This paper explicates Descartes’ theory of intuition (intuitus). Departing from certain commentators, I argue that intuition, for Descartes, is a form of clear and distinct intellectual perception. Because it is clear and distinct, it is indubitable, infallible, and provides a grade of certain knowledge he calls ‘cognitio’. I pay special attention to why he treats intuition as a form of perception, and what he means when he says it is ‘clear and distinct’. Finally, I situate his view in relation to (...) those of his Scholastic predecessors on one hand and current theories on the other. His view anticipates the contemporary ‘perceptual model of intuition’, though it is much bolder with its promise of certainty. (shrink)

The role intellectual virtues play in scientific inquiry has raised significant discussions in the recent literature. A number of authors have recently explored the link between virtue epistemology and philosophy of science with the aim to show whether epistemic virtues can contribute to the resolution of the problem of theory choice. This paper analyses how intellectual virtues can be beneficial for successful resolution of theory choice. We explore the role of virtues as well as vices in scientific inquiry and their (...) beneficial effects in the context of theory choice. We argue that vices can play a role in widening the set of potential candidate theories and support our claim with historical examples and normative arguments from formal social epistemology. We argue that even though virtues appear to be neither necessary nor sufficient for scientific success, they have a positive effect because they accelerate successful convergence amongst scientists in theory choice situations.

Mathematicians do not claim to know a proposition unless they think they possess a proof of it. For all their confidence in the truth of a proposition with weighty non-deductive support, they maintain that, strictly speaking, the proposition remains unknown until such time as someone has proved it. This article challenges this conception of knowledge, which is quasi-universal within mathematics. We present four arguments to the effect that non-deductive evidence can yield knowledge of a mathematical proposition. We also show that (...) some of what mathematicians take to be deductive knowledge is in fact non-deductive. 1 Introduction2 Why It Might Matter3 Two Further Examples and Preliminaries4 An Exclusive Epistemic Virtue of Proof?5 Analyses of Knowledge6 The Inductive Basis of Deduction7 Physical to Mathematical Linkages8 Conclusion.

A utility-based approach to the understanding of vague predicates (VPs) is proposed. It is argued that assignment of truth values to propositions containing VPs entails unjustifiable assumptions of consensus; two models of VP semantics are criticized on this basis: (1) the super-truth theory of Kit Fine (1975), which requires an unlikely consensus on base points; (2) the fuzzy logic of Lotfi Zadeh (1975), on fuzzy truth values of sentences. Pragmatism is held to provide a key: successful behavior justifies a person's (...) knowledge of the content of a VP. Instead of attempting to determine a consensus underlying successful communication, the utility of individual communications is held to rest on sufficient approximation of meanings between people. 3 Figures, 17 References.

We propose a model for belief which is free of presuppositions. Current models for belief suffer from two difficulties. One is the well known problem of logical omniscience which tends to follow from most models. But a more important one is the fact that most models do not even attempt to answer the question what it means for someone to believe something, and just what it is that is believed. We provide a flexible model which allows us to give meaning (...) to beliefs in general contexts, including the context of animal belief , and of human belief which is expressed in language.

In this paper I aim to illuminate the significance of thought insertion for debates about the first-person concept. My starting point is the often-voiced contention that thought insertion might challenge the thesis that introspection-based self-ascriptions of psychological properties are immune to error through misidentification relative to the first-person concept. In the first part of the paper I explain what a thought insertion-based counterexample to this immunity thesis should be like. I then argue that various thought insertion-involving scenarios do not give (...) rise to successful counterexamples to the immunity of the target class of self-ascriptions. In the second part of the paper I turn to defend a Metasemantic Explanation of why the immunity thesis holds. The Metasemantic Explanation rests on a reference-fixing story about the mental ‘I’ whose key contention is that introspective impressions play an essential role in fixing its reference. It is part of my argument in favour of the proposed reference-fixing story, as well as of the Metasemantic Explanation, that they respect the paradigmatic features of self-ascriptions of inserted thoughts.

