Jonathan Ichikawa (2012) argues that the standard counterexamples to the knowledge norm of practical reasoning are no such thing. More precisely, he argues that those alleged counterexamples rest on claims about which actions are appropriate rather than on claims about which propositions can be appropriately treated as reasons for action. Since the knowledge norm of practical reasoning concerns the latter and not the former, Ichikawa contends that proponents of the alleged counterexamples must offer a theory that bridges the gap between (...) the two types of claims. I argue, first, that the standard counterexamples do not rest on claims about which actions are appropriate, second, that even if they did, we would not need a theory to bridge the gap between the two types of claims, and, third, that even if we did need such a theory, a plausible theory is on offer.

My aim in this article is to investigate the epistemic dimension of reasonableness. In the last decades, the concept of reasonableness has been deeply analysed, and yet, I maintain that a strictly epistemic analysis of reasonableness is still lacking. The goal of this article is to clarify which epistemic features characterize reasonableness as one of the fundamental virtues in the political domain. In order to justify political liberalism through a public justification that averts the risk of falling into a dilemma, (...) it is important to establish in advance which are the epistemic constraints that should be respected. My proposal is that a moderate approach in moral epistemology expresses the best scheme available to us – as moral agents constrained by the limit of our rationality – for establishing a normatively binding, and yet realistic, procedure of justification for political institutions and practices.

According to Williamson, your evidence consists of all and only what you know (E = K). According to his critics, it doesn’t. While E = K calls for revision, the revisions it calls for are minor. E = K gets this much right. Only true propositions can constitute evidence and anything you know non-inferentially is part of your evidence. In this paper, I defend these two theses about evidence and its possession from Williamson’s critics who think we should break more (...) radically from E = K. (shrink)

The paper surveys the currently available axiomatizations of common belief (CB) and common knowledge (CK) by means of modal propositional logics. (Throughout, knowledge- whether individual or common- is defined as true belief.) Section 1 introduces the formal method of axiomatization followed by epistemic logicians, especially the syntax-semantics distinction, and the notion of a soundness and completeness theorem. Section 2 explains the syntactical concepts, while briefly discussing their motivations. Two standard semantic constructions, Kripke structures and neighbourhood structures, are introduced in Sections (...) 3 and 4, respectively. It is recalled that Aumann's partitional model of CK is a particular case of a definition in terms of Kripke structures. The paper also restates the well-known fact that Kripke structures can be regarded as particular cases of neighbourhood structures. Section 3 reviews the soundness and completeness theorems proved w.r.t. the former structures by Fagin, Halpern, Moses and Vardi, as well as related results by Lismont. Section 4 reviews the corresponding theorems derived w.r.t. the latter structures by Lismont and Mongin. A general conclusion of the paper is that the axiomatization of CB does not require as strong systems of individual belief as was originally thought- only monotonicity has thusfar proved indispensable. Section 5 explains another consequence of general relevance: despite the "infinitary" nature of CB, the axiom systems of this paper admit of effective decision procedures, i.e., they are decidable in the logician's sense.

This paper concerns the extent to which uncertain propositional reasoning can track probabilistic reasoning, and addresses kinematic problems that extend the familiar Lottery paradox. An acceptance rule assigns to each Bayesian credal state p a propositional belief revision method B p , which specifies an initial belief state B p (T) that is revised to the new propositional belief state B(E) upon receipt of information E. An acceptance rule tracks Bayesian conditioning when B p (E) = B p|E (T), for (...) every E such that p(E) > 0; namely, when acceptance by propositional belief revision equals Bayesian conditioning followed by acceptance. Standard proposals for uncertain acceptance and belief revision do not track Bayesian conditioning. The "Lockean" rule that accepts propositions above a probability threshold is subject to the familiar lottery paradox (Kyburg 1961), and we show that it is also subject to new and more stubborn paradoxes when the tracking property is taken into account. Moreover, we show that the familiar AGM approach to belief revision (Harper, Synthese 30(1-2):221-262, 1975; Alchourrón et al., J Symb Log 50:510-530, 1985) cannot be realized in a sensible way by any uncertain acceptance rule that tracks Bayesian conditioning. Finally, we present a plausible, alternative approach that tracks Bayesian conditioning and avoids all of the paradoxes. It combines an odds-based acceptance rule proposed originally by Levi (1996) with a non-AGM belief revision method proposed originally by Shoham (1987). (shrink)

