Since the discovery of the double helical structure of DNA, the standard account of the inheritance of features has been in terms of DNA-copying and DNA-transmission. This theory is just a version of the old theory according to which the inheritance of features is explained by the transfer at conception of some developmentally privileged material from parents to offspring. This paper does the following things: (1) it explains what the inheritance of features is; (2) it explains (...) how the DNA-centric theory emerged; (3) it clarifies the relation between the DNA-centric theory and the ‘unfolding’ theory of development; (4) it argues that (given what we now know about developmental processes and genetic activity) the DNA-centric theory should be abandoned in favour of a pluralistic (but not holistic) theory of the inheritance of features. According to this pluralistic theory, the reliable reoccurrence of phenotypes must be explained by appealing not only to processes responsible for the reliable reoccurrence of genetic developmental factors but also to processes responsible for the reliable reoccurrence (or persistence) of nongenetic developmental factors.

The Critique of Practical Reason is traditionally regarded as one of Kant’s central works on practical philosophy. Its structural and stylistic parallels with the Critique of Pure Reason sustain one’s conviction about its fundamental systematic relevance in Kant’s ethics. Nevertheless, the compositional sketch of the system of critical philosophy in the first Critique does not presume any separate critique of reason in its practical use. This inspires to investigate the question of the sense and aim of the critique of practical (...) reason in Kant’s main works of the 1780s. Such an investigation discovers, that the concept of such a critique emerges in Kant’s Groundwork for the Metaphysics of Morals, which intends to find and to establish the supreme principle of pure morals, to supply its full-value deduction and insofar to present a sufficient introduction to the system of moral metaphysics. It is for the purpose of such a deduction, which demonstrates the normative validity and truth of categorical imperatives, that Kant considers a transition to a critique of practical reason necessary. And yet this transition as well as this critique are presumed to take place within the subject field of the Groundwork itself: the main features of the practical critique of reason as described in the Groundwork III are, according to Kant, sufficient for the purpose of justification of critical morality. If, however, the deduction of the moral law given in Groundwork III should fail, no possible future “progress of metaphysics” could compensate this failure, - because this deduction occurs at the «extreme boundary of all practical philosophy”, beyond which lies the realm of moral faith. Kant scholars consider the concepts of the “fact of pure reason” and the doctrine of the highest derivative good as crucial innovations of the second “Critique”. There are however reasons enough to dispute the question as to whether both doctrines really make for an innovation - and for an advance. (shrink)

Infant facial characteristics may affect discriminative parental solicitude because they convey information about the health of the offspring. We examined the effect of Fetal Alcohol Syndrome (FAS) infant facial characteristics on hypothetical adoption preferences, ratings of attractiveness, and ratings of health. As expected, potential parents were more likely to adopt “normal” infants, and they rated the FAS infants as less attractive and less healthy. Cuteness/attractiveness was the best predictor of adoption likelihood.

The use of reproductive techniques and the eventual reproductive negligence from the provider of reproductive services gave rise to situations in which the intended parents are deprived of raising a child genetically connected to them. Courts have been dealing with cases of those for years, but have systemically denied claimants compensation, failing to recognise as damage the loss of genetic connection. In 2017, for the first time, the Singapore High Court provided compensation for that damage, labelled “loss of genetic affinity”. (...) This paper will argue that the damage in question is the loss of genetic connection and results from a violation of reproductive rights because a key element of reproductive rights is to have children with whom we keep a genetic bond and raise them. The paper will explain why the arguments classically argued against such compensation are unfounded and it will argue for a compensation covering both patrimonial and non-patrimonial damages.

During human evolutionary history, there were “trade-offs” between expending time and energy on child-rearing and mating, so both men and women evolved conditional mating strategies guided by cues signaling the circumstances. Many short-term matings might be successful for some men; others might try to find and keep a single mate, investing their effort in rearing her offspring. Recent evidence suggests that men with features signaling genetic benefits to offspring should be preferred by women as short-term mates, but (...) there are trade-offs between a mate's genetic fitness and his willingness to help in child-rearing. It is these circumstances and the cues that signal them that underlie the variation in short- and long-term mating strategies between and within the sexes. Key Words: conditional strategies; evolutionary psychology; fluctuating asymmetry; mating; reproductive strategies; sexual selection. (shrink)

The world-view to which the long arc of modern philosophy since Descartes bends is Materialism With A Bad Conscience, a Materialism continually bedeviled by the need to deal with apparently irreducible mental items. I believe this world-view to be the offspring of an introjective error; in effect, the mentalization of sensible form, finality and value. Hence the characteristic modernist accusation is that when we take sensible form, finality and value to be genuine features of the manifest we are (...) thereby "projecting" aspects of our mental life onto an environment devoid of these features. David Hume went furthest in this Projectivist direction arguing that indeed even the very notion of an efficient cause was a projection of our habitual expectations that the regularly observed consequences of certain classes of events would continue. So far from these expectations constituting a practical knowledge of efficient causes, acquired over immense periods of time in the life of our species as it adapted to and with its complex causal environment, those expectations are merely appearances which we mistake for a mind-independent relation among the things themselves. Thus the manifest is traded in for the "manifest image of the world," an image interposed between a subject and deracinated environment. (shrink)

Elliott Sober and his defenders think of selection, drift, mutation, and migration as distinct evolutionary forces. This paper exposes an ambiguity in Sober's account of the force of selection: sometimes he appears to equate the force of selection with variation in fitness, sometimes with ‘selection for properties’. Sober's own account of fitness as a property analogous to life-expectancy shows how the two conceptions come apart. Cases where there is selection against variance in offspring number also show that selection and (...) drift cannot be distinguished in the way Sober hopes for. These issues have significance beyond the parochial matter of the coherence of Sober's system. There is no good principled answer to the question of which features of a population should count among the contributors to fitness. This means there is no non-arbitrary account of the nature of selection. (shrink)

