In this book, James Gordon Finlayson examines the Habermas-Rawls debate in context and considers its wider implications. He traces their dispute from its inception in their earliest works to the 1995 exchange and its aftermath, as well as its legacy in contemporary debates. Finlayson discusses Rawls’s Political Liberalism and Habermas’s Between Facts and Norms, considering them as the essential background to the dispute and using them to lay out their different conceptions of justice, politics, democratic legitimacy, individual rights, and (...) the normative authority of law. He gives a detailed analysis and assessment of their contributions, assessing the strengths and weaknesses of their different approaches to political theory, conceptions of democracy, and accounts of religion and public reason, and he reflects on the ongoing significance of the debate. The Habermas-Rawls Debate is an authoritative account of the crucial intersection of two major political theorists and an explication of why their dispute continues to matter. (shrink)

Throughout his career, Deleuze developed a series of original philosophies of time and applied them successfully to many different fields. Now James Williams presents Deleuze's philosophy of time as the central concept that connects his philosophy as a whole. Through this conceptual approach, the book covers all the main periods of Deleuze's philosophy: the early studies of Hume, Nietzsche, Kant, Bergson and Spinoza, the two great philosophical works, Difference and Repetition and Logic of Sense, the Capitalism and Schizophrenia works (...) with Guattari, and the late influential studies of literature, film and painting.The result is an important reading of Deleuze and the first full interpretation of his philosophy of time.

This is the first critical study of The Logic of Sense, Gilles Deleuze's most important work on language and ethics, as well as the main source of his vital philosophy of the event.James Williams explains the originality of Deleuze's work with careful definitions of all his innovative terms and a detailed description of the complex structure he constructs. This reading makes connections to his ground-breaking work on literature, to his critical but also progressive relation to the sciences, and to (...) his controversial denial of the priority of standard logics, human values and 'meaning' in thinking.This book will open new debates and develop current ones around Deleuze's work in philosophy, politics, literature, linguistics, cultural studies and sociology.

This is the first volume in which an account of personal autonomy is developed that both captures the contours of this concept as it is used in social philosophy and bioethics, and is theoretically grounded in, and a part of, contemporary autonomy theory. James Stacey Taylor’s account is unique as it is explicitly a political one, recognizing that the attribution of autonomy to agents is dependent in part on their relationships with others and not merely upon their own mental (...) states. The volume is distinctive in its examples, which touch on the ethics of using inducements to encourage persons to participate in medical research, the ethical issues associated with the use of antibiotics, and the ethical basis for both patient confidentiality and informed consent.

Philosophy and Phenomenological Research, EarlyView.

Despite their popularity, dual process accounts of human reasoning and decision-making have come under intense scrutiny in recent years. Cognitive scientists and philosophers alike have come to question the theoretical foundations of the ‘standard view’ of dual process theory and have challenged the validity and relevance of evidence in support of it. Moreover, attempts to modify and refine dual process theory in light of these challenges have generated additional concerns about its applicability and refutability as a scientific theory. With these (...) concerns in mind, this paper provides a critical review of dual process theory in economics, focusing on its role as a psychological framework for decision modeling in behavioral economics and neuroeconomics. I argue that the influx of criticisms against dual process theory challenge the descriptive accuracy of dualistic decision models in economics. In fact, the case can be made that the popularity of dual process theory in economics has less to do with the empirical success of dualistic decision models, and more to do with the convenience that the dual process narrative provides economists looking to explain-away decision anomalies. This leaves behavioral economists and neuroeconomists with something of a dilemma: either they stick to their purported ambitions to give a realistic description of human decision-making and give up the narrative, or they revise and restate their scientific ambitions.

James P. Sterba offers something that philosophers have long sought: an argument showing that morality is rationally required. Furthermore he argues that morality requires substantial equality. Even libertarian perspectives, which would seem to require minimal enforcement of morality, are shown to lead to a requirement of equality.

