How is knowledge of geometry developed and acquired? This central question in the philosophy of mathematics has received very different answers. Spelke and colleagues argue for a “core cognitivist”, nativist, view according to which geometric cognition is in an important way shaped by genetically determined abilities for shape recognition and orientation. Against the nativist position, Ferreirós and García-Pérez have argued for a “culturalist” account that takes geometric cognition to be fundamentally a culturally developed phenomenon. In this paper, I argue that (...) when understood as moderate versions supported by the state-of-the-art research, the nativist and culturalist views are in fact possible to reconcile. While Ferreirós and García-Pérez present the work of Spelke and colleagues as implying that geometric cognition is genetically determined, I argue that they fail to appreciate the role that Spelke and colleagues see for cultural factors. On this basis, I provide theoretical and terminological clarifications and show that moderate versions of the nativist and culturalist view are in fact consistent with each other. I then propose a unifying theoretical framework for future study that can integrate the two accounts in ontogeny by moving beyond the crude nature (nativism) vs. nurture (culturalism) dichotomy.

Psychopathy has as its central traits socialization, sensation seeking, and impulsivity. These are combined in a supertrait: Impulsive Unsocialized Sensation Seeking (ImpUSS). Secondary types are defined by combinations of ImpUSS and neuroticism or sociability. All broad personality traits have both genetic and environmental determination, and therefore different etiologies (primary as genetic, secondary as environmental) for primary and secondary sociopathy are unlikely.

Phenotypic plasticity integrates the insights of ecological genetics, developmental biology, and evolutionary theory. Plasticity research asks foundational questions about how living organisms are capable of variation in their genetic makeup and in their responses to environmental factors. For instance, how do novel adaptive phenotypes originate? How do organisms detect and respond to stressful environments? What is the balance between genetic or natural constraints (such as gravity) and natural selection? The author begins by defining phenotypic plasticity and detailing its history, including (...) important experiments and methods of statistical and graphical analysis. He then provides extended examples of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media. (shrink)

This paper argues for a comprehensive conception of empathy as comprising epistemic, affective, and motivational elements and introduces the ancient Stoic theory of attachment as a model for describing the embodied, emotional response to others that we take to be distinctive of empathy. Our argument entails that in order to provide a suitable conceptual framework for the interdisciplinary study of empathy one must extend the scope of recent “simulationalist” and “enactivist” accounts of empathy in two important respects. First, against the (...) enactivist assumption that human mindreading capacities primarily rely on an immediate, quasi-perceptual understanding of other’s intentional states, we draw on Alfred Schutz’ analysis of social understanding to argue that reflective types of understanding play a distinct, but equally fundamental role in empathic engagements. Second, we insist that empathy also involves an affective response toward the other and their situation. We suggest analyzing this response in terms of the Stoic concepts of attachment, concern, and a fundamental type of prosocial motivation, that can best be described as an “extended partiality.” By way of conclusion, we integrate the above concepts into a comprehensive conceptual framework for the study of empathy and briefly relate them to current debates about empathic perception and prosocial motivation. The result, we argue, is an account that stays neutral with regard to the exact nature of the processes involved in producing empathy and can therefore accommodate discussion across theoretical divides—e.g., those between enactivist, simulationalist, and so-called theory-theorist approaches.

Exposome research is put forward as a major tool for solving the nature-versus-nurture debate because the exposome is said to represent “the nature of nurture.” Against this influential idea, we argue that the adoption of the nature-versus-nurture debate into the exposome research program is a mistake that needs to be undone to allow for a proper bioethical assessment of exposome research. We first argue that this adoption is originally based on an equivocation between the (...) traditional nature-versus-nurture debate and a debate about disease prediction/etiology. Second, due to this mistake, exposome research is pushed to adopt a limited conception of agential control that is harmful to one's thinking about the good that exposome research can do for human health and wellbeing. To fully excise the nature-versus-nurture debate from exposome research, we argue that exposome researchers and bioethicists need to think about the exposome afresh from the perspective of actionability. We define the concept of actionability and related concepts and show how these can be used to analyze the ethical aspects of the exposome. In particular, we focus on refuting the popular “gun analogy” in exposome research, returning results to study participants and risk-taking in the context of a well-lived life. (shrink)

A response to Via about the existence (or not) and role of plasticity genes in evolution.

An exploration of the nexus between ecology, evolutionary biology and molecular biology, via the concept of phenotypic plasticity.

