Sex- and age-specific rates of killing unrelated persons of one’s own sex were computed for Canada (1974–1983), England/Wales (1977–1986), Chicago (1965–1981), and Detroit (1972) from census information and data archives of all homicides known to police. Patterns in relation to sex and age were virtually identical among the four samples, although the rates varied enormously (from 3.7 per million citizens per annum in England/Wales to 216.3 in Detroit). Men’s marital status was related to the probability of committing a same-sex, nonrelative (...) homicide, but age effects remained conspicuous when married and unmarried men were distinguished.These findings and the treatment of age and sex effects by criminologists are discussed in the light of contemporary evolutionary psychological models of sex differences and life-span development. Same-sex homicides in which killer and victim are unrelated can be interpreted as an assay of competitive conflict. In every human society for which relevant information exists, men kill one another vastly more often than do women. Lethal interpersonal competition is especially prevalent among young men, which accords with many other aspects of life-span development in suggesting that sexual selection has maximized male competitive prowess and inclination in young adulthood.

The relationship between feminism and the biological sciences has always been particularly tense and hostile. Feminists have been inclined not to trust what scientists had to say about the sexes, with science often being pronounced a “white, male enterprise.” But why should feminism and the biological sciences remain at odds? And what might be gained from a reconciliation? In Who's Afraid of Charles Darwin? Griet Vandermassen shows that, rather than continuing this enmity, feminism and the biological sciences, and in particular (...) evolutionary psychology, have the potential and the need to become powerful allies. Properly understood, the Darwinian perspective proposed in this volume will become essential to tackling the major issues in feminism. (shrink)

An evolutionary psychological perspective drawing on sexual selection theory can better explain sex differences in aggression and violence than can social constructionist theories. Moreover, there is accumulating evidence that, in accordance with predictions derived from sexual selection theory, men modulate their willingness to engage in risky and violent confrontations in response to cues to fitness variance and future prospects.

Henrich et al.'s nice cross-cultural experiments would benefit from models that specify the decision rules that humans use and the specific developmental pathways that allow cooperative norms to be internalized. Such models could help researchers to design further experiments to examine human social adaptations. We must also test whether the “same” experiments measure similar constructs in each culture, using additional methods and measures.

The distinction between clinical practice and surgical research may seem trivial, but this distinction can become a complex issue when innovative surgeries are substituted for standard care without patient knowledge. Neither the novelty nor the risk of a new surgical procedure adequately defines surgical research. Some institutions tacitly allow the use of new surgical procedures in series of patients without informing individuals that they are participating in a scientific study, as long as no written protocol or hypothesis exists. Institutions can (...) justify this practice by viewing human research in narrow terms as an activity outlined in a formal protocol. Application of limited definitions, however, erodes patients' rights and risks losing public confidence in how biomedical research is conducted. I propose an operational definition of human research also be recognised. Enforcing more rigid and less ambiguous guidelines of human research may curtail enrolment into some studies, but it will also protect patients from being used as subjects without their knowledge.

Considering that much of human society is structured through its interaction with non-human animals, and since human society relies heavily on the exploitation of animals to serve human needs, human-animal studies has become a rapidly expanding field of research, featuring a number of distinct positions, perspectives, and theories that require nuanced explanation and contextualization. The first book to provide a full overview of human-animal studies, this volume focuses on the conceptual construction of animals in American culture and the way in (...) which it reinforces and perpetuates hierarchical human relationships rooted in racism, sexism, and class privilege. Margo DeMello considers interactions between humans and animals within the family, the law, the religious and political system, and other major social institutions, and she unpacks the different identities humans fashion for themselves and for others through animals. Essays also cover speciesism and evolutionary continuities; the role and preservation of animals in the wild; the debate over zoos and the use of animals in sports; domestication; agricultural practices such as factory farming; vivisection; animal cruelty; animal activism; the representation of animals in literature and film; and animal ethics. Sidebars highlight contemporary controversies and issues, with recommendations for additional reading, educational films, and related websites. DeMello concludes with an analysis of major philosophical positions on human social policy and the future of human-animal relations. (shrink)

Reach into the heart and soul of people from every inhabited continent through sixty tour de force black-and-white portraits by Margo Davis. Under One Sky is a collection of nearly forty years of portrait making by one of the inheritors of California’s photographic legacy. Esthetically powerful and convincing were words used by Ansel Adams in 1968 to describe the work of Davis and her fellow students. Indeed, the same words can be used today in describing these portraits. As Davis (...) says in her accompanying essay, “A portrait that has the power to truly look inward can shake us up and make us question our assumptions. Like the finest literature, a powerful photographic portrait permits us to leap into the other’s mind and heart.”. (shrink)