Dualism in the Epistemology of Testimony and the Ability Intuition Content Type Journal Article DOI 10.1007/s11406-010-9291-4 Authors Spyridon Orestis Palermos, Department of Philosophy, School of Philosophy, Psychology and Language Sciences (PPLS), The University of Edinburgh, Edinburgh, UK Journal Philosophia Online ISSN 1574-9274 Print ISSN 0048-3893.

Frankfurt-Style Cases (FSCs) seem to elicit the intuitive judgment that an agent is morally responsible despite being unable to act otherwise, which is supposed to falsify the Principle of Alternative Possibility (PAP). Recent empirical studies have shown that the inclination toward this intuitive judgment is shared among people, which seems to reinforce the argument against the PAP. However, some scholars have argued for Descriptive Anti-Intuitionism (DAI) — intuitive judgments have never played an evidential role in philosophy — and thus denied (...) the philosophical significance of such empirical findings. I point out that although DAI fails in its literal claim for FSCs, an associated insight remains potent: an intuitive judgment is so fragile that it can be easily defeated by further arguments. Nevertheless, I argue, empirical studies are significant in uncovering the general principles to which we are committed in our practice concerning moral responsibility. I clarify how such findings can play a robust evidential role in philosophical debates concerning moral responsibility by tracing the literature written by Frankfurt and philosophers. (shrink)

Epistemologists often remark that knowledge precludes luck. A true belief based on a guess or hunch is not knowledge because it seems merely fortuitous, too much of an accident, and, well, lucky that one happened to get things right. Of course, true beliefs based on guesses and hunches are not justified. However, Gettier cases have persuasively shown that even justified true beliefs can admit knowledge‐precluding kinds of luck. So in what sense are justified true beliefs that don’t amount knowledge lucky (...) or ‘true only by chance’? I will address three different approaches to epistemic luck that have received significant attention in the recent literature: reliability approaches to epistemic luck, credit approaches to epistemic luck, and responsibilist or control approaches to epistemic luck. I will then turn my attention to the implications that epistemic luck has for other epistemic states. I will focus particularly on state of understanding and examine whether, and to what extent, understanding is vulnerable to epistemic luck. (shrink)

In this paper, I discuss two influential pictures of communication and the relation between them. One picture holds that successful communication requires identity of content: The speaker has a belief that she expresses with her utterance, and the hearer acquires a belief with the same content by understanding the utterance. The second picture was proposed by Lewis in his classic work Convention and then refined in “Languages and Language.” It sees communication as coordination among speakers—a technical notion that Lewis draws (...) from game theory. Samuel Cumming has recently provided an elegant and insightful synthesis of the two pictures, arguing that Lewisian coordination among speakers is in fact a form of content identity. In this paper, my negative goal is to argue against Cumming’s attempt to construe coordination as content identity, showing that it yields incorrect predictions about certain cases of successful communication. My positive goal is to show how we can avoid Cumming’s problematic interpretation of coordination and still do justice to the relevant data within a coordination-based framework. (shrink)

‘Motion’ in the acquisition of knowledge is the focus of this paper. My claim is that the motion in the acquisition of knowledge, albeit abstract, is of two dimensions: one as ‘the mind working towards reality’ and the other as ‘reality walking towards the mind’. Using an epistemic approach, I conceptualize these two dimensions (hereafter as the working and walking narrative) under the Externalism and the Internalism divide and identify that externalism leaves us with more to explore about knowledge acquisition (...) than internalism. Since externalism seems to accommodate the two dimensions better than internalism, I present the working and walking narrative under externalism. Two envisaged objections are addressed, along with considerations of some probable implications of the working and walking narrative for philosophy, specifically epistemology. (shrink)

Epistemologists have generally accepted that competently deduced, known conclusions must issue from known premises, as the principle of Counter-Closure demands; however, some have recently challenged the notion, arguing that knowledge may be inferred from non-knowledge. In this paper, I focus on the yet unexamined topic of inferential knowledge from Gettiered belief with regard to Greco's virtue-epistemic framework, which he refers to as ‘agent reliabilism’. I argue that agent reliabilism allows for instances of Counter-Closure violation. In presenting my argument, I construct (...) and provide an analysis of a case that challenges Counter-Closure, and defend the case against various possible objections, including some that feature in mainstream Counter-Closure literature. I contend that, if my analysis is accepted, Greco is left with two options: either he rejects Counter-Closure, or he must substantially revise his view in such a way as to preserve Counter-Closure in light of cases of inferential knowledge from Gettiered belief.

