This collection of essays explores the metaphysical thesis that the living world is not made up of substantial particles or things, as has often been assumed, but is rather constituted by processes. The biological domain is organised as an interdependent hierarchy of processes, which are stabilised and actively maintained at different timescales. Even entities that intuitively appear to be paradigms of things, such as organisms, are actually better understood as processes. Unlike previous attempts to articulate processual views of biology, which (...) have tended to use Alfred North Whitehead’s panpsychist metaphysics as a foundation, this book takes a naturalistic approach to metaphysics. It submits that the main motivations for replacing an ontology of substances with one of processes are to be found in the empirical findings of science. Biology provides compelling reasons for thinking that the living realm is fundamentally dynamic, and that the existence of things is always conditional on the existence of processes. The phenomenon of life cries out for theories that prioritise processes over things, and it suggests that the central explanandum of biology is not change but rather stability, or more precisely, stability attained through constant change. This edited volume brings together philosophers of science and metaphysicians interested in exploring the consequences of a processual philosophy of biology. The contributors draw on an extremely wide range of biological case studies, and employ a process perspective to cast new light on a number of traditional philosophical problems, such as identity, persistence, and individuality.

This chapter argues that scientific and philosophical progress in our understanding of the living world requires that we abandon a metaphysics of things in favour of one centred on processes. We identify three main empirical motivations for adopting a process ontology in biology: metabolic turnover, life cycles, and ecological interdependence. We show how taking a processual stance in the philosophy of biology enables us to ground existing critiques of essentialism, reductionism, and mechanicism, all of which have traditionally been associated with (...) substance ontology. We illustrate the consequences of embracing an ontology of processes in biology by considering some of its implications for physiology, genetics, evolution, and medicine. And we attempt to locate the subsequent chapters of the book in relation to the position we defend. (shrink)

Philosophers of biology, along with everyone else, generally perceive life to fall into two broad categories, the microbes and macrobes, and then pay most of their attention to the latter. ‘Macrobe’ is the word we propose for larger life forms, and we use it as part of an argument for microbial equality. We suggest that taking more notice of microbes – the dominant life form on the planet, both now and throughout evolutionary history – will transform some of the philosophy (...) of biology’s standard ideas on ontology, evolution, taxonomy and biodiversity. We set out a number of recent developments in microbiology – including biofilm formation, chemotaxis, quorum sensing and gene transfer – that highlight microbial capacities for cooperation and communication and break down conventional thinking that microbes are solely or primarily single-celled organisms. These insights also bring new perspectives to the levels of selection debate, as well as to discussions of the evolution and nature of multicellularity, and to neo-Darwinian understandings of evolutionary mechanisms. We show how these revisions lead to further complications for microbial classification and the philosophies of systematics and biodiversity. Incorporating microbial insights into the philosophy of biology will challenge many of its assumptions, but also give greater scope and depth to its investigations. (shrink)

[John Dupré] This paper attacks some prominent contemporary attempts to provide reductive accounts of ever wider areas of human behaviour. In particular, I shall address the claims of sociobiology (or evolutionary psychology) to provide a universal account of human nature, and attempts to subsume ever wider domains of behaviour within the scope of economics. I shall also consider some recent suggestions as to how these approaches might be integrated. Having rejected the imperialistic ambitions of these approaches, I shall briefly (...) advocate a more pluralistic approach to the understanding of human behaviour, and one which leaves some space for the possibility of genuine human autonomy. /// [John O'Neill] One response to Dupré's criticism of rational choice theory's unifying aspirations is that it is aimed at over-ambitious versions of the theory. Immodesty about the scope of rational choice theory may look more plausible given suitable modesty in assumptions about the rational agent. The paper examines problems with one immodest version of the theory-public choice theory-and show how these shed light on problems in modest versions employing minimal assumptions about the preference structure of rational agents. However, while rational choice theory may fail in its unifying ambitions, I argue those aspirations are defensible. (shrink)

John Dupré explores recent revolutionary developments in biology and considers their relevance for our understanding of human nature and human society. Epigenetics and related areas of molecular biology have eroded the exceptional status of the gene and presented the genome as fully interactive with the rest of the cell. Developmental systems theory provides a space for a vision of evolution that takes full account of the fundamental importance of developmental processes. Dupré shows the importance of microbiology for a proper (...) understanding of the living world, and reveals how it subverts such basic biological assumptions as the organisation of biological kinds on a branching tree of life, and the simple traditional conception of the biological organism.

