Can heritability estimates provide causal information? This paper argues for an affirmative answer: since a non-nil heritability estimate satisfies certain characteristic properties of causation (i.e., association, manipulability, and counterfactual dependence), it increases the probability that the relation between genotypic variance and phenotypic variance is (at least partly) causal. Contrary to earlier proposals in the literature, the argument does not assume the correctness of any particular conception of the nature of causation, rather focusing on properties that are characteristic of (...) causal relationships. The argument is defended against Lewontin's (1974) locality objection and Kaplan and Turkheimer's (2021) recent critique of Genome-Wide Association Studies (GWAS). (shrink)

In this paper, we provide an overview of our ongoing project in the Genetics and Human Agency Initiative sponsored by the John Templeton Foundation. Our project focuses on the ways that lay beliefs about the heritability of virtue influence reasoning about the nature of virtue, parenting behaviors, and the development of virtue in children. First, we provide philosophical perspectives on the nature of virtue and suggest that viewing virtue as a malleable skill may have important advantages. Next, we review (...) theory and research that highlights the ways that lay heritability beliefs potentially undermine conceptualizations of virtue as a malleable skill. Finally, we discuss how lay heritability beliefs might ultimately affect parent–child interactions and child virtue development. The paper thus provides a brief description our project’s theoretical foundation and a general look at the empirical questions it will tackle. (shrink)

Understanding community-level selection using Lewontin’s criteria requires both community-level inheritance and community-level heritability, and in the discipline of community and ecosystem genetics, these are often conflated. While there are existing studies that show the possibility of both, these studies impose community-level inheritance as a product of the experimental design. For this reason, these experiments provide only weak support for the existence of community-level selection in nature. By contrast, treating communities as interactors (in line with Hull’s replicator-interactor framework or Dawkins’s (...) idea of the “extended phenotype”) provides a more plausible and empirically supportable model for the role of ecological communities in the evolutionary process.

Causation has multiple distinct meanings in genetics. One reason for this is meaning slippage between two concepts of the gene: Mendelian and molecular. Another reason is that a variety of genetic methods address different kinds of causal relationships. Some genetic studies address causes of traits in individuals, which can only be assessed when single genes follow predictable inheritance patterns that reliably cause a trait. A second sense concerns the causes of trait differences within a population. Whereas some single genes can (...) be said to cause population-level differences, most often these claims concern the effects of many genes. Polygenic traits can be understood using heritability estimates, which estimate the relative influences of genetic and environmental differences to trait differences within a population. Attempts to understand the molecular mechanisms underlying polygenic traits have been developed, although causal inference based on these results remains controversial. Genetic variation has also recently been leveraged as a randomizing factor to identify environmental causes of trait differences. This technique—Mendelian randomization—offers some solutions to traditional epidemiological challenges, although it is limited to the study of environments with known genetic influences. (shrink)

Is all explanations causal explanation? Puzzles about barometer readings "explain" storms and shadow lengths "explaining" flagpole heights make it attractive to think so. Wesley Salmon (1984) has endorsed this causal thesis. One way to test this thesis is to assess the explanatory import of pseudo-processes. I do so by discussing the concept of heritability, which measures a pseudo-process, and one role it played in the theory of natural selection: explaining response to selection. This will show, not just that (...) class='Hi'>heritability has heuristic or predictive utility, but that it can be explanatory. Possible responses to this case are also discussed. (shrink)

This article contends that the environmental release of genetically engineered (GE) animals with heritable traits that are patented will present a challenge to the efforts of nations and indigenous peoples to engage in self‐determination. The environmental release of such animals has been proposed on the grounds that they could function as public health tools or as solutions to the problem of agricultural insect pests. This article brings into focus two political‐economic‐legal problems that would arise with the environmental release of such (...) organisms. To address those challenges, it is proposed that nations considering the environmental release of GE animals must take into account the underlying circumstances and policy failures that motivate arguments for the use of the modified animals. Moreover, countries must recognize that the UN International Covenant on Civil and Political Rights and the UN International Covenant on Economic, Social and Cultural Rights place on them an obligation to ensure that GE animals with patented heritable traits are not released without the substantive consent of the nations or indigenous peoples that could be affected.