In Delusions and Beliefs, Kengo Miyazono proposes an extended and convincing argument for the thesis that delusions are malfunctional beliefs. One of the key assumptions for this argument is that belief is a biological notion, and that the function of beliefs is a product of evolution. I challenge the thesis that evolutionary accounts can furnish an epistemologically satisfying account of beliefs because evolutionary success does not necessarily track epistemic success. Consequently, also delusions as beliefs cannot be explained in a satisfactory (...) manner by looking at beliefs’ evolutionary function. How can we then salvage the notion of delusions as epistemologically relevant malfunctioning beliefs? I propose that knowledge-first epistemology gives us a way out. Knowledge-first accounts argue that knowledge is more primitive than belief. That is, knowledge is not a kind of successful beliefs ; instead, beliefs are failed attempts at knowledge. Being a belief derives from the norms of knowledge. Explaining the epistemology of beliefs through the primitive norms of knowledge, we can also explain why delusions are malfunctional beliefs: The cognitive and psychological defects that produce delusions block the beliefs from becoming knowledge. Consequently, delusions are attempts at knowledge that have failed particularly badly. (shrink)

There is a general presumption that epistemology does not have anything to do with wellbeing. In this paper I challenge these assumption, by examining the aftermath of the Gettier examples, the debate between internalism and externalism and the rise of virtue epistemology. In focusing on the epistemic agent as the locus of normativity, virtue epistemology allows one to ask questions about epistemic goods and their relationship to other kinds of good, including the good of the agent. Specifically it is argued (...) that emotion has a positive role to play in epistemology, an example from Aquinas is used to illustrate this and to illustrate the different kinds of good involved in cognition.

This paper defends the usefulness of the concept of philosophical progress and the common assumption that philosophy and science aim to make the same, or a comparable, kind of progress. It does so by responding to Yafeng Shan's (2022) arguments that the wealth of research on scientific progress is not applicable or useful to philosophy, and that philosophy doesn't need a concept of progress at all. It is ultimately argued that while Shan's arguments are not successful, they reveal the way (...) forward in developing accounts of philosophical progress. (shrink)

Many philosophers and psychologists hold that intuitions are, or reduce to, beliefs. The argument from intuition without beliefs threatens to undercut any such doxastic account: since there are clear cases of intuition without belief, intuitions cannot be beliefs. Advocates of the intellectual seeming account conclude that intuitions belong to the basic mental kind of intellectual seeming. I argue that rightly understood, apparent cases of intuition without belief are cases of someone having the inclination to believe that p whilst believing that (...) not-p. These can be accommodated by a disjunctive doxastic account holding that to have an intuition is to either have a belief, or to have an inclination to believe. I conclude that intuitions reduce to beliefs, and that there is no need to acknowledge intellectual seemings as basic states in our mental taxonomy. (shrink)

Self-knowledge is knowledge of one’s own states (or processes) in an indexical mode of presentation. The philosophical debate is concentrating on mental states (or processes). If we characterize self-knowledge by natural language sentences, the most adequate utterance has a structure like “I know that I am in mental state M”. This common sense characterization has to be developed into an adequate description. In this investigation we will tackle two questions: (i) What precisely is the phenomenon referred to by “self-knowledge” and (...) how can we adequately describe a form of self-knowledge which we might realistically enjoy? (ii) Can we have self-knowledge given the fact that the meaning of some words which we utter depends on the environment or the speech community? The theory we defend argues that we have to distinguish the public meaning of utterances, on the one hand, and the mental representations which are constituting a mental state of an individual, on the other. Self-knowledge should be characterized on the level of mental representations while the semantics of utterances self-attributing mental states should be treated separately. Externalism is only true for the public meaning of utterances but not for beliefs and other mental states including self-knowledge. (shrink)

