Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief polarization as the product of epistemic irrationality. In contrast, we argue that the persistent disagreement that grounds political and social polarization can be produced by epistemically rational agents, when those agents have limited cognitive resources. Using an agent-based model of group deliberation, we show that groups of deliberating agents using coherence-based strategies for managing their limited resources tend (...) to polarize into different subgroups. We argue that using that strategy is epistemically rational for limited agents. So even though group polarization looks like it must be the product of human irrationality, polarization can be the result of fully rational deliberation with natural human limitations. (shrink)

In his book A Theory of Justice, John Rawls introduces and employs the concept of “reflective equilibrium” as a method of testing which of rival moral theories is to be preferred. The introduction of this concept is plainly a significant event for moral philosophy. The criterion by which we decide to reject, say, utilitarianism in favour of a contractual theory of justice is, if anything, even more fundamental than the choice of theory itself, since our choice of moral theory may (...) well be determined by the criterion we use.

Many people believe that all human life is of equal value. Most of them also believe that all human beings have a moral status superior to that of nonhuman animals. But how are these beliefs to be defended? The mere difference of species cannot in itself determine moral status. The most obvious candidate for regarding human beings as having a higher moral status than animals is the superior cognitive capacity of humans. People with profound mental retardation pose a problem for (...) this set of beliefs, because their cognitive capacities are not superior to those of many animals. I argue that we should drop the belief in the equal value of human life, replacing it with a graduated view that applies to animals as well as to humans. (shrink)

A novel of of ideas, expressed in the birth, life, and early death of Oliver Alden. Published in 1935, George Santayana's The Last Puritan was the American philosopher's only novel. It became an instant best-seller, immediately linked in its painful voyage of self discovery to The Education of Henry Adams. It is essentially a novel of ideas, expressed in the birth, life, and early death of Oliver Alden.The Last Puritan is volume four in a new critical edition of The Works (...) of George Santayana that restores Santayana's original text and provides important new scholarly information. Books in this series - the first complete publication of Santayana's works - include an editorial apparatus with notes to the text, textual commentary, discussions of adopted readings, lists of variants and emendations, and line-end hyphenations. Irving Singer's new introduction to this edition takes up Santayana's philosophical and artistic concerns, including issues of homosexuality raised by the depiction of the novel's two protagonists, Oliver and Mario, and of the relationship between Oliver and the rogue character Jim Darnley. In his thoughtful analysis Singer finds the term "homosexual novel" too reductionist and imprecise for what Santayana is trying to achieve. Singer brings to light the author's skillful and inventive methods for perceiving and interpreting reality, including ideal forms of friendship, and his success in exploring the pervasive moral problems that people face throughout their existence.

For more than thirty years, in most of the world, the irreversible cessation of all brain function, more commonly known as brain death, has been accepted as a criterion of death. Yet the philosophical basis on which this understanding of death was originally grounded has been undermined by the long-term maintenance of bodily functions in brain dead patients. More recently, the American case of Jahi McMath has cast doubt on whether the standard tests for diagnosing brain death exclude a condition (...) in which the patient is not dead, but in a minimally conscious state. I argue that the evidence now clearly shows that brain death is not equivalent to the death of the human organism. We therefore face a choice: either we stop removing vital organs from brain dead patients, or we accept that it is not wrong to kill an innocent human who has irreversibly lost consciousness.

In Animal Liberation I argued that we commonly ignore or discount the interests of sentient members of other species merely because they are not human, and that this bias in favour of members of our own species is, in important respects, parallel to the biases that lie behind racism and sexism. Shelly Kagan, in ‘What's Wrong With Speciesism’ misconstrues this argument, as well as the principle of equal consideration of interests, which I offer as an alternative to speciesism. Kagan also (...) offers, as an alternative explanation of, and possible justification for, our discounting the interests of nonhuman animals, the suggestion that your interests count more if you are a member of a species whose typical adult members are persons. Although this view is not a form of speciesism, Kagan seems not to be aware of the fact that it is a view commonly defended by advocates of natural law ethics, on which there is already an extensive critical literature.

