We very often grant that a person can gain knowledge on the basis of epistemic artifacts such as telescopes, microscopes and so on. However, this intuition threatens to undermine virtue reliabilism according to which one knows that p if and only if one’s believing the truth that p is the product of a reliable cognitive belief-forming process; in an obvious sense epistemic artifacts are not parts of one’s overall cognitive system. This is so, unless the extended cognition hypothesis (HEC) is (...) true. According to HEC when parts of the environment become properly coupled to the agent’s brain then they too can be considered constitutive parts of the overall cognitive mechanism—i.e. cognition potentially extends to the world surrounding the agent. Interestingly, HEC and the broader framework of virtue reliabilism share some intriguing similarities, which render these two views mutually supportive. Making these similarities explicit provides a principled account of the way in which our knowledge-conducive cognitive characters may extend beyond our natural cognitive capacities by incorporating epistemic artifacts.

Several philosophers have recently argued that disagreement with others undermines or precludes epistemic justification for our opinions about controversial issues. This amounts to a fascinating and disturbing kind of intellectual scepticism. A crucial piece of the sceptical argument, however, is that our opponents on such topics are epistemic peers. In this paper, I examine the reasons for why we might think that our opponents really are such peers, and I argue that those reasons are either too weak or too strong, (...) implying absurd conclusions. Thus, there is not a compelling case for disagreement-based intellectual scepticism. (shrink)

Modal knowledge accounts that are based on standards possible-worlds semantics face well-known problems when it comes to knowledge of necessities. Beliefs in necessities are trivially sensitive and safe and, therefore, trivially constitute knowledge according to these accounts. In this paper, I will first argue that existing solutions to this necessity problem, which accept standard possible-worlds semantics, are unsatisfactory. In order to solve the necessity problem, I will utilize an unorthodox account of counterfactuals, as proposed by Nolan, on which we also (...) consider impossible worlds. Nolan’s account for counterpossibles delivers the intuitively correct result for sensitivity i.e. S’s belief is sensitive in intuitive cases of knowledge of necessities and insensitive in intuitive cases of knowledge failure. However, we acquire the same plausible result for safety only if we reject his strangeness of impossibility condition and accept the modal closeness of impossible worlds. In this case, the necessity problem can be analogously solved for sensitivity and safety. For some, such non-moderate accounts might come at too high a cost. In this respect, sensitivity is better off than safety when it comes to knowing necessities. (shrink)

I believe that Tom is the proud father of a baby boy. Why do I think his child is a boy? A natural answer might be that I remember that his name is ‘Owen’ which is usually a boy’s name. Here I’ve given information that might be part of a causal explanation of my believing that Tom’s baby is a boy. I do have such a memory and it is largely what sustains my conviction. But I haven’t given you just (...) any causally relevant information, I’ve given my grounds for my belief. I’ve given reasons that might justify me in supposing that Tom’s baby is a boy. Less naturally, the question might be taken as a request for a broader causal explanation of my holding this belief. Appropriate answers might cite all manner of facts concerning the evolution of the human race, why I chose to pursue philosophy and hence came to know Tom, the mechanisms of email transmission, the firing of various neurons, the circumstances of concept formation as a result of which I’m able to grasp the thought that Tom’s baby is a boy, and so on. It is an interesting question what distinguishes the narrower set of answers that I first suggested. I won’t pursue that here. I assume you have a good enough sense of the distinction I’m drawing. We might call the narrower set of answers justifying reasons, the kind of reasons I might cite in justifying my belief. Answers of the first sort are clearly relevant to epistemological evaluation. In assessing whether you know p or are rational in believing it to the degree you do, I will naturally want to consider what reasons you have for your belief. In deliberating myself about whether to believe p, in seeking an answer to the question of whether p, I will naturally consider what reasons or grounds I have to suppose that p. But what I want to focus on here is how explanations of the broader sort bear on such questions as whether to believe p. From a third-person perspective we can ask, ‘In assessing the epistemic status of S’s belief that p, what is the relevance of causal information that lies outside of the realm of justifying reasons?’ From the first-person standpoint we can ask ‘In seeking to answer whether p, how should such causal information affect my deliberations?’ At first it might seem that such broader causal information could have little relevance if any. Like any belief my belief that p can be traced back to innumerable causes from far and wide.. (shrink)

