptual experiences. In this way our justification for beliefs about the physical world may be nondoxastic and this differentiates my proposal from traditional foundationalist theories such as those defended by Laurence BonJour, Richard Fumerton, and Timothy McGrew. On the other hand, it differs from certain non-traditional foundationalist theories such as that defended by James Pryor according to which perceptual experience (...) is sufficient to justify beliefs about the external world. I propose that justification for propositions describing our perceptual experiences partially constitutes any justification we may possess for beliefs concerning the external world. In this way, our justification for beliefs about the physical world may only be inferential since it is grounded in any justification we have for at least one other proposition. This theory occupies an intermediate position between the two aforementioned foundationalist accounts, which allows it to sidestep problems that confront each of them. (shrink)

According to the extended mind thesis, cognitive processes are not confined to the nervous system but can extend beyond skin and skull to notebooks, iPhones, computers and such. The extended mind thesis is a metaphysical thesis about the material basis of our cognition. As such, whether the thesis is true can have implications for epistemological issues. Carter has recently argued that safety-based theories of knowledge are in tension with the extended mind hypothesis, since the safety condition implies that there is (...) an epistemic difference between subjects who form their beliefs via their biological capacities and between subjects who have extended their cognition. Kelp, on the other hand, has argued that a safety-based theory of knowledge can be correct only if the extended mind thesis is true. While these claims are not logically inconsistent, they do leave the safety theorist in an uncomfortable position. I will argue that safety-based theories of knowledge are not hostage to the truth of the extended mind thesis, and that once the safety condition is properly understood it is not in tension with the extended mind thesis.

Coherence is a key concept in many accounts of epistemic justification within ‘traditional’ analytic epistemology. Within formal epistemology, too, there is a substantial body of research on coherence measures. However, there has been surprisingly little interaction between the two bodies of literature. The reason is that the existing formal literature on coherence measure operates with a notion of belief system that is very different from—what we argue is—a natural Bayesian formalisation of the concept of belief system from traditional epistemology. Therefore, (...) formal epistemology has so far only been concerned with one particular—arguably not even very natural—way of formalising coherence of belief systems; it has by no means refuted the viability of coherentism. In contrast to the existing literature, we formalise belief systems as families of assignments of (conditional) degrees of belief (which may be compatible with several subjective probability measures). Within this framework, we propose a Bayesian formalisation of the thrust of BonJour’s coherence concept in The structure of empirical knowledge (Harvard University Press, Cambridge, 1985), using a combination of Bayesian confirmation theory and basic graph theory. In excursions, we introduce graded notions for both logical and probabilistic consistency of belief systems—the latter being based on certain geometrical structures induced by probabilistic belief systems. For illustration, we reconsider BonJour’s “ravens” challenge (op. cit., p. 95f.). Finally, potential objections to our proposed formal coherence notion are explored. (shrink)

The author applies an economic theory of ordinary knowledge—street-level epistemology—to the popular understanding of science. Street-level theory is essentially economic and pragmatic. If it is very costly to learn something, you are less likely to learn it. If you need to know it, you are more likely to find out about it (although what you find out might be wrong). For most of what you know, you essentially rely on others as sources (some of these others might be "experts," but (...) many are not). In general, the ordinary person does not need to know modern physics and cannot be expected to. But most of us generally need medical knowledge on occasion, and we can be expected to go in quest of it. Our primary task in seeking medical knowledge, however, is to settle on whom we count as relevant experts. Key Words: knowledge • epistemology • scientific knowledge • ordinary knowledge. (shrink)

In this article, I argue that access internalism should replace preservationism, which has been called “a received view” in the epistemology of memory, as the standard position about memorial justification. My strategy for doing so is two-pronged. First, I argue that the considerations which motivate preservationism also support access internalism. Preservationism is mainly motivated by its ability to answer the explanatory challenges posed by the problem of stored belief and the problem of forgotten evidence. However, as I will demonstrate, access (...) internalism also has the resources to provide plausible solutions to those problems. Second, I argue that preservationism faces a couple of problems which access internalism avoids. Doing so, I present a new scenario which, on the one hand, functions as a counterexample to preservationism, and, on the other hand, provides intuitive support for access internalism. Moreover, I also demonstrate how preservationism, in light of recent research in cognitive psychology, is vulnerable to skepticism about memorial justification, whereas access internalism remains unthreatened.