Nancy Tuana holds that the nature/nurture dichotomy does not accurately represent the world and hence that a whole series of assumptions about human nature is mistaken. She rejects both biological determinism and alternative interactionist views. I argue that although her arguments and political concerns do rule out any kind of simple biological determinism, they do not show that the alternative interactionist view is untenable: in fact, she uses the distinction in her attempt to demolish it. I argue (...) that the assumption that "nature" implies fixity is the source of difficulties here, not the dichotomy itself. (shrink)

This paper advocates a dispositional account of innate cognitive capacities, which has an illustrious history from Plato to Chomsky. The "triggering model" of innateness, first made explicit by Stich ([1975]), explicates the notion in terms of the relative informational content of the stimulus (input) and the competence (output). The advantage of this model of innateness is that it does not make a problematic reference to normal conditions and avoids relativizing innate traits to specific populations, as biological models of innateness are (...) forced to do. Relativization can be avoided in the case of cognitive capacities precisely because informational content is involved. Even though one cannot measure output relative to input in a precise way, there are indirect and approximate ways of assessing the degree of innateness of a specific cognitive capacity. (shrink)

The concept of reaction norms plays a crucial role in connecting molecular and evolutionary biology.

The pragmatist tradition in philosophy has left a sound legacy in many contemporary research fields. John Dewey’s continuist and emergentist approach to the nature-or-nurture problem in relation to the individual human mind has been regained lately in evolutionist psychology and related disciplines. For Dewey, language plays a fundamental role in creating and maintaining this continuity between the individual mind and the social and physical environment humans inhabit. The present article will focus on a few contemporary lines of research (...) that identify language as the ‘glue’ that bonds each individual to one another and to society, with a decisive impact on the development of one’s own mind.

How micro- and macroevolutionary evolutionary processes produce phenotypic change is without question one of the most intriguing and perplexing issues facing evolutionary biologists. We believe that roadblocks to progress lie A) in the underestimation of the role of the environment, and in particular, that of the interaction of genotypes with environmental factors, and B) in the continuing lack of incorporation of development into the evolutionary synthesis. We propose the integration of genetic, environmental and developmental perspectives on the evolution of the (...) phenotype in the form of the concept of the developmental reaction norm (DRN) The DRN represents the set of multivariate ontogenies that can be produced by a single genotype when it is exposed to environmental variation. It encompasses: 1) the processes that alter the phenotype throughout the ontogenetic trajectory, 2) the recognition that different aspects of the phenotype are (and must be) correlated and 3) the ability of a genotype to produce phenotypes in different environments. This perspective necessitates the explicit study of character expression during development, the evaluation of associations between pairs or groups of characters (e.g., multivariate allometries), and the exploration of reaction norms and phenotypic plasticity. We explicitly extend the concept of the DRN to encompass adjustments made in response to changes in the internal environment as well. Thus, ‘typical’ developmental sequences (e.g., cell fate determination) and plastic responses are simply manifestations of different scales of ‘environmental’ effects along a continuum. We present: (1) a brief conceptual review of three fundamental aspects of the generation and evolution of phenotypes: the changes in the trajectories describing growth and differentiation (ontogeny), the multivariate relationships among characters (allometry), and the effect of the environment (plasticity); (2) a discussion of how these components are merged in the concept of the developmental reaction norm; and (3) a reaction norm perspective of major determinants of phenotypes: epigenesis, selection and constraint.

Developmental plasticity as the nexus between genetics and ecology.

Phenotypic Evolution explicitly recognizes organisms as complex genetic-epigenetic systems developing in response to changing internal and external environments. As a key to a better understanding of how phenotypes evolve, the authors have developed a framework that centers on the concept of the Developmental Reaction Norm. This encompasses their views: (1) that organisms are better considered as integrated units than as disconnected parts (allometry and phenotypic integration); (2) that an understanding of ontogeny is vital for evaluating evolution of adult forms (ontogenetic (...) trajectories, epigenetics, and constraints); and (3) that environmental heterogeneity is ubiquitous and must be acknowledged for its pervasive role in phenotypic expression.

