This article focuses on the occasional individuals of many species that live longer than is usual for their populations – here called longevity outliers. They appear to be exceptions to the usual patterns of mortality rates that increase with age. There is no model of survivorship that accommodates all of these individuals. They are less vulnerable to the usual causes of death than most in their populations. There are hints of genetically based mechanisms in the form of life‐prolonging genes in (...) invertebrates and genetic resistance to fatal diseases in higher organisms. The reasons why longevity outliers ultimately die are not known. Based on well‐established trends, I predict that there will be many more humans reaching very old ages in the next century. (shrink)

Previous research has yielded inconsistent findings concerning the relationship between envy and schadenfreude. Three studies examined whether the distinction between benign and malicious envy can resolve this inconsistency. We found that malicious envy is related to schadenfreude, while benign envy is not. This result held both in the Netherlands where benign and malicious envy are indicated by separate words (Study 1: Sample A, N = 139; Sample B, N = 150), and in the USA where a single word is used (...) to denote both types (Study 2, N = 180; Study 3, N = 349). Moreover, the effect of malicious envy on schadenfreude was independent of other antecedents of schadenfreude (such as feelings of inferiority, disliking the target person, anger, and perceived deservedness). These findings improve our understanding of the antecedents of schadenfreude and help reconcile seemingly contradictory findings on the relationship between envy and schadenfreude. (shrink)

Before dealing directly with the content of Urban's thought, there remains to be singled out one of its general traits, a grasp of which is absolutely necessary for any understanding of his thought. From the beginning, Urban's philosophy has exhibited a refusal to accept any ultimate impasse in thought. His is the understanding or irenic type of view over against the one-sided or polemic type. For him, reason is always comprehensive enough to sustain differences of opinion, and it is able, (...) if one goes deeply enough, to show the relativity of all exclusive oppositions in philosophical thought. There is an almost Hegelian passion for synthesis in his dogged attempts to get beyond certain disagreements between philosophical positions. It was his wont to regard impasses in thought as futile in the precise sense that neither side is able to refute the other simply because there is a sense in which both are right and both are wrong. Many illustrations from the writings of what might be called this "transcending" approach can be given: in History he seeks to show the two-fold nature of sufficient reason as both logical and ontological and approves of Kant's attempt to establish a mediating position beyond both; in Valuation the attempt is made to get "beyond the dichotomy of 'appreciation' and 'description' "; in Intelligible the view is taken that logical values are neither "existent" nor "subsistent" but "simply valid" which view is said to be beyond special ontological prejudices; in Humanity Urban is concerned to show that the religious tradition of the West has been beyond the ultimate antithesis of pure deity or mere humanity and that an indissoluble relation between the two has always been acknowledged and accepted; the attempt to get "beyond" occupies, of course, the whole of Beyond, and need not be singled out for special attention at this juncture. These illustrations are only a few of many; in calling attention to this general trait, however, it must not be thought that anything more is intended than the emphasizing of a singularly important feature of Urban's thought. Such a trait, howsoever clearly understood, would still leave us far from an adequate comprehension of his idealism; but without taking it into account his views will often appear to lack sharpness and conviction. All that can be said is that these are some of the disadvantages of a harmonizing or transcending position. (shrink)

We report specific heat and μSR measurements on Th and/or B substituted UBe13. The specific heat data show that either Th or B substitution reduces the Kondo temperature TK and increases the entropy at the superconducting transition by almost 20%, indicating an enhanced density of states. However, whereas μSR shows clear evidence for magnetic correlations for Th substitutions, no magnetism is observed for B substitutions. The enhanced specific heat jump in the B-substituted material is associated with a change in the (...) superconducting properties as TK is reduced. (shrink)

This paper proposes a generalization of the Kripke semantics of intuitionistic logic IL appropriate for intuitionistic Łukasiewicz logic IŁL — a logic in the intersection between IL and (classical) Łukasiewicz logic. This generalised Kripke semantics is based on the poset sum construction, used in Bova and Montagna (Theoret Comput Sci 410(12):1143–1158, 2009) to show the decidability (and PSPACE completeness) of the quasiequational theory of commutative, integral and bounded GBL algebras. The main idea is that w \Vdash \sigma—which for IL is (...) a relation between worlds w and formulas \sigma, and can be seen as a function taking values in the booleans w \Vdash \sigma \in {B}—becomes a function taking values in the unit interval w \Vdash \sigma \in [0,1]. An appropriate monotonicity restriction (which we call sloping functions) needs to be put on such functions in order to ensure soundness and completeness of the semantics. (shrink)