Though ‘evil’ is often used loosely as merely the generic opposite of ‘morally good’, used precisely it is the worst possible term of opprobrium available. In this essay it is taken as applying primarily to persons, secondarily to conduct; evil deeds must flow from the volition to do something evil. An evil action is one so horrendously bad that no ordinary decent human being can conceive of doing it, and an evil person is one who knowingly wills or orders such (...) actions. Malignant evil—doing evil because it is evil—is not just possible but real, and is one of several kinds of evil delineated. There are incidental discussions of cruelty, Rosenbaum on Explaining Hitler, Baumeister on Evil, and Benn on wickedness.

To challenge my students to think about the ethics of what we owe to people in need, I ask them to imagine that their route to the university takes them past a shallow pond. One morning, I say to them, you notice a child has fallen in and appears to be drowning. To wade in and pull the child out would be easy but it will mean that you get your clothes wet and muddy, and by the time you go (...) home and change you will have missed your first class. (shrink)

The traditional solutions to the Sleeping Beauty problem say that Beauty should have either a sharp 1/3 or sharp 1/2 credence that the coin flip was heads when she wakes. But Beauty’s evidence is incomplete so that it doesn’t warrant a precise credence, I claim. Instead, Beauty ought to have a properly imprecise credence when she wakes. In particular, her representor ought to assign \(R(H\!eads)=[0,1/2]\) . I show, perhaps surprisingly, that this solution can account for the many of the intuitions (...) that motivate the traditional solutions. I also offer a new objection to Elga’s restricted version of the principle of indifference, which an opponent may try to use to collapse the imprecision. (shrink)

The aim of this paper is to discuss popular conceptions of business ethics and their relationship to the problem of racial injustice by way of reviewing Spike Lee’s (1989) _Do the Right Thing_. Taking place on one day in late 80’s Bedford-Stuyvesant, and set against a tense decade of racial conflict in New York City, Spike Lee’s masterpiece has deeply influenced American discourse on race, capturing many of the complex interpersonal dynamics that are both constitutive and consequence of American racial (...) hierarchies. Instead of focusing on shareholders and stakeholders, I argue that _Do The Right Thing_ suggests a more political understanding of business’s ethical obligations: a business’s ethical obligations don’t emanate from internal relations but from its social and political position. I conclude by discussing a more recent film, Steve McQueen’s (2020) _Mangrove_. Like _Do the Right Thing_, _Mangrove_ also focuses on a business that is at the center of an urban racial conflict, but which stands in a very different relationship to this tension, providing an alternative illustration of business ethics informed by political and social positioning.

:Corporations cannot exist, scholars rightly note, without being constituted by government. However, many take a further step, claiming that corporations are normatively distinct from other market actors because of this governmental provenance. They are mistaken. Like corporations, markets and contracts also require government for their creation. Governmental provenance does not distinguish corporations normatively because our coercive social institutions are pro tanto justified in re-arranging both corporate and non-corporate market activities on behalf of social and political values. The corporation is distinct (...) only practically and prudentially, in that it represents a more proximate instrument for effecting morality in the economy. (shrink)

Over the last few years, the public has gradually become aware of the existence of a new cause: animal liberation. Most people first heard of the movement through newspaper articles, often of the "what on earth will they come up with next?" variety. Then there were marches and demonstrations against factory farming, animal experimentation or the Canadian seal slaughter; all brought to an audience of millions by the TV cameras. Finally there have been the illegal acts: slogans daubed on fur (...) shops, laboratories broken into and animals rescued. What are the ideas behind the animal liberation movement, and where is it heading? In this essay I shall try to answer these questions. (shrink)

Medicine and health care generate many bioethical problems and dilemmas that are of great academic, professional and public interest. This comprehensive resource is designed as a succinct yet authoritative text and reference for clinicians, bioethicists, and advanced students seeking a better understanding of ethics problems in the clinical setting.

“The question has, as I have already said, been a central concern of moral philosophers from the time of Plato until the Nineteenth Century. It would be tedious to list the philosophers who have discussed the issue, for the list would exclude hardly any of the major moral philosophers of the past. The names of some of them will occur in the course of this thesis.” … “In the Conclusion, I consider the present state of the question and argue that (...) 'Why should I be moral?', despite its age-old importance, has yet to be answered. I maintain that the question is vital not only to the individual but also to society, and that if changes are made on a social level, it may be possible to answer it. This raises issues of political philosophy. A society in which the question could .be answered would be a step closer to being an ideal society than a society in which this is not the case.”.