Showing that the arithmetic mean number of offspring for a trait type often fails to be a predictive measure of fitness was a welcome correction to the philosophical literature on fitness. While the higher mathematical moments of a probability-weighted offspring distribution can influence fitness measurement in distinct ways, the geometric mean number of offspring is commonly singled out as the most appropriate measure. For it is well-suited to a compounding process and is sensitive to variance in (...) class='Hi'>offspring number. The geometric mean thus proves to be a predictively efficacious measure of fitness in examples featuring discrete generations and within- or between-generation variance in offspring output. Unfortunately, this advance has subsequently led some to conclude that the arithmetic mean is never a good measure of fitness and that the geometric mean should accordingly be the default measure of fitness. We show not only that the arithmetic mean is a perfectly reasonable measure of fitness so long as one is clear about what it refers to, but also that it functions as a more general measure when properly interpreted. It must suffice as a measure of fitness in any case where the geometric mean has been effectively deployed as a measure. We conclude with a discussion about why the mathematical equivalence we highlight cannot be dismissed as merely of mathematical interest. (shrink)

It is hypothesized that human faces judged to be attractive by people possess two features—averageness and symmetry—that promoted adaptive mate selection in human evolutionary history by way of production of offspring with parasite resistance. Facial composites made by combining individual faces are judged to be attractive, and more attractive than the majority of individual faces. The composites possess both symmetry and averageness of features. Facial averageness may reflect high individual protein heterozygosity and thus an array of proteins (...) to which parasites must adapt. Heterozygosity may be an important defense of long-lived hosts against parasites when it occurs in portions of the genome that do not code for the essential features of complex adaptations. In this case heterozygosity can create a hostile microenvironment for parasites without disrupting adaptation. Facial bilateral symmetry is hypothesized to affect positive beauty judgments because symmetry is a certification of overall phenotypic quality and developmental health, which may be importantly influenced by parasites. Certain secondary sexual traits are influenced by testosterone, a hormone that reduces immunocompetence. Symmetry and size of the secondary sexual traits of the face (e.g., cheek bones) are expected to correlate positively and advertise immunocompetence honestly and therefore to affect positive beauty judgments. Facial attractiveness is predicted to correlate with attractive, nonfacial secondary sexual traits; other predictions from the view that parasite-driven selection led to the evolution of psychological adaptations of human beauty perception are discussed. The view that human physical attractiveness and judgments about human physical attractiveness evolved in the context of parasite-driven selection leads to the hypothesis that both adults and children have a species-typical adaptation to the problem of identifying and favoring healthy individuals and avoiding parasite-susceptible individuals. It is proposed that this adaptation guides human decisions about nepotism and reciprocity in relation to physical attractiveness. (shrink)

How do adults get the right to parent a child? In this paper, I argue for a broadly Kantian account called “Parental Independence.” In short, Parental Independence says that when citizens set out to raise their offspring, they exercise their equal freedom to set and pursue their ends. Insofar as their pursuit of the end of parenthood avoids the domination of others, they are entitled to raise their offspring. The distinctive feature of Parental Independence is that it is (...) neither a dual-interest nor a child-centered account of the right to parent, but is instead grounded in a commitment to Independence.

Our objective is to test an optimality model of human fertility that specifies the behavioral requirements for fitness maximization in order (a) to determine whether current behavior does maximize fitness and, if not, (b) to use the specific nature of the behavioral deviations from fitness maximization towards the development of models of evolved proximate mechanisms that may have maximized fitness in the past but lead to deviations under present conditions. To test the model we use data from a representative sample (...) of 7,107 men living in Albuquerque, New Mexico, between 1990 and 1993. The model we test proposes that low fertility in modern settings maximizes number of grandchildren as a result of a trade-off between parental fertility and next generation fertility. Results do not show the optimization, although the data do reveal a trade-off between parental fertility and offspring education and income.We propose that two characteristics of modern economies have led to a period of sustained fertility reduction and to a corresponding lack of association between income and fertility. The first is the direct link between costs of investment and wage rates due to the forces of supply and demand for labor in competitive economies. The second is the increasing emphasis on cumulative knowledge, skills, and technologies in the production of resources. Together they produce historically novel conditions. These two features of modern economies may interact with evolved psychological and physiological mechanisms governing fertility and parental investment to produce behavior that maximizes the economic productivity of lineages at the expense of fitness. If cognitive processes evolved to track diminishing returns to parental investment and if physiological processes evolved to regulate fertility in response to nutritional state and patterns of breast feeding, we might expect non-adaptive responses when returns from parental investment do not diminish until extremely high levels are reached. With high economic payoffs from parental investment, people have begun to exercise cognitive regulation of fertility through contraception and family planning practices. Those cognitive processes maynot have evolved to handle fitness trade-offs between fertility and parental investment. (shrink)

Biologists are nearing the creation of the first fully synthetic eukaryotic genome. Does this mean that we still soon be able to create genomes that are parts of an existing genetic lineage? If so, it might be possible to bring back extinct species. But do genomes that are synthetically assembled, no matter how similar they are to native genomes, really belong to the genetic lineage on which they were modelled? This article will argue that they are situated within the same (...) genetic lineage. To see why requires closely examining whether material overlap between parents and offspring is a necessary feature of biological reproduction. The processes used to create synthetic genomes shows that these processes are a form of scaffolded reproduction because they use external machinery and take ownership of the material parts used to create synthetic genomes. Closely examining these processes also reveals, surprisingly, that ‘synthetic reproduction’ can take place between entities that don’t participate in the same biological lineages. 1Introduction2The Argument for Lineage-less Genomes3Synthetic Eukaryotic Chromosomes and Material Overlap4Biological Reproduction, Material, and Information5Synthetic Reproductive Processes and Their Implications.

Familiar summaries of evolution by natural selection hold that one requirement for change of this kind is heredity. Parents must resemble their offspring; like must beget like. However, many life cycles feature long and complex chains in which like begets unlike, before they return to their starting point. Such life cycles are common, being seen in various plants, animals, fungi, and protists. In response to these cases, the chapter offers a framework in which the familiar notion of reproduction is (...) treated as a special case of a broader category. (shrink)

Do biological relations ground responsibilities between biological fathers and their offspring? Few think biological relations ground either necessary or sufficient conditions for responsibility. Nevertheless, many think biological relations ground responsibility at least partially. Various scenarios, such as cases concerning the responsibilities of sperm donors, have been used to argue in favor of biological relations as partially grounding responsibilities. In this article, I seek to undermine the temptation to explain sperm donor scenarios via biological relations by appealing to an overlooked (...) feature of such scenarios. More specifically, I argue that sperm donor scenarios may be better explained by considering the unique abilities of agents involved. Appealing to unique ability does not eliminate the possibility of biological relations providing some explanation for perceived responsibilities on the part of biological fathers. However, since it is unclear exactly why biological relations are supposed to ground responsibility in the first place, and rather clear why unique ability grounds responsibility in those scenarios where it is exhibited, the burden of proof seems shifted to those advocating biological relations as grounds of responsibility to provide an explanation. Since this seems unlikely, I conclude it is best to avoid appealing to biological relations as providing grounds for responsibility. (shrink)

