Ambos-Spies, K. and R.A. Shore, Undecidability and 1-types in the recursively enumerable degrees, Annals of Pure and Applied Logic 63 3–37. We show that the theory of the partial ordering of recursively enumerable Turing degrees is undecidable and has uncountably many 1-types. In contrast to the original proof of the former which used a very complicated O''' argument our proof proceeds by a much simpler infinite injury argument. Moreover, it combines with the permitting technique to get similar results for any (...) ideal of the r.e. degrees. (shrink)

Science, the Singular, and the Question of Theology explores the role that the singular plays in the theories of science of Robert Grosseteste, Thomas Aquinas, Duns Scotus, William of Ockham, Marsilius of Inghen, and Pierre d'Ailly. It pursues the question specifically in relation to the question of whether theology is a science. The work argues that the main issue in debates concerns whether theology is a science and how to provide a 'rational ground' for existing singulars. Science, the Singular, and (...) the Question of Theology exposes how, on the eve of modernity, existing singulars were freed from the constraints of rational ground. (shrink)

Solving the 4-d Einstein equations as evolution in time requires solving equations of two types: the four elliptic initial data (constraint) equations, followed by the six second-order evolution equations. Analytically the constraint equations remain solved under the action of the evolution, and one approach is to simply monitor them (unconstrained evolution). The problem of the 3-d computational simulation of even a single isolated vacuum black hole has proven to be remarkably difficult. Recently, we have become aware of two publications that (...) describe very long term evolution, at least for single isolated black holes. An essential feature in each of these results is constraint subtraction. Additionally, each of these approaches is based on what we call “modern,” hyperbolic formulations of the Einstein equations. It is generally assumed, based on computational experience, that the use of such modern formulations is essential for long-term black hole stability. We report here on comparable lifetime results based on the much simpler (“traditional”) ${\dot g} - {\dot K}$ formulation. With specific subtraction of constraints, with a simple analytic gauge, with very simple boundary conditions, and for moderately large domains with moderately fine resolution, we find computational evolutions of isolated non-spinning black holes for times exceeding 1000 GM/c2. We have also carried out a series of constrained 3-d evolutions of single isolated black holes. We find that constraint solution can produce substantially stabilized long-term single hole evolutions. However, we have found that for large domains, neither constraint-subtracted nor constrained ${\dot g} - {\dot K}$ evolutions carried out in Cartesian coordinates admit arbitrarily long-lived simulations. The failure appears to arise from features at the inner excision boundary; the behavior does generally improve with resolution. (shrink)

Although often neglected, An Examination of the Philosophy of Bacon is crucial to understand the epistemological basis for Maistre's critique of modern science as well as his criticisms of other aspects of Enlightenment thought. Given Maistre's stature in the history of conservative thought, his critique of Bacon remains significant for what it tells us about Maistre's own thought, what it reveals about attitudes toward science in his time, and what it contributes to issues that are still debated today. The work (...) also showcases Maistre's polemical skills and his powerful prose style. Richard Lebrun's annotated translation includes Maistre's complete text, an extensive introduction that places the work in context and provides a critical exposition and assessment of Maistre's criticisms of Bacon, biographical notes on persons cited or mentioned by Maistre, and a bibliography. Differences between Maistre's manuscript and the printed text, first published fifteen years after the author's death, are noted, and Maistre's numerous citations have been identified, verified, and translated, making this the only authoritative and fully accurate edition of the work in either French or English.

There is long-standing disagreement among systematists about how to divide biodiversity into species. Over twenty different species concepts are used to group organisms, according to criteria as diverse as morphological or molecular similarity, interbreeding and genealogical relationships. This, combined with the implications of evolutionary biology, raises the worry that either there is no single kind of species, or that species are not real. This book surveys the history of thinking about species from Aristotle to modern systematics in order to understand (...) the origin of the problem, and advocates a solution based on the idea of the division of conceptual labor, whereby species concepts function in different ways - theoretically and operationally. It also considers related topics such as individuality and the metaphysics of evolution, and how scientific terms get their meaning. This important addition to the current debate will be essential for philosophers and historians of science, and for biologists. (shrink)

My heart was removed and replaced on May 17, 2006. No melodrama is intended here, just an unadorned factual statement. Transplants are transformative. In my case, that transformation led to bioethics.