Recently, some unusual research has raised new questions about the role of intuitive responses in ethical reasoning. Joshua Greene, a philosophy graduate now working in psychology who has recently moved from Princeton University to Harvard, studied how people respond to a set of imaginary dilemmas. In one dilemma, you are standing by a railroad track when you notice that a trolley, with no one aboard, is heading for a group of five people. They will all be killed if the trolley (...) continues on its current track. (shrink)

This paper examines a number of questions about the degree to which the clinical practice of medicine is affected, if at all, by the legal systems in four countries: Chile, Germany, Japan and the United States. The focus on these four countries in four different regions of the world offers a unique perspective within which to examine medical treatment decisions made by patients and their proxies or surrogates, the potential role for universal written instruments such as advance directives, the cross-professional (...) tensions between clinical and legal concerns in very distinct cultures, and the degree to which legal activities can change or affect clinical realities in the context of these different political and health care systems. We have incorporated, whenever relevant, the insights of many disciplines, including the social sciences, in analyzing the existing interrelations between law and behavior in this specific context. Der Beitrag untersucht, inwieweit die klinische Praxis in vier Ländern mit unterschiedlichen Rechtssystemen und Berufskulturen durch Rechtsnormen oder das Verständnis von Recht beeinflußt wird. Es wird gefragt, welche Funktion rechtliche Interventionen bei der Veränderung von Verhaltensnormen in unterschiedlichen Gesundheitssystemen haben können. Folgende Themenbereiche werden diskutiert: Entscheidungen über die medizinische Behandlung, die von Patienten und ihren Angehörigen oder Stellvertretern getroffen werden; die mögliche Rolle umfassender schriftlicher Verfügungen wie z.B. der Patiententestamente ; die berufsübergreifenden Spannungen zwischen medizinischen und rechtlichen Belangen in sehr unterschiedlichen Kulturen; der Einfluß, den gesetzgeberische Aktivitäten im Kontext der verschiedenen politischen und Gesundheitssysteme auf die medizinische Wirklichkeit haben. Bei ihrer Analyse der in diesem Zusammenhang bestehenden Beziehungen im Verhältnis von Recht und Verhalten haben die Autoren die Erkenntnisse vieler Disziplinen unter Einschluß der Sozialwissenschaften, soweit sie als relevant erscheinen, in ihren Beitrag eingearbeitet.

In this paper I present the basic outlines of a nonstandard interpretation of Sein und Zeit. The merit of this interpretation is that it brings out and develops some of the radical possibilities contained in this rich text, possibilities which, I believe, have yet to be given their due. On the basis of this interpretation it is clear not only how Heidegger’s ontology departs from its Cartesian and Kantian predecessors, but also how his ontology puts the traditional mind/body problem, and (...) the problem of the external world, onto radically new grounds. However, unlike standard interpretations of Sein und Zeit, I argue that these new grounds neither resolve, nor dissolve, these problems, and that Heidegger’s discussion of the so-called “scandal of philosophy” is misleading at best.

I am grateful to Professor Erler for his thoughtful commentary. As I have been asked to be quite brief in my response, I will move directly to what appear to me to be the most interesting points of contention between us. There are three of them.

Thirty years ago, in The New York Review of Books, I reviewed a pioneering work of what was to become the new animal rights movement. The book was a collection of essays called Animals, Men and Morals. I headed my review "Animal Liberation", a title that invited - and received - ridicule. But I used it deliberately, to say that just as we needed to overcome prejudices against black people, women and gays, so too we should strive to overcome our (...) prejudices against non-human animals and start taking their interests seriously.

