The evolutionary origin of human pair-bonds is uncertain. One hypothesis, supported by data from forgers, suggests that pair-bonds function to provision mothers and dependent offspring during lactation. Similarly, public health data from large-scale industrial societies indicate that single mothers tend to wean their children earlier than do women living with a mate. Here we examine relations between pair-bond stability, alloparenting, and cross-cultural trends in breastfeeding using data from 58 “traditional” societies in the Standard Cross-Cultural Sample (SCCS). Analyses show that stable (...) conjugal relationships were associated with significantly later weaning among the societies in the SCCS. The relationship between pair-bond stability and age at weaning was not mediated by women’s ability to provision themselves or women’s kin support. Availability of alloparental care was also inversely related to age at weaning, and the association was not significantly reduced after controlling for frequency of divorce. This study indicates that among a woman’s kin relationships, a pair-bond with a child’s father is especially supportive of breastfeeding. These cross-cultural findings are further evidence that human pair-bonds may have evolved to support lactation. (shrink)

Extrinsic mortality is a key influence on organisms’ life history strategies, especially on age at maturity. This historical longitudinal study of 125 women in rural Domenica examines effects of extrinsic mortality on human age at maturity and pace of reproduction. Extrinsic mortality is indicated by local population infant mortality rates during infancy and at maturity between the years 1925 and 2000. Extrinsic mortality shows effects on age at first birth and pace of reproduction among these women. Parish death records show (...) huge historical variation in age-specific mortality rates. The infant mortality rate (IMR) in the early 1920s was low, increased dramatically beginning in 1929, and reached a maximum in the 1950s, at which point IMR declined steadily to its present low rate. The mortality rate early in life showed a quadratic association with age at first birth. Women who experienced conditions of low IMR early in life reproduced relatively late in life. Those born into moderately high levels of infant mortality tended to reproduce earlier than those born at low levels. At very high infant mortality levels early in life, women went on to delay reproduction until relatively late, possibly as a result of somatic depletion and energetic stress associated with the conditions that lead to high IMR. Population mortality rates at age of maturity also showed a quadratic association with age at first birth. The pace of reproduction, estimated as number of surviving offspring controlled for maternal age, showed a similar quadratic effect. There were complex interactions between population mortality rates in infancy and at maturity. When extrinsic mortality was high during infancy, extrinsic mortality later in life had little effect on timing of first birth. When extrinsic mortality was low to moderate in infancy, extrinsic mortality later in life had significant effects on adult reproduction. I speculate that these effects are mediated through development of personality facets associated with reproduction. (shrink)

Patterns of human kinship commonly involve preferential treatment of relatives based on lineal descent (lineages) rather than degree of genetic relatedness (kindreds), presenting a challenge for inclusive fitness theory. Here, we examine effects of lineage and kindred characteristics on reproductive success (RS) and number of grandchildren for 130 men and 124 women in a horticultural community on Dominica. Kindreds had little effect on fitness independently of lineage characteristics. Fitness increased with the number of lineal relatives residing in the community but (...) decreased beyond an apparently optimal lineage size, suggesting resource enhancement and competition among kin. Female-biased patrilineage sex ratio was positively associated with men’s fitness, while male-biased matrilineage sex ratio was positively associated with women’s fitness. Number of brothers in the community was negatively associated with men’s, but not women’s, fitness. Parents and number of sisters had no effect on either male or female reproduction; however, women with younger sisters had higher RS, suggesting benefits of kin support for childcare. In sum, imposed norms for lineage social organization may enhance lineal ancestors’ inclusive fitness at a cost to individual inclusive fitness. (shrink)

Household structure may have strong effects on reproduction. This study uses household demographic data for 59 women in a Caribbean village to test evolutionary hypotheses concerning variation in reproductive strategies. Father-absence during childhood, current household composition, and household economic status are predicted to influence age at first birth, number of mates, reproductive success, and pair-bond stability. Criterion variables did not associate in a manner indicative of r- and K-strategies. Father-absence in early childhood had little influence on subsequent reproduction. Household wealth (...) and alloparenting were positively associated with age at first birth. Alloparenting was negatively associated with reproductive success. Women in long-term conjugal unions had higher reproductive success than did single women. Number of adult male kin resident in the household was negatively associated with women’s number of mates.