A skeptic claims that I do not have knowledge of the external world. It has been thought that the skeptic reaches this conclusion because she employs unusually stringent standards for knowledge. But the skeptic does not employ unusually high standards for knowledge. Rather, she employs unusually restrictive standards of evidence. Thus, her claim that we lack knowledge of the external world is supported by considerations that would equally support the claim that we lack evidence for our beliefs about the external (...) world. These considerations do not threaten the truth of our ordinary attributions of evidence, however, for such attributions are context‐sensitive in their semantics.It is argued that this solution to the problem of the external world enjoys all of the benefits. and suffers none of the problems, of other solutions to the problem of the external world.

The basic claim of this paper consists of the following primary idea: Contrary to what is believed, neither experiences form a firm and certain basis for beliefs, nor experiences are in need of beliefs to be known.

Jim buys a ticket in a million-ticket lottery. He knows it is a fair lottery, but, given the odds, he believes he will lose. When the winning ticket is chosen, it is not his.

Further, if he knew his ticket would lose, then, given that his ticket is no different in its chances (...) of winning from any other ticket, it seems that by parity of reasoning he should also know that every other ticket would lose. But of course he doesn’t know that; in fact, he knows that not every ticket will lose. (shrink)

According to robust versions of virtue epistemology, the reason why knowledge is incompatible with certain kinds of luck is that justified true beliefs must be achieved by the agent . In a recent set of papers, Pritchard has challenged these sorts of views, advancing different arguments against them. I confront one of them here, which is constructed upon scenarios affected by environmental luck, such as the fake barn cases. My objection to Pritchard differs from those offered until now by Carter (...) , Jarvis or Littlejohn in that it is based on the claim that cognitive performances may not be properly considered as achievements beyond the scope of the agent’s intentional action—an idea that confers more explanatory power on my argument, and contributes to stregthening links between knowledge and agency.

We are witnessing a certain tendency in epistemology to account for the anti-luck intuition in terms of risk. I.e., instead of the traditional anti-luck diagnosis of Gettier cases and fake barn cases, a new anti-risk diagnosis seems to be preferable by many. My goal in this paper is twofold: first, I contribute to motivate that drift; and second, I defend that we ought to partially resist it. An anti-risk diagnosis is valid and preferable for fake barn cases, but we still (...) need an anti-luck diagnosis for classic Gettier cases. The paper thus defends the Solomon-like result that we need both concepts—epistemic luck and epistemic risk—to deal with all the cases where knowledge is undermined. (shrink)

Ethical challenges to certain aspects of research on human subjects are not uncommon; examples include challenges to first-in-human trials (Chapman in J Clin Res Bioethics 2(4):1–8, 2011), certain placebo controlled trials (Anderson in J Med Philos 31:65–81, 2006; Anderson and Kimmelman in Kennedy Inst Ethics J 20(1):75–98, 2010) and “sham” surgery (Macklin in N Engl J Med 341:992–996, 1999). To date, however, there are few challenges to research when the subjects are competent and the research is more than minimal risk (...) with no promise of direct benefit. The principal reason given for allowing research that is more than minimal risk without benefit is that we should respect the autonomy of competent subjects. I argue that though the moral intuitions informing respect for autonomy are sound, there is another set of intuitions regarding what we take to be just treatment of another when one agent knowingly causes or allows suffering on another agent. I argue that concerns generated by commutative justice serve as limitations on permissible research. I highlight our intuitions informing this notion of justice by appealing to work done on theodicy; what counts as a morally sufficient reason for God to allow suffering in humans is applicable also to the researcher-subject relationship. I conclude that all human subjects who are exposed to more than minimal risk research should enjoy the same actual protections (e.g., subpart D) as those given subjects who cannot consent. (shrink)