It is common orthodoxy among internalists and externalists alike that knowledge is lost or defeated in situations involving misleading evidence of a suitable kind. But making sense of defeat has seemed to present a particular challenge for those who reject an internalist justification condition on knowledge. My main aim here is to argue that externalists ought to take seriously a view on which knowledge can be retained even in the face of strong seemingly defeating evidence. As an instructive example, I (...) first discuss whether a theory on which knowledge is belief that is safe from error has the resources for accommodating defeat. I argue that beliefs retained in defeat cases need not be unsafe or true in some accidental way. I then discuss externalist strategies for explaining why we have incorrect intuitions about defeat. The notion of an epistemically reasonable subject plays a central role in my theory. Reasonable subjects adopt general strategies that are good for acquiring true belief and knowledge across a wide range of normal cases, but stubbornly retaining belief in the face of new evidence does not reflect such policies. I argue that though the methods employed by subjects who fail to adjust their beliefs in defeat cases may be perfectly good, they are not good methods to adopt, as their adoption is accompanied by bad dispositions. What emerges is a view on which a subject can know despite being unreasonable, and despite failing to manifest dispositions to know across normal cases. Unreasonable subjects are genuinely criticisable, but like almost anything, knowledge can sometimes be achieved in the absence of a good general strategy. (shrink)

Single-premise epistemic closure is the principle that: if one is in an evidential position to know that P where P entails Q, then one is in an evidential position to know that Q. In this paper, I defend the viability of opposition to closure. A key task for such an opponent is to precisely formulate a restricted closure principle that remains true to the motivations for abandoning unrestricted closure but does not endorse particularly egregious instances of closure violation. I focus (...) on two brands of epistemic theory that naturally incorporate closure restrictions. The first type holds that the truth value of a knowledge ascription is relative to a relevant question. The second holds that the truth value of a knowledge ascription is relative to a relevant topic. For each approach, I offer a formalization of a leading theory from the literature and use this formalization to evaluate the theory’s adequacy in terms of a precise set of desiderata. I conclude that neither theory succeeds in meeting these desiderata, casting doubt on the viability of the underlying approaches. Finally, I offer a novel variant of the topic-sensitive approach that fares better. (shrink)

We need to understand the impossible. Francesco Berto and Mark Jago start by considering what the concepts of meaning, information, knowledge, belief, fiction, conditionality, and counterfactual supposition have in common. They are all concepts which divide the world up more finely than logic does. Logically equivalent sentences may carry different meanings and information and may differ in how they're believed. Fictions can be inconsistent yet meaningful. We can suppose impossible things without collapsing into total incoherence. Yet for the leading philosophical (...) theories of meaning, these phenomena are an unfathomable mystery. To understand these concepts, we need a metaphysical, logical, and conceptual grasp of situations that could not possibly exist: Impossible Worlds. This book discusses the metaphysics of impossible worlds and applies the concept to a range of central topics and open issues in logic, semantics, and philosophy. It considers problems in the logic of knowledge, the meaning of alternative logics, models of imagination and mental simulation, the theory of information, truth in fiction, the meaning of conditional statements, and reasoning about the impossible. In all these cases, impossible worlds have an essential role to play. (shrink)

There is a long-standing debate about whether poetry can make a substantive contribution to philosophy with compelling arguments to show that poetry and philosophy involve distinct modes of thought and aims, albeit with similar concerns. This paper argues that reading lyric poetry can play a substantive role in philosophy by helping the philosopher understand how to forge connections with the perspectives of others. The paper takes the view that poetry is not directly philosophical but can play an important role in (...) developing the philosopher's awareness of how perspective shapes beliefs and thought processes. Following Robert Nozick, David Lewis, and Helen Beebee, it argues for the need to broaden our conception of the aims of philosophy beyond aiming for conclusive proof, at the least where philosophical inquiry is focused on questions of value. It then shows how poetry cultivates an intellectual virtue essential to philosophy aimed at uncovering equilibria and collective understanding. (shrink)