John Dupre warns that our understanding of human nature is being distorted by two faulty and harmful forms of pseudo-scientific thinking. Not just in the academic world but in everyday life, we find one set of experts who seek to explain the ends at which humans aim in terms of evolutionary theory, while the other set uses economic models to give rules of how we act to achieve those ends. Dupre demonstrates that these theorists' explanations do not (...) work and that, if taken seriously, their theories tend to have dangerous social and political consequences. For these reasons, it is important to resist scientism: an exaggerated conception of what science can be expected to do for us. Dupre restores sanity to the study of human nature by pointing the way to a proper understanding of humans in the societies that are our natural and necessary environments. Anyone interested in science and human life will enjoy this book--unless they are its targets. (shrink)

This paper presents a brief response to Robert A. Wilson's critical discussion of Promiscuous Realism [1996]. I argue that, although convergence on a unique conception of species cannot be ruled out, the evidence against such an outcome is stronger than Wilson allows. In addition, given the failure of biological science to come up with a unique and privileged set of biological kinds, the relevance of the various overlapping kinds of ordinary language to the metaphysics of biological kinds is greater than (...) Wilson admits. (shrink)

This book is a collection of essays by a leading philosopher of biology and spans his career over almost the last twenty years. Most of the topics that have been of concern to philosophers of biology in this period are touched on to some extent, and the collection of these essays in a convenient volume will certainly be welcomed by everyone working in this field. The essays are arranged chronologically, and divided into three sections. Although the chapters in the first (...) section have substantial interconnections, being involved with fundamental conceptual issues in evolutionary theory, on the whole there is not much attempt to tie the book into anything more than a sequence of independent essays. The later sections, moreover, cover a quite diverse range of topics. The whole is neither more nor less than the sum of the parts. For. (shrink)

We address three fundamental questions: What does it mean for an entity to be living? What is the role of inter-organismic collaboration in evolution? What is a biological individual? Our central argument is that life arises when lineage-forming entities collaborate in metabolism. By conceiving of metabolism as a collaborative process performed by functional wholes, which are associations of a variety of lineage-forming entities, we avoid the standard tension between reproduction and metabolism in discussions of life – a tension particularly evident (...) in discussions of whether viruses are alive. Our perspective assumes no sharp distinction between life and non-life, and does not equate life exclusively with cellular or organismal status. We reach this conclusion through an analysis of the capabilities of a spectrum of biological entities, in which we include the pivotal case of viruses as well as prions, plasmids, organelles, intracellular and extracellular symbionts, unicellular and multicellular life-forms. The usual criterion for classifying many of the entities of our continuum as non-living is autonomy. This emphasis on autonomy is problematic, however, because even paradigmatic biological individuals, such as large animals, are dependent on symbiotic associations with many other organisms. These composite individuals constitute the metabolic wholes on which selection acts. Finally, our account treats cooperation and competition not as polar opposites but as points on a continuum of collaboration. We suggest that competitive relations are a transitional state, with multi-lineage metabolic wholes eventually outcompeting selfish competitors, and that this process sometimes leads to the emergence of new types or levels of wholes. Our view of life as a continuum of variably structured collaborative systems leaves open the possibility that a variety of forms of organized matter – from chemical systems to ecosystems – might be usefully understood as living entities.

This article argues, in opposition to a common interpretation of Wittgenstein deriving from Winch, that there is nothing especially problematic about the social sciences. Familiar Wittgensteinian theses about language, notably on the open-endedness of linguistic rules and on the importance of family resemblance concepts, have great relevance not only to the social sciences but also to much of the natural sciences. The differences between scientific and ordinary language are much less sharp than Winch, and probably Wittgenstein, supposed.

A recent paper by John Watkins argues that the Baldwin effect, a hypothetical evolutionary process by which a culturally evolved behavior might promote the evolution of a genetic basis for that behavior, is inconsistent with evolutionary theory. In this reply, I argue that in case the genetic basis of the behavior in question determines separable constituents of the behavior, Watkins's argument is unsound.

John Dupr presents a set of provocative and highly readable essays exploring the ways in which we categorize animals, including humans: he comes to surprisingly radical conclusions. We must reject the idea that each organism has an essence that determines its necessary place in the unique hierarchy of things. Nature is not organized in a single system. It is a mistake to generalize about human nature--for instance, about the gender roles or sexual behaviour of our species. We must take (...) a pluralistic view of biology and the human sciences.