When people speak, their words never fully encode what they mean, and the context is always compatible with a variety of interpretations. How can comprehension ever be achieved? Wilson and Sperber argue that comprehension is an inference process guided by precise expectations of relevance. What are the relations between the linguistically encoded meanings studied in semantics and the thoughts that humans are capable of entertaining and conveying? How should we analyse literal meaning, approximations, metaphors and ironies? Is the ability (...) to understand speakers' meanings rooted in a more general human ability to understand other minds? How do these abilities interact in evolution and in cognitive development? MEANING AND RELEVANCE sets out to answer these and other questions, enriching and updating relevance theory and exploring its implications for linguistics, philosophy, cognitive science and literary studies.

Dietary restriction (DR) famously extends lifespan and reduces fecundity across a diverse range of species. A prominent hypothesis suggests that these life‐history responses evolved as a survival‐enhancing strategy whereby resources are redirected from reproduction to somatic maintenance, enabling organisms to weather periods of resource scarcity. We argue that this hypothesis is inconsistent with recent evidence and at odds with the ecology of natural populations. We consider a wealth of molecular, medical, and evolutionary research, and conclude that the lifespan extension effect (...) of DR is likely to be a laboratory artifact: in contrast with captivity, most animals living in natural environments may fail to achieve lifespan extension under DR. What, then, is the evolutionary significance of the suite of responses that extend lifespan in the laboratory? We suggest that these responses represent a highly conserved nutrient recycling mechanism that enables organisms to maximize immediate reproductive output under conditions of resource scarcity.

(Note: the posted version of this paper is undergoing non-trivial revision; an updated version will be posted in June 2024.) Is there a need for a distinctively diachronic conception of metaphysical emergence? Here I argue to the contrary. In the main, my strategy consists in considering a representative sample of accounts of purportedly diachronic metaphysical emergence, and arguing that in each case, the purportedly diachronic emergence at issue either can (and should) be subsumed under a broadly synchronic account of metaphysical (...) emergence, or else is better seen as simply a case of causation. In addition, I consider and argue against the suggestion that 'in-principle unpredictability' accounts of diachronic emergence support there being distinctively diachronic metaphysical emergence.

In his book Neoliberalism’s War on Higher Education, Henry Giroux bemoans, “[H]igher education increasingly stands alone, even in its attenuated state, as a public arena where ideas can be debated, critical knowledge produced, and learning linked to important social issues.”1 Colleges of education, like public schools themselves, have become more fragmented and compartmentalized in recent years. Persistent at universities is “the view that students are basically consumers and faculty providers of a saleable commodity such as a credential or a set (...) of workplace skills.”2 Professors and teachers alike feel the impact of neoliberal policies aimed at efficiency and productivity, which further alienate and emphasize data...

Many or almost all writers about truth seem to agree that the entailment by a more or less formal account of truth of all the instances of the so-called disquotational schema - (DQ) <p> is true if and only if p - is at least a necessary condition for this account to count as an adequate account of truth. My first task in this paper is to show that the correctness of the observation (DQ) does not by itself imply that (...) truth lacks substance. My second task is to establish the instances of (DQ) as not only necessary but also sufficient for a characterisation of truth. Such a minimal theory of truth would seem to rob truth of all substance but going in for a more eloquent alternative as I shall attempt to show could result in an unwanted epistemisation of truth.

How should physical entities be characterized? Physicalists, who have most to do with the notion, usually characterize the physical by reference to two components: 1. The physical entities are the entities treated by fundamental physics with the proviso that 2. Physical entities are not fundamentally mental (that is, do not individually possess or bestow mentality) Here I explore the extent to which the appeals to fundamental physics and to the NFM (“no fundamental mentality”) constraint are appropriate for characterizing the physical, (...) especially for purposes of formulating physicalism. Ultimately, I motivate and defend a version of an account incorporating both components: The physics-based NFM account: An entity existing at a world w is physical iff (i) it is treated, approximately accurately, by current or future (in the limit of inquiry, ideal) versions of fundamental physics at w, and (ii) it is not fundamentally mental (that is, does not individually either possess or bestow mentality).

