There have been many objections to the possibility oftime travel. But all the truly interesting ones concern the possibility of reversecausation. What is objectionable about reverse causation? I diagnose that the trulyinteresting objections are to a further possibility: that of causal loops. I raisedoubts about whether there must be causal loops if reverse causation obtains; but devote themajority of the paper to describing, and dispelling concerns about, various kinds ofcausal loop. In short, I argue that they are neither logically nor (...) physically impossible.The only possibly objectionable feature that all causal loops share is that coincidenceis required to explain them. Just how coincidental a loop will be varies: some arereally quite ordinary, and some are incredibly unlikely. I end by speculating thatthe tendency amongst physicists to avoid discussion of causal loops involving intentionalaction may have been unfortunate, since intentional action is an excellent way tonon-mysteriously bring about what otherwise would have been an unlikely coincidence. Hencecausal loops may be more likely in a world with beings like us, than in one without. (shrink)

Categorical perception (CP) is said to occur when a continuum of equally spaced physical changes is perceived as unequally spaced as a function of category membership (Harnad, S. (Ed.) (1987). Psychophysical and cognitive aspects of categorical perception: A critical overview. Cambridge: Cambridge University Press). A common suggestion is that CP for color arises because perception is qualitatively distorted when we learn to categorize a dimension. Contrary to this view, we here report that English speakers show no evidence of lowered discrimination (...) thresholds at the boundaries between blue and green categories even though CP is found at these boundaries in a supra-threshold task. Furthermore, there is no evidence of different discrimination thresholds between individuals from two language groups (English and Korean) who use different color terminology in the blue-green region and have different supra-threshold boundaries. Our participants' just noticeable difference (JND) thresholds suggest that they retain a smooth continuum of perceptual space that is not warped by stretching at category boundaries or by within-category compression. At least for the domain of color, categorical perception appears to be a categorical, but not a perceptual phenomenon. (shrink)

Thought experiments involving The Matrix, brains-in-vats, or Cartesian demons have traditionally thought to describe skeptical possibilities. Chalmers has denied this, claiming that the simulations involved are real enough to at least sometimes defeat the skeptic. Through an examination of the meaning of kind terms in natural language I argue that, though the Chalmers view may be otherwise attractive, it is not an antidote to skepticism.

Professor Richard Hanley faced the dilemma plaguing so many philosophy professors today—how to entice students into the classroom. Based upon his own successful course, Is Data Human presents a thoroughly unique and enjoyable way of introducing students to the basic concepts of philosophy as seen through the lens of Star Trek. From the nature of a person, of minds, and of consciousness, to ethics and morality, to the nature and extent of knowledge and free will, Hanley brings (...) a fresh perspective to the contemporary debates concerning humankind’s place in the world.Dare to boldly go where no philosophy professor has gone before—a classroom packed with eager and enthusiastic students.

Critical realism is the view that fictional characters arecontingent, actual, abstract individuals, ontologically on a par with such things as plots and rhyme schemes, andquantified over in statements such as “A character inHamlet is a prince.” A strong contender for thecorrect account of fictional characters, critical realismnevertheless has difficulty satisfying all that we intuitivelyrequire of such an account.

Universities and colleges all over the United States are currently revising and implementing policies concerning sexual harassment and sexual misconduct, under the generally expressed concern to comply with Title IX requirements. But there is a very basic problem of equivocation. Both “sexual harassment” and “sexual misconduct” are used in very different ways in different contexts, often by the same entity. The result is a mess in which members of campus communities cannot be sure of their obligations or protections, and which (...) presents a serious threat to academic freedom. (shrink)

A minor philosophical industry has sprung up in recent years defending the possibility and epistemic utility of miracles: supernatural interventions in the world by a Christian God. By examining some staples of science fiction, this chapter finds a way to agree: miracles are possible, and could tell us something about reality. Nobody is sure exactly what David Hume himself thought, but there is an identifiable Humean tradition on miracles. It makes two main points. First, by definition a miracle is in (...) some relevant sense beyond what the laws of nature can describe and explain. The second point is intended to generally undermine claims of an established marvel which is contrary to our understanding of the laws of nature; to prevent a miracle claim even getting a toehold. The chapter then focuses on three miracle monger's favorite Sci‐Fi things: time travel, other dimensions, and simulations. (shrink)