The idea behind this book is that developing a conception of the physical world and a conception of mind is impossible without the exercise of agency, meaning "the power to alter at will one's perceptual inputs". The thesis is derived from a philosophical account of the role of agency in knowledge - the first time this has been attempted in the context of developmental psychology. The book is divided into three parts. In Part One, Russell argues that purely "representational" theories (...) of mind and of mental development have been overvalued, thereby clearing the ground for the book's central thesis. In Part Two, he proposes that, because objective experience depends upon the experience of agency, the development of the "object concept" in human infants is grounded in the development of executive-attentional capacities. In Part Three, an analysis of the links between agency and self-awareness generates an original theory of the nature of certain stage-like transitions in mental functioning and of the relationship between executive and mentalising deficits in autism. The book will be of particular interest to students and researchers in cognitive-developmental psychology, to philosophers of mind, and to anybody with an interest in cognitive science. (shrink)

Adam Smith wrote two books, one about economics and the other about morality. How do these books go together? How do markets and morality mix? James Otteson provides a comprehensive examination and interpretation of Smith's moral theory and demonstrates how his conception of morality applies to his understanding of markets, language and other social institutions. Considering Smith's notions of natural sympathy, the impartial spectator, human nature and human conscience, the author addresses whether Smith thinks that moral judgments enjoy a (...) transcendent sanction.

Abstract:Disturbing cases continue to be published of patients declared brain dead who later were found to have a few intact brain functions. We address the reasons for the mismatch between the whole-brain criterion and brain death tests, and suggest solutions. Many of the cases result from diagnostic errors in brain death determination. Others probably result from a tiny amount of residual blood flow to the brain despite intracranial circulatory arrest. Strategies to lessen the mismatch include improving brain death determination training (...) for physicians, mandating a test showing complete intracranial circulatory arrest, or revising the whole-brain criterion.

Francis Bacon, the English philosopher, statesman and jurist, is best known for developing the empiricist method which forms the basis of modern science. Bacon's writings concentrated on philosophy and judicial reform. His most significant work is the Instauratio Magna comprising two parts - The Advancement of Learning and the Novum Organum. The first part is noteworthy as the first major philosophical work published in English. James Spedding and his co-editors arranged this fourteen-volume edition, published in London between 1857 and (...) 1874, not in chronological order but by subject matter, so that different volumes would appeal to different audiences. The material is divided into three parts: philosophy and general literature; legal works; and letters, speeches and tracts relating to politics. Volume 1, published 1857, contains the biography by Bacon's secretary, William Rawley, and part 1 of the philosophical works included in the Instauratio Magna. (shrink)

Rudolf Carnap is increasingly regarded as one of the most important philosophers of the twentieth century. He was one of the leading figures of the logical empiricist movement associated with the Vienna Circle and a central figure in the analytic tradition more generally. He made major contributions to philosophy of science and philosophy of logic, and, perhaps most importantly, to our understanding of the nature of philosophy as a discipline. In this volume a team of contributors explores the major themes (...) of his philosophy and discusses his relationship with the Vienna Circle and with philosophers such as Frege, Husserl, Russell, and Quine. New readers will find this the most convenient and accessible guide to Carnap currently available. Advanced students and specialists will find a conspectus of recent developments in the interpretation of Carnap. (shrink)

This intriguing volume provides a thorough examination of the historical roots of global climate change as a field of inquiry, from the Enlightenment to the late twentieth century. Based on primary and archival sources, the book is filled with interesting perspectives on what people have understood, experienced, and feared about the climate and its changes in the past. Chapters explore climate and culture in Enlightenment thought; climate debates in early America; the development of international networks of observation; the scientific transformation (...) of climate discourse; and early contributions to understanding terrestrial temperature changes, infrared radiation, and the carbon dioxide theory of climate. But perhaps most important, this book shows what a study of the past has to offer the interdisciplinary investigation of current environmental problems. (shrink)

