This paper discusses two perspectives, each of which recognises the importance of environmental resources in enhancing and amplifying our cognitive capacity. One is the Clark–Chalmers model, extended further by Clark and others. The other derives from niche construction models of evolution, models which emphasise the role of active agency in enhancing the adaptive fit between agent and world. In the human case, much niche construction is epistemic: making cognitive tools and assembling other informational resources that support and scaffold intelligent action. (...) I shall argue that extended mind cases are limiting cases of environmental scaffolding, and while the extended mind picture is not false, the niche construction model is a more helpful framework for understanding human action.

Knowledge of the complexity of human communication comes from three main sources – (i) studies of the linguistics and neuropsychology of dysfunction after brain injury; (ii) studies of the development of social communication in infancy, and its dysfunction in developmental psychopathologies; and (iii) the evolutionary history of human communicative interaction. Together, these suggest the need for a broad, integrated theory of communication of which language forms a small but critical component.

Prominent research programs dealing with the nature and mechanisms of interpersonal social coordination have emerged in cognitive science, developmental psychology and evolutionary anthropology. I argue that the mechanistic approach to explanation in contemporary philosophy of science can facilitate interdisciplinary integration and division of labor between these different disciplinary research programs. By distinguishing phenomenal models from mechanistic models and structural decomposition from functional decomposition in the process of mechanism discovery, I argue that behavioral and cognitive scientists can make interlocking contributions to (...) families of mechanism models representing a) what central forms of interpersonal social coordination consist in, b) what types of agents engage in such forms of coordination, c) what types of cognitive mechanisms give rise to such forms of coordination, d) how the operation of such mechanisms is modulated by the natural and social environments that the agents populate. Thus mechanistic philosophy of science can play a heuristic role in guiding the research strategies of scientists in different scientific disciplines in a manner that is complementary to the research strategies of scientists in other disciplines and thereby efficient from the point of view of the division of epistemic labor.

Cognitive scientists and psychometricians are unaccustomed to thinking about culture, often treating their measures – memory, vocabulary, intelligence – as natural kinds. Relying on these measures, behavioral geneticists likewise seem to not wonder about their origin and cultural provenance. I argue that complex human traits – the sort we are most interested in measuring – are cultural products. We can measure them and their heritability, but to conclude that what we have measured is unbound to a time and place is (...) hubris. (shrink)

Substrate independence and mind-body functionalism claim that thinking does not depend on any particular kind of physical implementation. But real-world information processing depends on energy, and energy depends on material substrates. Biological evidence for these claims comes from ecology and neuroscience, while computational evidence comes from neuromorphic computing and deep learning. Attention to energy requirements undermines the use of substrate independence to support claims about the feasibility of artificial intelligence, the moral standing of robots, the possibility that we may be (...) living in a computer simulation, the plausibility of transferring minds into computers, and the autonomy of psychology from neuroscience.

In this paper, in the first place, I aim to enquire into Bernard Stiegler’s critical appropriation of his mentor Jacques Derrida’s notion of différance, emphasizing how Stiegler’s philosophy of technology stems from an original interpretation of the main tenets of deconstruction. From this perspective, I will investigate Stiegler’s definition of technology as tertiary retention, i.e., exosomatized, artificial memory interrelating with biological memory, testing its hermeneutic strengths as well as possible weaknesses. In the second place, I aim to contrast Stiegler’s understanding (...) of technology with the concept of multistability brought forward by postphenomenological philosophies of technology such as those elaborated by Don Ihde and Peter-Paul Verbeek. This investigation will enable me to submit that Stiegler’s approach represents a peculiar and innovative way to conceive of technology. On the one hand, indeed, it does not seem to fall prey to the criticisms raised by postphenomenology against traditional philosophies of technology such as Martin Heidegger’s or Jacques Ellul’s, deemed to be overly deterministic, abstract and pessimistic in their understanding of technology. On the other, it retains important methodological precautions from deconstruction, thereby pointing at some possible blind spots of postphenomenology, especially concerning the vexed question of the empirical-transcendental divide, which Stiegler aims to develop beyond both Derrida’s and postphenomenology’s stances.

The dominant theory of the evolution of moral cognition across a variety of fields is that moral cognition is a biological adaptation to foster social cooperation. This chapter argues, to the contrary, that moral cognition is likely an evolutionary exaptation: a form of cognition where neurobiological capacities selected for in our evolutionary history for a variety of different reasons—many unrelated to social cooperation—were put to a new, prosocial use after the fact through individual rationality, learning, and the development and transmission (...) of social norms. This chapter begins with a brief overview of the emerging behavioral neuroscience of moral cognition. It then outlines a novel theory of moral cognition that I have previously argued explains these findings better than alternatives. Finally, it shows how the evidence for this theory of moral cognition and human evolutionary history together suggest that moral cognition is likely not a biological adaptation. Instead, like reading sheet music or riding a bicycle, moral cognition is something that individuals learn to do—in this case, in response to sociocultural norms created in our ancestral history and passed down through the ages to enable cooperative living.

Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability. During night-time, individuals are generally tired and show decreased self-control and increased impulsive behaviors. The lower visibility during night-time favors the partial concealment of identity and opens more (...) opportunities for disinhibition of self-interested behaviors. Indeed, individuals with an evening-oriented chronotype are more paranoid, risk-taking, extraverted, impulsive, promiscuous, and have higher antisocial personality traits. However, under some circumstances, such as respiratory pandemics, the psychobehavioral traits favored by the nocturnal niche might be counter-productive, increasing contagion rates of a disease that can evade the behavioral immune system because its disease cues are often nonexistent or mild. The eveningness epidemiological liability hypothesis presented here suggests that during the COVID-19 pandemic, the evening-oriented psychobehavioral profile can have collectively harmful consequences: there is a clash of core tendencies between the nocturnal chronotype and the recent viral transmission-mitigating safety guidelines and rules. The pandemic safety protocols disrupt much normal social activity, particularly at night when making new social contacts is desired. The SARS-CoV-2 virus is contagious even in presymptomatic and asymptomatic individuals, which enables it to mostly evade our evolved contagious disease avoidance mechanisms. A growing body of research has indirectly shown that individual traits interfering with social distancing and anti-contagion measures are related to those of the nocturnal chronotype. Indeed, some of the social contexts that have been identified as superspreading events occur at night, such as in restaurants, bars, and nightclubs. Furthermore, nocturnal environmental conditions favor the survival of the SARS-CoV-2 virus much longer than daytime conditions. We compare the eveningness epidemiological liability hypothesis with other factors related to non-compliance with pandemic safety protocols, namely sex, age, and life history. Although there is not yet a direct link between the nocturnal chronotype and non-compliance with pandemic safety protocols, security measures and future empirical research should take this crucial evolutionary mismatch and adaptive metaproblem into account, and focus on how to avoid nocturnal individuals becoming superspreaders, offering secure alternatives for nocturnal social activities.

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)

In this article, I advance a novel hypothesis on the evolution of hominin bipedalism. I begin by arguing extensively for how the transition to bipedalism must have been problematic for hominins during the Neogene. Due to this and the fact that no other primate has made the unusual switch to bipedalism, it seems likely that the selection pressure towards bipedalism was unusually strong. With this in mind, I briefly lay out some of the most promising hypotheses on the evolutionary origin (...) of hominin bipedalism and show how most, if not all, fail in the face of the need for an unusually strong selection pressure. For example, some hypotheses maintain that hominins became bipedal so they could use their hands for carrying infants, food, or other valuable objects. But extant apes are able to carry objects in one of their front limbs (while walking with the other three), and thus it does not seem plausible that our hominin ancestors went through the troublesome transition to bipedalism just so they could carry objects a little more efficiently. After I show that past hypotheses are wanting in the face of this challenge, I argue that there is only one selection pressure powerful enough to instigate a strange and problematic evolutionary adaptation like bipedalism, and that is sexual selection. Specifically, from the fact that bipedal locomotion is an important strategy for intimidating others and ascending the dominance hierarchy in extant apes, I argue that for no particular selective reason bipedal locomotion became a signal for high fitness (much as a large and intricate tail became a signal for high fitness for peahens), and this led to the trait being continuously reinforced in spite of all its deleterious fitness consequences.