If parenting behavior influences attachment, then parental investment (PI) theory can predict sex differences and distributions of attachment styles across cultures. Trivers-Willard, local resource competition, and local resource enhancement models make distinct predictions for sex-biased parental responsiveness relevant to attachment. Parental investment and attachment probably vary across cultures in relation to for status, wealth, and well-being.

Kinship and reciprocity are two main predictors of altruism. The ultimatum game has been used to study altruism in many small-scale societies. We used the ultimatum game to examine effects of individuals’ family and kin relations on altruistic behavior in a kin-based horticultural community in rural Dominica. Results show sex-specific effects of kin on ultimatum game play. Average coefficient of relatedness to the village was negatively associated with women’s ultimatum game proposals and had little effect on men’s proposals. Number of (...) brothers in the village was positively associated with men’s ultimatum game proposals and negatively associated with women’s proposals. Similarly, presence of father in the village was associated with higher proposals by men and lower proposals by women. We interpret the effect of brothers on men’s proposals as a consequence of local competition among brothers. We speculate that daughter-biased parental care in this community creates a sense of entitlement among women with brothers, which may explain the inverse relation between number of brothers and women’s ultimatum game proposals. The pattern of results may be consistent with how matrifocality affects cultural models of fairness differently along gender and family lines. (shrink)

This study examines the family environments and hormone profiles of 316 individuals aged 2 months-58 years residing in a rural village on the east coast of Dominica, a former British colony in the West Indies. Fieldwork was conducted over an eight-year period (1988–1995). Research methods and techniques include radioimmunoassay of cortisol and testosterone from saliva samples (N=22,340), residence histories, behavioral observations of family interactions, extensive ethnographic interview and participant observation, psychological questionnaires, and medical examinations.Analyses of data indicate complex, sex-specific effects (...) of family environment on endocrine function. Male endocrine profiles exhibit greater sensitivity to presence of father than do female endocrine profiles. Father-absent males tend to have (a) low cortisol levels during infancy, (b) high or abnormal cortisol profiles during childhood and adolescence, and (c) high cortisol and low testosterone levels during adulthood compared with those of males raised with a resident father. These results indicate that early family environment has significant effects on endocrine response throughout male life histories. (shrink)

Extensive research has demonstrated that rs1360780, a common single nucleotide polymorphism within the FKBP5 gene, interacts with early-life stress in predicting psychopathology. Previous results suggest that carriers of the TT genotype of rs1360780 who were exposed to child abuse show differences in structure and functional activation of emotion-processing brain areas belonging to the salience network. Extending these findings on intermediate phenotypes of psychopathology, we examined if the interaction between rs1360780 and child abuse predicts resting-state functional connectivity (rsFC) between the amygdala (...) and other areas of the salience network. We analyzed data of young European adults from the general population (N = 774; mean age = 18.76 years) who took part in the IMAGEN study. In the absence of main effects of genotype and abuse, a significant interaction effect was observed for rsFC between the right centromedial amygdala and right posterior insula (p <.025, FWE-corrected), which was driven by stronger rsFC in TT allele carriers with a history of abuse. Our results suggest that the TT genotype of rs1360780 may render individuals with a history of abuse more vulnerable to functional changes in communication between brain areas processing emotions and bodily sensations, which could underlie or increase the risk for psychopathology.

This work, first published in 1985, offers a general interpretation of Hume's Treatise of Human Nature. Most Hume scholarship has either neglected or downplayed an important aspect of Hume's position - his scepticism. This book puts that right, examining in close detail the sceptical arguments in Hume's philosophy.

This collection of 21 essays explores the creative interaction among the cognitive neurosciences, philosophy, and theology. It is the result of an international research conference co-sponsored by the Vatican Observatory, Rome, and the Center for Theology and the Natural Sciences, Berkeley.

This article introduces three arguments that share a single conclusion: that a comprehensive science of language cannot describe relations of semantic reference, i.e. word–world relations. Spelling this out, if there is to be a genuine science of linguistic meaning, then a theory of meaning cannot involve assigning external, real-world, objects to names, nor sets of external objects to predicates, nor truth values to sentences. Most of the article tries to explain and defend this broad conclusion. The article also presents, in (...) a very limited way, a positive alternative to external-referent semantics for expressions. This alternative has two parts: first, that the meanings of words and sentences are mental instructions, not external things; second, that it is people who refer by using words and sentences, and word/sentence meanings play but a partial role in allowing speakers to talk about the world.