In lieu of an abstract, here is a brief excerpt of the content:Nature and Nurture in French Ethnography and Anthropology, 1859-1914Martin StaumThe adaptability of non-European peoples to "civilization" was a critical issue deriving from the perennial nature-nurture question that haunted debates in the human sciences in late nineteenth-century France.1 The emerging scholarly disciplines of anthropology and ethnography helped provide a scientific veneer that bolstered existing cultural prejudices concerning the innate limitations or retarded development of non-Europeans. Certainly (...) there were many other pragmatic reasons for imperial expansion, and racists did not automatically become imperialists. But if, as Edward Said contended, imperialism "depends upon the idea of having an empire," there is no doubt that many ethnographers and anthropologists helped legitimate the idea.2 Their debates retain a resonance in our twenty-first century postcolonial world struggling with questions of identity, integration, and cultural diversity.Relying on reports from travelers, missionaries, or colonial officials, human scientists from across the political and religious spectrum justified European superiority. Although a few journalists and philosophers outside the scholarly societies represented a minority anti-imperialist counter-current, the remarkable pervasiveness of hierarchical thinking affected both socially radical anthropologists and more conservative ethnographers.3 While ethnographers proclaimed universal fraternity, they conceded that physical differences affected [End Page 475] intellect and character. The later attack on hereditarianism by Durkheimian sociologists and isolated anthropologists with the catalyst of the Dreyfus Affair is all the more striking.4 As George Stocking has argued concerning a British Victorian thinker, the cultural differences between Europeans and non-Europeans became so entangled with biological issues that there was "difficulty conceptualizing them except in terms of 'race.' "5The two most notable anthropological scholarly societies of the late nineteenth century, both founded in 1859, were the Société d'ethnographie orientale et américaine and the Société d'anthropologie de Paris. Historians have justifiably noted their mutual aversion and have contrasted their differences over scientific method, politics, and religion.6 The ethnographers, inspired by a student of Japanese language and Asian religion, Léon de Rosny (1837-1914), were largely linguists and specialists in Asian texts and pre-Columbian codices that represented partly civilized peoples. Rosny invented the term "ambiantisme" for a philosophy that ostensibly privileged the cultural milieu rather than inborn human nature.7 The society membership varied between 115 in 1864 and 470 in 1878, though it declined to 165 by 1903.8 As a group, compared to the anthropologists, they were more politically conservative, more socially elite, and more inclined toward conventional religion, with its belief in the unity of the species. Their "science of destiny" stressed human freedom and unalterably opposed philosophical materialism.9 [End Page 476]The anthropologists, headed by physician and anatomist Paul Broca (1824-80) consisted of a hard core of like-minded medically trained colleagues. The anthropologists' membership peaked around 500 both in 1885 and 1905, though, they, too declined to 165 by 1914.10 Historians have analyzed the nature-nurture issue more subtly for the anthropologists.11 While the Society almost always expressed interest in both physical and cultural spheres, they privileged the study of crania as an index to the intellectual and moral characteristics of "races." The more extreme hereditarians thought that the nature of allegedly inferior "races" precluded perfectibility. Armand de Quatrefages (1810-92), professor of anthropology at the Muséum national d'histoire naturelle and pioneer of the so-called Muséum school, in his later years cast doubt on whether physical indicators actually demonstrated human superiority. However, the Muséum school did not generally renounce racial hierarchy, though they believed that environmental influences formed and continued to shape human varieties.12 In addition, philosophical materialists, militant atheists, and politically radical thinkers dominated the society in the generation after Broca's death. Almost all were neo-Lamarckians who leavened the idea of a fixed human nature with the possibility of adaptation to a milieu and transmissible acquired characteristics.13 The medical physiologist Charles Richet reported that "heredity and milieu are not antagonistic, but synergistic."14 However, many accounts underplay the differential application of neo-Lamarckianism. In this "racial evolutionist paradigm" already noticed by Laurent Mucchielli, even the Muséum school found only civilized people adaptable... (shrink)

The concept of ontogenetic niche is used here to interpret how species-typical behaviors develop through active, context-dependent processes. Ontogenetic niches typically include social stimuli, such as those arising from parents, siblings, and others that provide 'nurturing' in the form of resources, stimulation, and affordances for development. This approach is a useful alternative to wrestling with artificial dichotomies such as nature-nurture.

Research on the origins of human social smiling is presented as a case study of how a species-specific, species-typical behavior may emerge from thousands of momentary events in which a continuously changing biological organism acts to make, respond to, and learn from its experience.