Cases of non-traditional family-making offer a rich seam for thinking about normative parenthood. Gamete donors are genetically related to the resulting offspring but are not thought to be normative parents. Gestational surrogates are also typically not thought to be normative parents, despite having gestated a child. Adoptive parents are typically thought to be normative parents even though they are neither genetically nor gestationally related to their child. Philosophers have paid attention to these kinds of cases. But they have not (...) paid attention to what the people who have engaged in these forms of family-making have to say about what they’re doing and, more specifically, how they answer the questions: “Who is the normative parent? And why?” Paying attention to their answers reveals two things. First, accounts of parenthood from people involved in two forms of non-traditional family-making – reproduction with gestational surrogacy and reproduction with donated eggs – are mutually inconsistent. This is not surprising. What is surprising is that the contradictory aspects of the views evince a common commitment to, as I shall put it, naturalizing parenthood. The central goal of this paper is to explain what that means, but rough idea is that in naturalizing parenthood, prospective parents aim to put the features that make someone a normative parent beyond the reach of human agency. I conclude by briefly suggesting that we should think of the grounds of normative parenthood – and the very task of theorizing about the grounds of normative parenthood – in a way that avoids the need to naturalize altogether.

Given that they are chance events, there can be no scientific demonstration or knowledge of monsters. There are still, however, many recognizable elements of scientific explanation in Aristotle's Generation of Animals Book IV chapter 4. What happens in cases of monsters and deformities occurs in the process of generation, and there is much that we can know scientifically about this process—working from the animal’s essential attributes outward to factors that influence these processes. In particular, we find Aristotle looking for and (...) investigating whether “for the most part” (FMP) correlations are causally relevant and linked to essence. Even though the birth of monsters is scientifically inexplicable, the features of animals that tend to produce them can be known about. I will explain how it is that producing more than one offspring per birth is a knowable feature of a kind. This feature, along with others, can then give us a much better grasp on what happens in particular instances of monstrous birth. (shrink)

Understanding good design requires addressing the question of what units undergo natural selection, thereby becoming adapted. There is, therefore, a natural connection between the formal Darwinism project (which aims to connect population genetics with the evolution of design and fitness maximization) and levels of selection issues. We argue that the formal Darwinism project offers contradictory and confusing lines of thinking concerning level(s) of selection. The project favors multicellular organisms over both the lower (cell) and higher (social group) levels as the (...) level of adaptation. Grafen offers four reasons for giving such special status to multicellular organisms: (1) they lack appreciable within-organism cell selection, (2) they have multiple features that appear contrived for the same purpose, (3) they possess a set of phenotypes, and (4) they leave offspring according to their phenotypes. We discuss why these rationales are not compelling and suggest that a more even-handed approach, in which multicellular organisms are not assumed to have special status, would be desirable for a project that aims to make progress on the foundations of evolutionary theory.

While it is generally agreed that the concept of homology refers to individuated traits that have been inherited from common ancestry, we still lack an adequate account of trait individuation or inheritance. Here I propose that we utilize a counterfactual criterion of causation to link each trait with a developmental-causal (DC) gene. A DC gene is made up of the genetic information (which might or might not be physically contiguous in the genome) that is needed for the production of the (...) organismic attributes that comprise the trait. I argue that individuated traits—phenes—correspond to organismic features that are caused by DC genes. Using such an approach, we can define a DC map, which shows the relations between each pair of phenes and provides a succinct summary of genotype-phenotype relationships and phenotypic complexity. Phenes in parents and offspring are judged to be homologous if their DC genes are composed of orthologous genetic factors. When comparing more distantly related organisms, traits are homologous when linked by a chain of parent-offspring homologs along the path of ancestry that links the two organisms. There are three possible ways to deal with the potential for multiple equivalent DC genes: maximal, minimal, and consensus homology. Whereas maximal homology has limited utility, the other two approaches have value and can help to guide research at the intersection of evolution and development. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Male Reproductive Strategies in Sherwood Anderson's "The Untold Lie"Judith P. SaundersSingled out repeatedly as one of the finest stories in Sherwood Anderson's Winesburg, Ohio, "The Untold Lie" (1919) has attracted surprisingly little sustained critical comment.1 Like all the stories in the Winesburg cycle, this one delineates a revelatory moment of inner turmoil. There is little outward action; conflict and suspense are generated chiefly in the interior of the protagonist's (...) psyche, focusing on his ambivalence as husband and father. Readers become privy to "the buried life" of unacknowledged impulses and the "hidden truth" of repressed resentments,2 as Anderson's central characters struggle with the antithetical "choices available to the individual as biology works its will."3 A portrait of the male mind deliberating the relative advantages of alternative reproductive strategies, the story notably repays biosocial investigation. The theoretical framework, as well as the intellectual rationale, for undertaking biosocial investigation of literary texts has been explained ably by critics and aestheticians such as Joseph Carroll, Brett Cooke, Ellen Dissanayake, Robert Story, and others. Readers unfamiliar with the historical and theoretical foundations of Darwinian literary criticism will find useful commentary in works by these and other thinkers in this rapidly growing field.4Anderson concentrates on the interactions between two men at different stages in life, one middle-aged, perhaps fifty, and one youthful, "only twenty-two."5 The older man, Ray Pearson, has made his most important reproductive decisions well before the story begins: he has been married for many years and fathered half a dozen children (p. 203). He works as a farm hand, eking out a meagre living for his family by means of hard physical labor. A few details are sufficient to suggest [End Page 311] his poverty: his house is "tumble-down," his children "thin-legged," his coat torn and shiny with age (pp. 203, 206). Ray's wife, "sharp" in both features and voice, appears to be a perpetually anxious scold, concerned with fundamental problems of family subsistence. Ray's direct fitness (as measured by reproductive success) promises to be respectable, but the task of rearing his numerous offspring to adulthood has required and will continue to require his utmost effort and full-time commitment. He is just barely able to support his family (food is being purchased on a day-by-day basis), and there is little margin of safety in his situation.As foil to Ray, Anderson presents Hal Winters, a man not only younger but different in physique, in temperament, and in social class. Hal is big, tall, and broad shouldered; by way of contrast, Ray's shoulders are described as "rounded by too much and too hard labor," and he is "almost a foot shorter" than the robust Hal (p. 203ff). Inclined to prototypical masculine display, Hal is observed "roistering" about the town at night, dressing in "cheap flashy clothes." He challenges his own father in a fist fight, and as a result he is arrested and jailed. His brash and often reckless behavior is very unlike that of the "quiet, nervous," and "altogether serious" Ray. In the community Hal has the reputation of "a bad one." A fighter, a drinker, and a womanizer, he is "always up to some devilment." Unsurprisingly, Hal's family background is said not to be particularly respectable. The fathers of both Hal and Ray are small-business owners: the Winters operate a sawmill, the Pearsons a bakery. (The narrator never explains why Ray did not join or succeed his father in the bakery business, which presumably would have offered him a better income and a physically less onerous profession.) The stated difference in social standing appears to derive from the two families' differing records of conduct.Hal's aggressive propensities seem to be at least in part hereditary. He is "the worst" of three notoriously bad brothers, all sired by "a confirmed old reprobate" (pp. 202–3). The father, old Windpeter Winters, is remembered best for the gratuitous violence of his death. Drunk, he drove his team of horses along the railroad tracks straight into the path of an oncoming train, having slashed with his whip at a neighbor who... (shrink)