Radical experimentalists argue that we should give up using intuitions as evidence in philosophy. In this paper, I first argue that the studies presented by the radical experimentalists in fact suggest that some intuitions are reliable. I next consider and reject a different way of handling the radical experimentalists' challenge, what I call the Argument from Robust Intuitions. I then propose a way of understanding why some intuitions can be unreliable and how intuitions can conflict, and I argue that on (...) this understanding, both moderate experimentalism and the standard philosophical practice of using intuitions as evidence can help resolve these conflicts.

In the past two decades, epistemologists have significantly expanded the focus of their field. To the traditional question that has dominated the debate — under what conditions does belief amount to knowledge? — they have added questions about testimony, epistemic virtues and vices, epistemic trust, and more. This broadening of the range of epistemic concern has coincided with an expansion in conceptions of epistemic agency beyond the individualism characteristic of most earlier epistemology. We believe that these developments have not gone (...) far enough. While the weak anti-individualism we see in contemporary epistemology may be adequate for the kinds of cases it tends to focus on, a great deal of human knowledge production and transmission does not conform to these models. Furthermore, the dispositions and norms that are knowledge-conducive in the familiar cases may not be knowledge-conducive generally. In fact, dispositions that, at an individual level, count as epistemic vices may be epistemic virtues in common social contexts. We argue that this overlooked feature of human social life means that epistemology must become more deeply and pervasively social. (shrink)

Contemporary process metaphysics has achieved a number of important results, most significantly in accounting for emergence, a problem on which substance metaphysics has foundered since Plato. It also faces trenchant problems of its own, among them the related problems of boundaries and individuation. Historically, the quest for ontology may thus have been largely responsible for the persistence of substance metaphysics. But as Plato was well aware, an ontology of substantial things raises serious, perhaps insurmountable problems for any account of our (...) epistemic access to such things. Physical things are subject to change, and as such, they are poor objects of knowledge—if knowledge is to be more reliable than mere opinion. There is a reading of Plato’s Theaetetus on which knowledge may be understood as a relation between an epistemic subject and a logos, where logoi are intrinsically dialectical, and where dialectic is a kind of intersubjective activity. Insofar as this epistemology may be attributed to Plato, the project of this paper is Platonic in spirit. It is also, in a sense, Kantian, in that it divorces ontology from the search for things-in-themselves, redirecting our attention from things to objects: epistemic objects. Such objects can be understood, as Maurice Merleau-Ponty proposed, as shared by multiple subjects by virtue of their participation in an intersubjective world, constituted by what Shaun Gallagher calls participatory sense-making. On an epistemology constructed in this way, the fact that both epistemic objects and their subject are mutable is no obstacle to knowledge. Far-from-equilibrium systems are forever mutable; at thermodynamic equilibrium, there would be neither subject, nor object. Epistemic objects, on this picture, are metastable loci of interactive potential. (shrink)

Penelope Maddy's original solution to the dilemma posed by Benacerraf in his 'Mathematical Truth' was to reconcile mathematical empiricism with mathematical realism by arguing that we can perceive realistically construed sets. Though her hypothesis has attracted considerable critical attention, much of it, in my view, misses the point. In this paper I vigorously defend Maddy's account against published criticisms, not because I think it is true, but because these criticisms have functioned to obscure a more fundamental issue that is well (...) worth addressing: in general -- and not only in the mathematical domain -- empiricism and realism simply cannot be reconciled by means of an account of perception anything like Maddy's. But because Maddy's account of perception is so plausible, this conclusion raises the specter of the broader incompatibility of realism and empiricism, which contemporary philosophers are frequently at pains to forget.