Many epistemologists think we can derive important theoretical insights by investigating the English word ‘know’ or the concept it expresses. However, fewer than six percent of the world’s population are native English speakers, and some empirical evidence suggests that the concept of knowledge is culturally relative. So why should we think that facts about the word ‘know’ or the concept it expresses have important ramifications for epistemology? This paper argues that the concept of knowledge is universal: it is expressed by (...) some word in every natural language. I also explore the implications of this thesis for philosophical methodology. (shrink)

We prove that four theses commonly associated with coherentism are incompatible with the representation of a belief state as a logically closed set of sentences. The result is applied to the conventional coherence interpretation of the AGM theory of belief revision, which appears not to be tenable. Our argument also counts against the coherentistic acceptability of a certain form of propositional holism. We argue that the problems arise as an effect of ignoring the distinction between derived and non-derived beliefs, and (...) we suggest that the kind of coherence relevant to epistemic justification is the coherence of non-derived beliefs.

The article traces interpretative mechanisms hidden in Chomsky's Transformational Model. The framework is that of epistemological criticism, investigating the intertwining of interpretation, context and intuition. My hypothesis is that the Transformational Model is an example of a quasi-axiomatic, intuition-based grammar. It is not a scientific model of Competence but a scientistic description of Performance (teleological corpora). The scientistic décor is thus an eristic stratagem to hide arbitrary interpretation. The discussion is empirically substantiated by analyzing the notion of grammaticality, the tectonics (...) of the Transformational Model and the phenomenology of countable/uncountable nouns. Key Words: interpretative mechanisms • intuition • epistemology • transformational model • context • Dasein • performance • competence. (shrink)

Dialogues and dialectics have come to playan important role in the field of ArtificialIntelligence and Law. This paper describes thelegal-theoretical and logical background of this role,and discusses the different services into whichdialogues are put. These services include:characterising logical operators, modelling thedefeasibility of legal reasoning, providing the basisfor legal justification and identifying legal issues,and establishing the law in concrete cases. Specialattention is given to the requirements oflaw-establishing dialogues.

Although the AGM theory established a paradigm for the theory of belief revision, which is generally regarded as a kind of standard in the field, it is also frequently criticized as inadequate because it neglects justificational structures. Other theories of belief revision are similarly remiss in this regard. So far, little has been done to address this shortcoming. This paper aims to fill this gap. Following a critical analysis of the AGM theory, a justification operator is introduced as a formal (...) means to incorporate justificational structures into a belief revision theory. An AGM style belief revision theory is proposed that is based on such a justification operator. The theory is presented in an axiomatic form. Representation theorems link the axioms with constructive belief change mechanisms. The proposed theory addresses the problems of the AGM theory and similar approaches that neglect justificational structures. (shrink)

A number of contemporary philosophers endorse a Pyrrhonian theme: that one has knowledge only if one knows or understands that one’s beliefs are reliably formed. Otherwise, one is like a man who grasps gold in the dark: such a man is successful, but his success is a matter of luck, and so not creditable to him. It is argued that the skeptical problem and the problem of moral luck share a common structure and a common solution. Specifically, a virtue-theoretic approach (...) helps us to understand important relations among luck, success and credit for success. It is argued that knowledge is an instance of success through virtue, and that, in general, success through virtue is creditable to the virtuous agent. (shrink)

A number of virtue epistemologists endorse the following thesis: Knowledge is true belief resulting from intellectual virtue, where Ss true belief results from intellectual virtue just in case S believes the truth because S is intellectually virtuous. This thesis commits one to a sort of contextualism about knowledge attributions. This is because, in general, sentences of the form X occurred because Y occurred require a contextualist treatment. This sort of contextualism is contrasted with more familiar versions. It is argued that (...) the position: (a) yields a better solution to the lottery problem, and (b) may be grounded in a more general theory of virtue and credit. (shrink)

Philosophy and Phenomenological Research, EarlyView.

Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

In this paper we give reasons to think that reflective epistemic subjects cannot possess mere animal knowledge. To do so we bring together literature on defeat and higher-order evidence with literature on the distinction between animal knowledge and reflective knowledge. We then defend our argument from a series of possible objections.