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

Many epistemologists use intuitive responses to particular cases as evidence for their theories. Recently, experimental philosophers have challenged the evidential value of intuitions, suggesting that our responses to particular cases are unstable, inconsistent with the responses of the untrained, and swayed by factors such as ethnicity and gender. This paper presents evidence that neither gender nor ethnicity influence epistemic intuitions, and that the standard responses to Gettier cases and the like are widely shared. It argues that epistemic intuitions are produced (...) by the natural ‘mindreading’ capacity that underpins ordinary attributions of belief and knowledge in everyday social interaction. Although this capacity is fallible, its weaknesses are similar to the weaknesses of natural capacities such as sensory perception. Experimentalists who do not wish to be skeptical about ordinary empirical methods have no good reason to be skeptical about epistemic intuitions. (shrink)

We naturally evaluate the beliefs of others, sometimes by deliberate calculation, and sometimes in a more immediate fashion. Epistemic intuitions are immediate assessments arising when someone’s condition appears to fall on one side or the other of some significant divide in epistemology.

Linguists and psychologists also study epistemic assessments; (...) the last section of the paper discusses some of their research and its potential relevance to epistemology. (shrink)

Recent work in experimental philosophy has indicated that intuitions may be subject to several forms of bias, thereby casting doubt on the viability of intuition as an evidential source in philosophy. A common reply to these findings is the ‘expertise defense’ – the claim that although biases may be found in the intuitions of non-philosophers, persons with expertise in philosophy will be resistant to these biases. Much debate over the expertise defense has centered over the question of the burden of (...) proof; must defenders of expertise provide empirical evidence of its existence, or should we grant the existence of philosophical expertise as a ‘default’ assumption? Defenders have frequently appealed to analogy with other fields; since expertise clearly exists in, e.g., the sciences, we are entitled to assume its existence in philosophy. Recently, however, experimentalists have begun to provide empirical evidence that biases in intuition extend even to philosophers. Though these findings don't yet suffice to defeat the default assumption of expertise the analogy argument motivates, they do force any proponent of the analogy argument to provide more specific and empirically informed proposals for the possible nature of philosophical expertise.

Max Deutsch’s new book argues against the commonly held ‘myth’ that philosophical methodology characteristically employs intuitions as evidence. While I am sympathetic to the general claim that philosophical methodology has been grossly oversimplified in the intuition literature, the particular claim that it is a myth that philosophers rely on intuitions as evidence is open to several very different interpretations. The plausibility and consequences of a rejection of the ‘myth’ will depend on the notion of evidence one employs, the notion of (...) intuition one holds, and how one understands the idea of ‘relying on’ or ‘employing’ something as evidence. I describe what I take to be the version of The Myth which is most plausibly undermined by Deutsch’s arguments; however, I also argue that the falsity of this myth has only minimal consequences for the viability of the experimental philosophy research project.

In this paper, I respond to Philip Atkins’ reply to my attempt to explain why Gettier cases (and Gettier-style cases) are misleading. I have argued that Gettier cases (and Gettier-style cases) are misdealing because the candidates for knowledge in such cases contain ambiguous designators. Atkins denies that Gettier’s original cases contain ambiguous designators and offers his intuition that the subjects in Gettier’s original cases do not know. I argue that his reply amounts to mere intuition mongering and I explain why (...) Gettier cases, even Atkins’ revised version of Gettier’s Case I, still contain ambiguous designators. (shrink)

This paper develops a precise understanding of the thesis of moral encroachment, which states that the epistemic status of an opinion can depend on its moral features. In addition, I raise objections to existing accounts of moral encroachment. For instance, many accounts fail to give sufficient attention to moral encroachment on credences. Also, many accounts focus on moral features that fail to support standard analogies between pragmatic and moral encroachment. Throughout the paper, I discuss racial profiling as a case study, (...) arguing that moral encroachment can help us identify one respect in which racial profiling is epistemically problematic.

This paper investigates a limitation of the model of belief and knowledge prevailing in mainstream economics, namely the state-space model. Because of its set-theoretic nature, this model has difficulties in capturing the difference between expressions that designate the same object but have different meanings, i.e., expressions with the same extension but different intensions. This limitation generates puzzling results concerning what individuals believe or know about the world as well as what individuals believe or know about what other individuals believe or (...) know about the world. The paper connects these puzzling results to two issues that are relevant for economic theory beyond the state-space model, namely, framing effects and the distinction between the model-maker and agents that appear in the model. Finally, the paper discusses three possible solutions to the limitations of the state-space model, and concludes that the two alternatives that appear practicable also have significant drawbacks.

