If we arrange in chronological order the various statements Darwin made about God, creation, design, plan, law, and so forth, that I have discussed, there emerges a picture of a consistent development in Darwin's religious views from the orthodoxy of his youth to the agnosticism of his later years. Numerous sources attest that at the beginning of the Beagle voyage Darwin was more or less orthodox in religion and science alike.78 After he became a transmutationist early in 1837, he concluded (...) that the doctrine of secondary causes must be extented even to the history of life and that after the first forms of life were created, there was no further need for divine intervention, except where man was concerned. Man's body, he thought, was produced by the process of transmutation, but he believed for a time that man's soul was “superadded.” By mid-1838 he had become convinced that nothing, after the creation of life, was due to miracles. God works only through laws, which are capable of producing “every effect of evey kind which surrounds us.” The existence of man, the idea of God in man's mind, and the harmony of the whole system were in his eyes prearranged goals of deterministic laws imposed by God. Such a conception excludes the miracles on which Christianity depends; but it is not possible to say whether Darwin's loss of Christian faith, which occurred at about this same time, preceded and made possible his “materialism” or was rather caused or hastened by it.79 In the weeks after his reading of Malthus, Darwin's belief in a plan of creation gave way to the belief that God created matter and life and designed their laws, leaving the details, however, to the workings of chance. This remained his view until the 1860s.There is no exact parallel between this development of Darwin's religious views and the development of his ideas on evolution, but there is a general correspondence. When he believed in a plan of creation, Darwin's theory of transmutation did not depend on struggle or the selection of chance variations. Adaptation was, for him, an automatic response to environmental chance. From late 1838 to 1859 he believed in designed laws and chance, and this belief, too, has its parallel in his theory. The element of chance in natural selection meant that there could be no detailed plan,in which even man's idea of God would be a necessary outcome of nature's laws (man himself is not a necessary outcome of the working of natural selection).80 But Darwin still believed nature was programmed to achieve certain general ends. We might say that he believed in a general, though not a special, teleology. Natural selection was for him a law to maximize utility, creating useful organs, retaining vestiges for future use. For many years it was a law designed to produce organisms perfectly adapted to their environments. Only later did Darwin come to doubt even this sort of design in nature.81 One way of describing the development of Darwin's evolutionary thought is to say that it shows a gradual abandoning of his “theistic” assumptions, so that by the late 1860s his theory was informed to a slighter extent by notions of purpose and design than it was in 1838 or 1844 or 1859.

Human intentional action, including the design and use of artifacts, involves the prior mental representation of the goal (end) and the means to achieve that goal. This representation is part of the efficient cause of the action, and thus can be used to explain both the action and the achievement of the end. This is intentional teleological explanation. More generally, teleological explanation that depends on the real existence of a representation of the goal (and the means to achieve it) can (...) be called representational teleological explanation. Such explanations in biology can involve both external representations (e.g., ideas in the mind of God) and internal representations (souls, vital powers, entelechies, developmental programs, etc.). However, another type of explanation of intentional action (or any other process) is possible. Given that an action achieving a result occurs, the action can be explained as fulfilling the necessary conditions (means) for that result (end), and, reciprocally, the result explained by the occurrence of those necessary conditions. This is conditional teleological explanation. For organisms, natural selection is often understood metaphorically as the designer, intentionally constructing them for certain ends. Unfortunately, this metaphor is often taken rather too literally, because it has been difficult to conceive of another way to relate natural selection to the process of evolution. I argue that combining a conditional teleological explanation of organisms and of evolution provides such an alternative. This conditional teleology can be grounded in existence or survival. Given that an organism exists, we can explain its existence by the occurrence of the necessary conditions for that existence. This principle of the 'conditions for existence' was introduced by Georges Cuvier in 1800, and provides a valid, conditional teleological method for explaining organismal structure and behavior. From an evolutionary perspective, the conditions for existence are the range of boundary conditions within which the evolutionary process must occur. Moreover, evolutionary change itself can be subjected to conditional teleological explanation, because natural selection theory is primarily a theory about the relation between the conditions for the existence of organisms and the conditions for the existence of traits in populations. I show that failure to distinguish representational from conditional teleological explanation has confused previous attempts to clarify the relation of teleology to biology. (shrink)

Jablonka & Lamb (J&L) have presented a number of different possible mechanisms for finessing design. The extra-genetic nature of these mechanisms has led them to challenge orthodox neo-Darwinian views. However, these mechanisms are for calibration and have been designed by natural selection. As such, they add detail to our knowledge, but neo-Darwinism is sufficiently resourced to account for them.

Abstract Daniel Dennett advocates the use of the intentional stance in adaptationist biology and in cognitive ethology. He sees intentional system theory as closely related to decision theory and game theory. In biological decision and game theory models, nature ?chooses? the strategy by which the animal chooses a course of action. The design of the animal imposes constraints on the model. For Dennett, by contrast, the description of nature's rationale imposes constraints on the design of the animal. Dennett's oversimplified conception (...) of nature's rationale undermines the usefulness of the intentional stance as a tool in cognitive ethology. Intentional system theory can be made more useful in investigating animal cognition by modifying its application to questions of biological function. (shrink)

Darwin's theory of evolution by natural selection provided the first, and only, causal-mechanistic account of the existence of adaptations in nature. As such, it provided the first, and only, scientific alternative to the “argument from design”. That alone would account for its philosophical significance. But the theory also raises other philosophical questions not encountered in the study of the theories of physics. Unfortunately the concept of natural selection is intimately intertwined with the other basic concepts of (...) evolutionary theory—such as the concepts of fitness and adaptation —that are themselves philosophically controversial. Fortunately we can make considerable headway in getting clear on natural selection without solving all of those outstanding problems. (shrink)

