According to sources both in print and at a recent meeting, evolutionary theory is currently undergoing change which some would characterize as a New Synthesis, and others as an Extended Synthesis. This article argues that the important changes involve recognizing that there are three means by which evolutionary change can be initiated and three corresponding modes of evolutionary drift. It compares the three and goes on to discuss the scale of innovation and extended or inclusive and Lamarckian inheritance. It concludes (...) from these that “new trends in evolutionary biology” are in part a new, and in part an extended evolutionary synthesis. (shrink)

If all origins of life or of any new grade, level, or major transition as such begin with “competitive development”—with juveniles rather than adults, and multiple individuals rather than a single one—then the evolution of progeneration and of replication always requires an explanation. This article proposes that principles of evolutionary ecology such as density-dependence can be used to explain three kinds of developmental repetitions, viz., sequences of inductive and niche-constructing interactions between the ecological environment and population members, which take place (...) in such a way that the sequence is repeated: individual or somatic repetitions, discussed in Section 1, demographic or progenerative repetitions , discussed in Section 2, and replicative repetitions , discussed in Section 3. This results in a statement of the evolutionary process that includes rather than excludes development and ecology, but one which requires some additions to Van Valen’s aphorism that evolution is the control of development by ecology.

This research was inspired by Werner Callebaut's (1993) classic in which he interviewed major contemporary philosophers of science (specifically of biology) at a time when the interdisciplinary label of "science studies" had hardly been invented. The "real" in his title, Taking the Naturalistic Turn: How Real Philosophy of Science is Done, was a playful reference to debates over realism in Philosophy—the title as a whole drawing attention to his intent to study science studies empirically. That, for Callebaut, was "real" philosophy.In (...) the research reported on here, the works of ten major theorists of the scientific/scholarly process were studied (but not exclusively of biology and chosen from a larger set which ..

Despite a revived interest in explaining the evolution of anisogamy in recent years (i.e. different—micro and macrogametes), there remain more questions than answers. The topic is important because it is thought to be the foundation of the theory of gender differences and relations. Twelve of these questions are briefly reviewed here—(1) the distinction between sex and sexual types; (2) the distinction between mating types and anisogamy; (3) the possible role of ecological as well as social evolution in proto-gender differences and (...) relations; (4) the life history strategies involved; (5) whether the relevant social relationships are based on conflict or cooperation; (6) the origin and properties of meiosis; (7) the conformity of theories with sex allocation theory; (8) the relevance of multiple levels of selection; (9) appropriate modelling strategies; (10) the relationship between the kind of gametes produced and secondary sexual characteristics; (11) the relevance to humans; and (12) how realistic the search for a single explanation is. It is concluded that polarized sexuality may be a form of trade. (shrink)

Social learning in the strict sense is learning by observation or instruction. Learning by observation appears to be an analogue process while learning by instruction is digital. In evolutionary biology this distinction is currently thought to have implications for the extent to which mechanisms can function successfully as an inheritance system in an evolutionary process.

This short paper is about the generalized evolutionary approach to the economics of science. Stephen Toulmin and David Hull are pioneers of the former rather than Karl Popper whose falsification thesis was sociologically naive. Useful directions for the future would go beyond the generalities of variation, transmission and selection towards making more explicit use of Darwin’s “two great principles.” The first is “the unity of types” i.e. common descent by employing phylogenetic methods to answer historical questions. The second is “the (...) conditions of existence” i.e. natural selection by making use of general principles of evolutionary ecology and socioecology to answer questions about why something evolved.

Abstract A lot of science has passed under the bridge since the classic definition of evolution as a change in gene frequencies in a population became common. Much knowledge has accumulated since then about evolution, heredity, ecology, development, phenotypic plasticity, niche construction and genetic drift. Building on Van Valen’s description of evolution as “the control of development by ecology,” it is suggested that the classic definition be replaced by a updated ‘eco‐evo-evo’ definition of evolution by natural selection which acknowledges this (...) accumulation.