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)

In an era of dramatic technological progress, the consequent economic transformations, and an increasing need for an adaptable workforce, the importance of education has risen to the forefront of the social discourse. The concurrent increase in the awareness of issues pertaining to social justice and the debate over what this justice entails and how it ought to be effected, feed into the education policy more than ever before. From the nexus of the aforementioned considerations, a concern over the so-called education (...) gap has emerged, with worldwide efforts to close it. I analyse the premises behind such efforts and demonstrate that they are founded upon fundamentally flawed ideas. I show that in a society in which education is delivered equitably, education gaps emerge naturally as a consequence of differentiation due to talents, the tendency for matched mate selection, and the heritability of intellectual traits. Hence, I issue a call for a refocusing of efforts from the ill-founded idea of closing the education gap, to the understanding of the magnitude of its unfair contributions, as well as to those social aspects which can modulate it in accordance to what a society deems fair according to its values.

The article proposes to further develop the ideas of the Extended Evolutionary Synthesis by including into evolutionary research an analysis of phenomena that occur above the organismal level. We demonstrate that the current Extended Synthesis is focused more on individual traits (genetically or non-genetically inherited) and less on community system traits (synergetic/organizational traits) that characterize transgenerational biological, ecological, social, and cultural systems. In this regard, we will consider various communities that are made up of interacting populations, and for which the (...) individual members can belong to the same or to different species. Examples of communities include biofilms, ant colonies, symbiotic associations resulting in holobiont formation, and human societies. The proposed model of evolution at the level of communities revises classic theorizing on the major transitions in evolution by analyzing the interplay between community/social traits and individual traits, and how this brings forth ideas of top-down regulations of bottom-up evolutionary processes (collaboration of downward and upward causation). The work demonstrates that such interplay also includes reticulate interactions and reticulate causation. In this regard, we exemplify how community systems provide various non-genetic ‘scaffoldings’, ‘constraints’, and ‘affordances’ for individual and sociocultural evolutionary development. Such research complements prevailing models that focus on the vertical transmission of heritable information, from parent to offspring, with research that instead focusses on horizontal, oblique and even reverse information transmission, going from offspring to parent. We call this reversed information transfer the ‘offspring effect’ to contrast it from the ‘parental effect’. We argue that the proposed approach to inheritance is effective for modelling cumulative and distributed developmental process and for explaining the biological origins and evolution of language.

It is widely assumed that there is value in the biological tie between parent and child. An implication of this is that adoption is often considered a less desirable alternative to procreation. This paper offers a philosophical defence of adoptive parenthood as a valuable and authentic form of parenthood. While previous defences have suggested that society’s valorisation of the biological tie is unjustified, I argue herein that the conception of the biological tie that features in the normative discourse on parenthood (...) is too narrowly genocentric. Against this genocentric conception, recent work in the philosophy of biology has emphasised the roles of joint determination, dynamic construction, and extended inheritance in development, which I suggest can substantiate a more inclusive conception of the biological tie. Accordingly, I propose that adoptive parents form a rich variety of biological ties with their children, some of which are as heritable and formative as genetic relatedness. (shrink)

The model of human intelligence that is most widely adopted derives from psychometrics and behavioral genetics. This standard approach conceives intelligence as a general cognitive ability that is genetically highly heritable and describable using quantitative traits analysis. The paper analyzes intelligence within the debate on natural kinds and contends that the general intelligence conceptualization does not carve psychological nature at its joints. Moreover, I argue that this model assumes an essentialist perspective. As an alternative, I consider an HPC theory of (...) intelligence and evaluate how it deals with essentialism and with intuitions coming from cognitive science. Finally, I highlight some concerns about the HPC model as well, and conclude by suggesting that it is unnecessary to treat intelligence as a kind in any sense. (shrink)

