Multiple -conclusion logic extends formal logic by allowing arguments to have a set of conclusions instead of a single one, the truth lying somewhere among the conclusions if all the premises are true. The extension opens up interesting possibilities based on the symmetry between premises and conclusions, and can also be used to throw fresh light on the conventional logic and its limitations. This is a sustained study of the subject and is certain to stimulate further research. Part I reworks (...) the fundamental ideas of logic to take account of multiple conclusions, and investigates the connections between multiple - and single - conclusion calculi. Part II draws on graph theory to discuss the form and validity of arguments independently of particular logical systems. Part III contrasts the multiple - and the single - conclusion treatment of one and the same subject, using many-valued logic as the example; and Part IV shows how the methods of 'natural deduction' can be matched by direct proofs using multiple conclusions.

The mainstream rationale for equating brain death (BD) with death is that the brain confers integrative unity upon the body, transforming it from a mere collection of organs and tissues to an organism as a whole. In support of this conclusion, the impressive list of the brains myriad integrative functions is often cited. Upon closer examination, and after operational definition of terms, however, one discovers that most integrative functions of the brain are actually not somatically integrating, and, conversely, most integrative (...) functions of the body are not brain-mediated. With respect to organism-level vitality, the brains role is more modulatory than constitutive, enhancing the quality and survival potential of a presupposedly living organism. Integrative unity of a complex organism is an inherently nonlocalizable, holistic feature involving the mutual interaction among all the parts, not a top-down coordination imposed by one part upon a passive multiplicity of other parts. Loss of somatic integrative unity is not a physiologically tenable rationale for equating BD with death of the organism as a whole. (shrink)

Vendler’s :161–173, 1979) puzzle about imagination is that the sentences ‘Imagine swimming in that water’ and ‘Imagine yourself swimming in that water’ seem at once semantically different and semantically the same. They seem semantically different, since the first requires you to imagine ’from the inside’, while the second allows you to imagine ’from the outside.’ They seem semantically the same, since despite superficial dissimilarity, there is good reason to think that they are syntactically and lexically identical. This paper sets out (...) the puzzle and offers a novel solution. Our proposal is that, just as there is knowledge-wh, there is also imagining-wh and that the inside/outside distinction Vendler points to is properly understood as a distinction within imagining-wh. In particular, to imagine swimming from the inside is to imagine what it feels like to swim, while to imagine swimming from the outside is to imagine what it looks like to swim. We show that this proposal is well grounded in both the semantics and syntax of ‘imagine.’ We also argue it makes better sense than its rivals of the data Vendler found so puzzling. (shrink)

In debates about criteria for human death, several camps have emerged, the main two focusing on either loss of the "organism as a whole" (the mainstream view) or loss of consciousness or "personhood." Controversies also rage over the proper definition of "irreversible" in criteria for death. The situation is reminiscent of the proverbial blind men palpating an elephant; each describes the creature according to the part he can touch. Similarly, each camp grasps some aspect of the complex reality of death. (...) The personhood camp, in contrast to the mainstream "organism" camp, recognizes that a human organism can still be a biological living whole even without brain function. The mainstream camp, in contrast to the personhood camp, recognizes that a person can be permanently, even irreversibly unconscious, and still be a living person so long as his/her body is alive. The author proposes that hylomorphic dualism incorporates both these key insights. But to complete the picture of the entire "death elephant," a fundamental paradigm shift is needed to make sense of other seemingly conflicting insights. The author proposes a "semantic bisection" of the concept of death, analogous to the traditional distinction at the beginning of life between "conception" and "birth." To avoid the semantic baggage associated with the term "death," the two new death-related concepts are referred to as "passing away" (or "deceased") and "deanimation," corresponding, respectively, to sociolegal ceasing-to-be (mirror image of birth) and ontological/theological ceasing-to-be of the bodily organism (mirror image of conception). Regarding criteria, the distinguishing feature is whether the cessation of function is permanent (passing away) or irreversible (deanimation). If the "dead donor rule" were renamed the "deceased donor rule" (both acronyms felicitously being "DDR"), the ethics of organ transplantation from non–heart-beating donors could, in principle, be validly governed by the DDR, even though the donors are not yet ontologically "deanimated." Thus, the paradigm shift satisfies both those who insist on maintaining the DDR and those who claim that it has all along been receiving only lip service and should be explicitly loosened to include those who are "as good as dead." Even so, a number of practical caveats remain to be worked out for non–heart-beating protocols. (shrink)

