We consider the dispute between causal decision theorists and evidential decision theorists over Newcomb-like problems. We introduce a framework relating causation and directed graphs developed by Spirtes et al. (1993) and evaluate several arguments in this context. We argue that much of the debate between the two camps is misplaced; the disputes turn on the distinction between conditioning on an event E as against conditioning on an event I which is an action to bring about E. We give the essential (...) machinery for calculating the effect of an intervention and consider recent work which extends the basic account given here to the case where causal Knowledge is incomplete.

Chris Meek. Strong-Completeness and Faithfulness in Belief Networks.

Whenever the use of non-experimental data for discovering causal relations or predicting the outcomes of experiments or interventions is contemplated, two difficulties are routinely faced. One is the problem of latent variables, or confounders: factors influencing two or more measured variables may not themselves have been measured or recorded. The other is the problem of sample selection bias: values of the variables or features under study may themselves influence whether a unit is included in the data sample.

It has been shown in Spirtes(1995) that X and Y are d-separated given Z in a directed graph associated with a recursive or non-recursive linear model without correlated errors if and only if the model entails that ρXY.Z = 0. This result cannot be directly applied to a linear model with correlated errors, however, because the standard graphical representation of a linear model with correlated errors is not a directed graph. The main result of this paper is to show how (...) to associate a directed graph with a linear model L with correlated errors, and then use d-separation in the associated directed graph to determine whether L entails that a particular partial correlation is zero.

This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.

Clark Glymour, Richard Scheines, Peter Spirtes, and Christopher Meek. Regression and Causation.

Clark Glymour, together with his students Peter Spirtes and Richard Scheines, did pioneering work on graphical causal models . One of the central advances provided by these models is the ability to simply represent the effects of interventions. In an elegant paper , Glymour and his student Christopher Meek applied these methods to problems in decision theory. One of the morals they drew was that causal decision theory should be understood in terms of interventions. I revisit their proposal, (...) and extend the analysis by showing how graphical causal models might be used to address decision problems that arise in “exotic” situations, such as those involving crystal balls or time travelers.

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.

This study examined people’s ability to predict and postdict their performance on an event-based prospective memory task. Using nonfocal cues, one group of participants predicted their success at finding animal words and a different group predicted their ability to find words with a particular syllable in it. The authors also administered a self-report questionnaire on everyday prospective and retrospective memory failures. Based on the different strategies adopted by the two groups and correlations among the dependent variables, the authors concluded that (...) people do have a basic awareness of their prospective memory abilities, but that this awareness is far from accurate. The importance of metamemory concerning one’s prospective memory is discussed in terms of how it influences the strategies that people might choose for actually completing their various everyday intentions.

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.

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)

Abstract: While recent scholarship often makes the claim that Plato’s theology in the Laws is based upon inferences from observable features about the world, this interpretation runs into difficulties when one considers (1) the continuing importance that the Socratic turn undertaken in the Phaedo has for speculation in the Laws about the order of the cosmos and (2) the actual observations that Plato makes about the sublunar and celestial realms in the Laws. In light of these difficulties, I develop an (...) interpretation of the theology of the Laws that seeks to show the priority of soul to matter by means of an articulation of the fundamental orientation to the world that is manifest in human beings seeking shared understanding through λόγος. This fundamental orientation is characterized by the recognition that νοῦς, not personal ambition, should guide human action and thought, and I argue that this recognition supplies at least partial support for the belief that νοῦς is in control of the cosmos. This interpretation helps makes sense of difficult passages in the Platonic corpus that ground cosmology on piety (Laws 10.898c6, Philebus 28e2, Timaeus 29a4). The relationship of this philosophical piety to the piety required by the laws of Magnesia is, however, problematic, and it could appear that Plato bridges this gap by a prudentialist account of why the laws of the city should be considered divine. I broach this problem in the final section of this paper by way of an examination of the relationship between the second sailing (δεύτερος πλοῦς) of the Phaedo and the δεύτερος πλοῦς of the Statesman and the Laws. I conclude with the observation that both the Phaedo and the Laws make use of an enchantment (ἐπῳδή) that goes beyond the bounds of what λόγος can establish. (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)

