The Proper Functionist account of warrant – like many otherexternalist accounts – is vulnerable to certain Gettier-style counterexamples involving accidentally true beliefs. In this paper, I briefly survey the development of the account, noting the way it was altered in response to such counterexamples. I then argue that Alvin Plantinga's latest amendment to the account is flawed insofar as it rules out cases of true beliefs which do intuitively strike us as knowledge, and that a conjecture recently put forward by (...) Thomas Crisp is also defective. I conclude by presenting my own suggestion as to how the account can be made less vulnerable to counterexamples involving accidentally true beliefs. Although I stay within the confines of Proper Functionism here, I think that my proposal (modulo a few details) could be attached to other externalist accounts of warrant as well. -/- . (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. (shrink)

I begin with an explication of "thought experiment". I then clarify the role that intuitions play in thought experiments by addressing two important issues: (1) the informativeness of thought experiments and (2) the legitimacy of the method of thought experiments in philosophy and the natural sciences. I defend a naturalistic account of intuitions that provides a plausible explanation of the informativeness of thought experiments, which, in turn, allows thought experiments to be reconstructed as arguments. I also specify criteria for distinguishing (...) bad "intuition pumps" from legitimate thought experiments. These criteria help us to avoid being seduced by the dangerous suggestive power of misleading intuitions. (shrink)

No one has done more than John Martin Fischer and Mark Ravizza to advance our understanding of the important dispute in the theory of responsibility between structuralists and historicists. This makes it all the more important to take the measure of Responsibility and Control, their most recent contribution to the historicist side of the discussion. In this paper I examine some novel features of their most recent version of responsiblity-historicism, especially their new notions of "moderate reasons-responsiveness" and "ownership-of-agency." Fischer and (...) Ravizza intend these new elements to solve two problems untouched by earlier versions of their theory: the "problem of strange preference patterns" and the "reasons-responsiveness problem of induction." I argue that they cannot solve these problems within the theoretical strictures they place upon themselves, namely a minimalist meta-ethics of value and practical reason, and attention only to certain formal features of preference-acquisition. I conclude that historicist compatibilists cannot hope to meet the challenge of structuralist compatibilism, from the one side, and of incompatibilism, from the other, unless they take on the full task of accounting for the difference between the child's acquisition of autonomous substantive preferences and values and her acquisition of heteronomous ones.

It has been claimed that justification, conceived traditionally in an internalist fashion, is not an epistemologically important property. I argue for the importance of a conception of justification that is completely dependent on the subject’s experience, using an analogy to advice. The epistemological importance of a property depends on two desiderata: the extent to which it guarantees the epistemic goal of attaining truth and avoiding falsehood, and the extent to which it depends only on the information available to the believer. (...) The traditional intermalist notion of justification completely satisfies the second desideratum and largely satisfies the first. (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.

In this paper I discuss the relation between various properties that have been regarded as important for determining whether or not a belief constitutes a piece of knowledge: its stability, strength and sensitivity to truth, as well as the strength of the epistemic position in which the subject is with respect to this belief. Attempts to explicate the relevant concepts more formally with the help of systems of spheres of possible worlds (à la Lewis and Grove) must take care to (...) keep apart the very different roles that systems of spheres can play. Nozicks sensitivity account turns out to be closer to the stability analysis of knowledge (versions of which I identify in Plato, Descartes, Klein and Lehrer) than one might have suspected. (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. After giving a rough sketch of several major features of epistemic intuitions, this article reviews the history of the current philosophical debate about them and describes the major positions in that debate. 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)

I shall be mainly concerned with the question ‘What is personal propositional knowledge?’. This question is obviously quite narrowly focused, in three respects. In the first place, there is impersonal as well as personal knowledge. Second, a distinction is often drawn between propositional knowledge and practical knowledge. And third, as well as asking what knowledge is, it is also possible to ask whether and how knowledge of various kinds can be acquired: causal knowledge, a priori knowledge, moral knowledge, and so (...) on. I shall dwell briefly on each of these three points. First, there is the distinction between personal and impersonal knowledge – in other words, between the psychological concept of knowledge and the social one.1 We use the concept of knowledge to describe the cognitive condition of individuals; but we also use it to describe the progress of scientific and historical research. So for example we can speak or enquire about the state of knowledge in a particular field of biology or history. And if we do so, we are evidently not concerned with what anyone in particular knows about, say, the genetics of fruit flies or the career of Charlemagne, but rather with what the scientific or academic community knows. Needless to say, there is a close connection between personal and impersonal knowledge. But ‘It is known that p’ does not simply mean ‘Someone or other. (shrink)

There is some consensus that for S to know that p, it cannot be merely a matter of luck that S’s belief that p is true. This consideration has led Duncan Pritchard and others to propose a safety condition on knowledge. In this paper, we argue that the safety condition is not a proper formulation of the intuition that knowledge excludes luck. We suggest an alternative proposal in the same spirit as safety, and find it lacking as well.

