Although largely conceptual, the book is an unequivocal defense of this new theory in the explanation of human behavior.

This is an introductory article on sociobiology, particularly its relationship to eugenics. Sociobiology developed in the 1960s as a field within evolutionary biology to explain human social traits and behaviours. Although sociobiology has few direct connections to eugenics, it shares eugenics’ optimistic enthusiasm for extending biological science into the human domain, often with reckless sensationalism. Sociobiology's critics have argued that sociobiology also propagates a kind of genetic determinism and represents the zealous misapplication of science beyond (...) its proper reach that characterized the eugenics movement. More recently, evolutionary psychology represents a sophistication of sociobiology that attends to the mind as the "missing link" between evolution and behaviour (Cosmides and Tooby 1992, Pinker 1997).

In June 1975, the distinguished Harvard entomologist Edward O. Wilson published a truly huge book entitled, Sociobiology: The New Synthesis. In this book, drawing on both fact and theory, Wilson tried to present a com prehensive overview of the rapidly growing subject of 'sociobiology', the study of the biological nature and foundations of animal behaviour, more precisely animal social behaviour. Although, as the title rather implies, Wilson was more surveying and synthesising than developing new material, he com pensated (...) by giving the most thorough and inclusive treatment possible, beginning in the animal world with the most simple of forms, and progressing via insects, lower invertebrates, mammals and primates, right up to and in cluding our own species, Homo sapiens. Initial reaction to the book was very favourable, but before the year was out it came under withering attack from a group of radical scientists in the Boston area, who styled themselves 'The Science for the People Sociobiology Study Group'. Criticism, of course, is what every academic gets (and needs!); but, for two reasons, this attack was particularly unpleasant. First, not only were Wilson's ideas attacked, but he himself was smeared by being linked with the most reactionary of political thinkers, including the Nazis. (shrink)

The papers presented in this special collection focus upon conceptual, the oretical and epistemological aspects of sociobiology, an emerging discipline that deals with the extent to which genetic factors influence or control patterns of behavior as well as the extent to which patterns of behavior, in turn, influence or control genetic evolution. The Prologue advances a compre hensive acco/unt of the field of gene-culture co-evolution, where Lumsden and Gushurst differentiate between "classical" sociobiology (represented especially by Wilson's early work) (...) and current research on human socio biology (represented by Lumsden and Wilson's later work), which emphasizes interplay between genes, minds, and culture. The specter of genetic deter minism, no doubt, has created considerable controversy, some of which may be laid to rest by Hanna's analysis of the (ambiguous) notion of a "genetic program", which indicates the necessity for distinguishing between descriptive and prescriptive dimensions of this complex concept. Brandon offers a framework for assessing the respective contributions of nature and of nurture by advancing a means for measuring genetic and cultural influences upon "inheritance", which supports the conclusion that evolving patterns of behavior do not always maximize inclusive fitness, contrary to what socio biologists have claimed. The influence of culture upon genetic evolution, of course, can be adequately appraised only when a suitable account of culture itself has been found, a desideratum Smillie attempts to satisfy by utilizing the notion of "cinfo" as culturally transmitted ecological informa tion, a resource other species tend not to exploit.

The 1000-year-old novel The Tale of Genji, written by Murasaki Shikibu around 1002 CE, shows the operation of general principles of sociobiology. Isolated from western influences and cloaked in Japanese traditions, the common traits associated with reproductive processes are clearly evident. The novel depicts the differential investment of males and females in offspring, male competitive behaviors, and concerns for paternity, kin selection, reciprocal social exchange, species-typical emotional expression, female mate choice, positive assortative mating, and acknowledgment of hereditary transmission of (...) physical and psychological traits. The nature of human behavior in Genji’s time seems little different than now and has all the attributes of species-specific and universal traits. Indeed, it can be argued that the fundamental characteristics of Homo sapiens have never changed, being influenced only in form by culture. The qualitative and quantitative evaluation of ancient texts is a strong methodology for understanding the invariant nature of human behavior. (shrink)