Many medical ethicists accept the thesis that there is no moral difference between withholding and withdrawing life-sustaining therapy. In this paper, we offer an interesting counterexample which shows that this thesis is not always true. Withholding is distinguished from withdrawing by the simple fact that therapy must have already been initiated in order to speak coherently about withdrawal. Provided that there is a genuine need and that therapy is biomedically effective, the historical fact that therapy has been initiated entails a (...) claim to continue therapy that cannot be attributed to patients who have not yet received therapy. This intrinsic difference between withholding and withdrawing therapy is of moral importance. In many instances, patients will waive this claim. But when one considers withdrawing therapy from one patient to help another in a setting of scarce resources, this intrinsic moral difference comes into sharp focus. In an era of shrinking medical resources, this difference cannot be ignored. (shrink)

OBJECTIVE: To examine the long-term effects of an innovative curriculum on medical house officers' (HOs') knowledge, confidence, and attitudes regarding medical ethics. DESIGN: Long term cohort study. The two-year curriculum, implemented by a single physician ethicist with assistance from other faculty, was fully integrated into the programme. It consisted of monthly sessions: ethics morning report alternating with didactic conferences. The content included topics such as ethics vocabulary and principles, withdrawing life support, informed consent, and justice. Identical content was offered simultaneously (...) at the largest affiliated community hospital. SETTING: A multi-hospital university training programme from July, 1992 to June, 1994. PARTICIPANTS: Thirty-nine HOs responded in 92. Thirty HOs from the same cohort responded in 94 (response rates = 83% v 71%; P = 0.19). RESULTS: The curriculum was well received, with 96% of HOs finding the sessions stimulating. Previously validated scales of knowledge and confidence were administered at baseline and at follow-up. The average knowledge score improved 14% (P < 0.001). Confidence also improved, rising from 3.3 to 3.8 on a 5-point Likert scale (P < 0.001). These findings were independent of age, gender, religion, and prior education. The only attitudinal change was an increase in the proportion of residents who thought that ethics should be a required part of residency training (57% v 80%, P = 0.05). CONCLUSION: This curriculum appears practical, popular, and effective. It should be readily transferable to other institutions. (shrink)

Clark and Chalmers (1998) defend the hypothesis of an ‘Extended Mind’, maintaining that beliefs and other paradigmatic mental states can be implemented outside the central nervous system or body. Aspects of the problem of ‘language acquisition’ are considered in the light of the extended mind hypothesis. Rather than ‘language’ as typically understood, the object of study is something called ‘utterance-activity’, a term of art intended to refer to the full range of kinetic and prosodic features of the on-line behaviour of (...) interacting humans. It is argued that utterance activity is plausibly regarded as jointly controlled by the embodied activity of interacting people, and that it contributes to the control of their behaviour. By means of specific examples it is suggested that this complex joint control facilitates easier learning of at least some features of language. This in turn suggests a striking form of the extended mind, in which infants’ cognitive powers are augmented by those of the people with whom they interact. (shrink)

Bioethicists are increasingly commenting on health care resource allocation, and sometimes suggest ways to solve various rationing dilemmas ethically. I argue that both because of the assumptions bioethicists make about social reality, and because of the methods of argument they use, they cannot possibly make a useful contribution to the debate. Bioethicists who want to make a practical difference should either approach health care resource allocation as if the matter hinged upon tribal competition (which is essentially what it does), or (...) they should do political philosophy in the traditional sense, and examine the health system from the outside.

In this paper we will offer a few examples to illustrate the orientation of contemporary research in data analysis and we will investigate the corresponding role of mathematics. We argue that the modus operandi of data analysis is implicitly based on the belief that if we have collected enough and sufficiently diverse data, we will be able to answer most relevant questions concerning the phenomenon itself. This is a methodological paradigm strongly related, but not limited to, biology, and we label (...) it the microarray paradigm. In this new framework, mathematics provides powerful techniques and general ideas which generate new computational tools. But it is missing any explicit isomorphism between a mathematical structure and the phenomenon under consideration. This methodology used in data analysis suggests the possibility of forecasting and analyzing without a structured and general understanding. This is the perspective we propose to call agnostic science, and we argue that, rather than diminishing or flattening the role of mathematics in science, the lack of isomorphisms with phenomena liberates mathematics, paradoxically making more likely the practical use of some of its most sophisticated ideas.