This paper considers the applicability of standard accounts of causation to living systems. In particular it examines critically the increasing tendency to equate causal explanation with the identification of a mechanism. A range of differences between living systems and paradigm mechanisms are identified and discussed. While in principle it might be possible to accommodate an account of mechanism to these features, the attempt to do so risks reducing the idea of a mechanism to vacuity. It is proposed that the solution (...) to this problem requires the development of a philosophical account of process adequate to apply to living systems. (shrink)

Metagenomics is an emerging microbial systems science that is based on the large-scale analysis of the DNA of microbial communities in their natural environments. Studies of metagenomes are revealing the vast scope of biodiversity in a wide range of environments, as well as new functional capacities of individual cells and communities, and the complex evolutionary relationships between them. Our examination of this science focuses on the ontological implications of these studies of metagenomes and metaorganisms, and what they mean for common (...) sense and philosophical understandings of multicellularity, individuality and organism. We show how metagenomics requires us to think in different ways about what human beings are and what their relation to the microbial world is. Metagenomics could also transform the way in which evolutionary processes are understood, with the most basic relationship between cells from both similar and different organisms being far more cooperative and less antagonistic than is widely assumed. In addition to raising fundamental questions about biological ontology, metagenomics generates possibilities for powerful technologies addressed to issues of climate, health and conservation. We conclude with reflections about process-oriented versus entity-oriented analysis in light of current trends towards systems approaches. (shrink)

It has increasingly been recognised that units of biological classification cannot be identified with the units of evolution. After briefly defending the necessity of this distinction I argue, contrary to the prevailing orthodoxy, that species should be treated as the fundamental units of classification and not, therefore, as units of evolution. This perspective fits well with the increasing tendency to reject the search for a monistic basis of classification and embrace a pluralistic and pragmatic account of the species category. It (...) also provides a diagnosis of the paradoxical but popular idea that species are individuals: Species are not individuals, but the units of evolution are. (shrink)

The traditional home for the concept of a natural kind in biology is of course taxonomy, the sorting of organisms into a nested hierarchy of kinds. Many taxonomists and most philosophers of biology now deny that it is possible to sort organisms into natural kinds. Many do not think that biological taxonomy sorts them into kinds at all, but rather identifies them as parts of historical individuals. But at any rate if the species, genera and so on of biological taxonomy (...) are kinds at all, there are various respects in which they fall short of the traditional requirements of naturalness. The members of biological taxa lack essential properties that make them members of a particular kind: any properties specific enough to belong only to members of the kind cannot be assumed to belong to all members of the kind. And if there are laws applying to members of biological taxa they are laws of very minor and local importance and, in view of the preceding point, at best probabilistic. (shrink)

This chapter defends a pluralistic view of science: the various projects of enquiry that fall under the general rubric of science share neither a methodology nor a subject matter. Ontologically, it is argued that sciences need have nothing in common beyond an antipathy to the supernatural. Epistemically one central virtue is defended, empiricism, meaning just that scientific knowledge must ultimately be answerable to experience. Prima facie science is as diverse as the world it studies; and rejection of this prima facie (...) diversity in favour of a spurious aspiration to unity is grounded in a priori assumption not experience. Disunity, however, does not mean disconnectedness, and the connections between different areas of knowledge are an important theme in the book. (shrink)

Humans are a kind of animal, and it is a natural and sensible idea that the way to understand what it is for a human person to persist over time is to reflect on what it is for an animal to persist. This paper accepts this strategy. However, especially in the light of a range of recent biological findings, the persistence of animals turns out to be much more problematic than is generally supposed. The main philosophical premise of the paper (...) is that living systems generally are best treated as processes rather than things. These processes prove to be so complexly intertwined and interdependent, that there is no unique, objective way of distinguishing the individuals from which they are composed. For this reason the animalist perspective, it is argued, problematizes as much as it resolves the problem of personal identity. Traditional concerns with responsibility and reactive attitudes provide an intelligible and defensible motivation for distinguishing the individuals we standardly assume as the explanandum in these discussions. But, from a biological point of view, the underlying individualism is a contingent perspective, as much justified by these concerns as providing an objective grounding for them. (shrink)

