According to epistemic internalism, the only facts that determine the justificational status of a belief are facts about the subject’s own mental states, like beliefs and experiences. Externalists instead hold that certain external facts, such as facts about the world or the reliability of a belief-producing mechanism, affect a belief’s justificational status. Some internalists argue that considerations about evil demon victims and brains in vats provide excellent reason to reject externalism: because these subjects are placed in epistemically unfavorable settings, externalism (...) seems unable to account for the strong intuition that these subjects’ beliefs are nonetheless justified. I think these considerations do not at all help the internalist cause. I argue that by appealing to the anti-individualistic nature of perception, it can be shown that skeptical scenarios provide no reason to prefer internalism to externalism. (shrink)

Fictional truth is commonly analyzed in terms of the speech acts or propositional attitudes of a teller. In this paper, I investigate Lewis’s counterfactual analysis in terms of felicitous narrator assertion, Currie’s analysis in terms of fictional author belief, and Byrne’s analysis in terms of ideal author invitations to make-believe—and find them all lacking. I propose instead an analysis in terms of the revelations of an infelicitous narrator.

I start by reconsidering two familiar arguments against modal realism. The argument from epistemology relates to the issue whether we can infer the existence of concrete objects by a priori means. The argument from pragmatics purports to refute the analogy between the indispensability of possible worlds and the indispensability of unobserved entities in physical science and of numbers in mathematics. Then I present two novel objections. One focusses on the obscurity of the notion of isolation required by modal realism. The (...) other stresses the arbitrary nature of the rules governing the behaviour of Lewisean universes. All four objections attack the reductive analysis of modality that is supposed to be the chief merit of modal realism. (shrink)

A belief is reflectively lucky if it is a matter of luck that the belief is true, given what a subject is aware of on reflection alone. Various epistemologists have argued that any adequate theory of knowledge should eliminate reflective luck, but doing so has proven difficult. This article distinguishes between two kinds of reflective luck arguments in the literature: local arguments and global arguments. It argues that local arguments are best interpreted as demanding, not that one be reflectively aware (...) of the reliability of the sources of one’s beliefs, but that one’s beliefs be attributable to one as one’s own. The article then argues that global arguments make illegitimate demands, because they require that we be ultimately answerable for our beliefs. In the end, the article argues that epistemologists should shift their focus away from reflective luck and toward the conditions under which beliefs are attributable to cognitive agents. (shrink)

Hallucinatory pictures are yet to be found picture-like artifacts that induce a hallucination of their content that cannot be intuitively explained by a look at the structure of the pictorial vehicle. Different accounts of depiction make different predictions about the possibility that such artifacts be considered as pictures. Some cases are presented that point towards the intuitive acceptability of hallucinatory pictures.

I present and defend a unified, non-reductive analysis of the a priori and a posteriori . It is a mistake to remove all epistemic conditions from the analysis of the a priori (as, for example, Alvin Goldman has recently suggested doing). We can keep epistemic conditions (like unrevisability) in the analysis as long as we insist that a priori and a posteriori justification admit of degrees. I recommend making the degree to which a belief’s justification is a priori or a (...) posteriori solely dependent on the revisability relations that obtain among the faculties that deliver the belief and all other faculties.

According to Scott Soames, proper names have no descriptive meaning. Nonetheless, Soames maintains that proper names are typically used to make descriptive assertions. In this paper, I challenge Soames’ division between meaning and what is asserted, first by arguing that competent speakers always make descriptive assertions with name-containing sentences, and then by defending an account of proper name meaning that accommodates this fact.

The publication of Davidson 2001, anthologizing articles from the 1980s and 1990s, encourages reconsidering arguments contained in them. One such argument is Davidson’s omniscient-interpreter argument (‘OIA’) in Davidson 1983. The OIA allegedly establishes that it is necessary that most beliefs are true. Thus the omniscient interpreter, revived in 2001 and now 20 years old, was born to answer the skeptic. In Part I of this paper, I consider charges that the OIA establishes only that it is possible that most beliefs (...) are true; if correct, then it is also possibly the case that most beliefs are false—the skeptic’s very position. Next, I consider two responses on Davidson’s behalf, showing that each fails. In Part II, I show that the OIA establishes neither that it is necessarily merely possibly but actually the case that most beliefs are true. I then conclude that this is enough to answer the skeptic.