The utilisation of quantum theories within social science and biology is often reasonably met with dubiety. It would be even more controversial should such theories be applied to concepts under the domain of eugenics. Nonetheless, this can open up a fresh and unique understanding of theories that are usually understood by their classical structure. We will provide quantum interpretations of dysgenics and dysgenic traits from different scopes and procedures. The way dysgenic traits are in a flux with the environment that (...) they interact will be analysed as well as how they interact with each other under quantum conditions. We will also take into account of factors such as intelligence, genetic heritability, and other biological and cognitive factors and try to study their frameworks in non-classical ways. Using what we have theorised, we will also attempt to create numerical and empirical analyses of some of the theories that we have proposed. (shrink)

In the wake of the advent of genome editing technology CRISPR-Cas9 (clustered regularly interspaced palindromic repeat (CRISPR)-associated protein 9), there has been a global debate around the implications of manipulating the human genome. While CRISPR-based germline gene editing is new, the debate about the ethics of gene editing is not – for several decades now, scholars have debated the ethics of making heritable changes to the human genome. The arguments that have been raised both for and against the use of (...) genetic technologies in human reproduction reiterate much of the arguments made in the pre-CRISPR debate. As such, it is instructive for South Africa to reflect on these arguments now, in considering our position on the regulation of the use of this novel biotechnology. There are two dominant schools of thought in this area, bioliberalism and bioconservatism. Bioconservatives raise concerns about the risks of genetic manipulation, and argue that it ought to be limited or prohibited to avert these risks to human health and human nature. Bioliberal scholars are more open to the prospect of genetic manipulation, because of its potential utility. In this article, I conclude that in liberal democracies such as our own, bioliberal arguments ought to be seriously considered when formulating policy on human genome editing because of the extent to which they resonate with our Constitutional values and human rights. I further suggest that there is a need for an enquiry into the relevance of African perspectives on the ethical questions that arise concerning germline genome editing. (shrink)

In this paper I address an important question in Aristotle’s biology, What are the causal mechanisms behind the transmission of biological form? Aristotle’s answer to this question, I argue, is found in Generation of Animals Book 4 in connection with his investigation into the phenomenon of inheritance. There we are told that an organism’s reproductive material contains a set of "movements" which are derived from the various "potentials" of its nature (the internal principle of change that initiates and controls development). (...) These movements, I suggest, function as specialized vehicles for communicating the parts of the parent’s heritable form during the act of reproduction. After exploring the details of this mechanism, I then take up Aristotle’s theory of inheritance proper. At the heart of the theory are three general principles (or 'laws') that govern the interactions between the maternal and paternal movements, the outcome of which determines the pattern of inheritance for the offspring. Although this paper is primarily aimed at providing a detailed analysis of Aristotle’s account of inheritance, the results of that analysis have implications for other areas of Aristotle’s biology. One of the most interesting of these is the question of whether Aristotle’s biology is anti-evolutionary (as traditionally assumed) or whether (as I argue) it leaves room for a theory of evolution by natural selection, even if Aristotle himself never took that step.

Objective. We investigated associations between adults’ beliefs about the heritability of virtue and endorsements of the efficacy of specific parenting styles. Design. In Studies 1 (N = 405) and 2 (N = 400), beliefs about both the genetic etiology of virtuous characteristics and parenting were assessed in samples of parents and non-parents. In Study 3 (N = 775), participants were induced to view virtue as determined by genes or as determined by social factors. Heritability beliefs and authoritarian parenting (...) endorsements were subsequently measured. Results. Study 1 and Study 2 converged to reveal that tendencies to view characteristics as determined by genes were positively associated with endorsement of authoritarian parenting styles. This association occurred independent of individual differences in essentialism and rightwing authoritarianism. Study 3 revealed that exposure to genetic accounts of virtue increased beliefs that virtue is caused by genes, which in turn was positively associated with endorsements of authoritarian parenting responses to child problem behavior. Exposure to genetic accounts of virtue increased endorsement of authoritarian parenting among parents, but was unrelated to authoritarian parenting among non-parents. Conclusions. These studies suggest that genetic accounts of virtuous characteristics reliably relate to more positive beliefs about harsh and controlling parenting practices, illuminating an unrecognized cognitive factor associated with authoritarian parenting endorsement.