In the years leading up to the Second World War the ethologists Konrad Lorenz and Nikolaas Tinbergen, created the tradition of rigorous, Darwinian research on animal behavior that developed into modern behavioral ecology. At first glance, research on specifically human behavior seems to exhibit greater discontinuity that research on animal behavior in general. The 'human ethology' of the 1960s appears to have been replaced in the early 1970s by a new approach called ‘sociobiology’. Sociobiology in its turn appears (...) to have been replaced by an approach calling itself Evolutionary Psychology. Closer examination, however, reveals a great deal of continuity between these schools. At present, whilst Evolutionary Psychology is the most visible form of evolutionary psychology, empirical and theoretical research on the evolution of mind and behavior is marked by a diversity of ideas and approaches and it is far from clear which direction(s) the field will take in future.

Politics is a part of human life, and biology is the study of life. All political beings are biological organisms. These are truisms, but they might suggest lines of investigation. Sociobiology, the name suggests, means social theory taken as a branch of the life sciences. Human sociobiology, then, would apply biological theory to human society. How might this be done?

In the intellectual lineage of sociobiology (understood as evolutionary social science), this article considers the place of moral discourse in the evolution of emergent systems for mediating behavior. Given that humans share molecular systems, reflex systems, drive systems, emotional systems, and cognitive systems with chimpanzees, why is it that human behavior is so radically different from chimpanzee behavior? The answer is that, unlike chimps, humans possess symbolic systems, empowering them to override chimplike default morality in favor of symbolically mediated (...) moral codes. The article concludes with a brief discussion of the power of religious symbols to influence moral behavior by reprogramming emotional systems. (shrink)

Sociobiology is the scientific study of why organisms sometimes associate with other organisms. This paper surveys recent research on the reasons for altruism and aggression. It also considers the contributions an individual's genes and its environment make to its behavior, and it reviews functional theories for the evolution of cannibalism, polygamy, homosexuality, and infanticide in humans and other animals. Finally mention is made of the limited and generally negative attitude of sociobiology to religion.

The debate about the credentials of sociobiology has persisted because scholars have failed to distinguish the varieties of sociobiology and because too little attention has been paid to the details of the arguments that are supposed to support the provocative claims about human social behavior. I seek to remedy both deficiencies. After analysis of the relationships among different kinds of sociobiology and contemporary evolutionary theory, I attempt to show how some of the studies of the behavior of (...) nonhuman animals meet the methodological standards appropriate to evolutionary research. I contend that the efforts of E. O. Wilson, Richard Alexander, Charles Lumsden, and others to generate conclusions about human nature are flawed, both because they apply evolutionary ideas in an unrigorous fashion and because they use dubious assumptions to connect their evolutionary analyses with their conclusions. This contention rests on analyses of many of the major sociobiological proposals about human social behavior, including: differences in sex roles, racial hostility, homosexuality, conflict between parents and adolescent offspring, incest avoidance, the avunculate, alliances in combat, female infanticide, and gene–culture coevolution.Vaulting Ambitionthus seeks to identify what is good in sociobiology, to expose the errors of premature speculations about human nature, and to prepare the way for serious study of the evolution of human social behavior.

This book examines sociobiology’s validity and significance, using the sociobiological theory of the evolution of mating and parenting as an example. It identifies and discusses the array of factors that determine sociobiology’s effort to become a science, providing a rare, balanced account—more critical than that of its advocates and more constructive than that of its critics. It sees a role for sociobiology in changing the way we understand the goals of evolutionary biology, the proper way to evaluate (...) emerging sciences, and the deep structure of scientific theories. The book’s premise is that evolutionary biology would not be complete if it did not explain evolutionarily significant social facts about nonhumans and humans. It proposes that explanations should be evaluated in terms of their basis in underlying theories, research programs, and conceptual frameworks. (shrink)

The broad character of the arguments used by sociobiologists is assessed, particularly in relation to criticisms coming from anthropology. The implications of sociobiology for theology are developed with respect to the general impact of evolutionary ideas, the reductionist assumptions of sociobiologists, whether or not “survival” can be a value, and more holistic accounts of the physical and biological grounding of the mental and spiritual lives of human beings.