In this paper I discuss the important yet overlooked role played by time in public health ethics, clinical ethics, and personal ethics, and present an exploratory analysis of temporal inequalities and temporal autonomy.

A diagonal version of the strong reflection principle is introduced, along with fragments of this principle associated with arbitrary forcing classes. The relationships between the resulting principles and related principles, such as the corresponding forcing axioms and the corresponding fragments of the strong reflection principle, are analyzed, and consequences are presented. Some of these consequences are “exact” versions of diagonal stationary reflection principles of sets of ordinals. We also separate some of these diagonal strong reflection principles from related axioms.

"Deductivism" is the thesis that all logic is deductive. Stove lays out the arguments for the existence of non-deductive logic.

This article suggests that Chomsky’s notorious ‘London’ argument against semantics looks much more plausible that it is usually interpreted as being when seen in the light of something apparently remote from its concerns, viz., David Lewis’s distinction between natural and non-natural properties.

Francis Beckwith’s Defending life: a moral and legal case against abortion choice defends the pro-life position on moral, legal and political grounds. In this critical notice I consider three key issues and argue that Beckwith’s treatment of each of them is unpersuasive. The issues are: (1) whether abortion is politically justified by the principle that we should err on the side of liberty in the face of reasonable disagreement over the moral status of the fetus; (2) whether the fetus’s natural (...) capacity or genetic propensity to develop rationality and communication is sufficient to give it a moral right to life; and (3) whether abortion is morally justified on the basis of bodily rights. I also show that Beckwith’s book fails to consider several important issues and arguments. (shrink)

In 1982, Jonsen, Siegler and Winslade published Clinical Ethics, in which they described the “four quadrants” approach, a new method of analysing clinical ethics cases. Although the book is now in its 6th edition, a literature search has revealed only one academic paper demonstrating the method at work. This paper is an attempt to start filling this gap. As a way of describing and testing the approach, I apply the four quadrants method to a detailed clinical ethics case. The analysis (...) is interspersed with reflections on the method itself. It is hoped that this experiment will encourage ethicists and clinicians to devote more attention to this neglected approach. (shrink)

To say that coronavirus is highly visible is a massive understatement in terms of its omnipresence in our lives and media coverage concerning it, yet also clearly untrue in terms of the virus itself. COVID-19 is our invisible enemy, changing our lives radically without ever revealing itself directly. In this paper I explore its invisibility and how it relates to and exposes other invisible enemies we are and have been fighting, in many cases without even realizing. First, I analyse the (...) virus itself and how its stealthy nature has transformed our lives. Second, I describe how the invisible epidemic of social media sharing of fake news about the virus worsens the situation further. Third, I explore how the virus has revealed to us what really matters in our lives and has forced us to re-evaluate our priorities. Fourth, I go on to explore the underlying structural weaknesses and disparities in society that have been exposed by the virus but previously remained unconsidered for so long that they too have become camouflaged, even if their effects are all too apparent; like the virus, neoliberal capitalism is an invisible enemy that has made prisoners of us all. I conclude by suggesting that the coronavirus pandemic represents a hidden opportunity to overcome perhaps the biggest invisible enemy of all: the moral distance that separates us from others. Only by rendering the rest of humanity morally visible to ourselves can we overcome capitalism and stop treating other people as invisible enemies. (shrink)

Powers and Faden argue that social justice ‘is concerned with securing and maintaining the social conditions necessary for a sufficient level of well-being in all of its essential dimensions for everyone’ (2006: 50). Moreover, social justice is concerned with the ‘achievement of well-being, not the freedom or capability to achieve well-being’ (p. 40). Although Powers and Faden note that an agent alone cannot achieve well-being without the necessary social conditions of life (e.g. equal civil liberties and basic material resources, such (...) as food and shelter), it seems that achievement requires that an agent actually pursue the six dimensions of well-being. In this article, I question the extent to which an individual has an obligation to achieve well-being, even if he or she would choose to do otherwise. For example, can an agent choose to forgo being healthy even if all the social conditions are met in her life, thereby choosing to not achieve well-being? It remains unclear how the dimension of self-determination coheres with the remaining five dimensions of well-being and the extent of society’s obligations toward an individual’s achievement of well-being, even in those instances when society’s actions may go against an individual’s right to self-determination.

