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.

This engaging and accessible introduction to the philosophy of language provides an important guide to one of the liveliest and most challenging areas of study in philosophy. Interweaving the historical development of the subject with a thematic overview of the different approaches to meaning, the book provides students with the tools necessary to understand contemporary analytical philosophy. The second edition includes new material on: Chomsky, Wittgenstein and Davidson as well as new chapters on the causal theory of reference, possible worlds (...) semantics and semantic externalism.

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)

Scholars of eighteenth-century Scottish philosophy today tend to agree that Adam Smith, while deeply indebted to Hume, was also engaged in a comprehensive and creative transformation and extension of certain of Hume’s fundamental concepts. But what exactly did Smith take from Hume, and precisely how did he transform these concepts? This chapter traces Smith’s appropriation and transformation along five fronts: sympathy and humanity, justice and utility, judgment and impartiality, virtue and commercial society, and epistemology and religion. In so doing, it (...) aims to provide a synthetic account of previous scholarship on the Hume–Smith relationship and to supplement these accounts with an examination of several further points of contact that have yet to receive significant attention.

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.

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)

A selection of speeches and essays from the author's second decade as president of Yale University.

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 renowned biologist and thinker Richard Dawkins presents his most expansive work yet: a comprehensive look at evolution, ranging from the latest developments in the field to his own provocative views. Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims (...) swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism. Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world. (shrink)

The discussion of good and evil must not be confined to the sterile lecture halls of academics but related instead to ordinary human feelings, needs, and desires, says noted philosopher Richard Taylor. Efforts to understand morality by exploring human reason will always fail because we are creatures of desire as well. All morality arises from our intense and inescapable longing. The distinction between good and evil is always clouded by rationalists who convert the real problems of ethics into complex (...) philosophical puzzles. In the first part of Good and Evil, Taylor looks for a more meaningful conception by reexamining and rejecting the whole rationalistic tradition that dominates philosophical ethics. The second part provides an empirical explanation of good and evil, noting that one does not have to look too far to find prime examples of the failure of fixed moral rules. Including important commentary on Joseph Fletcher's groundbreaking situation ethics, and Aristotle's virtues (e.g., magnanimity and pride), Taylor rounds out the book by developing a philosophy of aspiration--personal worth as an ethical ideal--to replace the morality of duty. He offers a modified form of situation ethics to fit the contemporary problems we face. (shrink)

Orientalism and Religion offers us a timely discussion of the implications of contemporary post-colonial theory for the study of religion. Drawing on a variety of post-structuralist and post-colonial thinkers, including Foucault, Gadamer, Said, and Spivak, Richard King examines the way in which notions such as mysticism, religion, Hinduism and Buddhism are taken for granted, and shows us how religion needs to be redescribed along the lines of cultural studies.

This is the third edition of a classic book first published in 1960, which has sold thousands of copies in two paperback edition and has been translated into several foreign languages. Popkin's work ha generated innumerable citations, and remains a valuable stimulus to current historical research.

According to certain normative theories in epistemology, rationality requires us to be logically omniscient. Yet this prescription clashes with our ordinary judgments of rationality. How should we resolve this tension? In this paper, I focus particularly on the logical omniscience requirement in Bayesian epistemology. Building on a key insight by Hacking :311–325, 1967), I develop a version of Bayesianism that permits logical ignorance. This includes: an account of the synchronic norms that govern a logically ignorant individual at any given time; (...) an account of how we reduce our logical ignorance by learning logical facts and how we should update our credences in response to such evidence; and an account of when logical ignorance is irrational and when it isn’t. At the end, I explain why the requirement of logical omniscience remains true of ideal agents with no computational, processing, or storage limitations. (shrink)

The book begins with an overview that introduces the Theorem and the issues surrounding it, and explores how the essays that follow contribute to our understanding of those issues.

Conditionalization is one of the central norms of Bayesian epistemology. But there are a number of competing formulations, and a number of arguments that purport to establish it. In this paper, I explore which formulations of the norm are supported by which arguments. In their standard formulations, each of the arguments I consider here depends on the same assumption, which I call Deterministic Updating. I will investigate whether it is possible to amend these arguments so that they no longer depend (...) on it. As I show, whether this is possible depends on the formulation of the norm under consideration. (shrink)

The Desire-as-Belief thesis (DAB) states that any rational person desires a proposition exactly to the degree that she believes or expects the proposition to be good. Many people take David Lewis to have shown the thesis to be inconsistent with Bayesian decision theory. However, as we show, Lewis's argument was based on an Invariance condition that itself is inconsistent with the (standard formulation of the) version of Bayesian decision theory that he assumed in his arguments against DAB. The aim of (...) this paper is to explore what impact the rejection of Invariance has on the DAB thesis. Without assuming Invariance, we first refute all versions of DAB that entail that there are only two levels of goodness. We next consider two theses according to which rational desires are intimately connected to expectations of (multi-levelled) goodness, and show that these are consistent with Bayesian decision theory as long as we assume that the contents of 'value propositions' are not fixed. We explain why this conclusion is independently plausible, and show how to construct such propositions. (shrink)