Peter Singer does not think that eating meat is wrong in and of itself. The case he makes in Practical Ethics against the use of non-human animals for food consists of two connected arguments.1 It will be convenient to call them the Suffering Argument and the Killing Argument. The Suffering Argument is primarily an argument against factory farm- ing—the mass production of meat and animal products as it occurs in developed nations at least—and is well expressed by paraphrasing an explicit (...) argument Singer gives (230–231) concerning absolute poverty.

Cloning scares the hell out of people, because the idea of cloning people scares the hell out of people. Some of this fear is well-founded. Like any new reproductive technology, the cloning of entire human organisms can be put to good or bad effect, for good or bad reasons. But much of the fear is not well-founded. Before you could say “Hello, Dolly,” the U.S. administration moved to ban federal funding of human cloning research; and there is considerable support in (...) Congress for an outright ban on the use of somatic cell nuclear transfer technology for the purpose of human cloning. Why? Here is part of Clinton’s statement announcing the funding ban. (shrink)

An examination of a somewhat neglected topic in the ethics of warfare: the training and treatment of one's own forces. The creation of clone soldiers with diminished autonomy in _Star Wars_ has parallels with actual military training procedures that reinforce obedience by manipulating nurture rather than nature. I argue that objections to cloning and eugenics in general do not have much force in mounting a case against the use of diminished clones. Indeed, there likely are situations in which training and (...) deploying such soldiers is preferable to standard military practice. (shrink)

Invaluable wisdom on living a good life from the founder of modern economics Adam Smith is best known today as the founder of modern economics, but he was also an uncommonly brilliant philosopher who was especially interested in the perennial question of how to live a good life. Our Great Purpose is a short and illuminating guide to Smith's incomparable wisdom on how to live well, written by one of today's leading Smith scholars. In this inspiring and entertaining book, Ryan (...) Patrick Hanley describes Smith's vision of "the excellent and praiseworthy character," and draws on the philosopher's writings to show how each of us can go about developing one. For Smith, an excellent character is distinguished by qualities such as prudence, self-command, justice, and benevolence—virtues that have been extolled since antiquity. Yet Smith wrote not for the ancient polis but for the world of market society—our world—which rewards self-interest more than virtue. Hanley shows how Smith set forth a vision of the worthy life that is uniquely suited to us today. Full of invaluable insights on topics ranging from happiness and moderation to love and friendship, Our Great Purpose enables modern readers to see Smith in an entirely new light—and along the way, learn what it truly means to live a good life.

Fénelon may be the most neglected of all the major early modern philosophers. His political masterwork was the most-read book in eighteenth-century France after the Bible, yet today even specialists rarely engage his work directly. This problem is particularly acute in the Anglophone world, for while Fénelon's works have been published in several excellent modern French editions, only the smallest fraction of his vast and influential corpus has appeared in modern English translation. This volume aims to help remedy this by (...) bringing to English-language audiences the first collection of his moral and political writings in translation. By so doing it hopes to make more widely available the riches of one of the leading voices of resistance to the absolutism of Louis XIV. Fénelon's political thought will thus be of particular interest to students and scholars of French history, as well as to those today engaged in questions of political resistance and reform. But Fénelon's reach also extends to fields well beyond politics and ethics. In the Enlightenment, Fénelon came to be celebrated not only as a humanitarian political reformer but also as a pioneering theorist of education, a prescient student of economics and international relations, and a key voice in contemporary philosophical debates-not to mention his fame as one of the seventeenth-century's most preeminent theologians and spiritualists and masters of French prose. As such, his work will be of interest to students and scholars in fields ranging from philosophy and political science to economics, education, literature, French history, and religion. (shrink)