The monograph is an English, expanded and revised version of the book Cheshko, V. T., Ivanitskaya, L.V., & Glazko, V.I. (2018). Anthropocene. Philosophy of Biotechnology. Moscow, Course. The manuscript was completed by me on November 15, 2019. It is a study devoted to the development of the concept of a stable evolutionary human strategy as a unique phenomenon of global evolution. The name “An Evolutionary Metaphysics (Cheshko, 2012; Glazko et al., 2016). With equal rights, this study could be entitled “Biotechnology (...) as a result and factor of the evolutionary processˮ. The choice in favor of used “The Evolutionary Metaphysics of Human Enhancement Technologiesˮ was made in accordance with the basic principle of modern post-academician and human-sized science, a classic example of which is biotechnology. The “Metaphysics of Evolution” and “Evolutionary Metaphysics” concepts are used in several ways in modern philosophical discourse. In any case, the values contain a logical or associative reference to the teleological nature of the evolutionary process (Hull, 1967, 1989; Apel, 1995; Faye, 2016; Dupre, 2017; Rose, 2018, etc). In our study, the “evolutionary metaphysics” serves to denote the thesis of the rationalization and technologization of global evolution and anthropogenesis, in particular. At the same time, the postulate of an open future remains relevant in relation to the results of the evolutionary process. The theory of evolution of complex, including the humans system and algorithm for its constructing are а synthesis of evolutionary epistemology, philosophical anthropology and concrete scientific empirical basis in modern science. ln other words, natural philosophy is regaining the status bar element theoretical science in the era of technology-driven evolution. The co-evolutionary concept of 3-modal stable evolutionary strategy of Homo sapiens is developed. The concept based оn the principle of evolutionary complementarity of anthropogenesis: value of evolutionary risk and evolutionary path of human evolution are defined bу descriptive (evolutionary efficiency) and creative-teleological (evolutionary correctness) parameters simultaneously, that cannot bе instrumental reduced to others ones. Resulting volume of both parameters define the vectors of blological, social, cultural and techno-rationalistic human evolution Ьу two gear mechanism genetic and cultural co-evolution and techno-humanitarian balance. The resultant each of them сап estimated Ьу the ratio of socio-psychological predispositions of humanization / dehumanization in mentality. Explanatory model and methodology of evaluation of creatively teleological evolutionary risk component of NBIC technological complex is proposed. Integral part of the model is evolutionary semantics (time-varying semantic code, the compliance of the blological, socio-cultural and techno-rationalist adaptive modules of human stable evolutionary strategy). It is seem necessary to make three clarifications. First, logical construct, “evolutionary metaphysics” contains an internal contradiction, because it unites two alternative explanatory models. “Metaphysics”, as a subject, implies deducibility of the process from the initial general abstract principle, and, consequently, the outcome of the development of the object is uniquely determined by the initial conditions. Predicate, “evolutionary”, means stochastic mechanism of realizing the same principle by memorizing and replicating random choices in all variants of the post-Darwin paradigm. In philosophy, random choice corresponds to the category of “free will” of a reasonable agent. In evolutionary theory, the same phenomenon is reflected in the concept of “covariant replication”. Authors will attempt to synthesize both of these models in a single transdisciplinary theoretical framework. Secondly, the interpretation of the term “evolutionary (adaptive) strategyˮ is different from the classical definition. The difference is that the adaptive strategy in this context is equivalent to the survival, i.e. it includes the adaptation to the environment and the transformation (construction) of the medium in accordance with the objectives of survival. To emphasize this difference authors used verbal construction “adaptiveˮ (rather than “evolutionaryˮ) strategy as more adequate. In all other cases, the two terms may be regarded as synonymous. Thirdly, the initial two essays of this series were published in one book in 2012. Their main goal was the development of the logically consistent methodological concept of stable adaptive (evolutionary) strategy of hominines and the argumentation of its heuristic possibilities as a transdisciplinary scientific paradigm of modern anthropology. The task was to demonstrate the possibilities of the SESH concept in describing and explaining the evolutionary prospects for the interaction of social organization and technology (techno-humanitarian balance) and the associated biological and cultural mechanisms of the genesis of religion (gene-cultural co-evolution). In other words, it was related to the sphere of cultural and philosophical anthropology, i.e. to the axiological component of any theoretical constructions describing the behavior of self-organizing systems with human participation. In contrast, the present work is an attempt to introduce this concept into the sphere of biological anthropology and, consequently, its main goal is to demonstrate the possibility of verification of its main provisions by means of procedures developed by natural science, i.e. refers to the descriptive component of the same theoretical constructions. The result of this in the future should be methods for assessing, calculating and predicting the risk of loss of biological and cultural identity of a person, associated with a permanent and continuously deepening process of development of science and technology.

This essay discusses Cecilia Heyes’ groundbreaking new book Cognitive Gadgets: The Cultural Evolution of Thinking. Heyes’ point of departure is the claim that current theories of cultural evolution fail adequately to make a place for the mind. Heyes articulates a cognitive psychology of cultural evolution by explaining how eponymous “cognitive gadgets,” such as imitation, mindreading and language, mental technologies, are “tuned” and “assembled” through social interaction and cultural learning. After recapitulating her explanations for the cultural and psychological origins of these (...) gadgets, we turn to criticisms. Among those, we find Heyes’ use of evolutionary theory confusing on several points of importance; alternative theories of cultural evolution, especially those of the Tomasello group and of Boyd, Richerson and Henrich, are misrepresented; the book neglects joint attention and other forms of intersubjectivity in its explanation of the origins of cognitive gadgets; and, whereas Heyes accuses other theories of being “mindblind,” we find her theory ironically other-blind and autistic in character.

Parallels in anatomy between humans and domesticated mammals suggest that for the last 300,000 years, Homo sapiens has experienced more intense selection against the propensity for reactive aggression than any other species of Homo. Selection against reactive aggression, a process that can also be called self-domestication, would help explain various physiological, behavioral and cognitive features of humans, including the unique system of egalitarian male hierarchy in mobile hunter-gatherers. Here I review nine leading proposals that could potentially explain why self-domestication occurred (...) in H. sapiens, whether by selecting in favor of cooperation and tolerance or by selecting against aggressiveness. To account for the domestication syndrome, proposals must explain what led to a decline in fitness of highly aggressive males, and why the explanatory factor applies only to H. sapiens rather than to other species of Homo. The proposed explanations invoke genetic group selection; group-structured culture selection (also known as cultural group selection); social selection by female mate choice; social selection by male partner choice; increased self-control; cooperative breeding; high population density; use of lethal weapons; and language-based conspiracy. Most proposals face difficulties in accounting for the origins and/or maintenance of self-domestication. I conclude that the evolution of language-based conspiracy, which is a form of collective intentionality, was the key factor initiating and maintaining self-domestication in H. sapiens, because it is the most convincing mechanism for explaining the selective pressure against individually powerful fighters. Sophisticated language enabled males of low fighting prowess to coordinate in executing physically aggressive and domineering alpha males. This system is known today as a leveling mechanism in small-scale societies. Group-structured culture selection possibly accelerated the process. (shrink)

A fundamental task for any prospective cognitive architecture is information control: routing information to the relevant mechanisms to support a variety of tasks. Jerry Fodor has argued that the Massive Modularity Hypothesis cannot account for flexible information control due to its architectural commitments and its reliance on heuristic information processing. I argue instead that the real trouble lies in its commitment to nativism—recent massive modularity models, despite incorporating mechanisms for learning and self-organization, still cannot learn to control information flexibly enough. (...) After defending this position, I close the paper by discussing wider implications for control and cognitive architecture. (shrink)

