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.

This article explores the evolution of Principles of Biomedical Ethics by Tom Beauchamp and James Childress over its seven editions. Many changes have occurred in the text over the last thirty-five years, including the expansion of the section on virtue ethics, the modification of the authors’ position on physician-assisted suicide, and the addition of many other ethical theories to the original two found in the first editions. The basis for these changes and others seems to be their development of the (...) theme of the “common morality.” The author suggests that Beauchamp and Childress develop the connection between their common morality and metaphysics, as it would serve to strengthen their theory and make it less susceptible to changes in society’s opinions and traditions.

This article examines the approaches that historians, beginning in the mid 20th century and into the early 21st century, used to write about the Winnipeg General Strike of 1919. It focuses on five major works: The Winnipeg General Strike by D.C. Masters; Confrontation at Winnipeg by David J. Bercuson; The Workers' Revolt in Canada, 1917-1925 edited by Craig Heron; and When the State Trembled: How A.J. Andrews and the Citizens' Committee Broke the Winnipeg General Strike by Tom Mitchell and (...) Reinhold Kramer. It identifies where the monographs depart from one another in interpretation; as well as where they remain the same. Given the layers of complexity, the interpretation of the event becomes especially salient in the 21st century as its 100th anniversary steadfastly approaches and the question of how should it be publicly presented in 2019 requires an answer soon.

Apology: My knowledge of of machine learning is no more recent than Tom Mitchell's book. Its chapters describe, except for inductive logic programming, programs aimed at classifying appearances.

Many individuals have miserable work lives, in which they must toil away at mind-numbing yet exhausting tasks for hours on end, being ordered about by their superiors, perhaps with few guarantees that this source of income will persist for very long. However, this is only half of the story: what is centrally important is that many of those who endure these conditions are denied a fair wage in return for the burdens that they bear. In this article, I reflect on (...) the significance of this fact in order to argue for the evaporation thesis. This thesis holds that individuals’ claims to particular employment-related protections from their government disappear as their earnings increase. In the course of defending this position, I explore the moral difference an employee's wage offer makes to the work conditions that we can expect her to accept, including why there are limits to the role that cash can play here.

In this essay we critically evaluate the progress that has been made in solving the problem of meaning in artificial intelligence (AI) and robotics. We remain skeptical about solutions based on deep neural networks and cognitive robotics, which in our opinion do not fundamentally address the problem. We agree with the enactive approach to cognitive science that things appear as intrinsically meaningful for living beings because of their precarious existence as adaptive autopoietic individuals. But this approach inherits the problem of (...) failing to account for how meaning as such could make a difference for an agent’s behavior. In a nutshell, if life and mind are identified with physically deterministic phenomena, then there is no conceptual room for meaning to play a role in its own right. We argue that this impotence of meaning can be addressed by revising the concept of nature such that the macroscopic scale of the living can be characterized by physical indeterminacy. We consider the implications of this revision of the mind-body relationship for synthetic approaches. (shrink)

Regan provides the theoretical framework that grounds a responsible pro-animal rights perspective, and ultimately explores how asking moral questions about other animals can lead to a better understanding of ourselves.

Credentialism refers to the practice of hiring or promoting applicants on the basis of their educational qualifications. In this paper, we argue that this can amount to wrongful discrimination against the less qualified. A standard way to defend credentialism appeals to the fact that it minimizes the costs of production. We argue that this argument has unacceptable implications in some cases involving disability- and gender-based discrimination. We claim that, once we appropriately revise this argument, credentialism is revealed to be similarly (...) wrongfully discriminatory. We then consider two objections and draw some preliminary lessons for policymaking. (shrink)

This study examines a moderated/mediated model of ethical leadership on follower job satisfaction and affective organizational commitment. We proposed that managers have the potential to be agents of virtue or vice within organizations. Specifically, through ethical leadership behavior we argued that managers can virtuously influence perceptions of ethical climate, which in turn will positively impact organizational members’ flourishing as measured by job satisfaction and affective commitment to the organization. We also hypothesized that perceptions of interactional justice would moderate the ethical (...) leadership-to-climate relationship. Our results indicate that ethical leadership has both a direct and indirect influence on follower job satisfaction and affective commitment. The indirect effect of ethical leadership involves shaping perceptions of ethical climate, which in turn, engender greater job satisfaction and affective organizational commitment. Furthermore, when interactional justice is perceived to be high, this strengthens the ethical leadership-to-climate relationship. (shrink)

Our successful engagement with the world is plausibly underwritten by our sensitivity to affordances in our immediate environment. The considerable literature on affordances focuses almost exclusively on affordances for bodily actions such as gripping, walking or eating. I propose that we are also sensitive to affordances for mental actions such as attending, imagining and counting. My case for this ‘Mental Affordance Hypothesis’ is motivated by a series of examples in which our sensitivity to mental affordances mirrors our sensitivity to bodily (...) affordances. Specifically, subjects perceive opportunities to perform a mental action and their doing so leads, under the right conditions, to the automatic preparation of that action. I conclude by sketching a mental affordance research program that would reinforce my case for the Mental Affordance Hypothesis and establish its ramifications for a number of debates across philosophy and psychology.