This paper argues that just as full beliefs can constitute knowledge, so can properties of your credence distribution. The resulting notion of probabilistic knowledge helps us give a natural account of knowledge ascriptions embedding language of subjective uncertainty, and a simple diagnosis of probabilistic analogs of Gettier cases. Just like propositional knowledge, probabilistic knowledge is factive, safe, and sensitive. And it helps us build knowledge-based norms of action without accepting implausible semantic assumptions or endorsing the claim that knowledge is interest-relative.

In the following essay I set out the core argument expounded by Nicholas Rescher in regard of the link between reality and appearance, illustrating this argument based on chapter 6 of his Reality and its Appearance. Rescher’s argument overlaps with critical realist concerns based on his approach to metaphysical realism. I make the point that the argument exhibits the virtue of concision, but, as a result, suffers from under-elaboration in important areas; most particularly, an explicit engagement with standard philosophical problems (...) of appearance, such as Gettier, and, more generally, the fundamental issue of how appearance may or may not change in response to changes in the human condition.

Algunos de los más relevantes filósofos del derecho de los últimos años, como Carlos S. Nino y Ronald Dworkin, han defendido que hay una pluralidad de conceptos de Derecho. Scott Shapiro ha sostenido una posición especialmente relevante acerca de ello: la palabra ‘Derecho’ es sistemáticamente ambigua, pues a veces designa un conjunto de normas y otras veces una organización social. Esta es precisamente la tesis criticada en el trabajo. Se argumenta, basándose en determinada literatura filosófica acerca de los conceptos, que (...) los conceptos de objetos sociales de carácter intencional contienen una dimensión social y una dimensión significativa, normativa en el caso del derecho. El mismo concepto de Derecho expresa una dimensión social y una normativa imbricadas entre sí. Some of the most relevant legal philosophers in the last decades, as Carlos S. Nino and Ronald Dworkin, have defended the idea that there is a plurality of concepts of law. Scott Shapiro has sustained this account in a particularly relevant way: the word ‘law’ displays a ubiquitous ambiguity, sometimes designates a set of norms and other a social organization. This is precisely the thesis which is criticized in the paper. It is argued, from a certain philosophical literature about the concepts, that concepts of social objects of intentional character contain a social dimension and a meaning dimension, normative in the case of the law. That is to say, the concept of law expresses a social dimension and a normative dimension intertwined. (shrink)

Fred Dretske's "Knowledge and the Flow of Information" is an extended attempt to develop a philosophically useful theory of information. Dretske adapts central ideas from Shannon and Weaver's mathematical theory of communication, and applies them to some traditional problems in epistemology. In doing so, he succeeds in building for philosophers a much-needed bridge to important work in cognitive science. The pay-off for epistemologists is that Dretske promises a way out of a long-standing impasse -- the Gettier problem. He offers an (...) alternative model of knowledge as information-based belief, which purports to avoid the problems justificatory accounts face. This essay looks closely at Dretske's theory. I argue that while the information-theoretic framework is attractive, it does not provide an adequate account of knowledge. And there seems to be no way of tightening the theory without introducing some version of a theory of justification -- the very notion Dretske's theory was designed to avoid. (shrink)