Even today, a century after the publication of the “Origin of Species”, current zoological literature often reveals an insufficient grasp of the implications of the now generally accepted view that it is natural selection that confers direction on the evolutionary process.This is, in part, due to a reaction against oversimplified teleology and against Lamarckism. In rejecting Lamarck's thesis that the activities of an animal directly affect its hereditary characters it is frequently assumed that this implies that such activities (...) are irrelevant to the study of evolution. This is a non-sequitur, for activities may affect evolution not directly, through heredity, but indirectly, by influencing the direction of the selective forces impinging on the organism. Reasons are given for concluding that changes in habits and behaviour frequently precede structural change and, in fact, determine the direction of the latter.As an example of a concept which deserves a more evolutionary treatment than it commonly receives, the subject of neoteny is considered. It appears that failure to think in terms of the selective forces involved has frequently led to error. An analysis in functional terms is made of the theory that the chordates represent secondarily glorified sea-squirts and it is concluded that this idea is unlikely to be correct. The characteristics of man that are commonly considered to be neotenous are also discussed. It is concluded that a facile and unanalytical application of the label “neoteny” to many of the evolutionary changes involved has tended to obscure rather than to clarify their significance: the neotenous features of man are not those that have been of primary importance in human evolution, but are secondary to the acquisition of new characters which are not to be found in either the adult or the young stages of any other primate.Aujourd'hui, un siècle après l'apparition de l'Originedes Espèces, la conviction est presque générale que la sélection naturelle dirige le procès de l'évolution. Néanmoins, les publications zoologiques actuelles révèlent souvent une compréhension insuffisante de ce qui en résulte.Ceci doit en partie être considéré comme réaction contre une téléologie simpliste et contre le Lamarckisme. En rejetant la thèse de Lamarck, que les activités d'un animal ont une influence directe sur ses caractéristiques héréditaires, on admet fréquemment que de pareilles activités n'ont rien à voir avec l'étude le l'évolution. Cependant, une telle conclusion n'est pas justifiée, car les activités peuvent influer sur l'évolution non pas directement, par la voie de l'hérédité, mais indirectement en agissant sur la direction des forces sélectives que l'organisme rencontre. Des raisons ont été données qui mènent à conclure que des changements dans les habitudes et dans le comportement précèdent maintes fois le changement structural et même déterminent la direction de celui-ci.Comme exemple d'un concept qui mérite un traitement plus évolutionniste qu'il ne reçoive en général, la néoténie a été examinée. Il paraît que l'on a fait beaucoup d'erreurs en ne tenant pas compte des forces sélectives engagées. Une analyse au pointde-vue de la fonction a été appliquée à la théorie que les chordées ne sont que des ascidies néoténiques transfigurées par après, et il s'ensuit que cette idée n'est probablement pas correcte. Aussi les caractéristiques de l'homme généralement regardées comme neoténiques ont été discutées. Il en résulte que, en désignant légèrement et sans analyse plusieurs changements évolutionnaires comme néoténie, on a plutôt obsurci qu'éclairci leur signification. Ce ne sont pas les traits néoteniques de l'homme qui ont joué le rôle principal dans l'évolution humaine; au contraire, ils n'apparaissent qu'après l'acquisition de quelques nouvelles caractéristiques qui ne se trouvent ni dans l'adulte ni dans les phases plus jeunes des autres primates.Sogar heutzutage, ein Jahrhundert nach dem Erscheinen der „Origin of Species”, zeigt die jetzige zoologische Literatur oft eine unzulängliche Einsicht in die Folgerungen, zu denen die jetzt allgemein akzeptierte Annahme leitet, dass die natürliche Selektion die Richtung des Evolutionsprozesses bedingt.Dies ist teilweise zu sehen als eine Reaktion gegen eine einseitige Teleologie und gegen das Lamarckismus. Bei der Ablehnung der TheseLamarck's, dass die Aktivitäten eines Tieres einen direkten Einfluss ausüben auf seine erbliche Konstitution, nimmt man oft an, dass dies bedeutet, dass derartige Aktivitäten demnach nichts zur Sache tun bei dem Studium der Evolution. Zu einer derartigen Konklusion ist man jedoch nicht berechtigt, denn, obwohl die Aktivitäten die Evolution nicht direkt beeinflussen können mittels der Erblichkeit, so können sie dies jedoch indirekt, weil sie die Richtung der selektiven Kräfte, welche auf das Organismus einwirken, bestimmen. Es werden Argumente gegeben, welche die Konklusion rechtfertigten, dass Änderungen in Gewohnheit und Verhalten oft Strukturänderungen vorhergehen und tatsächlich die Richtung dieser letztgenannten bestimmen. Die Neotenie wirdt als ein Beispiel eines Begriff betrachtet, welcher eine mehr evolutionäre Behandlung verdient als bisher geschehen ist. Es ergibt sich dass man viele Irrtümer hat gemacht, indem man den betreffenden selektiven Kräften keine Rechnung getragen hat. Eine Analyse der Theorie, welche die Chordaten als neotenische Ascidien betrachtet, wird von einem funktionellen Gesichtspunkt aus durchgeführt. Daraus scheint der Schluss berechtigt, dass diese Theorie falsch ist. Auch werden die menschlichen Kennzeichen, welche gewöhnlich als neotenische betrachtet werden, besprochen. Die Konklusion lautet, dass, wenn man leichtfertig und ohne genügende Analyse den Zettel „Neotenie“ für mancherlei evolutive Änderungen anwendet, man die richtige Bedeutung dieser Erscheinung vielmehr verdunkelt als aufklärt: nicht die neotenische Kennzeichen des Menschen sind am wichtigsten in seiner Evolution; in Gegenteil sie erscheinen nur sekundär, nachdem die neuen Kennzeichen, welche sich weder in den Erwachsenen noch in den jüngeren Stadien von den anderen Primaten finden lassen, erschienen sind.

