Existing discussions of legal proof address a host of apparently disparate questions: What does it take to prove a fact beyond a reasonable doubt? Why is the reasonable doubt standard notoriously elusive, sometimes considered by courts to be impossible to define? Can the standard of proof by a preponderance of the evidence be defined in terms of probability thresholds? Why is statistical evidence often insufficient to meet the burden of proof? -/- This paper defends an account of proof that addresses (...) each of these questions. Where existing theories take a piecemeal approach to these puzzles, my theory develops an insight that unifies them—namely, the thesis that legal proof requires knowledge. Although this thesis may seem radical at first, I answer several common objections to it, and I argue that it does better than several competing accounts when it comes to making sense of our intuitions about what legal proof requires.

In this paper we will try to show the differences between Quine’s and Gibson’s interpretation of the naturalized epistemology project. Namely, although Gibson points out that the genetic approach advocated by Quine is the best strategy there is to investigate the relations between evidence and theory, and that externalizing of empiricism that it requires is one of Quine’s major philosophical contributions, we argue that the assumptions on which Gibson’s project is based, apart from the fact that they are in conflict (...) with some strongly held intuitions, would have to be essentially different from Quine’s. In other words, contrary to Quine’s position within which we have the possibility of staying on more moderate, and in our opinion, more plausible behavioristic line of approach, we will try to show that one of the consequences of Gibson’s interpretation is that this possibility is ruled out in Gibson’s case. On the other hand, this should enable us to draw some more radical conclusions about the nature of Quine’s epistemological project. (shrink)

While C. I. Lewis was traditionally interpreted as an epistemological foundationalist throughout his major works, virtually every recent treatment of Lewis's epistemology dissents. But the traditional interpretation is correct: Lewis believed that apprehensions of "the given" are certain independently of support from, and constitute the ultimate warrant for, objective empirical beliefs. This interpretation proves surprisingly capable of accommodating apparently contrary textual evidence. The non-foundationalist reading, by contrast, simply cannot explain Lewis's explicit opposition to coherentism and his insistence that only apprehensions (...) of the given enable us to answer the regress problem -- and so vindicate the possibility of empirical justification.

In this thesis, I elaborate and defend Donald Davidson's account of knowing one's own mental states that exhibit first-person authority. To that end, I place Davidson's account among others in the philosophical landscape concerning self-knowledge. Next, I examine his response to philosophical challenges that arise from mental content externalism and self-deception. Finally, I draw some insights froms Davidson's account to the broader aims of epsitemology.

This chapter reviews some faults of the theoretical literature and findings from the experimental literature on “Gettier” cases. Some “Gettier” cases are so poorly constructed that they are unsuitable for serious study. Some longstanding assumptions about how people tend to judge “Gettier” cases are false. Some “Gettier” cases are judged similarly to paradigmatic ignorance, whereas others are judged similarly to paradigmatic knowledge, rendering it a theoretically useless category. Experimental procedures can affect how people judge “Gettier” cases. Some important central tendencies (...) in judging “Gettier” cases appear to be robust against demographic variation in biological sex, age, language, and culture, although there could be some interesting differences related to culture and personality traits. Some remaining questions regarding Gettier’s cases, “Gettier” cases, and “the Gettier problem” concern the psychology and sociology of contemporary anglophone theoretical epistemology. Some remaining questions regarding the empirical study of knowledge judgments concern mechanisms underlying observed behavioral patterns. (shrink)

The book provides a historical and systematic exposition of the semantic theory of truth formulated by Alfred Tarski in the 1930s. This theory became famous very soon and inspired logicians and philosophers. It has two different, but interconnected aspects: formal-logical and philosophical. The book deals with both, but it is intended mostly as a philosophical monograph. It explains Tarski’s motivation and presents discussions about his ideas as well as points out various applications of the semantic theory of truth to philosophical (...) problems. (shrink)

The author uses a series of potential counterexamples to argue against attempts by Bergmann and Plantinga to articulate a distinction between malignant and benign epistemic circularity and, more radically, to argue that epistemic circularity per se is no fallacy, and the concept of epistemic circularity plays no role in the explanation of why some instances of epistemic circularity are irrational. The author contrasts an inferential framework, in which circularity is a problem, with an equilibrium framework, in which the concept of (...) circularity plays no useful role and argues that defeasible reasoning can only be understood in an equilibrium, not an inferential, framework. The author uses an example of reasoning about the reliability of one’s own memory to explain how seemingly malignant epistemic circularity can be rational in an equilibrium framework. The author discusses the relevance of this conclusion to two contemporary issues: the cogency of Plantinga’s Evolutionary Argument against Naturalism and the evolutionary naturalists’ challenges to non-naturalist moral realism—and, indeed, to all forms of non-naturalist normative realism.

