Biology is seen not merely as a privileged oppressor of women but as a co-victim of masculinist social assumptions. We see feminist critique as one of the normative controls that any scientist must perform whenever analyzing data, and we seek to demonstrate what has happened when this control has not been utilized. Narratives of fertilization and sex determination traditionally have been modeled on the cultural patterns of male/female interaction, leading to gender associations being placed on cells and their components. (...) We also find that when gender biases are controlled, new perceptions of these intracellular and extracellular relationships emerge. (shrink)

In this article, I contrast two of the main schools of thought within eco-Marxism, namely Metabolic Rift (MR) and World-Ecology (WE). These differ above all else in their accounts of the ontological status of society and nature. The Covid-19 pandemic constitutes a moment of concretisation of this long-standing debate, which is able to dissolve at least in part its issues. The article consists of four parts. I begin with a summary of the two schools of thought and their core stances, (...) before proceeding to unpack their respective theoretical points of contention. I subsequently proceed to explore the conceptualisation of health according to the Marxist scientists Richard Levins and Richard Lewontin through the model of dialectical biology. In the third section, I unpack the conceptualisation of the Covid-19 pandemic by the epidemiologist Robert Wallace, before finally concluding with the contrasts of the two schools in the light of dialectical biology.

I argue in this paper that rather than viewing John Dewey as either a historicist or a naturalist, we should see him as strange but potentially fruitful combination of both. I will demonstrate that the notion of organism-environment interaction central to Dewey’s pragmatism stems from a Hegelian approach to adaptation; his turn to biology was not necessarily a turn away from Hegel. I argue that Dewey’s account of the organism-environment relation derives from the work of Oxford Hegelians such as (...) Edward Caird and Samuel Alexander, who were attempting to reconcile evolutionary ideas with a critique of Herbert Spencer’s environmentalist account of human thought and action. This dialectical account of organism-environment interaction played a key role in Dewey’s philosophy from the 1890s to the 1940s, despite other shifts in his thinking. (shrink)

The aim of this hermeneutic study was to gain a broader understanding of nurses’ workload and what characterizes a nurse’s experience in terms of the various levels of intensity of nursing care. Twenty-nine nurses participated in seven focus groups. The interpretation process took place in six different phases and the three laws of dialectics were used as interpretation rules. An optimal nursing care intensity level can be understood as a situation characterized by the balance between the intensity of care (...) needed by patients and the external and internal factors of the current nursing care situation. The nurses’ work situation can be understood as a dialectic struggle between ‘being’ and ‘not being’ a good nurse; this can be said to be the underlying root metaphor. Nursing care can be understood as consisting of ‘complex and meaningful caring situations’. Dialectics can be used as a fruitful method of revealing the complexity of clinical reality. (shrink)

The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...) been a focus in some recent discussions by both philosophers and biologists on how evolutionary individuals are created and regulated, as well as continuing work on the evolution of individuality.

Throughout, this book questions our accepted definitions and biases, showing the self-reflective nature of scientific activity within society.

This article illustrates how axiomatic social choice theory can be used in the evaluation of measures of group fitness for a biological hierarchy, thereby contributing to the dialogue between the philosophy of biology and social choice theory. It provides an axiomatic characterization of the ordering underlying the MichodSolariNedelcu index of group fitness for a multicellular organism. The MVSHN index has been used to analyse the germ-soma specialization and the fitness decoupling between the cell and organism levels that (...) takes place during the evolutionary transition to multicellularity. It is argued that some of the axioms satisfied by the MVSHN group fitness ordering are not appropriate for all stages in this transition. (shrink)

The ‘Dialectical school’ denotes a group of early Hellenistic philosophers that were loosely connected by philosophizing in the — Socratic — tradition of Eubulides of Megara and by their interest in logical paradoxes, propositional logic and dialectical expertise. . Its two best known members, Diodorus Cronus and Philo the Logician, made groundbreaking contributions to the development of theories of conditionals and modal logic. Philo introduced a version of material implication; Diodorus devised a forerunner of strict implication. Each developed a (...) system of modal notions that satisfies the basic logical requirements laid down by modern standard modal theories. In antiquity, Diodorus Cronus was famous for his so called Master Argument, which aims to prove that only the actual is possible. (shrink)