The argument from design is best understood as a likelihood inference. Its Achilles heel is our lack of knowledge concerning the aims and abilities that the putative designer would have; in consequence, it is impossible to determine whether the observations are more probable under the design hypothesis than they are under the hypothesis of chance. Hypotheses about the role played by natural selection in the history of life also can be evaluated within a likelihood framework, and here too (...) there are auxiliary assumptions that need to be in place if the likelihoods of selection and chance are to be compared. I describe some problems that arise in connection with the project of obtaining independent evidence concerning those auxiliary assumptions. (shrink)

Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every tenet of Darwinian theory – that it shows no genetic variation, could not exist in any (...) intermediate forms, confers no selective advantage, and would require more evolutionary time and genomic space than is available. We examine these arguments and show that they depend on inaccurate assumptions about biology or language or both. Evolutionary theory offers clear criteria for when a trait should be attributed to natural selection: complex design for some function, and the absence of alternative processes capable of explaining such complexity. Human language meets these criteria: Grammar is a complex mechanism tailored to the transmission of propositional structures through a serial interface. Autonomous and arbitrary grammatical phenomena have been offered as counterexamples to the position that language is an adaptation, but this reasoning is unsound: Communication protocols depend on arbitrary conventions that are adaptive as long as they are shared. Consequently, language acquisition in the child should systematically differ from language evolution in the species, and attempts to analogize them are misleading. Reviewing other arguments and data, we conclude that there is every reason to believe that a specialization for grammar evolved by a conventional neo-Darwinian process. (shrink)

What is natural selection? I address this question by exploring the relation between two debates: Is natural selection a mechanism? Is natural selection a causal or a statistical theory? I argue that the first can be assessed only relative to a model and that, following the second, there are two fundamentally different and independent kinds of models, Modern-Synthesis and Darwinian models. MS-models, I argue, are not mechanistic even if they are causal. D-models, in contrast, (...) are mechanistic. A causal-mechanistic interpretation of D-models is thus compatible with a statistical interpretation of MS-models. Natural selection, I conclude, lacks a single, unifying nature. (shrink)

Recent papers by a number of philosophers have been concerned with the question of whether natural selection is a causal process, and if it is, whether the causes of selection are properties of individuals or properties of populations. I shall argue that much confusion in this debate arises because of a failure to distinguish between causal productivity and causal relevance. Causal productivity is a relation that holds between events connected via continuous causal processes, while causal relevance is (...) a relationship that can hold between a variety of different kinds of facts and the events that counterfactually depend upon them. I shall argue that the productive character of natural selection derives from the aggregation of individual processes in which organisms live, reproduce and die. At the same time, a causal explanation of the distribution of traits will necessarily appeal both to causally relevant properties of individuals and to causally relevant properties that exist only at the level of the population.

I try to focus our differences by examining the relation between what Dennett has termed "the intentional stance" and "the design stance." Dennett takes the intentional stance to be more basic than the design stance. Ultimately it is through the eyes of the intentional stance that both human and natural design are interpreted, hence there is always a degree of interpretive freedom in reading the mind, the purposes, both of Nature and of her children. The reason, or at least (...) a reason, is that intentional interpretation is holistic, hence indeterminate, for the kinds of reasons given by Davidson and Quine. In contrast, I take the design stance to be more basic than the intentional stance. Intentional attributions express our best guesses about the locations of effects of certain kinds of natural design. And although there is often indeterminacy, ambiguity, or vagueness concerning what it is that natural selection (or learning) has selected for, these indeterminacies and vaguenesses are local, not holistic. There is reason to suppose that the better portion of Nature's purposes and the intentional states of her children are determinate in content within quite closely defined limits. I propose to defend this position as well as I can, so as to call from Dennett his own views on precisely where our paths separate (if they really do). (shrink)

In evolutionary biology and ecology, ontological and epistemological perspectives based on the replicator and the interactor have become the background that makes it possible to transcend traditional biological levels of organization and to achieve a unified view of evolution in which replication and interaction are fundamental operating processes. Using the transactional perspective proposed originally by John Dewey and Arthur Fisher Bentley, a new ontological and methodological category is proposed here: the transactor. The transactional perspective, based on the concept of the (...) transactor, bridges the dichotomy between organisms and environment that characterizes the interactional perspective on evolution and provides epistemological support for the emergentist, systemic view of evolutionary and developmental processes.

he following kind of incident has occurred over and over again, ever since Darwin. An evolutionist, browsing through some pre-Darwinian tome in natural history, comes upon a description of natural selection. Aha, he says; I have found something important, a proof that Darwin wasn't original. Perhaps I have even discovered a source of direct and nefarious pilfering by Darwin! In the most notorious of these claims, the great anthropologist and writer Loren Eiseley thought that he had (...) detected such an anticipation in the writings of Edward Blyth. Eiseley laboriously worked through the evidence that Darwin had read (and used) Blyth's work and, making a crucial etymological mistake along the way, finally charged that Darwin may have pinched the central idea for his theory from Blyth. He published his case in a long article (Eiseley, 1959), later expanded by his executors into a posthumous volume entitled "Darwin and the Mysterious Mr. X" (1979). (shrink)