Traditional epistemology of knowledge and belief can be succinctly characterized as JTB-epistemology, i.e., it is characterized by the thesis that knowledge is justified true belief. Since Gettier’s trail-blazing paper of 1963 this account has become under heavy attack. The aim of is paper is to study the Gettier problem and related issues in the framework of topological epistemic logic. It is shown that in the framework of topological epistemic logic Gettier situations necessarily occur for most topological models of knowledge and (...) belief. On the other hand, there exists a special class of topological models (based on so called nodec spaces) for which traditional JTB-epistemology is valid. Further, it is shown that for each topological model of Stalnaker’s combined logic KB of knowledge and belief a canonical JTB-model (its JTB-doppelganger) can be constructed that shares many structural properties with the original model but is free of Gettier situations. The topological model and its JTB-doppelganger both share the same justified belief operator and have very similar knowledge operators. Seen from a somewhat different perspective, the JTB-account of epistemology amounts to a simplification of a more general epistemological account of knowledge and belief that assumes that these two concepts may differ in some cases. The JTB-account of knowledge and belief assumes that the epistemic agent’s cognitive powers are rather large. Thereby in the JTB-epistemology Gettier cases do not occur. Eventually, it is shown that for all topological models of Stalnaker’s KB- logic Gettier situations are topologically characterized as nowhere dense situations. This entails that Gettier situations are epistemologically invisible in the sense that they can neither be known nor believed with justification with respect to the knowledge operator and the belief operator of the models involved.

It is plausible to think that the epistemic benefit of having an explanation is understanding. My focus in this article is on the extent to which explanatory understanding, perhaps unlike knowledge, is compatible with certain forms of luck—the extent to which one can understand why something is the case when one is lucky to truly believe an explanatorily relevant proposition. I argue, contra Stephen Grimm ([2006]) and Duncan Pritchard ([2008], [2009]), that understanding quite generally is compatible with luckily believing a (...) true, explanatorily relevant proposition. My strategy is to argue that various intuitions that seem to rule against lucky understanding can be explained away, and thus do not compel us to reject the thesis that, in general, understanding tolerates luck. In arriving at this conclusion, I address some salient issues regarding the testimony of others, and also draw out the consequences of my discussions for the status of understanding as a cognitive achievement.

Qualia Epiphenomenalism is the view that qualitative events lack causal efficacy. A common objection to qualia epiphenomenalism is the so-called Self-Stultifying Objection, which suggests that justified, true belief about qualitative events requires, among other things, the belief to be caused by the qualitative event—the very premise that qualia epiphenomenalism denies. William Robinson provides the most sustained response to the self-stultification objection that is available. In this paper I argue that Robinson's reply does not sufficiently overcome the self-stultification objection.

According to orthodox views of philosophical methodology, when philosophers appeal to intuitions, they treat them as evidence for their contents. Call this “descriptive evidentialism.” Descriptive evidentialism is assumed both by those who defend the epistemic status of intuitions and by those, including many experimental philosophers, who criticize it. This article shows, however, that the idea that philosophers treat intuitions as evidence struggles to account for the way philosophers treat intuitions in a variety of philosophical contexts. In particular, it cannot account (...) for philosophers' treatment of a priori intuitions, for nonpropositional uses of intuition, and for philosophers' failure to use intuition to exclude the counterintuitive. The article concludes that alternatives to descriptive evidentialism (some of which are sketched) must be developed, and that much of the recent debate between traditionalists and skeptics from, for example, experimental philosophy is probably based on a false presupposition.

According to the eligibility theory of meaning, often attributed to David Lewis, the referent of a predicate is the property that best balances the twin constraints of charity and eligibility, where eligibility is a function of metaphysical naturalness. This sort of metasemantics, which is motivated by its ability to resolve problems of indeterminacy and secure shared reference between disputing parties, can be somewhat friendly towards revisionary theories, since highly natural properties can act as “reference magnets,” securing our reference despite some (...) mismatch with usage. In this paper, I apply these considerations to normative ethics and argue that the theory of rule utilitarianism achieves a high balance of charity and eligibility. I proceed by comparing rule utilitarianism to two of its well-known rivals, act utilitarianism and Rossian pluralism. I show how the former achieves a high degree of eligibility but only at a significant cost of charity, while the latter does the opposite, fitting very nicely with our considered judgments but at the price of very low eligibility. Rule utilitarianism, on the other hand, strikes a good balance between these extremes; it assigns to our core moral term a relatively natural property without doing too much damage to our moral convictions. Thus, rule utilitarianism should be regarded as a promising moral theory by any philosopher who takes seriously considerations of eligibility and naturalness. (shrink)