People have always been xenophobic, but an explicit philosophical and scientific view of human racial difference only began to emerge during the modern period. Why and how did this happen? Surveying a range of philosophical and natural-scientific texts, dating from the Spanish Renaissance to the German Enlightenment, Nature, Human Nature, and Human Difference charts the evolution of the modern concept of race and shows that natural philosophy, particularly efforts to taxonomize and to order nature, played a crucial role. Smith (...) demonstrates how the denial of moral equality between Europeans and non-Europeans resulted from converging philosophical and scientific developments, including a declining belief in human nature's universality and the rise of biological classification. The racial typing of human beings grew from the need to understand humanity within an all-encompassing system of nature, alongside plants, minerals, primates, and other animals. While racial difference as seen through science did not arise in order to justify the enslavement of people, it became a rationalization and buttress for the practices of trans-Atlantic slavery. From the work of François Bernier to G. W. Leibniz, Immanuel Kant, and others, Smith delves into philosophy's part in the legacy and damages of modern racism. With a broad narrative stretching over two centuries, Nature, Human Nature, and Human Difference takes a critical historical look at how the racial categories that we divide ourselves into came into being.

What determines whether an action is right or wrong? Morality, Rules, and Consequences: A Critical Reader explores for students and researchers the relationship between consequentialist theory and moral rules. Most of the chapters focus on rule consequentialism or on the distinction between act and rule versions of consequentialism. Contributors, among them the leading philosophers in the discipline, suggest ways of assessing whether rule consequentialism could be a satisfactory moral theory. These essays, all of which are previously unpublished, provide students in (...) moral philosophy with essential material and ask key questions on just what the criteria for an adequate moral theory might be.

Though it did not yet exist as a discrete field of scientific inquiry, biology was at the heart of many of the most important debates in seventeenth-century philosophy. Nowhere is this more apparent than in the work of G. W. Leibniz. In Divine Machines, Justin Smith offers the first in-depth examination of Leibniz's deep and complex engagement with the empirical life sciences of his day, in areas as diverse as medicine, physiology, taxonomy, generation theory, and paleontology. He shows how (...) these wide-ranging pursuits were not only central to Leibniz's philosophical interests, but often provided the insights that led to some of his best-known philosophical doctrines.Presenting the clearest picture yet of the scope of Leibniz's theoretical interest in the life sciences, Divine Machines takes seriously the philosopher's own repeated claims that the world must be understood in fundamentally biological terms. Here Smith reveals a thinker who was immersed in the sciences of life, and looked to the living world for answers to vexing metaphysical problems. He casts Leibniz's philosophy in an entirely new light, demonstrating how it radically departed from the prevailing models of mechanical philosophy and had an enduring influence on the history and development of the life sciences. Along the way, Smith provides a fascinating glimpse into early modern debates about the nature and origins of organic life, and into how philosophers such as Leibniz engaged with the scientific dilemmas of their era.

Although much evidence indicates that young infants perceive unitary objects by analyzing patterns of motion, infantsÕ abilities to perceive object unity by analyzing Gestalt properties and by integrating distinct views of an object over time are in dispute. To address these controversies, four experiments investigated adultsÕ and infantsÕ perception of the unity of a center-occluded, moving rod with misaligned visible edges. Both alignment information and depth information affected adultsÕ and infantsÕ perception of object unity in similar ways, and infants perceived (...) object unity by integrating information about object features over time. However, infants perceived a moving, misaligned, three-dimensional object as indeterminate in its connectedness, whereas adults perceived it as connected behind the occluder. These findings indicate that the effectiveness of common motion in specifying unified surfaces across an occluder is reduced by misalignment of edges. Alignment information enhances perception of object unity either by serving directly as information for unity or by optimizing the detectability of motion-carried information for unity. In addition, young infants are able to retain information about edge orientation over short intervals in determining connectedness via a process of spatiotemporal integration.

An interpretative introduction to the major themes of classic American philosophy and five of its major figures: Peirce, James, Royce, Dewey and Whitehead. Smith shows sympathy and insight into these men and their ideas, making an excellent choice of basic themes for discussion. Running throughout the book is a sustained argument for a renewal of the breadth of philosophic interest and the sound empirical basis displayed by Pragmatism at its best. Smith is concerned that this "Spirit of American (...) Philosophy" be rescued from the neglect it has suffered over the past decades and be recalled to the attention of the philosophic community. His book is an admirable step in that direction.--W. G. E. (shrink)