SummaryIn this paper I will strive towards three main objectives. First of all, I will try to show that a very commonplace property of knowledge, that of yielding truth, can be used to characterize an ideal and radical notion of knowledge. It will be argued that this property generates a basic and autonomous concept of knowledge, i.e., a purely logical concept of knowledge that can be clearly separated from the psychological, intentional or epistemological aspects of knowledge. What results can thus (...) be regarded as a kind of reduction of the concept of knowledge to that of truth. This reduction will be expressed by means of a criterion which a relation between an agent and a sentence must satisfy in order to be interpreted as exemplifying the relation of knowing.Secondly, 1 will offer an analysis of presuppositional knowledge which shows how the very strong and ideal notion of knowledge previously developed can be useful in interpreting the ordinary use of “knowing”.My third and last objective will be to use this criterion to characterize formally the semantic interpretation associated to a rational and competent agent, i.e. the space of his knowledge.

I generalize the notion of a conditional attitude by bringing together two topics of inquiry. One is the ordinary inquiry into conditional attitudes. The other topic is the inquiry into the attitude of thinking that a proposition is likely, or having a high credence in a proposition. For instance, what is it to intend to go to the game if it is likely that Kershaw pitches? Being likely that Kershaw pitches is the condition of the attitude. Given a natural position (...) about statements like “It is likely that Kershaw pitches,” the target attitude looks different from ordinary conditional attitudes. (shrink)

The numerous modal systems between S4 and S5 are investigated from an epistemological point of view by interpreting necessity either as knowledge or as (strong) belief. It is shown that-granted some assumptions about epistemic logic for which the author has argued elsewhere-the system S4.4 may be interpreted as the logic of true belief, while S4.3.2 and S4.2 may be taken to represent epistemic logic systems for individuals who accept the scheme knowledge = true belief only for certain special instances. There (...) is strong evidence in favor of the assumption that S4.2 is the logic of knowledge. (shrink)

ABSTRACTIn this paper, I offer an account of propositional learning: namely, learning that p. I argue for what I call the “Three Transitions Thesis” or “TTT” according to which four states and three transitions between them characterize such learning. I later supplement the TTT to account for learning why p. In making my case, I discuss mathematical propositions such as Fermat's Last Theorem and the ABC Conjecture, and then generalize to other mathematical propositions and to non-mathematical propositions. I also discuss (...) some interesting applications of the TTT, and reply to some noteworthy objections. (shrink)

Antognazza (“The Benefit to Philosophy”, “The Distinction in Kind”), Dutant (“The Legend”), and I (“Knowledge Before Gettier”) have argued for the historical falsity of the claim that, prior to Gettier’s famous counterexamples of sixty years ago, the so-called ‘traditional’ conception of knowledge was the justified true belief (JTB) conception. This note addresses a related historical question that, rather surprisingly, has not yet been addressed in the philosophical literature; to wit: when did this claim first appear in this literature?

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance.

The paper identifies a distinctive feature of friendship. Friendship, it is argued, is a relationship between two people in which each participant values the other and successfully communicates this fact to the other. This feature of friendship, it is claimed, explains why friendship plays a key role in human happiness, why it is praised by philosophers, poets, and novelists, and why we all seek friends. Although the characterization of friendship proposed here differs from other views in the literature, it is (...) shown that it accommodates key insights of other writers on the topic. Thus, in accordance with the Aristotelian strategy the paper employs, it is shown that the account on offer preserves the received opinions on friendship. (shrink)

Traditional epistemological reflection on our beliefs about the world attempts to proceed without presupposing or ineliminably depending upon any claims about the world. It has been argued that epistemological externalism fails to engage in the right way with the motivations for this project. I argue, however, that epistemological externalism satisfyingly undermines this project. If we accept the thesis that certain conditions other than the truth of one's belief must obtain in the world outside of one's mind in order for one (...) to have knowledge (or justified belief) about the world, then there is no good intellectual motivation for taking up the traditional project. This results stands even if we accept the traditional theses that knowledge requires justified belief and that justified belief requires the ability to provide good reasons for one's belief.

There is an objection to coherence theories of knowledge to the effect that coherence is not connected with truth, so that when coherence leads to truth this is just a matter of luck. Coherence theories embrace falliblism, to be sure, but that does not sustain the objection. Coherence is connected with truth by principles of justified acceptance that explain the connection between coherence and truth. Coherence is connected with truth by explanatory principle, not just luck.