Abstract:This article aims to explore the idea that enhancement technologies have been and will continue to be an essential element of what we might call the “human continuum,” and are indeed key to our existence and evolution into persons. Whereas conservative commentators argue that enhancement is likely to cause us to lose our humanity and become something other, it is argued here that the very opposite is true: that enhancement is the core of what and who we are. Using evidence (...) from paleoanthropology to examine the nature of our predecessor species, and their proclivities for tool use, we can see that there is good reason to assume that the development ofHomo sapiensis a direct result of the use of enhancement technologies. A case is also made for broad understandings of the scope of enhancement, based on the significant evolutionary results of acts that are usually dismissed as “unremarkable.” Furthermore, the use of enhancement by modern humans is no different than these prehistoric applications, and is likely to ultimately have similar results. There is no good reason to assume that whatever we may become will not also consider itself human. (shrink)

Empirical evidence is reviewed indicating that the extraordinary aspects of the human mind are due to our species’ ability to go beyond simple “dyadic associations” and to process the relations among three items of information simultaneously. Classic explanations of the “triadic” nature of human skills have been advocated by various scholars in the context of the evolution of human cognition. Here I summarize the core processes as found in (i) the syntax of language, (ii) tool-usage, and (iii) joint attention. I (...) then review the triadic foundations of two perceptual phenomena of great importance in human aesthetics: (iv) harmony perception and (v) pictorial depth perception. In all five subfields of human psychology, most previous work has emphasized the recursive, hierarchical complexity of such “higher cognition,” but a strongly reductionist approach indicates that the core mechanisms are triadic. It is concluded that the cognitive skills traditionally considered to be “uniquely” human require three-way associational processing that most non-Primate animal species find difficult or impossible, but all members of Homo sapiens – regardless of small cultural differences – find easy and inherently intriguing.

According to the working definition of the International Big History Association, ‘Big History seeks to understand the integrated history of the Cosmos, Earth, Life and Humanity, using the best available empirical evidence and scholarly methods’. In recent years Big History has been developing very fast indeed. Big History courses are taught in the schools and universities of several dozen countries. Hundreds of researchers are involved in studying and teaching Big History. The unique approach of Big History, the interdisciplinary genre of (...) history that deals with the grand narrative of 13.8 billion years, has opened up a vast amount of research agendas. Big History brings together constantly updated information from the scientific disciplines and merges it with the contemplative realms of philosophy and the humanities. It also provides a connection between the past, present, and future. Big History is a colossal and extremely heterogeneous field of research encompassing all the forms of existence and all timescales. Unsurprisingly, Big History may be presented in very different aspects and facets. In this volume the Big History is presented and discussed in three different ways. In its first part, Big History is explored in terms of methodology, theories of knowledge, as well as showcasing the personal approach of scholars to Big History. The second section comprises such articles that could clarify Big History's main trends and laws. The third part of this book explores the nature of teaching Big History as well as profiling a number of educational methods. This volume will be useful both for those who study interdisciplinary macroproblems and for specialists working in focused directions, as well as for those who are interested in evolutionary issues of Astrophysics, Geology, Biology, History, Anthropology, Linguistics and other areas of study.

We set out an account of how self-domestication plays a crucial role in the evolution of language. In doing so, we focus on the growing body of work that treats language structure as emerging from the process of cultural transmission. We argue that a full recognition of the importance of cultural transmission fundamentally changes the kind of questions we should be asking regarding the biological basis of language structure. If we think of language structure as reflecting an accumulated set of (...) changes in our genome, then we might ask something like, “What are the genetic bases of language structure and why were they selected?” However, if cultural evolution can account for language structure, then this question no longer applies. Instead, we face the task of accounting for the origin of the traits that enabled that process of structure-creating cultural evolution to get started in the first place. In light of work on cultural evolution, then, the new question for biological evolution becomes, “How did those precursor traits evolve?” We identify two key precursor traits: the transmission of the communication system through learning; and the ability to infer the communicative intent associated with a signal or action. We then describe two comparative case studies—the Bengalese finch and the domestic dog—in which parallel traits can be seen emerging following domestication. Finally, we turn to the role of domestication in human evolution. We argue that the cultural evolution of language structure has its origin in an earlier process of self-domestication. (shrink)