We cannot rethink the ethical and political dimensions of memory—especially its role in constituting persons and identities—without rethinking the nature of memory itself. I first describe a traditional epistemological view of memory, according to which memory is a faculty for preserving knowledge of the past, and then juxtapose a relational theory of memory developed by Sue Campbell. The relational theory is represented in terms of a distinction between actions and achievements; this distinction enables us to both clarify and defend the (...) shift from an epistemological to a political conception of memory. On the resulting view, accuracy, not truth, is the appropriate norm for evaluating memory, and remembering is no longer conceived as an interior process. In the penultimate section I confront an objection to a relational theory of memory—and to relational theories of cognition generally—and suggest a strategy of response. (shrink)

According to infinitism, all justification comes from an infinite series of reasons. Peter Klein defends infinitism as the correct solution to the regress problem by rejecting two alternative solutions: foundationalism and coherentism. I focus on Klein's argument against foundationalism, which relies on the premise that there is no justification without meta-justification. This premise is incompatible with dogmatic foundationalism as defended by Michael Huemer and Time Pryor. It does not, however, conflict with non-dogmatic foundationalism. Whereas dogmatic foundationalism rejects the need for (...) any form of meta-justification, non-dogmatic foundationalism merely rejects Laurence BonJour's claim that meta-justification must come from beliefs. Unlike its dogmatic counterpart, non-dogmatic foundationalism can allow for basic beliefs to receive meta-justification from non-doxastic sources such as experiences and memories. Construed thus, non-dogmatic foundationalism is compatible with Klein's principle that there is no justification without meta-justification. I conclude that Klein's rejection of foundationalism. fails. Nevertheless, I agree with Klein that when in response to a skeptical challenge we engage in the activity of defending our beliefs, the number of reasons we can give is at least in principle infinite. I argue that this type of infinity is benign because, when we continue to give reasons, we will eventually merely repeat previously stated reasons. Consequently, I reject Klein's claim that the more reasons we give the more we increase the justification of our beliefs. (shrink)

In “A well-founded solution to the generality problem,” Comesaña argues, inter alia, for three main claims. One is what I call the unavoidability claim: Any adequate epistemological theory needs to appeal, either implicitly or explicitly, to the notion of a belief’s being based on certain evidence. Another is what I call the legitimacy claim: It is perfectly legitimate to appeal to the basing relation in solving a problem for an epistemological theory. According to Comesaña, the legitimacy claim follows straightforwardly from (...) the unavoidability claim. The third one is what I call the basing solution claim: An appeal to the notion of basing relation is all we need to solve the generality problem for (process) reliabilism. In this paper, I will argue that the unavoidability claim and the basing solution claim are false and that the legitimacy claim might be true only in a qualified sense. (shrink)

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception, suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

Interest-relative invariantism is the view that practical interests encroach upon knowledge. In other words, the more that is at stake for S, the harder it is for her true belief to be an instance of knowledge. Russell and Doris argue that IRI theorists are committed to indifference being knowledge-making feature of IRI, where knowledge comes easier for subjects the less they care. In this paper, I explain why indifference cases are problematic and which assumptions about IRI generate them. I then (...) argue IRI theorists can immunize themselves from indifference problems by grounding practical interests in either Aristotelianism or a restricted form of Humeanism, both of which link practical interests to some conception of well-being. I then argue that besides solving indifference problems, these approaches present a reasonable conception of practical interests, while also saving IRI theorists from abandoning plausible theses about knowledge.

