Four experiments investigated how people judge the plausibility of category-based arguments, focusing on the diversity effect, in which arguments with diverse premise categories are considered particularly strong. In Experiment 1 we show that priming people as to the nature of the blank property determines whether sensitivity to diversity is observed. In Experiment 2 we find that people's hypotheses about the nature of the blank property predict judgements of argument strength. In Experiment 3 we examine the effect of our priming methodology (...) on people's tendency to bring knowledge about causality or similarity to bear when evaluating arguments, and in Experiment 4 we show that whether people's hypotheses about the nature of the blank property were causal predicted ratings of argument strength. Together these results suggest that diversity effects occur because diverse premises lead people to bring general features of the premise categories to mind. Although our findings are broadly consistent with Bayesian and Relevance-based approaches to category-based inductive reasoning, neither approach captures all of our findings. (shrink)

Over the course of its first seven editions, Principles of Biomedical Ethics has proved to be, globally, the most widely used, authored work in biomedical ethics. It is unique in being a book in bioethics used in numerous disciplines for purposes of instruction in bioethics. Its framework of moral principles is authoritative for many professional associations and biomedical institutions-for instruction in both clinical ethics and research ethics. It has been widely used in several disciplines for purposes of teaching in the (...) classroom, during conferences, etc. (shrink)

More than twenty years after its original publication, The Case for Animal Rights is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

For forty years, successive editions of Ethical Theory and Business have helped to define the field of business ethics. The 10th edition reflects the current, multidisciplinary nature of the field by explicitly embracing a variety of perspectives on business ethics, including philosophy, management, and legal studies. Chapters integrate theoretical readings, case studies, and summaries of key legal cases to guide students to a rich understanding of business ethics, corporate responsibility, and sustainability. The 10th edition has been entirely updated, ensuring that (...) students are exposed to key ethical questions in the current business environment. New chapters cover the ethics of IT, ethical markets, and ethical management and leadership. Coverage includes climate change, sustainability, international business ethics, sexual harassment, diversity, and LGBTQ discrimination. New case studies draw students directly into recent business ethics controversies, such as sexual harassment at Fox News, consumer fraud at Wells Fargo, and business practices at Uber. (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.

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.

Can the theory that reality is a simulation be tested? We investigate this question based on the assumption that if the system performing the simulation is nite (i.e. has limited resources), then to achieve low computational complexity, such a system would, as in a video game, render content (reality) only at the moment that information becomes available for observation by a player and not at the moment of detection by a machine (that would be part of the simulation and whose (...) detection would also be part of the internal computation performed by the Virtual Reality server before rendering content to the player). Guided by this principle we describe conceptual wave/particle duality experiments aimed at testing the simulation theory. (shrink)

Political theorists agree that justice is a fundamental political value but disagree profoundly about its proper analysis and philosophical justification. This substantially revised and updated second edition of Tom Campbell's highly acclaimed and widely used text provides a much-expanded overview of the nature and scope of justice, as well as presenting clear exposition and critiques of the principal contending theorists of most relevance to the contemporary world.

Tom Beauchamp presents a new edition, designed especially for the student reader, of An Enquiry concerning Human Understanding, the classic work in which David Hume gave a general exposition of his philosophy to a broad educated readership. An authoritative new version of the text is preceded by a substantial introduction explaining the historical and intellectual background to the work and surveying its main themes. The volume also includes detailed explanatory notes on the text, a glossary of terms, and a section (...) of supplementary readings. (shrink)

This paper examines the causal basis of our ability to attribute emotions to music, developing and synthesizing the existing arousal, resemblance and persona theories of musical expressivity to do so. The principal claim is that music hijacks the simulation mechanism of the brain, a mechanism which has evolved to detect one's own and other people's emotions.

In this book, Tom Cochrane develops a new control theory of the emotions and related affective states. Grounded in the basic principle of negative feedback control, his original account outlines a new fundamental kind of mental content called 'valent representation'. Upon this foundation, Cochrane constructs new models for emotions, pains and pleasures, moods, expressive behaviours, evaluative reasoning, personality traits and long-term character commitments. These various states are presented as increasingly sophisticated layers of regulative control, which together underpin the architecture of (...) the mind as a whole. Clearly structured and containing numerous diagrams and examples to illustrate the discussion, this study draws on the latest research from fields including philosophy, psychology and neuroscience, and will appeal to readers interested in the philosophy and cognitive science of emotion.

It is an important feature of creatures like us that our various motivations compete for control over our behaviour, including mental behaviour such as imagining and attending. In large part, this competition is adjudicated by the stimulation of affect — the intrinsically pleasant or unpleasant aspects of experience. In this paper I argue that the motivation-affect system controls a sub-type of attention called 'alerting attention' to bring various goals and stimuli to consciousness and thereby prioritize those contents for action. This (...) view allows me to flesh out the global workspace theory of consciousness, as well as some of the phenomenal characteristics of conscious experience. (shrink)

: Phenomena of moral conflict and disagreement have led writers in ethics to two antithetical conclusions: Either valid moral distinctions hold universally or they hold relative to a particular and contingent moral framework, and so cannot be applied with universal validly. Responding to three articles in this issue of the Journal that criticize his previously published views on the common morality, the author maintains that one can consistently deny universality to some justified moral norms and claim universality for others. Universality (...) is located in the common morality and nonuniversality in other parts of the moral life, called "particular moralities." The existence of universal moral standards is defended in terms of: (1) a theory of the objectives of morality, (2) an account of the norms that achieve those objectives, and (3) an account of normative justification (both pragmatic and coherentist).