This is exciting medical researchers because it means that, at least in theory, the cells from an early embryo could eliminate the need for organ transplants entirely, cure leukaemia, enable people with diabetes to manufacture insulin, treat Parkinson's and Alzheimer's disease, and repair the nerve systems of quadriplegics. Though these prospects are still far from realisation, results achieved by Oliver Brustle at the University of Bonn Medical Centre have brought them a step closer. In an article published in Science on (...) July 30, Brustle reported that he was able to repair the damaged nervous systems of rats using cells taken from embryos. (shrink)

This book is about bridging the current deeply-held divide between sentience and reason. It focuses on the pragmatic role of sentient experience and its unceasing and inseparable interplay with the exercise of reason. Part I of the book deals first with the need for synthesizing the hitherto separate "truth-finding" knowledge traditions: the third-personal scientific-technological, and the first-personal humanistic-wisdom tradition. A conceptual framework for a mind reality is then proposed. Drawing from the unifying natural laws in current physical and biological sciences, (...) the mind reality is portrayed in terms of one interlocking open dynamic system with both a manifested and a covert aspect. In this entire system, each individual mind constantly "co-creates" and "co-evolves" with other collective or group minds at various levels. It is also presumed that the basic unit of interaction in the mind reality is thought or intent. Supporting evidence from psychology, parapsychology and the ancient perennial philosophies is presented. The second part of the book addresses the pragmatic consequences of the proposed mind reality. At the individual level, it is argued that sentient experience can serve the function of guiding, affirming and fostering an individual's life's work. A selection of existing first-personal accounts is presented to illustrate this point. At the collective level, the current dominant collective thought of "new capitalism" has the unfortunate consequences for humanity's sense of freedom, education and morality. Such consequences pertain to the "exteriorization" and the "deconstruction" of the intrinsic self and intrinsic values. To avoid this to happen, a collective effort at changing consciousness becomes necessary: the core task lies with the closure of the reason and sentience divide. (shrink)

It may be thought odd that these two philosophers should have been selected for discussion together. They had no special connection with each other. They were not personally close. They did not teach or write in the same place. Nor were their personalities at all similar. None the less there are similarities of thought and perspective that make the conjunction illuminating.It may be thought even odder that these two philosophers should have been selected for discussion at all. After all, who (...) today reads them, or has even heard of them? Very few. If they ever were in fashion, they are not in fashion now. But this situation results from ignorance, which this series aims to dispel. Remember, it was meant to be a revelation to the ignorant as well as an inspiration. (shrink)

Marcel Gauchet spoke of the “eclipse of the political” during the neo-liberal era, but with the rise of populism he is now forced to speak of a “revenge of the political”. As the eclipse was discussed in terms of a new era of individualization, understood as the culmination of the “disenchantment of the world”, one has a right to ask what is the place of individualization in the era of the political’s revenge, particularly as, in the face of Covid 19, (...) the refusal to wear masks is couched in terms of the defense of individual liberties? In what is an immanent critique of Gauchet’s claims, individualization is considered under four rubrics: abstract individualization vs. concrete socialization; the dilemmas of recognition; rejection of alterity; and the loss of the sense of the social. The paper concludes that the “revenge” should be understood as a revenge of an “anti-political” politics. (shrink)

I am, naturally, greatly honoured to have been invited by the Royal Institute of Philosophy to organize and conduct their lecture series on American Philosophy. It has been an interesting if trying experience, and I must say that the process of organizing it has given me a special respect for the patience and administrative capacities of those who have the task year in year out. Of course there were special difficulties in the way of importing so many people from the (...) United States, but if the series was to be on American Philosophy—whatever that is—it seemed especially appropriate that the lectures be given predominantly by Americans who have made a special study of the subject— again, whatever that is. We may, of course, end with the conclusion that there is no such distinctive subject, and that the name ‘American Philosophy’ is as nominal as a name can be, but that, we should note, is something to be found out, not a conclusion dictated in advance.

As an Australian citizen, I voted in the recent federal election there. So did about 95% of registered Australian voters. That figure contrasts markedly with elections in the United States, where the turnout in the 2004 presidential election barely exceeded 60%. In Congressional elections that fall in the middle of a president’s term, usually fewer than 40% of eligible Americans bother to vote.

For this special issue dedicated to Jonathan Glover, Peter Singer was asked to reflect on the influence that the book Causing Death and Saving Lives had on him, as well as the Glover seminar in Oxford that Peter Singer attended in the late 1960s. One of Peter Singer's recurring arguments is the criticism of the traditional distinction between acts and omissions. But Glover is no stranger to this questioning, even if the two thinkers do not seem to (...) want to draw exactly the same conclusions. What is at stake is this: what are we really responsible for and how demanding should our morality be? (shrink)