The concept of fitness has generated a lot of discussion in philosophy of biology. There is, however, relative agreement about the need to distinguish at least two uses of the term: ecological fitness on the one hand, and population genetics fitness on the other. The goal of this paper is to give an explication of the concept of ecological fitness by providing a reconstruction of the theory of natural selection in which this concept was framed, that is, based (...) on the way the theory was put to use in Darwin’s main texts. I will contend that this reconstruction enables us to account for the current use of the theory of natural selection. The framework presupposed in the analysis will be that of metatheoretical structuralism. This framework will provide both a better understanding of the nature of ecological fitness and a more complete reconstruction of the theory. In particular, it will provide what I think is a better way of understanding how the concept of fitness is applied through heterogeneous cases. One of the major advantages of my way of thinking about natural selection theory is that it would not have the peculiar metatheoretical status that it has in other available views. I will argue that in order to achieve these goals it is necessary to make several concepts explicit, concepts that are frequently omitted in usual reconstructions. (shrink)

Until the last years of his life, Charles Darwin had actually never read Aristotle. The sole reference he makes to his naturalist forebear in _On the Origin of Species_ came in an addition to the fourth edition, published in 1866, in which he mistakenly refers to Aristotle’s summation of Empedocles’ position at _Physica_ II 8, as Aristotle’s own, and notes that ‘we see here the principle of natural selection shadowed forth’ (while disputing the specific scientific point Aristotle – (...) though actually Empedocles – was supposedly making). So when his friend William Ogle, a minor scientist and physician, and an evangelist Christian, published a translation of Aristotle’s _De partibus animalium_ in 1882 and sent a copy to Darwin, he was able to declare that he felt “some self-importance in thus being a kind of formal introducer of the father of Naturalists [Aristotle] to his great modern successor [Darwin].” Ogle, who despite his religious inclinations was nevertheless a strong proponent of Darwin’s theories, did not agree with Aristotle’s scientific theories – not least because Aristotle’s teleological model of animal development, which had been adopted as a model by many post-classical Christian scientists and theologians for centuries, was dealt a serious blow by Darwin’s theory of natural selection. So it is perhaps surprising to see Ogle produce a translation of one of Aristotle’s major biological treatises. By looking at key passages of Aristotle and Ogle’s translation, this paper will examine the reasons for Ogle’s curious choice to publish his work, setting it into the wider scientific, and Darwinian, context of late-nineteenth century Britain, and explaining how Aristotle the teleologist was used by Ogle to re-enforce Darwin’s position as a modern natural historian.

We review the various factors that limit adaptation by natural selection. Recent discussion of constraints on selection and, conversely, of the factors that enhance “evolvability”, have concentrated on the kinds of variation that can be produced. Here, we emphasise that adaptation depends on how the various evolutionary processes shape variation in populations. We survey the limits that population genetics places on adaptive evolution, and discuss the relationship between disparate literatures. BioEssays 22:1075–1084, 2000. © 2000 John Wiley & (...)

One approach to assess the explanatory power of natural selection is to ask what type of facts it can explain. The standard list of explananda includes facts like trait frequencies or the survival of particular organisms. Here, I argue that this list is incomplete: natural selection can also explain a specific kind of individual-level fact that involves traits. The ability of selection to explain this sort of fact vindicates the explanatory commitments of empirical studies (...) on microevolution. Trait facts must be distinguished from a closely related kind of fact, that is, the fact that a particular individual x has one trait rather than another. Whether or not selection can explain the latter type of fact is highly controversial. According to the so-called ‘Negative View’ it cannot be explained by selection. I defend the Negative View against Nanay’s objection. (shrink)

Empty judgements appear to be about something, and inaccurate judgements to report something. Naturalism tries to explain these appearances without positing non-real objects or states of affairs. Biological naturalism explains that the false and the empty are tokens which fail to perform the function proper to their biological type. But if truth is a biological 'supposed to', we should expect designs that achieve it only often enough. The sensory stimuli which trigger the frog's gulp-launching signal may be a poor guide (...) to the signal's content. Teleosemantics should be anti-verificationist. (shrink)

While a great deal of abuse has been directed at intelligent design theory (ID), its starting point is a fact about biological organisms that cries out for explanation, namely "specified complexity" (SC). Advocates of ID deploy three kind of argument from specified complexity to the existence of a designer: an eliminative argument, an inductive argument, and an inference to the best explanation. Only the first of these merits the abuse directed at it; the other two arguments are worthy of (...) respect. If they fail, it is only because we have a better explanation of SC, namely Darwin's theory of evolution by natural selection. (shrink)

Designer babies are often presented in the popular media as a kind of apocalyptical spectre of things to come in a brave new world where reproduction is the province of white coated scientists and potential parents in pursuit of trophy children. In this realm physical, intellectual, and social perfection is sought through the manipulation of genes and selection of favoured traits and attributes to the detriment of individuals who cannot compete and of society more generally through the loss (...) of natural selection. It is therefore a pleasure to discover a short readable book that sets out the discussion and its many nuances in concise and accurate terms that will be accessible to all and should help to dispel some of these science fiction myths through scholarly debate.This volume is part of a collection of books under the title Debating Matters that sprang out of a series of public debates organised by the Institute of Ideas. The conferences were intended to reinvigorate debate and the contestation of ideas and contemporary issues the Institute regards as “too frequently sidelined”. The arguments are presented by an authoritative who’s who of commentators who offer their own insightful readings of various aspects of the debate.