This essay extends my side of a discussion begun earlier with Duncan Pritchard, the recent author of Epistemic Luck. Pritchard’s work contributes significantly to improving the “diagnostic appeal” of a neo-Moorean philosophical response to radical scepticism. While agreeing with Pritchard in many respects, the paper questions the need for his concession to the sceptic that the neo-Moorean is capable at best of recovering “‘brute’ externalist knowledge”. The paper discusses and directly responds to a dilemma that Pritchard poses for virtue epistemologies (...) (VE). It also takes issue with Pritchard’s “merely safety-based” alternative. Ultimately, however, the criticisms made here of Pritchard’s dilemma and its underlying contrast of “anti-luck” and “virtue” epistemologies are intended to help realize his own aspirations for a better diagnosis of radical scepticism to inform a still better neo-Moorean response.

Harry Frankfurt has famously criticized the principle of alternate possibilities—the principle that an agent is morally responsible for performing some action only if able to have done otherwise than to perform it—on the grounds that it is possible for an agent to be morally responsible for performing an action that is inevitable for the agent when the reasons for which the agent lacks alternate possibilities are not the reasons for which the agent has acted. I argue that an incompatibilist about (...) determinism and moral responsibility can safely ignore so-called “Frakfurt-style cases ” and continue to argue for incompatibilism on the grounds that determinism rules out the ability to do otherwise. My argument relies on a simple—indeed, simplistic—weakening of the principle of alternate possibilities that is explicitly designed to be immune to Frankfurt -style criticism. This alternative to the principle of alternate possibilities is so simplistic that it will no doubt strike many readers as philosophically fallow. I argue that it is not. I argue that the addition of one highly plausible premise allows for the modified principle to be employed in an argument for incompatibilism that begins with the observation that determinism rules out the ability to do otherwise. On the merits of this argument I conclude that deterministic moral responsibility is impossible and that Frankfurt ’s criticism of the principle of alternate possibilities—even if successful to that end—may be safely ignored.

What''s computation? The received answer is that computation is a computer at work, and a computer at work is that which can be modelled as a Turing machine at work. Unfortunately, as John Searle has recently argued, and as others have agreed, the received answer appears to imply that AI and Cog Sci are a royal waste of time. The argument here is alarmingly simple: AI and Cog Sci (of the Strong sort, anyway) are committed to the view that cognition (...) is computation (or brains are computers); butall processes are computations (orall physical things are computers); so AI and Cog Sci are positively silly.I refute this argument herein, in part by defining the locutions x is a computer and c is a computation in a way that blocks Searle''s argument but exploits the hard-to-deny link between What''s Computation? and the theory of computation. However, I also provide, at the end of this essay, an argument which, it seems to me, implies not that AI and Cog Sci are silly, but that they''re based on a form of computation that is well beneath human persons.

This article provides a critical overview of competing theories of conceptual structure (definitional structure, probabilistic structure, theory structure), including the view that concepts have no structure (atomism). We argue that the explanatory demands that these different theories answer to are best accommodated by an organization in which concepts are taken to have atomic cores that are linked to differing types of conceptual structure.

A theory of information is developed in which the informational content of a signal (structure, event) can be specified. This content is expressed by a sentence describing the condition at a source on which the properties of a signal depend in some lawful way. Information, as so defined, though perfectly objective, has the kind of semantic property (intentionality) that seems to be needed for an analysis of cognition. Perceptual knowledge is an information-dependent internal state with a content corresponding to the (...) information producing it. This picture of knowledge captures most of what makes knowledge an important cpistcmological notion. It also avoids many of the problems infecting traditional justificational accounts of knowledge (knowledge as [justified, true belief those (unlike knowledge) having a content that can be either true or false (e.g., belief) – are described in terms of the way internal (presumably neural) structures acquire during learning a certain information-carrying role. The content of these structures (whether true or false) is identified with the kind of information they were developed to carry. (shrink)

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

It is commonly agreed that so-called echo chambers and epistemic bubbles, associated with social media, are detrimental to liberal democracies. Drawing on John Rawls’s political liberalism, we offer a novel explanation of why social media platforms amplifying echo chambers and epistemic bubbles are likely contributing to the violation of the democratic norms connected to the ideal of public reason. These norms are clarified with reference to the method of (full) reflective equilibrium, which we argue should be cultivated as a civic (...) virtue in the context of political justification. The paper demonstrates how epistemic bubbles and echo chambers are likely to be detrimental to the disposition to follow the method of reflective equilibrium in the political context. Based on this diagnosis the paper highlights the need for interventions that help cultivate reflective equilibrium as a civic virtue and the need for corresponding interdisciplinary research.