Some adaptationist explanations are regarded as maximally solid and others fanciful just-so stories. Just-so stories are explanations based on very little evidence. Lack of evidence leads to circular-sounding reasoning: “this trait was shaped by selection in unseen ancestral populations and this selection must have occurred because the trait is present.” Well-supported adaptationist explanations include evidence that is not only abundant but selected from comparative, populational, and optimality perspectives, the three adaptationist subdisciplines. Each subdiscipline obtains its broad relevance in evolutionary biology (...) via assumptions that can only be tested with the methods of the other subdisciplines. However, even in the best-supported explanations, assumptions regarding variation, heritability, and fitness in unseen ancestral populations are always present. These assumptions are accepted given how well they would explain the data if they were true. This means that some degree of “circularity” is present in all evolutionary explanations. Evolutionary explanation corresponds not to a deductive structure, as biologists usually assert, but instead to ones such as abduction or induction. With these structures in mind, we show the way to a healthier view of “circularity” in evolutionary biology, and why integration across the comparative, populational, and optimality approaches is necessary.

Prior research has demonstrated that antisocial behavior, substance-use disorders, and personality dimensions of aggression and impulsivity are indicators of a highly heritable underlying dimension of risk, labeled externalizing. Other work has shown that individual trait constructs within this psychopathology spectrum are associated with reduced self-monitoring, as reflected by amplitude of the error-related negativity (ERN) brain response. In this study of undergraduate subjects, reduced ERN amplitude was associated with higher scores on a self-report measure of the broad externalizing construct that links (...) these various indicators. In addition, the ERN was associated with a response-locked increase in anterior theta (4–7 Hz) oscillation; like the ERN, this theta response to errors was reduced among high-externalizing individuals. These findings suggest that neurobiologically based deficits in endogenous action monitoring may underlie generalized risk for an array of impulse-control problems. (shrink)

Certain traits, such as intelligence and mental deficiency, have been the focus of eugenic research and propaganda. This focus on such eugenic traits builds on three commonsense ideas: (1) People differ with respect to some of their traits, such as eye-colour and height; (2) Many traits run in families, being passed on from parents to their children; (3) Some traits are desirable, while others are undesirable. These three ideas about traits—their variability, heritability, and desirability—fed the much more controversial eugenicist (...) view that some traits make a person of “good stock”, while others reflect the fact that she comes from “inferior stock”. In combination with the power to influence human reproduction, the systematic study of eugenic traits has thus been thought to provide the basis for human improvement across generations. Three sources reveal which traits were considered important to eugenicists, the public, and decision makers: the research publications of eugenicists, discussions of eugenics in public and popular media, and legislation.

A case could be made that the practice of philosophy demands a certain humility, or at least intellectual humility, requiring such traits as inquisitiveness, openness to new ideas, and a shared interest in pursuing truth. In the positive psychology movement, the study of both humility and intellectual humility has been grounded in the methods and approach of personality psychology, specifically the examination of these virtues as traits. Consistent with this approach, the chapter begins with a discussion of the examination of (...) intellectual humility as a “character trait,” comparing intellectual humility to various well-known traits in the personality psychology literature (e.g the “Big 5” and the “Big 2”) as well as other key traits such as the need for cognition and the need for closure. The chapter then turns to the proverbial issue of whether virtues in general, and intellectual humility in particular, are a matter of “nature”- that is, an innate trait determined by heritability, or “nurture” – a trait mostly shaped by situation and environment. While the chapter does not resolve the issue, it provides occasion for an examination of the role of situations in the expression of intellectual humility, and for the interaction of “situation” and “trait.” The chapter concludes with a discussion of how the interaction of trait with situation provides the most robust understanding of the psychology of any character virtue, including humility and intellectual humility.