This book deserves kudos. It presents one of the more novel versions of reliabilism to appear in recent years. The style is fast-paced and energetic, with no sacrifice in philosophical precision. It applies original interpretations of perceptual science to central issues in traditional epistemology, and should thereby earn itself a prominent place in the naturalistic epistemology literature. Finally, the book is more comprehensive than its title suggests. It illuminates a great many issues of traditional epistemology beyond perception, providing an up-to-date (...) and thorough-going basic epistemology. (shrink)

Epistemology has recently witnessed a number of efforts to rehabilitate rationalism, to defend the existence and importance of a priori knowledge or warrant construed as the product of rational insight or apprehension (Bealer 1987; Bigelow 1992; BonJour 1992, 1998; Burge 1998; Butchvarov 1970; Katz 1998; Plantinga 1993). This effort has sometimes been coupled with an attack on naturalistic epistemology, especially in BonJour 1994 and Katz 1998. Such coupling is not surprising, because naturalistic epistemology is often associated with thoroughgoing empiricism and (...) the rejection of the a priori. In this paper, however, I shall present a conception of naturalistic epistemology that is entirely compatible with a priori justification or knowledge. The resulting conception, I claim, gives us a better appreciation of the respective merits of the rational and the empirical, as well as a better understanding of how moderate epistemological naturalism comports, at least in principle, with moderate rationalism. This paper defends moderate rationalism; but it does not defend everything rationalists have often wanted, only what it is reasonable to grant them. (shrink)

It is a commonplace that contemplation of an imaginary particular may have cognitive and motivational effects that differ from those evoked by an abstract description of an otherwise similar state of affairs. In his Treatise on Human Nature, Hume ([1739] 1978) writes forcefully of this.

Thought experiments as counterexamples are a familiar tool in philosophy. Frequently understanding a vignette seems to generate a challenge to a target theory. In this paper I explore the content of the judgement that we have in response to these vignettes. I first introduce several competing proposals for the content of our judgement, and explain why they are inadequate. I then advance an alternative view. I argue that when we hear vignettes we consider the normal instances of the vignette. If (...) the normal instance of the vignette exhibits a counter-instance, the vignette constitutes a challenge to the target theory. I argue that this proposal shows how responses to vignettes are an ordinary, everyday judgement, and I explain how the proposal avoids the problems generated by competing theories. Finally, I argue this ‘normalcy proposal’ most naturally accords with our understanding of the method. (shrink)

For some years now, Michael Bergmann has urged a dilemma against internalist theories of epistemic justification. For reasons I explain below, some epistemologists have thought that Michael Huemer’s principle of Phenomenal Conservatism can split the horns of Bergmann’s dilemma. Bergmann has recently argued, however, that PC must inevitably, like all other internalist views, fall prey to his dilemma. In this paper, I explain the nature of Bergmann’s dilemma and his reasons for thinking that PC cannot escape it before arguing that (...) he is mistaken: PC can indeed split its horns. (shrink)

This essay explores the epistemological significance of the kinds of beliefs that grow out of traumatic experiences, such as the rape survivor's belief that she is never safe. On current theories of justification, beliefs like this one are generally dismissed due to either insufficient evidence or insufficient propositional content. Here, Freedman distinguishes two discrete sides of the aftermath of psychic trauma, the shattered self and the shattered worldview. This move enables us to see these beliefs as beliefs; in other words, (...) as having cognitive content. Freedman argues that what we then need is a theory of justification that allows us to handpick reliable sources of information on sexual violence, and give credibility where deemed appropriate. She advances a mix of reliabilism and coherentism that privileges feminism. On this account, the evidence for the class of beliefs in question will depend on an act of sexual violence (or testimony, or statistics) to the extent that the act is a reliable indication of the prevalence of sexual violence against women.

We must allow that knowledge can be transmitted. But to allow this is to allow that an individual can know a proposition despite lacking any evidence for it and reaching belief by an unreliable means. So some explanation is required as to how knowledge rather than belief is transmitted. This paper considers two non-individualistic explanations: one in terms of knowledge existing autonomously, the other in terms of it existing as a property of communities. And it attempts to decide what is (...) at issue between these explanations. (shrink)

