A serious yet unstudied consequence of the Christian-Muslim conflict in medieval Spain was the capture and enslavement of soldiers and civilians. Men, women, and children who were seized on raids, taken in battle, or pirated off ships were regarded by their captors as booty, to be used as slaves or to be sold for profit. Since warfare in twelfth-century Spain pitted Christians against Muslims, the usual prohibitions against enslavement of coreligionists clearly did not apply. For Muslims and Christians alike, capture (...) meant a life of slavery. Christian chronicles of this era are replete with stories of captives taken off to be sold in the slave markets of al-Andalus in southern Spain or, even worse, in those of North Africa. Some of these slaves, however, were able to regain their freedom through redemption — that is, to purchase their liberty by paying a ransom. Since the ransom price frequently exceeded what could be gained in the slave auctions, redemption became an attractive option to both captor and captive. (shrink)

RésuméLe but de cet article est de mettre en évidence les différences entre Descartes et Reid au sujet du rôle que chacun assigne aux sensations dans le processus perceptuel. Dans Perceptual Acquaintance, John Yolton ne trouve quepeu de choses dans les conceptions de Reid qui ne soient pas déjà de quelque façon présentes chez Descartes. Je soutiens au contraire que la théorie des sensations-comme-signes de Reid constitue un développement considérable par rapport à celle de Descartes ou à quoi que ce (...) soit que l'on trouve chez lui, non seulement parce qu'elle est évidemment plus claire et plus cohérente, mais aussi parce qu'elle introduit l'idée d'un élément a priori dans notre expérience perceptuelle et lui attribue un rôle indispensable. Cet élément crucial est tout à fait absent de la conception cartésienne. (shrink)

This fully revised and extended edition of James Nickel's classic study explains and defends the conception of human rights found in the Universal Declaration of Human Rights and subsequent human rights treaties. Combining philosophical, legal, and political approaches, Nickel addresses questions about what human rights are, what their content should be, and whether and how they can be justified.

The United States has never been culturally or religiously homogeneous, but its diversity has greatly increased over the last century. Although the U.S. was first a multicultural nation through conquest and enslavement, its present diversity is due equally to immigration. In this paper I try to explain the difference it makes for one area of thought and policy – equal opportunity – if we incorporate cultural and religious pluralism into our national self-image. Formulating and implementing a policy of equal opportunity (...) is more difficult in diverse, pluralistic countries than it is in homogeneous ones. My focus is cultural and religious diversity in the United States, but my conclusions will apply to many other countries – including ones whose pluralism is found more in religion than in culture.

The concept of hegemonic masculinity has influenced gender studies across many academic fields but has also attracted serious criticism. The authors trace the origin of the concept in a convergence of ideas in the early 1980s and map the ways it was applied when research on men and masculinities expanded. Evaluating the principal criticisms, the authors defend the underlying concept of masculinity, which in most research use is neither reified nor essentialist. However, the criticism of trait models of gender and (...) rigid typologies is sound. The treatment of the subject in research on hegemonic masculinity can be improved with the aid of recent psychological models, although limits to discursive flexibility must be recognized. The concept of hegemonic masculinity does not equate to a model of social reproduction; we need to recognize social struggles in which subordinated masculinities influence dominant forms. Finally, the authors review what has been confirmed from early formulations and what needs to be discarded. The authors suggest reformulation of the concept in four areas: a more complex model of gender hierarchy, emphasizing the agency of women; explicit recognition of the geography of masculinities, emphasizing the interplay among local, regional, and global levels; a more specific treatment of embodiment in contexts of privilege and power; and a stronger emphasis on the dynamics of hegemonic masculinity, recognizing internal contradictions and the possibilities of movement toward gender democracy.

Profit is a concept that both causes and manifests deep conflict and division. It is not merely that people disagree over whether it is good or bad. The very meaning of the concept and its role in competing theories necessitates the deepest possible disagreement; people cannot agree on what profit is. Still, simply learning the starkly different sentiments expressed about profit gives us some feel for the depth of the conflict. Friends of capitalism have praised profit as central to the (...) achievement of prosperity and to civilized modern life. Calvin Coolidge, that silent sentinel of American business, said, “Profit and civilization go hand in hand.” F. A. Hayek tells us that in the evolution of the structure of human activities, profitability works as a signal that guides selection towards what makes man more fruitful; only what is more profitable will, as a rule, nourish more people, for it sacrifices less than it adds.