This thesis focuses on the evolution of human social norm psychology. More precisely, I want to show how the emergence of our distinctive capacity to follow social norms and make social normative judgments is connected to the lineage explanation of our capacity to form shared intentions, and how such capacity is related to a diverse cluster of prototypical moral judgments. I argue that in explaining the evolution of this form of normative cognition we also require an understanding of the developmental (...) trajectory of this capacity. For this purpose, the thesis is organized as follow. In the first chapter, I make some methodological remarks and provide the general overview and plan for the dissertation. In the second chapter, I explain what my explanatory target is and why it matters. On the view I am defending, shared intentional psychology gives rise to a special form of psychology that enables us to engage in social normative thinking. These norms are represented as shared intentional states. Moral psychology, in contrast, is more diverse. For moral judgments define a quite heterogeneous class of mental states—although some moral judgments may involve the representation and execution of norms, certainly not all of them do. I show that although much of our distinctive social norm psychology can be explained within the framework of shared intentionality, moral judgments cannot be unified in the same way. In the third chapter, I provide the baseline of social-cognitive capacities that serve as starting point for my lineage explanation. I argue that hominin social cognition was for a very long period of our evolutionary history essentially a matter of low-level cognitive and motivational processes. On this picture, bottom-up affective processes regulated the social lives of early hominins without requiring any special top-down mechanism of normative thinking such as a capacity for understanding and representing social norms. In the fourth chapter, I argue that human-like social norm psychology evolved as a result of the selective pressures that gave rise to shared intentionality, especially the demands that came from collective hunting. Yet collective hunting was not the whole story of the evolution of shared intentionality, for our capacity to form shared intentional mental states emerged from the interplay between the selective pressures that led to cooperative breeding in humans as well as organized, goal-oriented, collective hunting. Thus, I propose an evo-devo account of shared intentionality and its normative dimension since I argue that explaining the evolution of this particular form of normative thinking crucially depends on information about the developmental trajectory of this capacity. Finally, in the fifth chapter, I focus on how social norms are acquired and how the way we learn them gives rise to some prototypical cluster of moral judgments. Thus, this chapter returns to some of themes and arguments of the first chapter by explaining how the distinction between moral judgments and nonmoral judgments can be culturally transmitted.

Today, music is ubiquitous, highly valued in all known cultures, playing many roles in human daily life. The ethnographic study of the music of extant human foragers makes this quite apparent. Moreover, music is ancient. Sophisticated bird-bone and ivory flutes dated from 40 kya reveal an even earlier musical-technological tradition. So is music likely to be an entrenched feature of human social life during the long passage to behavioral modernity—say, by 150 kya—or earlier? In this article I sketch an evolutionary (...) model that focuses on hominin vocal musicality and communication in the Pleistocene, tracking between series of phenotypes and changes in ecological, social, cognitive, and informational contexts. The model links musicality and protomusic to a bigger picture of hominin socio-cognitive evolution, making some connections clearer, motivating further theorizing and the search for new evidence.

According to one currently influential line of thinking, the evolution of ostensive communication was a prerequisite for the evolution of human language. In this article, I distinguish between a strong and a weak version of this view and offer a sustained argument against the former. More specifically, the strong version of this view would have it that ostensive communication was a prerequisite not just for the evolution of fully modern language but for any language-like system of communication. I argue that (...) this version is too strong: I show how some distinctive and important features of language may well have been assembled prior to the evolution of ostensive communication. Put another way, I argue that a protolanguage before ostensive communication scenario is a real possibility. I conclude by briefly arguing that such an evolutionary scenario coheres better with archaeological evidence from the early Pleistocene as well as evidence from developmental psychology pertaining to the nature of our mind reading abilities.

There are good reasons to think that Brahmanism initially belonged to a geographically limited area, with its heartland in the middle and western parts of the Gangetic plain. It was in this region that Brahmanism was at that time the culture of a largely hereditary class of priests, the brahmins, who derived their livelihood and special position in society from their close association with the local rulers. This situation changed. The most plausible hypothesis as to the reasons of this change (...) sees a link with the political unification of northern India, begun by the Nandas and continued by the Mauryas. Both the Nandas and the Mauryas had their home base in the region called Magadha and had no particular interest in brahmins and their sacrificial tradition. As a result Brahmanism as an institution was under threat; it either had to face disappearance, or reinvent itself. It did the latter. Brahmanism underwent a transformation that enabled it to survive and ultimately flourish in changed circumstances. This paper will argue that the Mahābhārata can be looked upon as an element in this Brahminical project. Far from being a mere collection of stories and general good advice, it was an instrument in the hands of a group of people who were determined to change the world in ways that suited them, and who to a considerable extent succeeded in doing so during the centuries that lay ahead.

Adaptation by means of natural selection depends on the ability of populations to maintain variation in heritable traits. According to the Modern Synthesis this variation is sustained by mutations and genetic drift. Epigenetics, evodevo, niche construction and cultural factors have more recently been shown to contribute to heritable variation, however, leading an increasing number of biologists to call for an extended view of speciation and evolution. An additional common feature across the animal kingdom is learning, defined as the ability to (...) change behavior according to novel experiences or skills. Learning constitutes an additional source for phenotypic variation, and change in behavior may induce long lasting shifts in fitness, and hence favor evolutionary novelties. Based on published studies, I demonstrate how learning about food, mate choice and habitats has contributed substantially to speciation in the canonical story of Darwin’s finches on the Galapagos Islands. Learning cannot be reduced to genetics, because it demands decisions, which requires a subject. Evolutionary novelties may hence emerge both from shifts in allelic frequencies and from shifts in learned, subject driven behavior. The existence of two principally different sources of variation also prevents the Modern Synthesis from self-referring explanations. (shrink)

