This paper argues that Epistemic Contextualism, Knowledge Closure, and the Knowledge Account of Assertion are inconsistent. The argument is developed by considering an objection to Contextualism that is unsuccessful. Some Contextualist responses are canvassed and rejected. Finally, it is argued that an analogue of the inconsistency arises for those who accept that justification is closed under known entailment.

One strategy for dealing with apparent cases of knowledge from falsehood is to deny that the knowledge actually is from a falsehood. Those endorsing such a move have suggested that cases of knowledge from falsehood are instead cases of knowledge despite falsehood. We here provide a dilemma for those wanting to reject the possibility of knowledge from falsehood. The dilemma is explained in part by examining recent attempts to deny that knowledge can be inferentially derived from falsehood.

A challenge has recently been levelled against the legal and/or moral legitimacy of some advance directives. It has been argued that in certain cases an advance directive carries no weight in a decision on whether to withhold treatment, since the individual in the debilitating state is not the same person as the person who created the advance directive. In the first section of this paper, I examine two formulations of the argument against the moral legitimacy of the advance directives under (...) review. The second section reviews, and criticizes, an objection to such arguments. In the penultimate section, possible models supporting the viability of the advance directives are considered. The final section makes good on an obligation incurred by the title of the paper. (shrink)

Bishop Butler objected to Locke's theory of personal identity on the grounds that memory presupposes personal identity. Most of those sympathetic with Locke's account have accepted Butler's criticism, and have sought to devise a theory of personal identity in the spirit of Locke's that avoids Butler's circularity objection. John McDowell has argued that even the more recent accounts of personal identity are vulnerable to the kind of objection Butler raised against Locke's own account. I criticize McDowell's stance, drawing on a (...) distinction introduced by Annalisa Coliva between two types of immunity to error through misidentification. (shrink)

Some of the concerns that have been raised in connection to the use of advance directives are of the epistemic variety. Such concerns highlight the possibility that adhering to an advance directive may conflict with what the author of the directive actually wants at the time of treatment. However, at least one objection to the employment of advance directives is metaphysical in nature. The objection to be discussed here, first formulated by Rebecca Dresser and labeled by Allen Buchanan as the (...) slavery argument and David DeGrazia the someone else problem, aims to undermine the legitimacy of certain uses of advance directives by concluding that such uses rest upon an incorrect assumption about the identity over time of those ostensibly governed by the directives. There have been numerous attempts to respond to this objection. This paper aims to assess two strategies that have been pursued to cope with the problem. (shrink)

We begin by discussing some logical constraints on the psychological approach to personal identity. We consider a problem for the psychological approach that arises in fission cases. The problem engenders the need for a non-branching clause in a psychological account of the co-personality relation. We look at some difficulties in formulating such a clause. We end by rejecting a recently proposed formulation of non-branching. Our criticism of the formulation raises some interesting questions about the individuation of person stages.

Derek Parfit has offered numerous arguments in an attempt to establish that identity is not what matters. Jens Johannson has recently argued that Parfit's various arguments for the claim that identity is not what matters fail to establish what Parfit takes such arguments to establish. Johannson contends that this is due in part to the invalidity of one of Parfit's key arguments, and the fact that Parfit ignores a position that is compatible with the conclusions of his successful arguments and (...) the claim that identity is in fact what matters, namely, that I survive fission as either one of the fission products or the other, but it is indeterminate which one I survive as. I aim to establish here that both of Johannson's assertions are problematic. As a corollary of this task, I hope to shed some light on the relationship between indeterminacy and fission-based arguments for the claim that identity is not what matters. (shrink)

This article is a response to an important objection that Sherrilyn Roush has made to the standard closure-based argument for skepticism, an argument that has been studied over the past couple of decades. If Roush's objection is on the mark, then this would be a quite significant finding. We argue that her objection fails.