In an earlier paper (Dupré 1984), I criticized a thesis sometimes defended by theorists of probabilistic causality, namely, that a probabilistic cause must raise the probability of its effect in every possible set of causally relevant background conditions (the "contextual unanimity thesis"). I also suggested that a more promising analysis of probabilistic causality might be sought in terms of statistical relevance in a fair sample. Ellery Eells (1987) has defended the contextual unanimity thesis against my objections, and also raised objections (...) of his own to my positive claims. In this paper I defend and amplify both my objections to the contextual unanimity thesis and my constructive suggestion. (shrink)

Recent molecular biology has seen the development of genomics as a successor to traditional genetics. This paper offers an overview of the structure, epistemology, and history of contemporary genomics. A particular focus is on the question to what extent the genome contains, or is composed of, anything that corresponds to traditional conceptions of genes. It is concluded that the only interpretation of genes that has much contemporary scientific relevance is what is described as the "developmental defect" gene concept. However, developmental (...) defect genes typically only correspond to general areas of the genome and not to precise chemical structures . The parts of the genome to be identified for an account of the processes of normal development are highly diverse, little correlated with traditional genes, and act in ways that are highly dependent on the cellular and higher level environment. Despite its historical development out of genetics, genomics represents a radically different kind of scientific project. (shrink)

It has notoriously been supposed that the doctrine of determinism conflicts with the belief in human freedom. Yet it is not readily apparent how indeterminism, the denial of determinism, makes human freedom any less problematic. It has sometimes been suggested that the arrival of quantum mechanics should immediately have solved the problem of free will and determinism. It was proposed, perhaps more often by scientists than by philosophers, that the brain would need only to be fitted with a device for (...) amplifying indeterministic quantum phenomena for the bogey of determinism to be defeated. Acts of free will could then be those that were initiated by such indeterministic nudges. Recently there has been some inclination to revive such a story as part of the fallout from the trend for chaos theory. Chaotic systems in the brain, being indefinitely sensitive to the precise details of initial conditions, seem to provide fine candidates for the hypothetical amplifiers of quantum events. (shrink)

This paper attacks the perennial philosophical and scientific quest for a simple and unified vision of the world. Without denying the attraction of this vision, I argue that such a goal often seriously distorts our understanding of complex phenomena. The argument is illustrated with reference to simplistic attempts to provide extremely general views of biology, and especially of human nature, through the theory of evolution. Although that theory is a fundamental ingredient of our scientific world view, it provides only one (...) of a number of perspectives that are required for an understanding of biology in general, and human behaviour in paticular. The argument is connected to the replacement of views of science in terms of universal laws with views that emphasise ranges of models more locally suited to specific phenomena. (shrink)

Standard microbial evolutionary ontology is organized according to a nested hierarchy of entities at various levels of biological organization. It typically detects and defines these entities in relation to the most stable aspects of evolutionary processes, by identifying lineages evolving by a process of vertical inheritance from an ancestral entity. However, recent advances in microbiology indicate that such an ontology has important limitations. The various dynamics detected within microbiological systems reveal that a focus on the most stable entities (or features (...) of entities) over time inevitably underestimates the extent and nature of microbial diversity. These dynamics are not the outcome of the process of vertical descent alone. Other processes, often involving causal interactions between entities from distinct levels of biological organisation, or operating at different time scales, are responsible not only for the destabilisation of pre-existing entities, but also for the emergence and stabilisation of novel entities in the microbial world. In this article we consider microbial entities as more or less stabilised functional wholes, and sketch a network-based ontology that can represent a diverse set of processes including, for example, as well as phylogenetic relations, interactions that stabilise or destabilise the interacting entities, spatial relations, ecological connections, and genetic exchanges. We use this pluralistic framework for evaluating (i) the existing ontological assumptions in evolution (e.g. whether currently recognized entities are adequate for understanding the causes of change and stabilisation in the microbial world), and (ii) for identifying hidden ontological kinds, essentially invisible from within a more limited perspective. We propose to recognize additional classes of entities that provide new insights into the structure of the microbial world, namely “processually equivalent” entities, “processually versatile” entities, and “stabilized” entities.