Technologies and artefacts have long played a role in the structure of human memory and our cognitive lives more generally. Recent years have seen an explosion in the production and use of a new regime of information technologies that might have powerful implications for our minds. Electronic-Memory, powerful, portable and wearable digital gadgetry and “the cloud” of ever-present data services allow us to record, store and access an ever-expanding range of information both about and of relevance to our lives. Already, (...) for a decade we have been carrying around expansive gadgetry which allows us to collect, store and use what would have been almost unimaginable amounts of digital information only a short time ago. Now, thanks to the wireless internet adding vast processing and storage potential to the powerful portable devices which many of us carry constantly or wear, this information can be accessed and customised in an ever-greater variety of ways. How should we assess the implications of the new portable and pervasive cognitive technologies on offer? Does E-Memory and the wider panoply of cloud-enabled cognitive technologies really promise, or threaten, a radical change to the human cognitive abilities and perhaps the very nature of our minds? If so, how are we to assess the possibilities and attempt to understand whether they offer a hopeful or dangerous turn in the human condition? This investigation is structured around four related factors of the new technology: Totality, Practical Incorporability, Autonomy and Entanglement. We use these factors to inquire into the implications of this cloud-based memory technology for our minds and our sense of self. (shrink)

Men’s hunting has dominated the discourse on energy capture and flow in the past decade or so. We turn to women’s roles as critical to household formation, pair-bonding, and intergenerational bonds. Their pivotal contributions in food processing and distribution likely promoted kinship, both genetic and affinal, and appear to be the foundation from which households evolved. With conscious recognition of household social units, variable cultural constructions of human kinship systems that were sensitive to environmental and technological conditions could emerge. Kinship (...) dramatically altered the organization of resource access for our species, creating what we term “kinship ecologies.” We present simple mathematical models to show how hunting leads to dependence on women’s contributions, bonds men to women, and bonds generations together. Kinship, as it organized transfers of food and labor energy centered on women, also became integrated with the biological evolution of human reproduction and life history. (shrink)

Controlled fire use by early humans could have facilitated the evolution of human cooperation. Individuals with regular access to the benefits of domestic fire would have been at an advantage over those with limited or no access. However, a campfire would have been relatively costly for an individual to maintain and open to free riders. By cooperating, individuals could have reduced maintenance costs, minimized free riding and lessened the risk of being without fire. Cooperators were more likely to survive and (...) reproduce than uncooperative individuals because the former would have been better able to maximize a fire’s returns and enjoy regular access to its benefits. This is how the emergence of controlled fire use in Pleistocene human populations could have facilitated the evolution of cooperation. (shrink)

It is generally recognized that descriptive and normative individualism are logically independent theses. This paper defends the stronger view that recognition of the falsehood of descriptive individualism is crucial to understanding the evolutionary and developmental basis of normative individualism. The argument given for this is not analytic; rather, it is based on empirical generalizations about the evolution of markets with specialized labor, about the nature of information processing in large markets, and about the socialization of human children.

An anthropologist describes how he found himself at the vortex of a “clash of medical civilizations:” neoliberalism and the international primary health care movement.

The essay is structured on five ethnographic stories, situated on a continuum from “natural” species-level primary care to “unnatural” neoliberal primary care. Food is an element of all tales. (...)

The dominant view in the cognitive science of religion (the ‘Standard Model’) is that religious belief and behaviour are not adaptive traits but rather incidental byproducts of the cognitive architecture of mind. Because evidence for the Standard Model is inconclusive, the case for it depends crucially on its alleged methodological superiority to selectionist alternatives. However, we show that the Standard Model has both methodological and evidential disadvantages when compared with selectionist alternatives. We also consider a pluralistic approach, which holds that (...) religion or various aspects of religion originated as byproducts of evolved cognitive structures but were subsequently co-opted for adaptive purposes. We argue that when properly formulated, the pluralistic approach also has certain advantages over the Standard Model. (shrink)

There is a tendency in both scientific and humanistic disciplines to think of biological evolution in humans as significantly impeded if not completely overwhelmed by the robust cultural and technological capabilities of the species. The aim of this article is to make sense of and evaluate this claim. In Section 2 , I flesh out the argument that humans are ‘insulated’ from ordinary evolutionary mechanisms in terms of our contemporary biological understandings of phenotypic plasticity, niche construction, and cultural transmission. In (...) Section 3 , I consider two obvious objections to the above argument based on the growing literatures related to gene-culture coevolution and recent positive selection on the human genome, as well as a pair of less common objections relating to the connection between plasticity, population size and evolvability. In Section 4 , I argue that both the ‘human evolutionary stasis argument’ and its various detractor theories are premised on a fundamental conceptual flaw: they take evolutionary stasis for granted, since they fail to conceive of stabilizing selection as a type of evolution and drift as a universal tendency that dominates in the absence of selection. Without the continued operation of natural selection, the very properties that are purported to reduce the evolutionary response to selection in humans would themselves drift into non-functionality. I conclude that properly conceived, biological evolution is a permanent and ineradicable fixture of any species, including Homo sapiens. (shrink)

Sacred value attitudes involve a distinctive profile of norm psychology: an absolutist prohibition on transgressing the value, combined with outrage at even hypothetical transgressions. This article considers three mechanisms by which such attitudes may be adaptive, and relates them to central theories regarding the evolution of religion. The first, “deterrence” mechanism functions to dissuade coercive expropriation of valuable resources. This mechanism explains the existence of sacred value attitudes prior to the development of religion and also explains analogues of sacred value (...) in non-human species. The two remaining mechanisms, “assurance” and “coalitional,” are more likely to have been involved in the cultural evolution of specifically religious behavior. In the assurance mechanism, sacred value attitudes increase the cost of ideological commitments, making them more reliable as signals of a cooperative disposition. In the coalitional mechanism, sacred value attitudes make it dangerous for third parties to dissent from a social norm, and thus discourage competitor ideologies. While both these mechanisms are compatible with major accounts of the evolution of religion, different theories suggest a greater or lesser emphasis on one mechanism or the other. (shrink)