The problems of organismal agency and phenotypic plasticity present significant interest for modern developmental and evolutionary biology, as well as comparative and biosemiotic approaches. At the same time, the question of how behavioural and other proximal phenotypic factors may potentially drive developmental and evolutionary variation remains open, particularly in relation to life-history and allometric theory (where the issue of agency has been seldom explored). To fill these gaps, this chapter revisits the anti-entropic (negentropic) approach to ontogeny developed by I.A. Arshavsky (...) (1903–1996) and his school. Within this tradition, diverse developmental processes and organisms were studied in order to understand how biological agency and phenotypic plasticity can be interrelated and together affect the formation and integration of biological traits – including the remarkable physiological and morphological features distinguishing primarily altricial (immaturely born) from primarily precocial (maturely born) eutherians. This chapter revisits these concepts and results in the light of current research. In particular, that Arshavsky’s non-equilibrium approach may still help to frame new questions and integrative concepts is shown with respect to certain unresolved problems of metabolic scaling, including the apparent biophysical paradox of increased work capacity and bioenergetic reserves in larger/more precocial organisms. Finally, we shall also consider a novel anti-entropic hypothesis regarding possible agential origins of the prolonged gestation and reduced offspring numbers in such animals, which may have a variety of implications for current work in biology and biosemiotics.

Konrad Lorenz, an ethologist, proposed that certain physical elements are perceived as cute and induce caretaking behavior in other individuals, with the evolutionary function of enhancing offspring survival. He called these features Kindchenschema, baby schema. According to his introspection, these include a large forehead, chubby round features, and chubby cheeks. Previous studies are limited to examining the effects of these facial features on perceived cuteness. However, other morphological factors may be related to perceived cuteness. This study (...) uses Bayesian optimization, one of the global sequential optimization methods for estimating unknown functions, to search for facial morphological features that enhance the perceptions of facial cuteness. We applied Bayesian optimization incorporating Gaussian process ordinal regression, which allows an estimation of the latent cuteness function based on evaluations using the Likert scale. A total of 96 preschool children provided the facial images used in this study. We summarized the facial shape variations using methodologies of geometric morphometrics and principal component analysis up to the third principal component, which we refer to as the face space. A total of 40 participants evaluated the images created by warping the average facial texture of the children's faces with randomly generated parameters in the face space. Facial traits related to perceived cuteness were estimated based on the averaged cuteness function. Perceived cuteness was linked to the relative lower position of facial components and narrower jawline but not to the forehead height. (shrink)

The aim of the social and behavioral sciences is to understand human behavior across a wide array of contexts. Our theories often make sweeping claims about human nature, assuming that our ancestors or offspring will be prone to the same biases and preferences. Yet we gloss over the fact that our research is often based in a single temporal context with a limited set of stimuli. Political and moral psychology are domains in which the context and stimuli are likely (...) to matter a great deal (Van Bavel, Mende-Siedlecki, Brady, & Reinero, 2016). In response to Yarkoni (see BBS issue), we delve into topics related to political and moral psychology that likely depend on features of the research. These topics include understanding differences between liberals and conservatives, when people are willing to sacrifice someone to save others, the behavior of political leaders, and the dynamics of intergroup conflict.

In “Where Is the Sin in Synecdoche?” (2005) Adrienne Asch and David Wasserman criticize the choice to use prenatal testing (PNT) to determine disability. Notwithstanding the multiple meanings, motives, and circumstances behind people’s reproductive choices, Asch and Wasserman argue that individual choices to reject impaired potential offspring should be the subject of moral scrutiny, since they are likely to be the result of synecdoche—“the uncritical reliance on a stigma-driven inference from a single feature to a whole future life” (181). (...) Such synecdochal choices, they argue, assume that in virtue of impairment, the future child in question would be “incapable of [the] intimacy and community” involved in family.. (shrink)

The placenta arose during mammalian evolution, which is recent in evolutionary terms. Genetic changes underlying placental development remain identifiable by the new science of comparative genomics (approximately post‐2000). Randomly arising features of genomes including endogenous retroviruses and transposable elements have provided structural genes and gene‐regulatory motifs responsible for innovations in placental biology. Stochastic genetic events indeed contribute to new functionality. Theologically, random mutations are part of the strategy by which the divine purpose for humanity is attained. Placental function critically (...) underlies human brain development, and suboptimal function, associated with environmental conditions and maternal distress, contributes to mental health deficits in the offspring. Many enter life with handicaps arising from contingent events in utero, mandating understanding, compassion, and socioemotional support, imperatives native to moral including biblical values. The extended period of development afforded by placentation enables prenatal parenting, with implications for sensitive and devoted parental commitment. (shrink)

The paper demonstrates that the biological species concept that Mayr con- trasts with the typological one in fact presupposes a version of the typological species concept.