This article utilizes three premises. There are commonly ecologically oriented, naturally selected specialized differences in frequency and/or quality as well as sexually selected differences between the sexes. Sex in the sense of coming together and going apart or going apart and coming together is trade in these naturally selected differences, i.e., there is a mating market in sexual species. While such trade is beneficial to the population as a whole, sexual competition and selection is conflict over the profits of that (...) trade and can be detrimental to the population as a whole. These premises yield a naturally selected sex allocation theory of the possible directions and forms of sexual selection, i.e., one that includes costs as well as frequencies. This can explain conventional sex roles, the sex-role reversed, inter- as well as intrasexual selection, and passive as well as active choice. Any of these alternatives may be over mates, over gametes, or both. A hypothetical example based on density dependence relative to resources is provided, one that suggests that centrioles may be a cytoplasmic resource in males in multicellular animals, and which are the target of active choice and the mechanism of manipulation in passive female choice. As a whole, the approach yields a truly general theory of sexual selection, provides an alternative to the mechanism for Fisher’s principle, and gives a theoretical explanation for Mayr’s biological species definition.

On September 30th I attended a talk by Ian Hacking, the renowned philosopher of science. The topic, “The Tree of Knowledge,” was irresistible for someone like myself whose main interest is in sociocultural evolution. I was rewarded with a dazzling display of erudition about stylized trees drawn through history and across civilizations. Hacking generously credited the many experts he had consulted to amass this treasure. This was consistent with his preference for “collaborating disciplines” over interdisciplinarity.

Four theoretical monographs, written by biologists in the wake of the sociobiology debate, and which treat, or purport to treat, the topic of sociocultural evolution are examined in this paper. On the biosocial spectrum they range from Trivers' pure sociobiology, to Lumsden and Wilson's sociobiology "in drag," to Boyd and Richerson's genuinely dual approach, to Cavalli-Sforza and Feldman's purely cultural transmission and evolution. The latter is likely to prove of greatest interest to social scientists and represents a major advance in (...) theorizing mathematically about social change. While the most comprehensive, Boyd and Richerson's "dual inheritance" model ultimately places more emphasis on the biological evolution of the capacity for culture than on genuine gene/culture coevolution even though it is conceivable that cultural transmission and evolution could be providing the selective force responsible for some fundamental biological phenomena such as sexual reproduction in long-lived vertebrates for example. The relationship between contemporary evolutionary and non-evolutionary theories of social change is not dealt with here but the former are very relevant to the latter because evolutionists believe they have available sophisticated solutions to problems which continue to plague other theoretical traditions.

This note provides a definition of evolution by natural selection that is compatible with the extended evolutionary synthesis.

Many analogies exist between the process of evolution by natural selection and of learning by reinforcement and punishment. A full extension of the evolutionary analogy to learning to include analogues of the fitness, genotype, development, environmental influences, and phenotype concepts makes possible a single theory of the learning process able to encompass all of the elementary procedures known to yield learning.

A lesson in evolutionary theory can be drawn from the work of Rick Charnov, who transformed Fisher’s sex ratio theory into sex allocation theory, but unfortunately, the lesson has not spread far enough. The lesson is that costs as well as frequencies need to be included. That is so whether we are talking about evolutionary ecology (e.g., density dependence), social evolution (e.g., sexual selection), origins, an extended evolutionary synthesis, multilevel selection, or whatever. The two dimensions can be expressed in a (...) variety of ways—investing as well as spending, quality as well as quantity, costs as well as frequencies, and somatic as well as reproductive functions, for example. Both are needed everywhere in evolutionary theory. (shrink)

Evolutionary socioecological theory and research proposing linking parasites with human social organization is uncommon and therefore welcome. However, more generally, condition-dependent adaptive phenotypic plasticity requires environmental uncertainty on a small scale, accompanied by reliable cues. In addition, genes in parasites may select among biologically adaptive cultural alternatives directly without necessarily going through human genetic predispositions, resulting in inter-specific gene-culture coevolution.

The most general theory of life history evolution, that of r versus K selection, implies that innovation in the form of plasticity is more likely to be adaptive under poor rather than good resource conditions, the opposite of how Baumard has it. However, this does focus on benefits rather than costs, and including both allows for greater diversity of outcomes.