The essential guide to the life, thought, and legacy of Adam Smith Adam Smith (1723–90) is perhaps best known as one of the first champions of the free market and is widely regarded as the founding father of capitalism. From his ideas about the promise and pitfalls of globalization to his steadfast belief in the preservation of human dignity, his work is as relevant today as it was in the eighteenth century. Here, Ryan Hanley brings together some of the (...) world's finest scholars from across a variety of disciplines to offer new perspectives on Smith's life, thought, and enduring legacy. Contributors provide succinct and accessible discussions of Smith's landmark works and the historical context in which he wrote them, the core concepts of Smith's social vision, and the lasting impact of Smith's ideas in both academia and the broader world. They reveal other sides of Smith beyond the familiar portrayal of him as the author of the invisible hand, emphasizing his deep interests in such fields as rhetoric, ethics, and jurisprudence. Smith emerges not just as a champion of free markets but also as a thinker whose unique perspective encompasses broader commitments to virtue, justice, equality, and freedom. An essential introduction to Adam Smith's life and work, this incisive and thought-provoking book features contributions from leading figures such as Nicholas Phillipson, Amartya Sen, and John C. Bogle. It demonstrates how Smith's timeless insights speak to contemporary concerns such as growth in the developing world and the future of free trade, and how his influence extends to fields ranging from literature and philosophy to religion and law.

The neurological criteria for the determination of death remain controversial within secular and Catholic circles, even though they are widely accepted within the medical community. In Determining Death by Neurological Criteria, Matthew Hanley offers both a practical and a philosophical defense. Hanley shows that the criteria are often misapplied in clinical settings, leading to cases where persons declared dead apparently spontaneously revive. These instances are often connected to a rushed decision to retrieve donated organs, thus undermining the trust (...) of the public in organ donation. Hanley calls on health care institutions to take seriously their obligation to establish strict protocols for the determination of death, including who may conduct the examinations. From a broader perspective, Hanley considers how the criteria rely on a philosophical conception of the person as a living organism whose unity disintegrates at death. This view, he notes, corresponds to the Catholic conviction that the soul is the life-principle of the body, which departs at death, bringing about the destruction of the body-soul composite. The Vatican, recognizing that death is a medical judgment, has generally given its approval to the criteria. Hanley also reviews the many and various objections offered by detractors, including against the use of the apnea test, which is faulted as a practice that sometimes hastens death. The problem of the continued presence of certain vital functions within the deceased body of the brain dead is explored in detail, with reference to particular cases and to solutions proposed by leading physicians and bioethicists. Hanley likewise addresses the dilemma of having two separate standards for death, one neurological and the other cardiopulmonary. Given the possibility of resuscitation following loss of the cardio-circulatory system, he concludes that the neurological criteria must be the true standard. Stoppage of the heart leads swiftly to the final necrosis of the brain. -- Provided by publisher. (shrink)

Kant's views on sex and marriage deserve the renewed attention of political scientists for three reasons. First, Kant's theory of marriage was shaped by his engagement with Rousseau's political thought and especially his Social Contract—a key if unappreciated side of his engagement with Rousseau. Second, Kant's application of Rousseau's political theory to marriage suggests an egalitarian view of marriage's nature and function that helpfully illuminates marriage's role in a liberal society of free and equal persons. Third, in appropriating Rousseau's egalitarianism (...) for his theory of marriage, Kant transfers his foundational concern with equality from the public to the private sphere: a move that suggests liberal political institutions require more than mere commitment to procedural neutrality for their perpetuation but require also a commitment to equality best cultivated by certain types of private associations and personal relationships.

The Exchange of Words is a philosophical exploration of human testimony, specifically as a form of intersubjective understanding in which speakers communicate by making themselves accountable for the truth of what they say. This account weaves together themes from philosophy of language, moral psychology, action theory, and epistemology, for a new approach to this basic human phenomenon.