I argue that knowledge is a particular kind of concept known as a thick concept. Examples of thick concepts include courage, generosity, loyalty, brutality, and so forth. These concepts are commonly said to combine both evaluation and description, and one of the main goals of this dissertation is to provide a new account of how a thick concept combines these elements. It is argued that thick concepts are semantically evaluative, and that they combine evaluation and description in a way similar (...) to that of concepts like good qua dancer and bad qua violinist. In the final chapter, this basic idea is applied to the concept of knowledge. There, the concept of knowledge is analyzed in terms of good qua belief. The upshot is that two central epistemological problems—the Gettier Problem and the Value Problem—can be resolved. (shrink)

Anscombe thought that practical knowledge – a person’s knowledge of what she is intentionally doing – displays formal differences to ordinary empirical, or ‘speculative’, knowledge. I suggest these differences rest on the fact that practical knowledge involves intention analogously to how speculative knowledge involves belief. But this claim conflicts with the standard conception of knowledge, according to which knowledge is an inherently belief-involving phenomenon. Building on John Hyman’s account of knowledge as the ability to use a fact as a reason, (...) I develop an alternative, two-tier, epistemology which allows that knowledge might really come in a belief-involving and an intention-involving form. (shrink)

In this paper a new conception of foundation-oriented epistemology is developed. The major challenge for foundation-oriented justifications consists in the problem of stopping the justificational regress without taking recourse to dogmatic assumptions or circular reasoning. Two alternative accounts that attempt to circumvent this problem, coherentism and externalism, are critically discussed and rejected as unsatisfactory. It is argued that optimality arguments are a new type of foundation-oriented justification that can stop the justificational regress. This is demonstrated on the basis of a (...) novel result in the area of induction: the optimality of meta-induction. In the final section the method of optimality justification is generalized to deductive and abductive inferences. (shrink)

Scientific realists argue that a good track record of multi-agent, and multiple method, validation of empirical claims is itself evidence that those claims, at least partially and approximately, reflect ways nature actually is independent of the ways we conceptualize it. Constructivists contend that successes in validating empirical claims only suffice to establish that our ways of modelling the world, our “constructions,” are useful and adequate for beings like us. This essay presents a thought experiment in which beings like us intersubjectively (...) validate claims about properties of particular things in nature under conditions in which those beings have profoundly different personal phenomenological experiences of those properties. I submit that the thought experiment scenario parallels our actual situation, and argue that this shows that successes in intersubjectively validating empirical claims are indeed enough to claim victory for the realist. More specifically, I champion a variation of realism that marries Ronald Giere’s brand of ‘perspectival realism’ with Philip Kitcher’s ‘real realism,’ and posits that causal relations between ourselves and properties instantiated in nature ground our references to the relevant properties even though our conceptions of them are perspective relative.

An agent’s belief in a proposition, E0, is justified by an infinite regress of deferred justification just in case the belief that E0 is justified, and the justification for believing E0 proceeds from an infinite sequence of propositions, E0, E1, E2, etc., where, for all n ≥ 0, En+1 serves as the justification for En. In a number of recent articles, Atkinson and Peijnenburg claim to give examples where a belief is justified by an infinite regress of deferred justification. I (...) argue here that there is no reason to regard Atkinson and Peijnenburg’s examples as cases where a belief is so justified. My argument is supported by careful consideration of the grounds upon which relevant beliefs are held within Atkinson and Peijnenburg’s examples. (shrink)

