Previous research indicates that birth order is a strong predictor of familial sentiments, with middleborns less family-oriented than first- or last-borns. In this research, effects of sex and birth order on the actual frequency of contact with maternal and paternal kin were examined in two studies. In Study 1, one hundred and forty undergraduates completed a questionnaire relating to the amount of time they spent in contact with specific relatives, while in Study 2, one hundred and twelve undergraduates completed the (...) same questionnaire with the addition of two questions relating to the subjects’ parents’ birth orders. Subjects were more likely to have frequent contact with maternal, as opposed to paternal, kin and women experienced more frequent contact than men with relatives in general. The birth order of subjects did not appear to have a significant influence on contact but the birth order of the subjects’ parents did, with the offspring of middleborn mothers having relatively little contact with maternal grandparents and the offspring of middleborn fathers having relatively little contact with paternal grandparents. These sex and birth order differences are discussed in relation to possible differences in how women and men use kinship ties and in terms of how birth order may influence parental solicitude.

Previous studies (Salmon 1999; Salmon and Daly 1998) have found that sex and birth order are strong predictors of familial sentiments. Middleborns tend to be less family-oriented than firstborns or lastborns, while sex differences seem to focus on the utility of kin in certain domains. If this is a reflection of middleborns receiving a lesser degree of support from kin (particularly in terms of parental investment), are middleborns turning to reciprocal alliances outside the family, becoming friendship specialists? Are (...) there comparable birth order differences with respect to mating strategies? In this study, the impact of birth order on attitudes toward family, friends, and mating were examined. Two hundred and forty-five undergraduates completed a questionnaire relating to their attitudes toward friends and family as well as some aspects of mating behavior. Birth order did have a significant impact in several areas. Middleborns expressed more positive views toward friends and less positive opinions of family in general. They were less inclined to help family in need than firstborns or lastborns. Mating strategies also appeared to be influenced by birth order, most notably in the area of infidelity, with middleborns being the least likely birth order to cheat on a sexual partner. (shrink)

The target article is focused on locating the popularity of imaginary worlds in our adaptations for exploration. This commentary touches on developmental influences, vicarious enjoyment, the challenging of societal mores, plot, and whether men and women are drawn to the same features in the same ways.

The target article raises important questions about the applicability of experimental social psychology research on topics with policy implications. This commentary focuses on the importance of attending to a variety of factors to improve ecological validity as well as considering the ultimate factors shaping behavior and the role of natural categories in the stability of stereotypes and their influence.

It is commonly assumed that the desire for a thin female physique and its pathological expression in eating disorders result from a social pressure for thinness. However, such widespread behavior may be better understood not merely as the result of arbitrary social pressure, but as an exaggerated expression of behavior that may have once been adaptive. The reproductive suppression hypothesis suggests that natural selection shaped a mechanism for adjusting female reproduction to socioecological conditions by altering the amount of body fat. (...) In modern Western culture, social and ecological cues, which would have signaled the need for temporary postponement of reproduction in ancestral environments, may now be experienced to an unprecedented intensity and duration.

Utilizing an evolutionary perspective has proven fruitful in a number of areas of interest outside of the standard psychological or anthropological topics. This includes a wide range of fields from applied disciplines such as law, criminology, medicine, and marketing, to the study of the imagined worlds found in art and literature, the domains of the humanities. A number of excellent books, as well as numerous articles, detail the impressive work done in applying evolutionary insights to the study of art and (...) literature. This article focuses on evolutionarily informed explorations of popular culture, an area that, only relatively recently, has benefited from research taking this approach. The existing scholarship in this area will be reviewed, and future directions and challenges highlighted. (shrink)

How far has the Darwinian revolution come? To what extent have evolutionary ideas penetrated into the social sciences and humanities? Are the “science wars” over? Or do whole blocs of disciplines face off over an unbridgeable epistemic gap? To answer questions like these, contributors to top journals in 22 disciplines were surveyed on their beliefs about human nature, culture, and science. More than 600 respondents completed the survey. Scoring patterns divided into two main sets of disciplines. Genetic influences were emphasized (...) in the evolutionary social sciences, evolutionary humanities, psychology, empirical study of the arts, philosophy, economics, and political science. Environmental influences were emphasized in most of the humanities disciplines and in anthropology, sociology, education, and women's or gender studies. Confidence in scientific explanation correlated positively with emphasizing genetic influences on behavior, and negatively with emphasizing environmental influences. Knowing the current actual landscape of belief should help scholars avoid sterile debates and ease the way toward fruitful collaborations with neighboring disciplines. (shrink)