Our current work examined the interface between thinking style and emotional experience at both the behavioral and neuropsychological levels. Thirty-nine Chinese participants completed the triad task, and we calculated the rate of individually selected relationship pairings to overall selections to represent their holistic thinking tendencies. In addition, participants in the top one-third of the ratio score were classified into the high holistic thinking group, while those in the bottom one-third of the ratio score were classified into the low holistic (...) thinking group. We used the sensitivity to punishment and sensitivity to reward questionnaire to examine how people elicit positive and negative affective behaviors. Additionally, we examined the volume of the amygdala and nucleus accumbens and their functional connectivity in the resting-state. We found that high holistic thinkers were much less sensitive to rewards than low holistic thinkers. In other words, individuals with high holistic thinking are less likely to pursue behaviors that have positive emotional outcomes. Furthermore, their bilateral nucleus accumbens and right amygdala volumes were smaller than those of low holistic thinkers. Hierarchical regression analysis showed that holistic thinking tendency can negatively predict the volume of the left nucleus accumbens and right amygdala. Finally, resting-state functional connectivity results showed increased functional connectivity FC between left nucleus accumbens and bilateral amygdala in high holistic thinkers. These findings provide emotion-related manifestations of thinking styles at the behavioral and neural levels. (shrink)

Phenomena like meat sharing in hunter-gatherers, altruistic self-sacrifice in intergroup conflicts, and contribution to the production of public goods in laboratory experiments have led to the development of numerous theories trying to explain human prosocial preferences and behavior. Many of these focus on direct and indirect reciprocity, assortment, or (cultural) group selection. Here, I investigate analytically how genetic relatedness changes the incentive structure of that paradigmatic game which is conventionally used to model and experimentally investigate collective action problems: the (...) public goods game. Using data on contemporary hunter-gatherer societies I then estimate a threshold value determining when biological altruism turns into maximizing inclusive fitness in this game. I find that, on average, contributing no less than about 40% of individual fitness to public goods production still is an optimal strategy from an inclusive fitness perspective under plausible socio-ecological conditions.

Biology above the level of the individual organism ? population ecology and genetics, community ecology, biogeography and evolution ? requires the study of intrinsically complex systems. But the dominant philosophies of western science have proven to be inadequate for the study of complexity:(1)The reductionist myth of simplicity leads its advocates to isolate parts as completely as possible and study these parts. It underestimates the importance of interactions in theory, and its recommendations for practice (in agricultural programs or conservation and (...) environmental protection) are typically thwarted by the power of indirect and unanticipated causes rather than by error in the detailed description of their own objects of study.(2)Reductionism ignores properties of complex wholes; the effects of these properties are therefore seen only as noise; this randomness is elevated into an ontological principle which leads to the blocking of investigation and the reification of statistics, so that data reduction and statistical prediction often pass for explanation.(3)The faith in the atomistic nature of the world makes the allocation of relative weights to separate causes the main object of science, and makes it more difficult to study the nature of interconnectedness.

Many scientific models in biology are how-possibly models. These models depict things as they could be, but do not necessarily capture actual states of affairs in the biological world. In contemporary philosophy of science, it is customary to treat how-possibly models as second-rate theoretical tools. Although possibly important in the early stages of theorizing, they do not constitute the main aim of modelling, namely, to discover the actual mechanism responsible for the phenomenon under study. In the paper it is (...) argued that this prevailing picture does not do justice to the synthetic strategy that is commonly used in biological engineering. In synthetic biology, how-possibly models are not simply speculations or eliminable scaffolds towards a single how-actually model, but indispensable design hypotheses for a field whose ultimate goal is to build novel biological systems. The paper explicates this by providing an example from the study of alternative genetic systems by synthetic biologist Steven Benner and his group. The case will also highlight how the method of synthesis, even when it fails, provides an effective way to limit the space of possible models for biological systems. (shrink)

Our bodies are ourselves: yet we are also more than our bodies. In the early years of “second‐wave” feminism in the West, embodiment was acknowledged implicitly in the action of women's health groups, and campaigns for reproductive rights. But simultaneously, bodies failed to enter our theorizing. Central to theorizing then was a distinction between “sex,” (which anatomically distinguishes males and females) from “gender” (the processes of becoming “woman” or “man”). Although recent feminist writing tends to decry that simple opposition, the (...) ghost of biology still haunts us: biological sex, the biological body, remain problematic concepts for feminist theorizing.