In what follows, I introduce a pragmatics-oriented approach to non-sentential speech, and defend it against two recent attacks. Among other things, I will rehearse and elaborate a defense against the idea that much, or even all, of such speech is actually syntactically elliptical—and hence should be treated semantically, rather than pragmatically. The chapter is structured as follows. In Section 1 I introduce the phenomenon, contrast semantic versus pragmatic approaches to it, and explain some of what hinges on which approach is (...) taken. In Section 2 I present Jason Stanley’s objections to the pragmatics-oriented approach, and his counterproposal that all truth-conditional effects of context on what is asserted can be traced to elements of underlying structure. In Section 3 I canvass numerous varieties of ellipsis. The focus in Section 3 will be on what kind of “ellipsis” is required if the pragmatics-oriented approach is actually to be rejected rather than being recast in other terms. In Section 4 I respond to.. (shrink)

The traditional problem of evil is set forth, by no means for the first time, in Part X of Hume's Dialogues Concerning Natural Religion in these familiar words: ‘Is [God] willing to prevent evil, but not able? then he is impotent. Is he able, but not willing? then he is malevolent. Is he both able and willing? whence then is evil?’ This formulation of the problem of evil obviously suggests an argument to the effect that the existence of evil in (...) the world demonstrates that God does not exist. The purpose of this paper is to examine this argument, with a view to showing that while it is not a conclusive argument, it is much stronger than some apologists for traditional theism allow.

Chapter III contains several puzzles and unexpected features. The first puzzle regards the chapter’s relationship to Chapter IV: Natural Selection. Both chapters treat of natural selection, so what distinguishes them? Is it that Chapter IV indicates the intelligence behind nature’s selections and Chapter III introduces the analog of intelligence? And is it that Chapter III suggests that natural selection performs an eliminative function, while Chapter IV shows the positive impact of selection? In Chapter IV, and in many subsequent chapters, natural (...) selection, Darwin says, operates only for the good of each individual creature, though Chapter III suggests it destroys most individuals. Darwin asserts that he uses the term “struggle” metaphorically, which raises the question of the explanatory weight his metaphors carry, such metaphors as "the face of nature.” There are a number of unexpected features of Darwin’s analysis displayed in the chapter: for example, his introduction of a new concept of the selective environment and the several experiments he performs to establish his theory, e.g., from mathematical and thought experiments to controlled empirical experiments. Chapter III is a rich though puzzling chapter. (shrink)

This is a much-needed development from the first edition that provides an update on the theory and research on love by world-renowned scientific experts. It explores love from a diverse range of standpoints: social-psychological, evolutionary, neuropsychological, clinical, cultural, and even political. It considers questions such as: how men and women differ in their love, what makes us susceptible to jealousy and envy in relationships, how love differs across various cultures? As the neuropsychological basis of love is examined, this study showcases (...) what attracts people to one another, why love has developed the way it has over time, and what evolutionary purpose it serves. It also analyses why and when love relationships both succeed and fail, which means readers will be rewarded with a better understanding of their own relationships and those of others, as well as what can be done to build a lasting, loving relationship.

The principle of the child's right to an open future was first proposed by the legal philosopher Joel Feinberg and developed further by bioethicist Dena Davis. The principle holds that children possess a unique class of rights called rights in trust—rights that they cannot yet exercise, but which they will be able to exercise when they reach maturity. Parents should not, therefore, take actions that permanently foreclose on or pre-empt the future options of their children, but leave them the greatest (...) possible scope for exercising personal life choices in adulthood. Davis particularly applies the principle to genetic counselling, arguing that parents should not take deliberate steps to create physically abnormal children, and to religion, arguing that while parents are entitled to bring their children up in accordance with their own values, they are not entitled to inflict physical or mental harm, neither by omission nor commission. In this paper, I aim to elucidate the open future principle, and consider whether it is applicable to non-therapeutic circumcision of boys, whether performed for cultural/religious or for prophylactic/health reasons. I argue that the principle is highly applicable to non-therapeutic circumcision, and conclude that non-therapeutic circumcision would be a violation of the child's right to an open future, and thus objectionable from both an ethical and a human rights perspective.