A personal story of the ways in which persistence, chance, and creativity interact in biomedical research. This first book by the author of Zen and the Brain examines the role of chance in the creative process. James Austin tells a personal story of the ways in which persistence, chance, and creativity interact in biomedical research; the conclusions he reaches shed light on the creative process in any field. Austin shows how, in his own investigations, unpredictable events shaped the outcome (...) of his research and brought about novel results. He then goes beyond this story of serendipity to propose a new classification of the varieties of chance, drawing on his own research and examples from the history of science—including the famous accidents that led Fleming to the discovery of penicillin. Finally, he explores the nature of the creative process, considering not only the environmental and neurophysiological correlates of creativity but also the role of intuition in both scientific discoveries and spiritual quests. This updated MIT Press paperback edition includes a new introduction and recent material on medical research, creativity, and spirituality. (shrink)

Among the more significant developments of the twentieth century, the widespread attention given to 'rights issues' must surely justify ranking it somewhere near the top. Never before has the issue of rights attracted such a wide audience or stirred so much controversy. Until very recently 'rights' were traditionally recognized as attributable only to humans. Today, we increasingly are hearing a call to extend 'rights' to the nonhuman animal and, on occasion, to the environment. In this book, James B. Reichmann, (...) S.J., undertakes an investigation of the metaethical grounds of 'rights' theory, with special focus on the controversial issue of whether creatures other than humans can and should be considered true subjects of 'rights.' He contends that before assigning rights to this or that individual or group, whether human or not, we need to be very clear about what it is we are assigning, to whom, and why. The book argues forcefully that the various recent efforts to build a case supporting animal and environmental 'rights' fail in their quest, and that any such effort resting on a Darwinian evolutionary base is likewise condemned to fail. In furtherance of this claim the author first investigates life phenomena, followed by a detailed comparative study of knowing, communicating and doing, as these are observed in the human and the nonhuman animal. This in turn is followed by an overview of diverse views advanced by contemporary environmental ethicists and animal 'rights' advocates, including Peter Singer, Tom Regan, J. Baird Callicott, Laura Westra, and Don E. Marietta, Jr. Representative though doubtless provocative conclusions drawn from this study include the claims that: (1) Classic Darwinian theory provides no admissable premise from which to derive a theory of inherent, inalienable rights. (2) No satisfactory explanation of the origin of rights and obligation can derive save from within the context of natural law theory. (3) The human person alone unqualifiedly possesses rights. (4) The view that vegetarianism is an ethical mandate is neither compatible with the Christian world view, nor philosophically sound. ABOUT THE AUTHOR: James B. Reichmann, S.J., is professor emeritus of philosophy at Seattle University where he continues to teach. (shrink)

‘Immanent criticism' has been discussed by philosophers of quite different persuasions, working in separate areas and in different traditions of philosophy. Almost all of them agree on roughly the same story about its origins: It is that Hegel invented immanent criticism, that Marx later developed it, and that the various members of the Frankfurt School, particularly Adorno, refined it in various ways, and that they are all paradigmatic practitioners of immanent criticism. I call this the Continuity Thesis. There are four (...) different claims that interest me. Hegel is the originator of immanent criticism. Hegel's dialectical method is that of immanent criticism. Adorno practises immanent criticism and endorses the term as a description of his practice. Adorno's dialectical method is fundamentally Hegelian. In this article, I offer an account of immanent criticism, on the basis of which, I evaluate these four claims and argue that the Continuity Thesis should be rejected. (shrink)

This paper addresses the role of categories and dimensions in the classification of psychopathology. While psychopathology does not sort itself out neatly into natural categories, we do find rough, symptom-based groupings that, through refinement, become diagnostic categories. Given that these categories suffer from comorbidity, uncertain boundaries, and excessive “unspecified disorder” diagnoses, there has been a move toward refining the diagnoses with dimensional measures. The paper traces efforts both to improve the diagnostic categories with validators that allow at least partial validity (...) and to introduce dimensional measures into the diagnostic manual. Drawing from the philosophical pragmatism of Charles Sanders Peirce, William James, and John Dewey, which emphasizes the practical, effect-sensitive consequences of a theory along with an emphasis on empirical evidence and the progressive, probabilistic character of knowledge, the paper argues that these efforts must be guided both by scientific validity and clinical utility.