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

The epistemological problem of the external world asks: (1) “How is knowledge of the external world possible given certain obstacles which make it look impossible?” This is a “how-possible?” question: it asks how something is possible given certain obstacles which make it look impossible (cf. Cassam 2007; Nozick 1981; Stroud 1984). Now consider the following question, which asks: (2) “How is a philosophically satisfying answer to (1) possible?” Skepticism is the thesis that knowledge of the external world is impossible. It (...) therefore represents a negative answer to the first question. Meta-epistemological skepticism is the thesis that a satisfying philosophical explanation of how our knowledge of the external world is possible is itself impossible. It therefore represents a negative answer to the second question. In this thesis, I explore the prospects of meta-epistemological skepticism. In particular, I structure the thesis around two master arguments from for meta-epistemological skepticism. The first argument is that skepticism represents a kind of paradox which requires dispensing with a plausible principle or belief, or even 'platitude', which means that there's no philosophically satisfying response to the paradox (see, e.g., Stroud 1984), and the second argument is “Stroud’s dilemma” (cf. Cassam 2009), that either we explain how external world knowledge is possible by reference to what external world knowledge we have, thereby failing to answer the philosophical question adequately, or else we don't, but then we succumb to first-order skepticism. I argue that the first argument fails to provide adequate support for meta-epistemological skepticism. However, the second argument, Stroud’s dilemma, is plausible and withstands serious objections (e.g., from Sosa 1994, Williams 1996, and Cassam 2009). In short, while the worry emerging out of the 'skeptical paradox' view fails to adequately support meta-epistemological skepticism, Stroud’s dilemma succeeds. Fortunately, it doesn't show that we lack external world knowledge; we rather just can't explain, philosophically, how it's possible. We may have first-order knowledge without understanding how it's possible. This thesis therefore represents a partial defense of meta-epistemological skepticism. Meta-epistemological skepticism is a live option in epistemology. (shrink)

Mainstream analytic epistemology regards knowledge as the property of individuals, rather ‎than groups. Drawing on insights from the reality of knowledge production and dissemination ‎in the sciences, I argue, from within the analytic framework, that this view is wrong. I defend ‎the thesis of ‘knowledge-level justification communalism’, which states that at least some ‎knowledge, typically knowledge obtained from expert testimony, is the property of a ‎community and possibly none of its individual members, in that only the community or some ‎members (...) of it collectively possesses knowledge-level justification for its individual members’ ‎beliefs. I address several objections that individuals, qua individuals, have or are able to ‎acquire knowledge-level justification for all the beliefs they obtain from expert testimony. I ‎argue that the problem I identify with individualism is invariant under any specific account of ‎justification, internalist or externalist. ‎. (shrink)

Looking out the window, I see that it's raining outside. Do I know that it’s raining outside? According to proponents of the Entailment Thesis, I do. If I see that p, I know that p. In general, the Entailment Thesis is the thesis that if S perceives that p, S knows that p. But recently, some philosophers (McDowell 2002, Turri 2010, Pritchard 2011, 2012) have argued that the Entailment Thesis is false. On their view, we can see p and not (...) know that p. In this paper, I argue that their arguments are unsuccessful. (shrink)

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

The question of authenticity centers in the lives of women of color to invite and restrict their representative roles. For this reason, Gayatri Chakravorty Spivak and Uma Narayan advocate responding with strategic essentialism. This paper argues against such a strategy and proposes an epistemic understanding of the question of authentic- ity. The question stems from a kernel of truth—the connection between experience and knowledge. But a coherence theory of knowledge better captures the sociality and the holism of experience and knowledge.

Current scientific research on consciousness aims to understand how consciousness arises from the workings of the brain and body, as well as the relations between conscious experience and cognitive processing. Clearly, to make progress in these areas, researchers cannot avoid a range of conceptual issues about the nature and structure of consciousness, such as the following: What is the relation between intentionality and consciousness? What is the relation between self-awareness and consciousness? What is the temporal structure of conscious experience? What (...) is it like to imagine or visualize something, and how is this type of experience different from perception? How is bodily experience related to self-consciousness? Such issues have been addressed in detail in the philosophical tradition of phenomenology, inaugurated by Edmund Husserl (1859-1938) and developed by numerous other philosophers throughout the 20th century. This chapter provides an introduction to this tradition and its way of approaching issues about consciousness. We first discuss some features of phenomenological methodology and then present some of the most important, influential, and enduring phenomenological proposals about various aspects of consciousness. These aspects include intentionality, self-awareness and the first-person perspective, time-consciousness, embodiment, and intersubjectivity. We also highlight a few ways of linking phenomenology and cognitive. (shrink)

in Robin Le Poidevin (ed.) Being: Developments in Contemporary Metaphysics. Cambridge: Cambridge University Press. Peter van Inwagen claims that there are no tables or chairs. He also claims that sentences such as ‘There are chairs here’, which seem to imply their existence, are often true. This combination of views opens van Inwagen to a charge of self-contradiction. I explain the charge, and van Inwagen’s response to it, which involves the claim that sentences like ‘There are tables’ shift their truth-conditions between (...) different contexts of utterance. I present an alternative response which involves the negation of that claim, and argue that it is preferable to van Inwagen’s. (shrink)