Purpose. Aging is intricate process of self-transformation in view of involution of body, loss of sexual attractiveness, but at the same time, old age is a time for reconsideration of self-existence in time and in the world within coherence of life sense targets and their realization. Unique individual experience of growing old implemented in Ukrainian literature can complete the data received by gerontology. Moreover gender approach in literary gerontology highlights masculine / feminine phenotypical features of internal reverberating of aging. (...) Theoretical basis. To inquire into existential and psychological problems of aging exemplified in the twentieth-century Ukrainian Lyrics it is seems to be the most effective to employ philosophical and psychological approaches in gerontology, as well as feministic studies on elder female body discrimination, in particular in literature. Originality. This research paves the way to the development of gender and literary dimensions in Ukrainian gerontology and anthropology in general. Some of the existential and psychological problems of aging are revealed on the material of 20th-century Ukrainian poetry. The individual lyric experience of aging in different gender moods is anchored mostly in psychic, mental, sense-life strategies. Conclusions. Among the feminine strategies of aging self-reception there are observation of own elder body with anxiety and fear, its "invisibility", deepened feelings of loneliness, self-estrangement, but also finding the sense of life and soul harmony in own family, offspring. Masculine self-reception of aging deals with ideal spiritual model of Wise old man – more abstract than personal; masculine anxiety is caused by physical bodily declining, not attractiveness, but strength and power loosing.

Biologically inspired Evolution Algorithms, that use individuals as searching points and progress search by evolutions or adaptations of the individuals, are widely applied to many optimization problems. Many real world problems, which could be transformed to optimization problems, are very often difficult because the problems have complex landscapes that are multimodal, epistatic and having strong local minima. Current real-coded genetic algorithms could solve high-dimensional multimodal functions, but could not solve strong deceptive functions. Niching GAs are applied to low-dimensional multimodal functions (...) by maintaining diversity of searching population, but could not be applicable to highdimensional functions. In order to optimize high dimensional deceptive multimodal functions, we propose a new EA called Adaptive Neighboring Search, that is structured with a selection for reproduction by restricting mating individuals to neighbors, a crossover-like mutation using the mating individuals and an elitist selection for survival within one centered parent and its offsprings. By individualized generation alternation and complementary crossover-like mutation, the ANS realizes self-distributive and locally adaptive search, and individuals in the search divide into plural promising valleys and converge within same valley. The ANS is applicable to high dimensional deceptive multimodal function optimization, because the feature is independent of number of problem’s dimensions. By applying to high dimensional Fletcher and Powell function as a deceptive multimodal one, we show the ANS can obtain various solutions and several optimal solutions in high probability. (shrink)

Secondary lymphoid organs form in utero through an inherited and well‐established developmental program. However, maternal non‐heritable features can have a major impact on the gene expression of the embryo, hence influencing the future health of the offspring. Recently, maternal retinoids were shown to regulate the formation of immune structures, shedding light on the role of maternal nutrition in the genetic signature of emergent immune cells. Here we highlight evidence showing how the maternal diet influences the establishment of the (...) immune system, and we also discuss how unbalanced maternal diets may set the response to infection and vaccination in the progeny.

Generation and heredity theories before early modern mechanist accounts might be faulted for numerous deficits. One might cite in this regard the failure to even attempt to explain how the inheritance of traits could occur, given what is known about the generation of new individuals. On the other hand, it would be hard to allow this as a true failure against the backdrop of a generation theory that poses form, and not matter, as the key to understanding the emergence of (...) new structures in the offspring of two organisms. Hence the signal contribution of the mechanist accounts in this sphere was simply the suggestion that theories of generation and heredity might look to matter and its behavior in order to explain how new individuals are created and retain or discard features of the individuals whence they sprung. Among these accounts, one early important set of views was presented by Pierre Gassendi, eventually as a full-blown atomist conjecture but even beforehand, and early on, as a thoroughgoing materialist theory. Gassendi's materialist mechanism for the transmission of traits is imperfect (and by the common sense of our day, implausible), not always or exclusively deployed in generation, and not clearly the physical bearer of information, as conformity to a materialist model would suggest. Nonetheless, his proposed mechanism represents a valuable attempt to provide an account of inheritance phenomena in materialist and ultimately atomist terms and rooted in an account of generation.

In lieu of an abstract, here is a brief excerpt of the content:Hereditary Eloquence Among the Torquati: Catullus 61.209–18S. J. HarrisonTorquatus volo parvulus matris e gremio suae porrigens teneras manus dulce rideat ad patrem semihiante labello.sit suo similis patri Manlio et facile omnibus noscitetur ab insciis et pudicitiam suae matris indicet ore. 1At the close of Catullus’ lyric epithalamium for a Manlius Torquatus, the speaker of the poem wishes for children from the marriage, a standard epithalamial topic in this position; (...) the wish for features in the final prayers of the wedding-speech according to Menander Rhetor (II.411.16, 20–21 Spengel). One interpretational problem here is that lines 215–18 seem to say the same thing twice—a double wish that the son of the marriage be easily recognisable through his physical features as the true offspring of his father. This problem can be solved by a closer consideration of the text and of the identity of the Manlius Torquatus involved.There seems to be general agreement that the most likely candidate for the bridegroom of Catullus’ poem is L. Manlius Torquatus, praetor in 50 or 49 B.C. and killed in the civil war in 47. 2 Cicero knew and admired this Torquatus, making him the Epicurean spokesman in the De Finibus, and giving him a fulsome notice in the Brutus (265). It is clear from the latter that this Torquatus was a leading public speaker of his time: Cicero speaks of his divina memoria, summa verborum et gravitas et elegantia. My contention is that this detail of Torquatus’ eloquence makes sense of Catullus 61.209–18. [End Page 285]The shape of the sentence seems to be as follows: the general idea that the son will resemble his father is put first (sit suo similis patri / Manlio), and then subdivided into two particular elements balanced and linked by et... et. In the usual interpretation, those two elements are identical—Manlius’ son will be easily recognised as his by all through family physical resemblance (ore). This seems unsatisfactory, given the apparent care taken to balance and differentiate them. But if we translate ore not as ‘face’ but as ‘mouth’, i.e., eloquence, a new and appropriate point emerges which is different from that of physical resemblance: as the son of a noted orator, it will be through his hereditary talent for public speaking as well as by his looks that the future Torquatus will be proved his father’s true child. Os is found elsewhere in poetry in this pregnant sense of ‘eloquence’: we may compare Ovid, Pont. 3.5.7 iuvenis patrii non degener oris (a similar context of hereditary eloquence, addressing Cotta Maximus, son of the great orator Messalla Corvinus), Silius, Punica 11.65 cunctis praecellens Virrius ore (the rhetorical skills of a Capuan delegate), and TLL 9.2.1081.54ff.It is interesting to note from two famous poems of Horace that Catullus’ prophecy about the eloquence of Torquatus’ son may have been fulfilled. It has been suggested that the Manlius Torquatus addressed by Horace in Epistles 1.5 and Odes 4.7 is a son of the consul of 65, 3 and therefore perhaps contemporary with or somewhat older than Horace, born in 65 himself. However, it is equally possible that he is a son of Catullus’ bridegroom, the praetor of 50 or 49, and therefore younger than the poet. 4 We should imagine a son of the praetor Torquatus being born in the mid-50s, the approximate date of Catullus 61; this would seem appropriate for the Torquatus addressed in Epistles 1.5, a rising advocate who looks to be in mid-career around 20 B.C., and for the addressee of Odes 4.7, fittingly addressed in around 13 B.C. with thoughts on mortality now he has reached forty and middle age in Horatian terms (cf. Odes 2.4.22–24). Horace’s Torquatus is clearly a prominent orator: the [End Page 286] epistle urges him to leave the law-courts, where he is in demand as an advocate, and come to a party at Horace’s house, while Odes 4.7 refers specifically to his facundia (23). This eloquent Torquatus could be following his father... (shrink)