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.

We ask whether it is reasonable to delay or refuse to take COVID-19 vaccines that have been shown in clinical trials to be safe and effective against infectious diseases. We consider two kinds of vaccine hesitancy. The first is geared to scientifically informed open questions about vaccines. We argue that in cases where the data is not representative of relevant groups, such as pregnant women and ethnic minorities, hesitancy can be reasonable on epistemic grounds. However, we argue that hesitancy is (...) not reasonable if a vaccine has passed well-conducted clinical trials. The second kind of hesitancy is to do with beliefs about the institutions offering a successfully trialled vaccine and the justifiability of cooperating with those institutions. For example, in the UK, distrust of the UK Government or the National Health Service is identified as a factor in the vaccine hesitancy of minority ethnic populations. We ask whether this sort of hesitation is reasonable given normative requirements of fair co-operation, both with those institutions and the wider population. We suggest that the answer is not straightforward. Sometimes the hesitation is unreasonable but understandable. -/- . (shrink)

John Dewey is celebrated for his work in the philosophy of education and acknowledged as a leading proponent of American pragmatism. His philosophy of logic, on the other hand, is largely unheard of. In Dewey's New Logic, Burke analyzes portions of the debate between Dewey and Bertrand Russell that followed the 1938 publication of Dewey's Logic: The Theory of Inquiry. Burke shows how Russell failed to understand Dewey, and how Dewey's philosophy of logic is centrally relevant to contemporary developments in (...) philosophy and cognitive science. Burke demonstrates that Russell misunderstood crucial aspects of Dewey's theory and contends that logic today, having progressed well beyond Russell's early views, is approaching Dewey's broader perspective. -/- "[This] book should be of substantial interest not only to Dewey scholars and other historians of twentieth-century philosophy, but also to devotees of situation theory, formal semantics, philosophy of mind, cognitive science, and Artificial Intelligence."--Georges Dicker, Transactions of the C.S. Peirce Society "No scholar, thus far, has offered such a sophisticated and detailed version of central themes and contentions in Dewey's Logic . This is a pathbreaking study."--John J. McDermott, editor of The Philosophy of John Dewey. (shrink)

For forty years, acclaimed photographer and native Minnesotan Tom Arndt has been documenting the faces of Minnesota with unparalleled skill and candor. In Home, Arndt presents what he calls "a poem to my home state" through a series of poignant and compelling photographs that highlight the unique character of Minnesota. From Franklin Avenue in Minneapolis to Main Street in Willmar, from carnival workers at the state fair to drag racing fans in Anoka, and from small town street dances to the (...) sidewalks of Minneapolis, Home captures everyday life in the North Star State. By allowing people's lives to speak for themselves, Arndts photographs reveal the often forgotten moments that build common bridges across a diverse and ever-changing state. Enriched with more than 100 photographs, along with a personal and insightful preface by the author and a foreword by Garrison Keillor, Home is a landmark testimony to the people and culture of Minnesota. Arndt approaches his subjects - he would call them neighbors - with honesty, empathy, and humanity, and what emerges is a portrait of Minnesota that is at once achingly familiar and surprisingly new.

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)

Principles that provide general normative frameworks in bioethics have been criticized since the late 1980s, when several different methods and types of moral philosophy began to be proposed as alternatives or substitutes. Several accounts have emerged in recent years, including: (1) Impartial Rule Theory (supported in this issue by K. Danner Clouser), (2) Casuistry (supported in this issue by Albert Jonsen), and (3) Virtue Ethics (supported in this issue by Edmund D. Pellegrino). Although often presented as rival methods or theories, (...) these approaches are consistent with and should not be considered adversaries of a principle-based account. (shrink)

In 2012, a new and promising gene manipulation technique, CRISPR-Cas9, was announced that seems likely to be a foundational technique in health care and agriculture. However, patents have been granted. As with other technological developments, there are concerns of social justice regarding inequalities in access. Given the technologies’ “foundational” nature and societal impact, it is vital for such concerns to be translated into workable recommendations for policymakers and legislators. Colin Farrelly has proposed a moral justification for the use of patents (...) to speed up the arrival of technology by encouraging innovation and investment. While sympathetic to his argument, this article highlights a number of problems. By examining the role of patents in CRISPR and in two previous foundational technologies, we make some recommendations for realistic and workable guidelines for patenting and licensing. (shrink)

Tom Campbell is well known for his distinctive contributions to legal and political philosophy over three decades. In emphasising the moral and political importance of taking a positivist approach to law and rights, he has challenged current academic orthodoxies and made a powerful case for regaining and retaining democratic control over the content and development of human rights. This collection of his essays reaches back to his pioneering work on socialist rights in the 1980s and forward from his seminal book, (...) The Legal Theory of Ethical Positivism (1996). An introductory essay provides an historical overview of Professor Campbell's work and argues for the continuing importance of 'democratic positivism' at a time when it is again becoming clear that courts are ineffective protectors of human rights.