_ Source: _Volume 5, Issue 1, pp 55 - 60 Peter Murphy has argued that effective skeptical scenarios all have the following feature: the subject involved in the scenario does not know that some ordinary proposition is true, even if the proposition is true in the scenario. So the standard “false belief” conception of skeptical scenarios is wrong, since the belief of the targeted proposition need not be mistaken in the scenario. Murphy then argues that this observation engenders a problem (...) for skeptical arguments: they require the KK principle. We respond to this criticism on behalf of the skeptic in our paper.

Lynne Rudder Baker’s Constitution View of human persons has come under much recent scrutiny. Baker argues that each human person is constituted by, but not identical to, a human animal. Much of the critical discussion of Baker’s Constitution View has focused upon this aspect of her account. Less has been said about the positive diachronic account of personal identity offered by Baker. Baker argues that it is sameness of what she labels ‘first-person perspective’ that is essential to understanding personal identity (...) over time . Baker claims that her account avoids the commitment to indeterminacy of personal identity entailed by the psychological account. Further, the psychological account, but not her account, is plagued by what Baker labels the ‘duplication problem’. In the end, I argue that neither of these considerations forces us to renounce the psychological account and adopt Baker’s favored account. (shrink)

The nature of perceptual demonstratives, the ‘that F’ component of judgments of the form ‘that F is G’ based on perceptual input, has been a topic of interest for many philosophers. Another related, though distinct, question concerns the nature of demonstrative judgments based not on current perceptual input, but instead derived from memory. I argue that the account put forward by John Campbell fails to adequately account for memory-based demonstrative thought.

Those who endorse a knowledge-first program in epistemology claim that rather than attempting to understand knowledge in terms of more fundamental notions or relations such as belief and justification, we should instead understand knowledge as being in some sense prior to such concepts and/or relations. If we suppose that this is the correct approach to theorizing about knowledge, we are left with a residual question about the nature of those concepts or relations, such as justification, that were thought to be (...) first but are now second. Jonathan Jenkins Ichikawa has recently proposed that we understand justification in terms of potential knowledge. Ichikawa combines his view of knowledge and justification with what initially seems to be a natural complement, epistemological disjunctivism. While Ichikawa focuses on hallucination, I shift the focus to illusion. I argue that the combination of justification as potential knowledge and epistemological disjunctivism entails that perceptual beliefs that arise from illusions are not justified. (shrink)

Hamid Vahid criticizes Tyler Burge's account of perceptual entitlement. Vahid argues that Burge's account fails to satisfy a criterion of adequacy that any correct account of perceptual warrant must satisfy. According to Vahid, a correct account of perceptual warrant must allow for perceptual beliefs which are produced by a properly functioning perceptual system yet which lack warrant. The present article argues that Vahid's critique of Burge fails. It presents numerous examples of such beliefs that are consistent with Burge's account of (...) perceptual entitlement. (shrink)

There is an apparent problem stemming from the factivity of knowledge that seems to afflict both contextualism and subject-sensitive invariantism . 1 In this article, we will first explain how the problem arises for each theory, and then we will propose a uniform resolution.1. The factivity problem for contextualismLet K t stands for X knows _ at t. Let h stand for S has hands. According to contextualism, ‘K t’ is true as uttered in some ordinary conversational contexts. Let O (...) be such a context. So we have ‘K t’ is true in O.Consider a demanding conversational context D . Let S* be a participant in D. We have ‘K t’ is not true in D.In prose: ‘S* knows at t that S has hands’ is not true in D. 2 , 3 Let us suppose that S* has a favourable epistemic status with respect to , as follows: ‘K t[S*,‘K t’ is true in O]’ is true in D. says that a certain sentence about S*'s epistemic status at t is true in D. S*'s epistemic status with respect to which proposition? A certain metalinguistic proposition concerning the truth in O of the sentence ‘K t’. That sentence in turn concerns S's epistemic status at t with respect to the proposition that S has hands. Got it? 4The factivity of ‘knows’ yields the following consequence : ‘K t’ is true in O → hThis metalinguistic factivity claim is licensed by the fact that any sentence of the …. (shrink)

We consider one of Eric Olson's chief arguments for animalism about personal identity: the view that we are each identical to a human animal. The argument was originally given in Olson's book The Human Animal . Olson's argument presupposes an epistemological premise which we examine in detail. We argue that the premise is implausible and that Olson's defense of animalism is therefore in trouble.