This book defends Aestheticism- the claim that everything is aesthetically valuable and that a life lived in pursuit of aesthetic value can be a particularly good one. Furthermore, in distilling aesthetic qualities, artists have a special role to play in teaching us to recognize values; a critical component of virtue. I ground my account upon an analysis of aesthetic value as ‘objectified final value’, which is underwritten by an original psychological claim that all aesthetic values are distal versions of practical (...) values. This is followed by systematic accounts of beauty, sublimity, comedy, drama, and tragedy, as well as appendix entries on the cute, the cool, the kitsch, the uncanny, the horrific, the erotic, and the furious.

This anthology represents all of the most important points of view on the most pressing topics in bioethics. Containing current essays and actual medical and legal cases written by outstanding scholars from around the globe, this book provides readers with diverse range of standpoints, including those of medical researchers and practitioners, legal exerts, and philosophers.

Tyler conducted a longitudinal study of 1,575 Chicago inhabitants to determine why people obey the law. His findings show that the law is obeyed primarily because people believe in respecting legitimate authority, not because they fear punishment. The author concludes that lawmakers and law enforcers would do much better to make legal systems worthy of respect than to try to instill fear of punishment.

This paper has two main aims. First, it examines the relation of Russian and Chinese Marxism against its Hegelian background. Secondly, it comments on recent Western research on Marxism in tracing the origins of Engels’s anti-Hegelianism to materialist reactions to modern idealist philosophy. I maintain that Engels is a Schellingian, that Marx is a Hegelian, and that Marx’s form of Hegelianism cannot be realized in practice. I consider different kinds of Marxism as efforts to realize Marx’s theories and argue that, (...) since Marx’s theory cannot be realized, in the final analysis his view is no more than a dream.

In this paper we focus on a kind of perceptual states that we call perceptual motivations, that is, perceptual experiences that plausibly motivate us to act, such as itching, perceptual salience and pain. Itching seems to motivate you to scratch, perceiving a stimulus as salient seems to motivate you to attend to it and feeling a pain in your hand seems to motivate actions such as withdrawing from the painful stimulus. Five main accounts of perceptual motivation are available: Descriptive, Conative, (...) Imperativist, Reflexive and Dual Content views. Some of these have been developed in detail and others are natural extensions of existing views. However, we argue that none provides a satisfactory account of the target perceptual states. Driven by the failings of each account, we identify three conditions that any satisfactory theory of perceptual motivation must meet: Direct Motivational Force, Non-Obligatory Force and Intention-Independent Influence. Then we offer an account that attempts to fulfil these conditions: the Affordance Model. This model of perceptual motivation is premised on the claim that each of the target states involves the perception of a specific affordance for action and the triggering of Automatic Motor Initiations. We suggest that AMIs can explain the motivational force of these perceptual states. (shrink)

The fear of death resists philosophical attempts at reconciliation. Building on theories of emotion, I argue that we can understand our fear as triggered by a de se mode of thinking about death which comes into conflict with our will to live. The discursive mode of philosophy may help us to avoid the de se mode of thinking about death, but it does not satisfactorily address the problem. I focus instead on the voluntary diminishment of one’s will to live. I (...) argue that we can encourage a natural tendency for the will to live to decline as we approach death. I then consider two objections: Is not the will to live too fundamental for us to control? And even if we can control it, would not a declining will to live result in a general despair that it is better to resist? I argue that both of these objections can be overcome. (shrink)

'By identifying the extent to which Aristotle's thinking about ethics was shaped by notions drawn from the crafts Angier has thrown new light on a surprising number of topics and has deepened our understanding of tensions within Aristotle's thought. It is by now a rare achievement to have said something new, true and important about Aristotle.' -- Alasdair MacIntyre, Emeritus Professor of Philosophy, University of Notre Dame, USA.

This new edition of Hume's Enquiry concerning the Principles of Morals, published in the Oxford Philosophical Texts series, has been designed especially for the student reader. The text is preceded by a substantial introduction explaining the historical and intellectual background to the work and its relationship to the rest of Hume's philosophy. The volume also includes detailed explanatory notes on the text, a glossary of terms, and a section of supplementary readings.