Using data collected from people with at least one brother and one sister, and consistent with an evolutionary perspective, we find that older men and women (a) are more upset by a brother’s partner’s sexual infidelity than by her emotional infidelity and (b) are more upset by a sister’s partner’s emotional infidelity than by his sexual infidelity. There were no effects of participant sex or sex of in-law on upset over a sibling’s partner’s infidelities, but there was an effect of (...) participant sex on reports of upset over one’s own partner’s infidelities. The results suggest that the key variable among older participants is the sex of the sibling or, correspondingly, the sex of the sibling’s partner, as predicted from an evolutionary analysis of reproductive costs, and not the sex of the participant, as predicted from a socialization perspective. Discussion offers directions for future work on jealousy. (shrink)

Wesley Salmon is renowned for his seminal contributions to the philosophy of science. He has powerfully and permanently shaped discussion of such issues as lawlike and probabilistic explanation and the interrelation of explanatory notions to causal notions. This unique volume brings together twenty-six of his essays on subjects related to causality and explanation, written over the period 1971-1995. Six of the essays have never been published before and many others have only appeared in obscure venues. The volume includes a (...) section of accessible introductory pieces, as well as more advanced and technical pieces, and will make essential work in the philosophy of science readily available to both scholars and students.

The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined even if it is not sufficiently formal and precise to belong to mathematics proper (in a narrow sense)—and even if (as many have asserted) for that reason the Church–Turing thesis is unprovable. It is proved logically that the class of effective procedures is not decidable, i.e., that no effective procedure is possible for ascertaining whether a given procedure is effective. This (...) undecidability result is proved directly from the notion itself of an effective procedure, without reliance on any (partly) mathematical lemma, conjecture, or thesis invoking recursiveness or Turing-computability. In fact, there is no reliance on anything very mathematical. The proof does not even appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of an effective procedure. Though the result that effectiveness is undecidable is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure invariably terminates with the correct verdict.

Designed for students with no prior training in logic, INTRODUCTION TO LOGIC AND CRITICAL THINKING offers an accessible treatment of logic that enhances understanding of reasoning in everyday life. The text begins with an introduction to arguments. After some linguistic preliminaries, the text presents a detailed analysis of inductive reasoning and associated fallacies. This order of presentation helps to motivate the use of formal methods in the subsequent sections on deductive logic and fallacies. Lively and straightforward prose assists students in (...) gaining facility with the sometimes challenging concepts of logic. By combining a sensitive treatment of ordinary language arguments with a simple but rigorous exposition of basic principles of logic, the text develops students' understanding of the relationships between logic and language, and strengthens their skills in critical thinking.

Alonzo Church famously provided three principal competing criteria for “strict synonymy,” i.e., sameness of semantic content. These are his Alternatives (0), (1), and (2)—numbered in order of increasing course-grainedness of content. On Alternative (2), expressions are deemed strictly synonymous iff they are logically equivalent. This criterion seems hopeless as an account of the objects of propositional attitude. On Alternative (1), expressions are deemed synonymous iff they are λ-convertible. Alternative (1) also evidently conflicts with discourse about the attitudes. On Alternative (0), (...) expressions are deemed strictly synonymous iff they are “synonymously isomorphic” in Church’s sense. On Alternative (0), semantic content is so fine-grained that not even “Romeo loves Juliet” and “Juliet is loved by Romeo” qualify as strictly synonymous. A fourth alternative, here called “Alternative (3),” deems expressions strictly synonymous iff they are co-intensional, i.e., they have the same semantic extension with respect to the same possible worlds. This criterion’s notion of content is even more course grained than that of Alternative (2). Several objections to Alternative (3) are considered.

The concept of a proposition is important in several areas of philosophy and central to the philosophy of language. This collection of readings investigates many different philosophical issues concerning the nature of propositions and the ways they have been regarded through the years.