Much scientific thinking and thinking about science involves assumptions that there is a deep and pervasive order to the world that it is the business of science to disclose. A paradigmatic statement of such a view can be found in a widely discussed paper by a prominent economist, Milton Friedman (a paper which will be discussed in more detail shortly): A fundamental hypothesis of science is that appearances are deceptive and that there is a way of looking at or interpreting (...) or organizing the evidence that will reveal superficially disconnected and diverse phenomena to be manifestations of a more fundamental and relatively simple structure. (1953/1984, p.231) On the other hand, the person sometimes described as the father of modern science, Francis Bacon, wrote: The human understanding is of its own nature prone to suppose the existence of more order and regularity in the world than it finds. And though there be many things in nature which are singular and unmatched, yet it devises for them conjugates and relatives which do not exist. (1620/1960, p. 50). (shrink)

Charles Darwin transformed our understanding of the universe and our place in it with his development of the theory of evolution. 150 years later, we are still puzzling over the implications.

He shows why the theory of evolution is one of the most important scientific ideas of all time, but makes clear that it can't explain everything - contrary to widespread popular belief, it has very little to tell us about the details of human nature and human behaviour, such as language, culture, and sexuality.Darwin's Legacy clears a path through the confusion and controversy surrounding evolution; anyone who is interested in understanding what the theory of evolution can and can't do will find this a compelling and enjoyable introduction.

This paper will begin with some very broad and general considerations about the kind of biological entities we are. This exercise is motivated by the belief that the view of what we—multicellular eukaryotic organisms—are that is widely assumed by biologists, medical scientists and the general public, is an extremely limited one. It cannot be assumed a priori that a more sophisticated view will make a major difference to the science or practice of medicine, and there are areas of medicine to (...) which it is probably largely irrelevant. However, in this case there are important implications for medicine, or so I shall argue. In particular, it enables us to appreciate fully the potential medical significance of some of the most exciting contemporary advances in general biology, in such fields as epigenetics, metagenomics, and systems biology; and part of this significance is that these advances have raised serious doubts about how we should understand the biological individuals that medicine is generally assumed to aim to treat.

Contrary to one possible interpretation of my title, this paper will not advocate any scepticism or ontological deflation. My concern will rather be with how we should best think about a realm of phenomena the existence of which is in no doubt, what has traditionally been referred to as the genetic. I have no intention of questioning a very well established scientific consensus on this domain. It involves the chemical DNA, which resides in almost all our cells, which is capable (...) of producing copies of itself that accurately reproduce a very long sequence of components, and which plays a role in the physiology of the cell which in certain basic respects is quite well understood. This substance has also achieved a remarkable iconic status in contemporary culture. It is seen as fundamental to personal identity both in the practical sense of providing a criterion of identity through DNA testing, and in the much deeper sense of being seen as, somehow, defining who we are. The latter role is illustrated, for example, by the recent debate about the right of children conceived by sperm donation to know who are their fathers. Such people, it is passionately argued, must be able to find out where they came from, who they really are. On a daily basis we are confronted with claims about the discovery of the genetic basis of—or in fact very often the ‘gene for’—all manner of psychological and physical characteristics, and all kinds of disorders. This holds out apparent possibilities. (shrink)

John Dupré (1984) has recently criticized the theory of probabilistic causality developed by, among others, Good (1961-62), Suppes (1970), Cartwright (1979), and Skyrms (1980). He argues that there is a tension or incompatibility between one of its central requirements for the presence of a causal connection, on the one hand, and a feature of the theory pointed out by Elliott Sober and me (1983), on the other. He also argues that the requirement just alluded to should be given up. (...)

The ‘Tree of Life’ is intended to represent the pattern of evolutionary processes that result in bifurcating species lineages. Often justified in reference to Darwin’s discussions of trees, the Tree of Life has run up against numerous challenges especially in regard to prokaryote evolution. This special issue examines scientific, historical and philosophical aspects of debates about the Tree of Life, with the aim of turning these criticisms towards a reconstruction of prokaryote phylogeny and even some aspects of the standard evolutionary (...) understanding of eukaryotes. These discussions have arisen out of a multidisciplinary collaboration of people with an interest in the Tree of Life, and we suggest that this sort of focused engagement enables a practical understanding of the relationships between biology, philosophy and history.