Situational aspects of action are discussed. The presented approach emphasizes the role of situational contexts in which actions are performed. These contexts influence the course of an action; they are determined not only by the current state of the system but also shaped by other factors as time, the previously undertaken actions and their succession, the agents of actions and so on. The distinction between states and situations is explored from the perspective of action systems. The notion of a situational (...) action system is introduced and its theory is expounded. Numerous examples illustrate the reach of the theory. (shrink)

According to a prevailing view, conceptual engineering introduces a revolutionary philosophical methodology, challenging traditional conceptual analysis. However, in our paper, we argue that closer scrutiny reveals not only the falsity but also the inherent ambiguity of this narrative. We explore four interpretations of the "Anti-Novelty Claim", the claim that conceptual engineering is not a new way of doing philosophy. Discussing the Anti-Novelty Claim from the perspective of a text’s producer, the text’s consumers, and the exegetical potential of the text, we (...) examine each perspective’s metaphilosophical implications and demonstrate that taking each perspective requires different methods. Adopting these different methods, we argue that the different interpretations of the Anti-Novelty Claim range from nearly trivially true to unlikely but untested. Importantly, we emphasize that each interpretation offers unique philosophical insights, yet addressing them requires diverse types of evidence, preventing a singular, straightforward answer to whether conceptual engineering is new.

I first present a brief interpretation of Sosa’s virtue epistemology by showing how it is arguably better than Goldman’s process reliabilism, why Sosa distinguishes between animal knowledge and reflective knowledge, and how Sosa’s recent account of knowing full well can deal with pragmatic encroachment. Then, I raise two worries about Sosa’s account: (a) Sosa’s claim that one might have animal knowledge without knowing reflectively or knowing full well implies that one’s true belief might manifest both competence and luck, which seems (...) to pose a challenge to Sosa’s solution to the Gettier problem; (b) intellectual virtue or competence does not seem to be a necessary condition for knowledge: there are cases where one knows without possessing the relevant intellectual virtue or competence. Finally, I suggest a responsibilist account of knowledge and show how it can not only handle the cases that pose a problem for Sosa’s account but also explain our intuitions about different grades of knowledge.

The current literature on norms of inquiry features two families of norms: norms that focus on an inquirer’s ignorance and norms that focus on the question’s soundness. I argue that, given a factive conception of ignorance, it’s possible to derive a soundness-style norm from a version of the ignorance norm. A crucial lemma in the argument is that just as one can only be ignorant of a proposition if the proposition is true, so one can only be ignorant with respect (...) to a question if the question is sound.

Questions surrounding deep disagreement have gained significant attention in recent years. One of the central debates is metaphysical, focusing on the features that make a disagreement deep. Proposals for what makes disagreements deep include theories about hinge propositions and first epistemic principles. In this paper, I criticize this metaphysical discussion by arguing that it is methodologically flawed. Deep disagreement is a technical or semi-technical term, but the metaphysical discussion mistakenly treats it as a common-sense concept to be analyzed and captured (...) by our pre-theoretical intuitions. Since the literature on deep disagreement is subject to this fundamental confusion and deep disagreement is not a helpful umbrella term either, I propose eliminating the notion of deep disagreement from the philosophical discourse. Instead of analyzing the nature of deep disagreement, we should develop theories about different forms of disagreement, including disagreement about hinge propositions and disagreement about epistemic principles, and, in particular, a theory of rationally irresolvable disagreement.

It might be that intuitions are central to philosophy, and it might be that this is true because when philosophers give case‐based arguments for philosophical claims (in published philosophy), the case verdict is typically (a) an intuited proposition and (b) either left undefended or defended on the grounds that it is an intuited proposition. This paper remains neutral on these global issues, however, and instead focuses on whether there is a nontrivial (or many‐membered) class of case‐based arguments in philosophy in (...) which the case verdict is defended by appeal to background beliefs and not on the grounds that it is an intuited proposition. The paper argues that the answer is affirmative by examining seven such arguments that are referred to as “paradigm cases” of case‐based arguments in which the verdict is justified via an appeal to intuition.