Reichenbach’s early solution to the scientific problem of how abstract mathematical representations can successfully express real phenomena is rooted in his view of coordination. In this paper, I claim that a Reichenbach-inspired, ‘layered’ view of coordination provides us with an effective tool to systematically analyse some epistemic and conceptual intricacies resulting from a widespread theorising strategy in evolutionary biology, recently discussed by Okasha (2018) as ‘endogenization’. First, I argue that endogenization is a form of extension of natural selection theory that (...) comprises three stages: quasi-axiomatisation, functional extension, and semantic extension. Then, I argue that the functional extension of one core principle of natural selection theory, namely, the principle of heritability, requires the semantic extension of the concept of inheritance. This is because the semantic extension of ‘inheritance’ is necessary to establish a novel form of coordination between the principle of heritability and the extended domain of phenomena that it is supposed to represent. Finally, I suggest that – despite the current lack of consensus on the right semantic extension of ‘inheritance’ – we can fruitfully understand the reconceptualization of ‘inheritance’ provided by niche construction theorists as the result of a novel form of coordination.

La vieille question du statut ontologique du présent refait aujourd’hui surface au travers du débat qui oppose présentisme et éternisme.

Political imputations in science are notoriously a tricky business. I addressed this issue in the context of the nature–nurture debate in the penultimate chapter of my book Making Sense of Heritability (Cambridge U. P. 2005). Although the book mainly dealt with the logic of how one should think about heritability of psychological differences, it also discussed the role of politics in our efforts to understand the dynamics of that controversy. I first argued that if a scholar publicly defends (...) a certain view (say, hereditarianism) in the debate about IQ, race and genetics this fact alone cannot justify attributing a political motivation to that person. But then later I suggested that the pressure of political correctness could explain some peculiarities of the contemporary controversy about the heritability of group differences in IQ. Several reviewers of my book raised a tu quoque objection. Am I not doing here the same thing that I condemn others for? (shrink)

This paper contends that Ananda Abeysekara’s notion of un-inheritance, developed via a Derridean analysis of contemporary Sri Lankan politics and society, can act as a helpful supplement to the concept of justice. What one finds in Abeysekara’s analysis is an interpretation of justice as ultimately aporetic: justice both opens up to the possibility of its ever greater concrete realization and continually defers its completion. This paper begins by examining the aporetic character of justice as articulated by Derrida. It then proceeds (...) to Abeysekara’s account, situated as it is within a largely political consideration of Sri Lanka’s multicultural heritage and the recent conflicts that have arisen there. Abeysekara offers the notion of un-heritance as a way of thinking the possibility of justice precisely when political—and also religious—traditions come to an impasse, thus recognizing the inescapably aporetic structure of justice itself.

In Plato’s Statesman, the Eleatic Stranger applies a specialized method of inquiry—the “method of collection and division”, or “method of division”—in order to discover the nature of statecraft. This paper articulates some consequences of the fact that the method is both a tool for identifying natural kinds—that is, a tool for carving the world by its joints (Phaedrus 265b-d)—and social kinds—that is, the kinds depending on human beings for their existence and explanation. A central goal of the paper is to (...) illuminate the extent to which this use of the method of division allows us to identify Plato as an early historical forerunner of racialism, which is an ideology according to which humanity divides into races differentiated by heritable physiological, cultural, and intellectual traits, as a way of vindicating oppressive and exploitative social, political, and economic systems. -/- I defend an interpretation of the Stranger’s claim, much discussed in the literature, that the division of humankind into Greek and barbarian is unnatural (Politicus 262c-263a). I argue that, in the Stranger’s view, this division reflects subjective illusion and prejudice, rather than the fundamental, and teleological, structure of human social organization, which concerns how human beings rationally cooperate to self-produce as a species. Nonetheless, the Stranger’s alternative theory of the natural structure of human society, I suggest, is proto-racial in another way. Through a brief consideration of the Stranger’s affirmative and complex division of kinds in the city, I argue that he re-introduces naturalistic foundations for unjust human hierarchies through his alternative theory of natural kinds and human social teleology.

