Il s’agit d’un excellent examen des interactions génétiques / environnement sur le comportement et, en dépit d’être un peu daté, est une lecture facile et utile. Ils commencent par des études jumelles qui montrent l’impact écrasant de la génétique sur le comportement. Ils notent les études de plus en plus connues de Judith Harris qui étendent et résument les faits que l’environnement familial partagé n’a presque aucun effet sur le comportement et que les enfants adoptés grandissent pour être aussi différents (...) de leurs demi-frères et soeurs que les personnes choisies au hasard. Un point fondamental qu’ils (et presque tous ceux qui discutent de la génétique comportementale) ne parviennent pas à noter est que les centaines (des milliers selon votre point de vue) des universels comportementaux humains, y compris toutes les bases de nos personnalités, sont 100% déterminés par nos gènes, sans aucune variation dans les normales. Tout le monde voit un arbre comme un arbre et non une pierre, cherche et mange de la nourriture, se met en colère et jaloux, etc. Donc, ce dont ils parlent surtout ici, c’est de la quantité d’environnement (culture) qui peut influer sur la mesure dans laquelle les divers traits sont montrés, plutôt que leur apparence. Enfin, ils discutent de l’eugénisme de la manière politiquement correcte habituelle, à défaut de noter que nous et tous les organismes sommes les produits de l’eugénisme de la nature et que les tentatives de vaincre la sélection naturelle avec la médecine, l’agriculture, et la civilisation dans son ensemble, sont désastreuses pour toute société qui persiste à le faire. Jusqu’à 50% de toutes les conceptions, soit environ 100 millions par an, se terminent par un avortement spontané précoce, presque tous sans que la mère soit au courant. Cet abattage naturel de gènes défectueux stimule l’évolution, nous maintient relativement génétiquement sains et rend la société possible. Dysgenics est suffisant pour détruire la civilisation, mais la surpopulation sera do ild’abord.

Ce n’est pas un livre parfait, mais il est unique, et si vous écrémez les 400 premières pages ou plus, les 300 dernières (sur quelque 700) sont une assez bonne tentative d’appliquer ce qui est connu sur le comportement aux changements sociaux de la violence et des manières au fil du temps. Le sujet fondamental est le suivant : comment notre génétique contrôle-t-elle et limite-t-elle le changement social ? Étonnamment, il ne parvient pas à décrire la nature de la sélection (...) des parents (fitness inclusif) qui explique une grande partie de la vie sociale animale et humaine. Il n’a pas non plus (comme presque tout le monde) un cadre clair pour décrire la structure logique de la rationalité (LSR—terme préféré de John Searle) que je préfère appeler la psychologie descriptive de la pensée de haut ordre (DPHOT). Il aurait dû dire quelque chose sur les nombreuses autres façons d’abuser et d’exploiter les gens et la planète, car ceux-ci sont maintenant beaucoup plus graves que de rendre d’autres formes de violence presque hors de propos. Étendre le concept de violence pour inclure les-conséquences mondiales à long terme de la réplication des gènes de quelqu’un, et avoir une compréhension de la nature de la façon dont fonctionne l’évolution (c.-à-d., la sélection des parents) fournira une perspective très différente sur l’histoire, les événements actuels, et comment les choses sont susceptibles d’aller dans les quelques centaines d’années. On pourrait commencer par noter que la diminution de la violence physique au cours de l’histoire a été compensée (et rendue possible) par le viol sans pitié de la planète (c’est-à-dire par la destruction par les gens de l’avenir de leur propre descendant). Pinker (comme la plupart des gens la plupart du temps) est souvent distrait par les superficialités de la culture quand c’est la biologie qui compte. Voir mes critiques récentes de Wilson 'The Social Conquest of Earth' et Nowak and Highfield’s 'SuperCooperators' ici et sur le net pour un bref résumé de la vacuité de «véritable altruisme»(sélection de groupe), et le fonctionnement de la sélection des parents et l’inutilité et la superficialité de décrire le comportement en termes culturels. C’est la question classique de la nature/nourrir et la nature l’emporte nourrir - infiniment. Ce qui importe vraiment, c’est la violence faite à la terre par l’augmentation incessante de la population et de la destruction des ressources (en raison de la médecine et de la technologie et de la répression des conflits par la police et l’armée). Environ 200.000 personnes de plus par jour (un autre Las Vegas tous les 10 jours, un autre Los Angeles chaque mois), les 6 tonnes ou plus de la base va dans la mer / personne / année - environ 1% du total du monde disparaissant chaque année, etc. signifie que si un miracle se produit la biosphère et la civilisation va largement s’effondrer au cours des deux prochains siècles, et il y aura la famine, la misère et la violence de tous les types. Les manières, les opinions et les tendances des gens à commettre des actes de violence ne sont d’aucune pertinence à moins qu’ils ne puissent faire quelque chose pour éviter cette catastrophe, et je ne vois pas comment cela va se produire. Il n’y a pas de place pour les arguments, et aucun point non plus (oui je suis un fataliste), donc je vais juste faire quelques commentaires comme s’ils étaient des faits. N’imaginez pas que j’ai un intérêt personnel dans la promotion d’un groupe au détriment des autres. J’ai 78, n’ont pas de descendants et pas de proches parents et ne s’identifient à aucun groupe politique, national ou religieux et considèrent ceux que j’appartiens par défaut aussi répugnant que tout le reste. Les parents sont les pires ennemis de la vie sur Terre et, compte tenu de la vue générale des choses, les femmes sont aussi violentes que les hommes quand on considère le fait que la violence des femmes (comme la plupart de celle faite par les hommes) se fait en grande partie au ralenti, à une distance dans le temps et l’espace et la plupart du temps effectuée par procuration -par leurs descendants et par les hommes. De plus en plus, les femmes portent des enfants, qu’elles aient un compagnon ou non et que l’effet d’empêcher une femme de se reproduire est en moyenne beaucoup plus important que d’arrêter un homme, car ils constituent le goulot d’étranglement reproducteur. On peut considérer que les gens et leur progéniture méritent richement toute la misère vient leur chemin et (à de rares exceptions près) les riches et les célèbres sont les pires délinquants. Meryl Streep ou Bill Gates ou J.K Rowling et chacun de leurs enfants peuvent détruire 50 tonnes de terre d’o re plus chaque année pendant des générations dans l’avenir, tandis qu’un fermier indien et son peut détruire 1 tonne. Si quelqu’un nie que c’est très bien, et à leurs descendants, je dis "Bienvenue à l’enfer sur Terre"(WTHOE). Aujourd’hui, l’accent est toujours mis sur les droits de l’homme, mais il est clair que si la civilisation doit avoir une chance, les responsabilités humaines doivent remplacer les droits de l’homme. Personne n’obtient des droits sans être un citoyen responsable et la première chose que cela signifie est la destruction de l’environnement minimal. La responsabilité la plus fondamentale n’est pas les enfants à moins que votre société vous demande de les produire. Une société ou un monde qui permet aux gens de se reproduire au hasard sera toujours exploité par des gènes égoïstes jusqu’à ce qu’il s’effondre (ou atteint un point où la vie est si horrible qu’il ne vaut pas la peine de vivre). Si la société continue à maintenir les droits de l’homme comme primaires, à leurs descendants, on peut dire avec confiance "WTHOE".

