In the paper, I distinguish the bottom-up strategy and the intentional stance strategy of analyzing group intentional states, and show that the thesis of distributed group subject of knowledge could be accommodated by either of them. Moreover, I argue that when combined with virtue reliabilism the thesis satisfactorily explains the phenomenon of group knowledge. To justify my argument, in the second part of the paper, I distinguish two accounts of justification pointing to conditions of group knowledge. The first, which I (...) call the belief-centered approach to group intentional states, determines the concept of group belief and group justificatory reason. The second, the process-centered approach represented by S. Orestis Palermos, employs the theory of virtue reliabilism and focuses on the group knowledge-conducive process. In the paper, I argue in favor of the latter as the internalism associated with the former appears to lack sufficient explanatory power. The theory of virtue epistemology runs into considerable difficulties when trying to deal with an extended epistemic subject composed of one individual and her cognitive artifact. In the two last parts of the paper, I consider the most important difficulties and argue that these obstacles are overcome once one adopts an approach combining virtue epistemology and the thesis of distributed group epistemic subject.

This paper discusses a set of observations, many of which are novel, concerning differences between the adjectival modals _certain_ and _possible_ and their adverbial counterparts _certainly_ and _possibly_. It argues that the observations can be derived from a standard interpretation of _certain_/_certainly_ as universal and _possible_/_possibly_ as existential quantifiers over possible worlds, in conjunction with the hypothesis that the adjectives quantify over knowledge and the adverbs quantify over belief. The claims on which the argument relies include the following: (i) knowledge (...) implies belief, (ii) agents have epistemic access to their belief, (iii) relevance is closed under speakers’ belief, and (iv) commitment is pragmatically inconsistent with explicit denial of belief.

At first sight one might be tempted to regard Descartes' "cogito ergo sum" as logically true by existential generalisation. This however would neither exhaust the specific epistemic content of "cogito" nor reveal the philosophical peculiarities of "sum" which the author takes to have two ontologically different meanings. The full sense of "cogito ergo sum" finally turns out to be "Credo* me* cogitare ergo scio* me* $\text{esse}_{1/2}$ ". Furthermore this proposition can formally be proved to be true by means of epistemic (...) logic. (shrink)

Sensitivity has sometimes been thought to be a highly epistemologically significant property, serving as a proxy for a kind of responsiveness to the facts that ensure that the truth of our beliefs isn’t just a lucky coincidence. But it's an imperfect proxy: there are various well-known cases in which sensitivity-based anti-luck conditions return the wrong verdicts. And as a result of these failures, contemporary theorists often dismiss such conditions out of hand. I show here, though, that a sensitivity-based understanding of (...) epistemic luck can be developed that respects what was attractive about sensitivity-based approaches in the first place but that's immune to these failures.

While it is well known that the early Heidegger distinguishes between different ‘kinds of being’ and identifies various ‘structures’ that compose them, there has been little discussion about what these kinds and structures of being are. This paper defends the ‘Property Thesis’, the position that kinds of being (and their structures) are properties of the entities that have them. I give two arguments for this thesis. The first is grounded in the fact that Heidegger refers to kinds and structures of (...) being as ‘characteristics’ and ‘determinations’, which are just two different words for ‘properties’, in the broadest senses of these terms. The second argument is based on the fact that kinds and structures of being play three roles that properties are supposed to play: they are what account for similarities between things, they are what predicates express, and they are what abstract nouns refer to.

In chapter four of Truth and Truthfulness Bernard Williams presents an account of assertion that relies heavily on the ‘psychological’ notions of belief and intention. In chapter five his definition of lying similarly relies on such notions. For Williams, insofar as there are norms governing assertion as such or norms broken by lying as such, these norms relate to saying what you think to be true, as distinct from saying what is true. I argue that this ‘psychologized’ account of assertion (...) (and lying) is for various reasons mistaken. A consequence of Williams’s approach is that ‘Shall I tell the truth here?’ is presented as a much more open question for an agent than it possibly can be. Only by adverting to the language-game presupposed by that question’s having any sense at all can we arrive at a fair picture of when and how the answer ‘No’ might be reasonable. (shrink)

We argue for a new mode of interpretation for attributed attitudes, what we call de translato interpretation. De translato interpretation assigns a meaning to an expression based on the interpretation given to that expression by the attitude subject rather than that standardly given by the attributor. We argue that this new mode of interpretation is distinct from but compatible with de dicto, de re and de qualitate interpretation. Formally, de translato interpretation is analyzed as introducing a modification in the language (...) used for interpretation, where the modification alters the attributor’s language in such a way as to more closely approximate the presumed language of a perspective holder. Attitude predicates are taken to introduce the perspective of their subject as a parameter of interpretation for the clause they embed. (shrink)