Several foundational documents of bioethics mention the special obligation researchers have to vulnerable research participants. However, the treatment of vulnerability offered by these documents often relies on enumeration of vulnerable groups rather than an analysis of the features that make such groups vulnerable. Recent attempts in the scholarly literature to lend philosophical weight to the concept of vulnerability are offered by Luna and Hurst. Luna suggests that vulnerability is irreducibly contextual and that Institutional Review Boards (Research Ethics Committees) can only (...) identify vulnerable participants by carefully examining the details of the proposed research. Hurst, in contrast, defines the vulnerable as those especially at risk of incurring the wrongs to which all research ethics participants are exposed. We offer a more substantive conception of vulnerability than Luna but one that gives rise to a different rubric of responsibilities from Hurst's. While we understand vulnerability to be an ontological condition of human existence, in the context of research ethics, we take the vulnerable to be research subjects who are especially prone to harm or exploitation. Our analysis rests on developing a typology of sources of vulnerability and showing how distinct sources generate distinct obligations on the part of the researcher. Our account emphasizes that the researcher's first obligation is not to make the research participant even more vulnerable than they already are. To illustrate our framework, we consider two cases: that of a vulnerable population involved in international research and that of a domestic population of people with diminished capacity. (shrink)

On the face of it, the protracted public controversy over abortion in the United States and elsewhere might seem to rest on intractable normative questions inaccessible to economic analysis. But an influential early essay in the now sizable philosophical literature on the subject suggests otherwise. Judith Jarvis Thomson disarmingly inclined toward the view that “the fetus has already become a human person well before birth”,. presumably with all the rights pertaining thereto. She denied, however, that such rights necessarily include use (...) of the mother's womb until birth. To illustrate her point, she compared the mother's situation to that, for example, of an unwilling Good Samaritan with a uniquely suited blood type, who is forced to share a kidney for 9 months with a famous, ailing violinist who needed its use for that duration to recover. Even if the life of a human being was at stake, the assertion of rights for the violinist or the fetus, she argued, would be too degrading for either the Good Samaritan's or the mother's status as a person, where large unwanted sacrifices would be required. Reduced to its economic essentials, the argument is that the mother has property rights to her own body, including the right to expel a “trespasser”. who would die as a consequence. Thus, the antiabortion position is neatly undercut by granting its major premise while denying its conclusion. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Stanley Cavell: Philosophy’s Recounting of the OrdinaryRoblin MeeksStanley Cavell: Philosophy’s Recounting of the Ordinary, by Stephen Mulhall; xxv & 351 pp. New York: Oxford University Press, 1994, $52.00.Despite what his book’s title might suggest, Stephen Mulhall’s thorough explication of Stanley Cavell’s philosophy is anything but ordinary. At the outset Mulhall makes it clear that he intends to address Cavell’s exceptional formidability, and sets himself “not to attempt to (...) do what can and must only be done by Cavell’s own prose, but to clear the space that is required for it to do so” (p. vii). He grapples with those peculiar factors that fortify Cavell’s work against many readers: a viscous style and the manifold directions in which that style has stretched. An extensive exegesis, Mulhall believes, will prepare the ground for thoughtful critiques long overdue.In order to disarm Cavell’s “unfashionable tone” (p. viii), Mulhall opens with a discussion of Cavell’s earlier and more traditional work in aesthetics. He carefully attends to the ways in which Cavell appropriated and practiced ordinary language philosophy as established by Wittgenstein and Austin, and in so doing he displays Cavell’s struggle with this methodological inheritance. Conceiving it as the “paradigmatically modern philosophy” (p. 73), Cavell believes that ordinary language creates a tension between philosophy’s present and its past inflections—an urgency he finds ubiquitous in modern Western culture, echoed in contemporary painting and music. For Cavell, philosophy is invariably both subject and object.The second part of the book informs and extends the first, addressing Cavell’s elemental motivation—skepticism. Mulhall shows that Cavell “sees the practices of ordinary language philosophy as everywhere set in opposition to [End Page 407] the skeptical impulse” (p. 186). In reply to each “specific outbreak of what seems to be a fundamental human desire to repudiate that which aligns speakers with one another and with the world they inhabit” (p. 186), Cavell argues that investigations into the criteria governing what we say when—this is the sense in which he “recounts the ordinary”—can reaffirm the alignments between speakers and their world.Mulhall devotes most of his remaining pages to subjects in which Cavell observes the meeting of ordinary language philosophy and the skeptical impulse: film, literary theory, psychoanalysis, and the writings of Shakespeare, Emerson, and Thoreau—subjects traditionally located outside the philosophical pale of settlement. Mulhall demonstrates how these things have in turn shaped Cavell’s own method. Where Wittgenstein, for example, adopted a dense but laconic approach in his investigations, Cavell has come to exercise a species of Emersonian perfectionism. His abundant prose is intended to revise and to expand upon itself, offering itself up for criticism.Mulhall himself, however, does not fully accept this invitation. Since he states in his introduction that he is interested primarily in opening up Cavell’s philosophy for genuine critical response, and since he presents the strongest possible case on its behalf, he is in an ideal position—indeed, no one is better positioned—to offer an exhaustive critique. And yet the criticism he eventually levels (Cavell’s reliance upon religious metaphor is undercut by a chronic distaste for Christianity) fails to persuade; it is inadequately developed. Mulhall wants to maintain the exegete’s distance even when Cavell’s writing beckons him into the more intimate role of critic.Mulhall is right that Cavell’s philosophical aim is “to create a set of texts, to establish and maintain a texture of prose, that can earn the title of philosophy from its readers” (p. xiv). But he insufficiently explores the degree to which the skeptical impulse fundamentally infects this overarching ambition with doubt. And so he under-appreciates Cavell’s vexation. For if ordinary language philosophy—in working through the ineluctable tension between modernity and history—cannot produce work capable of being called philosophy or itself fails to find an audience, what can? Such questions ultimately lead back to Cavell’s own prose, and it is to Mulhall’s credit that he has cleared the space for such a return.Roblin MeeksCity University of New YorkCopyright © 1995 The Johns Hopkins University Press...