Electronic mail and information exchange on the World Wide Web have in recent years developed into indispensible features of scholarly activity. The speed and convenience of computer-mediated communication across the planet are rapidly changing the established patterns of academic transactions. While thousands of philosophers have begun to take advantage of e-mail, web-servers or digital text repositories, systematic exploration of the newly available technology has been lagging behind. There is, it has to be admitted, a colourful offspring of postmodern (...) writing celebrating this alleged telematic revolution. I give just one example. (shrink)

At the beginning of the twentieth century, the wild animal story emerged in Canadian literature as a distinct genre, in which animals pursue their own interestsOCosurvival for themselves, their offspring, and perhaps a mate, or the pure pleasure of their wildness. Bringing together some of the most celebrated wild animal stories, Ralph H. Lutts places them firmly in the context of heated controversies about animal intelligence and purposeful behavior. Widely regarded as entertaining and educational, the early storiesOCoby Charles G. (...) D. Roberts, Ernest Thompson Seton, John Muir, Jack London and othersOCohad an avid readership among adults and children. But some naturalists and at least one hunterOCoTheodore RooseveltOCodiscredited these writers as nature fakers, accusing them of falsely portraying animal behavior. The stories and commentaries collected here span the twentieth century. As present day animal behaviorists, psychologists, and the public attempt to sort out the meaning of what animals do and our obligations to them, Ralph Lutts maps some of the prominent features of our cultural landscape. Tales include: OCo "The Springfield Fox" by Ernest Thompson Seton OCo "The Sounding of the Call" by Jack London OCo "Stickeen" by John Muir OCo "Journey to the Sea" by Rachel Carson Other selections include esssays by Theoore Roosevelt, John Burroughs, Margaret Atwood, and Ralph H.

If humans are not capable of immortality, then eschatological doctrines of heaven and hell make little sense. On that Christians agree. But not all Christians agree on whether humans are essentially immortal. Some hold that the early church was right to borrow from the ancient Greek philosophers and to bring their sense of immortality to bear on the interpretation of biblical passages about the afterlife. Others, however, suggest that we are inherently mortal, and only conditionally immortal. This latter view is (...) usually associated with an annihilationist interpretation of the doctrine of hell and a rejection of eternal torment. In a philosophical analysis and argument, McLeod-Harrison proposes that humans are, indeed, immortal, but not essentially so. But neither are we immortal accidentally or conditionally. Instead, immortality is an enduring property--a property we cannot lose once created. McLeod-Harrison carefully delineates the sense of immortality he defends and provides a broadly Christian philosophical argument for it. The argument, if correct, leaves the recent suggestion that the unredeemed are annihilated on unsteady metaphysical feet. However, McLeod-Harrison does not defend eternal conscious punishment for the unredeemed, but suggests some ways to think about the possibility of a universal salvation. ""McLeod-Harrison provides an admirably careful metaphysical analysis of the concept of human immortality, ultimately arguing for the impossibility of personal annihilation. Whether or not one finally agrees with his thesis, this work is an immensely valuable resource, especially as regards discussions of philosophical anthropology and the doctrine of hell."" --James S. Spiegel, Professor of Philosophy and Religion, Taylor University ""In this fascinating, albeit complicated, argument against conditional immortality (annihilationism), the author makes no claim that the human soul is essentially immortal; he argues instead that, once a human offspring acquires a fully robust free will and thus becomes fully human, it is metaphysically impossible that it should cease to exist altogether. Whether or not one accepts every detail of this argument, it provides an original and intriguing twist to theological discussions of free will."" --Thomas Talbott, Professor Emeritus of Philosophy, Willamette University, Author of The Inescapable Love of God ""I often say the future of the hell debate is between conditional immortality and universal reconciliation, and it is no secret that I think the biblical case for the former is unassailable. However, while I am not persuaded by this volume's case for enduring and universal human immortality, it nevertheless promises to add precision to the language of immortality and to feature prominently in the philosophical side of that debate moving forward."" --Christopher M. Date, editor of Rethinking Hell: Readings in Evangelical Conditionalism Mark S. McLeod-Harrison is Professor of Philosophy at George Fox University. (shrink)

Contemporary Chinese society has witnessed ongoing complex institutional and cultural reconfiguration, driven by the transition from the socialist planned economy to marketization and later its deep engagement in globalization and neoliberalism. In this reshaping of Chinese society, tradition and modernity, the resurgence of patriarchal Confucian tradition, the socialist version of modernity, the capitalist version of modernity, and the socialist heritage intermingle, and all seem to define a mosaic temporality.Facing the increasing uncertainties of the market, family members in post-reform China have (...) to stick together as an economic safety net, emotional harbor and spiritual fortress. Chinese parents heavily invest in their children and continue to support them in their adulthood; whereas, the youth is under great obligation to providing old age care for their parents; and parents may regard this heavily-invested offspring as their private product. This resurgent but modified familialism, is not an exact replication of traditional familialism, but is definitely different from the family modes featured by individualism in Western contexts. Mosaic familialism is characterized by a sequential symbiosis between parents and children facing financial constraints and unforeseeable uncertainties with a lack of a social safety net. At the same time, patriarchal Confucianism is rejuvenated to a certain degree, women’s traditional wife and mother role is once again stressed, if not glorified; and the neoliberal discourse articulating personal choice and responsibility, but not individual right, stands by seamlessly. Parents and children, husband and wife are dependent on each other in the intimate family, following a clearly gendered pattern. (shrink)