Is sociobiology a new paradigm? A number of people have claimed that it is. I argue that, sociologically speaking, it may well be. But epistemologically, it is not. The case rests on one's interpretation of the major Darwinian evolutionary mechanism, natural selection. In this note, it is shown that sociobiology relies on an orthodox understanding of selection. Thus, in crucial epistemological respects, sociobiology is continuous with the rest of Darwinian evolutionary theory.

Sociobiology has always had a strong relationship with classical psychometrics, and with intelligence testing in particular. The major ideological impact of Eugenics prior to 1940 led many psychometricians to adopt a sociobiological perspective, but when this turned out, in the 1960's, to be controversial many of the procedures of classical psychometrics were abandoned. Their place was taken by functional psychometrics, based on criterion reference testing, where the content of test items was related directly to very specific skills which may (...) be required in the work place or other setting, and the use of intervening psychological traits such as intelligence was eliminated. It is demonstrated here that much of the theory of traits can be derived directly from functional psychometrics, without the need to make any sociobiological presuppositions. (shrink)

The term 'sociobiology' was introduced in E. O. Wilson's Sociobiology: The New Synthesis (1975) as the application of evolutionary theory to social behavior. Sociobiologists claim that many social behaviors have been shaped by natural selection for reproductive success, and they attempt to reconstruct the evolutionary histories of particular behaviors or behavioral strategies. This survey attempts to clarify and evaluate the aim of sociobiology. Given that a neutral account is impossible, this entry does the next best thing. It (...) takes sociobiology as well as its critics seriously. On the one hand, by demonstrating that current studies of evolution and human behavior are based on Darwin's arguments for evolution (properly updated), we gain a strong rationale for thinking that something closer to sociobiology than to disconnectionism is needed to properly understand human sociality. Nevertheless, this survey reconstructs sociobiology in its best light, according to its aims. Consequently, criticism of sociobiology as it is actually practiced is not ignored or dismissed. This approach reveals what is best about sociobiology, while remaining sensitive to many of the problems it has generated. (shrink)

A great deal has been written during the past decade about the subject of sociobiology. The appearance of E. O. Wilson’s massive text, Sociobiology: The New Synthesis, set off interdisciplinary tremors whose vibrations are still being felt in such exotic parts of the academic world as philosophy. Yet despite all the attention directed toward sociobiology within and beyond the university by both its admirers and detractors, some very basic issues pertaining to the subject remain notably obscure.

The topic of sociobiology and ethics opens up a range of questions that have to do with important relationships: between the history of nature and human being, between biological evolution and psychosocial evolution, between is and ought, between language usages in one domain and another. The task of ethics is properly to discern what sociobiology has to tell us about the fundamentals of life and persuasively to direct our actions in accord with those fundamentals, in a manner that (...) is consistent with our essential humanity. From the theological perspective all of this transpires within the creative will of God. (shrink)

Much theorizing about altruism has been undertaken within a naturalistic and deterministic sociobiological framework that has sought to explain altruistic action in terms of underlying genetic selfishness. Recently, however, social constructionist thinkers have developed an alternative to such theorizing which suggests that human action arises out of fundamentally open-ended and malleable social relationships. This paper intends to show, however, that a reductive egoism is nonetheless still at work in such accounts, typically taking the form of an underlying concern for matters (...) of personal status and social recognition. As a response, this paper will briefly outline the work of the French phenomenologists Maurice Merleau-Ponty and Emmanuel Levinas as an example of non-reductive and fundamentally Other-oriented alternatives to both sociobiological and social constructionist accounts of altruistic action.

This essay views Christian doctrines of the atonement in the light of evolution and sociobiology. It argues that most of the doctrines are false because they use a false premise, the historicity of Adam and the Fall. However, two doctrines are not false on those grounds: Abelard’s idea that Jesus’ life is an example and Athanasius’s concept that the atonement changes human nature. Employing evolution’s and sociobiology’s concepts of the egocentric and ethnocentric nature of humanity and the synergy (...) between genes and environments to produce a "nature," this essay shows that these two doctrines can be amalgamated to make sense of the atonement in the late twentieth century. (shrink)