At present, Third World countries owe over one trillion dollars to the developed Western nations; much of the debt is held by the leading international commercial banks. The debt of six Latin American countries alone — Argentina, Brazil, Chile, Mexico, Peru, and Venezuela — is over $330 billion, of which $240 billion is owed to commercial banks. Let us immediately narrow our focus to loans made by the major international commercial banks to Third World governments. We shall not be concerned (...) with government-to-government loans, or private-party-to-private-party loans, or with debt owed to the World Bank or the International Monetary Fund. The bank-to-government loans — the so-called “sovereign loans” — are the most economically troublesome and morally interesting. The largest lenders, at least with respect to the Latin American countries, are the American banks Citibank, Chase Manhattan, Bank of America, Manufacturers Hanover, and Chemical Bank. About fifteen Third World countries have serious debt problems, including the largest: Brazil, Mexico, and Argentina. (shrink)

What do the rules of logic say about the meanings of the symbols they govern? In this book, James W. Garson examines the inferential behaviour of logical connectives, whose behaviour is defined by strict rules, and proves definitive results concerning exactly what those rules express about connective truth conditions. He explores the ways in which, depending on circumstances, a system of rules may provide no interpretation of a connective at all, or the interpretation we ordinarily expect for it, or (...) an unfamiliar or novel interpretation. He also shows how the novel interpretations thus generated may be used to help analyse philosophical problems such as vagueness and the open future. His book will be valuable for graduates and specialists in logic, philosophy of logic, and philosophy of language. (shrink)

Given the recent ethics scandals in the United States, there has been a renewed focus on understanding the antecedents to ethical decision-making in the research literature. Since ethical norms and standards of behavior are not universally consistent, an individual’s choice of referent may exert a large influence on his/her ethical decision-making. This study used a social identity theory lens to empirically examine the relative influence of the macro- and micro-level variables of national culture and peers on an individual’s intention to (...) behave ethically. Our sample consisted of respondents from Germany, Italy, and Japan. The results indicated that both national culture and peers were found to act as significant referents in ethical decision-making dilemmas. Although peers exerted a much stronger influence on an individual’s ethical decision-making, the impact of peers varied depending on the national culture levels of individualism and power distance.

Designed for use by philosophy students, this 2006 book provides an accessible, yet technically sound treatment of modal logic and its philosophical applications. Every effort has been made to simplify the presentation by using diagrams in place of more complex mathematical apparatus. These and other innovations provide philosophers with easy access to a rich variety of topics in modal logic, including a full coverage of quantified modal logic, non-rigid designators, definite descriptions, and the de-re de-dictio distinction. Discussion of philosophical issues (...) concerning the development of modal logic is woven into the text. The book uses natural deduction systems and also includes a diagram technique that extends the method of truth trees to modal logic. This feature provides a foundation for a novel method for showing completeness, one that is easy to extend to systems that include quantifiers. (shrink)

Behavior genetics is a controversial science. For decades, scholars have sought to understand the role of heredity in human behavior and life-course outcomes. Recently, technological advances and the rapid expansion of genomic databases have facilitated the discovery of genes associated with human phenotypes such as educational attainment and substance use disorders. To maximize the potential of this flourishing science, and to minimize potential harms, careful analysis of what it would mean for genes to be causes of human behavior is needed. (...) In this paper, we advance a framework for identifying instances of genetic causes, interpreting those causal relationships, and applying them to advance causal knowledge more generally in the social sciences. Central to thinking about genes as causes is counterfactual reasoning, the cornerstone of causal thinking in statistics, medicine, and philosophy. We argue that within-family genetic effects represent the product of a counterfactual comparison in the same way as average treatment effects (ATEs) from randomized controlled trials (RCTs). Both ATEs from RCTs and within-family genetic effects are shallow causes: They operate within intricate causal systems (non-unitary), produce heterogeneous effects across individuals (non-uniform), and are not mechanistically informative (non-explanatory). Despite these limitations, shallow causal knowledge can be used to improve understanding of the etiology of human behavior and to explore sources of heterogeneity and fade-out in treatment effects.

From the 1980s onwards, the Roslin Institute and its predecessor organizations faced budget cuts, organizational upheaval and considerable insecurity. Over the next few decades, it was transformed by the introduction of molecular biology and transgenic research, but remained a hub of animal geneticists conducting research aimed at the livestock-breeding industry. This paper explores how these animal geneticists embraced genomics in response to the many-faceted precarity that the Roslin Institute faced, establishing it as a global centre for pig genomics research through (...) forging and leading the Pig Gene Mapping Project (PiGMaP); developing and hosting resources, such as a database for genetic linkage data; and producing associated statistical and software tools to analyse the data. The Roslin Institute leveraged these resources to play a key role in further international collaborations as a hedge against precarity. This adoption of genomics was strategically useful, as it took advantage of policy shifts at the national and European levels towards funding research with biotechnological potential. As genomics constitutes a set of infrastructures and resources with manifold uses, the development of capabilities in this domain also helped Roslin to diversify as a response to precarity. (shrink)

It is commonly asserted that “death is not a welfare issue” and this has been reflected in welfare legislation and policy in many countries. However, this creates a conflict for many who consider animal welfare to be an appropriate basis for decision-making in animal ethics but also consider that an animal’s death is ethically significant. To reconcile these viewpoints, this paper attempts to formulate an account of death as a welfare issue. Welfare issues are issues that refer to evaluations concerning (...) an animal’s interests. This includes evaluations that refer only to comparisons between the presence and absence of states, including positive states. This means that an animal’s death may be a welfare issue insofar as it leads to the exclusion of relevant positive states. This allows us to deny that death is necessarily not a welfare issue.