To resolve the lottery paradox, the “no-justification account” proposes that one is not justified in believing that one's lottery ticket is a loser. The no-justification account commits to what I call “the Harman-style skepticism”. In reply, proponents of the no-justification account typically downplay the Harman-style skepticism. In this paper, I argue that the no-justification reply to the Harman-style skepticism is untenable. Moreover, I argue that the no-justification account is epistemically ad hoc. My arguments are based on a rather surprising finding (...) that the no-justification account implies that people living in Taiwan typically suffer from the Harman-style skepticism. (shrink)

Recent literature has seen a surging interest in the modal principle involved in the Gettier-style thought experiments. According to the necessitation thesis, the modal principle underlying the Gettier-style thought experiments takes the form of a principle of necessitation. It is widely agreed that the necessitation thesis is seriously threatened by the problem of deviant realizations. Based on the Gricean pragmatic theory of communication, I defend the necessitation thesis against the problem of deviant realizations. The present account bears some significant similarities (...) to Pierre Saint-Germier’s account. After comparing and contrasting these two accounts, I argue that the differences between them actually speak in favor of the present account over Saint-Germier’s one. (shrink)

In this paper we address the question of how it can be possible for a non-expert to acquire justified true belief from expert testimony. We discuss reductionism and epistemic trust as theoretical approaches to answer this question and present a novel solution that avoids major problems of both theoretical options: Performative Expert Testimony (PET). PET draws on a functional account of expertise insofar as it takes the expert’s visibility as a good informant capable to satisfy informational needs as equally important (...) as her specific skills and knowledge. We explain how PET generates justification for testimonial belief, which is at once assessable for non-experts and maintains the division of epistemic labor between them and the experts. Thereafter we defend PET against two objections. First, we point out that the non-expert’s interest in acquiring widely assertable true beliefs and the expert’s interest in maintaining her status as a good informant counterbalances the relativist account of justification at work in PET. Second, we show that with regard to the interests at work in testimonial exchanges between experts and non-experts, PET yields a better explanation of knowledge-acquisition from expert testimony than externalist accounts of justification such as reliabilism. As our arguments ground in a conception of knowledge, which conceives of belief-justification as a declarative speech act, throughout the rearmost sections of this paper we also indicate to how such a conception is operationalized in PET.

According to Lehrer’s defeasibility account of knowledge, we can understand knowledge as undefeated justified true belief. But this account faces many serious problems. One important problem is that from one’s subjective point of view, one can hardly bridge the gap between one’s personal justification and objective truth. Another important problem is that this account can hardly accommodate the externalist intuition that the epistemic status of a belief is not entirely determined by factors that are internal to the subject’s perspective. The (...) goal of this paper is to offer an alternative account of knowledge which can successfully deal with these problems. On the basis of a Sellarsian social practice theory of justification, I argue that we can understand knowledge as objectively justified belief. (shrink)

Robert Brandom argues for a “pragmatic phenomenalist account” of knowledge. On this account, we should understand our notion of justification in accordance with a Sellarsian social practice model, and there is nothing more to the phenomenon of knowledge than the proprieties of takings-as-knowing. I agree with these two claims. But Brandom's proposal is so sketchy that it is unclear how it can deal with a number of much-discussed problems in contemporary epistemology. The main purpose of this article is to develop (...) and defend a pragmatic phenomenalist account of knowledge by resolving those problems. I argue, in particular, that this account can accommodate both the lesson of the Gettier problem and the lesson of reliabilism simultaneously. -/- RÉSUMÉ: Robert Brandom soutient une «théorie pragmatique et phénomenaliste» de la connaissance.

Je suis tout à fait d'accord avec ces deux opinions. Mais la thèse de Brandom est si sommaire qu'il n'est pas évident de savoir comment elle peut trailer les nombreux problèmes discutés en épistémologie contemporaine.