In a recent article in this journal our unit was accused of a number of errors of judgment in applying covert video surveillance (CVS) to infants and children suspected of life-threatening abuse. The article implied, that on moving from the Royal Brompton Hospital in London to North Staffordshire Hospital, we failed to present our work to the Research Ethics Committee (REC). We did send our protocol to the REC though we did not consider that, after a total of 16 patients (...) had been documented as being the subject of life-threatening abuse, this was research. The REC in Staffordshire agreed with us. We were also accused of undertaking work that should be pursued by the Police. We agree with this. However, unlike the Metropolitan Police the Staffordshire Police would not undertake CVS. We fail to agree that 'working together' with parents is necessarily practical or safe when trying to protect children from life-threatening abuse of this kind. (shrink)

The computer has increasingly become the principal model for the mind, which means our most basic experience of ""reality"" is as mediated through a screen, or stored in a cloud. As a result, we are losing a sense of the concrete and imposing presence of the real, and the fundamental claim it makes on us, a claim that Iris Murdoch once described as the essence of love. In response to this postmodern predicament, the present book aims to draw on the (...) classical philosophical tradition in order to articulate a robust philosophical anthropology, and a new appreciation of the importance of the ""transcendental properties"" of being: beauty, goodness, and truth. The book begins with a reflection on the importance of metaphysics in our contemporary setting, and then presents the human person's relation to the world under the signs of the transcendentals: beauty is the gracious invitation into reality, goodness is the self-gift of freedom in response to this invitation, and truth is the consummation of our relation to the real in knowledge. The book culminates in an argument for why love is ultimately a matter of being, and why metaphysical reason in indispensable in faith. ""Philosopher D. C. Schindler defies the dragon of modernity, whose dominant thought patterns induce a life- and culture-threatening loss of reality and self. He offers life-giving proposals regarding love, being, and the transcendentals to restore us profoundly to the world and to ourselves as humans. Buy the book--you may divest yourself of others. Digest it, and revel in your already-involvement with a responsive reality--an involvement of intimate encounter and communion; a reality that is love, fraught with beauty, goodness, and truth."" --Esther Lightcap Meek, Geneva College ""Love and the Postmodern Predicament is a treasure trove of philosophical riches. Schindler does not merely indicate the need to return to metaphysics to wrestle successfully with what he carefully and accurately describes as our postmodern predicament, but in fact leads us out of that predicament. His profound and original reflections on love, grounded in the transcendental properties of being, are a radical refashioning of traditional metaphysical principles."" --Jonathan J. Sanford, University of Dallas ""In this rewarding little text, Schindler accomplishes something too rare among works of philosophy: he accommodates a wide audience and yet deftly draws the reader into deep metaphysical waters, into a consideration of some of the most profound and perennial philosophical concerns. Throughout, the timeliness of his reflections on love, beauty, God, and the good remains in clear view. This is a highly recommended work by an author of capacious intellect and generous spirit."" --Lee M. Cole, Hillsdale College D. C.

Sexual abuse of minors by Catholic priests has been a persistent and widespread problem in the Church. Although more than 80 percent of victims have been boys, prior studies have rejected the idea that the abuse is related to homosexuality among priests. Available data show, however, that the proportion of homosexual men in the priesthood is correlated almost perfectly with the percentage of male victims and with the overall incidence of abuse. Data also show that while the incidence of abuse (...) is lower today than it was three decades ago, it has not declined as much as is commonly believed, and has recently begun to rise amid signs of episcopal complacency about procedures for the protection of children.

Throughout his lengthy career Arthur Danto made significant and original contributions to action theory, historical narrative, and epistemology. He became best known however for his work as an art critic in the Nation, Artnews and elsewhere, and for his philosophical publications on art theory, beginning with his early (1964) article “The Artworld.” In fact, Danto’s views on art are emblematic of his overall philosophy: he managed to reconcile conflicting philosophical sensibilities without short-schrifting them. He appreciates both Hegel and postmodernism, but (...) his own philosophy is a good deal less radical than most postmodernisms in that he denies that philosophy is a radically historicist enterprise.