Kelly Becker has argued that in an externalist anti-luck epistemology, we must hold that knowledge requires the satisfaction of both a modalized tracking condition and a process reliability condition. We raise various problems for the examples that are supposed to establish this claim.

Dylan Dodd offers a simple, yet forceful, argument for infallibilism. The argument relies upon two assumptions concerning the relationship between knowledge, epistemic possibility, and epistemic probability. We argue below that by endorsing a particular conception of epistemic possibility, a fallibilist can both plausibly reject one of Dodd’s assumptions and mirror the infallibilist’s explanation of the linguistic data. In fact, such a fallibilist may even be able to offer a more comprehensive explanation than the infallibilist. Our discussion is of interest due (...) in part to the fact that many fallibilists have rejected the conception of epistemic possibility employed in our response to Dodd. (shrink)

In ”Incompatibilism and the Past,” Andrew Bailey engages in a thorough investigation of what he calls the "No Past Objection" to arguments for incompatibilism.This is an objection that stems from the work of Joseph Keim Campbell and that has generated an Interesting literature. Bailey ends by offering his own answer to the No Past Objection by giving his own argument for incompatibilism, an argument that he claims to be immune to the objection. We have some observations to make regarding what (...) we take to be Bailey's answer to the objection (all of whose details are left to the reader – we attempt to fill this lacuna). (shrink)

In an earlier paper, I presented a novel objection to closure-based skeptical arguments. There I argued that the best account of what makes skeptical scenarios effective cripples the closure-based skeptical arguments that use those scenarios. On behalf of the skeptic, Christopher Buford and Anthony Brueckner have replied to my objection. Here I review my original argument, criticize their replies, and highlight two important issues for further investigation.

In an age where issues like climate change and the unintended consequences of technological innovation are high on the ethical and political agenda, questions about the nature and extent of our responsibilities to future generations have never been more important, yet simultaneously so difficult to answer. This book takes a unique approach to the problem by drawing on diverse traditions of thinking about care (including developmental psychology, phenomenology and feminist ethics) to explore the nature and meaning of our relationship with (...) the future. Demonstrating that many influential perspectives on intergenerational ethics, including positions advanced by John Rawls, Brian Barry, and Ulrich Beck are undermined by problems relating to uncertainty, it shows that an approach based on care ethics can confront the uncertain future successfully and give a viable account of the nature and scope of future-oriented responsibilities.

Suppose we believe that God created the world. Then surely we want it to be the case that he intended, in some sense at least, to create THIS world. Moreover, most theists want to hold that God didn't just guess or hope that the world would take one course or another; rather, he KNEW precisely what was going to take place in the world he planned to create. In particular, of each person P, God knew that P was to exist. (...) Call this the "standard" conception. Most theists find the standard conception appealing. Unfortunately, the view seems to conflict with the equally appealing idea — call it "temporal actualism" — that there are no "future" individuals beyond those that already exist in the present moment. For, on this view, for any historical person P, prior to creation, there was no such person as P and hence nothing about P for God to know. Hence, in particular, God couldn't have known that P was to exist. This is of course not a new problem. But past solutions to it are highly problematic. In this paper, after canvassing previous approaches, I will propose a solution that seems to preserve both temporal actualism and a suitably robust form of the standard conception while avoiding the pitfalls of the past.