SummaryThe Gricean maxims of conversation are regulated by a supermaxim which determines what is relevant or not for a particular conversation. This maxim, involving a pragmatical knowledge, imposes specific restrictions on conversational strategy. It is called the “maxim of conversation topology” because it fixes the topos of a conversation.RésuméDans cet article nous démontrons que les maximes de la conversation, établies par H.P. Grice, sont dominées par une supermaxime qui détermine ce qui est pertinent et ce qui n'est pas pertinent pour (...) une certaine conversation. Cette maxime, qui implique une connaissance ?on;ordre pragmatique, impose des restrictions spécifiques sur la stratégie de conversation. Cette supermaxime, axiomatiquement premiére, est appelée ici la maxime de la topologie de la conversation, puisque c'est elle qui fixe le topos?on;une conversation.ZusammenfassungDie Maximen, die Grice für die Durchführung einer Konversation aufstellt, werden ihrerseits durch eine Obermaxime geregelt, die bestimmt, was für eine gegebene Konversation relevant ist oder nicht.

Sie wird die Maxime der Konversationstopologie genannt, weil sie den Topos einer Konversation festlegt. (shrink)

Epistemologists have known for two-and-a-half centuries that there are serious difficulties surroundingnon-demonstrativeinference. The best-known problem,theproblem of induction, was first diagnosed by Hume in theTreatise. In our own century, several more problems were added, e.g., by Hempel —the paradox of the ravens—and by Goodman —the “new,” or exacerbated, problem of induction. But an even greater blow lay ahead: within the decade after Goodman's problem appeared, Gettier was to publish his famous challenge to the traditional analysis of knowledge which, again, underscored how (...) problematic inductive inferences are.

In recent years, there has been increasing discussion of whether philosophy actually makes progress. This discussion has been prompted, in no small part, by the depth and persistence of disagreement among philosophers on virtually every major theoretical issue in the field. In this paper, I examine the role that the Method of Cases – the widespread philosophical method of testing and revising theories by comparing their verdicts against our intuitions in particular cases – plays in creating and sustaining theoretical disagreements (...) in philosophy. Drawing on work from cognitive psychology, I argue that there is a fundamental incompatibility between the structure of the theories that philosophers seek to construct using the MoC and the structure of the concepts on which our case-specific intuitions are based. This incompatibility renders MoC-based philosophical theorizing unable ever to succeed by the very standards of adequacy that it sets for itself. And this, in turn, helps to explain the depth and persistence of theoretical disagreements – and, in certain ways, the lack of progress – in the many areas of philosophy where the MoC plays an important role.

Sider (2011, 2013) proposes a reductive analysis of metaphysical modality—‘(modal) Humeanism’—and goes on to argue that it has interesting epistemological and methodological implications. In particular, Humeanism is supposed to undermine a class of ‘arguments from possibility’, which includes Sider's (1993) own argument against mereological nihilism and Chalmers's (1996) argument against physicalism. I argue that Sider's arguments do not go through, and moreover that we should instead expect Humeanism to be compatible with the practice of arguing from possibility in philosophy.

This article argues that justified true beliefs in Gettier cases often are not true due to luck. I offer two ‘unlucky’ Gettier cases, and it's easy enough to generate more. Hence even attaching a broad ‘anti‐luck’ codicil to the tripartite account of knowledge leaves the Gettier problem intact. Also, two related questions are addressed. First, if epistemic luck isn't distinctive of Gettier cases, what is? Second, what do Gettier cases reveal about knowledge?