I argue that the human sciences (i.e. humanities, social- and behavioural sciences) should not try to imitate the methodology of the natural sciences. The human sciences study meaningful phenomena whose nature is decisively different from the merely physical phenomena studied by the natural sciences, and whose study therefore require different methods; meaningful phenomena do not obviously obey natural laws while the merely physical necessarily does. This is not to say that the human sciences do not study an objective reality (...) about which we cannot have genuine knowledge. The notion of objective reality is discussed, and it is suggested that social constructions can be understood as objectively real entities. (shrink)

The complex global business environment has created a host of problems for managers, none of which is more difficult to address than bullying in the workplace. The rapid rate of change and the everincreasing complexity of organizational environments of business throughout the world have increased the opportunity for bullying to occur more frequently. This article addresses the foundations of bullying by examining the nature' (i.e., bullying behavior influenced by the innate genetic make-up of an individual) and the nurture' (...) (i.e., individuals learn to be bullies and environments allow the behavior to perpetuate) arguments for the occurrence of bullying behavior. In addition, guidelines are presented for managers in global organizations to use in assessing and monitoring bullying activities in global organizations. (shrink)

The main aim of this article is to examine the contrast between humanism and anti-humanism as two different modern paradigms of considering the individual’s relationship with nature. My thesis is that ecology, as an ideological discourse, reshaped the both the democratic and totalitarian perspectives on humanism and anti-humanism by addressing liberties, self-care, and authenticity in terms of normative laws for environment, health, and the idea of naturalness. Reconsidering Luc Ferry’s analysis from The New Ecological Order: Tree, Animal, Human, I (...) will explain how a social-critical theory of modernity might be conceived in the terms of humanism and anti-humanism, represented by different ecological discourses whose main contribution was to add to the modern social contract the value of non-human beings, including animals, plants, and natural objects as subjects of law (in their most democratic versions) or to discount the value of humans (in their totalitarian structures), viewing racism, for example, as a clinical, biopolitical, and hence “ecological” discourse. I will argue that this condition is a cultural symptom of the anti-natural attitude of the modern individual. (shrink)

The concept of ideology is central to the understanding of the many political, economic, social, and cultural processes that have occurred in the last two centuries. And yet, what is the nature of the different ideologies remains a vague, open, and much disputed question. Many political, sociological, and ideological studies have been devoted to ideology. Very little, on the other hand, has been done from the philosophical field. And this despite the fact that there are undoubtedly many philosophical questions (...) related to ideology and its role in modern industrialized societies. Just a few examples of ideology-related philosophical questions suffice to prove the point: What objects do ideologies deal with? Are the ideologies testable? Are there true ideologies? Do they evolve? How are ideologies related to societies? Is the existence of ideologies inevitable in modern societies? What is the relation of ideology to science? Is science just another kind of ideology? Are we, as human beings, innately predisposed to believe in ideologies? Or, instead, ideologies proliferate through indoctrination and propaganda? Are ideologies necessarily harmful?...and much more. In this article I try to answer some of these questions from a philosophical point of view, taking a materialist approach. I begin by characterizing ideology as a complex, multi-layered concept. Then, I briefly discuss the material systems on which ideological movements operate, that is, societies and concrete human groups. I identify at least 11 different elements that seem to be present in most ideologies, and I compare these characteristics with those of contemporary science and technology. Although some superficial similarities can be identified, there are deep differences that make ideology completely different from science. The similarities, however, are stronger with technology. Ideologies continually evolve with technological advances, social changes, and even with mere fashion. The current fragmentation of ideologies caused by the widespread use of new technologies and social networks has given rise to new phenomena of ideological propagation which, in my opinion, are very dangerous, particularly for open societies. I discuss these processes, within the context of the nature vs nurture debate, along with the question of whether we can get rid of ideologies. (shrink)

A discussion of plasticity genes and the genetic architecture of gene-environment interactions.

Progressive family policy regimes typically aim to promote and protect women’s opportunities to participate in the workforce. These policies offer significant benefits to affluent, two-parent households. A disproportionate number of low-income and impoverished families, however, are headed by single mothers. How responsive are such policies to the objectives of these mothers and the needs of their children? This chapter argues that one-size-fits-all family policy regimes often fail the most vulnerable household and contribute to intergenerational poverty in two ways: by denying (...) at-risk children adequate parenting, and by undermining their mothers’ legitimate interest in nurturing and caring for their own children. The capabilities of these mothers and the well-being of their children are better served by policies which recognise maternal caregiving as a productive and valuable occupation meriting equal respect and social support.