We present a full completeness theorem for the multiplicative fragment of a variant of noncommutative linear logic, Yetter's cyclic linear logic (CyLL). The semantics is obtained by interpreting proofs as dinatural transformations on a category of topological vector spaces, these transformations being equivariant under certain actions of a noncocommutative Hopf algebra called the shuffie algebra. Multiplicative sequents are assigned a vector space of such dinaturals, and we show that this space has as a basis the denotations of cut-free proofs in (...) CyLL + MIX. This can be viewed as a fully faithful representation of a free *-autonomous category, canonically enriched over vector spaces. This paper is a natural extension of the authors' previous work, "Linear Lauchli Semantics", where a similar theorem is obtained for the commutative logic MLL + MIX. In that paper, we interpret proofs as dinaturals which are invariant under certain actions of the additive group of integers. Here we also present a simplification of that work by showing that the invariance criterion is actually a consequence of dinaturality. The passage from groups to Hopf algebras in this paper corresponds to the passage from commutative to noncommutative logic. However, in our noncommutative setting, one must still keep the invariance condition on dinaturals. (shrink)

Natural kinds is a widely used and pivotal concept in philosophy – the idea being that the classifications and taxonomies employed by science correspond to the real kinds in nature. Natural kinds are often opposed to the idea of kinds in the human and social sciences, which are typically seen as social constructions, characterised by changing norms and resisting scientific reduction. Yet human beings are also a subject of scientific study.Does this mean humans fall into corresponding kinds of their own? (...) In The Epistemology and Morality of Human Kinds Marion Godman defends the idea of human kinds. She first examines the scientific use and nature of human kinds, considering the arguments of key philosophers whose work bears upon human kinds, such as Ian Hacking, John Searle, Richard Boyd and Ruth Millikan. Using the examples of gender, ethnic minorities and Buddhism she then argues that human kinds are a result of ongoing historical reproduction, chiefly due to pre-existing cultural models and social learning. Her novel argument shifts the focus away from the reductionism characteristic of research about human kinds. Instead, she argues that they are “multiply projectable” and deserving of scientific study not in spite of, but because of their role in explaining our identity, injustice and the emergence of group rights.

This paper sheds light on the role of digital platform labour in the development of today’s artificial intelligence, predicated on data-intensive machine learning algorithms. Focus is on the specific ways in which outsourcing of data tasks to myriad ‘micro-workers’, recruited and managed through specialized platforms, powers virtual assistants, self-driving vehicles and connected objects. Using qualitative data from multiple sources, we show that micro-work performs a variety of functions, between three poles that we label, respectively, ‘artificial intelligence preparation’, ‘artificial intelligence verification’ (...) and ‘artificial intelligence impersonation’. Because of the wide scope of application of micro-work, it is a structural component of contemporary artificial intelligence production processes – not an ephemeral form of support that may vanish once the technology reaches maturity stage. Through the lens of micro-work, we prefigure the policy implications of a future in which data technologies do not replace human workforce but imply its marginalization and precariousness. (shrink)

We introduce a linear analogue of Läuchli's semantics for intuitionistic logic. In fact, our result is a strengthening of Läuchli's work to the level of proofs, rather than provability. This is obtained by considering continuous actions of the additive group of integers on a category of topological vector spaces. The semantics, based on functorial polymorphism, consists of dinatural transformations which are equivariant with respect to all such actions. Such dinatural transformations are called uniform. To any sequent in Multiplicative Linear Logic (...) , we associate a vector space of“diadditive” uniform transformations. We then show that this space is generated by denotations of cut-free proofs of the sequent in the theory MLL + MIX. Thus we obtain a full completeness theorem in the sense of Abramsky and Jagadeesan, although our result differs from theirs in the use of dinatural transformations.As corollaries, we show that these dinatural transformations compose, and obtain a conservativity result: diadditive dinatural transformations which are uniform with respect to actions of the additive group of integers are also uniform with respect to the actions of arbitrary cocommutative Hopf algebras. Finally, we discuss several possible extensions of this work to noncommutative logic.It is well known that the intuitionistic version of Läuchli's semantics is a special case of the theory of logical relations, due to Plotkin and Statman. Thus, our work can also be viewed as a first step towards developing a theory of logical relations for linear logic and concurrency. (shrink)