Duncan Pritchard has argued that luck is fundamentally a modal notion: an event is lucky when it occurs in the actual world, but does not occur in more than half of the relevant nearby possible worlds. Jennifer Lackey has provided counterexamples to accounts which, like Pritchard’s, only allow for the existence of improbable lucky events. Neil Levy has responded to Lackey by offering a modal account of luck which attempts to respect the intuition that some lucky events occur in more (...) than half of the relevant nearby possible worlds. But his account rejects that events which are as likely as those in Lackey’s examples are lucky. Instead, they are merely fortunate. I argue that Levy’s argument to this effect fails. I then offer a substitute account of the improbability condition which respects this intuition. This condition says that the relevant notion of probability for luck is epistemic. (shrink)

Positions in the debate about the correct semantics of “S knows that p” are sometimes motivated in part by an appeal to interpretive charity. In particular, non-skeptical views hold that many utterances of the sentence “S knows that p” are true and some of them think the fact that their views are able to respect this is a reason why their views are more charitable than skeptical invariantism. However, little attention has been paid to why charity should be understood in (...) this way and little effort has been spent justifying the notion that a charitable semantics is likely to be true. I distinguish two kinds of interpretive charity. One principle of charity is often appealed to in the literature. I introduce a second. I argue that while some positions better respect one principle of charity, the reverse is true of the other principle of charity. I conclude with some remarks about how to break this apparent tie.

Perception is typically distinguished from cognition. For example, seeing is importantly different from believing. And while what one sees clearly influences what one thinks, it is debatable whether what one believes and otherwise thinks can influence, in some direct and non-trivial way, what one sees. The latter possible relation is the cognitive penetration of perception. Cognitive penetration, if it occurs, has implications for philosophy of science, epistemology, philosophy of mind, and cognitive science. This paper offers an analysis of the phenomenon, (...) its theoretical consequences, and a variety of experimental results and possible interpretations of them. The paper concludes by proposing some constraints for analyses and definitions of cognitive penetrability. (shrink)

In this paper we propose to argue for two claims. The first is that a sizeable group of epistemological projects – a group which includes much of what has been done in epistemology in the analytic tradition – would be seriously undermined if one or more of a cluster of empirical hypotheses about epistemic intuitions turns out to be true. The basis for this claim will be set out in Section 2. The second claim is that, while the jury is (...) still out, there is now a substantial body of evidence suggesting that some of those empirical hypotheses are true. Much of this evidence derives from an ongoing series of experimental studies of epistemic intuitions that we have been conducting. A preliminary report on these studies will be presented in Section 3. In light of these studies, we think it is incumbent on those who pursue the epistemological projects in question to either explain why the truth of the hypotheses does not undermine their projects, or to say why, in light of the evidence we will present, they nonetheless assume that the hypotheses are false. In Section 4, which is devoted to Objections and Replies, we’ll consider some of the ways in which defenders of the projects we are criticizing might reply to our challenge. Our goal, in all of this, is not to offer a conclusive argument demonstrating that the epistemological projects we will be criticizing are untenable. Rather, our aim is to shift the burden of argument. (shrink)

Many philosophers have argued that an event is lucky for an agent only if it was suitably improbable, but there is considerable disagreement about how to understand this improbability condition. This paper argues for a hitherto overlooked construal of the improbability condition in terms of the lucky agent’s epistemic situation. According to the proposed account, an event is lucky for an agent only if the agent was not in a position to know that the event would occur. It is also (...) explored whether this new account threatens the anti- luck program in epistemology. It is argued that although not detrimental to the anti- luck program, the epistemic account of luck sets certain important limits to its scope and feasibility. (shrink)

It has recently been argued that indeterminacy and indeterminism make most ordinary counterfactuals false. I argue that a plausible way to avoid such counterfactual skepticism is to postulate the existence of primitive modal facts that serve as truth-makers for counterfactual claims. Moreover, I defend a new theory of ‘might’ counterfactuals, and develop assertability and knowledge criteria to suit such unobservable ‘counterfacts’.

How do people decide which claims should be considered mere beliefs and which count as knowledge? Although little is known about how people attribute knowledge to others, philosophical debate about the nature of knowledge may provide a starting point. Traditionally, a belief that is both true and justified was thought to constitute knowledge. However, philosophers now agree that this account is inadequate, due largely to a class of counterexamples (termed ‘‘Gettier cases’’) in which a person’s justified belief is true, but (...) only due to luck. We report four experiments examining the effect of truth, justification, and ‘‘Gettiering’’ on people’s knowledge attributions. These experiments show that: (1) people attribute knowledge to others only when their beliefs are both true and justified; (2) in contrast to contemporary philosophers, people also attribute knowledge to others in Gettier situations; and (3) knowledge is not attributed in one class of Gettier cases, but only because the agent’s belief is based on ‘‘apparent’’ evidence. These findings suggest that the lay concept of knowledge is roughly consistent with the traditional account of knowledge as justified true belief, and also point to a major difference between the epistemic intuitions of laypeople and those of philosophers.