This paper argues that the creation narrative of the Fall in Genesis 2:4b–3:24 is not history and does not contain a doctrine of original sin. The doctrine of original sin as a theory of human nature needs a new foundation. The contemporary science of sociobiology has a theory of human nature that is remarkably similar to major versions of the Christian doctrines of original sin. To incorporate sociobiology's theory of human nature into Christianity is to lay the foundation (...) for a new, ecumenical understanding of original sin. (shrink)

Indirect speech is a remarkable trait of human communication. The present paper tackles the sociobiological underpinnings of communicative indirectness discussing both socio-interactional and cognitive rationales behind its manifestation in discourse. From a social perspective, the use of indirect forms in interactions can be regarded as an adaptive response to the epistemic implications of transacted new information in small primary groups, representing – in Givón’s terms – our “bio-cultural” descent. The design features of indirect strategies today may therefore be explained in (...) terms of a form-function mapping in which indirect communicative expressions allowed a “safer” transaction of contents and a more cooperative attitude of speakers in both face-to-face and public contexts of communication. The unchallengeability effects notably induced by underencoded meanings have now received extensive experimental backing, unveiling intriguing underlying cognitive mechanisms such as the well-known cognitive illusions or fallacies.

This paper addresses a nonspecialist audience on how sociobiological accounts of human nature might be relevant to Christian theology. I begin with some confessional remarks to clarify what I mean by Christian theology and how I understand it to be related to science. I indicate briefly why sociobiology might be of interest to theology and then move on to sketch some ways in which sociobiology might relate to theological ethics. My basic point is that sociobiology is directly (...) relevant to theological ethics in its understanding of evolved human emotional predispositions but not in its normative reflection proper. (shrink)

ABSTRACT Despite its excesses, sociobiology can make a useful contribution to ethics, if it is recognised that it need not impinge on free‐will, and if the ‘naturalistic fallacy’ can be avoided. This contribution is the central concept of evolutionary stability, and the implication which can be drawn from it, that concern for the future is a basic part of human nature. In stable societies, such concern is manifested as fear of change, or strict adherence to tradition, but modern ideas (...) of progress have engendered a cavalier attitude to the more distant future, and current ethical systems cannot get to grips with duties towards future generations. It is suggested that the popularity of sociobiology and the present‐day interest in conservation both reflect an aspect of human nature which has too long been neglected by moralists. (shrink)

E. O. Wilson argues that we must use scientifically based reason to solve the values dilemma created by the loss of a transcendent foundation for values. Peter Singer allows that sociobiology can help us understand the evolutionary origin of ethics, but denies the claim that sociobiology or any science can furnish us with ultimate ethical principles. We argue that Singer's critique of Wilson's attempt to bridge the gap between fact and value using empirical reason is unconvincing and that (...) Singer's own ethical principle of disinterestedness requires major support from empirical reason and is not sustainable by pure reason alone. (shrink)

When the sociobiology debate erupted in 1975, there were almost too many contributions to the heated exchanges between sociobiologists and their critics to count. In the fall of 1976, a Canadian educational film entitled _Sociobiology: Doing What Comes Naturally_ sparked further controversy due to its graphic visuals and outrageous narration. While critics claimed the film was a promotional tool to further the sociobiological agenda in educational settings, sociobiologists quickly distanced themselves from the film and, in turn, accused the critics (...) of consciously misrepresenting sociobiology by organizing showings of the film. Using audio, video, archival, and published sources, this paper explores the complicated history of _Sociobiology: Doing What Comes Naturally_ and demonstrates how the public debate about the film reflects the positions, polemics, and polarization of the sociobiology debate as a whole.

This article presents the rationale of a new approach to the debate between sociobiology and religion. In it, I outline a sociobiology that may generate alternative and competing hypotheses about the existence of gods as beings (theisms) and the nature of their participation in the universe. I examine the central theoretical issues of this sociobiology and discuss the strengths and weaknesses of a sociobiological approach to theological issues, including problems pertinent to nontheistic theologies. A concluding case is (...) made for an enriched and revitalized agenda in the dialogue between sociobiology and religion. While consistent with current research on gene‐culture coevolution, the article's treatment expands on earlier work to begin incorporating theoretical terms that carry a more direct theological impact.