A recent focus on philosophical methodology has reinvigorated ordinary language philosophy with the contention that philosophical inquiry is better served by attending to the ordinary use of language. Taking cues from findings in the social sciences that deploy methods utilizing language, various ordinary language philosophers embrace a guiding mandate: that ordinary language usage is more reflective of our linguistic and conceptual competencies than standard philosophical methods. We analyze two hypotheses that are implicit in the research from which ordinary language approaches (...) take their cues. This pair of optimistic assumptions (a) bind word meanings to properties of their corresponding concepts and (b) regard language as a direct reflection of our underlying cognitive processes and competencies. Polysemy and pragmatics complicate each assumption. Because the ordinary language philosopher’s methodological mandate compels us to consider how individuals process the utterances they encounter in deciphering the communicative intentions of speakers, failing to attend to the import of polysemy and pragmatics in philosophical and empirical methods has the potential to frustrate the aims of their insightful mandate. The significance of those two complications is worked out with the case study of knowledge. (shrink)

In mathematics, the deductive method reigns. Without proof, a claim remains unsolved, a mere conjecture, not something that can be simply assumed; when a proof is found, the problem is solved, it turns into a “result,” something that can be relied on. So mathematicians think. But is there more to mathematical justification than proof? -/- The answer is an emphatic yes, as I explain in this article. I argue that non-deductive justification is in fact pervasive in mathematics, and that it (...) is in good epistemic standing. (shrink)

The method of cases (MOC), as standardly construed, involves an evidential appeal to intuitions. Philosophers, however, often argue for their case verdicts, they offer reasons for accepting their truth. According to Max Deutsch and Herman Cappelen – whose ground-breaking case studies first drew attention to this underappreciated phenomenon – their reason-giving would constitute compelling evidence that, contrary to the received view, philosophers relying on MOC regard arguments, not intuitions, as their main justificatory source. This explanatory hypothesis has met with substantial (...) resistance among metaphilosophers. The main goal of this paper is to broaden the theoretical playing field by considering a yet unexplored alternative hypothesis. I argue that said phenomenon in fact admits of an alternative, intuition-friendly explanation in light of a fundamental distinction in justification theory which has been entirely overlooked by the current debate – i.e. the one between justifying a belief and being justified in holding it. This distinction, I suggest, allows one to naturally construe philosophers’ justifying activity as a dialectically motivated kind of proactive reasoning geared toward the goal of maximizing consensus over their verdicts. Once thus construed, it remains compatible with philosophers thinking of intuitions as the main source of their justification. (shrink)

Paying attention to the inner workings of mathematicians has led to a proliferation of new themes in the philosophy of mathematics. Several of these have to do with epistemology. Philosophers of mathematical practice, however, have not (yet) systematically engaged with general (analytic) epistemology. To be sure, there are some exceptions, but they are few and far between. In this chapter, I offer an explanation of why this might be the case and show how the situation could be remedied. I contend (...) that it is only by conceiving the knowing subject(s) as embodied, fallible, and embedded in a specific context (along the lines of what has been done within social and feminist epistemology) that we can pursue an epistemology of mathematics sensitive to actual mathematical practice. I further suggest that this reconception of the knowing subject(s) does not force us to abandon the traditional framework of epistemology in which knowledge requires justified true belief. It does, however, lead to a fallible conception of mathematical justification that, among other things, makes Gettier cases possible. This shows that topics considered to be far removed from the interests of philosophers of mathematical practice might reveal to be relevant to them. (shrink)

I advance a novel argument for an infallibilist theory of knowledge, according to which we know all and only those propositions that are certain for us. I argue that this theory lets us reconcile major extant theories of knowledge, in the following sense: for any of these theories, if we require that its central condition (evidential support, reliability, safety, etc.) obtains to a maximal degree, we get a theory of knowledge extensionally equivalent to infallibilism. As such, the infallibilist can affirm (...) that, when their conditions are suitably interpreted, most post-Gettier theories of knowledge offer necessary and sufficient conditions for knowledge. The infallibilist can thus reconcile major theories of knowledge, and is in a better position to explain the intuitive appeal of these theories than the fallibilist who only accepts one of them, and rejects the rest.

