The “reproductive suppression hypothesis” states that the strong desire of adolescent girls in our culture to control their weight may reflect the operation of an adaptive mechanism by which ancestral women controlled the timing of their sexual maturation and hence first reproduction, in response to cues about the probable success of reproduction in the current situation. We develop a model based on this hypothesis and explore its behavior and evolutionary and psychological implications across a range of parameter values. We use (...) the process of model development to identify assumptions implicit in the reproductive suppression hypothesis and variables that need to be measured in order to investigate it more fully. In addition, because costs were probably associated with weight control, an important part of this analysis is the specification of situations in which the benefits of adaptive adjustment of the maturation schedule could have outweighed the costs of achieving that adjustment by slowing adolescent weight gain.

We present a quantitative model of sex allocation to investigate whether the simple “rules of thumb” suggested by Trivers and Willard (1973) would really maximize numbers of grandchildren in human populations. Using demographic data from the !Kung of southern Africa and the basic assumptions of the Trivers-Willard hypothesis, we calculate expected numbers of grandchildren based on age- and sex-specific reproductive value. Patterns of parental investment that would maximize numbers of expected grandchildren often differ from the Trivers-Willard rules. In particular, the (...) optimum parental behavior is sensitive to population dynamics, type of parental investment, and, most important, relative ages of sons and daughters. It is doubtful whether a parent blindly following the simple Trivers-Willard rules would maximize numbers of expected grandchildren, on average. In addition, we show that sex-specific infanticide will almost never achieve the goal of maximizing expected numbers of grandchildren. (shrink)

I claim that our desire to be special motivates us to suppose that if we were not God created, we must be self-created. I also claim that Stephen J Gould's claims about punctuated equilibrium, the absence of directional selection, and exaptations, when taken together, lead to kind of secular creationism. I introduce the notion of “adaptive effects” and argue that a focus on the actual physiological and psychological mechanisms that produce adaptations provides a way out of the exaptation dilemma.

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.

Why is female violence a taboo? We suggest that both men and women actively contribute to the creation of this stigma. Men may benefit because nonaggressive women may make better mothers and be more faithful and fertile. Females may benefit by downplaying their aggressive nature because they will be perceived as more valuable mates and because they will be more accepted within female social groups.

Supporting Hamilton’s inclusive fitness theory, archival analyses of inheritance patterns in wills have revealed that people invest more of their estates in kin of closer genetic relatedness. Recent classroom experiments have shown that this genetic relatedness effect is stronger for relatives of direct lineage (children, grandchildren) than for relatives of collateral lineage (siblings, nieces, nephews). In the present research, multilevel modeling of more than 1,000 British Columbian wills revealed a positive effect of genetic relatedness on proportions of estates allocated to (...) relatives. This effect was qualified by an interaction with lineage, such that it was stronger for direct than for collateral relatives. Exploratory analyses of the moderating role of benefactors’ sex and estate values showed the genetic relatedness effect was stronger among female and wealthier benefactors. The importance of these moderators to understanding kin investment in modern humans is discussed. (shrink)

This seminal work by political philosopher C.B. Macpherson was first published by the Clarendon Press in 1962, and remains of key importance to the study of liberal-democratic theory half-a-century later. In it, Macpherson argues that the chief difficulty of the notion of individualism that underpins classical liberalism lies in what he calls its "possessive quality" - "its conception of the individual as essentially the proprietor of his own person or capacities, owing nothing to society for them." Under such a conception, (...) the essence of humanity becomes freedom from dependence on the wills of others; society is little more than a system of economic relations; and political society becomes a means of safeguarding private property and the system of economic relations rooted in property. As the New Statesman declared: "It is rare for a book to change the intellectual landscape. It is even more unusual for this to happen when the subject is one that has been thoroughly investigated by generations of historians.... Until the appearance of Professor Macpherson's book, it seemed unlikely that anything radically new could be said about so well-worn a topic. The unexpected has happened, and the shock waves are still being absorbed." A new introduction by Frank Cunningham puts the work in a twenty-first-century context. (shrink)

In _Real Natures and Familiar Objects_ Crawford Elder defends, with qualifications, the ontology of common sense. He argues that we exist -- that no gloss is necessary for the statement "human beings exist" to show that it is true of the world as it really is -- and that we are surrounded by many of the medium-sized objects in which common sense believes. He argues further that these familiar medium-sized objects not only exist, but have essential properties, which we (...) are often able to determine by observation. The starting point of his argument is that ontology should operate under empirical load -- that is, it should give special weight to the objects and properties that we treat as real in our best predictions and explanations of what happens in the world. Elder calls this presumption "mildly controversial" because it entails that arguments are needed for certain widely assumed positions such as "mereological universalism". Elder begins by defending realism about essentialness. He then defends this view of familiar objects against causal exclusion arguments and worries about vagueness. Finally, he argues that many of the objects in which common sense believes really exist, including artifacts and biological devices shaped by natural selection, and that we too exist, as products of natural selection.