Modern biological classification is based on the system developed by Linnaeus, and interpreted by Darwin as representing the tree of life. But despite its widespread acceptance, the evolutionary interpretation has some problems and limitations. This comprehensive book provides a single resource for understanding all the main philosophical issues and controversies about biological classification. It surveys the history of biological classification from Aristotle to contemporary phylogenetics and shows how modern biological classification has developed and changed over time. Readers will also be (...) able to see how biological classification is in part a consequence of human psychology, language development and culture. The book will be valuable for student readers and others interested in a range of topics in philosophy and biology. (shrink)

The country's leading libertarian scholar sets forth the essential principles for a legal system that best balances individual liberty versus the common good.

The Internet presents opportunities for corporations to efficiently build their brands online and to enhance their global reach. But there are threats as well as opportunities, since anti-branding and free-riding activities are easier in cyberspace. One such threat is theunauthorized incorporation of a trademark into a domain name. This can lead to trademark dilution and cause consumer confusion. But some users claim a right to use these trademarks for the purpose of parody or criticism. Underlying these trademark conflicts is the (...) familiar tension between property rights and free speech rights. While some trademark scholars are reluctant to consider a trademark as property, we find strong support for the property paradigm in Hegel’s philosophy. Assuming that a trademark is an earned property right, we propose that a trademark owner should be allowed to control the permutations of its trademark incorporated into domain names unless a reasonable person would not confuse that domain name with the company’s mark. But we also conclude that there must be latitude to employ a domain name for negative editorial comment, so long as the source and purpose of that domain name is plainly apparent. (shrink)

Stimulated by these three brilliant target essays this commentary raises a few questions about the universality of the “emotions,” the cultural psychology of “natural kinds,” and the analytic deconstruction of the idea of an emotion.

This commentary on four theoretical articles published in this issue of Emotion Review discusses the one big thing that links them all and raises some questions about the ontological status of the appraisal part of appraisal theories of emotion.

For many adolescent Kenyan males genital reshaping is a self-defining experience of enormous positive significance. The same can be said for many Kenyan females. These adolescents, male and female, do not think their bodies have been “mutilated.” Quite the contrary, by their lights the surgical procedure removes a defect of nature and is the means by which a desired state of physical integrity and social maturity is achieved. By their lights the procedure gets rid of unseemly fleshy encumbrances and protrusions (...) and helps them erase unwanted physical traces of childhood bisexuality, thereby making their genitals look smooth and clean and more gender appropriate. By their lights their appearance and... (shrink)

Imitation is said to be the sincerest form of flattery. Socially, the proposition may well be true. But in the world of ideas it is false: to the extent that two incompatible traditions use the same words or symbols to articulate different visions of legal or social organization, imitation begets confusion, not enlightenment. The effects of that confusion, moreover, are not confined to the world of ideas, but spill over into the world of politics and public affairs. Words are more (...) than tools of description: they work also as tools of persuasion and transformation. Let a term have a favorable connotation in one context, and its imitative use can mislead people into thinking that a major departure from established practice is merely the extension or updating of an old principle to deal with new circumstances.

'Tis true governments cannot be supported without great charge, and it is fit everyone who enjoys a share of the protection should pay out of his estate his proportion for the maintenance of it.

The RIAA v. Verizon case offers an opportunity to analyze the scope of an Internet service provider’s responsibility to help deter copyright infringement. In this case, the RIAA served Verizon with a subpoena requesting the identity of two users who were making available copyrighted recordings for downloading on peer‐to‐peer networks. The main axis of discussion is whether or not Verizon has a moral obligation to reveal the names of these individuals. Should Verizon cooperate with the RIAA or should it seek (...) to shield the identity of these users in order to protect their anonymity and privacy? A secondary theme concerns Verizon’s prospective responsibility to curtail infringement. We will argue that Verizon and other ISPs have a limited obligation to assist copyright holders by disclosing the identity of infringers, but we contend that any prospective responsibility is constrained by law and technological capability.

The founder of American pragmatism, C.S. Peirce, lived as an eccentric, but thought as a dedicated communitarian. In Reading Peirce Reading, Richard Smyth demonstrates that Peirce's early essays presuppose a very distinctive perspective on the history of philosophy. One important mark of a major philosopher, Smyth argues, is that the philosopher causes us to read the history of thought in new ways. Smyth shows not only that Peirce passes that test, but that Peirce's philosophical practice actually did conform to (...) his communal ideal for inquiry. Students and scholars interested in the history of philosophy and pragmatism will want to read this book. (shrink)