Aristotle attaches particular significance to the homonymy of many central concepts in philosophy and science: that is, to the diversity of ways of being common to a single general concept. His preoccupation with homonymy influences his approach to almost every subject that he considers, and it clearly structures the philosophical methodology that he employs both when criticizing others and when advancing his own positive theories. Where there is homonymy there is multiplicity: Aristotle aims to find the order within this multiplicity, (...) and believes that doing so is crucial to scientific inquiry and philosophical progress.Christopher Shields investigates and evaluates Aristotle's approach to questions about homonymy, characterizing the metaphysical and semantic commitments necessary to establish the homonymy of a given concept. Then, in a series of case-studies, Shields examines in detail some of Aristotle's principal applications of homonymy--to the body, sameness and oneness, life, goodness, and being. Shields's aim is not only to give a fuller understanding of Aristotle's methodology and to illuminate his specific doctrines in a variety of areas, but to show that this methodology remains fruitful today.

In "Imaging or Imagining? A Neuroethics Challenge Informed by Genetics," Judy Illes and Eric Racine argue that "traditional bioethics analysis" (TBA) is insufficient to deal with moral and metaphysical challenges endemic to recent developments in neuroscience, apparently because they believe that these developments differ in kind, not merely degree, from previous developments. This article suggests that recent neuroscientific developments do not have any metaphysical implications that pose the sort of challenge with which Illes and Racine are concerned. Illes and Racine's (...) view fails because of two faulty metaphysical assumptions: first, the assumption that the mind is the brain; and second, the assumption that neurotechnology has implications for questions related to personal identity.

Moral error theories are often rejected by appeal to ‘companions in guilt’ arguments. The most popular form of companions in guilt argument takes epistemic reasons for belief as a ‘companion’ and proceeds by analogy. I show that this strategy fails. I claim that the companions in guilt theorist must understand epistemic reasons as evidential support relations if her argument is to be dialectically effective. I then present a dilemma. Either epistemic reasons are evidential support relations or they are not. If (...) they are not, then the companions in guilt argument fails. If they are, then a reduction of epistemic reasons to evidential support relations becomes available and, consequently, epistemic reasons cease to be a viable ‘companion’ for moral reasons. I recommend this structure of argument over existing strategies within the literature and defend my claims against recent objections from companions in guilt theorists. (shrink)

What is Plato attempting to accomplish in the Laches? A cursory reading leaves one with the strong impression that the main topic of discussion is the education of the sons of Lysimachus and Melesias. However, an equally cursory survey of the major interpretations of the Laches reveals that few, if any, scholars agree with that impression. Their view is that the main topic of conversation in the Laches is courage, the examination of which takes place in the second main section (...) of the dialogue. On this view, neither the first half of the dialogue nor the concluding short section is philosophically significant since neither adds to the discussion of courage. What is left obscure on that view is what Plato is doing in these “insignificant” sections. In addition, that view does not help us to understand Plato’s emphasis on education throughout the dialogue. It seems, then, that the initial question has led to a second one: is the Laches a unity both philosophical, and philologically? Both of these questions are inextricably intertwined. The question of the unity of the Laches can be dealt with fully through a consideration of a unifying theme or argument, and the question of the integrating theme can be considered only in the light of the structure of the dialogue. I contend that a unifying thread of argument can be found in the Laches and that the traditional view of the dialogue results in cutting it into two parts having little philosophical or literary relation to each other. I propose, first, to show that the traditional interpretation is untenable, and second, to offer a counterinterpretation which avoids the necessity of regarding the first and concluding parts of the dialogue as philosophically insignificant and which provides a unifying theme. These two goals will be achieved in the following way: it will be shown that the assumption that the main conversation of the Laches is about courage implies the destruction of the unity of the Laches and leaves unclear what Plato is doing in the first half of the dialogue. And, second, a counterinterpretation will be offered showing that the central theme of the dialogue is the educational consultant. It will be shown that this theme unifies the dialogue, makes clear what Plato is doing in otherwise obscure passages, and puts into proper perspective the discussion of courage. We must now consider the traditional interpretation of the Laches. (shrink)

The paper provides a systematic overview of recent debates in epistemology and philosophy of science on the nature of understanding. We explain why philosophers have turned their attention to understanding and discuss conditions for “explanatory” understanding of why something is the case and for “objectual” understanding of a whole subject matter. The most debated conditions for these types of understanding roughly resemble the three traditional conditions for knowledge: truth, justification and belief. We discuss prominent views about how to construe these (...) conditions for understanding, whether understanding indeed requires conditions of all three types and whether additional conditions are needed.