Tom Eyers contrasts the different “movements” of the novel and the lyric poem: while moments of stasis in the novel are swept up in its narrative trajectory, atemporal moments in poetry can be juxtaposed against other kinds of temporality — for Eyers’s purposes, most importantly the temporalities of politics and history. The Theory of the Novelbecomes a theory of the lyric, undoing the persistent belief that history can only be made to appear in narrative.

On the basis of psychological research, a group of philosophers known as 'situationists' argue that the evidence belies the existence of broad and stable (or 'global') character traits. They argue that this condemns as psychologically unrealistic those traditions in moral theory in which global virtues are upheld as ideals. After a survey of the debate to date, this article argues that the thesis of situationism is ill-supported by the available evidence. Situationists overlook the explanatory potential of a large class of (...) global character traits, namely, vices that do not involve other-directed malevolence, such as laziness, cowardice, and selfishness. A detailed discussion of the relevant empirical studies bearing on moral psychology shows that the behavioral patterns observed in these studies are consistent with the widespread possession of such non-malicious vices. This means, contrary to the situationist thesis, that the empirical record is fully compatible with the common existence of global character traits. (shrink)

Abstract: I argue that practically all vague language is context-sensitive in a covert and unfamiliar way. I first outline a novel puzzle concerning the interaction of conditionals and vagueness. I then argue that the best way of resolving the puzzle is through positing context-sensitive penumbral connections between sundry parts of language. I argue that these penumbral connections shift through a distinct form of Lewisian accommodation. The upshot is that meaning is a far shiftier thing than has typically been thought.

"The well-known moral and political doctrines of Leviathan have tended to overshadow Hobbes's speculations in other fields. In this book doctrines familiar from the treatises on 'Policy', as well as less familiar empirical and metaphysical theories, are given balanced consideration against the background of his philosophy of science."--Bookjacket.

In this chapter I analyse group flow: a state in which performers report intense interpersonal absorption with the music and each other. I compare group flow to individual flow, and argue that the same essential structure can be discerned. I argue that group flow does not justify an anti-representationalist enactivist interpretation. However, I claim that the cognitive task in which the music is produced is irreducibly collective.

Metaphysics-first approaches dominate the current literature in the epistemology of modality. According to metaphysics-firsters, metaphysical theses have an important role in the justification of modal epistemologies. For example, the thesis that essentialist truths constitute the metaphysical grounds of modal truths is meant to have an important role in the justification of essentialist modal epistemologies. In this article, we argue against this approach. We first pick up some of the groundwork on behalf of the metaphysics-firsters and explicitly spell out potential arguments (...) for their view. However, despite some initial plausibility, these arguments are ultimately found wanting. We conclude that the metaphysics-first approach lacks motivation and puts far too stringent demands upon modal epistemologists. (shrink)

Theory theory and simulation theory share the assumption that mental states are unobservable, such that mental state attribution requires an extra psychological step beyond perception. Phenomenologists deny this, contending that we can directly perceive people's mental states. Here I evaluate objections to theory theory and simulation theory as accounts of everyday social perception offered by Dan Zahavi and Shaun Gallagher. I agree that their phenomenological claims have bite at the personal level, distinguishing direct social perception from conscious theorizing and simulation. (...) Their appeals to phenomenology and other arguments do not, however, rule out theory theory or simulation theory as accounts of the sub-personal processes underlying social perception. While I here remain uncommitted about the plausibility of sub-personal theorizing and simulation, I argue that phenomenologists must do more in order to reject these accounts. (shrink)

We take rights to be fundamental to everyday life. Rights are also controversial and hotly debated both in theory and practice. Where do rights come from? Are they invented or discovered? What sort of rights are there and who is entitled to them? In this comprehensive introduction, Tom Campbell introduces and critically examines the key philosophical debates about rights. The first part of the book covers historical and contemporary theories of rights, including the origin and variety of rights and standard (...) justifications of them. He considers challenges to rights from philosophers such as Bentham, Burke and Marx. He also examines different theories of rights, such as natural law, social contract, utilitarian and communitarian theories of rights and the philosophers and political theorists associated with them, such as John Stuart Mill, John Rawls, Robert Nozick and Michael Sandel. The second part of the book explores the role of rights-promoting institutions and critically assesses legal rights and international human rights, including the United Nations. The final part of the book examines how philosophies of rights can be applied to freedom of speech, issues of social welfare and the question of self-determination for certain groups or peoples. _Rights: A Critical Introduction_ is essential reading for anyone new to the subject of rights and any student of political philosophy, politics and law.