This paper aims at bridging a gap between the history of American animal behavior studies and the history of sociobiology. In the post-war period, ecology, comparative psychology and ethology were all investigating animal societies, using different approaches ranging from fieldwork to laboratory studies. We argue that this disunity in “practices of place” explains the attempts of dialogue between those three fields and early calls for unity through “sociobiology” by J. Paul Scott. In turn, tensions between the naturalist tradition (...) and the rising reductionist approach in biology provide an original background for a history of Edward Wilson’s own version of sociobiology, much beyond the William Hamilton’s papers usually considered as its key antecedent. Naturalists were in a defensive position in the geography of the fields studying animal behavior, and in reaction were a driving force behind the various projects of synthesis called “sociobiology”.

The fundamental tenet of contemporary sociobiology, namely the assumption of a single process of evolution involving the selection of genes, is critically examined. An alternative multiple-level, multiple-process model of evolution is presented which posits that the primary process that operates via selection upon the genes cannot account for certain kinds of biological phenomena, especially complex, learned, social behaviours. The primary process has evolved subsidiary evolutionary levels and processes that act to bridge the gap between genes and these complex behaviours. (...) The subsidiary levels are development, individual animal learning, and socioculture itself. It is argued that individual learning is pivotal to the derivation and biological analysis of culture. The differences between cultural and noncultural societies are stressed. It is concluded that such a multiple-level model of evolution can form the basis for reconciling opposing sides in the sociobiology debate. (shrink)

The semantic view of scientific theories has been defended as more adequate than the “received” view, especially with respect to biological theories (Beatty 1980, 1981; Thompson 1983). However, the semantic view has not been evaluated on its own terms. In this paper I first show how the theory of sociobiology propounded by E.O. Wilson (1975) can be understood on the semantic approach. I then discuss the criticism that Wilson’s theory is beset by the problem of unreliable generalizations. I suggest (...) that this problem results from the use of the model-building strategy in theory. I conclude that the problem is pressing enough to impugn the semantic view as an adequate account of sociobiological theory.According to proponents of the semantic view of theories, scientific theories function to specify a class of “models,” interpretations, or representations of their postulates.

The essay explores the development of sociobiology, its basic tenets, and its contributions to the study of human nature as well as ethics. It insists that Darwinism is more than a biological theory and presents a possibility of interpreting sociobiology as manifesting not the triumph of the selfish gene but, on the contrary, the only way in which the expansion of altruism was possible.

The term ‘sociobiology’ was introduced in E. O. Wilson's Sociobiology: The New Synthesis (1975) as the application of evolutionary theory to social behavior. Sociobiologists claim that many social behaviors have been shaped by natural selection for reproductive success, and they attempt to reconstruct the evolutionary histories of particular behaviors or behavioral strategies.

Zygon has been discussing the implications of sociobiology for twenty‐five years, ever since E. O. Wilson's book by that name first burst upon the stage. In the course of that discussion there have been many heated exchanges, but in this journal, at least, the heat has also generated light. Thus it is now timely and useful to review and consolidate Zygon's approach to the sociobiology construct, not only as it was originally presented but as it has changed over (...) time. The goal of this article is to recapitulate and summarize the dialogue that has taken place here. But my aim is not merely to rehash the discussion; it is more precisely to extend and continue it. Specific proposals are offered that are designed to ground future conversations on the solid foundation that has been established over the last quarter century. (shrink)

Sociopaths are “outstanding” members of society in two senses: politically, they draw our attention because of the inordinate amount of crime they commit, and psychologically, they hold our fascination because most ofus cannot fathom the cold, detached way they repeatedly harm and manipulate others. Proximate explanations from behavior genetics, child development, personality theory, learning theory, and social psychology describe a complex interaction of genetic and physiological risk factors with demographic and micro environmental variables that predispose a portion of the population (...) to chronic antisocial behavior. More recent, evolutionary and game theoretic models have tried to present an ultimate explanation of sociopathy as the expression of a frequency-dependent life strategy which is selected, in dynamic equilibrium, in response to certain varying environmental circumstances. This paper tries to integrate the proximate, developmental models with the ultimate, evolutionary ones, suggesting that two developmentally different etiologies of sociopathy emerge from two different evolutionary mechanisms. Social strategies for minimizing the incidence of sociopathic behavior in modern society should consider the two different etiologies and the factors that contribute to them. (shrink)