Whether empirical givenness has the reliability that foundationalists expect is a point about which some philosophers are highly skeptical. Sellars took the doctrine of givenness as a “myth,” denying the existence of immediate perceptual experience. The arguments in contemporary Western epistemology are concentrated on whether sensory experience has conceptual contents, and whether there is any logical relationship between perceptions and beliefs. In fact, once the elements of words and conceptions in empirical perception are affirmed, the logical relationship between perceptual experience (...) and empirical belief is also affirmed. This relationship takes place through perceptual experience acting as evidence for beliefs. The real problem lies in how one should distinguish between the different relationships with perception of singular beliefs and of universal beliefs, and in how singular beliefs can provide justification for universal beliefs.

Truthmaker theory promises to do some useful philosophical work: equipping us to argue against phenomenalism and Rylean behaviourism, for instance, and helping us decide what exists (Lewis 1999, 207; Armstrong 1997, 113-119). But it has proved hard to formulate a truthmaker theory that is both useful and believable. I want to suggest that a neglected approach to truthmakers – that of Ian McFetridge – can surmount some of the problems that make other theories of truthmaking unattractive. To begin with, I’ll (...) outline some of the most prominent accounts of truthmaking in the current literature. Then the second part of the paper will explain McFetridge’s theory and argue for its superiority over these accounts. (shrink)

The tripartite account of propositional, fallibilist knowledge that p as justified true belief can become adequate only if it can solve the Gettier Problem. However, the latter can be solved only if the problem of a successful coordination of the resources (at least truth and justification) necessary and sufficient to deliver propositional, fallibilist knowledge that p can be solved. In this paper, the coordination problem is proved to be insolvable by showing that it is equivalent to the ''''coordinated attack'''' problem, (...) which is demonstrably insolvable in epistemic logic. It follows that the tripartite account is not merely inadequate as it stands, as proved by Gettier-type counterexamples, but demonstrably irreparable in principle, so that efforts to improve it can never succeed.

This paper challenges the standard conception of memory as a form of knowledge. Unlike knowledge, memory implies neither belief nor justification.

I point out that internalist conceptions of belief that have become outmoded in the philosophy of mind are still current in epistemology (or at any rate they were in 2003). I explore the consequences of bringing epistemology up to speed with a more contemporary conception of belief.

“Quality” refers nominatively to a standard of performance. Quality is the central idea that differentiates speech protected by academic freedom (the right to worthwhile utterances) from constitutionally protected speech (the right to say anything at all). Extant documents and discussions state that professional peers determine quality based on norms of a field. But professional peers deem utterances and activities as consonant with quality only in reference to criteria that establish meaning of the term. In the absence of articulation, these criteria (...) are ambiguous. Consequently, there exists recurrent confusion about what faculty members have a defensible right to say and do. This article develops an ontology of quality in reference to higher education teaching, a component of academic careers generally not subject to extensive peer review and where instructors thereby exercise considerable autonomy. The ontology identifies three criteria that bound quality: _constraint, context,_ and _amplitude_. Boundedness exists only insofar as boundaries are controlled. The article examines two types of problems in professional control that affect quality: _slippage_ and _overreach_. Both are instances of organizational deviance and abrogation of professional ethics. It is argued that the patterns threaten the structural integrity and public confidence of faculty, fields, and higher education institutions. (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?

The background of this paper (section 1) consists in a new account to foundation‐theoretic epistemology characterized by two features: (i) All beliefs are to be justified by deductive, inductive or abductive inferences from a minimalistic class of unproblematic (introspective or analytic) basic beliefs. (ii) Higher‐order justifications for these inferences are given by means of the novel method of optimality justifications. Optimality justifications are a new tool for epistemology (section 2). An optimality justification does not attempt todemonstratethat a cognitive method is (...) reliable (which is impossible), but pursues the more modest goal of demonstrating that the method isoptimalamong all accessible alternative methods for the given epistemic goal. The reasoning from the established optimality of a method to the acceptability of a particular belief generated by the method is accomplished by so‐called optimality principles. In sections 3–5, the method of optimality justifications is carried out in detail for three fundamental problems: justifying induction, logic, and theory‐generating abduction. (shrink)