Scientists use a variety of modes of representation in their work, but philosophers have studied mainly sentences expressing propositions. I ask whether diagrams are mere conveniences in expressing propositions or whether they are a distinct, ineliminable mode of representation in scientific texts. The case of path analysis, a statistical method for quantitatively assessing the relative degree of causal determination of variation as expressed in a causal path diagram, is discussed. Path analysis presents a worst case for arguments against eliminability since (...) path diagrams are usually presumed to be mathematically or logically “equivalent” in an important sense to sets of linear path equations. I argue that path diagrams are strongly generative, i.e., that they add analytical power to path analysis beyond what is supplied by linear equations, and therefore that they are ineliminable in a strong scientific sense.

This article develops an interpretation and defense of Husserl’s account of the omnitemporality of idealities. I first examine why Husserl rejects the atemporality and temporal individuation of idealities on phenomenological grounds, specifically that these attributions prove countersensical in how they relate idealities to consciousness. As an alternative to these conceptions, I develop a two-sided interpretation of omnitemporality expressed in modal terms of actuality and possibility, the actual referring to appearances in time and the possible, to reactivation at any time. In (...) defense of this interpretation of omnitemporality, I consider influential criticisms against Husserl’s account of idealities as they concern time, particularly whether the historical genesis of idealities compromises their omnitemporality by binding them to time. Ultimately, I argue that the transcendental historicity of idealities, despite being relevant to the question of validity and access, proves indifferent to their omnitemporality. (shrink)

BackgroundPlagiarism is common and threatens the integrity of the scientific literature. However, its detection is time consuming and difficult, presenting challenges to editors and publishers who are entrusted with ensuring the integrity of published literature.MethodsIn this study, the extent of plagiarism in manuscripts submitted to a major specialty medical journal was documented. We manually curated submitted manuscripts and deemed an article contained plagiarism if one sentence had 80 % of the words copied from another published paper. Commercial plagiarism detection software (...) was utilized and its use was optimized.ResultsIn 400 consecutively submitted manuscripts, 17 % of submissions contained unacceptable levels of plagiarized material with 82 % of plagiarized manuscripts submitted from countries where English was not an official language. Using the most commonly employed commercial plagiarism detection software, sensitivity and specificity were studied with regard to the generated plagiarism score. The cutoff score maximizing both sensitivity and specificity was 15 % (sensitivity 84.8 % and specificity 80.5 %).ConclusionsPlagiarism was a common occurrence among manuscripts submitted for publication to a major American specialty medical journal and most manuscripts with plagiarized material were submitted from countries in which English was not an official language. The use of commercial plagiarism detection software can be optimized by selecting a cutoff score that reflects desired sensitivity and specificity. (shrink)

Medical assistance in dying was legalized in Canada in 2016. As of July 2017, approximately 2149 patients have accessed MAID. There remains no national-level data on the perspectives of future physicians about MAID or its changing legal status. We provide evidence from a national survey of Canadian medical students about their opinions, intentions, and concerns about MAID. From October 2016 to July 2017, we distributed an anonymous online survey to all students at 15 of Canada’s 17 medical schools. The survey (...) collected data on respondent socio-demographic characteristics, features of their medical education, intentions for medical practice, and perspectives on MAID. We analyzed responses using univariate descriptive and stepwise multivariate logistic regression. In 1210 completed surveys, 71% of respondents reported being willing to provide MAID under a legal framework that permits it. Non-religious respondents reported greater willingness to participate in MAID than respondents of any religious affiliation. Frequency of religious attendance was inversely associated with willingness to provide MAID. Medical students born in Québec were more willing to provide MAID than respondents from other provinces. Age, sex, socioeconomic status, year of medical study, previous academic major, and rural/urban city of birth were not associated with willingness to provide MAID. As the current class of medical students becomes the first cohort of new physicians to enter Canada’s changing medical and legal landscape around MAID, our findings inform the public debate by examining attributes associated with support or opposition to the practice.