Miranda Fricker's important study of epistemic injustice is focussed primarily on testimonial injustice and hermeneutic injustice. It explores how agents' capacities to make assertions and provide testimony can be impaired in ways that can involve forms of distinctively epistemic injustice. My paper identifies a wider range of forms of epistemic injustice that do not all involve the ability to make assertions or offer testimony. The paper considers some examples of some other ways in which injustice can prevent someone from participating (...) in inquiry. (shrink)

The literature on the nature of understanding can be divided into two broad camps. Explanationists believe that it is knowledge of explanations that is key to understanding. In contrast, their manipulationist rivals maintain that understanding essentially involves an ability to manipulate certain representations. The aim of this paper is to provide a novel knowledge based account of understanding. More specifically, it proposes an account of maximal understanding of a given phenomenon in terms of fully comprehensive and maximally well-connected knowledge of (...) it and of degrees of understanding in terms of approximations to such knowledge. It is completed by a contextualist semantics for outright attributions of understanding according to which an attribution of understanding is true of one just in case one knows enough about it to perform some contextually determined task. It is argued that this account has an edge over both its explanationist and manipulationist competitors. (shrink)

Do famous athletes have special obligations to act virtuously? A number of philosophers have investigated this question by examining whether famous athletes are subject to special role model obligations (Wellman 2003; Feezel 2005; Spurgin 2012). In this paper we will take a different approach and give a positive response to this question by arguing for the position that sport and gaming celebrities are ‘ambassadors of the game’: moral agents whose vocations as rule-followers have unique implications for their non-lusory lives. According (...) to this idea, the actions of a game’s players and other stakeholders—especially the actions of its stars—directly affect the value of the game itself, a fact which generates additional moral reasons to behave in a virtuous manner. We will begin by explaining the three main positions one may take with respect to the question: moral exceptionalism, moral generalism, and moral exemplarism. We will argue that no convincing case for moral exemplarism has thus far been made, which gives us reason to look for new ways to defend this position. We then provide our own ‘ambassadors of the game’ account and argue that it gives us good reason to think that sport and game celebrities are subject to special obligations to act virtuously.

According to commonsense psychology, one is conscious of everything that one pays attention to, but one does not pay attention to all the things that one is conscious of. Recent lines of research purport to show that commonsense is mistaken on both of these points: Mack and Rock (1998) tell us that attention is necessary for consciousness, while Kentridge and Heywood (2001) claim that consciousness is not necessary for attention. If these lines of research were successful they would have important (...) implications regarding the prospects of using attention research to inform us about consciousness. The present essay shows that these lines of research are not successful, and that the commonsense picture of the relationship between attention and consciousness can be. (shrink)

According to the snapshot view of temporal experience, instances of movement and change cannot, strictly speaking, be objects of sensory perception. Perceptual consciousness instead consists of a succession of individual momentary experiences, none of which is itself an experience of movement or change. The snapshot view is often presented as an intuitively appealing view of the nature of temporal experience, even by philosophers who ultimately reject it. Yet, it is puzzling how this can be so, given that its central claim (...) – that we can never just perceive things moving or changing – clearly flies in the face of our common sense view of the phenomenology of experience. In this paper, I offer a diagnosis of how it is possible that the deep conflict between the snapshot view and our phenomenological intuitions can sometimes go unnoticed. The materials for this diagnosis can, I think, be found in some passages in Thomas Reid’s Essays on the Intellectual Powers of Man, in which he criticises John Locke’s account of the origins of the idea of succession, as presented in chapter 14 of book II of An Essay Concerning Human Understanding. As I argue, a crucial aspect of Reid’s criticisms can be seen to turn on the idea that Locke fails to distinguish between two quite different variants of the snapshot view, which I call the memory theory and the mirroring theory of temporal experience, respectively. It is the failure to distinguish between these two different variants of the snapshot view, I suggest, that can also make the snapshot view appear more compatible with our phenomenological intuitions than it in fact is.