In lieu of an abstract, here is a brief excerpt of the content:Human Nature in Nineteenth-Century British Novels:Doing the MathJoseph Carroll, Jonathan Gottschall, John A. Johnson, and Daniel J. KrugerIThree broad ambitions animate this study. Building on research in evolutionary social science, we aimed (1) to construct a model of human nature—of motives, emotions, features of personality, and preferences in marital partners; (2) use that model to analyze some specific body of literary texts and the responses of readers to those (...) texts, and (3) produce data—information that could be quantified and could serve to test specific hypotheses about those texts.Evolutionary social science is still in the process of constructing a full and adequate model of human nature. Evolutionary social scientists know much already about how human reproductive behavior and human sociality fit into the larger pattern of human evolution. They still have much to learn, though, about the ways literature and the other arts enter into human nature. Our model of human nature draws on our knowledge of imaginative culture, integrates that knowledge with evolutionary theories of culture, and produces data that enable us to draw conclusions on an issue of broad significance for both literary study and evolutionary social science: the adaptive function of literature and the other arts.1In order to make advances in knowledge, it is necessary to choose some particular subject. Genetics is a basic science that applies to all organisms, but geneticists first got an empirical fix on their subject by focusing minutely, with Mendel, on peas, and, with Morgan, on fruit flies. In place of peas and flies, we have taken as our subject British novels of [End Page 50] the longer nineteenth century (Austen to Forster). As a literary topic, the subject is fairly broad, but our theoretical and methodological aims ultimately extend well beyond the specialist fields of British novels, the nineteenth century, British literature, narrative fiction, or even literary scholarship generally. This study is designed to engage the attention of literary scholars in all fields and also to engage the attention of social scientists. If it achieves its aims, this study would help persuade literary scholars that empirical methods offer rich opportunities for the advancement of knowledge about literature, and it would help persuade social scientists that the quantitative study of literature can shed important light on fundamental questions of human psychology and human social interaction. Our own research team combines these two prospective audiences. Two of us (Carroll and Gottschall) have been trained primarily as literary scholars, and two of us (Johnson and Kruger) primarily as social scientists.The focal point for this study is "agonistic" structure: the organization of characters into protagonists, antagonists, and minor characters. The central question in the study is this: does agonistic structure reflect evolved dispositions for forming cooperative social groups? Suppressing or muting competition within a social group enhances group solidarity and organizes the group psychologically for cooperative endeavor. Our chief hypothesis was that protagonists and good minor characters would form communities of cooperative endeavor and that antagonists would exemplify dominance behavior. If this hypothesis proved correct, the ethos reflected in the agonistic structure of the novels would replicate the egalitarian ethos of hunter-gatherers, who stigmatize and suppress status-seeking in potentially dominant individuals. If suppressing dominance in hunter-gatherers fulfills an adaptive social function, and if agonistic structure in the novels engages the same social dispositions that animate hunter-gatherers, our study would lend support to the hypothesis that literature fulfills an adaptive social function.2One of our chief working hypotheses is that when readers respond to characters in novels, they respond in much the same way, emotionally, as they respond to people in everyday life. They like or dislike them, admire them or despise them, fear them, feel sorry for them, or are amused by them. In writing fabricated accounts of human behavior, novelists select and organize their material for the purpose of generating such responses, and readers willingly cooperate with this purpose. They participate vicariously in the experiences depicted and form personal opinions about the qualities of the characters. Authors and readers [End Page 51] thus collaborate in producing a simulated experience of emotionally responsive evaluative judgment. If agonistic structure is a... (shrink)

What we have learnt in the last six or seven decades about virtual machinery, as a result of a great deal of science and technology, enables us to offer Darwin a new defence against critics who argued that only physical form, not mental capabilities and consciousness could be products of evolution by natural selection. The defence compares the mental phenomena mentioned by Darwin’s opponents with contents of virtual machinery in computing systems. Objects, states, events, and processes in virtual (...) machinery which we have only recently learnt how to design and build, and could not even have been thought about in Darwin’s time, can interact with the physical machinery in which they are implemented, without being identical with their physical implementation, nor mere aggregates of physical structures and processes. The existence of various kinds of virtual machinery (including both “platform” virtual machines that can host other virtual machines, e.g. operating systems, and “application” virtual machines, e.g. spelling checkers, and computer games) depends on complex webs of causal connections involving hardware and software structures, events and processes, where the specification of such causal webs requires concepts that cannot be defined in terms of concepts of the physical sciences. That indefinability, plus the possibility of various kinds of self-monitoring within virtual machinery, seems to explain some of the allegedly mysterious and irreducible features of consciousness that motivated Darwin’s critics and also more recent philosophers criticising AI. There are consequences for philosophy, psychology, neuroscience and robotics. (shrink)