According to predictive processing, an increasingly influential paradigm in cognitive science, the function of the brain is to minimize the prediction error of its sensory input. Conceptual engineering is the practice of assessing and changing concepts or word meanings. We contribute to both strands of research by proposing the first cognitive account of conceptual engineering, using the predictive processing framework. Our model reveals a new kind of implementation problem as prediction errors are only minimized if enough agents embrace conceptual changes. (...) This problem can be overcome by emphasizing the importance of social norms and conceptual pluralism. (shrink)

This chapter discusses epistemic objections to non-naturalist moral realism. The goal of the chapter is to determine which objections are pressing and which objections can safely be dismissed. The chapter examines five families of objections: (i) one involving necessary conditions on knowledge, (ii) one involving the idea that the causal history of our moral beliefs reflects the significant impact of irrelevant influences, (iii) one relying on the idea that moral truths do not play a role in explaining our moral beliefs, (...) (iv) one involving the claim that if moral realism is true then our moral beliefs are unlikely to be reliable, and (v) one involving the claim that moral realism is incompatible with there being a plausible explanation of our reliability about morality. The overall conclusion of the chapter is that the final objection is by far the most pressing. (shrink)

In this paper, I develop an account of epistemic justice as a character-based intellectual virtue that a truth-desiring agent would want to possess. The agent who possesses this virtue is just towards other knowers in matters pertaining to epistemic goods and this involves a regard for agents as knowers. Notably, the virtue of epistemic justice has a unique position among virtues: epistemic justice is presupposed by every other intellectual virtue, while remaining a standalone virtue itself. Correspondingly, I also offer an (...) account of the vice of epistemic injustice as an epistemically dis-valuable trait of character. The agent who possesses this trait is unjust towards other knowers in matters pertaining to epistemic goods and this involves a disregard for agents as knowers. Most importantly, I highlight that the vice of epistemic injustice is entailed by every other epistemic vice, though it remains a distinct vice. (shrink)

Beliefs should conform to some norms. Epistemic instrumentalism holds that your beliefs should conform to these epistemic norms just because conforming is useful. But there seems to be cases where conforming to the epistemic norms isn’t useful at all, as in so-called “too-few-reasons” cases. In response to these cases, universal epistemic instrumentalists argue that despite first appearances, it is always useful to conform to the epistemic norms. I argue that all current versions of this universalist response are objectionable. I conclude (...) with a conjecture about why no version of universalism will succeed. (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. On what grounds, according to DiAngelo, can people know what they claim to know? And on what grounds does DiAngelo know what she claims to know?

Reasons rationalize beliefs. Reasons, when all goes well, turn true beliefs into knowledge. I am interested in the relationship between these aspects of reasons. Without a proper understanding of their relationship, the theory of knowledge will be less illuminating than it ought to be. I hope to show that previous accounts have failed to account for this relationship. This has resulted in a tendency to focus on justification rather than knowledge. It has also resulted in many becoming skeptical about the (...) prospects for an analysis of knowledge. The skepticism is misplaced and the tendency can be fixed without sacrificing any insights. The solution is to see how good reasons (in a sense to be articulated) are apparent (in a sense to be articulated) to the knowing subject. Once this claim is unpacked, we see that it is an illuminating analysis of knowledge in terms of distinct but intimately related aspects of epistemic assessment. It helps us see the value of knowledge (over and above true belief) and it affords us a unified, “reasons-first” metaepistemology. The resulting picture is neither a familiar kind of internalism or externalism. (shrink)

This work investigates intuitions' nature, demonstrating how philosophers can best use them in epistemology. First, the author considers several paradigmatic thought experiments in epistemology that depict the appeal to intuition. He then argues that the nature of thought experiment-generated intuitions is not best explained by an a priori Platonism. Second, the book instead develops and argues for a thin conception of epistemic intuitions. The account maintains that intuition is neither a priori nor a posteriori but multi-dimensional. It is an intentional (...) but non-propositional mental state that is also non-conceptual and non-phenomenal in nature. Moreover, this state is individuated by its progenitor, namely, the relevant thought experiment. Third, the author provides an argument for the evidential status of intuitions based on the correct account of the nature of epistemic intuition. The suggestion is the fitting-ness approach: intuition alone has no epistemic status. Rather, intuition has evidentiary value as long as it fits well with other pieces into a whole, namely, the pertinent thought experiment. Finally, the book addresses the key challenges raised by supporters of anti-centrality, according to which philosophers do not regard intuition as central evidence in philosophy. To that end, the author responds to them, showing that they fail to affect the account of intuition developed in this book. This text appeals to students and researchers working in epistemology.

Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For naturalists of all (...) stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

Dieses Grundlagenwerk soll die Fundamente der Erkenntnistheorie und philosophischen Ethik vollständig neu herleiten, sowie den aktuellen Forschungsstand auf einen wahren Kern herunterbrechen und kritisch zusammenfassen. Im Zentrum steht dabei die Frage, inwiefern Erkenntnis der Wirklichkeit möglich ist, sowie die Suche nach elementaren, rationalen Rechtfertigungen, auf denen jegliche Erkenntnis aufbaut. Über fünfzehn Jahre hinweg habe ich dazu das Rechtfertigungsproblem ergründet, sowie herkömmliche Theorien und Argumentationen umfassend analysiert. Mit diesem Grundlagenwerk will ich einen voraussetzungsfreien, vollständig hergeleiteten Erkenntnisstand schaffen und ihn auf ein (...) sicheres Fundament stellen. Mein Ziel ist es, eine moderne Erkenntnistheorie aufzustellen, die eine vollständige Rechtfertigung auf allen Ebenen liefern kann. ––––––––––––––– Programm (mit fachlichen Begrifflichkeiten): Der erkenntnistheoretische Teil untersucht die ontologischen und epistemischen Fragen des Realismus von Wirklichkeit und Bewusstsein. Die physikalische Wirklichkeit scheint sich fundamental und damit auch ontologisch von (phänomenalen) Bewusstsein zu unterscheiden, und dieses zu determinieren (psychophysische Supervenienz; Epiphänomenalismus). Es wird untersucht, ob sich die Realismus-Hypothese der Wirklichkeit aus selbstevidenten Basisüberzeugungen einer Fundierungstheorie (unseren momentanen Bewusstseinsinhalten) und fundamentalen Schlussmethoden rational begründen lässt (instrumentalistische Rechtfertigung). Die Existenz und Erkennbarkeit der Wirklichkeit könnte dabei logisch aus einem intuitiven, direkten Realismus übertragen werden (realistische Rechtfertigung). Unsere fundamentalen Schlussmethoden, um von Gegebenen auf Unbekanntes zu schließen, lassen sich als bestimmte Arten von Induktion und Abduktion identifizieren, deren herkömmliche Begründungsversuche untersucht werden. So werden unsere induktiven, abduktiven, rationalen und logischen Grundlagen für Erkenntnisse, Annahmen und Theorien untersucht. Da Überzeugungen über Basisüberzeugungen hinaus immer unsicher sind, muss ihre Rechtfertigung nach dem Regressproblem in fundamentalen Schlüssen bzw. Rechtfertigungen enden, die schlicht gegeben sind, und nicht weiter gerechtfertigt werden können. Es zeigt sich, dass diese Schlüsse (bzw. Rechtfertigungen von nicht-Gegebenen) möglicherweise unserer fundamentalen intuitiven Rationalität bzw. Logik entspringen (Intuitionismus) – bzw. nur dadurch gerechtfertigt werden können, dass sie dieser entsprechen. (Dies entspricht einer intuitionistisch bzw. internalistisch-naturalistisch erweiterten Fundierungstheorie.) Diese rein idealistische Argumentation, wird durch die Annahme, dass wir in einer physikalischen Wirklichkeit leben, „bestätigt“, da unser gesamtes Denken letztlich durch die Strukturen unseres Gehirns determiniert ist (Evolutionäre Erkenntnistheorie). Abduktion und Induktion scheinen der rational alternativlosen, fundamentalen kognitiven Disposition zu entspringen, Gleichheiten bzw. sich wiederholende Unterschiede zusammenzufassen, und logische Verknüpfungen zu erkennen. Dies entspricht einer Reduktion gegebener Evidenz auf einen Informationsgehalt. Die realistische Rechtfertigung von Abduktion und auf ihr basierender Induktion scheint ebenfalls aus unserer fundamentalen Rationalität zu entspringen, und in ihrer Überzeugungsstärke an die Stärke der reduktiven Abduktivität gekoppelt zu sein. So nehmen wir reale, notwendige, induktiv fortgesetzte Gesetzmäßigkeiten an. Jeder externalistische Erkenntnisanspruch scheint nur internalistisch gerechtfertigt werden zu können. Auch eine Rechtfertigung mittels Kohärenz (Kohärentismus) scheint auf Abduktion zu gründen. Die alltäglichen Verwendungen der Begriffe Wahrheit und Wissen verweisen aufgrund ihrer verschiedenen, aufeinander aufbauenden, fehlbaren Rechtfertigungsarten bzw. -stärken auf einen Kontextualismus des Begriffs der Rechtfertigung. Wahrheit und Wissen scheinen also möglicherweise für ein Subjekt nur unvollständig gerechtfertigt sein zu müssen, bis die Unvollständigkeit bzw. Fehlbarkeit ihrer Rechtfertigung begründet aufgezeigt wird (Epistemic Conservatism). Der Teil zur philosophischen Ethik untersucht das Konzept der Normativität und ethische Begriffe wie das Sollen, der Wertung und das Gute. Ethische/moralische Inhalte werden hinsichtlich ihrer Ontologie, Bedeutung, Wahrheit und Objektivität untersucht. Dazu zählt eine Analyse ethischer Theorien und Konzepte, wie Sensualismus, Subjektivismus, Relativismus, Realismus, Teleologie, Deontologie, Utilitarismus und moralischer Status. Dabei wird unter anderem geklärt, ob normative Fragen letztlich in kausalen Fakten gründen müssen (Naturalismus, Nonkognitivismus), also insofern rein beschreibend beantwortet werden können. Zuletzt wird eine präzise Definition des Begriffs der Gerechtigkeit aufgestellt. (shrink)