Morphological content is information that is implicitly embodied in the standing structure of a cognitive system and is automatically accommodated during cognitive processing without first becoming explicit in consciousness. We maintain that much belief-formation in human cognition is essentially morphological : i.e., it draws heavily on large amounts of morphological content, and must do so in order to tractably accommodate the holistic evidential relevance of background information possessed by the cognitive agent. We also advocate a form of experiential evidentialism concerning (...) epistemic justification—roughly, the view that the justification-status of an agent’s beliefs is fully determined by the character of the agent’s conscious experience. We have previously defended both the thesis that much belief-formation is essentially morphological, and also a version of evidentialism. Here we explain how experiential evidentialism can be smoothly and plausibly combined with the thesis that much of the cognitive processing that generates justified beliefs is essentially morphological. The leading idea is this: even though epistemically relevant morphological content does not become explicit in consciousness during the process of belief-generation, nevertheless such content does affect the overall character of conscious experience in an epistemically significant way: it is implicit in conscious experience, and is implicitly appreciated by the experiencing agent.

In this paper, I examine an account of instrumental reasoning recently put forth by John Broome. His key suggestion is that anyone who engages in reasoning about his intentions also believes that he will do what he intends to do and that combined with a belief about necessary means this creates rational pressure towards believing that one will take the necessary means. I argue that Broome’s model has three significant problems; his key premise is false—the sincere expression of an intention (...) does not entail the belief that one will successfully execute that intention; his account yields a model of instrumental reasoning that is uncomfortably reflective; he seems unable to explain the rational pressure towards taking necessary means that arises directly from having an end and an instrumental belief. All three problems, I argue, are a consequence of Broome’s inadequate position on what it is to intend to do something. (shrink)

Armstrong’s combinatorial theory of possibility faces the obvious difficulty that not all universals are compatible. In this paper I develop three objections against Armstrong’s attempt to account for property incompatibilities. First, Armstrong’s account cannot handle incompatibilities holding among properties that are either simple , or that are complex but stand to one another in the relation of overlap rather than in the part/ whole relation. Secondly, at the heart of Armstrong’s account lies a notion of structural universals which, building on (...) an objection by David Lewis, is shown to be incoherent. I consider and reject two alternative ways of construing the composition of structural universals in an attempt to meet Lewis’ objection. An important consequence of this is that all putative structural properties are in fact simple . Finally, I argue that the quasi-mereological account presupposes modality in a way that undermines the reductionist aim of the combinatorialist theory of which it is a central part. I conclude that Armstrong’ quasi-mereological account of property incompatibility fails. Without that account, however, Armstrong’s combinatorial theory either fails to get off the ground, or else must give up its goal of reducing the notion of possibility to something non-modal.

The aim of the paper is to state a version of epistemic expressivism regarding knowledge, and to suggest how this expressivism about knowledge explains the value of knowledge. The paper considers how an account of the value of knowledge based on expressivism about knowledge responds to the Meno Problem, the Swamping Problem, and a variety of other questions that pertains to the value of knowledge, and the role of knowledge in our cognitive ecology.

According to a standard picture, for any two comparable objects and a basis for comparison, either one is greater than the other or they are equal with respect to the basis. This picture has been called the Trichotomy Thesis, and although it is intuitive and plausible, it has been called into question by such philosophers as Derek Parfit, James Griffin, Joseph Raz, and Ruth Chang. Chang’s discussion is particularly rich, for she proposes and provides a detailed account of a possible (...) fourth relation that, she argues, provides a satisfying explanation of hard cases of comparison. In this paper, I will examine a version of the main argument against the Trichotomy Thesis and attempt to show that it is unsound. (shrink)

The notion that exploitation consists in taking wrongful advantage of another’s vulnerability is widespread in the philosophical literature. Considering the popularity of this view, it is disappointing to find that very few authors attempt to provide substantive accounts of characteristics they consider relevant vulnerabilities (i.e., those pertinent to exploitation), as well as of relevant features which make taking advantage of those vulnerabilities wrongful. In this paper, I analyze the few approaches (notably those presented by Ruth Sample and Robert Goodin) that (...) in fact provide such accounts, and I examine whether and how they pertain to exploitation in general, as well as to exploitation in more personal/intimate relationships. I conclude that these vulnerability-based accounts of exploitation are either too vague or too restrictive, since they tend to leave out many instances of exploitation (especially those within personal and intimate relationships), and are as such inadequate.