This article explores three ways in which physics may involve counterpossible reasoning. The first way arises when evaluating false theories: to say what the world would be like if the theory were true, we need to evaluate counterfactuals with physically impossible antecedents. The second way relates to the role of counterfactuals in characterizing causal structure: to say what causes what in physics, we need to make reference to physically impossible scenarios. The third way is novel: to model metaphysical dependence in (...) physics, we need to consider counterfactual consequences of metaphysical impossibilities. Physics accordingly bears substantial and surprising counterpossible commitments. (shrink)

How are non-declarative sentences understood? How do they differ semantically from their declarative counterparts? Answers to these questions once made direct appeal to the notion of illocutionary force. When they proved unsatisfactory, the fault was diagnosed as a failure to distinguish properly between mood and force. For some years now, efforts have been under way to develop a satisfactory account of the semantics of mood. In this paper, we consider the current achievements and future prospects of the mood-based semantic programme.

This paper offers an overview of "the species problem", arguing for a view of species as homeostatic property cluster kinds, positioning the resulting form of realism about species as an alternative to the claim that species are individuals and pluralistic views of species. It draws on taxonomic practice in the neurosciences, especially of neural crest cells and retinal ganglion cells, to motivate both the rejection of the species-as-individuals thesis and species pluralism.

Let us begin with the simple observation that applied mathematics can be very tough! It is a common occurrence that basic physical principle instructs us to construct some syntactically simple set of differential equations, but it then proves almost impossible to extract salient information from them. As Charles Peirce once remarked, you can’t get a set of such equations to divulge their secrets by simply tilting at them like Don Quixote. As a consequence, applied mathematicians are often forced to pursue (...) roundabout and shakily rationalized expedients if any useful progress is to be made. Often these provisional and quasi-empirical procedures within applied mathematics loom large in motivating the “anti-realist” or “anti-unificationist” conclusions of Nancy Cartwright and allied authors.

In this article I will argue that there are two theories of distributive justice hidden in Walzer's Spheres of Justice. The first one emphasises the separation of distributive spheres. It tries to formulate distributive criteria by sticking faithfully to sphere‐specificity. I shall refer to this theory as ‘pure pluralism’. The second theory downplays the separation of spheres and emphasises ‘across spheres’ or ‘between spheres’ criteria instead. I shall call this theory ‘mitigated pluralism’. Mitigated pluralism has become popular among Walzer's friendly (...) critics who apparently do not want to charge him with a distributive theory as clear and rigid as pure pluralism. Although I consider myself another friendly critic, I shall argue in favour of pure pluralism. (shrink)

The Making of British Bioethics provides the first in-depth study of how philosophers, lawyers and other 'outsiders' came to play a major role in discussing and helping to regulate issues that used to be left to doctors and scientists. It details how British bioethics emerged thanks to a dynamic interplay between sociopolitical concerns and the aims of specific professional groups and individuals who helped create the demand for outside involvement and transformed themselves into influential 'ethics experts'. Highlighting this interplay helps (...) us appreciate how issues such as embryo research and assisted dying became high-profile 'bioethical' concerns in the late twentieth century, and why different groups now play a critical role in developing regulatory standards and leading public debates. The book draws on a wide range of original sources and will be of interest to historians of medicine and science, general historians and bioethicists. (shrink)

Everyone loves something or somebody, and most people are concerned with loving another person like themselves, all equal. This book is based on the belief that getting clear about the concept and meaning of love between equals is essential for success in our practical lives. For how can we love properly unless we have a fairly clear idea of what love is? The book is written in ordinary language and for the ordinary person, without jargon or philosophical technicalities. It aims (...) to show that love between equals involves a single basic disposition, though that disposition expresses itself in various ways. Thus, after an introduction explaining the need for analysis and clarification, the author then deals in order with love as desire or need; with intrinsic friendship and sharing the self; with basic difficulties concerning power, dependence, altruism and paranoia; with sex and erotic love; and finally with the value in human life of love between equals. The work as a whole gives clear, coherent and practical guidance for all who wish to grasp what such love is really like. (shrink)