This essay is a defense of the social construction of racialism. I follow a standard definition of “racialism” which is the belief that “there are heritable characteristics, possessed by members of our species, that allow us to divide them into a small set of races, in such a way that all the members of these races share certain traits and tendencies with each other that they do not share with other members of any other race”. In particular I want to (...) defend the “radical” social-constructive thesis that holds “the concept of race is exclusively the product of historical and cultural causes. It claims that humans do not tend to classify people into races when groups with different phenotypes meet, save for particular historical circumstances”. The quoted position is the consensus view among historians, sociologists, anthropologists, and other social scientists who study racialism but has recently been criticized by philosophical defenders of cognitive/evolutionary psychological approaches to racialism. Drawing on developmental studies as well as historical and contemporary cross-cultural research, CEP philosophers point to similarities of racialism across time and space. They hold that social constructionist approaches to racialism cannot explain these similarities. I hold that SC approaches do explain these similarities and that such similarities actually pose a significant challenge to the proposed CEP research program on racialism. (shrink)

Debate about legal and policy reform has been haunted by a pernicious confusion about human nature, the idea that it is a set of rigid dispositions, today generally conceived as genetic, that is manifested the same way in all circumstances. Opponents of egalitarian alternatives argue that we cannot depart far from the status quo because human nature stands in the way. Advocates of such reforms too often deny the existence of human nature because, sharing this conception, they think it would (...) prevent changes they deem desirable. Both views rest on deep errors about what it is to have a nature and how genetics works. Human nature, like the nature of anything else, is a set of potentials to behave certain ways in given environments, not a nonsocial genetic something that inevitably produces the same result in any environment. To say that existing inequalities, are due to our genes, inalterable because heritable, ignores that genetic propensities may be differently manifested in different environments. Heritability has meaning only relative to an environment and a population and implies nothing about inevitability. A better sort of inegalitarian argument is that a proposed reform, given our nature, would be too costly even if possible. However, this sort of argument is too rarely supported by evidence and generally ignores the costs of existing inequalities. But egalitarians err in supposing that, if behavior is unconstrained by biology, the status quo is easily alterable. The environment may be extremely hard to change. Legal and policy debate should adopt a correct understanding of human nature as a set of propensities and ask of any proposed reform agreed to be otherwise desirable what and how alterable are its causes, genetic, environmental, or more accurately both.

A common reaction to functional diversity is to group entities into clusters that are functionally similar. I argue here that people are diverse with respect to reasoning-related processes, and that these processes satisfy the basic requirements for evolving entities: they are heritable, mutable, and subject to selective pressures. I propose a metric to quantify functional difference and show how this can be used to place psychological processes into a structure akin to a phylogenetic or evolutionary tree. Three species concepts are (...) repurposed from biology and used to understand relationships in that tree. (shrink)

We often hear how scientists have discovered that a certain human trait – or a trait of another type of organism – is innate, genetic, heritable, inherited, naturally selected etc. All these claims have something in common: they all declare a trait to have significant organism internal (for instance genetic) causes that are present in the organism at its birth. I call claims like these “nativist claims”. Nativist claims are important. They shape our overall understanding of what we are, what (...) we can do and what is good for us. They also impact our practical decision making. For instance, we know that certain types of genes increase the risk of certain diseases, and increasingly this has an effect on healthcare practices. Many people believe that in the matter of children’s education we should consider the fact that many cognitive abilities are highly heritable. Associations between genetics and aggressive behavior have been taken to be alleviating circumstances in criminal sentencing. It is therefore important to correctly understand the content and implications of nativist claims. In this doctoral thesis I analyze, by philosophical means, the content of different kinds of nativist claim. What does it mean that some psychological tendency is innate? What does it mean that intelligence is 50% heritable? How (if at all) do genes come to carry information about the traits of an organism – they are nothing like the information carriers familiar to us, such as newspapers, e-mails, secret codes, and audio files. This thesis emphasizes two things. Firstly, I demonstrate, that in different scientific contexts these words ('innate', 'genetically caused' etc.) can mean very different things. Therefore, the implications of a given nativist claim in one scientific context can be remarkably different from another nativist claim’s implications in some other scientific context. Secondly, I explain how the development of innate, heritable and genetically caused traits can be determined in different and often unexpected ways by our environment and experiences. I demonstrate that the content of a concept that is considered innate by cognitive scientists can be determined by what the organism that possesses the concept has experienced. I also show that even a trait which is 100% heritable can at the same time be a socially constructed trait. (shrink)