Four variations on Two Envelope Paradox are stated and compared. The variations are employed to provide a diagnosis and an explanation of what has gone awry in the paradoxical modeling of the decision problem that the paradox poses. The canonical formulation of the paradox underdescribes the ways in which one envelope can have twice the amount that is in the other. Some ways one envelope can have twice the amount that is in the other make it rational to prefer the (...) envelope that was originally rejected. Some do not, and it is a mistake to treat them alike. The nature of the mistake is diagnosed by the different roles that rigid designators and definite descriptions play in unproblematic and in untoward formulations of decision tables that are employed in setting out the decision problem that gives rise to the paradox. The decision maker’s knowledge or ignorance of how one envelope came to have twice the amount that is in the other determines which of the different ways of modeling his decision problem is correct. Under this diagnosis, the paradoxical modeling of the Two Envelope problem is incoherent. (shrink)

An objection is presented to Lewis’s analysis of counterfactual conditionals in terms of relative closeness of possible worlds. The objection depends on no special assumptions about the ‘closer-than’ relation. The argument also casts doubt on Lewis’s claim that Antecedent Strengthening fails for counterfactuals.

The metaphysical dispute between moral realists and antirealists is cast in terms of properties: the realist holds that moral properties exist, the antirealist denies this claim. There is a longstanding philosophical dispute over the nature of properties, and the obscurity of properties may make the realist/antirealist dispute even more obscure. In the spirit of deflationary theories of truth, we can turn to a deflationary theory of properties in order to clarify this issue. One might reasonably worry that such an account (...) of properties would not be capable of properly characterizing disputes regarding the existence or nonexistence of genuine moral properties. In this paper, I will show that, within this framework, the traditional disputes over the existence of moral properties can be characterized in a far clearer fashion than is usually the case. A deflationary account of properties, along with an explanatory hierarchy of properties, makes the dispute in ontology clear. (shrink)

The paper defends causal explanationism concerning our modal intuitions and judgments, and, in particular, the following claims. If a causally explainable mirroring or “pre-established harmony” between our mind and modal reality obtains, we are justified in believing it does. We do not hold our modal beliefs compulsively and blindly but with full subjective and objective justification. Therefore, causal explanation of our modal beliefs does not undermine rational trust in them. Explanation and trust support each other. In contrast, anti-explanationists (from Kant, (...) through neo-wittgensteinians to T. Nagel and J. Pust), claim that causal explanation of intuitions and judgments undermines rational trust in them. They especially target causal explanation in terms of pre-established harmony between our mind, shaped by causal processes, and the underlying modal structure of reality. The paper argues against them. The argument builds upon the claim that the appeal to modal facts is indispensable for systematization and explanation of non-modal ones. Therefore, we should assume that modal facts exist and are not disjoint and isolated from actual facts. The modal structure of the universe intervenes in the non-modal reality. Causal processes indirectly carry information about deep modal structure. Any (reasonable candidate) causal explanation of our intuitional modal beliefs should start from this indirect contact with and information about modal facts. Therefore, if our intuitional modal beliefs are true and causally explainable (by a factual, non-modal explanans), they are true in virtue of the deep underlying modal structure. They are sensitive to modal reality and track it. We can come to know this fact, and thus strengthen our spontaneous trust in our modal intuitions. (shrink)

Children learn and come to know things about the world at a very young age through the testimony of their caregivers. The challenge comes in explaining how children acquire such knowledge. Since children indiscriminately receive testimony, their testimony-based beliefs seem unreliable, and, consequently, should fail to qualify as knowledge. In this paper I discuss some attempted explanations by Sandy Goldberg and John Greco and argue that they fail. I go on to suggest that what generates the problem is a hidden (...) assumption that the standards for testimonial knowledge are invariant between children and cognitively mature adults. I propose that in order to adequately explain how children acquire testimonial knowledge we should reject this hidden assumption. I then argue that understanding knowledge in terms of intellectual skills gives us a plausible framework to do so. (shrink)