Has the theory of rationality as ‘openness to criticism’ solved the problem of ‘rational belief in reason’? This is the main question the present article intends to address. I respond to this question by arguing that the justified true belief account of knowledge has prevented Karl Popper’s critical and William Bartley’s pan-critical rationalism from solving the problem of rational belief in reason. To elaborate this response, the article presents its arguments in three stages: First, it argues that the idea of (...) objective knowledge as justified true belief leads to the equation of objective knowledge with justification. Hence, if we base the theory of critical rationalism, as openness to criticism, upon such a conception of knowledge, our theory of rationality involves in infinite regress of proofs. Second, it argues that Popper describes critical rationalism as an ‘irrational attitude’ of openness to criticism because the rationalist cannot justify his belief in reason by argument or experience. Thus, since Popper assumes that ‘a belief in reason’ must be justified in order to be ‘rational’ he cannot lead to a solution for the problem of rational belief in reason. Third, it argues that, like Popper’s critical rationalism, Bartley’s pan-critical rationalism originates in the justified true belief account of knowledge, however, not because Bartley defines critical rationalism as irrational faith in reason, but because his theory does not tell us how an ‘open’ belief in reason is to be refuted logically. The reason for this failure is that Bartley uses Popper’s epistemology of science to define the conception of criticism. While Popper and Bartley are recognized as the non-justificationist philosophers of science and rationality, this article tries to reveal that the idea of objective knowledge as justified true belief has prevented them from showing how ‘a rational belief in reason’ can be defended by argument. The article also briefly shows the consequence of this study for a notable change in the logical foundations of science. (shrink)

In this paper, I argue that, as far as Gettier cases are concerned, appearances are deceiving. That is, Gettier cases merely appear to be cases of epistemic failure (i.e., failing to know that p) but are in fact cases of semantic failure (i.e., failing to refer to x). Gettier cases are cases of reference failure because the candidates for knowledge in these cases contain ambiguous designators. If this is correct, then we may simply be mistaking semantic facts for epistemic facts (...) when we consider Gettier cases. This, in turn, is a good reason not to assign much, if any, evidential weight to Gettier intuitions (i.e., that S doesn’t know that p in a Gettier case). (shrink)

In this paper, I argue that, just as the problem of unconceived alternatives provides a basis for a New Induction on the History of Science to the effect that a realist view of science is unwarranted, the problem of unconceived objections provides a basis for a New Induction on the History of Philosophy to the effect that a realist view of philosophy is unwarranted. I raise this problem not only for skepticism’s sake but also for the sake of making a (...) point about philosophical argumentation, namely, that anticipating objections to one’s claim is not the same as supporting one’s claim. In other words, defending p from objections does not amount to support or evidence for p. This, in turn, presents dialectical and pragma-dialectical approaches to argumentation with the following question: does proper argumentation require that arguers anticipate and respond to unconceived objections?

In this paper, we present what we call the argument from accidental truth, according to which some instances of deflationist schemata, even those carefully reformulated and adjusted by Field and Horwich to accommodate the truth of utterances, are falsified due to accidental truths. Since the folk concept of truth allows for accidental truths, the deflationary theory of truth will face a serious problem. In particular, it follows that the deflationist schema fails to capture the proper extension of truth by precluding (...) accidental truths of utterances. Even though the argument uses the contextualist cases, this conclusion does not require so much as the truth of contextualism, but only two assumptions, the existence of context-relative non-literal contents of utterances (or speech acts), and the existence of accidental truths, both of which are widely accepted by folks and theorists. We will also consider various responses to the argument, including the revisionary deflationist position, all of which we argue are unsatisfactory or committed to a highly implausible view. (shrink)

I have argued that Gettier cases are misleading because, even though they appear to be cases of knowledge failure, they are in fact cases of semantic failure. Atkins has responded to my original paper and I have replied to his response. He has then responded again to insist that he has the so-called “Gettier intuition.” But he now admits that intuitions are only defeasible, not conclusive, evidence for and/or against philosophical theories. I address the implications of Atkins’ admission in this (...) paper and I again show that his attempts to revise Gettier’s original cases such that they do not involve semantic failures are unsuccessful.