Research shows that a high majority of parents receiving prenatal diagnosis of intellectual disability terminate pregnancy. They have reasons for rejecting a child with intellectual disabilities—these reasons are, most commonly, beliefs about quality of life for it or them. Without a negative evaluation of intellectual disability, their choice makes no sense. Disability-based abortion has been critiqued through virtue ethics for being inconsistent with admirable moral character. Parental selectivity conflicts with the virtue of acceptingness and exhibits the vice of wilfulness. In (...) this paper I claim that, beyond failures of moral virtue, disability abortion often involves failures of epistemic virtue on the part of parents. I argue two things: parents believe something false, or at least contested, about life with intellectual disability—and they do so because they are not epistemically conscientious. I first explain why a central motivation for disability abortion—that it prevents harm to the child—is mistaken. I next give a brief account of intellectual virtue and culpable ignorance. I then indicate why many parents fail to be intellectually virtuous when choosing to terminate pregnancy. I focus on elimination of intellectual disability and have little to say about physical and sensory impairments. (shrink)

The locked-in syndrome is a state of profound paralysis with preserved awareness of self and environment who typically results from a brain stem stroke. Although patients in LIS have great difficulty communicating, their consciousness, cognition, and language usually remain intact. Medical decision-making by LIS patients is compromised, not by cognitive impairment, but by severe communication impairment. Former systems of communication that permitted LIS patients to make only “yes” or “no” responses to questions was sufficient to validate their consent for simple (...) medical decisions but not for consequential medical decisions such as whether to refuse further life-sustaining therapy. Emerging technologies including computer-tracking assistance of retained partial motor function and brain-computer interfaces promise to improve the communication ability of LIS patients and, when better developed, will allow them to fully exercise their right to actively participate in consequential medical decisions about their own medical care. Although so-called “covert cognition” patients clinically diagnosed as vegetative state that are shown to be aware by functional neuroimaging maybe metaphorically considered locked-in, it is nosologically more coherent not to categorize them formally as LIS.

In a way, it's a book Augustine has written about each of us. Popular speaker and award-winning author James K. A. Smith has spent time (...) on the road with Augustine, and he invites us to take this journey too, for this ancient African thinker knows far more about us than we might expect. Following Smith's successful You Are What You Love, this book shows how Augustine can be a pilgrim guide to a spirituality that meets the complicated world we live in. Augustine, says Smith, is the patron saint of restless hearts--a guide who has been there, asked our questions, and knows our frustrations and failed pursuits. Augustine spent a lifetime searching for his heart's true home and he can help us find our way. "What makes Augustine a guide worth considering," says Smith, "is that he knows where home is, where rest can be found, what peace feels like, even if it is sometimes ephemeral and elusive along the way." Addressing believers and skeptics alike, this book shows how Augustine's timeless wisdom speaks to the worries and struggles of contemporary life, covering topics such as ambition, sex, friendship, freedom, parenthood, and death. As Smith vividly and colorfully brings Augustine to life for 21st-century readers, he also offers a fresh articulation of Christianity that speaks to our deepest hungers, fears, and hopes. (shrink)

In this paper I argue that selective abortion for disability often involves inadequate counselling on the part of reproductive medicine professionals who advise prospective parents. I claim that prenatal disability clinicians often fail in intellectual duty—they are culpably ignorant about intellectual disability. First, I explain why a standard motivation for selective abortion is flawed. Second, I summarize recent research on parent experience with prenatal professionals. Third, I outline the notions of epistemic excellence and deficiency. Fourth, I defend culpable ignorance as (...) the best explanation of inadequate disability counselling. Fifth, I rebut alternative explanations. My focus is pregnancies diagnosed with mild or moderate intellectual disability. (shrink)

This book conveys the breadth and interconnectedness of questions of justice - a rarity in contemporary moral and political philosophy. James P. Sterba argues that a minimal notion of rationality requires morality, and that a minimal libertarian morality requires the welfare and equal opportunity endorsee by welfare liberals and the equality endorsed by socialists, as well as a full feminist agenda. Feminist, racial, homosexual, and multicultural justice, are also shown to be mutually supporting. The author further shows the compatibility (...) between anthropocentric and biocentric environmental ethics, as between just war and pacifist theories. Finally, he spells out when normal politics, legal protest, civil disobedience, revolutionary action, and criminal disobedience are morally permitted by justice for here and now. This highly original and potentially controversial book is ideal for courses in moral and political philosophy, applied ethics, women's studies, environmental studies, and peace studies. (shrink)