Music comprises a diverse category of cognitive phenomena that likely represent both the effects of psychological adaptations that are specific to music (e.g., rhythmic entrainment) and the effects of adaptations for non-musical functions (e.g., auditory scene analysis). How did music evolve? Here, we show that prevailing views on the evolution of music – that music is a byproduct of other evolved faculties, evolved for social bonding, or evolved to signal mate quality – are incomplete or wrong. We argue instead that (...) music evolved as a credible signal in at least two contexts: coalitional interactions and infant care. Specifically, we propose that (1) the production and reception of coordinated, entrained rhythmic displays is a co-evolved system for credibly signaling coalition strength, size, and coordination ability; and (2) the production and reception of infant-directed song is a co-evolved system for credibly signaling parental attention to secondarily altricial infants. These proposals, supported by interdisciplinary evidence, suggest that basic features of music, such as melody and rhythm, result from adaptations in the proper domain of human music. The adaptations provide a foundation for the cultural evolution of music in its actual domain, yielding the diversity of musical forms and musical behaviors found worldwide. (shrink)

Preimplantation genetic diagnosis (PGD) raises serious moral questions concerning the parent-child relationship. Good parents accept their children unconditionally: they do not reject/attack them because they do not have the features they want. There is nothing wrong with treating a child as someone who can help promote some other worthwhile end, providing the child is also respected as an end in him or herself. However, if the child's presence is not valued in itself, regardless of any further benefits it brings, (...) the child is not being treated as an end in the full sense of the term. In this paper, I argue that these principles apply to human embryos, as well as to born human offspring: the human moral subject is a bodily being, whose interests and rights begin with the onset of his or her bodily life. The rights of the living, bodily human individual include a right not to be attacked/abandoned because of his or her genetic profile. PGD is harmful to the parent-child relationship, and we give mixed messages to parents by expecting them to show unconditional commitment to offspring after birth, while inviting them to take a very different approach at the prenatal stage.

Habermas's collection of essays "The Future of Human Nature" is of particular interest for two sorts of reasons. For those interested in bioethics, it contains a genuinely new set of arguments for placing serious restrictions on using prenatal genetic technologies to “enhance” offspring. And for those interested in Habermas’s moral philosophy, it contains a number of new developments in his “discourse ethics”—not the least of which is a willingness to engage in applied ethics at all. -/- The real key (...) to Habermas’s argument is that human personhood and moral agency presuppose certain modes of relating to oneself that are threatened by the asymmetrical way in which genetic enhancements would presumably work. Thus, instead of taking up and then extending familiar normative concerns about unequal opportunities or the criteria for moral personhood, Habermas believes that the emerging technologies of genetic enhancement demand genuinely new arguments, and he proposes to focus on the effects of genetic programming on whether the agent can consider herself free and equal—effects, that is, regarding what one might call the reflexive attitudinal preconditions for moral agency. -/- Like contractarians and Kantians more generally, Habermas faces difficulties accommodating the intuition that we might have obligations toward potential persons. The difficulty is particularly pronounced in the case of Habermas’s “discourse theory of morality,” since it construes the moral point of view in terms of processes of deliberation among all those affected by the norm at issue which the participants consider in the deliberative process to be open, fair, and inclusive. Future generations do not fit neatly into this deliberative process, nor do prepersonal humans. Moral norms adjudicated in such discourse clearly affect their interests, but they cannot themselves participate in the discourse. In the past, Habermas and other “discourse ethicists” have tried to address this worry by introducing “advocatory discourses.” But this move threatens to undo a distinctive, appealing feature of Habermas’s moral theory: the pragmatist insistence on the innovative, critical, unpredictable discourse generated by actual participants in discourse and the refusal (contra Rawls, in particular) to rely on hypothetical representatives. -/- In The Future of Human Nature, Habermas ventures a different strategy,focused on expanding what he calls the “ethical” domain, which differs from the “moral” domain in being a matter of a community’s articulation of its core values and conception of the good. Previously, Habermas distinguished “ethical-existential” and “ethical-political” domains, as a matter of who an individual or a community, respectively, is and wants to be. In the present book, Habermas makes the remarkable move of introducing the category of the “species-ethical,” which is supposed to be the domain of questions raised by the human species as a whole about the question of what it is to be human. This theoretical move extends further steps Habermas had already taken in speaking of ethical solidarity within the global community. -/- . (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Literature as Sheltering the HumanJohn Durham PetersLiterature as Sheltering the Human, by Frederic Will; 203 pp. Lewiston, Maine: Edwin Mellen Press, 1993, $69.95.This volume contains thirteen essays by Frederic Will, poet, critic, ex-professor of literature, autobiographer, translator, man of letters. All concern the peculiar powers of literature to offer spiritual comfort and protection against the storms of life.A cluster of four theoretical essays begins the collection. The first (...) surveys Husserl’s intellectual offspring, Merleau-Ponty, Sartre, and Heidegger, and seeks in their philosophies of language a grounding for literature’s uniqueness. The second essay argues that everyday language is always on the verge of entropy, but at its best, can be sublimated into literature. The third essay is a fiction of a crazed lit professor trying to master “the whole of literature” (p. 41). The eternally elusive object of “literature” turns out to evoke erotic-aggressive energies. The fourth essay on “Influencing the Past” rehearses some Benjaminian and Borgesian themes about literary influence being not causality, but intertextual resonance.The next set of five essays—which Will calls a “testimony” (p. 133) or “hit and run theology” (p. 138)—forms the core of the book. They treat “sheltering the human” in Homer, the Bible, Sappho, the Bhagavad Gita, and the epistles of St. Paul. Each ponders an enclosure—a retreat from battle, a womb, an act of translation, an inward wrestle of conscience, the blood of Christ—made of words. To my mind, this is the best part of the book: a steady meditation, graced with poetic lines and steeped in wide learning, on the proposition that “poetically man dwells.” Here Will performs the humane survey of world-literature he elsewhere extolls.The concluding section explores the relation of literature to the other arts. There is an essay on the gradual discovery of the oral core of Greek literature, largely through German scholarship, and one on literature’s relation to the other arts, which argues for its unique centrality among human expressive forms, thanks to its alleged continuity with the essential human possession, language. The penultimate essay meditates on Adorno’s aesthetics of music (concluding on an affirmative note not quite in tune with Adorno’s gloomy musings on capitalism), and the grand finale muses on the relation of art to life, via the dubious conceit of “art” as a great resort hotel.The book is remarkable for an intense and bald aestheticism that is exceedingly rare today. Will calls literature “the ripest offspring of language” (p. 1) and is happy to speak of masterpieces, genius, revelation, the autonomy of art, classics, humanism, values lodged in the structure of the universe (p. 125), universal validity (p. 131), “texts high in redemptive claim” (p. 147), the continuing necessity of the classical tradition (p. 190), and the artist as all but a different species (p. 200). The faith in a totality called “literature” is, to put it lightly, out of season in the academy today. As Will, a confirmed foe of [End Page 387] academic politics and pedantry, might well suggest, this may speak in its favor. Though Will’s aestheticism may refresh, I cannot help but wonder with Adorno whether some forms of expression and faith are objectively impossible in certain eras. Can “literature” sustain credulity today as anything more than one among many remarkable human practices?There is something, if I may say it, sheltered about these essays. If, as J. S. Mill said, eloquence is heard but poetry is overheard, this work is more poetry than eloquence. It features repeated and unannounced autobiographical intrusions. The self-reflexive quality supplies ready phrases to the reviewer: Will calls himself a “fallen contemporary classicist,” praises “high-minded eclecticism” and favors those thinkers who “sensualize knowing.” These traits make for a rare voice singing in the cornfields of Iowa.John Durham PetersUniversity of IowaCopyright © 1995 The Johns Hopkins University Press...