The study of cultural evolution has taken on an increasingly interdisciplinary and diverse approach in explicating phenomena of cultural transmission and adoptions. Inspired by this computational movement, this study uses Bayesian networks analysis, combining both the frequentist and the Hamiltonian Markov chain Monte Carlo (MCMC) approach, to investigate the highly representative elements in the cultural evolution of a Vietnamese city’s architecture in the early 20th century. With a focus on the façade design of 68 old houses in Hanoi’s (...) Old Quarter (based on 78 data lines extracted from 248 photos), the study argues that it is plausible to look at the aesthetics, architecture, and designs of the house façade to find traces of cultural evolution in Vietnam, which went through more than six decades of French colonization and centuries of sociocultural influence from China. The in-depth technical analysis, though refuting the presumed model on the probabilistic dependency among the variables, yields several results, the most notable of which is the strong influence of Buddhism over the decorations of the house façade. Particularly, in the top 5 networks with the best Bayesian Information Criterion (BIC) scores and p<0.05, the variable for decorations (DC) always has a direct probabilistic dependency on the variable B for Buddhism. The paper then checks the robustness of these models using Hamiltonian MCMC method and find the posterior distributions of the models’ coefficients all satisfy the technical requirement. Finally, this study suggests integrating Bayesian statistics in the social sciences in general and for the study of cultural evolution and architectural transformation in particular. (shrink)

We are reliable about logic in the sense that we by-and-large believe logical truths and disbelieve logical falsehoods. Given that logic is an objective subject matter, it is difficult to provide a satisfying explanation of our reliability. This generates a significant epistemological challenge, analogous to the well-known Benacerraf-Field problem for mathematical Platonism. One initially plausible way to answer the challenge is to appeal to evolution by natural selection. The central idea is that being able to correctly deductively reason conferred (...) a heritable survival advantage upon our ancestors. However, there are several arguments that purport to show that evolutionary accounts cannot even in principle explain how it is that we are reliable about logic. In this paper, I address these arguments. I show that there is no general reason to think that evolutionary accounts are incapable of explaining our reliability about logic. (shrink)

For decades Darwinian processes were framed in the form of the Lewontin conditions: reproduction, variation and differential reproductive success were taken to be sufficient and necessary. Since Buss and the work of Maynard Smith and Szathmary biologists were eager to explain the major transitions from individuals to groups forming new individuals subject to Darwinian mechanisms themselves. Explanations that seek to explain the emergence of a new level of selection, however, cannot employ properties that would already have to exist on that (...) level for selection to take place. Recently, Hammerschmidt et al. provided a ‘bottom-up’ experiment corroborating much of the theoretical work Paul Rainey has done since 2003 on how cheats can play an important role in the emergence of new Darwinian individuals on a multicellular level. The aims of this paper are twofold. First, I argue for a conceptual shift in perspective from seeing cheats as a ‘problem’ that needs to be solved for multi-cellularity to evolve to the very ‘key’ for the evolution of multicellularity. Secondly, I illustrate the consequences of this shift for both theoretical and experimental work, arguing for a more prominent role of ecology and the multi-level selection framework within the debate then they currently occupy.

In this article I give a Darwinian account of how sentience, consciousness and language may have evolved. It is argued that sentience and consciousness emerge as brains control purposive actions in new ways. A key feature of this account is that Darwinian theory is interpreted so as to do justice to the purposive character of living things. According to this interpretation, as evolution proceeds, purposive actions play an increasingly important role in the mechanisms of evolution until, with (...) class='Hi'>evolution by cultural means, Darwinian evolution takes on a Lamarckian character. According to this view, as evolution proceeds, the mechanisms of Darwinian evolution themselves evolve. (shrink)

The role of evolutionary theory at the origin of life is an extensively debated topic. The origin and early development of life is usually separated into a prebiotic phase and a protocellular phase, ultimately leading to the Last Universal Common Ancestor. Most likely, the Last Universal Common Ancestor was subject to Darwinian evolution, but the question remains to what extent Darwinian evolution applies to the prebiotic and protocellular phases. In this review, we reflect on the current status of (...) evolutionary theory in origins of life research by bringing together philosophy of science, evolutionary biology, and empirical research in the origins field. We explore the various ways in which evolutionary theory has been extended beyond biology; we look at how these extensions apply to the prebiotic development of (proto)metabolism; and we investigate how the terminology from evolutionary theory is currently being employed in state-of-the-art origins of life research. In doing so, we identify some of the current obstacles to an evolutionary account of the origins of life, as well as open up new avenues of research. (shrink)

Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...) illustrated by showing how life-history theory clarifies the status of so-called diseases of old age.