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.

The psychological writing of Jung and the post-Jungians is all too often ignored as anachronistic, archaic and mystic. In Jung and the Postmodern, Christopher Hauke challenges this, arguing that Jungian psychology is more relevant now than ever before - not only can it be a response to modernity, but it can offer a critique of modernity and Enlightenment values which brings it in line with the postmodern critique of contemporary culture. After introducing Jungians to postmodern themes in Jameson, Baudrillard, (...) Jencks and Foucault, the author introduces postmodernists to Jung's cultural critique and post-Jungian discussions of representation, individuation, consciousness, and the alternatives to Enlightenment rationality. He also takes a totally fresh approach to topics such as hysteria and the body, Jung and Nietzsche, architecture and affect, Princess Diana and the 'death' of the subject, postmodern science and synchronicity, and to psychosis and alternative 'rationalities'. Jung and the Postmodern is vital reading for everyone interested in contemporary culture, not only Jungians and other psychotherapists who want to explore the social relevance of their discipline, but anyone who shares a assionate concern for where we are heading in postmodern times.

This handbook article gives a critical overview of recent discussions of epistemic authority. It favors an account that brings into balance the dictates of rational deference with the ideals of intellectual self-governance. A plausible starting point is the conjecture that neither should rational deference to authorities collapse into total epistemic submission, nor the ideal of mature intellectual self-governance be conflated with (illusions of) epistemic autarky.