I lay out the framework for my theory of sensory imagination in “Imagining as a guide to possibility.” Sensory imagining involves mental imagery , and crucially, in describing the content of imagining, I distinguish between qualitative content and assigned content. Qualitative content derives from the mental image itself; for visual imaginings, it is what is “pictured.” For example, visually imagine the Philadelphia Eagles defeating the Pittsburgh Steelers to win their first Super Bowl. You picture the greenness of the field and (...) the football’s brown oblong shape. Some of what you imagine isn’t explicitly pictured, however. That it is Sunday, that it is the Super Bowl: these facts are assigned. (shrink)

Whereas traditional nominalists accept the realist's challenge to solve a 'Problem of Universals', the Ostrich Nominalist responds that there is no such Problem to answer. I suggest that Ostrich Nominalist arguments expose a genuine flaw in the realist project. However, I argue, Ostrich Nominalism is ultimately defeated by a problem about the analysis of qualitative sameness and difference. Qualitative sameness and difference are adequately understood only as sameness or difference in some respect. The need to say what these respects of (...) sameness and difference are (if not universals) constitutes a genuine Problem of Universals; consequently—I claim—the Ostrich Nominalist is mistaken.

Any inquiry into the meaning and implications of the prolongation of the human lifespan requires an investigation of its metaphysical basis and its ethical outcomes. This chapter explains a series of metaphysical and ethical claims about lifespan extension. It highlights a number of arguments that are typically put forward against these claims, and shows the ways in which they are mistaken. Two such claims given in the chapter are: (1) aging and life stages are neither wholly constituted by biological givens, (...) nor wholly understandable in terms of biological parameters; instead, aging and life stages are, in crucial ways, socially constructed; and (2) death is bad, and other things being equal, a longer life is a better life.

Philosophical Papers 36.1 (2007): 151-161.

This article treats recent bioethical discussions of double effect reasoning (DER), offering a summary account of DER and construing it as rooted in a sensible view of what is central to someone's identity as a moral agent. It then treats objections raised in recent years by Judith Thomson, Alison McIntyre, and Frances Kamm against familiar ways of applying DER to certain controversies within medical ethics, especially, that over physician-assisted suicide. After detailing, interpreting, and attempting to rebut the challenges from these (...) philosophers, who are especially interesting because their criticisms of DER come from allies in DER's struggle against consequentialist reasoning, the essay engages DER's contribution to a recent dispute over treatment of patients in what is called ‘persistent vegetative state.' Near its end, the paper sketches several possible points of entry to DER and sources of justification for it. The essay concludes by indicating a connection between these paths and its opening idea of moral identity. (shrink)

I argue that its appearing to you that P does not provide justification for believing that P unless you have independent justification for the denial of skeptical alternatives – hypotheses incompatible with P but such that if they were true, it would still appear to you that P. Thus I challenge the popular view of ‘dogmatism,’ according to which for some contents P, you need only lack reason to suspect that skeptical alternatives are true, in order for an experience as (...) of P to justify belief that P. I pursue three lines of objection to dogmatism, having to do with probabilistic reasoning, considerations of future or hypothetically available justification, and epistemic circularity. I briefly sketch a fall-back position which avoids the problems raised. (shrink)

If our experiences are cognitively penetrable, they can be influenced by our antecedent expectations, beliefs, or other cognitive states. Theorists such as Churchland, Fodor, Macpherson, and Siegel have debated whether and how our cognitive states might influence our perceptual experiences, as well as how any such influences might affect the ability of our experiences to justify our beliefs about the external world. This article surveys views about the nature of cognitive penetration, the epistemological consequences of denying cognitive penetration, and the (...) epistemological consequences of affirming cognitive penetration.

Part of the Elements Philosophy of Religion series, this short book focuses on the spiritual dimensions of life’s meaning as they have been discussed in the recent English and mainly analytic philosophical literature. The overarching philosophical question that this literature has addressed is about the extent to which, and respects in which, spiritual realities such as God or a soul would confer meaning on our lives. There have been four broad answers to the question, namely: God or a soul is (...) necessary for meaning in our lives; they are not necessary for it; one or both would enhance the meaning in our lives; and they would detract from it. These views have been largely advanced in chronological order through the history of Western philosophy, with the view that life would be meaningless without God and a soul having been most prominent in the medieval period, the rejection of this claim having arisen in the modern era, and then sophisticated positions about enhancement or reduction having appeared in earnest only in the past 20 years. This book addresses all four positions, paying particular attention to the more recent views. Beyond familiarizing readers with these positions, it presents prima facie objections to them, points out gaps in research agendas, and suggests argumentative strategies that merit development.