In his famous essay "The Ethics of Belief," William K. Clifford claimed "it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence." ). One might claim that a corollary to Clifford's Law is that it is wrong, always, everywhere, and for anyone, to withhold belief when faced with sufficient evidence. Seeming to operate on this principle, many religious philosophers—from St. Anselm to Alvin Plantinga—have claimed that non-believers are psychologically or cognitively deficient if they refuse to believe (...) in the existence of God, when presented with evidence for His existence in the form of relevant experience or religious arguments that are prima facie unassailable. Similarly, many atheists fail to see how believers can confront the problem of evil and still assert their belief in a benevolent, omnipotent, and omniscient Creator. In this paper, I propose to explain why religious arguments so often fail to persuade . In doing so, I first offer an account of persuasion and then apply it to religious arguments. I go on to argue that at least some religious arguments commit a form of question-begging, which I call "begging the doxastic question." An argument begs the doxastic question, on my account, when a subject would find the argument persuasive only if she antecedently believes the argument's conclusion. This form of question begging is not, strictly speaking, a case of circularity and thus, is not a fallacy; rather, it would explain why one coming to the argument would fail to be persuaded by it unless he already accepted its conclusion. This has the effect, when applied to religious argumentation, that religious arguments are rarely persuasive, which raises the further question: what good are religious arguments? I end by suggesting some non-persuasive functions of religious argument. Finally, I suggest that a full understanding of religious argumentation should give evidentialists pause, for religious beliefs look less like belief states that are sensitive to evidentiary states and more like framework principles or fundamental commitments. (shrink)

This article examines Keith Lehrer's distinction between belief and acceptance and how it differs from other accounts of belief and of the family of doxastic attitudes. I sketch a different taxonomy of doxastic attitudes. Lehrer's notion of acceptance is mostly epistemic and at the service of his account of the "loop of reason", whereas for other writers acceptance is mostly a pragmatic attitude. I argue, however, that his account of acceptance underdetermines the role that the attitude of trust plays in (...) his analysis of reason. (shrink)

In this article, I develop and defend a version of reliabilism – internal reasons reliabilism – that resolves the paradox of epistemic luck, solves the Gettier problem by ruling out veritic luck, is immune to the generality problem, resolves the internalism/externalism controversy, and preserves epistemic closure.

The paper takes as its starting point the observation that people can be led to retract knowledge claims when presented with previously ignored error possibilities, but offers a noncontextualist explanation of the data. Fallibilist epistemologies are committed to the existence of two kinds of Kp -falsifying contingencies: (i) Non-Ignorable contingencies [NI-contingencies] and (ii) Properly-Ignorable contingencies [PI-contingencies]. For S to know that p, S must be in an epistemic position to rule out all NI-contingencies, but she need not be able to (...) rule out the PI-contingencies. What is required vis-à-vis PI-contingencies is that they all be false . In mentioning PI-contingencies, an interlocutor can lead S mistakenly to think that these contingencies are NI-contingencies, when in fact they are not. Since S cannot rule out these newly mentioned contingencies and since she mistakenly takes them to be NI-contingencies , it is quite natural that she retract her earlier knowledge claim. In short, mentioning NI-contingencies creates a distortion effect. It makes S think that the standards for knowledge are higher than they actually are, which in turn explains why she mistakenly thinks she lacks knowledge. Conclusion: The primary linguistic data offered in support of contextualism can be explained without resorting to contextualism. (shrink)

Facts about justification are not brute facts. They are epistemic facts that depend upon more fundamental non-epistemic facts. Internalists about justification often argue for mentalism, which claims that facts about justification supervene upon one’s non-factive mental states, using Lehrer and Cohen’s :191–207, 1983) New Evil Demon Problem. The New Evil Demon Problem tells you to imagine yourself the victim of a Cartesian demon who deceives you about what the external world is like, and then asks whether you nevertheless have justification (...) for your beliefs about the external world. Internalists and externalists agree that there is something that is epistemically good or valuable about both your actual beliefs and your beliefs in the demon scenario. Internalists claim that the epistemic property which these sets of beliefs share most intuitively should be thought of as sameness of justification. Externalists, on the other hand, reject this claim, usually either by challenging the internalist intuition directly, or by arguing that there is a more plausible way to think about the epistemic property in question. Recently, both kinds of externalist objection have been raised against the argument from the New Evil Demon Problem for mentalism. The goal of this paper is to defend the argument against three prominent objections—a pair of which is offered by Littlejohn :399–434, 2009) and one by Williamson Rationality and the good: critical essays on the ethics and epistemology of Robert Audi, Oxford University Press, Oxford, 2007; in: Dutant J, Dohrn D The new evil demon, Oxford University Press, Oxford, 2016).