The paper argues for the centrality of believing the speaker (as distinct from believing the statement) in the epistemology of testimony, and develops a line of thought from Angus Ross which claims that in telling someone something, the kind of reason for belief that a speaker presents is of an essentially different kind from ordinary evidence. Investigating the nature of the audience's dependence on the speaker's free assurance leads to a discussion of Grice's formulation of non-natural meaning in an epistemological (...) light, concentrating on just how the recognition of the speaker's self-reflexive intention is supposed to count for his audience as a reason to believe P. This is understood as the speaker's explicitly assuming responsibility for the truth of his statement, and thereby constituting his utterance as a reason to believe. (shrink)

In this volume Rorty offers a Deweyan account of objectivity as intersubjectivity, one that drops claims about universal validity and instead focuses on utility for the purposes of a community. The sense in which the natural sciences are exemplary for inquiry is explicated in terms of the moral virtues of scientific communities rather than in terms of a special scientific method. The volume concludes with reflections on the relation of social democratic politics to philosophy.

Richard Swinburne offers an original treatment of a question at the heart of epistemology: what makes a belief rational, or justified in holding? He maps the rival accounts of philosophers on epistemic justification ("internalist" and "externalist"), arguing that they are really accounts of different concepts. He distinguishes between synchronic justification (justification at a time) and diachronic justification (synchronic justification resulting from adequate investigation)--both internalist and externalist. He also argues that most kinds of justification are worth having because they are (...) indicative of truth; however, it is only justification of internalist kinds that can guide a believer's actions. Swinburne goes on to show the usefulness of the probability calculus in elucidating how empirical evidence makes beliefs probably true. (shrink)

Richard Swinburne presents a powerful new case for substance dualism and for libertarian free will. He argues that pure mental events are distinct from physical events and interact with them, and claims that no result from neuroscience or any other science could show that interaction does not take place. Swinburne goes on to argue for agent causation, and claims that it is we, and not our intentions, that cause our brain events. It is metaphysically possible that each of us (...) could acquire a new brain or continue to exist without a brain; and so we are essentially souls. Brain events and conscious events are so different from each other that it would not be possible to establish a scientific theory which would predict what each of us would do in situations of moral conflict. Hence, we should believe that things are as they seem to be: that we make choices independently of the causes which influence us. It follows that we are morally responsible for our actions. (shrink)

This paper explores some aspects of the relation between different ways of achieving a consensus on the judgemental values of a group of indviduals; in particular, aggregation and deliberation. We argue firstly that the framing of an aggregation problem itself generates information that individuals are rationally obliged to take into account. And secondly that outputs of the deliberative process that this initiates is in tension with constraints on consensual values typically imposed by aggregation theory, at least when deliberation is modelled (...) as process of learning from others compatible with Bayesian updating principles.

Atheism is a familiar kind of skepticism about religion. Moral error theory is an analogous kind of skepticism about morality, though less well known outside academic circles. Both kinds of skeptic face a "what next?" question: If we have decided that the subject matter (religion/morality) is mistaken, then what should we do with this way of talking and thinking? The natural assumption is that we should abolish the mistaken topic, just as we previously eliminated talk of, say, bodily humors and (...) unicorns. The fictionalist, however, offers a less obvious recommendation. According to the fictionalist, engaging in the topic in question provides pragmatic benefits that do not depend on its truth-in a way roughly analogous to engaging with a novel or a movie. The religious fictionalist maintains that even if we were atheists, we should carry on talking, thinking, and acting as if religion were true. The moral fictionalist maintains a similar view regarding moral talk, thought, and action. Both forms of fictionalism face serious challenges. Some challenges can be levelled at either form of fictionalism (or at any form of fictionalism), whereas others are problems unique to moral fictionalism or to religious fictionalism. There are important questions to be asked about the relationship between these two kinds of fictionalism. Could moral fictionalism be plausible even if religious fictionalism is not (or vice versa)? This is a volume of thirteen previously unpublished papers on the topics of religious fictionalism, moral fictionalism, and the relation between these views. (shrink)