We prove a full completeness theorem for multiplicative–additive linear logic using a double gluing construction applied to Ehrhard’s *-autonomous category of hypercoherences. This is the first non-game-theoretic full completeness theorem for this fragment. Our main result is that every dinatural transformation between definable functors arises from the denotation of a cut-free proof. Our proof consists of three steps. We show:• Dinatural transformations on this category satisfy Joyal’s softness property for products and coproducts.• Softness, together with multiplicative full completeness, guarantees that (...) every dinatural transformation corresponds to a Girard proof-structure.• The proof-structure associated with any dinatural transformation is a proof-net, hence a denotation of a proof. This last step involves a detailed study of cycles in additive proof-structures.The second step is a completely general result, while the third step relies on the concrete structure of a double gluing construction over hypercoherences.

What makes science trustworthy to the public? This chapter examines one proposed answer: the trustworthiness of science is based at least in part on its independence from the idiosyncratic values, interests, and ideas of individual scientists. That is, science is trustworthy to the extent that following the scientific process would result in the same conclusions, regardless of the particular scientists involved. We analyze this "idiosyncrasy-free ideal" for science by looking at philosophical debates about inductive risk, focusing on two recent proposals (...) which offer different methods of avoiding idiosyncrasy: the high epistemic standards proposal and the democratic values proposal.

Is there anything that members of each binary category of gender have in common? Even many non-essentialists find the lack of unity within a gender worrying as it undermines the basis for a common political agenda for women. One promising proposal for achieving unity is by means of a shared historical lineage of cultural reproduction with past binary models of gender. I demonstrate how such an account is likely to take on board different binary and also non-binary systems of gender. (...) This implies that all individuals construed as members of the category, “women” are in fact not members of the same historical kind after all! I then consider different possible means of modifying the account but conclude negatively: the problem runs deeper than has been appreciated thus far. (shrink)

Upon what kind of moral order does capitalism rest? Conversely, does the market give rise to a distinctive set of beliefs, habits, and social bonds? These questions are certainly as old as social science itself. In this review, we evaluate how today's scholarship approaches the relationship between markets and the moral order. We begin with Hirschman's characterization of the three rival views of the market as civilizing, destructive, or feeble in its effects on society. We review recent work at the (...) intersection of sociology, economics, and political economy and show that these views persist both as theories of market society and moral arguments about it. We then argue that a fourth view, which we call moralized markets, has become increasingly prominent in economic sociology. This line of research sees markets as cultural phenomena and moral projects in their own right, and seeks to study the mechanisms and techniques by which such projects are realized in practice.

Joint action is a growing field of research, spanning across the cognitive, behavioral, and brain sciences as well as receiving considerable attention amongst philosophers. I argue that there has been a significant oversight within this field concerning the possibility that many joint actions are driven, at least in part, by agents' social motivations rather than merely by their shared intentions. Social motivations are not directly related to the (joint) target goal of the action. Instead, when agents are mutually socially motivated (...) in joint action this is because they find acting with others rewarding in its own right. Moreover the involvement of social motivation in joint action typically enables individuals to achieve the long-term benefits associated with being part of a social bond. I argue that taking social motivations into account better prepares us for explaining a broader range of joint actions, including those that are of an antagonistic, competitive, or explorative character. Finally, I show that recognizing the importance of social motivations entails that joint actions (in general) should be understood as having the two primary functions of (1) achieving the intended target outcome of an action, and (2) attaining the benefits related to being part of a social bond.