The claim is frequently made that, as cities become loaded up with information and communications technology and a resultant profusion of data, so they are becoming sentient. But what might this mean? This paper offers some insights into this claim by, first of all, reworking the notion of the social as a spatial complex of ‘outstincts’. That makes it possible, secondly, to reconsider what a city which is aware of itself might look like, both by examining what kinds of technological (...) practices are becoming commonplace and by considering the particular case of spatial awareness. In turn, this leads to a third rumination on how cities might become aware as different kinds of sprite, channelling outstincts in spatially variable ways. Whatever the case, it is clear that new technical-artistic interventions are required if these sprites are not to become simply servants of the security–entertainment complex. Some of these interventions are examined in the fourth part of the paper. (shrink)

No later than ~500kya the population of Homo sapiens split into three lin¬eages of independently evolving human populations: Sapiens, Neanderthals and Den¬isovans. After several hundred thousands years, they met several times and interbred with low frequency. Evidence of coupling between them is found in fossil records of Neanderthal – Sapiens offspring and Neanderthal – Denisovans offspring. Moreover, the analysis of ancient and present-day population DNA shows that there were several significant gene flows between populations. Many introgressed sequences from Denisovans and (...) Neanderthals were identified in genomes of currently living populations. All these data, according to biological species definition, may in¬dicate that populations of H. sapiens sapiens and two extinct populations H. sapiens neanderthalensis and H. sapiens denisovensis are one species. Ontological transitions from pre-human beings to humans might have happened before the initial splitting of the Homo sapiens population or after the splitting during evolution of H. sapiens sapiens lineage in Africa. If the ensoulment of the first homo occurred in the evolving populations of H. sapiens sapiens, then occasionally mixed couples created relations that functioned as a family, in which children could have matured.

Cognitive archaeologists infer from material remains to the cognitive features of past societies. We characterize cognitive archaeology in terms of trace-based reasoning, which in the case of cognitive archaeology involves inferences drawing upon background theory linking objects from the archaeological record to cognitive features. We analyse such practices, examining work on cognitive evolution, language, and musicality. We argue that the central epistemic challenge for cognitive archaeology is often not a paucity of material remains, but insufficient constraint from cognitive theories. However, (...) we also argue that the success of cognitive archaeology does not necessarily require well-developed cognitive theories: Success might instead lead to them. (shrink)

How did meat emerge to become such an important feature in Western society? In both popular and academic literatures, biophysical and political-economic factors are often cited as the reason for meat’s preeminent status. In this paper, we perform a comprehensive investigation of these claims by reviewing the available evidence on the political-economic and biophysical features of meat over the long arc of Western history. We specifically focus on nine critical epochs: the Paleolithic, early to late Neolithic, antiquity, ancient Israel and (...) early Christian societies, medieval Europe, early modern Europe, colonial America, the American frontier, and the modern industrial era. We find that except under conditions of environmental scarcity, the meaning and value of meat cannot be attributed to intrinsic biophysical value or to the political-economic actors who materially benefit from it. Rather, meat’s status reflects the myriad cultural contexts in which it is socially constructed in people’s everyday lives, particularly with respect to religious, gender, communal, racial, national, and class identity. By deconstructing the normalized/naturalized materialist assumptions circling around meat consumption, this paper clears a space for a more nuanced appreciation of the role that culture has played in the legitimation of meat, and by extension, the possibility of change.

Building on Dor’s theory of language as a social technology for the instruction of imagination, I suggest that autobiographical memory evolved culturally as a response to the problems of false memory and deliberate deceit that were introduced by that technology. I propose that sapiens’ linguistic communication about past and future events initially occurred in small groups, and this helped to correct individual memory defects. However, when human groups grew in size and became more socially differentiated, and movement between groups prevented (...) story-verification, misattributions of events became more common. In such conditions individuals with better autobiographical memory had an advantage because they could evaluate their own contents and sources of information, as well as that of others, more accurately; this not only benefitted them directly, but also improved their reliability as social partners. Autobiographical memory thus evolved in the context of human linguistic communication through selection for communicative reliability. However, the advantages of imagination, which enables forward-planning and decision-Making, meant that memory distortions, although controlled and moderated by autobiographical memory, could not be totally eradicated. This may have driven the evolution of additional forms of memory control involving social and linguistic norms. I interpret the language and the social norms of the Pirahã as the outcome of the cultural-evolutionary control of memory distortions. Some ways of testing aspects of this proposal are outlined.

This article addresses the question of whether early Pleistocene hominins are plausibly viewed as having possessed a protolanguage, that is, a communication system exemplifying some but not all of the distinctive features of fully modern human language. I argue that the answer is “yes,” mounting evidence from the early Pleistocene “lithics niche.” More specifically, I first describe a cognitive platform that I think would have been sufficient, given appropriate socio-ecological conditions, for the creation and retention of a protolanguage. Then, using (...) archaeological evidence pertaining to hominin lithic behavior from the early Pleistocene, I attempt to make plausible the idea that each of these cognitive abilities were in fact in place by this point in hominin evolutionary history and also that the requisite socio-ecological conditions were satisfied.