Today’s education system needs to be global. ‘World Class Education’ involves a globally accepted high standard of education. Every country needs an increasing number of highly educated people and skilled professionals in order to integrate into the globalization process. These professionals include scholars, philosophers and leaders with vision. Leaders are our human capital. The state must provide opportunities for higher education to create human capital that meets global standards. The overall development of a society is largely determined by the quality (...) of its education, especially higher education. A well-educated, well-trained population could propel a nation towards rapid economic growth. Despite lack of natural resources, countries such as Japan, Korea and Singapore have made rapid economic progress. This was because they invested heavily in education and training. On the other hand, countries such as Nigeria or Congo, despite enormous natural resources, are poor and backward because of large-scale illiteracy and lack of skilled workforce. The aim of education is to create well-trained, competent and progressive individuals who can perform all kinds of tasks and take on a lot of responsibilities. Higher education is the stage of education that takes place at the post-secondary level, and is provided mostly and most meaningfully by universities. A university introduces its students to discussions and debates that prevail in various disciplines and fields of knowledge. The objective of a university is not only to create and disseminate knowledge but also to develop human resources that will accelerate the socio-economic development of the nation. This is possible only when the employees working in these universities are motivated and empowered. To achieve this objective, universities must restructure and redesign their HRD practices and processes. In this background, the present article analyzes the existing HRD practices and processes in 10 leading universities in India and how should these universities go about transforming their HR systems and mechanisms to meet the rapidly changing environmental demands. The research approach and methodology adopted to carry out this study includes collection of primary and secondary data. Primary data has been collected by administering a well-structured and well-designed questionnaire on HRD climate survey developed by XLRI Jamshedpur (India). The questionnaire had been administered to 1,000 respondents selected from the 10 leading universities of India. Data from both the sources were analyzed statistically by applying various statistical tools and techniques to find the conclusions, based on which the guidelines, recommendations and policy implications were made for the improvement of HRD practices in the universities.

Arguing About Human Nature covers recent debates--arising from biology, philosophy, psychology, and physical anthropology--that together systematically examine what it means to be human. Thirty-five essays--several of them appearing here for the first time in print--were carefully selected to offer competing perspectives on 12 different topics related to human nature.

When social scientists began employing evolutionary game theory (EGT) in their disciplines, the question arose what the appropriate interpretation of the formal EGT framework would be. Social scientists have given different answer, of which I distinguish three basic kinds. I then proceed to uncover the conceptual tension between the formal framework of EGT, its application in the social sciences, and these three interpretations. First, I argue that EGT under the biological interpretation has a limited application in the social sciences, chiefly (...) because strategy replication often cannot be sensibly interpreted as strategy bearer reproduction in this domain. Second, I show that alternative replication mechanisms imply interpersonal comparability of strategy payoffs. Giving a meaningful interpretation to such comparisons is not an easy task for many social situations, and thus limits the applicability of EGT in this domain. Third, I argue that giving a new interpretation both to strategy replication and selection solves the issue of interpersonal comparability, but at the costs of making the new interpretation incompatible with natural selection interpretations of EGT. To the extent that social scientists seek such a natural selection interpretation, they face a dilemma: either face the challenge that interpersonal comparisons pose, or give up on the natural selection interpretation. By identifying these tensions, my analysis pleas for greater awareness of the specific purposes of EGT modelling in the social sciences, and for greater sensitivity to the underlying microstructure on which the evolutionary dynamics and other EGT solution concepts supervene.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Virtue, Nature, and Moral Agency in the XunziKurtis HagenVirtue, Nature, and Moral Agency in the Xunzi. Edited, with introduction, by T. C. Kline III and Philip J. Ivanhoe. Indianapolis: Hackett Publishing Company, 2000. Pp. xvii + 268.Virtue, Nature, and Moral Agency in the Xunzi, edited by T. C. Kline III and Philip J. Ivanhoe, is an anthology that has much to recommend it. It brings together several seminal (...) papers on Xunzi by established and distinguished scholars of Chinese philosophy, such as Antonio S. Cua, D. C. Lau, David S. Nivison, and Henry Rosemont, Jr. It also includes contributions from relative newcomers, who focused their dissertations on Xunzi's philosophy, namely T. C. Kline III and Eric Hutton. While most of these essays have been previously published, some appear in print for the first time in this volume. There is also a succinct introduction, name and subject indexes, and a targeted bibliography, which may serve as a reading list for those interested in supplementing their study of Xunzi. Another nicety is that references to passages in the Xunzi in older articles have been updated to include John Knoblock's translation1 as well as A Concordance to the Xunzi,2 and romanizations have been standardized to pinyin. [End Page 434]For the most part, the title Virtue, Nature, and Moral Agency in the Xunzi accurately represents the most prominent subject matter of the book. However, by "nature" what is meant is apparently "human nature," if that is an adequate translation for the concept Xunzi designates with the character xing. Xunzi's view of tian (the propensities of nature, the heavens) is not prominently discussed.3 Most of the essays, chapters 4 through 11 (the final chapter), deal extensively if not primarily with understanding Xunzi's conception of human nature. Chapters 5 through 7 are tied even closer together under the theme of moral agency (more on their connection below). Virtue is the topic of chapter 3 and plays a role in chapters 4 and 7.Although the first two chapters seem not to fall neatly within these categories, Henry Rosemont, Jr.'s contribution, "State and Society in the Xunzi: A Philosophical Commentary," seems an appropriate choice for the lead chapter of this collection. A sweeping polemic in defense of Xunzi's political philosophy, this seminal essay demonstrates the philosophical strength and potential relevance of Xunzi's thought. Specifically, Rosemont argues that Xunzi's political system is no less "reasonable" than democracy, and that while Xunzi advocates what Karl Popper would call a "closed society," Xunzi's system is defensible against Popper's critique of such societies.4The second chapter, "Ethical Uses of the Past in Early Confucianism: The Case of Xunzi," is authored by Antonio S. Cua, who has been a consistent contributor to the understanding of Xunzi's philosophy for more than twenty years. A collection of essays on Xunzi would be incomplete without Cua's work being represented. However, given the themes of the book, it is not entirely clear why this particular piece was selected. While Cua has written on both human nature and virtue in the Xunzi, this essay only tangentially addresses the theme of virtue. Nevertheless, it exemplifies the kind of careful scholarship characteristic of Cua's work, and there is something to be said for an anthology like this to exhibit breadth as well as focus. In his contribution, Cua analyzes Xunzi's appeal to history in terms of its "pedagogical function," "rhetorical function," "elucidative function," and "evaluative function."In chapter 3, "Virtues in Xunzi's Thought," Jonathan W. Schofer offers a lucid depiction of Xunzi's moral theory as a kind of virtue theory, despite the lack of any systematic analysis on Xunzi's part of a specific set of virtues. He then suggests that, given Xunzi's theory and goals, the omission of any analysis of specific virtues may have been deliberate.The last eight chapters deal extensively with the issue of human nature. Chapter 4, "Xunzi: Morality as Psychological Constraint," by Joel J. Kupperman, compares Xunzi's and Mencius' conceptions of human nature. Kupperman argues that, unlike Mencius, Xunzi does not really have a "view of human... (shrink)