SummaryThe Gainj of highland Papua New Guinea do not use contraception but have a total fertility rate of only 4·3 live births per woman, one of the lowest ever recorded in a natural fertility setting. From an analysis of cross-sectional demographic and endocrinological data, the causes of low reproductive output have been identified in women of this population as: late menarche and marriage, a long interval between marriage and first birth, a high probability of widowhood at later reproductive ages, low (...) effective fecundability and prolonged lactational amenorrhoea. These are combined with near-universal marriage, a low prevalence of primary sterility and a pattern of onset of secondary sterility similar to that found in other populations. Of all the factors limiting fertility, by far the most important are those involved in birth spacing, especially lactational amenorrhoea. (shrink)

It is nearly 10 years since Patrick Haggard and colleagues first reported the ‘intentional binding’ effect . The intentional binding effect refers to the subjective compression of the temporal interval between a voluntary action and its external sensory consequence. Since the first report, considerable interest has been generated and a fascinating array of studies has accumulated. Much of the interest in intentional binding comes from the promise to shed light on human agency. In this review we survey studies on intentional (...) binding, focusing, in particular, on the link between intentional binding and the sense of agency . We suggest that, whilst it is yet to be fully explicated, the link between intentional binding and the sense of agency is compelling. We conclude by considering outstanding questions and future directions for research on intentional binding. (shrink)

Linkage arguments, which defend a controversial right by showing that it is indispensable or highly useful to an uncontroversial right, are sometimes used to defend the right to health care. This article evaluates such arguments when used to defend RHC. Three common errors in using linkage arguments are neglecting levels of implementation, expanding the scope of the supported right beyond its uncontroversial domain, and giving too much credit to the supporting right for outcomes in its area. A familiar linkage argument (...) for RHC focuses on its contributions to the right to life. Among the problems with this argument are that it requires a positive conception of the right to life that is not uncontroversial and that it only justifies the subset of RHC that seeks to prevent loss of life. A linkage argument for RHC with better prospects claims that a well-realized right to health care enhances the realization of a number of uncontroversial rights. (shrink)

This is a set of essays and translations that covers comprehensively all of Japanese philosophy.

How reasonable and rational can science be when its practitioners speak of "revolutions" in their thinking and extol certain theories for their "beauty"? James W. McAllister addresses this question with the first systematic study of the aesthetic evaluations that scientists pass on their theories. P. A. M. Dirac explained why he embraced relativity by saying, "It is the essential beauty of the theory which I feel is the real reason for believing in it." Dirac's claim seems to belie rationalist (...) accounts of science. Using this and a wealth of other historical examples, McAllister explains how scientists' aesthetic preferences are influenced by the empirical track record of theories, describes the origin and development of aesthetic styles of theorizing, and reconsiders whether simplicity is an empirical or an aesthetic virtue of theories. McAllister then advances an innovative model of scientific revolutions, in opposition to that of Thomas S. Kuhn. Three detailed studies demonstrate the interconnection of empirical performance, beauty, and revolution. One examines the impact of new construction materials on the history of architecture. Another reexamines the transition from the Ptolemaic system to Kepler's theory in planetary astronomy, and the third documents the rise of relativity and quantum theory in the twentieth century.

SummaryThe effects of infant suckling patterns on the post-partum resumption of ovulation and on birth-spacing are investigated among the Gainj of highland New Guinea. Based on hormonal evidence, the median duration of lactational anovulation is 20·4 months, accounting for about 75% of the median interval between live birth and next successful conception. Throughout lactation, suckling episodes are short and frequent, the interval changing slowly over time, from 24 minutes in newborns to 80 minutes in 3-year olds. Maternal serum prolactin concentrations (...) decline in parallel with the changes in suckling patterns, approaching the level observed in non-nursing women by about 24 months post-partum. A path analysis indicates that the interval between suckling episodes is the principal determinant of maternal prolactin concentration, with time since parturition affecting prolactin secretion only in so far as it affects suckling frequency. The extremely prolonged contraceptive effect of breast-feeding in this population thus appears to be due to a slow decline in suckling frequency with time since parturition and absence of a decline over time in hypothalamic–pituitary responsiveness to the suckling stimulus.