Artificial intelligence (AI) plays a rapidly increasing role in clinical care. Many of these systems, for instance, deep learning-based applications using multilayered Artificial Neural Nets, exhibit epistemic opacity in the sense that they preclude comprehensive human understanding. In consequence, voices from industry, policymakers, and research have suggested trust as an attitude for engaging with clinical AI systems. Yet, in the philosophical and ethical literature on medical AI, the notion of trust remains fiercely debated. Trust skeptics hold that talking about trust (...) in nonhuman agents constitutes a category error and worry about the concept being misused for ethics washing. Proponents of trust have responded to these worries from various angles, disentangling different concepts and aspects of trust in AI, potentially organized in layers or dimensions. Given the substantial disagreements across these accounts of trust and the important worries about ethics washing, we embrace a diverging strategy here. Instead of aiming for a positive definition of the elements and nature of trust in AI, we proceed ex negativo, that is we look at cases where trust or distrust are misplaced. Comparing these instances with trust expedited in doctor–patient relationships, we systematize these instances and propose a taxonomy of both misplaced trust and distrust. By inverting the perspective and focusing on negative examples, we develop an account that provides useful ethical constraints for decisions in clinical as well as regulatory contexts and that highlights how we should not engage with medical AI.

Academics across widely ranging disciplines all pursue knowledge, but they do so using vastly different methods. Do these academics therefore also have different ideas about when someone possesses knowledge? Recent experimental findings suggest that intuitions about when individuals have knowledge may vary across groups; in particular, the concept of knowledge espoused by the discipline of philosophy may not align with the concept held by laypeople. Across two studies, we investigate the concept of knowledge held by academics across seven disciplines (N (...) = 1,581) and compare these judgments to those of philosophers (N = 204) and laypeople (N = 336). We find that academics and laypeople share a similar concept of knowledge, while philosophers have a substantially different concept. These experiments show that (a) in contrast to philosophers, other academics and laypeople attribute knowledge to others in some “Gettier” situations; (b) academics and laypeople are much less likely to attribute knowledge when reminded of the possibility of error, but philosophers are not affected by this reminder; and (c) non‐philosophy academics are overall more skeptical about knowledge than laypeople or philosophers. These findings suggest that academics across a wide range of disciplines share a similar concept of knowledge, and that this concept aligns closely with the intuitions held by laypeople, and differs considerably from the concept of knowledge described in the philosophical literature, as well as the epistemic intuitions of philosophers themselves.

Recently, a number of philosophers have advanced a surprising conclusion: people's judgments about whether an agent brought about an outcome intentionally are pervasively influenced by normative considerations. In this paper, we investigate the ‘Chairman case’, an influential case from this literature and disagree with this conclusion. Using a statistical method called structural path modeling, we show that people's attributions of intentional action to an agent are driven not by normative assessments, but rather by attributions of underlying values and characterological dispositions (...) to the agent. In a second study, we examined people's judgments about what they think drives asymmetric intuitions in the Chairman case and found that people are highly inaccurate in identifying which features of the case their intuitions track. In the final part of the paper, we discuss how the statistical methods used in this study can help philosophers with the critical features problem, the problem of figuring out which among the myriad features present in hypothetical cases are the critical ones that our intuitions are responsive to. We show how the methods used in this study have some advantages over both armchair methods used by traditional philosophers and survey methods used by experimental philosophers. (shrink)

This paper attempts three things. The first is a defense and the rest is a critical appraisal of a crucial notion involved in the defense. First, it argues that John Turri’s criticisms of Ernest Sosa’s virtue epistemological account of knowledge that it fails to rule out Gettier cases rest on a misconstrual of the “because of clause” which Sosa employs. Turri overlooks the notion of “success manifests competence” which is central to understand the “because of” clause. Thus, the position of (...) Sosa is defended from the criticisms of Turri. Secondly, it critically examines the notion of “success manifests competence” which is a crucial notion in Sosa’s account. It argues, unlike what Sosa seems to hold, some of the conditions which Sosa provides for “success manifests competence” are not necessary. It also clarifies, by agreeing with Sosa, that the conditions he provides are not sufficient for “success manifests competence.” Thirdly, it briefly argues that Sosa’s occasional insistence that complete competence should be present in the case of success manifests competence brings in certain internal tension in the account of Sosa. Thus, the paper defends Sosa’s position from the criticisms of Turri; but it also clarifies Sosa’s account as well as raises some criticisms to it. (shrink)