This paper investigates how reticulate evolution contributes to a better understanding of human sociocultural evolution in general, and community formation in particular. Reticulate evolution is evolution as it occurs by means of symbiosis, symbiogenesis, lateral gene transfer, infective heredity, and hybridization. From these mechanisms and processes, we mainly zoom in on symbiosis and we investigate how it underlies the rise of (1) human, plant, animal, and machine interactions typical of agriculture, animal husbandry, farming, and industrialization; (2) (...) diet-microbiome relationships; and (3) host-virome and other pathogen interactions that underlie human health and disease. We demonstrate that reticulate evolution necessitates an understanding of behavioral and cultural evolution at a community level, where reticulate causal processes underlie the rise of synergistic organizational traits.

Various disciplines, including evolutionary biology, anthropology, archaeology, and psychology, have studied the evolution of rituals. Archaeologists have typically argued that burial practices are one of the most prominent manifestations of ritual practices in the past and have explored various aspects of burial practices, including burial directions. One of the important hypotheses on the cultural evolution of burial practices in Japan is the kitamakura hypothesis, which claims that burial directions (including Kofuns and current burials) were intended to be oriented (...) toward the north after the Kofun period under the influence of Confucianism or Buddhism. This hypothesis would be more plausible if burial directions were not oriented northward before the Kofun period. This research focused on the burial directions in the northern Kyūshū area of the Yayoi period, i.e., the directions of the kamekan jar burials. The results are almost consistent with the hypothesis, although one notable exception is found, and its possible interpretations and implications are discussed. (shrink)

Guided by neuroscience, animal behavior, evolution, philosophy, and psychology, Asma burrows deep into the human psyche to look right at the enigmatic but powerful engine that is our improvisational creativity—the source, he argues, of our remarkable imaginational capacity. How is it, he asks, that a story can evoke a whole world inside of us? How are we able to rehearse a skill, a speech, or even an entire scenario simply by thinking about it? How does creativity go beyond experience (...) and help us make something completely new? And how does our moral imagination help us sculpt a better society? As he shows, we live in a world that is only partly happening in reality. Huge swaths of our cognitive experiences are made up by “what-ifs,” “almosts,” and “maybes,” an imagined terrain that churns out one of the most overlooked but necessary resources for our flourishing: possibilities. Considering everything from how imagination works in our physical bodies to the ways we make images, from the mechanics of language and our ability to tell stories to the creative composition of self-consciousness, Asma expands our personal and day-to-day forms of imagination into a grand scale: as one of the decisive evolutionary forces that has guided human development from the Paleolithic era to today. The result is an inspiring look at the rich relationships among improvisation, imagination, and culture, and a privileged glimpse into the unique nature of our evolved minds. (shrink)

The creation-evolution “controversy” has been with us for more than a century. Here I argue that merely teaching more science will probably not improve the situation; we need to understand the controversy as part of a broader problem with public acceptance of pseudoscience, and respond by teaching how science works as a method. Critical thinking is difficult to teach, but educators can rely on increasing evidence from neurobiology about how the brain learns, or fails to.

The study of phenotypic plasticity has progressed significantly over the past few decades. We have moved from variation for plasticity being considered as a nuisance in evolutionary studies to it being the primary target of investigations that use an array of methods, including quantitative and molecular genetics, as well as of several approaches that model the evolution of plastic responses. Here, I consider some of the major aspects of research on phenotypic plasticity, assessing where progress has been made and (...) where additional effort is required. I suggest that some areas of research, such the study of the quantitative genetic underpinning of plasticity, have been either settled in broad outline or superseded by new approaches and questions. Other issues, such as the costs of plasticity are currently at the forefront of research in this field, and are likely to be areas of major future development. (shrink)

Stephen Jay Gould argued that replaying the ‘tape of life’ would result in radically different evolutionary outcomes. Recently, biologists and philosophers of science have paid increasing attention to the theoretical importance of convergent evolution—the independent origination of similar biological forms and functions—which many interpret as evidence against Gould’s thesis. In this paper, we examine the evidentiary relevance of convergent evolution for the radical contingency debate. We show that under the right conditions, episodes of convergent evolution can constitute (...) valid natural experiments that support inferences regarding the deep counterfactual stability of macroevolutionary outcomes. However, we argue that proponents of convergence have problematically lumped causally heterogeneous phenomena into a single evidentiary basket, in effect treating all convergent events as if they are of equivalent theoretical import. As a result, the ‘critique from convergent evolution’ fails to engage with key claims of the radical contingency thesis. To remedy this, we develop ways to break down the heterogeneous set of convergent events based on the nature of the generalizations they support. Adopting this more nuanced approach to convergent evolution allows us to differentiate iterated evolutionary outcomes that are probably common among alternative evolutionary histories and subject to law-like generalizations, from those that do little to undermine and may even support, the Gouldian view of life.