In The Origin of Species (1859) Darwin challenged many of the most deeply-held beliefs of the Western world. Arguing for a material, not divine, origin of species, he showed that new species are achieved by "natural selection." The Origin communicates the enthusiasm of original thinking in an open, descriptive style, and Darwin's emphasis on the value of diversity speaks more strongly now than ever. As well as a stimulating introduction and detailed notes, this edition offers a register of the many (...) writers referred to by Darwin in the text. (shrink)

Explores contemporary controversies in bioethics from a Hindu perspective. S. Cromwell Crawford breaks new ground in this provocative study of Hindu bioethics in a Western setting. He provides a new moral and philosophical perspective on fascinating and controversial bioethical issues that are routinely in the news: cloning, genetic engineering, the human genome project, reproductive technologies, the end of life, and many more. This Hindu perspective is particularly noteworthy because of India's own indigenous medical system, which is stronger than ever (...) and drawing continued interest from the West. The Hindu bioethics presented in this book are philosophically pluralistic and ethically contextual, giving them that conceptual flexibility which is often missing in Western religions, but which is demanded by the twenty-first century's complex moral problems. Comprehensive in scope and passionate in nature, Crawford's study is an important resource for analyses of practical ethics, bioethics, and health care. (shrink)

Abstract According to Russellianism, the content of a Russellian thought, in which a person ascribes a monadic property to an object, can be represented as an ordered couple of the object and the property. A consequence of this is that it is not possible for a person to believe that a is F and not to believe b is F, when a=b. Many critics of Russellianism suppose that this is possible and thus that Russellianism is false. Several arguments for this (...) claim are criticized and it is argued that Russellians need not appeal to representational notions in order to defeat them. Contrary to popular opinion, the prospects for a pure Russellianism, a Russellianism without representations, are in fact very good. (shrink)

Should engineering ethics be taught? Despite the obvious truism that we all want our students to be moral engineers who practice virtuous professional behavior, I argue, in this article that the question itself obscures several ambiguities that prompt preliminary resolution. Upon clarification of these ambiguities, and an attempt to delineate key issues that make the question a philosophically interesting one, I conclude that engineering ethics not only should not, but cannot, be taught if we understand “teaching engineering ethics” to mean (...) training engineers to be moral individuals (as some advocates seem to have proposed). However, I also conclude that there is a justification to teaching engineering ethics, insofar as we are able to clearly identify the most desirable and efficacious pedagogical approach to the subject area, which I propose to be a case study-based format that utilizes the principle of human cognitive pattern recognition.

The essays collected in this volume all explore the problem of the relation between moral philosophy and modernity. Charles Larmore addresses this problem by attempting to define the way distinctive forms of modern experience should orientate our moral thinking. Charles Larmore wonders whether the dominant forms of modern philosophy have not become blind to important dimensions of the moral life. The book argues against recent attempts to return to the virtue-centered perspective of ancient Greek ethics. As well as (...) exploring the differences between ancient and modern ethics, the author examines such topics as the roles of reason and history in our moral understanding, the inadequacy of philsophical naturalism, and the foundations of modern liberalism. There are also extended discussions of a number of leading contemporary philosophers: Rawls, Habermas, Williams and Rorty. (shrink)

This book proposes a new paradigm for the interpretation of Plato's early and middle dialogues. Rejecting the usual assumption of a distinct 'Socratic' period in the development of Plato's thought, this view regards the earlier works as deliberate preparation for the exposition of Plato's mature philosophy. Differences between the dialogues do not represent different stages in Plato's own thinking but rather different aspects and moments in the presentation of a new and unfamiliar view of reality. Once the fictional character of (...) the Socratic genre is recognised, there is no reason to regard Plato's early dialogues as representing the philosophy of the historical Socrates. The result is a unified interpretation of all of the dialogues down to the Republic and the Phaedrus. (shrink)

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that (...) avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. (shrink)

This paper explores corporate charitable giving disclosures in order to question the extent to which corporations can claim that their philanthropy activities are charitable at all. Exploration of these issues is carried out by means of a tropological analysis that focuses on the different linguistic tropes within the philanthropy disclosures of 52 companies, namely metaphor and synecdoche. The results reveal a number of complex and contradictory things. Primarily, the master metaphor of 'altruism' projected by the corporate disclosures is ideologically at (...) odds with the more business case-oriented discourse that shapes the disclosures. This contradiction is put into starker contrast by the existence of a root metaphor, whereby the recipients of corporate philanthropy are presented as the 'deserving poor'. Synecdochal devices are present within the corporate disclosures, whereby employee initiatives that are independent of corporate strategies are used to confer attributes onto the disclosures that bolster the master metaphor of 'altruism'. As such, corporate philanthropy is presented by the paper as a structurally incoherent discourse and yet one that has implications for both extracting greater value from various societal groups and in defining, on behalf of civil society, what is a worthy cause.