Wittgenstein’s language games can be put into a wider service by virtue of elements they share with some contemporary opinions concerning logic and the semantics of computation. I will give two examples: manifestations of language games and their possible variations in logical studies, and their role in some of the recent developments in computer science. It turns out that the current paradigm of computation that Girard termed Ludics bears a striking resemblance to members of language games. Moreover, the kind of (...) interrelations that are emerging could be scrutinised from the viewpoint of logic that virtually necessitates game-theoretic conceptualisations, demonstrating the fact that the meaning of utterances may, in many situations, be understood as Wittgenstein’s language games of ‘showing or telling what one sees’. This provides motivation for the use of games in relation to logic and formal semantics that some commentators have called for. Many of the ideas can be traced to C.S. Peirce, for whom signs were vehicles of strategic communication. The conclusion about Wittgenstein is that the notions of saying and showing converge in his late philosophy. (shrink)

When discussing the distinction between referential and attributive uses of definite descriptions, Keith Donnellan also mentions cases such as ‘Smith’s murderer is insane’, uttered in a scenario in which Smith committed suicide. In this essay, I defend a two-fold thesis: (i) the alleged intuition that utterances of ‘Smith’s murderer is insane’ are true in the scenario in question is independent from the phenomenon of referential uses of definite description, and, most importantly, (ii) even if such intuition is granted semantic relevance, (...) the evidence it presents is compatible with a Russellian treatment of definite descriptions. I thus present a Russellian analysis of ‘Smith’s murderer is insane’ which, when coupled with certain independently plausible hypotheses, explains the presumed intuition that certain utterances of this sentence are indeed true, at least as long as the intended individual is insane.

Coherentists on epistemic justification claim that all justification is inferential, and that beliefs, when justified, get their justification together (not in isolation) as members of a coherent belief system. Some recent work in formal epistemology shows that “individual credibility” is needed for “witness agreement” to increase the probability of truth and generate a high probability of truth. It can seem that, from this result in formal epistemology, it follows that coherentist justification is not truth-conducive, that it is not the case (...) that, under the requisite conditions, coherentist justification increases the probability of truth and generates a high probability of truth. I argue that this does not follow. (shrink)

Using Carnap’s concept explication , we propose a theory of concept formation in mathematics. This theory is then applied to the problem of how to understand the relation between the concepts formal proof ( deduction ) and informal, mathematical proof.

A prominent contemporary anti-skeptical strategy, most famously articulated by Keith DeRose, aims to cage the skeptic′s doubts by contextualizing subjunctive conditional accounts of knowledge through a conversational rule of sensitivity. This strategy, I argue, courts charges of circularity by selectively invoking heavy counterfactual machinery. The reason: such invocation threatens to utilize a metric for modal comparison that is implicitly informed by judgments of epistemic sameness. This gives us reason to fear that said modal metric is selectively cherry-picked in advance to (...) support the very anti-skeptical conclusion for which the contextualist longs. (shrink)

What role can intellectual virtues play in an account of knowledge when we interpret those virtues internalistically, i.e., as depending only on internal states of the cognizer? Though it has been argued that internalist virtues are ill suited to play any role in an account of knowledge, I will show that, on the contrary, internalist virtues can play an important role in recent accounts of knowledge developed to utilize externalist virtues. The virtue account of knowledge developed by Linda Zagzebski is (...) intended to be supplemented by her version of the intellectual virtues which require an external success component. John Greco and Wayne Riggs both develop credit accounts of knowledge on which the abilities we use when we get credit for a true belief must be reliable. I examine the similarities between these three accounts of knowledge and demonstrate that internalist virtues fit into these accounts just as well as externalist virtues. Thus, although internalist virtues do not require a reliable connection to truth, they can still play an important role in defining the truth-requiring concept of knowledge. (shrink)