The natural evolution of consciousness in different animal species mandates that conscious experiences are causally potent in order to confer any advantage in the struggle for survival. Any endeavor to construct a physical theory of consciousness based on emergence within the framework of classical physics, however, leads to causally impotent conscious experiences in direct contradiction to evolutionary theory since epiphenomenal consciousness cannot evolve through natural selection. Here, we review recent theoretical advances in describing sentience and free will as fundamental (...) aspects of reality granted by quantum physical laws. Modern quantum information theory considers quantum states as a physical resource that endows quantum systems with the capacity to perform physical tasks that are classically impossible. Reductive identification of conscious experiences with the quantum information comprised in quantum brain states allows for causally potent consciousness that is capable of performing genuine choices for future courses of physical action. The consequent evolution of brain cortical networks contributes to increased computational power, memory capacity, and cognitive intelligence of the living organisms. (shrink)

Some transhumanists argue that we must engage with theories and facts about our evolutionary past in order to promote future enhancements of the human body. At the same time, they call our attention to the flawed character of evolution and argue that there is a mismatch between adaptation to ancestral environments and contemporary life. One important trait of our evolutionary past which should not be ignored, and yet may hinder the continued perfection of humankind, is the peculiarly human way (...) of bearing and raising children. The suffering associated with childbirth and a long childhood have demanded trade-offs that have enhanced our species, leading to cooperation, creativity, intelligence and resilience. Behaviors such as mother–infant engagement, empathy, storytelling, and ritual have also helped to create what we value most in human beings. Therefore, the moral, cognitive, and emotional enhancements proposed by these transhumanists may be impaired by their partial appropriation of evolution, insofar as the bittersweet experience of parenthood is left aside.

This article introduces a special issue on mechanisms in language evolution research. It describes processes relevant for the emergence of protolanguage and the transition thereof to modern language. Protolanguage is one of the key terms in the field of language evolution, used to designate a hypothesised intermediate stage in the emergence of language present in extinct hominins: qualitatively different from non-human primate communication in possessing some, but not all, of the features that characterise modern language. Much debate in (...) language evolution focuses on the exact delineation of these features, as well as the means whereby the transitions occurred: first from non-human primate communication systems to protolanguage, and then from protolanguage to modern language. In what follows, we first propose a comprehensive typology of protolanguage debates, taking into account the postulated structural organisation of protolanguage, its functions, and its communicative modality. This makes it possible to show how a specific focus on mechanisms and processes deemed relevant for the emergence of these features allows us to assess the explanatory scope of the existing theories of protolanguage.

Despite the widespread use of the notion of moral intuition, its psychological features remain a matter of debate and it is unclear why the capacity to experience moral intuitions evolved in humans. We first survey standard accounts of moral intuition, pointing out their interesting and problematic aspects. Drawing lessons from this analysis, we propose a novel account of moral intuitions which captures their phenomenological, mechanistic, and evolutionary features. Moral intuitions are composed of two elements: an evaluative mental state and a (...) feeling of rightness (FOR). We illustrate the phenomenology of the FOR with examples of non-moral and moral cases, and provide a biological and mechanistic account: the emergence of human reasoning capacities created a need for the co-evolution of a psychological system producing the feeling of rightness (the FORs). This system is triggered when we experience conflicting evaluations. The FORs renders evaluations resulting from rational deliberation less compelling than the evaluations produced by simple evolved systems. It thus facilitates optimal decision-making, preventing excessive interference by rational deliberation. Our account sheds light on why moral intuitions are so frequently experienced and why they are so compelling and resistant to argument. In addition, the account fuels interesting speculations about common metaethical intuitions. (shrink)

This is an epistemologically-driven history of the concept of evolution. Starting from its inception, this work will follow the development of this pregnant concept. However, in contradistinction to previous attempts, the objective will not be the identification of the different meanings it adopted through history, but conversely, it will let the concept to be unfolded, to be explicated and to express its own inner potentialities. The underlying thesis of the present work is, therefore, that the path that leads to (...) the development of the concept of evolution is the path that studies the possibilities of the evolution of concepts, and that the historical reconstruction of its conceptual trajectory will shed light into potential and unexploited possibilities. This methodology will provide useful tools and resources for future developments of the concept. For example, it will define the concept of transmutation as a different conceptual trajectory deviating from the one corresponding to evolution, at the onset of the 19th century. Moreover, epigenesis will not be the opposing concept to evolution, but only to simultaneous and instantaneous generation. It will demonstrate that every important system of epigenesis drew upon some kind of formative power to explain development. More importantly, it will show that the problem of preformation cannot be overlooked, and that some kind of virtual preformation must be considered in order to address the problems of generation and development.

From mitochondria to meerkats, the natural world is full of spectacular examples of social behaviour. In the early 1960s W. D. Hamilton changed the way we think about how such behaviour evolves.

This is a book about the philosophical foundations and future prospects of that program. [Note: only the (...) Introduction is available to download.]. (shrink)

Warum verlief die Evolution bis zum Menschen und ist nicht auf einer früheren Stufe stehen geblie­ben? Verdanken wir unser Dasein einer über Millionen von Jahren abgelaufenen Kette von Zufällen? Kann man das Leben aus toter Materie erklären? Und was ist Leben überhaupt? Die Antworten, die die Naturwissenschaft auf diese grundlegenden Fragen gibt, können ein tieferes Nachdenken nicht befriedigen. In diesem Buch wird gezeigt, dass in der naturalistischen und darwi­nistischen Erklärung des Lebens und seiner Evolution ein entscheidender Faktor übersehen (...) wird, nämlich der erkennende Mensch. Die Fragen nach dem Lebendigen und nach Richtung und Sinn der Evolution können beantwortet werden, wenn das erkennende Bewusstsein nicht als Zuschauer, sondern als integraler Bestandteil der Wirklich­keit mitberücksichtigt wird.