In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

This Open Access book addresses the age-old problem of infinite regresses in epistemology. How can we ever come to know something if knowing requires having good reasons, and reasons can only be good if they are backed by good reasons in turn? The problem has puzzled philosophers ever since antiquity, giving rise to what is often called Agrippa's Trilemma. The current volume approaches the old problem in a provocative and thoroughly contemporary way. Taking seriously the idea that good reasons are (...) typically probabilistic in character, it develops and defends a new solution that challenges venerable philosophical intuitions and explains why they were mistakenly held. Key to the new solution is the phenomenon of fading foundations, according to which distant reasons are less important than those that are nearby. The phenomenon takes the sting out of Agrippa's Trilemma; moreover, since the theory that describes it is general and abstract, it is readily applicable outside epistemology, notably to debates on infinite regresses in metaphysics.

Ünal and Papafragou examine what one might call learning “really hard” meanings, that is, evidentials, which linguistically mark the source of information associated with use of a given verb. They explore the relationship between children’s mastery of the relevant nonlinguistic conceptual underpinnings and the linguistic marking of evidentials, and find that the two kinds of mastery show different developmental trajectories, with the relationship far from one‐to‐one. This case study points to the complex and nuanced relationships between language learning and nonlinguistic (...) understanding in the same domain. (shrink)

This paper revisits a puzzle that arises for theories of knowledge according to which one can know on the basis of merely inductive grounds. No matter how strong such theories require inductive grounds to be if a belief based on them is to qualify as knowledge, there are certain beliefs that are based on even stronger inductive grounds, while, intuitively, they do not qualify as knowledge. This paper discusses what is often regardedas the most promising classical invariantist solution to the (...) puzzle, namely, that beliefs about the outcomes of fair lotteries do not qualify as knowledge because they are too lucky to do so, while other beliefs based on potentially weaker inductive grounds are not too lucky. A case is presented that shows that this solution to the puzzle is actually not viable. It is argued that there is no obvious alternative solution in sight and that therefore the puzzle still awaits a classical invariantist solution. (shrink)

Among epistemologists, it is not uncommon to relate various forms of epistemic luck to the vexed debate between internalists and externalists. But there are many internalism/externalism debates in epistemology, and it is not always clear how these debates relate to each other. In the present paper I investigate the relation between epistemic luck and prominent internalist and externalist accounts of epistemic justification. I argue that the dichotomy between internalist and externalist concepts of justification can be characterized in terms of epistemic (...) luck. Whereas externalist theories of justification are incompatible with veritic luck but not with reflective luck, the converse is true for internalist theories of justification. These results are found to explain and cohere with some recent findings from elsewhere in epistemology, and support a surprising picture of justification, on which internalism and externalism are complementary rather than contradictory positions.

I consider whether evolutionary explanations can debunk our moral beliefs. Most contemporary discussion in this area is centred on the question of whether debunking implications follow from our ability to explain elements of human morality in terms of natural selection, given that there has been no selection for true moral beliefs. By considering the most prominent arguments in the literature today, I offer reasons to think that debunking arguments of this kind fail. However, I argue that a successful evolutionary debunking (...) argument can be constructed by appeal to the suggestion that our moral outlook reflects arbitrary contingencies of our phylogeny, much as the horizontal orientation of the whale’s tail reflects its descent from terrestrial quadrupeds. An introductory chapter unpacks the question of whether evolutionary explanations can debunk our moral beliefs, offers a brief historical guide to the philosophical discussion surrounding it, and explains what I mean to contribute to this discussion. Thereafter follow six chapters and a conclusion. The six chapters are divided into three pairs. The first two chapters consider what contemporary scientific evidence can tell us about the evolutionary origins of morality and, in particular, to what extent the evidence speaks in favour of the claims on which debunking arguments rely. The next two chapters offer a critique of popular debunking arguments that are centred on the irrelevance of moral facts in natural selection explanations. The final chapters develop a novel argument for the claim that evolutionary explanations can undermine our moral beliefs insofar as they show that our moral outlook reflects arbitrary contingencies of our phylogeny. A conclusion summarizes my argument and sets out the key questions that arise in its wake. (shrink)