We argue that abduction does not work in isolation from other inference mechanisms and illustrate this through an inference scheme designed to evaluate multiple hypotheses. We use game theory to relate the abductive system to actions that produce new information. To enable evaluation of the implications of this approach we have implemented the procedures used to calculate the impact of new information in a computer model. Experiments with this model display a number of features of collective belief-revision leading to consensus-formation, (...) such as the influence of bias and prejudice. The scheme of inferential calculations invokes a Peircian concept of ‘belief’ as the propensity to choose a particular course of action. (shrink)

The last twenty-five years of published literature and curriculum development in bioethics suggest that the field enjoys a successful and stable marriage to philosophical ethical theory. However, the next twenty-five years could be very different. I believe the marriage is troubled. Divorce is conceivable and perhaps likely. The most philosophical parts of bioethics may retreat to philosophy departments, while bioethics continues on its current course toward a more interdisciplinary and practical field.I make no presumption that bioethics is integrally linked to (...) philosophical ethical theory. Indeed, I assume that the connection is contingent and fragile. Many individuals in law, theological ethics, political theory, the social and behavioral sciences, and the health professions carefully address mainstream issues of bioethics without finding ethical theory essential or breathtakingly attractive. This is not surprising. Moral philosophers have traditionally formulated theories of the right, the good, and the virtuous in the most general terms. (shrink)

According to a standard view, the physical boundary of the person—the skin-and-skull boundary—matters morally because this boundary delineates between where the person begins and the world ends. On the basis of this view we make a distinction between invasive interventions that penetrate this boundary and non-invasive interventions that do not. The development of neuroprosthetics, however, raises questions about the significance of this boundary and the relationship between person and body. In particular it has been argued by appeal to the Extended (...) Mind thesis that mind and person can extend beyond the body, and hence the skin-and-skull boundary is of questionable significance. In this paper I argue that the Extended Mind thesis is consistent with the ethical relevance of the skin-and-skull barrier. Although it can be argued that cognitive processes and aspect of mind can extend beyond the skin-and-skull boundary as EM claims, it does not follow that the person is also extended beyond this boundary. The moral sense of person is closely related to the notion of person as a subject of experiences and this, in turn, is related to the sensory and somatosensory aspects of the body. The development of neuroprosthetics provides us with reason to see that persons can be variously embodied, but this is consistent with the functional and ethical significance of the skin-and-skull boundary.

“Applied ethics” has been the major growth area in North American philosophy in the last decade, yet a robust confidence and enthusiasm over its promise is far from universal in academic philosophy. It is considered nonphilosophical in West Germany, and has largely failed to penetrate British departments of philosophy. Whether it has any intellectually or pedagogically redeeming value is still widely debated in North America, where many who have tried to teach some area of applied ethics for the first time (...) have seen their courses grind to a halt in unresolvable quandaries, practical exigencies, or unavailable technical information. Consequently, some departments are at war over whether to hire or confer tenure on those who teach these subjects. Many also remain unconvinced that philosophical generalizations or theories can play any significant role in applied contexts. They may even doubt both that applied ethics is really ethics and that philosophy should accomodate this creature in its curriculum. (shrink)

Byrne's approach to the semifactual conditional captures the reasoning data. However, we argue that it does not account for the processes or principles by which people arrive at representations of even-if conditionals, upon which their reasoning is said to be based. Drawing upon recent work on the suppositional conditional we present such an account.

We are neither as pessimistic nor as optimistic as Elqayam & Evans (E&E). The consequences of normativism have not been uniformly disastrous, even among the examples they consider. However, normativism won't be going away any time soon and in the literature on causal Bayes nets new debates about normativism are emerging. Finally, we suggest that to concentrate on expert reasoners as an antidote to normativism may limit the contribution of research on thinking to basic psychological science.

The practice of obtaining informed consent has its history in, and gains its meaning from, medicine and biomedical research. Discussions of disclosure and justified nondisclosure have played a significant role throughout the history of medical ethics, but the term “informed consent” emerged only in the 1950s. Serious discussion of the meaning and ethics of informed consent began in medicine, research, law, and philosophy only around 1972.

After expressing our gratitude to the commentators for their valuable analyses and assessments of Principles of Biomedical Ethics, we respond to several particular critiques raised by the commentators under the following rubrics: the compatibility of different sets of principles and rules; challenges to the principle of respect for autonomy; connecting principles to cases and resolving their conflicts; the value of and compatibility of virtues and principles; common morality theory; and moral status. We point to areas where we see common agreement (...) with our commentators and respond to their critical evaluations. (shrink)