Es zeigt sich, dass die Evolution kein zufälliges Geschehen war, sondern der organische Gesamtprozess der Menschwerdung. (shrink)

The evolutionary process involved the suffering of quadrillions of sentient beings over millions of years. I argue that when we take this into account, then it is likely that when the first humans appeared, the world was already at an enormous axiological deficit, and that even on favorable assumptions about humanity, it is doubtful that we have overturned this deficit or ever will. Even if there’s no such deficit or we can overturn it, it remains the case that everything of (...) value associated with humanity was made possible by our evolutionary history and all that animal suffering. It can seem indecent to regard all that past suffering as having been worth it simply because it was a causal precondition for our existence. But when we consider the realistic alternatives to the way evolution in fact unfolded, there is nevertheless a conditional case for regarding past sentient suffering as a kind of necessary evil.

This chapter introduces the main research schools and paradigms along which the field of evolutionary biology has been developing. Evolutionary thinking was originally founded upon the Neo-Darwinian paradigm that combines the teachings of traditional Darwinism with those of the Modern Synthesis. The Neo-Darwinian paradigm has since further diversified into the Micro-, Meso-, and Macroevolutionary schools, and it has also started to integrate the school of Ecology. Together, these schools establish the paradigm called Ecological Evolutionary Developmental Biology (Eco-Evo-Devo). A final school (...) studies Reticulate Evolution as it occurs by means of symbiosis, symbiogenesis, lateral gene transfer, infective heredity, and hybridization. This chapter reviews the major tenets and points of differentiation that exist between these distinct evolution schools. The chapter ends by looking into how evolution can be defined and how distinct units, levels, and mechanisms underlie theorizing on evolutionary hierarchies and evolutionary causation. The following chapter examines how the different evolution schools are implemented into the symbolic sciences. (shrink)

Phillips et al. make a compelling case for a reversal in the current paradigm in “other minds” research by considering the representation of other people's knowledge more basic than the attribution of belief. Unfortunately, they only discuss primates. In this commentary, I argue that the representation of others' knowledge is an evolutionary ancient trait, first appearing during the Cambrian explosion.

I argue that uniquely human forms of ‘Theory of Mind’ are a product of cultural evolution. Specifically, propositional attitude psychology is a linguistically constructed folk model of the human mind, invented by our ancestors for a range of tasks and refined over successive generations of users. The construction of these folk models gave humans new tools for thinking and reasoning about mental states—and so imbued us with abilities not shared by non-linguistic species. I also argue that uniquely human forms (...) of ToM are not required for language development, such that an account of the cultural origins of ToM does not jeopardise the explanation of language development. Finally, I sketch a historical model of the cultural evolution of mental state talk. (shrink)

Influential thinkers such as Young, Sugden, Binmore, and Skyrms have developed game-theoretic accounts of the emergence, persistence and evolution of social contracts. Social contracts are sets of commonly understood rules that govern cooperative social interaction within societies. These naturalistic accounts provide us with valuable and important insights into the foundations of human societies. However, current naturalistic theories focus mainly on how social contracts solve coordination problems in which the interests of the individual participants are aligned, not competition problems in (...) which individual interests compete with group interests. In response, I set out to build on those theories and provide a comprehensive naturalistic account of the emergence, persistence and evolution of social contracts. My central claim is that social contracts have culturally evolved to solve cooperation problems, which include both coordination and competition problems. I argue that solutions to coordination problems emerge from “within-group” dynamics, while solutions to competition problems result largely from “between-group” dynamics. (shrink)

According to the evolutionary sceptic, the fact that our cognitive faculties evolved radically undermines their reliability. A number of evolutionary epistemologists have sought to refute this kind of scepticism. This paper accepts the success of these attempts, yet argues that refuting the evolutionary sceptic is not enough to put any particular domain of beliefs – notably scientific beliefs, which include belief in Darwinian evolution – on a firm footing. The paper thus sets out to contribute to this positive justificatory (...) project, underdeveloped in the literature. In contrast to a ‘wholesale’ approach, attempting to secure justification for all of our beliefs on the grounds that our belief-forming mechanisms evolved to track truth, we propose a ‘piecemeal’ approach of assessing the reliability of particular belief-forming mechanisms in particular domains. This stands in contrast to the more familiar attempt to transfer warrant obtained for one domain to another by showing how one is somehow an extension of the other. We offer a naturalist reply to the charge of circularity by appealing to reliabilist work on the problem of induction, notably Peter Lipton's distinction between self-certifying and non-self-certifying inductive arguments. We show how, for scientific beliefs, a non-self-certifying argument might be made for the reliability of our cognitive faculties in that domain. We call this strategy Humean Bootstrapping. (shrink)

This book develops a theory of how the imagination functions, and how it evolved. The imagination is characterized as an embodied cognitive system. The system draws upon sensory-motor, visual, and linguistic capacities, but it is a flexible, developmental ability, typified by creative improvisation. The imagination is a voluntary simulation system that draws on perceptual, emotional, and conceptual elements, for the purpose of creating works that adaptively investigate external (environmental) and internal (psychological) resources. Beyond the adaptive useful values of this system, (...) imagination also possesses significant intrinsic value (e.g., in the joy of play, and states of wonder). The book argues that imagination is not a late arrival in the evolution of mind, but one of the earliest human abilities. (shrink)

In this article, I review textual evidence demonstrating that James and Dewey incorporated Kant’s ideas, even while criticizing him. I specifically argue that the pragmatic evolution of the Kantian a priori carried out by James and Dewey is a transition from the mental to the bodily. I further argue that the parallels between pragmatists and Kant, along with the transition from the mental to bodily, relate to scientific contexts in which all developed their outlooks. Though historically grounded, my ultimate (...) goal is to show that pragmatism and by extension Kantianism mesh with and indeed contribute to cutting edge ideas in fields ranging from neuropathology to robotics and AI to cognitive science, whether in the form of Gibsonian theory or enactivism.