W. V. Quine famously defended two theses that have fallen rather dramatically out of fashion. The first is that intensions are “creatures of darkness” that ultimately have no place in respectable philosophical circles, owing primarily to their lack of rigorous identity conditions. However, although he was thoroughly familiar with Carnap’s foundational studies in what would become known as possible world semantics, it likely wouldn’t yet have been apparent to Quine that he was fighting a losing battle against intensions, due in (...) large measure to developments stemming from Carnap’s studies and culminating in the work of Kripke, Hintikka, and Bayart. These developments undermined Quine’s crusade against intensions on two fronts. First, in the context of possible world semantics, intensions could after all be given rigorous identity conditions by defining them (in the simplest case) as functions from worlds to appropriate extensions, a fact exploited to powerful and influential effect in logic and linguistics by the likes of Kaplan, Montague, Lewis, and Cresswell. Second, the rise of possible world semantics fueled a strong resurgence of metaphysics in contemporary analytic philosophy that saw properties and propositions widely, fruitfully, and unabashedly adopted as ontological primitives in their own right. This resurgence — happily, in my view — continues into the present day. -/- For a time, at any rate, Quine experienced somewhat better success with his second thesis: that higher-order logic is, at worst, confused and, at best, a quirky notational alternative to standard first-order logic. However, Quine notwithstanding, a great deal of recent work in formal metaphysics transpires in a higher-order logical framework in which properties and propositions fall into an infinite hierarchy of types of (at least) every finite order. Initially, the most philosophically compelling reason for embracing such a framework since Russell first proposed his simple theory of types was simply that it provides a relatively natural explanation of the paradoxes. However, since the seminal work of Prior there has been a growing trend to consider higher-order logic to be the most philosophically natural framework for metaphysical inquiry, many of the contributors to this volume being among the most important and influential advocates of this view. Indeed, this is now quite arguably the dominant view among formal metaphysicians. -/- In this paper, and against the current tide, I will argue in §1 that there are still good reasons to think that Quine’s second battle is not yet lost and that the correct framework for logic is first-order and type-free — properties and propositions, logically speaking, are just individuals among others in a single domain of quantification — and that it arises naturally out of our most basic logical and semantical intuitions. The data I will draw upon are not new and are well-known to contemporary higher-order metaphysicians. However, I will try to defend my thesis in what I believe is a novel way by suggesting that these basic intuitions ground a reasonable distinction between “pure” logic and non-logical theory, and that Russell-style semantic paradoxes of truth and exemplification arise only when we move beyond the purely logical and, hence, do not of themselves provide any strong objection to a type-free conception of properties and propositions. -/- Most of my arguments in §1 are largely independent of any specific account of the nature of properties and propositions beyond their type-freedom. However, I will in addition argue that there are good reasons to take propositions, at least, to be very fine-grained. My arguments are thus bolstered significantly if it can be shown that there are in fact well-defined examples of logics that are not only type-free but which comport with such a conception of propositions. It is the purpose of §2 to lay out a logic of this sort in some detail, drawing especially upon work by George Bealer and related work of my own. With the logic in place, it will be possible to generalize the line of argument noted above regarding Russell-style paradoxes and, in §3, apply it to two propositional paradoxes — the Prior-Kaplan paradox and the Russell-Myhill paradox — that are often taken to threaten the sort of account developed here.