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

Some of the most well-known arguments against epistemic externalism come in the form of thought experiments involving subjects who acquire beliefs through anomolous means such as clairvoyance. These thought experiments purport to provide counterexamples to the reliabilist conception of justification: their subjects are intuitively epistemically unjustified, yet meet reliabilist externalist criteria for justification. In this article, I address a recent defence of externalism due to Daniel Breyer, who argues that externalists need not consider such subjects justified, since they fail to (...) own those beliefs in a way required for epistemic evaluability. I argue that the concept of belief ownership Breyer adopts leaves his account open to related counterexamples, and suggest a modification, drawing on analogies between these cases and cases of delusions, such as thought insertion. I will argue that a concept of authorship developed in the literature on delusions better grounds the sense of attribution required for epistemic evaluability. (shrink)

Glymour’s theory of bootstrap confirmation is a purely qualitative account of confirmation; it allows us to say that the evidence confirms a given theory, but not that it confirms the theory to a certain degree. The present paper extends Glymour’s theory to a quantitative account and investigates the resulting theory in some detail. It also considers the question how bootstrap confirmation relates to justification.

The notion of perceptual content is commonly introduced in the analysis of perception. It stems from an analogy between perception and propositional attitudes. Both kinds of mental states, it is thought, have conditions of satisfaction. I try to show that on the most plausible account of perceptual content, it does not determine the conditions under which perceptual experience is veridical. Moreover, perceptual content must be bipolar (capable of being correct and capable of being incorrect), whereas perception as a mental state (...) is not (if it is veridical, it is essentially so). This has profound consequences for the epistemological view that perception is a source of knowledge. I sktech a two-level epistemology which is consistent with this view. I conclude that the analogy between perception and propositional attitudes, from which the notion of perceptual content is born, may be more misleading than it is usually thought. (shrink)

White, Christensen, and Feldman have recently endorsed uniqueness, the thesis that given the same total evidence, two rational subjects cannot hold different views. Kelly, Schoenfield, and Meacham argue that White and others have at best only supported the weaker, merely intrapersonal view that, given the total evidence, there are no two views which a single rational agent could take. Here, we give a new argument for uniqueness, an argument with deliberate focus on the interpersonal element of the thesis. Our argument (...) is that the best explanation of the value of promoting rationality is an explanation that entails uniqueness. (shrink)

It is quite unequivocal that Kuhn was committed to (some version of) naturalism; that he defended, especially in his later work, the autonomy of scientific rationality; and that he rejected the correspondence theory of truth, i.e., the traditional realistic conception of the world’s mind-independence. In this paper, I argue that these three philosophical perspectives form an uneasy triangle, for while it is possible to coherently defend each of them separately or two of them combined, holding all three leads to incoherence. (...) Hence, the only option is to reject one of them in a way that is both compatible with Kuhnian historiography and philosophically fruitful. My purpose in this paper is not exegetical. My ambition is to sketch a coherent philosophical framework which does justice to Kuhn’s historiographical model for scientific change and avoids the philosophical costs of relativism and anti-naturalism. In particular, I argue in favor of the following interconnected positions: (1) Given the role of anomalies in Kuhn’s historiographical model, the latter satisfies the two fundamental conditions for acknowledging the mind-independence of the world: the ‘irreducibility condition’ and the ‘objectivity condition’, (2) Kuhn’s rejection of the notion of an ‘Archimedean platform’ does not entail that the truth-value of beliefs doesn’t play a role in the explanation of their change, (3) Adopting scientific realism is the only way to defend the autonomy of scientific rationality within a naturalistic philosophical framework. However, adopting realism leads to a liberal rather than an eliminative version of naturalism. (shrink)

Michael Huemer has argued for the justification principle known as phenomenal conservativism by employing a transcendental argument that claims all attempts to reject phenomenal conservativism ultimately are doomed to self-defeat. My contribution presents two independent arguments against the self-defeat argument for phenomenal conservativism after briefly presenting Huemer’s account of phenomenal conservativism and the justification for the self-defeat argument. My first argument suggests some ways that philosophers may reject Huemer’s premise that all justified beliefs are formed on the basis of seemings. (...) In the second argument I contend that phenomenal conservativism is not a well-motivated account of internal justification, which is a further reason to reject the self-defeat argument. Consequently, the self-defeat argument fails to show that rejecting phenomenal conservativism inevitably leads one to a self-defeating position. (shrink)

Michael Bergmann has argued that internalist accounts of justification face an insoluble dilemma. This paper begins with an explanation of Bergmann’s dilemma. Next, I review some recent attempts to answer the dilemma, which I argue are insufficient to overcome it. The solution I propose presents an internalist account of justification through direct acquaintance. My thesis is that direct acquaintance can provide subjective epistemic assurance without falling prey to the quagmire of difficulties that Bergmann alleges all internalist accounts of justification cannot (...) surmount.