The paper analyzes the problem of interpretations of the Gettier problem. The author draws a distinction between counterexamples presented in Edmund Gettier’s article and Gettier-style cases, between the Gettier problem and general epistemological problem supposedly occurring in all or many Gettier-style cases. It is argued that in Gettier’s article there is a gap associated with an insufficiently defined concept of justification, which does not allow talking about Gettier problem without any explicit or implicit interpretation of his views on justification. Along (...) with this, it is indicated that the same concept of justification has strict features (deductive closure principle, non-factive justification and internalism), which do not allow arbitrary interpretations of the Gettier problem, and therefore we can say that some interpretations are closer to the text of a well-known article.

Deviant causal chain problems arise in many settings. The most famous instance of the problem is the Gettier problem, but the problem also arises in the philosophy of action and perception. Usually, attempts to tackle these problems try to solve them individually. This paper takes a different approach: I propose a general solution to the problem. I begin by providing a solution to the deviant causal chain problem for skillful performance, and I argue that the solution can be extended to (...) solve the Gettier problem and the deviant causal chain problems for perception and intentional action. As I develop my solution to these problems, I also compare it with other solutions to bring out the advantages of my approach. I then explain why the solution generalizes: my solution provides us with an analysis of disposition manifestation, which is the key to ruling out deviance. I conclude by considering objections and giving my replies. (shrink)

Metaethical debunking arguments often conclude that no moral belief is epistemically justified. Early versions of such arguments largely relied on metaphors and analogies and left the epistemology of debunking underspecified. Debunkers have since come to take on substantial and broad-ranging epistemological commitments. The plausibility of metaethical debunking has thereby become entangled in thorny epistemological issues. In this thesis, I provide a critical yet sympathetic evaluation of the prospects and challenges facing such arguments in light of this development. In doing so, (...) I address the following central question: how could genealogical information undermine the epistemic justification of moral beliefs? In Part I, I begin answering the central question by extracting explicit and implicit epistemic principles from three popular debunking arguments. These arguments, due to Gilbert Harman, Richard Joyce, and Sharon Street, generate principles concerning ontological parsimony, explanatory dispensability, epistemic insensitivity, lack of epistemic safety, unexplained reliability, epistemic coincidences, and explanatory constraints on rational belief. Having set out the principles tasked with explaining how genealogical information undermines, Part II of the thesis seeks to evaluate whether debunking arguments built on them succeed. To this end, I consider two types of challenges faced by such arguments. First, there are strategies that attempt to block global moral debunking arguments. I argue that one popular such strategy, the so-called ‘third-factor strategy’, has been misunderstood. When understood correctly, it is of no help in answering debunking arguments. I then flesh out an alternative and more promising strategy for blocking such arguments. I then turn to internal challenges facing debunkers, particularly those who rely on ‘explanationist’ principles. I argue that explanationist debunking arguments, as well as most others, fall prey to one or more of four internal challenges: the implausibility of first-order epistemic principles, the threat of overgeneralization, the threat of self-defeat, and the need for costly metaepistemic commitments. I conclude that current debunking arguments fail to establish that no moral belief is justified. By analyzing why existing arguments fail, I develop two conditions of adequacy that debunkers must satisfy in order to navigate the internal challenges successfully. I end by suggesting future directions that debunkers should pursue to rehabilitate the prospects for global moral debunking arguments. (shrink)