Myths, misunderstanding and neglect have combined to obscure our understanding of the relationship between left-wing politics and Darwinian science. This article seeks to redress the balance by studying how radical and socialist thinkers of the late nineteenth and early twentieth centuries, desperate to legitimate their work with scientific authority, wrestled with the paradoxical challenges Darwinism posed for their politics. By studying eight leading radical and socialist thinkers — ranging from the co-founder of the theory of evolution by natural selection, Alfred (...) Russel Wallace, through to Britain's first Labour Prime Minister, J. Ramsay MacDonald — this article analyses the often tortuous relationship between Darwinism and the left, as well as providing fresh insights into the historiographical debate over ‘continuity’ in radicalism and socialism. A strict definition of ‘Darwinian’ is adopted throughout, in order to help us delineate what was specifically ‘Darwinian’ from what merely reflected the general evolutionary ethos of the age, in left-wing thought, and to move us beyond the sensational and distorting focus on eugenics which has characterized previous studies.

This paper, written from the perspective of a liberal Protestant, addresses Karl Barth’s famous dispute with his predecessor Friedrich Schleiermacher. It claims that despite the vehemence he often employs against Schleiermacher, a careful assessment of Barth reveals an ever-shifting ambivalence. Barth’s dismissal was very much a heated reaction amidst post-war circumstances, and Schleiermacher served as a symbol for aspects of pre-war culture and theology that are not necessarily reflective of Schleiermacher’s original project. Later in his career, Barth seems to have (...) yearned to rehabilitate aspects of that very project. (shrink)

Over decades of teaching systematic theology at Union Theological Seminary (New York), Christopher Morse has set out to salvage “dogmatics” as a postmodern theological discipline that nevertheless retains a (more or less literal) construal of the apocalyptic gospel message. This article attempts to clarify this project in conversation with William James’ best-known work on religious belief.

This article, which appeared in the Library of Living Philosophers series, is a thought experiment that imagines Danto’s analytical framework reaching well beyond what he had called the “drab” state of philosophy in the early 2000s. It describes, in minimalist terms, what he saw as the fundamental project of all philosophy -- regardless of the specific theoretical content any particular philosopher might put forth. It discusses his central (and still underdeveloped) notion of representation, and his quasi-Hegelian view of how art (...) theory has been altered by its own recently emerging self-consciousness. It draws out the implications of his Argument from Intelligibility, which informs Danto’s interest in human self-consciousness, in autonomy, and (somewhat speculatively) in “spirit.”. (shrink)

Readers new to Santayana may feel puzzled by aspects of Scepticism and Animal Faith (1923). A number of Santayana’s early critics were puzzled as well. Some found the relation between scepticism and common sense troublesome. Others were put off by Santayana’s indirect poetic style and his lack of “clarity.” In this paper I reflect on these topics, as well as the relation between his poetic style and his vision of philosophical truth and sublimity. This should illuminate his “discovery” of essence, (...) which he re-enacts in this book and which holds the key to understanding Santayana’s mature project. (shrink)

In 2000, a simple, foundational thermodynamic paradox was proposed: a sealed blackbody cavity contains a diatomic gas and a radiometer whose apposing vane surfaces dissociate and recombine the gas to different degrees (A $_{2} \rightleftharpoons $ 2A). As a result of differing desorption rates for A and A $_{2}$ , there arise between the vane faces permanent pressure and temperature differences, either of which can be harnessed to perform work, in apparent conflict with the second law of thermodynamics. Here we (...) report on the first experimental realization of this paradox, involving the dissociation of low-pressure hydrogen gas on high-temperature refractory metals (tungsten and rhenium) under blackbody cavity conditions. The results, corroborated by other laboratory studies and supported by theory, confirm the paradoxical temperature difference and point to physics beyond the traditional understanding of the second law.

Dewey’s view of art “as experience” takes the art object proper to be distinct from the physical artifact. The "work of art" is a label for a set of perceptual procedures in relation to a complex "situation" – one that is pregnant with vitality and saturated with “pervasive quality.” This qualitative trait is organic rather than merely mechanical in that the informed percipient’s sensibilities have already been sufficiently “funded” with a repertoire of emotionally imbued responses that culminate in a distinctive (...) “consummatory” experience. This account intends to combine classic notions of intrinsicality and instrumentality into a general story about art, which gets elevated into an honorific trait of human life generally -- all within a naturalistic framework.