Systems biology is the rapidly growing and heavily funded successor science to genomics. Its mission is to integrate extensive bodies of molecular data into a detailed mathematical understanding of all life processes, with an ultimate view to their prediction and control. Despite its high profile and widespread practice, there has so far been almost no bioethical attention paid to systems biology and its potential social consequences. We outline some of systems biology's most important socioethical issues by contrasting the concept of (...) systems as dynamic processes against the common static interpretation of genomes. New issues arise around systems biology's capacities for in silico testing, changing cultural understandings of life, synthetic biology, and commercialization. We advocate an interdisciplinary and interactive approach that integrates social and philosophical analysis and engages closely with the science. Overall, we argue that systems biology socioethics could stimulate new ways of thinking about socioethical studies of life sciences. (shrink)

Although molecular biology has meant different things at different times, the term is often associated with a tendency to view cellular causation as conforming to simple linear schemas in which macro-scale effects are specified by micro-scale structures. The early achievements of molecular biologists were important for the formation of such an outlook, one to which the discovery of recombinant DNA techniques, and a number of other findings, gave new life even after the complexity of genotype–phenotype
relations had become apparent. Against this (...) background we outline how a range of scientific developments and conceptual considerations can be regarded as enabling and perhaps necessitating contemporary systems approaches. We suggest that philosophical ideas have a valuable part to play in making sense of complex scientific and disciplinary issues. (shrink)

Philip Kitcher's book begins with a familiar historical overview. In the 1940s and 50s a confident, optimistic vision of science was widely shared by philosophers and historians of science. The goal of science was to discover the truth about nature, and over the centuries science had advanced steadily towards that goal; science discerned the real kinds of things of which the world was composed and the causal relations between them; the methods of science were rational and its deliverances objective; and (...) so on. Only where science failed in some of these respects was there any need to provide external, that is social, political, or individual, explanations of scientific belief. In the late 50s, and especially subsequent to Kuhn's classic, The Structure of Scientific Revolutions, all this started to change. Historians increasingly insisted that the development of science must be treated just like any other cultural process, which meant embedding the narrative of the growth of scientific knowledge fully in the social and political context in which it occurred. This suggested that the view of science as deriving from a uniquely rational process could no longer be sustained. And, notoriously, Kuhn argued that science could not be seen as cumulative across the most dramatic changes in scientific theory. Though philosophers have never given up entirely on the old optimistic picture ("Legend" as Kitcher refers to it), its influence has steadily waned. For various reasons philosophers have become increasingly concerned over whether one could believe scientific claims to be literally true. And influenced by Duhem's thesis, revived by Quine, that scientific theory must always be underdetermined by empirical evidence, they became more sympathetic to the possibility that scientific belief must be explained, at least in substantial part, by much more than the rational objective processes envisioned by Legend. These philosophical doubts existed in uneasy tension with more extreme tendencies toward thoroughgoing relativism or skepticism, and with the movement in the sociology of science to see the whole concern with truth and falsity as an irrelevant diversion.

In his 'The Disorder of Things' John Dupré presents an objection to reductionism which I call the 'anti-essentialist objection': it is that reductionism requires essentialism, and essentialism is false. I unpack the objection and assess its cogency. Once the objection is clearly in view, it is likely to appeal to those who think conceptual analysis a bankrupt project. I offer on behalf of the reductionist two strategies for responding, one which seeks to rehabilitate conceptual analysis and one (more concessive) (...) which avoids commitment to any such analysis.

The topic of this paper is social constructivist doctrines about the nature of scientific knowledge. I don't propose to review all the many accounts that have either claimed this designation or had it ascribed to them. Rather I shall try to consider in a very general way what sense should be made of the underlying idea, and then illustrate some of the central points with two central examples from biology. The first thing to say is that, on the face of (...) it, some doctrine of the social construction of science must self-evidently be true. The notion of science as progressing through the efforts of solitary geniuses may have had some plausibility in the seventeenth century, but it has none today. Science is a massively cooperative, social, enterprise. And surely it is constructed. Scientific knowledge doesn't grow on trees; it is produced through hard work by human agents. Putting these two banal points together we conclude that science is socially constructed. (shrink)

This paper compares human diversity with biological diversity generally. Drawing on the pluralistic perspective on biological species defended in earlier work (2002, chs. 3 and 4), I argue that there are useful parallels to be drawn between human and animal kinds, as there are between their respective sources in cultural evolution and evolution generally. This view is developed in opposition to the insistence by sociobiologists and their successors on minimizing the significance of culture. The paper concludes with a discussion of (...) the relation between cultural difference and individual difference, and the relation of the latter to conceptions of human freedom. (shrink)