This paper offers a more comprehensive and accurate picture of Edmund Husserl’s semiotics. I not only clarify, as many have already done, Husserl’s theory of signs from the 1901 Logical Investigations, but also examine how he transforms that element of his philosophy in the 1913/14 Revisions to the Sixth Logical Investigation. Specifically, the paper examines the evolution of two central tenets of Husserl’s semiotics. I first look at how he modifies his classification of signs. I disclose why he revised (...) his 1901 distinction between indicators and expressions, instead claiming in 1913/14 that the divisions should be drawn between indicators, signals, and categorial signs. Second, I elucidate why Husserl overturned his conclusion from the Investigations, that signs execute their signitive operations in three steps, because he recognizes that categorial signs and their meant object are experienced all at once. By exploring the transformation of these two tenets of Husserl’s semiotics, we will see that he conceived of the First Investigation only as a starting or jumping off point for future analyses of signitive experience, rather than as his final account. This analysis will further reveal novel insights about Husserl’s understanding of intersubjectivity, passivity, and temporality. (shrink)

In this chapter I critically discuss the dismissal of the philosophical significance of facts about human evolution and historical development in the work of W. D Ross. I address Ross’s views about the philosophical significance of the emerging human sciences of his time in two of his main works, namely The Right and the Good and The Foundations of Ethics.

The use of evolutionary game theory to explain the evolution of human norms and the behavior of humans who act according to those norms is widespread. Both the aims and motivation for its use are clearly articulated by Harms and Skyrms (2008) in the following passage: "A good theory of evolution of norms might start by explaining the evolution of altruism in Prisoner’s Dilemma, of Stag Hunting, and of the equal split in the symmetric bargaining game. These (...) are not well-explained by classical game theory based on rational choice. From a technical point of view, they present different theoretical challenges. In the bargaining game, there are an infinite number of equilibria with no principled (rational choice) way to select the cooperative one. In Stag Hunt there are only two, but the non-cooperative one is selected by risk-dominance. In Prisoner’s Dilemma the state of mutual cooperation is not a Nash equilibrium at all, and cooperation flies in the face of the rational-choice principle that one does not choose less rather than more. In contrast to rational choice theory, the most common tool of evolutionary game theory is the replicator dynamics, in which the propagation rate of each strategy is determined by its current payoffs. These dynamics have a rationale in both biological and cultural evolutionary modeling, and sometimes tell us things that rational choice theory does not." We agree with the first sentence in this quotation: a good theory about the behavior under norms ought to explain altruism in the Prisoner’s Dilemma (PD), playing Stag in Stag Hunt (SH), and offering equal splits in the symmetric Nash bargaining game (NB). We also agree with Harms and Skyrms about the difference in technical challenges each of these games poses. Finding a single mechanism, even one as broadly understood as evolution, that could solve these challenges en masse is no doubt a tall order. Nonetheless, in this paper, we present a single, simple, modification to SH, NB, and a general n-player PD that does just that: we introduce deontological autonomy into the models. (shrink)

All disciplines must define their basic units and core processes. In evolutionary biology, the core process is natural selection and the basic unit of selection and adaptation is the individual. To operationalize the theory of natural selection we must count individuals, as they are the bearers of fitness. While canonical individuals have often been taken to be multicellular organisms, the hierarchy of life shows that new kinds of individuals have evolved. A variety of criteria have been used to define biological (...) individuality. Some criteria rely on the presence/absence of a particular property while others advocate an approach that reflects the process of natural selection. The plethora of approaches to classifying individuality has resulted in confusion regarding how to study individuality in a given taxon. (shrink)

Darwinian evolutionary theory has two key terms, variations and biological selection, which finally lead to survival of the fittest variant. With the rise of molecular genetics, variations were explained as results of error replications out of the genetic master templates. For more than half a century, it has been accepted that new genetic information is mostly derived from random error-based events. But the error replication narrative has problems explaining the sudden emergence of new species, new phenotypic traits, and genome innovations (...) as a sudden single event. Meanwhile, it is recognized that errors cannot explain the evolution of genetic information, genetic novelty, and complexity. Now, empirical evidence establishes the crucial role of non-random genetic content editors, such as viruses, diversity generating retroelements, and other RNA networks, to produce new genetic information, complex regulatory control, inheritance vectors, genetic identity, immunity, new sequence space, evolution of complex organisms, and evolutionary transitions.

Drawing on both empirical evidence and evolutionary considerations, Sperber et al. argue that humans have a suite of evolved mechanisms for . On their view, vigilance plays a crucial role in ensuring the reliability and hence the evolutionary stability of communication. This article responds to their argument for vigilance, drawing on additional empirical evidence (from deception detection research) and evolutionary considerations (from animal signalling research) to defend a more optimistic, quasi-Reidian view of communication. On this alternative view, the lion's share (...) of the responsibility for explaining the reliability of testimony falls not to the vigilance of receivers but rather to the honesty of communicators, implying that vigilance does not play a major role in explaining the evolutionary stability of communication.