Implicit God-like and ghost-in-the-machine metaphors underlie much current thinking about genomes. Although many criticisms of such views exist, none have succeeded in substituting a different, widely accepted view. Viewing the genome with its protein packaging as a brain gets rid of Gods and ghosts while plausibly integrating machine and information-based views. While the ‘wetware’ of brains and genomes are very different, many fundamental principles of how they function are similar. Eukaryotic cells are compound entities in which case the nuclear genome (...) might best be thought of more as a government than simply as a brain. (shrink)

This essay discusses the nature of collective responsibility and explores various controversies associated with its possibility and normative value.

This paper aims to build a bridge between two areas of philosophical research, the structure of kinds and metaphysical modality. Our central thesis is that kinds typically involve super-explanatory properties, and that these properties are therefore metaphysically essential to natural kinds. Philosophers of science who work on kinds tend to emphasize their complexity, and are generally resistant to any suggestion that they have “essences”. The complexities are real enough, but they should not be allowed to obscure the way that kinds (...) are typically unified by certain core properties. We shall show how this unifying role offers a natural account of why certain properties are metaphysically essential to kinds. (shrink)

The problems of racism and racially motivated violence in predominantly African American communities in the United States are complex, multifactorial, and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development, and (...) academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others. (shrink)

I argue that there is a tension between the claim that at least some kinds in the special sciences are multiply realized and the claim that the reason why kinds are prized by science is that they enter into a variety of different empirical generalizations. Nevertheless, I show that this tension ceases in the case of ‘cultural homologues’—such as specific ideologies, religions, and folk wisdom. I argue that the instances of such special science kinds do have several projectable properties in (...) common due to their shared history of reproduction, and that the social learning involved means that we should also expect these kinds to be multiply realized.

Both Walter Sinnott-Armstrong and Baylor Johnson hold that under current circumstances, individuals lack obligations to reduce their personal contributions to greenhouse gas emissions. Johnson argues that climate change has the structure of a tragedy of the commons, and that there is no unilateral obligation to reduce emissions in a commons. Against Johnson, I articulate two rationales for an individual obligation to reduce one's greenhouse gas emissions. I first discuss moral integrity, which recommends congruence between one's actions and positions at the (...) personal and political levels. Second, I draw on a Confucian, relational conception of persons to offer a critique of the collective action/tragedy of the commons framework itself. Under the relational conception, commons problems can be reconceptualised so as to dissolve the stark contrast between the individually and the collectively rational. This perspective can inform our approach to climate change and help reconcile individual and political action to mitigate it. (shrink)

In this article I examine some of the issues involved in taking psychiatric disorders as natural kinds. I begin by introducing a permissive model of natural kind-hood that at least prima facie seems to allow psychiatric disorders to be natural kinds. The model, however, hinges on there in principle being some grounding that is shared by all members of a kind, which explain all or most of the additional shared projectible properties. This leads us to the following question: what grounding (...) do psychiatric disorders qua natural kinds have? My principal method for examining the issue is a case study of a particular psychiatric disorder: the so-called “apathetic children.” I argue that there appear to be at least two competing models that both appeal to non-organic a grounding of the disorder. However, for other psychiatric disorders, such as Alzheimer’s disease, the evidence points toward an organic explanation of the disorder. I contend that what unites psychiatric disorders is not a distinctive type of grounding that all psychiatric disorders share, but the distinctive set of determinable properties that is shared by all psychiatric disorders.