In this chapter we discuss some of the central ethical issues specific to eating and harvesting fish. We survey recent research on fish intelligence and cognition and discuss possible considerations that are distinctive to questions about the ethics of eating fish as opposed to terrestrial and avian mammals. We conclude that those features that are distinctive to the harvesting and consumption of fish, including means of capture and the central role that fishing plays in many communities, do not suggest that (...) eating fish is less morally problematic than eating terrestrial of avian animals.

In A Million Years of Music, Gary Tomlinson develops an extensive evolutionary narrative that emphasises several important components of human musicality and proposes a theory of the coalescence of these components. In this essay I tie some of Tomlinson’s ideas to five constraints on theories of music’s evolution. This provides the framework for organising my reconstruction of his model. Thereafter I focus on Tomlinson’s description of ‘entraining’ Acheulean toolmakers and offer several criticisms. I close with some tentative proposals for further (...) theorising. (shrink)

Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes. Evolutionary processes are consilient; they affect several different empirical domains, such as patterns of behavior and the proximal drivers of that behavior. In this target article, we sketch the evidence from five domains that bear on (...) the explanatory adequacy of cultural group selection and competing hypotheses to explain human cooperation. Does cultural transmission constitute an inheritance system that can evolve in a Darwinian fashion? Are the norms that underpin institutions among the cultural traits so transmitted? Do we observe sufficient variation at the level of groups of considerable size for group selection to be a plausible process? Do human groups compete, and do success and failure in competition depend upon cultural variation? Do we observe adaptations for cooperation in humans that most plausibly arose by cultural group selection? If the answer to one of these questions is “no,” then we must look to other hypotheses. We present evidence, including quantitative evidence, that the answer to all of the questions is “yes” and argue that we must take the cultural group selection hypothesis seriously. If culturally transmitted systems of rules (institutions) that limit individual deviance organize cooperation in human societies, then it is not clear that any extant alternative to cultural group selection can be a complete explanation.

Although G. A. Cohen's work on Marx was flawed by a lack of gender-awareness, his work on Rawls owes much of its success to feminist inspiration. Cohen appeals effectively to feminism to rebut the basic structure objection to his egalitarian ethos, and could now appeal to feminism in response to Andrew Williams's publicity objection to this ethos. The article argues that Williams's objection is insufficient to rebut Cohen's ethos, inapplicable to variants of this ethos, and in conflict with plausible gender-egalitarian (...) ethoses. The article also advocates an understanding of basic structuralism and publicity consistent with feminism, and argues that Rawlsians need not reject plausible domestic egalitarian ethoses on either publicity or liberty grounds.

Fire is a force that links everyday human activities to some of the most powerful energetic movements of the Earth. Drawing together the energy-centred social theory of Georges Bataille, the fire-centred environmental history of Stephen Pyne, and the work of a number of ‘pyrotechnology’ scholars, the paper proposes that the generalized study of combustion is a key to contextualizing human energetic practices within a broader ‘economy’ of terrestrial and cosmic energy flows. We examine the relatively recent turn towards fossil-fuelled ‘internal (...) combustion’ in the light of a much longer human history of ‘broadcast’ burning of vegetation and of artisanal pyrotechnologies – the use of heat to transform diverse materials. A combustion-centred analysis, it is argued, brings human collective life into closer contact with the geochemical and geologic conditions of earthly existence, while also pointing to the significance of explorative, experimental and even playful dispositions towards energy and matter.

Eating meat appeals, but the cost is measured in millions of slaughtered animals. This has convinced many that vegetarianism is morally superior to a carnivorous diet. Increasingly, those who take pleasure in consuming animals find it a guilty pleasure. Are they correct? That depends on the magnitude of harm done to food animals but also on what sort of a good, if any, meat eating affords people. This essay aims to estimate both variables and concludes that standard arguments for moral (...) vegetarianism are significantly misplaced. That is because the contribution of meat eating to lives of excellence is underestimated and overall harms to animals consequent on practices of meat eating are overestimated. The answer to the question posed in the title is, therefore, "No.". (shrink)

Currently, production and comprehension are regarded as quite distinct in accounts of language processing. In rejecting this dichotomy, we instead assert that producing and understanding are interwoven, and that this interweaving is what enables people to predict themselves and each other. We start by noting that production and comprehension are forms of action and action perception. We then consider the evidence for interweaving in action, action perception, and joint action, and explain such evidence in terms of prediction. Specifically, we assume (...) that actors construct forward models of their actions before they execute those actions, and that perceivers of others' actions covertly imitate those actions, then construct forward models of those actions. We use these accounts of action, action perception, and joint action to develop accounts of production, comprehension, and interactive language. Importantly, they incorporate well-defined levels of linguistic representation. We show how speakers and comprehenders use covert imitation and forward modeling to make predictions at these levels of representation, how they interweave production and comprehension processes, and how they use these predictions to monitor the upcoming utterances. We show how these accounts explain a range of behavioral and neuroscientific data on language processing and discuss some of the implications of our proposal. (shrink)