According to the virtual self theory, selves are merely virtual entities. On this view, our self-representations do not refer to any concrete object and the self is a merely intentional entity. This contemporary version of the ‘no-self’ theory is driven by a number of psychological and philosophical considerations indicating that our representations of the self are pervasively inaccurate. I present two problems for VST. First, the case for VST fails to rule out a more moderate position according to which the (...) self exists but is systematically misrepresented by us. This position regards the self as a real entity that has illusory appearances, rather than as a hallucinated entity that has a merely intentional existence. Second, I suggest that this ‘illusion model’ of self-misrepresentation is preferable to VST. Advocates of VST must acknowledge the existence of an entity—typically the brain—that is the bearer of our misrepresentations of the self. I argue that, other things being equal, we should regard the bearer of our self-representations as the self, even if that entity diverges dramatically from the way we represent the self to be. So by acknowledging the existence of a bearer of self-representations, advocates of VST are in a poor position to deny the existence of the self. I conclude that VST not only fails to rule out the illusion model, but that we have prima facie reason to prefer the illusion model to VST. (shrink)

In Section 1, I outline the history of natural law theory, covering Plato, Aristotle, the Stoics and Aquinas. In Section 2, I explore two alternative traditions of natural law, and explain why these constitute rivals to the Aristotelian tradition. In Section 3, I go on to elaborate a via negativa along which natural law norms can be discovered. On this basis, I unpack what I call three 'experiments in being', each of which illustrates the cogency of this method. In Section (...) 4, I investigate and rebut two seminal challenges to natural law methodology, namely, the fact/value distinction in metaethics and Darwinian evolutionary biology. In Section 5, I then outline and criticise the 'new' natural law theory, which is an attempt to revise natural law thought in light of the two challenges above. I conclude, in Section 6, with a summary and some reflections on the prospects for natural law theory. (shrink)

Some of the early‐modern changes in the social framing of science, while often believed to be essential, are shown to be contingent. They contribute to the flawed public narrative around science today, and especially to the misconceptions around science and religion. Four are examined in detail, each of which contributes to the demise of the contemplative stance that science both requires and offers. They are: (1) a turn from an immersed subject to the pretense of a pure objectivity, (2) a (...) turn from imagination as a legitimate pathway to knowledge, (3) a turn from shared and participative science to a restricted professionalism, and (4) an overprosaic reading of the metaphor of the “Book of Nature.” All four, but especially the imperative to consider reading nature as poetry, and a deeper examination of the entanglements between poetry and theoretical science, draw unavoidably on theological ideas, and contribute to a developing “theology of science.”.

about Hume: David Hume is one of the greatest of philosophers. Today he probably ranks highest of all British philosophers in terms of influence and philosophical standing. His philosophical work ranges across morals, the mind, metaphysics, epistemology, and aesthetics; he had broad interests not only in philosophy as it is now conceived but in history, politics, economics, religion, and the arts. He was a master of English prose. about the Clarendon Hume Edition: The Clarendon Hume will include all of his (...) works except his History of England and minor historical writings; it will be the only thorough critical edition, and will provide a far more extensive scholarly treatment than any previous editions. This edition offers authoritative annotation, bibliographical information, and indexes, and draws upon the major advances in textual scholarship that have been made since the publication of earlier editions--advances both in the understanding of editorial principle and practice and in knowledge of the history of Hume's own texts. General Editors: Professors T. L. Beauchamp, D. F. Norton, M. A. Stewart. The Edition will comprise: Vols. 1 and 2: A Treatise of Human Nature, edited by D. F. Norton Vol. 3: An Enquiry concerning Human Understanding, edited by T. L. Beauchamp Vol. 4: An Enquiry concerning the Principles of Morals, edited by T. L.

Researchers in the enactivist tradition have recently argued that social interaction can constitute social cognition, rather than simply serve as the context for social cognition. They contend that a focus on social interaction corrects the overemphasis on mechanisms inside the individual in the explanation of social cognition. I critically assess enactivism’s claims about the explanatory role of social interaction in social cognition. After sketching the enactivist approach to cognition in general and social cognition in particular, I identify problems with an (...) enactivist taxonomy of roles for social interaction in the explanation of social cognition (contextual, enabling, and constitutive). In particular, I show that this enactivist taxonomy does not clearly distinguish between enabling conditions and constitutive elements, which would make them in danger of committing the coupling-constitution fallacy found in some attempts to extend cognition. I explore resources enactivism has to more clearly demarcate constitutive parts of a cognitive system, but identify problems in applying them to some of the main cases of social cognition enactivists characterize as being constituted by social interaction. I offer the mechanistic approach to explanation as an alternative that captures much of what enactivists want to say about the relations between social and individual levels, but views social interactions from the perspective of embedded cognition rather than as being constitutive of social cognition.