In this paper I look at Fred Dretske’s account of information and knowledge as developed in Knowledge and The Flow of Information. In particular, I translate Dretske’s probabilistic definition of information to a modal logical framework and subsequently use this to explicate the conception of information and its flow which is central to his account, including the notions of channel conditions and relevant alternatives. Some key products of this task are an analysis of the issue of information closure and an (...) investigation into some of the logical properties of Dretske’s account of information flow. (shrink)

I develop a strategy for representing epistemic states and epistemic changes that seeks to be sensitive to the difference between voluntary and involuntary aspects of our epistemic life, as well as to the role of pragmatic factors in epistemology. The model relies on a particular understanding of the distinction between full belief and acceptance , which makes room for the idea that our reasoning on both practical and theoretical matters typically proceeds in a contextual way. Within this framework, I discuss (...) how agents can rationally shift their credal probability functions so as to consciously modify some of their contextual acceptances; the present account also allows us to represent how the very set of contexts evolves. Voluntary credal shifts, in turn, might provoke changes in the agent’s beliefs, but I show that this is actually a side effect of performing multiple adjustments in the total lot of the agent’s acceptance sets. In this way we obtain a model that preserves many pre-theoretical intuitions about what counts as adequate rationality constraints on our actual practices—and hence about what counts as an adequate, normative epistemological perspective.

An important trend in contemporary epistemology centers on elaborating an old idea of pragmatist pedigree: theory selection (and in general the process of changing view and fixing beliefs) presupposes epistemic values. This article focuses on analyzing the case where epistemic values are indeterminate or when the sources of valuation are multiple (epistemic values like coherence and simplicity need not order options in compatible ways). According to the theory that thus arises epistemic alternatives need not be fully ordered by an underlying (...) notion of information-value and therefore the usual economic techniques of optimization cannot be applied in order to compute optimal contractions. But in cases of this sort it is still rational to maximize, i.e. to deem an option as choosable when it is not known to be worse that any other. We present here basic results about a notion of liberal contraction based on maximizing quasi-orderings. This requires the previous solution of some open problems in the theory of rational choice functions, namely a full characterization of choice functions rationalizable in terms of maximization of quasi-transitive relations. We conclude by discussing the problem of what is the adequate feasible set for calculating maximizing solutions for contraction problems and by considering the epistemological roots of some counterexamples against the most fundamental axioms on choice functions (like α). While the first part of the paper shows how economic insights can be used to improve our understanding of the principles of belief formation and change, this final section reverses this strategy by showing the utility of epistemological insights and techniques for providing invariance conditions capable of regulating the applicability of the pure principles of choice.

This paper seeks to provide some of the roles of philosophy in the field of academic ethics.

This paper challenges Professor Myles Brand’s position on the role and value of intercollegiate athletics in U.S. colleges and universities on the ground that it fails to account for considerations of deep fiscal responsibility. It presents both a philosophical and ethical criticism of his position that broadens the discussion beyond athletics to include a particular kind of higher educational institution more generally.

This essay argues that Alvin I. Goldman's truth-linked theory of group knowledge (veritism) omits individual components of social cognition, that all group based theories of knowledge lead to scepticism, and that if any sense is to be made of social knowledge, it must be done on individualist lines. I argue that Goldman's veritism can be reconstructed by adopting a reliabilist theory,social reliabilism. And I argue that Goldman's objections to a particular sort of consensualism are not telling. So there are now (...) two plausible and competing theories of social knowledge-social reliabilism and consensualism. (shrink)

In a recent article in this journal, Andrew Johnson seeks to defend the “New Atheism” against several objections. We provide a philosophical assessment of his defense of contemporary atheistic arguments that are said to amount to bifurcation fallacies. This point of discussion leads to our critical discussion of the presumption of atheism and the epistemic justification of atheism.