In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the three premises she releases ideal theorists (...) from the paradox, which is as follows. (1) Any sound theory of justice is action-guiding. (2) Any sound theory of justice is ideal. (3) Any ideal theory fails to be action-guiding. Here I shall respond to Valentini in two ways. First, I shall show that both (1) and (2) are false. The falsity of either is sufficient to release ideal theorists from the paradox. Second, I shall show that Valentini’s response to (3) can be extended, because her bad kinds of ideal theory do not necessarily fail to guide action. The cumulative effect of my arguments further strengthens Valentini’s support of ideal theory. I will deal with premises (1) and (2) in Sections I and II, and (3) in Section III. (shrink)

This paper deals with the COVID 19 pandemic problems from the point of view of political epistemology. It analyses the validity of conspiracy theories related to the origin, existence, and premeditation of COVID 19, as well as the effectiveness and legitimacy of the vaccines developed to stop its advance. To this end, the development of the work focuses on what we call the problem of the "formulation" that underlies conspiracy theories, analyzing it in two related dimensions. The first dimension of (...) an epistemic nature provides a demarcation criterion for the rationality of theories based on the falsification criterion. The second dimension accentuates a political aspect analyzed from the standard of the reasonableness of such views. Both factors point out that conspiracy theories around the pandemic leave the world aside, whether in terms of the empirical basis that supports it or the democratic public space necessary for its development deliberation. From this approach, these views result in irrational and unreasonable ones to different degrees. (shrink)

The assumption that philosophers rely on intuitions to justify their philosophical positions has recently come under substantial criticism. In order to protect philosophy from experimental findings that suggest that intuitions are epistemically problematic, a number of metaphilosophers have argued that intuitions play no substantial epistemic role in philosophy. This paper focuses on attempts to deny intuitions’ epistemic role through exegetical analysis of original thought experiments. Using Deutsch’s particularly well-developed exegesis of Gettier’s 10 coin case as an exemplar of this method, (...) I examine the challenges the strategy faces. I argue that intuition denial fails to provide a satisfactory account of how verdicts of thought experiments are justified. Instead, it commits intuition deniers to the conclusion that the arguments of Gettier, Kripke, Thomson, and others are bad arguments. As a result, rather than defusing challenges to the case method raised by experimental philosophers, intuition denial ultimately leads to the same troubling conclusion – that philosophers hold their positions on bad grounds.

This paper argues that we should distinguish two different kinds of imaginative vividness: vividness of mental images and vividness of imaginative experiences. Philosophy has focussed on mental images, but distinguishing more complex vivid imaginative experiences from vivid mental images can help us understand our intuitions concerning the notion as well as the explanatory power of vividness. In particular, it can help us understand the epistemic role imagination can play on the one hand and our emotional engagement with literary fiction on (...) the other hand. (shrink)

In recent years, two competing methodological frameworks have developed in the study of the epistemology of philosophy. The traditional camp, led by experimental philosophy and its allies, has made inferences about the epistemology of philosophy based on the reactions, or intuitions, people have to works of philosophy. In contrast, multiple authors have followed the lead of Deutsch and Cappelen by setting aside experimental data in favor of inferences based on careful examination of the text of notable works of philosophy. In (...) other words, the debate is split between authors focusing on philosophy’sconsumptionand those focusing on philosophy’sproduction. This paper examines the motivation for focusing on original texts and other evidence of philosophy’s production and finds it lacking. Drawing upon Hills’ distinction between propagation and transmission, I argue that the social epistemology of philosophy does not justify the recent focus on original texts of philosophy. Because the philosophical knowledge of consumers of philosophy is likelyinspiredby producers of philosophy, as opposed to epistemically grounded in the producers’ epistemic states, experimental philosophy had it right all along—if we want to know the epistemic standing of philosophy, we need to look to philosophy’s consumers.

What is it to have conclusive reasons to believe a proposition P? According to a view famously defended by Dretske, a reason R is conclusive for P just in case [R would not be the case unless P were the case]. I argue that, while knowing that P is plausibly related to having conclusive reasons to believe that P, having such reasons cannot be understood in terms of the truth of this counterfactual condition. Simple examples show that it is possible (...) to believe P on the basis of reasons that satisfy the counterfactual, and still get things right about P only as a matter of luck. Seeing where this account of conclusive reasons goes wrong points to an important distinction between having conclusive reasons and relying on reasons that are in point of fact conclusive. It also has wider consequences for whether modal principles like sensitivity and safety can rule out the pernicious kind of epistemic luck, or the kind of luck that interferes with knowledge.