_Lyotard and the Political_ is the first book to consider the full range of the political thought of the French philosopher François Lyotard and its broader implications for an understanding of the political. James Williams clearly and carefully traces the development of Lyotard's thought from his early Marxist essays on the Algerian struggle for independence to his break with the thought of Marx and Freud. This is compared with Lyotard's later, highly influental writings on the politics of desire and (...) his attempts to base a postmodern political discourse on the sublime. An indispensable work for all who are interested in modern continental philosophy, _Lyotard and the Political_ offers the first systematic analysis of the political dimension of the work of one of the most controversial and influential philosophers of the twentieth century.

In this book, distinguished theologian and political scientist James V. Schall explores Maritain's political philosophy, demonstrating that Maritain understood society, state, and government in the tradition of Aristotle and Aquinas, of natural law and human rights and duties. Schall pays particular attention to the ways in which evil appears in political forms, and how this evil can be dealt with morally.

Physicists use different theories to describe the world on different scales. In particular, they use the standard model of particle physics at very high energies, but move to various effective field theories, such as quantum electrodynamics, when modelling lower energy scattering processes. One way to explain this methodological fact is pragmatic in spirit. According to this view, physicists move to an effective field theory at lower energies in order to extract predictions and qualitative understanding which would be difficult or impossible (...) to extract directly from a more fundamental theory. By contrast, another way of accounting for the methodological data is metaphysical in spirit. On this view, the reason that physicists use different theories at different scales is that the world actually exhibits different nomic structure on different scales. These two positions have recently been thrown into sharp relief in a debate between Woodward (2016) and Batterman (2021), with Woodward taking the pragmatist line and Batterman the metaphysical line. One difficulty with the metaphysical answer is that its content is unclear: in what sense exactly could an effective field theory provide a better representation of the nomic structure of the world in its domain of applicability than our world’s fundamental theory? This talk attempts to provide an answer to this question by developing a simple metaphysical model. I start by assuming a set of possible worlds which are nomically possible according to some fundamental theory (I suggest that one is free to adopt either a Humean or Non-Humean view of these fundamental nomic necessities). I then introduce an equivalence relation between possible worlds: two worlds are scale-E equivalent if they assign the same values to physical quantities below energy scale E (up to some finite level of precision P). The key question now is whether this relation induces equivalence classes on the set of nomically possible worlds. I argue that in the case of current quantum field theories this does indeed occur, as evidenced by the possibility of “integrating out” high energy degrees of freedom in the renormalisation group framework. The formation of equivalence classes in the fundamental theory's possibility space indicates that some of its high energy features do not make a difference to its low energy dynamical behaviour. This suggests the following reading of the claim that an effective field theory provides a better representation of the nomic structure of the world in its domain of applicability: the solutions of the effective field theory stand in one-to-one correspondence with equivalence classes induced by the scale-E equivalence relation, whereas the fundamental theory overcounts the physical possibilities which are relevant at scale E. In this sense, the effective field theory provides a more natural representation of low energy physics than the fundamental theory. I conclude by explaining how this metaphysical model offers a reduction compatible understanding of multiple realisability, once again pointing to renormalisation group results in quantum field theory to support this.

Kuhn argued that scientific theory choice is, in some sense, a rational matter, but one that is not fully determined by shared objective scientific virtues like accuracy, simplicity, and scope. Okasha imports Arrow’s impossibility theorem into the context of theory choice to show that rather than not fully determining theory choice, these virtues cannot determine it at all. If Okasha is right, then there is no function (satisfying certain desirable conditions) from ‘preference’ rankings supplied by scientific virtues over competing theories (...) (or models, or hypotheses) to a single all-things-considered ranking. This threatens the rationality of science. In this paper we show that if Kuhn’s claims about the role that subjective elements play in theory choice are taken seriously, then the threat dissolves. (shrink)