The Meno problem, asking for the surplus value of knowledge beyond the value of true justified belief, was recently much treated within reliabilist and virtue epistemologies. The answers from formal epistemology, by contrast, are quite poor. This paper attempts to improve the score of formal epistemology by precisely explicating Timothy Williamson's suggestion that ‘present knowledge is less vulnerable than mere present true belief to rational undermining by future evidence’. It does so by combining Nozick's sensitivity analysis of knowledge with Spohn's (...) fact‐asserting epistemic interpretation of conditionals. Accordingly, the surplus value of knowledge lies in a specific kind of stability of knowledge, which differs, though, from that claimed by other so‐called stability analyses of knowledge. (shrink)

Among the results of recent investigation of epistemic intuitions by experimental philosophers is the finding that epistemic intuitions show cultural variability between subjects of Western, East Asian and Indian Sub-continent origins. In this paper I ask whether the finding of this variation is evidence of cross-cultural variation in the folk-epistemological competences that give rise to these intuitions—in particular whether there is evidence of variation in subjects’ explicit or implicit theories of knowledge. I argue that positing cross-cultural variation in subjects’ implicit (...) theories of knowledge is not the only possible explanation of the intuitions, and I suggest other explanations, including the hypothesis that each subject’s implicit theory of knowledge might contain a heterogeneous set of heuristics for ascribing knowledge. Variation in intuitions, then, might be the result of within-subject heterogeneity rather than across-subject heterogeneity. (shrink)

We investigate the interactions between scalar implicatures and presuppositions in sentences containing both a scalar item and presupposition trigger. We first critically discuss Gajewski and Sharvit’s previous approach. We then closely examine two ways of integrating an exhaustivity-based theory of scalar implicatures with a trivalent approach to presuppositions. The empirical side of our discussion focuses on two novel observations: the interactions between prosody and monotonicity, and what we call presupposed ignorance. In order to account for these observations, our final proposal (...) relies on two mechanisms of scalar strengthening, the Presupposed Ignorance Principle and an exhaustivity operator which lets the presuppositions of negated alternatives project.

This paper explores some consequences of Lewis’s (Australas J Philos 74(4):549–567, 1996) understanding of how knowledge is compartmentalized. It argues, first, that he underestimates how badly it impacts his view. When knowledge is compartmentalized, it lacks at least one of two essential features of Lewis’s account: (a) Elusiveness—familiar skeptical possibilities, when relevant, are incompatible with everyday knowledge. (b) Knowledge is a modality—when a thinker knows that p, there is no relevant possibility where p is false. Lewis proposes compartmentalized knowledge to (...) keep treating knowledge as a modality while mitigating one of its unrealistic epistemological implications: In normal modal epistemic logic (and standard possible world semantics), a thinker always counts as knowing the strongest proposition that follows from the set of all the individual propositions that this thinker knows. Lewis’s compartmentalization proposal is that thinkers merely know the conjunctions of propositions that are known in each of, but not across, their compartments. The irony is that in avoiding overblown knowledge the view now allows for thinkers to attend to skeptical error possibilities and yet knowledge is present. The account avoids inflation of knowledge in one sense only to acquire another type of knowledge the view denies subjects can have. This problem motivates an inspection of knowledge accounts whose intra-compartment closure principles are weaker than those that are valid in normal modal-logic. The conclusion is that some formulations of closure can avoid the challenge Lewis’s view faces. Nevertheless, even these closure principles pose a barrier—perhaps an implausible barrier—for knowledge of ignorance. Even when the reasoning supporting the lack of knowledge is sound, a subject cannot always know she doesn’t know. Interestingly, this obstacle is one that knowledge of knowledge doesn’t seem to face.

Many take the claim that you cannot ‘get’ an ‘ought’ from an ‘is’ to imply that non- moral beliefs are by themselves incapable of justifying moral beliefs. I argue that this is a mistake and that the position that moral beliefs are justified exclusively by non-moral beliefs—a view that I call moral inferentialism—presents an attractive non-sceptical moral epistemology.