There has been much discussion about what, if any, legal and moral duties professionals have to disclose relevant genetic information to the family members of someone with an identified disease predisposing mutation. Here, we present a case report where dissemination of such a genetic test result did not take place within a family. In contrast to previous literature, there appeared to be no deliberate withholding of information, instead distant relatives were unable to communicate relevant information appropriately. When communication was facilitated (...) through the follow-up of a chance remark, the patient was able to avoid planned major surgery, with its attendant morbidity, and her high anxiety levels were much reduced. We believe this case highlights the need for an ongoing debate on how genetic services can best support patients and their families with disclosing relevant genetic information to other family members.

Nearly everyone has wronged another. Who among us has not longed to be forgiven? Who has not struggled to forgive? Charles Griswold has written the first comprehensive philosophical book on forgiveness in both its interpersonal and political contexts, as well as its relation to reconciliation. Having examined the place of forgiveness in ancient philosophy and in modern thought, he discusses what forgiveness is, what conditions the parties to it must meet, its relation to revenge and hatred, when it is (...) permissible and whether it is obligatory, and why it is a virtue. Griswold argues that forgiveness is inappropriate in politics, and analyzes the nature and limits of political apology with reference to historical examples. The book concludes with an examination of the relation between memory, narrative, and truth. (shrink)

In Part 1, I contend (using Coriolanus as my mouthpiece) that Keeley and Clarke have failed to show that there is anything intellectually suspect about conspiracy theories per se. Conspiracy theorists need not commit the ‘fundamental attribution error’ there is no reason to suppose that all or most conspiracy theories constitute the cores of degenerating research programs, nor does situationism - a dubious doctrine in itself - lend any support to a systematic skepticism about conspiracy theories. In Part 2. I (...) argue (in propria persona) that the idea that there is something suspect about conspiracy theories is one of the most dangerous and idiotic superstitions to disgrace our political culture.

The publication of Darwin's On the Origin of Species in 1859 ignited a public storm he neither wanted nor enjoyed. Having offered his book as a contribution to science, Darwin discovered to his dismay that it was received as an affront by many scientists and as a sacrilege by clergy and Christian citizens. To answer the criticism that his theory was a theory only, and a wild one at that, he published two volumes in 1868 to demonstrate that evolution was (...) obvious to anyone who cared to look at a bull in a pasture or a dog on a hearth. In response to those who insisted that species were distinct since creation, Darwin pointed to breeders of pigs and pigeons. In reply to those who protested that human intervention is one thing and natural selection another, he argued, "If organic beings had not possessed an inherent tendency to vary, man could have done nothing." To counter those who scorned his descriptions of species in exotic places, he submitted local evidence of cabbages and cauliflower. Based on a wide array of sources, from ancient pictographs to Polish roosters, from skins and from skeletons, from scientific journals and breeding manuals, Darwin assembled a mass of proof--and a hypothesis about species reversion that risked his reputation anew. The Variation of Animals and Plants under Domestication is a two-volume compilation of his thorough and intensive research and the revolutionary conclusions that resulted. The first portion of his work is dedicated to a meticulous analysis of various aspects of plant and animal life, including an inventory of varieties and their physical and behavioral characteristics, investigation of the impact of a species' surrounding environment and the role that both natural and forced changes in this environment have had. Darwin then turns to a richly detailed discussion of the roles of inheritance and crossing in the development of species. A wealth of illustrations further support and enhance his findings. This fascinating, invaluable, and courageous undertaking eventually formed the foundation for our current understanding of evolution. "In science as in politics the victors tend to write the history books. As a result, the record of the past is edited, intentionally or unintentionally, so that it focuses mainly on the precursors of contemporary orthodoxy. Such a focus may accurately represent the genealogy of modern ideas, but it almost inevitably misrepresents the historical experience of their progenitors... Even the powerful, persuasive, and ultimately triumphant theory of evolution by natural selection required not only defense, but repeated buttressing and revision. Variation showed Darwin hard at work on this rearguard action, using the materials he had at hand... His information was gleaned from the observations of fanciers, breeders, and amateur naturalists, as well as from the treatises of those on the cutting edge of zoology and botany. As hindsight narrows the historical spotlight, it imposes its own sense of hierarchy on the preoccupations of the past. But Darwin was interested in all of these topics, valued all of these sources, and belonged, to a greater or lesser extent, to all of these communities."--from the Introduction. (shrink)