What is involved in the consciousness of a conscious, "occurrent" propositional attitude, such as a thought, a sudden conjecture or a conscious decision? And what is the relation of such consciousness to attention? I hope the intrinsic interest of these questions provides sufficient motivation to allow me to start by addressing them. We will not have a full understanding either of consciousness in general, nor of attention in general, until we have answers to these questions. I think there are constitutive (...) features of these states which can be identified by broadly philosophical investigation, and in the early part of this paper I will try to do some of that identification. -/- Beyond the intrinsic interest of the topic, the nature of such conscious attitudes is highly pertinent to a philosophical account of psychological self-knowledge. So I will also say something about the significance of the constitutive features of these conscious attitudes for a philosophical account of how it can be that a thinker has a distinctive kind of knowledge of some of his mental states. The general challenge in this area is to find anything intermediate between the unexceptionable but uninformative, on the one hand, and the absolutely unbelievable on the other. (shrink)

Suppose you ask yourself whether your father's record collection includes a certain recording of The Trout and venture to find out. At that time, you embark on an inquiry into whether your father owns the relevant recording. Your inquiry is a project with a specific goal: finding out whether your father owns the recording. This fact about your inquiry generalizes: inquiry is a goal-directed enterprise. A specific inquiry can be individuated by the question it aims to answer and by who (...) aims to answer the question. Your inquiry into whether your father owns the recording differs from your inquiry into how many records your father owns because different questions are being asked. Your inquiry into whether your father owns the recording differs from my inquiry into whether he does because different people are inquiring. The goal of inquiry into a given question by an agent, α, can be characterized, neutrally, as α's having the answer to that question. I will here focus only on inquiries into whether questions and characterize the goal of inquiry into whether φ by α as α's having the answer to the question whether φ. (shrink)

In apparent motion experiments, participants are presented with what is in fact a succession of two brief stationary stimuli at two different locations, but they report an impression of movement. Philosophers have recently debated whether apparent motion provides evidence in favour of a particular account of the nature of temporal experience. I argue that the existing discussion in this area is premised on a mistaken view of the phenomenology of apparent motion and, as a result, the space of possible philosophical (...) positions has not yet been fully explored. In particular, I argue that the existence of apparent motion is compatible with an account of the nature of temporal experience that involves a version of direct realism. In doing so, I also argue against two other claims often made about apparent motion, viz. that apparent motion is the psychological phenomenon that underlies motion experience in the cinema, and that apparent motion is subjectively indistinguishable from real motion.

This paper argues that we should replace the common classification of theories of welfare into the categories of hedonism, desire theories, and objective list theories. The tripartite classification is objectionable because it is unduly narrow and it is confusing: it excludes theories of welfare that are worthy of discussion, and it obscures important distinctions. In its place, the paper proposes two independent classifications corresponding to a distinction emphasised by Roger Crisp: a four-category classification of enumerative theories (about which items constitute (...) welfare), and a four-category classification of explanatory theories (about why these items constitute welfare).

This article presents an overview of the basic philosophical motivations for, and some recent work in, modal set theory.

Ectogestation involves the gestation of a fetus in an ex utero environment. The possibility of this technology raises a significant question for the abortion debate: Does a woman’s right to end her pregnancy entail that she has a right to the death of the fetus when ectogestation is possible? Some have argued that it does not Mathison & Davis. Others claim that, while a woman alone does not possess an individual right to the death of the fetus, the genetic parents (...) have a collective right to its death Räsänen. In this paper, I argue that the possibility of ectogestation will radically transform the problem of abortion. The argument that I defend purports to show that, even if it is not a person, there is no right to the death of a fetus that could be safely removed from a human womb and gestated in an artificial womb, because there are competent people who are willing to care for and raise the fetus as it grows into a person. Thus, given the possibility of ectogestation, the moral status of the fetus plays no substantial role in determining whether there is a right to its death. (shrink)

Representation theorems are often taken to provide the foundations for decision theory. First, they are taken to characterize degrees of belief and utilities. Second, they are taken to justify two fundamental rules of rationality: that we should have probabilistic degrees of belief and that we should act as expected utility maximizers. We argue that representation theorems cannot serve either of these foundational purposes, and that recent attempts to defend the foundational importance of representation theorems are unsuccessful. As a result, we (...) should reject these claims, and lay the foundations of decision theory on firmer ground. (shrink)