Soames, and Nathan Salmon. (shrink)

A new philosophical analysis is provided of the notorious Sleeping Beauty Problem. It is argued that the correct solution is one-third, but not in the way previous philosophers have typically meant this. A modified version of the Problem demonstrates that neither self-locating information nor amnesia is relevant to the core Problem, which is simply to evaluate the conditional chance of heads given an undated Monday-or-Tuesday awakening. Previous commentators have failed to appreciate the significance of the information that Beauty gains upon (...) waking, and which is relevant to the conditional chance of heads: de re acquaintance with the awakening itself and the non-locating knowledge that it is an experimental awakening. David Lewis and company are committed to several unjustifiable and unacceptable probability assessments. Previous commentators have in effect confused the information that Beauty undergoes this particular experimental awakening for the information that she undergoes some experimental awakening or other. Lewis in particular thereby illegitimately tips the scales both in favor of heads and in favor of Monday. The Sleeping Beauty Problem is equivalent to a ball-in-urn word problem in elementary probability theory. (shrink)

Truth is standardly considered a requirement on epistemic acceptability. But science and philosophy deploy models, idealizations and thought experiments that prescind from truth to achieve other cognitive ends. I argue that such felicitous falsehoods function as cognitively useful fictions. They are cognitively useful because they exemplify and afford epistemic access to features they share with the relevant facts. They are falsehoods in that they diverge from the facts. Nonetheless, they are true enough to serve their epistemic purposes. Theories that contain (...) them have testable consequences, hence are factually defeasible. (shrink)

Toward a theory of n-tuples of individuals and concepts as surrogates for Russellian singular propositions and singular concepts. Alonzo Church proposed a powerful and elegant theory of sequences of functions and their arguments as singular-concept surrogates. Church’s account accords with his Alternative (0), the strictest of his three competing criteria for strict synonymy. The currently popular objection to strict criteria like (0) on the basis of the Russell-Myhill paradox is here rebutted. As Church recognized, Russell-Myhill is not a problem specifically (...) for Alternative (0). Rather it is a disproof of unrestricted concept comprehension. Unrestricted comprehension is also inconsistent with facts about sets of properties. It is demonstrated furthermore that the principal rival conception of propositions--propositions conceived as classes of possible worlds--is subject to a fatal philosophical collapse: It follows on that conception, given that each of us is fallible, that everyone believes everything. Although it is far superior to its principal rival conception, Church’s proposed theory is vulnerable under (0) to a version of Russell’s notorious Gray’s /Elegy/ objection. Some amendments to Church’s proposal are proffered that address Russell’s objection, including an amendment first proposed in the present author’s /Frege’s Puzzle/ (1986). Church’s response (personal correspondence) is considered. (shrink)

This is a non-technical version of "The Decision Problem for Effective Procedures." The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined, even if it does not have a purely mathematical definition—and even if (as many have asserted) for that reason, the Church–Turing thesis (that the effectively calculable functions on natural numbers are exactly the general recursive functions), cannot be proved. However, it is logically provable from the notion of an (...) effective procedure--without reliance on any (partially) mathematical thesis or conjecture concerning effective procedures, such as the Church–Turing thesis--that the class of effective procedures is undecidable, i.e., that no effective procedure is possible for ascertaining whether a given procedure is effective. The proof does not appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of such a procedure. Though this undecidability result itself is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure is, in fact, a decision procedure, i.e., effective—for example, that it invariably terminates with the correct verdict.

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)

Psychologists and philosophers have argued that the capacity for perseverance or “grit” depends both on willpower and on a kind of epistemic resilience. But can a form of hopefulness in one’s future success also constitute a source of grit? I argue that substantial practical hopefulness, as a hope to bring about a desired outcome through exercises of one’s agency, can serve as a distinctive ground for the capacity for perseverance. Gritty agents’ “practical hope” centrally involves an attention-fuelled, risk-inclined weighting of (...) two competing concerns over action: when facing the decision of whether to persevere, hopeful gritty agents prioritize the aim of choosing a course of action which might go very well over that of choosing a course of action which is very likely to go fairly well. By relying on the notion of a “risk-inclined attentional pattern” as a dimension of gritty agents’ practical hope, we can explain that form of hope’s contribution to their motivation and practical rationality, especially on a risk-weighted expected utility framework. The upshot is a more pluralistic view of the sources of grit. (shrink)

In November 1996, Catherine Clément and Julia Kristeva began a correspondence exploring the subject of the sacred. In this collection of those letters Catherine Clément approaches the topic from an anthropologist's point of view while Julia Kristeva responds from a psychoanalytic perspective. Their correspondence leads them to a controversial and fundamental question: is there anything sacred that can at the same time be considered strictly feminine? The two voices of the book work in tandem, fleshing out ideas and (...) blending together into a melody of experience. The result is a dialogue that delves into the mysteries of belief -- the relationship between faith and sexuality, the body and the senses -- which, Clément and Kristeva argue, women feel with special intensity. Although their discourse is not necessarily about theology, the authors consider the role of women and femininity in the religions of the world, from Christianity and Judaism to Confucianism and African animism. They are the first to admit that what they have undertaken is "as impossible to accomplish as it is fascinating." Nevertheless, their wide-ranging and exhilarating dialogue succeeds in raising questions that are perhaps more important to ask than to answer. (shrink)