This paper critically examines Deleuze’s treatment of the Nietzschean problem of nihilism. Of all the major figures in contemporary continental thought, Deleuze is at once one of the most luminous, and practically a lone voice in suggesting that nihilism may successfully be overcome. Whether or not he is correct on this point is thus a commanding question in relation to our understanding of the issue. Many commentators on Nietzsche have argued that his project of overcoming nihilism is destined to failure (...) because of the affinity between the problem of nihilism and the logic of negation. While Nietzsche wants an absolute affirmation of life, Spinoza’s principle that “all determination is negation,” as well as Hegel’s dialectical conception of negation, suggest that affirmation free of negation is not possible. However, some commentators indicate that Deleuze successfully shows how overcoming nihilism is possible because his “logic of difference” allows for an affirmation which is not dialectically reappropriated by negation. This paper argues that beyond such logical considerations, there are metaphysical and existential reasons why Deleuze’s interpretation of nihilism fails to show that it can be overcome. For Deleuze, the overcoming of nihilism hinges not just on a logic of difference, but on a radical interpretation of Nietzsche’s doctrine of eternal return as “selective being.” Drawing on recent scholarship and on Nietzsche’s own writings I argue that this is not a tenable interpretation, and also, more importantly, that the metaphysical and existential implications of this understanding of eternal return reinstate nihilism at the very point where it is supposedly overcome. Moreover, I argue that there are attendant ethical and political dangers to Deleuze’s position on nihilism. (shrink)

This paper develops an analysis of a scalar implicature that is induced by the use of reportative evidentials such as the Cuzco Quechua enclitic = si and the German modal sollen. Reportatives, in addition to specifying the speaker’s source of information for a statement as a report by someone else, also usually convey that the speaker does not have direct evidence for the proposition expressed. While this type of implicature can be calculated using the same kind of Gricean reasoning that (...) underlies other scalar implicatures, it requires two departures from standard assumptions. First, evidential scalar implicatures differ from the more familiar scalar implicatures in that they do not turn on the notion of informativeness but on the notion of evidential strength. Second, the implicature arises on the illocutionary level of meaning. It is argued that a version of Grice’s maxim of quantity in terms of illocutionary strength can account for this evidential scalar implicature as well as for the more typical scalar implicatures. The account developed also proposes some revisions to the taxonomy of speech acts and suggests that the sincerity conditions of assertive speech acts contain an evidential sincerity condition in addition to the belief condition standardly assumed.

This Introduction to the special issue on “Skepticism and Justification” provides a background to the nine articles collected here and a detailed summary of each, which highlights their interconnections and relevance to the debate at the heart of the issue.

The purpose of this paper is to provide an account of the epistemology and metaphysics of universe creation on a computer. The paper begins with F.J.Tipler's argument that our experience is indistinguishable from the experience of someone embedded in a perfect computer simulation of our own universe, hence we cannot know whether or not we are part of such a computer program ourselves. Tipler's argument is treated as a special case of epistemological scepticism, in a similar vein to `brain-in-a-vat' arguments. (...) It is argued that the hypothesis that our universe is a program running on a digital computer in another universe generates empirical predictions, and is therefore a falsifiable hypothesis. The computer program hypothesis is also treated as a hypothesis about what exists beyond the physical world, and is compared with Kant's metaphysics of noumena. It is proposed that a theory about what exists beyond the physical world should be formulated with the precise concepts of mathematics, and should generate physical predictions. It is argued that if our universe is a program running on a digital computer, then our universe must have compact spatial topology, and the possibilities of observationally testing this prediction are considered. The possibility of testing the computer program hypothesis with the value of the density parameter Omega_0 is also analysed. The informational requirements for a computer to represent a universeexactly and completely are considered. Consequent doubt is thrown upon Tipler's claim that if a hierarchy of computer universes exists, we would not be able to know which `level of implementation' our universe exists at. It is then argued that a digital computer simulation of a universe cannot exist as a universe. However, the paper concludes with the acknowledgement that an analog computer simulation can be objectively related to the thing it represents, hence an analog computer simulation of a universe could, in principle, exist as a universe.