The Farm Animal Welfare Council’s concept of a Good Life gives an idea of an animal’s quality of life that is over and above that of a mere life worth living. The concept needs explanation and clarification, in order to be meaningful, particularly for consumers who purchase farm animal produce. The concept could allow assurance schemes to apply the label to assessments of both the potential of each method of production, conceptualised in ways expected to enhance consumers’ engagement such as (...) ‘naturalness’ and ‘freedom’; and the concept of a life worth living as a safeguard threshold below which no animal’s actual welfare should fall, based on each animal’s overall affective states. This may provide a framework for development of the Good Life concept, within scientific and sociological fields, in order to allow reliable and influential use by assessors, consumers and retailers.

This article analyzes astrobiology as a cosmopolitical project—the ways in which astrobiological “sensemaking” practices do philosophical, political, cultural, ontological, and ethical work as much as they do scientific work. More specifically, this article argues that astrobiology is engaged in the crafting of a new “origin myth” that makes sense of humanity’s place in the universe during our transition from the Holocene to the Anthropocene. In doing so, this article traces the ways in which astrobiology employs scientific methodologies and engages with (...) popular culture in ways that do four kinds of major work commonly found in origin myths: telling the origin story, demarcating the boundaries between self and the other, giving normative guidance, and declaring a shared societal purpose.

Animals are usually considered to lack the status of autonomous agents. Nevertheless, they do appear to make ostensible choices. This article considers whether, and how, I should respect animals' choices. I propose a concept of volitionality which can be respected if, and insofar as, doing so is in the best interests of the animal. Applying that concept, I will argue that an animals' choices be respected when the relevant human decision maker's capacities to decide are potentially challenged or compromised. For (...) example, it will be best to respect the animals' choice when the human decision maker: lacks accurate knowledge of the animal's subjective experiences; does not know what will lead to desirable experiences or allow for the avoidance of undesirable ones; is biased; is less aware of the animal's specific situation; cannot appreciate all elements comprehensively, including considering any value to the animal being allowed to make and implement a choice, such as where a lack of control or liberty would be unpleasant or where an animal would usefully learn from the process of choice-making; and when the animal's choice is achievable. This additionally suggests that we may often beneficially choose to set up situations that empower animals to make better choices. (shrink)

William James and Education is a dynamic collection of original essays spotlighting William James as a role model for bringing philosophy to bear on the persistent issues of life and education. Using James's philosophical ideas, the contributors evade the polarization and superficiality that permeate the debate around such educational issues as standards versus diversity, cultural consensus versus multiculturalism, religion versus science, and individual freedom versus social determinism. The result is a synthetic collection of essays offering original, unique, (...) and useful insights. One of the most influential of American philosophers, William James is relevant today because he provides a way of understanding human behavior that is both rigorous and humane. James shows how we may soften and sometimes harmonize rigid ideological divisions, such as those plaguing contemporary education, with a pragmatic approach to issues of theory and practice. By reconsidering some of the roots of American thought in James's work, this volume points the way to valuing both uniqueness and universality, among other seemingly opposing concerns. The result is a lively weave of historical and contemporary thought, providing philosophical perspectives on the critical issues facing educators today. (shrink)

The experience of causation is a pervasive product of the human mind. Moreover, the experience of causing an event alters subjective time: actions are perceived as temporally shifted towards their effects [Haggard, P., Clark, S., & Kalogeras, J.. Voluntary action and conscious awareness. Nature Neuroscience, 5, 382-385]. This temporal shift depends partly on advance prediction of the effects of action, and partly on inferential "postdictive" explanations of sensory effects of action. We investigated whether a single factor of statistical contingency could (...) explain both these aspects of causal experience. We studied the time at which people perceived a simple manual action to occur, when statistical contingency indicated a causal relation between action and effect, and when no such relation was indicated. Both predictive and inferential "postdictive" shifts in the time of action depended on strong contingency between action and effect. The experience of agency involves a process of causal learning based on statistical contingency. (shrink)

For many years there has been a debate about the role of the parietal lobe in the generation of behavior. Does it generate movement plans (intention) or choose objects in the environment for further processing? To answer this, we focus on the lateral intraparietal area (LIP), an area that has been shown to play independent roles in target selection for saccades and the generation of visual attention. Based on results from a variety of tasks, we propose that LIP acts as (...) a priority map in which objects are represented by activity proportional to their behavioral priority. We present evidence to show that the priority map combines bottom-up inputs like a rapid visual response with an array of top-down signals like a saccade plan. The spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention. (shrink)

I address the question: “What is fixed on the boundary in the action principles of general relativity?” Four forms of the action are considered: the Einstein action, the Hilbert action, the first order action, and what may be called the cosmological action. The relationships and boundary data of these actions are described geometrically. Formal passage to the “Euclidean” forms of these actions is effected in detail.