Die Beziehung der Entwicklung des Lebens im Weltall - von den einfachsten Formen bis zu Leben mit Geist und Bewusstsein – zu der Physik, wie wir sie aus der unbelebten Natur kennen, ist Thema dieses Essays. Ist die Entstehung des Lebens Zufall, ist es Folge einer physikalischen Logik, die noch zu entdecken ist, oder ist „Lebensfreundlichkeit“ ein eigenes Prinzip des Naturgeschehens, das zum Beispiel offene Naturkonstanten der physikalischen Gesetze festlegt, zu denen die geheimnisvollen Grossen Zahlen der Kosmologie gehören – „The (...) Lore of Large Numbers…“? Wissenschaftlich bleibt diese Frage nicht eindeutig zu klären; intuitiv wird das „Prinzip lebensfreundlich“ der menschlichen Evolution wohl am ehesten gerecht. Dabei ist „lebensfreundlich“ in diesem Artikel nicht psychologisch im Sinne menschlicher Beziehungen gemeint, sondern eine Art Kurzbezeichnung für eine Physik, die im Kosmos irgendwann und irgendwo Leben, auch menschliches Leben mit Geist und Bewusstsein ermöglicht. Der Artikel ergänzt auch Texte des Autors über Physik und Bewusstsein, um physikalische und anthropologische Aspekte der Kosmologie (unter philpapers im Volltext). (shrink)

In a series of publications spanning over two decades, William Hasker has argued both that (1) human beings have souls and (2) these souls are not directly created by God but instead are produced by (or “emergent from”) a physical process of some sort or other. By contrast, an alternative view of the human person, endorsed by the contemporary Catholic Church, maintains that (1) human beings have souls but that (2*) each human soul is directly created by God rather than (...) produced by any kind of physical process. Hasker argues that given what we know from evolutionary biology, (2*) is a much less plausible position for believers in souls to take than (2) is. If Hasker is right, then there is a serious tension between the Church’s teaching about the human person and evolutionary biology. In this article, I challenge Hasker’s reasoning. I argue that those who hold the Catholic view that each human soul is directly created by God face no more difficulty reconciling their view with evolutionary biology than those who maintain, as Hasker does, that human souls are instead produced by some kind of physical process.

Aspects of human symbolic evolution are studied by scholars active in a variety of fields and disciplines in the life and the behavioral sciences as well as the scientific-philosophical, sociological, anthropological, and linguistic sciences. These fields and disciplines all take on an evolutionary approach to the study of human symbolism, but scholars disagree in their theoretical and methodological attitudes. Theoretically, symbolism is defined differentially as knowledge, behavior, cognition, culture, language, or social group living. Methodologically, the diverse symbolic evolution (...) sciences establish their teachings upon diverging evolutionary biological schools and paradigms. This chapter reviews past and current research fields in human symbolic evolution for how they differentially implement tenets of the major evolution schools that were discussed in the previous chapter. Traditional evolutionary epistemology and biosemiotics bring in a mesoevolutionary outlook by drawing on early Darwinism and evolutionary developmental biology movements that emphasize the role of the organism in evolution. Communication studies instead originally take on a microevolutionary perspective by investigating how units of information are transmitted across generations through time. Only later do they integrate studies on meaning-making at the organismal level. Sociobiology complements a microevolutionary with a macroevolutionary outlook by implementing population genetic approaches, typical of the Modern Synthesis, into studies on individual and group behavior. The new symbolic evolutionary sciences build upon these traditions and include disciplines such as evolutionary psychology, evolutionary linguistics, evolutionary anthropology, evolutionary archaeology, evolutionary sociology, and evolutionary economics. Originally centered on implementing Darwinian selection theory, these fields are now including ecological and evolutionary developmental biology as well as reticulate evolutionary paradigms. As diverse in outlook and scope as they are, no discipline holds a privileged position over the other and all have made valuable contributions to our understanding of human symbolic evolution.

What makes fast, cumulative cultural evolution work? Where did it come from? Why is it the sole preserve of humans? We set out a self-assembly hypothesis: cultural evolution evolved culturally. We present an evolutionary account that shows this hypothesis to be coherent, plausible, and worthy of further investigation. It has the following steps: (0) in common with other animals, early hominins had significant capacity for social learning; (1) knowledge and skills learned by offspring from their parents began to (...) spread because bearers had more offspring, a process we call CS1 (or Cultural Selection 1); (2) CS1 shaped attentional learning biases; (3) these attentional biases were augmented by explicit learning biases (judgements about what should be copied from whom). Explicit learning biases enabled (4) the high-fidelity, exclusive copying required for fast cultural accumulation of knowledge and skills by a process we call CS2 (or Cultural Selection 2), and (5) the emergence of cognitive processes such as imitation, mindreading and metacognition – ‘cognitive gadgets’ specialised for cultural learning. This self-assembly hypothesis is consistent with archaeological evidence that the stone tools used by early hominins were not dependent on fast, cumulative cultural evolution, and suggests new priorities for research on ‘animal culture’.

Cultural evolution is normally framed in informational terms. However, it is not clear whether this is an adequate way to model cultural evolutionary phenomena and what, precisely, “information” is supposed to mean in this context. Would cultural evolutionary theory benefit from a well-developed theory of cultural information? The prevailing sentiment is that, in contradistinction to biology, informational language should be used nontechnically in this context for descriptive, but not explanatory, purposes. Against this view, this article makes the case for (...) the need to take a proper biology-based “informational turn” in the cultural evolutionary sciences. I argue that the current vague use of informational language misses out on the potential benefits for advancing understanding of phenomena that information-theoretic reasoning has provided in other sciences, especially genetics. In particular, by emphasizing the informational aspects of cultural evolutionary processes, this approach can clarify some conceptual and methodological problems that have plagued cultural evolutionary theory since its inception, including (1) how to determine the channel conditions of cultural information flow, (2) the nature and scope of cultural information, and (3) how to quantify trends of cultural cumulation. More generally, theories of cultural evolution will be incomplete until the mechanisms underlying cultural processes are better understood and integrated into the explanations. This article explores the adequacy of an information-theoretic framework to accomplish these purposes. (shrink)

I outline three conceptions of seeing that a creature might possess: ‘the headlamp conception,’ which involves an understanding of the causal connections between gazing at an object, certain mental states, and behavior; ‘the stage lights conception,’ which involves an understanding of the selective nature of visual attention; and seeing-as. I argue that infants and various nonhumans possess the headlamp conception. There is also evidence that chimpanzees and 3-year-old children have some grasp of seeing-as. However, due to a dearth of studies, (...) there is no evidence that infants or nonhumans possess the stage lights conception of seeing. I outline the kinds of experiments that are needed, and what we stand to learn about the evolution and development of perspective taking. (shrink)