In the 1950s, embryology in socialist China underwent a series of changes that adjusted the disciplinary apparatus to suit socialism and the national goal of self-reliance. As the Communist state called on scientists to learn from the Soviets, embryologists’ comprehensive view on heredity, which did not contradict Trofim Lysenko ’s doctrines, provided a space for them to advance their discipline. Leading scientists, often trained abroad in the tradition of experimental embryology, rode on the tides of Maoist ideology and repositioned their (...) research. Some of their creative realignment of previous research questions, materials, and traditions to Marxist philosophy and agricultural objectives generated productive programs. In particular, Tong Dizhou translated Engels’s dialectics of nature into a research question about cytoplasmic inheritance. His continuing investigation on it led to the first goldfish “clone” through a nuclear transplantation experiment; Zhu Xi and his associates transferred a goldfish model in embryology into studies on improving carp aquaculture, leading to a rare success in the Great Leap Forward of 1958. These directions for embryology continued well into the 1960s. At a time when global embryology was diversifying and began to be molecularized, eventually forming “developmental biology,” socialist embryology took shape in China with a different set of epistemic and practical commitments. The history of its development challenges and enriches our understanding of the concrete process of change in one discipline under Mao, showing ways in which scientists creatively adapted state-sanctioned ideologies and visions to do productive work outside the framework of molecular biology during the Cold War.

The first part of this paper has shown that the development of regulatory genetics and the lactose operon model stemmed from laboratory cultures rooted in local traditions. A "physiological" culture may be recognized in the Pasteurian context. The institutional continuity provided the basis for a tenuous link between Pasteur, Lwoff, and Monod. My claim is that the "national" value of regulatory and physiological genetics is an artifact produced in the course of the legitimization process accompanying the institutionalisation of the discipline. (...) In the 1960s, the lactose operon model was turned into a "flag-object," a symbol of the new culture. The work done by the Pasteurian group became therefore the most important, if not the only, exemplar of molecular biology in France.The second part o f the paper described the origins of general patterns that dominated the building of molecular biology in France. The study of the relationships between molecular biologists and biochemists or immunologists revealed the existence of alternatives to the development of operon research, or to the convergence with molecular biology. Both examples uncover specific paths leading to achievements that might be viewed as international trends: the expansion of RNA and translation studies, and the development of cellular immunology. They illustrate two possible patterns of linking local settings and disciplinary traditions: an oligopolistic situation where a few groups or one institution dominate an entire field, and the emergence of "collective" trends through collaboration networks or schools.

RESUMOO presente artigo analisa processos de alterização na biologia humana e na biomedicina. A alterização é entendida aqui como o processo cultural de produção de alteridades por meio da delimitação, rotulação e categorização das formas possíveis de ser outro, desde um determinado marco de referência sócio-histórico. Ainda que a alterização faça parte de qualquer processo de delimitação de categorias de identidade no seio de uma cultura - e, nesse sentido, possa apresentar visões do outro tanto positivas quanto negativas -, aqui (...) nos interessamos especificamente na alterização como fator de marginalização e exclusão social de diferentes grupos humanos. São analisados diversos processos de alterização operantes nos discursos e nas práticas das ciências biomédicas ao longo de sua história recente, os quais têm conduzido à exclusão social de diferentes categorias de outros, ou a tratá-los como inferiores, em pretendidas bases científicas, ou em função de determinadas práticas institucionalizadas dentro da comunidade científica. Exemplos típicos de grupos marginalizados pelas ciências ocidentais ao longo de sua história incluem as raças não europeias, as mulheres, os homossexuais e os "pobres". O principal objetivo do presente artigo é analisar, na história recente das ciências biomédicas, esses processos de alterização que têm conduzido à marginalização de tais grupos e a considerá-los como inferiores. ABSTRACTThis article analyzes processes of "othering" in human biology and biomedicine. Othering is understood here as the cultural process of production of otherness by means of the delimitation, tagging, and categorization of the possible ways of being "other" within a given socio-historical context. Although othering can be considered as a constitutive aspect of any process of delimitation of identities within a given culture - and in this sense it can present both positive and negative views of the "other" -, in the present article we are specifically interested in processes of othering that lead to the marginalization and social exclusion of different human groups. We will analyze processes of othering, which have operated in the discourses and practices of biomedical sciences throughout their recent history, that have led to the social exclusion of different categories of "others", or to treating them as inferior, and that have supposedly scientific bases or as a consequence of the institutionalization of certain practices within the scientific community. Typical examples of these "others", marginalized by the Western sciences throughout their history, are the non-European "races", women, gay and lesbian people, and the "poor". The main objective of this article is to analyze, in the recent history of the biomedical technosciences, these different processes of othering that have led to the marginalization of such "others" and to treating them as inferior.