Culture or Biology? The question can seem deep and important. Yet, I argue in this chapter, if you are enthralled by questions about our biological differences, then you are probably confused. My goal is to diagnose the confusion. In debates about the role of biology in the social world it is easy to ask the wrong questions, and it is easy to misinterpret the scientific research. We are intuitively attracted to what is called psychological essentialism, and therefore interpret what is (...) biological as what can be traced to “essences”. On this interpretation, it would be deep and important to know what about, say, the differences between the genders is biological: it would correspond to what is essential to being a man or being a woman, and be opposed to what is a mere accidental feature that some women or some men have. Yet, the psychological essentialist understanding of ‘biological differences’ is deeply mistaken about biology. It has the wrong conception of biological kinds, of biological heritability, and of how genes and hormones work. Those who argue for an important role of ‘biology’ in the explanation of human differences often see ‘the science’ on their side. But this is false – on the interpretation of ‘biological differences’ that is most intuitive and that makes the question appear to be most interesting. Defenders of ‘biology’ often have the science against them. What is often called ‘biology’ is a myth: a myth created by an intuitive tendency that grotesquely distorts real biological research.

The place of scientific expertise in democracy has become increasingly disputed, raising question who ought to have a say in decision-making about science and technology, with what authority, and for what reasons. Public engagement has become a common refrain in technoscientific discussions to address tensions in the rightful roles of experts and the public in democratic decision-making. However, precisely what public engagement entails, who it involves, how it is performed, and to what extent it is desirable for democratic societies remain (...) contested matters. Nevertheless, strong commitments to greater public engagement in the governance of science and technology persist. This essay examines expert discussions about heritable human genome editing beginning from the 2015 International Summit on Human Genome Editing through the controversies surrounding of the first CRISPR-edited humans in late 2018 and the subsequent renewed calls for a moratorium on heritable human genome editing. I examine these discussions as example cases in which the right relations among experts, the public, and technoscientific decision-making are actively reconfigured. I argue that rather than expanding the range of included stakeholders, public engagement serves as an enabling handservant of technocracy that reinforces the position of scientific experts in decision-making as both epistemic and normative authorities.

Pour la première fois en langue française, la traduction du Commentaire des huit livres des Physiques d'Aristote de Thomas d'Aquin, offre la quintessence de ce qu'on a appelé l' « aristotélo-thomisme ». Encore méconnue des spécialistes d'Aristote, l’œuvre constitue pourtant le sommet qui domine toute la tradition philosophique antique et médiévale. Traversant les aléas critiques du modernisme et du scientisme des trois derniers siècles, ce commentaire brille d'une actualité renouvelée grâce à l'évolution des sciences physiques et humaines les plus récentes, (...) avec lesquelles il est étonnamment en accord. Les Leçons sur la Nature (autre titre du livre) d'Aristote sont le porche d'entrée pour quiconque veut approfondir la philosophie et en vivre. Le métaphysicien reçoit d'elles le modèle méthodologique et l'assise conceptuelle pour sa contemplation ; le moraliste en hérite les principes d'une éthique rationnelle et sociale ; le théologien y puise les fondements naturels de sa discipline. En détachant le fonds philosophique de son apparat méthodologique, cette traduction met singulièrement l'un et l'autre en relief. La densité de réflexion se voit ainsi libérée des nombreuses coupures techniques, pour permettre une lecture ininterrompue, tandis que l'ordre de progression, dont Thomas d'Aquin avait un tel souci, est exhaussé pour lui-même. L'ensemble se veut donc autant une oeuvre de méditation qu'un instrument de travail. (shrink)