BackgroundThe increasing emphasis on research, development and innovation for health in providing solutions to the high burden of diseases in the African Region has warranted a proliferation of studies including clinical trials. This changing public health landscape requires that countries develop adequate ethics review capacities to protect and minimize risks to study participants. Therefore, this study assessed the readiness of national ethics committees to respond to challenges posed by a globalized biomedical research system which is constantly challenged by new public (...) health threats, rapid scientific and technological advancements affecting biomedical research and development, delivery and manufacture of vaccines and therapies, and health technology transfer.MethodsThis is a descriptive study, which used a questionnaire structured to elicit information on the existence of relevant national legal frameworks, mechanisms for ethical review; as well as capacity requirements for national ethics committees. The questionnaire was available in English and French and was sent to 41 of the then 46 Member States of the WHO African Region, excluding the five Lusophone Member States. Information was gathered from senior officials in ministries of health, who by virtue of their offices were considered to have expert knowledge of research ethics review systems in their respective countries.ResultsThirty three of the 41 countries responded. Thirty of respondent countries had a national ethics review committee ; 79 % of which were established by law. Twenty-five NECs had secretarial and administrative support. Over 50 % of countries with NECs indicated a need for capacity strengthening through periodic training on international guidelines for health research ethics; and allocation of funds for administrative and secretariat support.ConclusionsDespite the existing training initiatives, the Region still experiences a shortage of professionals trained in health research ethics/ethicists. Committees continue to face various capacity needs especially for evaluating clinical trials, for monitoring ongoing research, database management and for accrediting institutional ethics committees. Given the growing number of clinical trials involving human participants in the African Region, there is urgent need for supporting countries without NECs to establish them; capacity strengthening where they exist; and creation of a regional network and joint ethical review mechanisms, whose membership would be open to all NECs of the Region.

Elles sont privilégiées d’un point de vue ontologique parce que la deixis grâce à laquelle leur sujet fait référence au réel crée une relation privilégiée à (...) la matière, la catégorie ontologique stoïcienne fondamentale. De plus, ces sujets requièrent que leur référent existe et soit présent et saisissable.

Nous suggérons enfin que tous les énoncés apparemment définis ne le sont pas en effet, et considérons quand et sous quelles conditions une référence déictique est réussie. (shrink)

This pioneering book demonstrates the crucial importance of Wittgenstein's philosophy of mathematics to his philosophy as a whole. Marion traces the development of Wittgenstein's thinking in the context of the mathematical and philosophical work of the times, to make coherent sense of ideas that have too often been misunderstood because they have been presented in a disjointed and incomplete way. In particular, he illuminates the work of the neglected 'transitional period' between the Tractatus and the Investigations.

Family members can provide crucial support to individuals participating in clinical trials. In research on the “newest frontier” of Deep Brain Stimulation (DBS)—the use of DBS for psychiatric conditions—family member support is frequently listed as a criterion for trial enrollment. Despite the significance of family members, qualitative ethics research on DBS for psychiatric conditions has focused almost exclusively on the perspectives and experiences of DBS recipients. This qualitative study is one of the first to include both DBS recipients and their (...) family members as interview participants. Using dyadic thematic analysis—an approach that takes both the individuals and the relationship as units of analyses—this study analyzes the complex ways in which family relationships can affect DBS trial participation, and how DBS trial participation in turn influences family relationships. Based on these findings, we propose ways to improve study designs to better take family relationships into account, and better support family members in taking on the complex, essential roles that they play in DBS trials for psychiatric conditions.

In order to explore public views on nanobiotechnology (NBT), convergence seminars were held in four places in Europe; namely in Visby (Sweden), Sheffield (UK), Lublin (Poland), and Porto (Portugal). A convergence seminar is a new form of public participatory activity that can be used to deal systematically with the uncertainty associated for instance with the development of an emerging technology like nanobiotechnology. In its first phase, the participants are divided into three “scenario groups” that discuss different future scenarios. In the (...) second phase, the participants are regrouped into three “convergence groups”, each of which contains representatives from each of the three groups from the first phase. In the final third phase, all participants meet for a summary discussion. This pilot project had two aims: (1) to develop and assess the new methodology and (2) to gather advice and recommendations from the public that may be useful for future decisions on nanobiotechnology (NBT). Participants emphasized that they wanted the technology to focus on solutions to environmental and medical problems and to meet the needs of developing countries. The need for further public participation and deliberation on NBT issues seemed to be acknowledged by all participants. Many of them also raised equality concerns. Views on the means by which NBT should be steered into socially useful directions were more divided. In particular, different views were expressed on how much regulation of company activities is needed to curb unwanted developments. The participants’ responses in a questionnaire indicate that the methodology of the convergence seminars was successful for decision-making under uncertainty. In particular, the participants stated that their advice was influenced both by access to different possible future developments and by the points of view of their co-participants, which is what the method is specifically intended to achieve.