This book is a small handbook designed to give Institutional Review Board (IRB) members the information they need to protect the rights and welfare of research subjects in a way that is both effective and efficient. The chapters of this book are short and to the point. Topic-specific chapters list the criteria IRB members should use to determine how to vote on specific kinds of studies and offer practical advice on what IRB members should do before and during full-committee meetings.

Robert Roth, among the first few Catholics to write favorably, even if critically, about American pragmatism, presents here a creative piece of comparative philosophy in which he achieves a long-term goal of attempting a reconciliation between pragmatism and a classical spiritual and religious perspective.

James had argues that the classical empiricists, Locke and Hume, did not go far enough in their account of experience. They missed some of (...) its most important aspects, namely connections and relations, and as a result they were left with discrete sense data and sense objects. (shrink)

In this book, Dr. Robert J. Levine reviews federal regulations, ethical analysis, and case studies in an attempt to answer these questions.

"All art should become science and all science art; poetry and philosophy should be made one." Friedrich Schlegel's words perfectly capture the project of the German Romantics, who believed that the aesthetic approaches of art and literature could reveal patterns and meaning in nature that couldn't be uncovered through rationalistic philosophy and science alone. In this wide-ranging work, Robert J. Richards shows how the Romantic conception of the world influenced (and was influenced by) both the lives of the people (...) who held it and the development of nineteenth-century science. Integrating Romantic literature, science, and philosophy with an intimate knowledge of the individuals involved—from Goethe and the brothers Schlegel to Humboldt and Friedrich and Caroline Schelling—Richards demonstrates how their tempestuous lives shaped their ideas as profoundly as their intellectual and cultural heritage. He focuses especially on how Romantic concepts of the self, as well as aesthetic and moral considerations—all tempered by personal relationships—altered scientific representations of nature. Although historians have long considered Romanticism at best a minor tributary to scientific thought, Richards moves it to the center of the main currents of nineteenth-century biology, culminating in the conception of nature that underlies Darwin's evolutionary theory. Uniting the personal and poetic aspects of philosophy and science in a way that the German Romantics themselves would have honored, The Romantic Conception of Life alters how we look at Romanticism and nineteenth-century biology.

Martin Luther affirms his theological position by saying “Here I stand. I can do no other.” Supposing that Luther’s claim is true, he lacks alternative possibilities at the moment of choice. Even so, many libertarians have the intuition that he is morally responsible for his action. One way to make sense of this intuition is to assert that Luther’s action is indirectly free, because his action inherits its freedom and moral responsibility from earlier actions when he had alternative possibilities and (...) those earlier directly free actions formed him into the kind of person who must refrain from recanting. Surprisingly, libertarians have not developed a full account of indirectly free actions. I provide a more developed account. First, I explain the metaphysical nature of indirectly free actions such as Luther’s. Second, I examine the kind of metaphysical and epistemic connections that must occur between past directly free actions and the indirectly free action. Third, I argue that an attractive way to understand the kind of derivative moral responsibility at issue involves affirming the existence of resultant moral luck. (shrink)

The risk of stroke for a child with SCD is many times greater than that of a healthy child without SCD or heart disease. There is a technique that allows the identification of the children with SCD who have high risk even within this relatively high-risk group. And there is a highly effective preventive treatment. While this would on the surface appear to be a straightforward medical decision, it is not. One must weigh the benefits of preventing permanent brain damage (...) against the risks of infection from transfused blood, iron overload, which is the result of the frequent transfusions, and rare transfusion reactions.

Sickle cell anemia is a disease characterized by abnormal hemoglobin structure. There is a mutation in the beta-globin gene that changes the sixth amino acid from glutamic acid to valine causing the mutated hemoglobin to polymerize reversibly when deoxygenated to form a gelatinous network of fibrous polymers that stiffen and distort the red blood cell membrane. This leads to episodes of microvascular vasoocclusion and premature RBC destruction leading to hemolytic anemia. For reasons that are unclear, some children develop a large (...) artery vasculopathy involving the intracranial arteries supplying the brain.The risk of stroke for a child with SCD is many times greater than that of a healthy child without SCD or heart disease.