The received definition of knowledge (as true, evident belief) has recently been questioned by Edmund Gettier with an example whose principle is as follows. A proposition, p, is both evident to and accepted by someone S, who sees that its truth entails (would entail) (that either p is true or q is true). This last is thereby made evident to him, and he accepts it, but it happens to be true only because q is true, since p is in fact (...) false. Hence, inasmuch as he has no evidence for the proposition q, S can hardly be said to know (that either p is true or q is true). Here then is a formula for true, evident beliefs that are not cases of knowledge. I discuss the possibility of adding a fourth condition to this triad. (shrink)

Contemporary experimental philosophers sometimes use versions of an argument from the history of philosophy to defend the claim that what they do is philosophy. Although experimental philosophers conduct surveys and carry out what appear to be experiments in psychology, making them methodologically different from most analytic philosophers working today, techniques like theirs were not out of the ordinary in the philosophy of the past, early modern philosophy in particular. Or so some of them argue. This paper disputes the argument, citing (...) important differences between early modern philosopher-scientists – Descartes, Hobbes and Boyle – and their supposed modern counterparts. Although there is some continuity between early modern philosopher-scientists and the contemporary experimentalists, it is mostly a continuity of interest in empirically informed philosophy, not a distinctively experimental philosophy.

What do you get when you cross a fallacy with a good argument? A fugu, that is, a valid argument that tempts you to reach its conclusion invalidly. You have yielded to the temptation more than you realize. If you are a teacher, you may have served many fugus. They arise systematically through several mechanisms. Fugus are interesting intermediate cases that shed light on the following issues: bare evidentialism, false pleasure, philosophy of education, and the ethics of argument. Normally, a (...) fugu will not yield knowledge from known premises. But if the reasoning is only slightly fallacious, they do yield knowledge. These mild fugus show that we can gain knowledge by invalid reasoning. This is a conservative resource for historians. They want to credit discoveries to Euclid rather than those who made minor corrections to his proofs, such as David Hilbert. We also benefit from this practice of grandfathering in old standards of knowledge attribution. For we can compete spiritedly for priority. We do not need to worry that credit will instead go to future scholars who will make the minor amendments needed to raise present proofs to a future standard of demonstration. (shrink)

I extract, and then analyse critically, the epistemological ideas that are implicit in Robin DiAngelo's best-selling book White Fragility and her other writings.

In this paper we present a semantic analysis of the application of didactic constructivism to chemical education. We show that the psychological basis of constructivism yield, when applied to chemistry, an internalist semantics for the chemical names. Since these names have been presented as typical examples of an externalism for kind terms, a fundamental incompatibility ensues. We study this situation, to conclude that it affects chemical education at every level. Finally, we present a preliminary analysis of this problem from the (...) point of view of physics. (shrink)

This article treats religion as a central concern in Whitehead. His view of rational religion relies primarily on rational inference, not direct intuition. Taking seriously in religion the nonreflective elements in human cognition would not jeopardize, but would strengthen, his treatment of the reflective ones. While religion can certainly include vestiges of human savagery, it also promotes the ascent of humanity beyond social decay and enhances the art of life.

Traditional epistemology is often said to have reached an impasse, and recent interest in virtue epistemology supposedly marks a turn away from philosophers’ traditional focus on problems of knowledge and truth. Yet that focus re-emerges, especially among ‘reliabilist’ virtue epistemologists. I argue for a more ‘responsibilist’ approach and for the importance of some of the quieter and gentler epistemic virtues, by contrast with the tough-minded ones that are currently popular in education. In particular I make a case for what I (...) here call ‘unknowing’: a positive state that is not the same as ignorance. I acknowledge the mystical connotations of the term, and suggest that there is a strong interest in unknowing in writers such as Plato, Kierkegaard and Nietzsche. In their style of philosophising they also address the paradox of being knowing about unknowingness itself. (shrink)

In this paper, I critically discuss one of the more influential arguments for mereological universalism, what I will call ‘the Vagueness Argument’. I argue that a premise of the Vagueness Argument is not well supported and that there are at least two good reasons for thinking that the premise in question is false.

We propose a new topological semantics for evidence, evidence-based justifications, belief, and knowledge. Resting on the assumption that an agent’s rational belief is based on the available evidence, we try to unveil the concrete relationship between an agent’s evidence, belief, and knowledge via a rich formal framework afforded by topologically interpreted modal logics. We prove soundness, completeness, decidability, and the finite model property for the associated logics, and apply this setting to analyze key epistemological issues such as “no false lemma” (...) Gettier examples, misleading defeaters, undefeated justification versus undefeated belief, as well as the defeasibility theories of knowledge. (shrink)

Why is it that philosophers find it so hard to come to agreement? Many disputes that have gone on for centuries or even millennia are still unresolved, even though there has been increased conceptual sophistication on the part of the contending parties. Consider, for example, the question of free will, where libertarians still contest the field with determinists and compatibilists.

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.