Conversational interfaces are becoming ubiquitous in an increasing number of application domains as Artificial Intelligence, Natural Language Processing and Machine Learning methods associated with the recognition, understanding and generation of natural language advance by leaps and bounds. However, designing the dialog model of these systems is still a very demanding task requiring a great deal of effort given the number of information sources to be considered related to the analysis of user utterances, interaction context, information repositories, etc. In (...) this paper, we present a general framework for increasing the quality of the system responses by combining a statistical dialog management technique and a deep learning-based intention recognizer that allow replacing the system responses initially selected by the statistical dialog model with other presumably better candidates. This approach is portable to different task-oriented domains, a diversity of methodologies for dialog management and intention estimation techniques. We have evaluated our two-step proposal using two conversational systems, assessed several intention recognition methodologies and used the developed modules to dynamically select the system responses. The results of the evaluation show that the proposed framework achieves satisfactory results by making it possible to reduce the number of non-coherent dialog responses by replacing them by more coherent alternatives.

Is the adaptive complexity of living organisms the result of evolutionary processes alone? or does it give evidence of intentional design? Michael Ruse appears to argue that we can have it either way. As a scientist I find the argument from design unnecessary. Yet it has great appeal to humans, whose behavior is largely intentional and who look for patterns in events and for the intentions that may have produced them.

Accounts of the concepts of function and dysfunction have not adequately explained what factors determine the line between low‐normal function and dysfunction. I call the challenge of doing so the line‐drawing problem. Previous approaches emphasize facts involving the action of natural selection (Wakefield 1992a, 1999a, 1999b) or the statistical distribution of levels of functioning in the current population (Boorse 1977, 1997). I point out limitations of these two approaches and present a solution to the line‐drawing problem that builds (...) on the second one. (shrink)

Both biologists and philosophers often make use of simple verbal formulations of necessary and sufficient conditions for evolution by natural selection (ENS). Such summaries go back to Darwin's Origin of Species (especially the "Recapitulation"), but recent ones are more compact.1 Perhaps the most commonly cited formulation is due to Lewontin.2 These summaries tend to have three or four conditions, where the core requirement is a combination of variation, heredity, and fitness differences. The summaries are employed in several ways. (...) First, they are often used in pedagogical contexts, and in showing the coherence of evolutionary theory in response to attacks from outside biology. Second, they are important in discussions of extensions of evolutionary principles to new domains, such as cultural change. The summaries also have intrinsic scientific and philosophical interest as attempts to capture some core principles of evolutionary theory in a highly concise way. Despite their prominence, both the proper formulation and status of these summaries are unclear. Standard formulations are subject to counterexamples, and their relations to formal models of evolutionary change are not straightforward. Here I look closely at these verbal summaries, and at how they relate to formal models. Are the summaries merely rough approximations that have no theoretical role of their own? Perhaps they could operate as theoretical statements in Darwin's time, but have now been superseded by more exact treatments. (shrink)

Natural selection is commonly interpreted as the fundamental mechanism of evolution. Questions about how selection theory can claim to be the all-sufficient explanation of evolution often go unanswered by today's neo-Darwinists, perhaps for fear that any criticism of the evolutionary paradigm will encourage creationists and proponents of intelligent design.In Biological Emergences, Robert Reid argues that natural selection is not the cause of evolution. He writes that the causes of variations, which he refers to as (...) class='Hi'>natural experiments, are independent of natural selection; indeed, he suggests, natural selection may get in the way of evolution. Reid proposes an alternative theory to explain how emergent novelties are generated and under what conditions they can overcome the resistance of natural selection. He suggests that what causes innovative variation causes evolution, and that these phenomena are environmental as well as organismal.After an extended critique of selectionism, Reid constructs an emergence theory of evolution, first examining the evidence in three causal arenas of emergent evolution: symbiosis/association, evolutionary physiology/behavior, and developmental evolution. Based on this evidence of causation, he proposes some working hypotheses, examining mechanisms and processes common to all three arenas, and arrives at a theoretical framework that accounts for generative mechanisms and emergent qualities. Without selectionism, Reid argues, evolutionary innovation can more easily be integrated into a general thesis. Finally, Reid proposes a biological synthesis of rapid emergent evolutionary phases and the prolonged, dynamically stable, non-evolutionary phases imposed by natural selection. (shrink)

Is the theory of evolution by means of natural selection a tautology? This book explores the explanatory structure of Darwin’s theory at a time when selectionist explanations are being brought forward to explain a wider and wider range of phenomena.