I aim at dissolving Kripke's dogmatism paradox by arguing that, with respect to any particular proposition p which is known by a subject A, it is not irrational for A to ignore all evidence against p. Along the way, I offer a definition of 'A is dogmatic with respect to p', and make a distinction between an objective and a subjective sense of 'should' in the statement 'A should ignore all the evidence against p'. For the most part, I deal (...) with Kripke's original version of the paradox, wherein the subject wishes, above all else, to avoid losing her true belief or gaining a false one; in the final section I investigate the possibility of having a paradox for a subject who values knowledge above anything else.

Does G. E. Moore know that he has hands? Yes, says the dogmatist: Moore’s hands are right before his eyes. No, says the skeptic: for all Moore knows he could be a brain-in-a-vat. Yes and no, says the contrastivist: yes, Moore knows that he has hands rather than stumps; but no, Moore does not know that he has hands rather than vat-images of hands. The dogmatist and the skeptic suppose that knowledge is a binary, categorical relation: s knows that p. (...) The contrastivist says that knowledge is a ternary, contrastive relation: s knows that p rather than q. (shrink)

The default position in Western ethics is that survivor’s guilt is either irrational or not rational, i.e., that while survivor’s guilt might be understandable, it is not justified in the sense of there being good reason for a person to exhibit it. From a widely held perspective, for example, one ought to feel guilty only for having done wrong, and in a culpable way, which, by hypothesis, a mere survivor has not done. Typical is the following: ‘Strictly speaking, survivor guilt (...) is not rational guilt, for surviving the Holocaust, or surviving battle….is not typically because a person has deliberately let another take his place in harm’ (N Sherman, ‘Guilt in War’). However, I find in the African tradition resources that promise to entail and plausibly explain why it would be reasonable, and specifically morally desirable, for a person to feel survivor’s guilt. The core idea that I take from this tradition is that a person is virtuous insofar as she is communal in her actions and attitudes. In my contribution I develop the hypothesis that feeling guilty upon the dumb luck of survival can be apt as a virtuous form of one’s attitudes being positively bound up with others. (shrink)

This essay first analyzes the concept of survivor’s guilt, distinguishing various manifestations of it and considering whether any truly counts as a form of guilt. Then, it addresses arguments for thinking that survivor’s guilt is unreasonable to exhibit, after which it takes up arguments for thinking that it is reasonable. The aim is not to come to some firm conclusion about these conceptual and evaluative matters, but instead to acquaint the reader with the debates about them among contemporary English-speaking philosophers.

In this chapter, we argue that it’s possible to lose your faith in God by the actions of other people. In particular, we argue that spiritually violent religious trauma, where religious texts are used to shame a person into thinking themselves unworthy of God’s love, can cause a person to stop engaging in activities that sustain their faith in God, such as engaging in the worship of God. To do this, we provide an analysis of faith, worship, and love on (...) which to have faith in God is to have an attitude of worship to him; to have such an attitude of worship to God is to love him; and to love God is to desire union with him. We apply this analysis particularly to the case of LGBT Christians and their experience in the church today. (shrink)

I shall offer some very plausible assumptions for the measure of confirmation and show that they imply that E confirms H relative to background K to degree f/PK), where f is a strictly increasing function. An additional assumption about how measures of confirmation combine then makes f be proportional to a logarithm.

The Principle of Sufficient Reason must be justified dialectically: by showing the disastrous consequences of denying it. We formulate a version of the Principle that is restricted to basic natural facts, which entails the obtaining of at least one supernatural fact. Denying this principle results in extreme empirical skepticism. We consider six current theories of empirical knowledge, showing that on each account we cannot know that we have empirical knowledge unless we all have a priori knowledge of the PSR. We (...) consider objections based on Neo-Humeanism and the essentiality of origins, and we consider the possibility that we have empirical knowledge without knowing it. (shrink)