Is it possible to apply a theoretical approach to ethics? The French philosopher Catherine Chalier addresses this question with an unusual combination of traditional ethics and continental philosophy. In a powerful argument for the necessity of moral reflection, Chalier counters the notion that morality can be derived from theoretical knowledge. Chalier analyzes the positions of two great moral philosophers, Kant and Levinas. While both are critical of an ethics founded on knowledge, their criticisms spring from distinctly different points of (...) view. Chalier reexamines their conclusions, pitting Levinas against (and with) Kant, to interrogate the very foundations of moral philosophy and moral imperatives. She provides a clear, systematic comparison of their positions on essential ideas such as free will, happiness, freedom, and evil. Although based on a close and elegant presentation of Kant and Levinas, Chalier's book serves as a context for the development of the author's own reflections on the question "What am I supposed to do?" and its continued importance for contemporary philosophy.

I defend the thesis that friendship can constitutively require epistemic irrationality against a recent, forceful challenge, raised by proponents of moral and pragmatic encroachment. Defenders of the “encroachment strategy” argue that exemplary friends who are especially slow to believe that their friends have acted wrongly are simply sensitive to the high prudential or moral costs of falsely believing in their friends’ guilt. Drawing on psychological work on epistemic motivation (and in particular on the notion of “need for closure”), I propose (...) a different picture of what friendship requires in the doxastic realm. I argue that contrary to what the encroachment strategy suggests, exemplary friends’ belief formation ought not be guided by a concern with accuracy or error avoidance, but instead by a need to avoid a “specific closure” – namely, a need to avoid concluding in their friends’ guilt. I propose that exemplary friendship often generates a defeasible, doxastic obligation to exemplify such a need, despite its inherent corrupting effects on exemplary friends’ epistemic faculties.

Hope is often seen as at once valuable and dangerous: it can fuel our motivation in the face of challenges, but can also distract us from reality and lead us to irrationality. How can we learn to “hope well,” and what does “hoping well” involve? Contemporary philosophers disagree on such normative questions about hope and also on how to define hope as a mental state. This article explores recent philosophical debates surrounding the concept of hope and the norms governing hope. (...) It also underlies hope's significance for the philosophy of emotion and the ethics of interpersonal relations. (shrink)

Counterpath is a collaborative work by Catherine Malabou and Jacques Derrida that answers to the gamble inherent in the idea of “travelling with” the philosopher of deconstruction. Malabou's readerly text of quotations and commentary demonstrates how Derrida's work, while appearing to be anything but a travelogue, is nevertheless replete with references to geographical and topographical locations, and functions as a kind of counter-Odyssey through meaning, theorizing, and thematizing notions of arrival, drifting, derivation, and catastrophe. In fact, by going straight (...) to the heart of the Derridean idea of “spacing,” she finally makes it seem as though Derrida has never written about anything but travel. Malabou's text is punctuated by a series of postcards received by Derrida from destinations such as Istanbul and Porto, Laguna Beach and Athens, which are inspired by his reading of her evolving discussion. Writing in a familiar and unguarded manner, as if he were “on vacation” from his own writing, Derrida still remains totally faithful to that work and invites the reader to reflect on much of what haunts his texts as well as his daily life, questions of distance and death, the relation to the other, and exile.

Pursuing difficult long-term goals typically involves encountering substantial evidence of possible future failure. If decisions to pursue such goals are serious only if one believes that one will act as one has decided, then some of our lives’ most important decisions seem to require belief against the evidence. This is the puzzle of difficult action, to which I offer a solution. I argue that serious decisions to φ do not have to give rise to a belief that one will φ, (...) but can instead be accompanied by a hope to φ. Hope can motivate and rationalize the various actions that we associate with serious commitment. It can also account for the existence of special pressures to adopt an agential stance toward one’s future. Because hope can be cognitively rational when belief is not, there is no problematic tension between the ideal of epistemic rationality and the phenomenon of difficult action. (shrink)