According to the standard formulation, natural selection requires variation, differential fitness, and heritability. I argue that this formulation is inadequate because it fails to distinguish natural selection from artificial selection, intelligent design, forward-looking orthogenetic selection, and adaptation via the selection of nonrandom variation. I suggest adding a _no teleology_ condition. The no teleology condition says that the evolutionary process is not guided toward an endpoint represented in the mind of an agent, variation is (...) produced randomly with respect to adaptation, and selection pressures are not forward looking.

For evolution by natural selection to occur it is classically admitted that the three ingredients of variation, difference in fitness and heredity are necessary and sufficient. In this paper, I show using simple individual-based models, that evolution by natural selection can occur in populations of entities in which neither heredity nor reproduction are present. Furthermore, I demonstrate by complexifying these models that both reproduction and heredity are predictable Darwinian products (i.e. complex adaptations) of populations initially lacking (...) these two properties but in which new variation is introduced via mutations. Later on, I show that replicators are not necessary for evolution by natural selection, but rather the ultimate product of such processes of adaptation. Finally, I assess the value of these models in three relevant domains for Darwinian evolution. (shrink)

I argue that our general disposition to make moral judgments and our core moral intuitions are likely the product of social selection—a kind of gene–culture coevolution driven by the enforcement of collectively agreed-upon rules. Social selection could potentially track mind-independent moral truth by a process that I term realist social selection: our ancestors could have acquired moral knowledge via reason and enforced rules based on that knowledge, thereby creating selection pressures that drove the evolution of (...) our moral psychology. Given anthropological evidence that early humans designed rules with the conscious aim of preserving individual autonomy and advancing their collective interests, the theory of realist social selection appears to be attractive for moral realists. The goal of evolutionary debunking arguments should be to show not that our moral beliefs are the product of natural selection, but that realist social selection did not occur. (shrink)

This Element analyzes the various forms that design arguments for the existence of God can take, but the main focus is on two such arguments. The first concerns the complex adaptive features that organisms have. Creationists who advance this argument contend that evolution by natural selection cannot be the right explanation. The second design argument - the argument from fine-tuning - begins with the fact that life could not exist in our universe if the constants found in the (...) laws of physics had values that differed more than a little from their actual values. Since probability is the main analytical tool used, the book provides a primer on probability theory. (shrink)

The epistemic status of Natural Selection has seemed intriguing to biologists and philosophers since the very beginning of the theory to our present times. One prominent contemporary example is Elliott Sober, who claims that NS, and some other theories in biology, and maybe in economics, are peculiar in including explanatory models/conditionals that are a priori in a sense in which explanatory models/conditionals in Classical Mechanics and most other standard theories are not. Sober’s argument focuses on some “would promote” (...) sentences that according to him, play a central role in NS explanations and are both causal and a priori. Lange and Rosenberg criticize Sober arguing that, though there may be some unspecific a priori causal claims, there are not a priori causal claims that specify particular causal factors. Although we basically agree with Lange and Rosenberg’s criticism, we think it remains silent about a second important element in Sober’s dialectics, namely his claim that, contrary to what happens in mechanics, in NS explanatory conditionals are a priori, and that this is so in quite specific explanatory models. In this paper we criticize this second element of Sober’s argument by analyzing what we take to be the four possible interpretations of Sober’s claim, and argue that, terminological preferences aside, the possible senses in which explanatory models in NS can qualify, or include elements that can qualify, as a priori, also apply to CM and other standard, highly unified theories. We conclude that this second claim is unsound, or at least that more needs to be said in order to sustain that NS explanatory models are a priori in a sense in which CM models are not. (shrink)

The design argument was rebutted by David Hume. He argued that the world and its contents (such as organisms) were not analogous to human artifacts. Hume further suggested that there were equally plausible alternatives to design to explain the organized complexity of the cosmos, such as random processes in multiple universes, or that matter could have inherent properties to self-organize, absent any external crafting. William Paley, writing after Hume, argued that the functional complexity of living beings, however, defied naturalistic explanations. (...) In effect he dared anyone to come up with an alternative to his inference to design, and hence a designer, outside of nature. Charles Darwin explained the apparent design of functional complexity by his theory of natural selection. Asa Gray, however, in essays as well as in correspondence with Darwin argued that natural selection allowed for a type of ' evolutionary teleology' in which design at most could be considered the result of universal principles. F. E. Hicks updated Hume by specifically objecting to the use of design arguments by Paley. Hicks argued that the apparent design seen in nature reflected order at a deep level in nature. The design argument was briefly revived by Lawrence Henderson early in the twentieth century but he ultimately concluded that design and teleology were not necessarily mutually entailing and he retracted his design argument in favor of one that he termed ' natural teleology'. The current claims of ' intelligent design' have the same logical problems that have beset previous design arguments. If design is divorced from teleology and its discontents put behind us, then there is a possibility that the latter can have a place in the development of theories to explain the phenomena of emergent complexity.

Humans learn in ways that are influenced by others. As a result, cultural items of many types are elaborated over time in ways that build on the achievements of previous generations. Culture therefore shows a pattern of descent with modification reminiscent of Darwinian evolution. This raises the question of whether cultural selection-a mechanism akin to natural selection, albeit working when learned items are passed from demonstrators to observers-can explain how various practices are refined over time. This Element (...) argues that cultural selection is not necessary for the explanation of cultural adaptation; it shows how to build hybrid explanations that draw on aspects of cultural selection and cultural attraction theory; it shows how cultural reproduction makes problems for highly formalised approaches to cultural selection; and it uses a case-study to demonstrate the importance of human agency for cumulative cultural adaptation.