Overconfidence is typically damaging to one’s reputation as a trustworthy source of information. Previous research shows that the reputational cost associated with conveying a piece of false information is higher for confident than unconfident speakers. When judging speaker trustworthiness, individuals do not exclusively rely on past accuracy but consider the extent to which speakers expressed a degree of confidence that matched the accuracy of their claims (their “confidence-accuracy calibration”). The present study experimentally examines the interplay between confidence, accuracy and a (...) third factor, namely evidence, in the assessment of speaker trustworthiness. Experiment 1 probes the hypothesis that overconfidence does not backfire when a confident but inaccurate claim is justified: the trustworthiness of a confident speaker who turns out to be wrong is restored if the confidence expressed is based on strong evidence (good confidence-evidence calibration). Experiment 2 investigates the hypothesis that confidence can backfire if a confident and accurate claim is not justified: the trustworthiness of a confident speaker who turns out to be right is damaged if the confidence expressed is based on weak evidence (bad confidence-evidence calibration). Our results support both hypotheses and thus suggest that “confidence-evidence calibration” plays a crucial role in the assessment of speaker trustworthiness. (shrink)

Safety purports to explain why cases of accidentally true belief are not knowledge, addressing Gettier cases and cases of belief based on statistical evidence. However, problems arise for using safety as a condition on knowledge: safety is not necessary for knowledge and cannot always explain the Gettier cases and cases of statistical evidence it is meant to address. In this paper, I argue for a new modal condition designed to capture the non-accidental relationship between facts and evidence required for knowledge: (...) causal safety. I argue that possible errors in belief can be captured by accounting for deviations in causal relationships and that there is a natural way to characterize which causal errors are relevant in an epistemic situation. Using this, I develop a causal analogue to safety, where one’s belief in p is causally safe if it is true in all causally relevant worlds where one believes p. Causal safety, I argue, can better explain the cases safety is meant to address and can avoid the arguments raised against the necessity of safety. (shrink)

Epistemologists have long believed that epistemic luck undermines propositional knowledge. Action theorists have long believed that agentive luck undermines intentional action. But is there a relationship between agentive luck and epistemic luck? While agentive luck and epistemic luck have been widely thought to be independent phenomena, we argue that agentive luck has an epistemic dimension. We present several thought experiments where epistemic luck seems to undermine both knowledge-how and intentional action and we report experimental results that corroborate these judgments. These (...) findings have implications for the role of knowledge in a theory of intentional action and for debates about the nature of knowledge-how and the significance of knowledge representation in folk psychology.

Forming a belief on the basis of accepting another’s testimony often involves a kind of reliance on the (say-so of the) testifier. I argue that this reliance has epistemically relevant features that cannot be represented in most mainstream theories in the epistemology of testimony. The targeted views are those that embrace individualism about testimonial justification.

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)

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)

Epistemologists have posed the following puzzle, known as the proof paradox: Why is it intuitively problematic for juries to convict on the basis of statistical evidence and yet intuitively unproblematic for juries to convict on the basis of far less reliable, non-statistical evidence? To answer this question, theorists have explained the exclusion of statistical evidence by arguing that legal proof requires certain epistemic features. In this paper, I make two contributions to the debate. First, I establish the Criminal Verdict Asymmetry, (...) a previously-unarticulated asymmetry between the epistemic norms of guilty and not guilty verdicts. I argue that the prosecution and defense’s different epistemic burdens influence whether statistical evidence can generate the type of verdict each side pursues. Second, I point out a mistake in how theorists have understood the role of statistical evidence in criminal trials. Though epistemologists have primarily focused on whether statistical evidence can generate specific epistemic features required for convictions, I consider whether statistical evidence can demonstrate a lack of such features. I find that there are epistemic advantages to allowing the defense to introduce statistical evidence which can reveal the prosecution’s failure to prove the defendant’s guilt. (shrink)

This paper aims to outline, and argue for, an approach to episodic memory broadly in the spirit of knowledge-first epistemology. I discuss a group of influential views of epsiodic memory that I characterize as ‘two-factor accounts’, which have both proved popular historically and have also seen a resurgence in recent work on the philosophy of memory. What is common to them is that they try to give an account of the nature of episodic memory in which the concept of knowledge (...) plays no explanatory role. I highlight some parallels between these two-factor accounts and attempts to give a reductive definition of knowledge itself. I then discuss some problems two-factor accounts of episodic memory face in explaining the distinctive sense in which episodic recollection involves remembering personally experienced past events, before sketching an alternative approach to episodic memory, which takes as basic the idea that episodic memory involves the retention of knowledge. I argue that we can give an exhaustive constitutive account of what episodic memory is, and how it differs from other types of mental states, by considering what particular type of knowledge is retained in episodic memory, and what exactly having that knowledge consists in.