Although classical evolutionary theory, i.e., population genetics and the Modern Synthesis, was already implicitly ‘gene-centred’, the organism was, in practice, still generally regarded as the individual unit of which a population is composed. The gene-centred approach to evolution only reached a logical conclusion with the advent of the gene-selectionist or gene’s eye view in the 1960s and 1970s. Whereas classical evolutionary theory can only work with fitness differences between individual organisms, gene-selectionism is capable of working with fitness differences among genes (...) within the same organism and genome. Here, we explore the explanatory potential of ‘intra-organismic’ and ‘intra-genomic’ gene-selectionism, i.e., of a behavioural-ecological ‘gene’s eye view’ on genetic, genomic and organismal evolution. First, we give a general outline of the framework and how it complements the—to some extent—still ‘organism-centred’ approach of classical evolutionary theory. Secondly, we give a more in-depth assessment of its explanatory potential for biological evolution, i.e., for Darwin’s ‘common descent with modification’ or, more specifically, for ‘historical continuity or homology with modular evolutionary change’ as it has been studied by evolutionary developmental biology during the last few decades. In contrast with classical evolutionary theory, evo-devo focuses on ‘within-organism’ developmental processes. Given the capacity of gene-selectionism to adopt an intra-organismal gene’s eye view, we outline the relevance of the latter model for evo-devo. Overall, we aim for the conceptual integration between the gene’s eye view on the one hand, and more organism-centred evolutionary models on the other. (shrink)

This article examines the belief among the cultural elites that ‘people’ should be protected from dangerous knowledge, ‘dangerous’ in the sense that there are factual statements which may have negative moral and political consequences to society. Such a belief in the negative consequences of dangerous – that is, politically suspicious – knowledge represents an intellectual tradition that goes back to Plato and his famous state‐utopian work Republic. This article analyses moral interpretations of statements regarding matters of fact (so‐called moral reading), (...) and draws conclusions about the reasons why knowledge can be considered dangerous to ‘the people’ or to some specific groups in the population, such as children, mothers, students, the sick and dying and the working class. The so‐called sociobiology debate, a controversy that started with the publication of the zoologist E.O. Wilson’s Sociobiology in 1975, is discussed in this article as a ‘case study’ of dangerous knowledge. (shrink)

Sociobiologists explain human social behavior as genetically adapative. The intervention of cultural learning into the processes of the acquisition and transmission of human behavior makes such explanation prima facie unjustified. William Durham has developed a theory of coevolution which claims that although the processes of genetic evolution and cultural evolution are independent, the results of the two processes are "functionally complementary." In this paper I characterize the conditions necessary for giving an explanation by adaptation of human behavior and argue that (...) Durham's defense of functional complementarity cannot be justified until further evidence of the causal background conditions of cultural transmission and selection are presented. (shrink)

Book reviewed in this article: The Expanding Circle: Ethics and Sociobiology. By Peter Singer.

Among the numerous criticisms of sociobiology is the criticism that it is not genuine science. This paper defends sociobiology against this criticism. There are three aspects to the defense. First, it is argued that the testability criterion of pseudoscience is generally problematic as a criterion and that even if accepted it fails to mark sociobiology as a pseudoscience. Second, it is argued that Thagard's more comprehensive and sophisticated criterion of pseudoscience fails to mark sociobiology as a (...) pseudoscience. Third, a positive case for accepting sociobiology as genuine science is presented. (shrink)

Recent deconstructive developments in ecology (doubts about the existence of unified communities and ecosystems, the diversity-stability hypothesis, and a natural homeostasis or “balance of nature”; and an emphasis on “chaos,” “perturbation,” and directionless change in living nature) and the advent of sociobiology (selfish genes) may seem to undermine the scientific foundations of environmental ethics, especially the Leopold land ethic. A reassessment of the Leopold land ethic in light of these developments (and vice versa) indicates that the land ethic is (...) still a viable environmental ethic, if judiciously updated and revised.