According to current methodological orthodoxy philosophers rely on intuitions about thought experiments to refute general claims about the nature of knowledge, freedom, thought, reference, justice, beauty, etc. Philosophers working under the banner of ‘negative experimental philosophy’ have criticized more traditional philosophers for relying on this method. They argue that intuitions about thought experiments are influenced by factors that are irrelevant to the truth of their contents. Cappelen and Deutsch defend traditional philosophy against this critique by rejecting the picture of philosophical (...) methodology it presupposes: philosophers do not really rely on intuitions. In this paper, I defend methodological orthodoxy by arguing that philosophers must rely on intuitions somewhere and that they do in fact often rely on intuitions about thought experiments. I also argue in favor of a reply to the negative experimental critique that is similar to at least part of Deutsch’s own. (shrink)

In this article I argue that two received accounts of belief and assertion cannot both be correct, because they entail mutually contradictory claims about Moore's Paradox. The two accounts in question are, first, the Action Theory of Belief, the functionalist view that belief must be manifested in dispositions to act, and second, the Belief Account of Assertion, the Gricean view that an asserter must present himself as believing what he asserts. It is generally accepted also that Moorean assertions are absurd, (...) and that BAA explains why they are. I shall argue that ATB implies that some Moorean assertions are, in some fairly ordinary contexts, well justified. Thus BAA and ATB are mutually inconsistent. In the concluding section I explore three possible ways of responding to the dilemma, and what implications they have for the nature of the constitutive relationships linking belief, assent and behavioural dispositions.

Ideal epistemologists investigate the nature of pure epistemic rationality, abstracting away from human cognitive limitations. Non-ideal epistemologists investigate epistemic norms that are satisfiable by most humans, most of the time. Ideal epistemology faces a number of challenges, aimed at both its substantive commitments and its philosophical worth. This paper explains the relation between ideal and non-ideal epistemology, with the aim of justifying ideal epistemology. Its approach is meta-epistemological, focusing on the meaning and purpose of epistemic evaluations. I provide an account (...) on which the fundamental difference between ideal and non-ideal epistemic evaluations is that only the non-ideal epistemic ‘ought’ implies any substantive ‘can’. I argue that only ideal epistemic evaluations are ‘normatively robust’: they are neither conventional nor seriously context-sensitive. Non-ideal epistemic evaluations are normatively non-robust, exhibiting both conventionality and serious context-sensitivity from an interesting variety of distinct sources. For this reason, non-ideal epistemic evaluations won’t characterize the fundamental nature of epistemic rationality. Non-ideal epistemic rationality depends, not merely on what’s epistemically valuable, but also on modally contingent epistemic conventions and contextually contingent constraints on epistemic options. If we want a normatively robust theory of epistemic rationality, ideal epistemology is the only game in town. (shrink)

A common epistemological assumption in contemporary bioethics held b y both proponents and critics of non-traditional forms of cognitive enhancement is that cognitive enhancement aims at the facilitation of the accumulation of human knowledge. This paper does three central things. First, drawing from recent work in epistemology, a rival account of cognitive enhancement, framed in terms of the notion of cognitive achievement rather than knowledge, is proposed. Second, we outline and respond to an axiological objection to our proposal that draws (...) from recent work by Leon Kass (2004), Michael Sandel (2009), and John Harris (2011) to the effect that ‘enhanced’ cognitive achievements are (by effectively removing obstacles to success) not worthy of pursuit, or are otherwise ‘trivial’. Third, we show how the cognitive achievement account of cognitive enhancement proposed here fits snugly with recent active externalist approaches (e.g., extended cognition) in the philosophy of mind and cognitive science.

Intellectual autonomy has long been identified as an epistemic virtue, one that has been championed influentially by Kant, Hume and Emerson. Manifesting intellectual autonomy, at least, in a virtuous way, does not require that we form our beliefs in cognitive isolation. Rather, as Roberts and Wood note, intellectually virtuous autonomy involves reliance and outsourcing to an appropriate extent, while at the same time maintaining intellectual self-direction. In this essay, I want to investigate the ramifications for intellectual autonomy of a particular (...) kind of epistemic dependence: cognitive enhancement. Cognitive enhancements involve the use of technology and medicine to improve cognitive capacities in healthy individuals, through mechanisms ranging from smart drugs to brain-computer interfaces. With reference to case studies in bioethics, as well as the philosophy of mind and cognitive science, it is shown that epistemic dependence, in this extreme form, poses a prima facie threat to the retention of intellectual autonomy, specifically, by threatening to undermine our intellectual self-direction. My aim will be to show why certain kinds of cognitive enhancements are subject to this objection from self-direction, while others are not. Once this is established, we’ll see that even some extreme kinds of cognitive enhancement might be not merely compatible with, but constitutive of, virtuous intellectual autonomy. (shrink)