Ame Naess, John Rodman, George Sessions, and others, designated herein as ecosophers, propose an egalitarian anti-anthropocentric biocentrism as a basis for a new environmental ethic. I outline their “hands-off-nature” position and show it to be based on setting man apart. The ecosophic position is thus neither egalitarian nor fully biocentric. A fully egalitarian biocentric ethic would place no more restrictions on the behavior of human beings than on the behavior of any other animals. Uncontrolled human behavior might lead to the (...) destruction ofthe environment and thus to the extinction of human beings. I thus conclude that human interest in survival is the best ground on which to argue for an ecological balance which is good both for human beings and for the whole biological community. (shrink)

In the aftermath of the events of September 11, 2001, Stanley Katz (who now chairs the editorial board of this journal) invited the intellectual community to reflect on its own history of involvement in public affairs and to make good on its mistakes. This essay examines a single case of intellectuals involving themselves in public affairs and some of the difficulties in saying and evaluating exactly what happened. Critical attention is given to Anthropological Intelligence, a book by David Price published (...) in 2008, which concerns the involvement of anthropologists in wartime activities during World War II and argues that even that “just war” left an indelible stain on the moral fabric of the discipline.

Over two hundred years ago, Thomas Jefferson suggested the need for a broader legal curriculum. As the twenty-first century begins, the practice of law will increasingly demand interdisciplinary knowledge and collaboration — between those trained in law and a broad range of scientific and technical fields, including engineering, biology, genetics, ethics, and the social sciences. The practice of public health law provides a model for both the substantive integration of law with science, and for the way its practitioners work. In (...) addition, public health law also provides a model for interdisciphuy and integrative teaching. (shrink)

A dozen papers by internationally known scholars explore questions largely unthinkable without Richard Watson's classic Downfall of Cartesianism: Descartes in Holland, Descartes and Simon Foucher, and issues raised by Descartes for philosophy of mind, philosophy of science, translation and toleration.

In this paper, I want to explore the relationship between the various forms of individual self-interest and the appropriate structures of government. I shall begin with the former, and by degrees extend the analysis to the latter. I do so in order to mount a defense of principles of limited government, private property, and individual liberty. The ordinary analysis of self-interest treats it as though it were not only a given but also a constant of human nature, and thus makes (...) few allowances for differences between persons. Yet common experience tells us that personality and behavior are as unique as fingerprints. The positive inquiry, therefore, is how we find what is constant about self-interest in a world of natural human diversity. The normative inquiry must take into account both the constant and variable features of human nature in order to determine what forms of social arrangements hold the greatest prospect of long-term social advantage. The gulf between ‘is’ and ‘ought’ must be overcome here, as it must be in all normative discourse. Yet we cannot make sensible judgments of what ought to be the case in the domain of rules unless we first have some idea of what is the case in the domain of behavior. The initial inquiry asks why self-interest is regarded as a constant of human behavior. The explanation derives more from the biological and less from the social. The powerful pressures of natural selection weed out any organisms for whom selfinterest is not the paramount consideration. (shrink)

Detailed exposition of the nine layers of signification of human mortality according to Emmanuel Levinas's phenomenological and ethical account of the meaning and role of death for the embodied human subject and its relations to other persons. Critical contrast to Martin Heidegger's alternative and hitherto more influential phenomenological-ontological conception, elaborated in "Being and Time", of mortality as Dasein's anxious and revelatory being-toward-death.

The web creates manyopportunities for encroachment on intellectualproperty including trademarks. Our principaltask in this paper is an investigation into anunusual form of such encroachment: theimproper use of metatags. A metatag is a pieceof HTML code that provides summary informationabout a web page. If used in an appropriatemanner, these metatags can play a legitimaterole in helping consumers locate information. But the ``keyword'' metatag is particularlysusceptible to manipulation. These tags can beeasily abused by web site creators anxious tobait search engines and bring (...) scores ofvisitors to their sites. The law aboutmetatags is far from settled and many legalscholars are uncomfortable with the conclusionthat the unauthorized use of a trademark in ametatag represents infringement. How should weassess this practice known as ``spamdexing'' froma normative perspective? Is it commercial fairplay or something more sinister? We make thecase here that there are salient moral problemswith spamdexing since it exploits thereputational goodwill of trademark owners andconfuses consumers. It violates basic moralduties and it flouts the golden rule principle. Hence unauthorized use of a competitor'strademark in a metatag is not morallyacceptable. (shrink)

If X0and X1are both generic, the theories of the degrees below X0and X1are the same. The same is true if both are random. We show that then-genericity orn-randomness of X do not suffice to guarantee that the degrees below X have these common theories. We also show that these two theories are different. These results answer questions of Jockusch as well as Barmpalias, Day and Lewis.