Katarzyna de Lazari-Radek and Peter Singer have recently provided an evolutionary argument for utilitarianism. They argue that most of our deontological beliefs were shaped by evolution, from which they conclude that these beliefs are unjustified. By contrast, they maintain that the utilitarian belief that everyone’s well-being matters equally is immune to such debunking arguments because it wasn’t similarly influenced. However, Guy Kahane remarks that this belief lacks substantial content unless it is paired with an account of well-being, and he (...) adds that utilitarian beliefs about wellbeing—e.g. the belief that pleasure is good and pain is bad—were probably shaped by evolution. Logically, de Lazari-Radek and Singer should therefore reject these beliefs along with the deontological beliefs that evolved. The present paper is a defense of their argument. After considering a number of unsuccessful replies to Kahane’s objection, I put forward a more promising solution: de Lazari-Radek and Singer should combine their objectivist view in metaethics with a subjectivist account of well-being, such as the desire theory. Such a hybrid account would tackle Kahane’s challenge because subjective accounts of value are immune from evolutionary debunking arguments. And it would be compatible with utilitarianism, which doesn’t fit very well with metaethical subjectivism. Before concluding, I deal with two concerns that this solution might raise: I argue that the desire theory is actually subjective enough to escape Kahane’s objection, and I deny that retreating to the combination of ethical objectivism and prudential subjectivism is ad hoc.

This essay moves along broad lines from molecular biology to evolutionary biology and ecology to theology. Its objectives are to: 1) present some recent scientific findings in the emerging field of epigenetics that indicate that it is “the genome in context,” not genes per se, that are important in biological development and evolution; 2) show that this weakens the gene-centric neo-Darwinist explanation of evolution which, in fact, shares a certain preformationist orientation with intelligent design theory; 3) argue that (...) the evidence against a gene-centric view in no way negates Darwin’s central idea of “descent with modification”; 4) argue that an embrace of the evolutionary story, with all of its contingency and apparent lack of directionality, is not only consistent with Christianity, but actually resonates with the notion of the self-emptying love of God in Jesus Christ; and finally 5) suggest that we are called through an ecological imperative to embrace our evolutionary story, to listen to our “genetic coding,” and to reclaim our grounding as a species in the natural world. Corrigendum (published in later issue of journal): There was an error in the paragraph describing the mode of action of the small temporally-expressed RNAs (stRNAs) lin-4 and let-7 from Caenorhabditis elegans. Instead of reading "These two stRNAs act by binding to the tails of their target messenger RNAs (mRNAs); this results in destruction of the target and an overall drop in the level of production of protein from agouti mRNA" [note that agouti mRNA is not a target of these stRNAs], the sentence should have read, "These two stRNAs act by binding to the tails of target messenger RNAs (mRNAs); this leads to inhibition of translation of the mRNAs into protein and a consequent drop in the levels of the corresponding target protein.".

In Darwin’s Dangerous Idea, Daniel Dennett claims that evolution is algorithmic. On Dennett’s analysis, evolutionary processes are trivially algorithmic because he assumes that all natural processes are algorithmic. I will argue that there are more robust ways to understand algorithmic processes that make the claim that evolution is algorithmic empirical and not conceptual. While laws of nature can be seen as compression algorithms of information about the world, it does not follow logically that they are implemented as algorithms (...) by physical processes. For that to be true, the processes have to be part of computational systems. The basic difference between mere simulation and real computing is having proper causal structure. I will show what kind of requirements this poses for natural evolutionary processes if they are to be computational. (shrink)

Heated debates stemming from the confrontation of scientific knowledge with the biblical picture of the creation of man, which had followed the publication of Darwin's theory of evolution, became far less prominent in the second half of the 20th century. This was due to two factors: first, the theory of evolution was partly accepted in theological circles and at the same time biologists showed a growing awareness of the limited epistemological scope of the competence of the natural sciences. (...) This lesson from the history, however, seems to have been forgotten by many who now and again return to controversies which more often than not are caused by ideological quarrels over religion, with true scholarship being too easily lost from sight. The paper reminds some of the history of the controversy in question and suggests that at least some of the current problems regarding evolution˗and˗ creation controversy may have already found their solutions. In part 1, “The Theory of Evolution and the Creation of the Human” it deals with the general issue of human origins. In part 2, “Monogenism and Original Sin” it explores the notion of the ‘first human’ as it is employed in biology and in theology, and shows its completely different meaning in these two realms of knowledge which helps to resolve the recurrent controversy over monogenism.

Most of the free will debate operates under the assumption that classic determinism and indeterminism are the only metaphysical options available. Through an analysis of Dennett’s view of free will as gradually evolving this article attempts to point to emergentist, interactivist and temporal metaphysical options, which have been left largely unexplored by contemporary theorists. Whereas, Dennett himself holds that “the kind of free will worth wanting” is compatible with classic determinism, I propose that his models of determinism fit poorly with (...) his evolutionary theory and naturalist commitments. In particular, his so-called “intuition pumps” seem to rely on the assumption that reality will have a compositional bottom layer where appearance and reality coincide. I argue that instead of positing this and other “unexplained explainers” we should allow for the heretical possibility that there might not be any absolute bottom, smallest substances or universal laws, but relational interactions all the way down. Through the details of Dennett’s own account of the importance of horizontal transmission in evolution and the causal efficacy of epistemically limited but complex layered “selves,” it is argued that our autonomy is linked to the ability to affect reality by controlling appearances.