This chapter begins with a brief review of the theory of parent-offspring conflict and considers the role of this conflict in the cognitive development of human infants. It then discusses the evolution of theory of mind — which is taken to have its origins in human evolution — and considers how this human cognitive specialization might have interacted with existing parent-offspring dynamics. How the epigenetic systems of infants might have responded is shown by elaborating upon existing cognitive and (...) behavioural systems, or by canalizing later developing ones earlier into development, in order to recruit higher degrees of parental investment. The merits of this framework is assessed in the context of the development of behaviours considered by some researchers to be indicative of a certain degree of social understanding, namely, gaze-following, pointing, social smiling, and neonatal imitation. The chapter concludes by showing how this proposal makes several longstanding theoretical and methodological difficulties for the field of cognitive development even more vexing. (shrink)

Data on birth order and parent-offspring relations for 1,601 adolescents participating in the National Longitudinal Study of Adolescent Health were used to test hypotheses about the role of adolescent suicidal behavior in parent-offspring conflict. Among adolescents highly dissatisfied with their mothers, the odds that middleborns would make at least one suicide attempt was 23% that of first- and lastborns (p<.001), but their odds of receiving medical treatment for their attempts was 8.5 times greater than the odds for first- (...) and lastborns (p=.032). The results are tentatively interpreted as supporting the hypothesis that adolescents use suicide attempts to leverage investment from their parents. (shrink)

Can mammalian mothers adaptively control the sex of their offspring? The influential Trivers-Willard hypothesis proposes that when maternal condition increases the fitness of sons more than that of daughters, the proportion of sons produced should increase with maternal condition. Studies of mammals, however, often fail to support this hypothesis. This article highlights recent advances, including studies on the assumptions of the TWH and physiological mechanisms for sex-ratio manipulation. Particular emphasis is placed on how factors such as paternal quality, maternal (...) reproductive costs and environmental conditions experienced by mothers early in life can mask/alter the expected relationship between maternal condition and offspring sex ratio or lead to apparent support for the TWH. While there is growing evidence that sex ratio around conception may be maternally and paternally manipulated, a challenge for future studies on sex allocation is to integrate how multiple and potentially opposite selective pressures affect offspring sex ratio. The relationship between offspring sex and maternal condition lies at the heart of one of the most controversial hypotheses in evolutionary biology. This review highlights recent findings on the Trivers-Willard hypothesis with particular emphasis on factors which may mask the relationship of interest or falsely demonstrate it. (shrink)

Lactation constitutes a major focus for research in international health because of its dramatic impact on child survival; evolutionary biology has investigated lactation as an important aspect of parenting strategy, with implications for understanding parent-offspring conflict. These perspectives are brought together in an attempt to develop integrated models for an issue of key international health concern: the duration of exclusive breast-feeding and the timing of weaning. This analysis highlights the relevance of evolutionary theory for practical problems in public health, (...) and it suggests the utility of public health outcomes for addressing evolutionary questions.

Adolescence signifies a transition from the use of prereproductive to reproductive strategies in the life history of Homo sapiens. Insofar as human generations overlap, events at adolescence, surrounding the onset of puberty, offer a unique glimpse into human adaptation from the point of view of the changing strategies of both parents and offspring. The timing of puberty is an important life history trait that varies between species, but also between and within the sexes in human beings. The onset of (...) puberty marks the beginning of the reproductive life, is affected by previous experience, and serves as a trigger for behavioral change. Surbey (1988, 1990) reported relationships between father absence, heightened levels of childhood stress, and early menarche and considered them within the context of human evolutionary history. Subsequently, similar findings have been reported in a number of human populations and have been interpreted from several evolutionary perspectives. This article discusses the extent to which these and related findings regarding alterations in the timing of human puberty reflect evolved parental or offspring strategies. It entails a consideration of the applicability of the concepts of phenotypic plasticity, nonadaptive genetic variation, and conditional and alternative reproductive strategies in describing the interwoven nature of strategies employed by parent and child in the transition at adolescence.

Durkheim's functional and structural sociology is examined with an eye to the two structuralist modes of inquiry that it inspired, French structuralism and British structuralism. French structuralism comes from Levi-Strauss's inverting the basic ideas of Durkheim and others in the French circle, including Marcell Mauss, Robert Hertz, and Ferdinand de Saussure. British structuralism comes from A.R. Radcliffe-Brown's adoption of Durkheimian ideas to ethnographic interpretation and theoretical speculation. French structuralism produced a broad intellectual movement, whereas British structuralism culminated in network analysis, (...) which is beginning only now to become a broad intellectual movement. In both cases, the intellectual children and grandchildren of functionalism may prove to be more influential in sociology and elsewhere than Durkheimian functionalism, the parent. (shrink)