A view of knowledge—what I call the "Deserving Credit View of Knowledge" —found in much of the recent epistemological literature, particularly among so-called virtue epistemologists, centres around the thesis that knowledge is something for which a subject deserves credit. Indeed, this is said to be the central difference between those true beliefs that qualify as knowledge and those that are true merely by luck—the former, unlike the latter, are achievements of the subject and are thereby creditable to her. Moreover, it (...) is often further noted that deserving credit is what explains the additional value that knowledge has over merely lucky true belief. In this paper, I argue that the general conception of knowledge found in the DCVK is fundamentally incorrect. In particular, I show that deserving credit cannot be what distinguishes knowledge from merely lucky true belief since knowledge is not something for which a subject always deserves credit. (shrink)

One of the central problems afflicting reductionism in the epistemology of testimony is the apparent fact that infants and small children are not cognitively capable of having the inductively based positive reasons required by this view. Since non-reductionism does not impose a requirement of this sort, it is thought to avoid this problem and is therefore taken to have a significant advantage over reductionism. In this paper, however, I argue that if this objection undermines reductionism, then a variant of it (...) similarly undermines non-reductionism. Thus, considerations about the cognitive capacities of infants and small children do not effectively discriminate between these two competing theories of testimonial justification. (shrink)

It is widely assumed that memory has only the capacity to preserve epistemic features that have been generated by other sources. Specifically, if S knows (justifiedly believes/rationally believes) that p via memory at T2, then it is argued that (i) S must have known (justifiedly believed/rationally believed) that p when it was originally acquired at Tl, and (ii) S must have acquired knowledge that p (justification with respect to p/rationality with respect to p) at Tl via a non-memorial source. Thus, (...) according to this view, memory cannot make an unknown proposition known, an unjustified belief justified, or an irrational belief rational--it can only preserve what is already known, justified, or rational. In this paper, I argue that condition (i) is false and, a fortiori, that condition (ii) is false. Hence, I show that, contrary to received wisdom in contemporary epistemology, memory can function as a generative epistemic source. (shrink)

There is a widely accepted family of views in the epistemology of testimony centering around the claim that belief is the central item involved in a testimonial exchange. For instance, in describing the process of learning via testimony, Elizabeth Fricker provides the following: “one language-user has a belief, which gives rise to an utterance by him; as a result of observing this utterance another user of the same language, his audience, comes to share that belief.” In a similar spirit, Alvin (...) Plantinga says that “…a belief on the part of the testifiee has warrant only if that belief has warrant for the testifier.” In both of these passages, we find strands of what I shall call the Belief View of Testimony.

The Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and (...) a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus. (shrink)

There is a great divide between two approaches to epistemology over the past thirty to forty years. Some label the divide that between internalists and externalists, and that characterization may be accurate on some account of the distinction. I will pursue the divide from a different direction, in part because the literature on the distinction between internalism and externalism has become a mess, and I don’t want to clean up the mess here.

This paper addresses the definition and the operational use of intuitions in philosophical methods in the form of a research study encompassing several regions of the globe, involving 282 philosophers from a wide array of academic backgrounds and areas of specialisation. The authors tested whether philosophers agree on the conceptual definition and the operational use of intuitions, and investigated whether specific demographic variables and philosophical specialisation influence how philosophers define and use intuitions. The results obtained point to a number of (...) significant findings, including that philosophers distinguish between intuitions used to formulate (discovery) and to test (justification) philosophical theory. The survey results suggest that strategies implemented to characterise philosophical intuition are not well motivated since, even though philosophers do not agree on a single account of intuition, they fail to capture a preferred usage of intuitions as aspects of discovery. The quantitative summary of survey findings informs the debate on this topic, and advances more defined routes for subsequent approaches to the study of intuitions. (shrink)