This landmark study examines the role played by the rediscovery of the writings of the ancient atomists, Epicurus and Lucretius, in the articulation of the major philosophical systems of the seventeenth century, and, more broadly, their influence on the evolution of natural science and moral and political philosophy. The target of sustained and trenchant philosophical criticism by Cicero, and of opprobrium by the Christian Fathers of the early Church, for its unflinching commitment to the absence of divine supervision and the (...) finitude of life, the Epicurean philosophy surfaced again in the period of the Scientific Revolution, when it displaced scholastic Aristotelianism. Both modern social contract theory and utilitarianism in ethics were grounded in its tenets. Catherine Wilson shows how the distinctive Epicurean image of the natural and social worlds took hold in philosophy, and how it is an acknowledged, and often unacknowledged presence in the writings of Descartes, Gassendi, Hobbes, Boyle, Locke, Leibniz, Berkeley. With chapters devoted to Epicurean physics and cosmology, the corpuscularian or "mechanical" philosophy, the question of the mortality of the soul, the grounds of political authority, the contested nature of the experimental philosophy, sensuality, curiosity, and the role of pleasure and utility in ethics, the author makes a persuasive case for the significance of materialism in seventeenth-century philosophy without underestimating the depth and significance of the opposition to it, and for its continued importance in the contemporary world. Lucretius's great poem, On the Nature of Things, supplies the frame of reference for this deeply-researched inquiry into the origins of modern philosophy. (shrink)

In his preface Mr Wilson writes 'I feel that a great many adults … would do better to spend less time in simply accepting the concepts of others uncritically, and more time in learning how to analyse concepts in general'. Mr Wilson starts by describing the techniques of conceptual analysis. He then gives examples of them in action by composing answers to specific questions and by criticism of quoted passages of argument. Chapter 3 sums up the importance of (...) this kind of mental activity. Chapter 4 presents selections for the reader to analyse, followed by questions of university entrance/scholarship type. This is a book to be worked through, in a sense a text-book. (shrink)

The infant mortality rate in Liberia is 50 times higher than it is in Sweden, whilst a child born in Japan has a life expectancy at birth of more than double that of one born in Zambia. 1 And within countries, we see differences which are nearly as great. For example, if you were in the USA and travelled the short journey from the poorer parts of Washington to Montgomery County Maryland, you would find that ‘for each mile travelled life (...) expectancy rises about a year and a half. There is a twenty-year gap between poor blacks at one end of the journey and rich whites at the other’. (Marmot, 2004, p.2). There are two types of questions which it is important to ask about inequalities in health such as these. The first are social scientific questions about the extent of inequalities in health and the factors which are causally responsible for these inequalities. Examples of social scientific questions to ask might be: how do infant mortality rates in the UK differ according to social class? What is the difference in life expectancy between Japanese who emigrate to the US and those who remain in Japan? Why do civil servants in higher ranked jobs tend to live longer than civil servants in lower ranked jobs? The second type are normative questions about the reasons we have to care about inequalities in health. Important normative questions to answer are: which inequalities in health should we care about (all inequalities or merely some of them)? When is an inequality in health unjust? How should we weigh our concern for equality in health against other factors such as maximising the.. (shrink)

National Book Award Finalist. How did humanity originate and why does a species like ours exist on this planet? Do we have a special place, even a destiny in the universe? Where are we going, and perhaps, the most difficult question of all, "Why?" In The Meaning of Human Existence, his most philosophical work to date, Pulitzer Prize–winning biologist Edward O. Wilson grapples with these and other existential questions, examining what makes human beings supremely different from all other species. (...) Searching for meaning in what Nietzsche once called "the rainbow colors" around the outer edges of knowledge and imagination, Wilson takes his readers on a journey, in the process bridging science and philosophy to create a twenty-first-century treatise on human existence—from our earliest inception to a provocative look at what the future of mankind portends. Continuing his groundbreaking examination of our "Anthropocene Epoch," which he began with The Social Conquest of Earth, described by the New York Times as "a sweeping account of the human rise to domination of the biosphere," here Wilson posits that we, as a species, now know enough about the universe and ourselves that we can begin to approach questions about our place in the cosmos and the meaning of intelligent life in a systematic, indeed, in a testable way. Once criticized for a purely mechanistic view of human life and an overreliance on genetic predetermination, Wilson presents in The Meaning of Human Existence his most expansive and advanced theories on the sovereignty of human life, recognizing that, even though the human and the spider evolved similarly, the poet's sonnet is wholly different from the spider's web. Whether attempting to explicate "The Riddle of the Human Species," "Free Will," or "Religion"; warning of "The Collapse of Biodiversity"; or even creating a plausible "Portrait of E.T.," Wilson does indeed believe that humanity holds a special position in the known universe. The human epoch that began in biological evolution and passed into pre-, then recorded, history is now more than ever before in our hands. Yet alarmed that we are about to abandon natural selection by redesigning biology and human nature as we wish them, Wilson soberly concludes that advances in science and technology bring us our greatest moral dilemma since God stayed the hand of Abraham.