In this article, the epistemological interpretation of the relationship between concepts of relativism, beliefs, and probability ensures a defense of two theses, namely, (i) epistemic relativism refers to attitudes that depend on the repetition and anchoring of probabilistic beliefs, and (ii) Popper’s propensity interpretation of probability discloses the connections between relativity, probability, and collective subjectivity. The propensity interpretation brings a framework for describing the role of collective subjectivity in epistemic systems. This approach, as an acceptable epistemological stance, is related to (...) the variability of anchored collective beliefs. The repetition and anchoring of subjective probabilistic beliefs becomes a relative reference frame for evaluating the elements of knowledge. With this in mind, each particular way of considering probability indicates a manner of distinguishing epistemic systems. In epistemic systems, the statements are collective points of view expressed in the form ‘p is justified when belief in p is probably reliable.’ The statements can be accurate in a particular epistemic system but inaccurate in other systems. As a result, by avoiding the ‘all statements must be true or false’ requirement, each proponent of a certain epistemic system can build a probabilistic picture of the world. In this picture, not every statement needs to be ‘true’ when and if the statement expresses a collective point of view that has a propensity to be reliable and justified. (shrink)

A series of representations must be semantics-driven if the members of that series are to combine into a single thought: where semantics is not operative, there is at most a series of disjoint representations that add up to nothing true or false, and therefore do not constitute a thought at all. A consequence is that there is necessarily a gulf between simulating thought, on the one hand, and actually thinking, on the other. A related point is that a popular doctrine (...) - the so-called 'computational theory of mind' (CTM) - is based on a confusion. CTM is the view that thought-processes consist in 'computations', where a computation is defined as a 'form-driven' operation on symbols. The expression 'form-driven operation' is ambiguous, as it may refer either to syntax-driven operations or to morphology-driven operations. Syntax-driven operations presuppose the existence of operations that are driven by semantic and extra-semantic knowledge. So CTM is false if the terms 'computation' and 'form-driven operation' are taken to refer to syntax-driven operations. Thus, if CTM is to work, those expressions must be taken to refer to morphology-driven operations. CTM therefore fails, given that an operation must be semantics-driven if it is to qualify as a thought. CTM therefore fails on each possible disambiguation of the expressions 'formal operation' and 'computation,' and it is therefore false. (shrink)

In the current debate there are two epistemological approaches to the definition of ignorance. The Standard View defines ignorance simply as not knowing, while the New View defines it as the absence of true belief. We argue that both views provide necessary, but not sufficient conditions for ignorance, and thus do not constitute satisfactory definitions for such a notion.

Epistemologie a kognitivní věda se zabývají studiem procesů poznání. Z výsledků takového bádání vyplývají určité diagnostické a preskriptivní závěry s cílem pozitivně regulovat způsob myšlení. Předložená práce má za cíl ukázat, že epistemické a kognitivní studie nejsou doposud dostatečně vyvinuté, aby mohly kategoricky doporučit správný a universální způsob myšlení. Pokrok ve vědě je výsledek kolektivního úsilí nejen současnosti, ale i minulých objevů a omylů. Na historickém případě chybné teorie flogistonu se tato práce bude snažit doložit, že se na objevení pravdy (...) plodně podílí i nesprávné epistemické procesy. Tendence některých myslitelů dneška takové praktiky morálně odsuzovat na základě prevalence pseudovědeckých názorů je málo produktivní. Podrobné studium dynamiky chybující minulosti osvětlí poznávací proces lépe než soubor sterilních epistemických pravidel. (shrink)

It has often been thought that our knowledge of ourselves is _different_ from, perhaps in some sense _better_ than, our knowledge of things other than ourselves. Indeed, there is a thriving research area in epistemology dedicated to seeking an account of self-knowledge that would articulate and explain its difference from, and superiority over, other knowledge. Such an account would thus illuminate the descriptive and normative difference between self-knowledge and other knowledge.¹ At the same time, self- knowledge has also encountered its (...) share of skeptics – philosophers who refuse to accord it any descriptive, let alone normative, distinction. In this paper, we argue that there is at least one _species_ of self-knowledge that is different from, and better than, other knowledge. It is a specific kind of knowledge of one’s concurrent phenomenal experiences. Call knowledge of one’s own phenomenal experiences _phenomenal knowledge_. Our claim is that some (though not all) phenomenal knowledge is different from, and better than, non-phenomenal knowledge. In other. (shrink)