Dialogue is a seminal concept within the work of the Brazilian adult education theorist, Paulo Freire, and the Russian literary critic and philosopher, Mikhail Bakhtin. While there are commonalities in their understanding of dialogue, they differ in their treatment of dialectic. This paper addresses commonalities and dissonances within a Bakhtin-Freire dialogue on the notions of dialogue and dialectic. It then teases out some of the implications for education theory and practice in relation to two South African contexts of learning that (...) facilitate the access to education of disadvantaged groups, one in higher education and the other in early childhood education.

Difficulties with the typological concept of species led biologists to reject the "typological" presupposition of an archetype which is manifest in each member of a species. The resulting concept of species, which is here called the phenotypic species concept, is considered as implying that biological species are not real. Modern population thinking has given rise to the concept of a species as a gene-pool. This modern concept is contrasted here with the phenotypic concept in light of some general criteria for (...) evaluating species concepts and is shown to be more satisfactory. Finally, it is held that to ask if a species is real is to ask whether the species grouping arrived at by applying the principles involved in the species concept corresponds with groups of organisms amongst which important biological relationships exist. It is argued that in this sense species, as defined by the gene-pool concept, are certainly real. (shrink)

Problems of sustainability and survivability are best met not with moralizing but with policies that take advantage of our increasingly understood evolved human psychology. This knowledge helps us understand why our problems recur, and why we need not expect them to have permanent solutions. What is needed is an evolutionary praxis. It is possible, for example, to create policies that work around our tendencies to hierarchize and to form into ethnocentric and mutually hostile groups. Although in many ways there may (...) be a mismatch between our evolved human nature and contemporary society, the fact that it is we who construct our environments must reduce the extent of mismatch.

The ambition of this article is to propose a way of visualizing the Anthropocene dialectically. As suggested by the Dutch atmospheric chemist Paul Crutzen and the professor of biology Eugene F. Stoermer, the term Anthropocene refers to a historical period in which humankind has turned into a geological force that transforms the natural environment in such a way that it is hard to distinguish between the human and the natural world. Crutzen and Stoermer explain that the Anthropocene has begun (...) after the Holocene, the geological epoch that followed the last ice age and lasted until the industrial revolution. Drawing on a number of figures such as the “tenfold” increase in urbanisation, the extreme transformation of land surface by human action, the use of more than 50% of all accessible fresh water by humans, and the massive increase in greenhouse emissions, Crutzen and Stoermer conclude that the term Anthropocene describes aptly mankind's influence on ecological and geological cycles (Crutzen & Stoermer, 20...

The idea that Adorno should be read as a “realist” of any sort may indeed sound odd. And unpacking from Adorno’s elusive prose a credible and useful normative reconstruction of epistemology and metaphysics will take some work. But we argue that he should be added to the growing group of epistemologists and metaphysicians who have been developing post-positivist versions of realism such as contextual, internal, pragmatic and critical realisms. These latter realisms, however, while helpfully showing how realism can coexist (...) with ontological pluralism, for example, as well as a highly contextualised account of knowledge, have not developed a political reflexivity about how the object of knowledge—the real—is constructed. As a field, then, post-positivist realisms have been politically naïve, which is perhaps why they have not enjoyed more influence among Continental philosophers. (shrink)

Altruism may be learned (behavioral evolution) in a way similar to that proposed in the target article for its biological evolution. Altruism (over social space) corresponds to self-control (over time). In both cases, one must learn to ignore the rewards to a particular (person or moment) and behave to maximize the rewards to a group (of people or moments).

A physiological function can be described as a cycle based on a cusp bifurcation set in catastrophe theory. This cycle involves four phases that are successively developed along a functional potential, which is used to perform a given physiological act. The work we present is firstly based on a detailed study of the global function of vision, which covers a vast field extending from the molecular to cerebral scale. We then present other examples of generalised functions by expanding the frame (...) of reference, from the scale of an organ to the scale of a whole organism with predation function, and to the scale of a social group with crisis management. We observed that the criteria remain the same, whether the function is considered on the scale of a cell membrane or a group of individuals organised into a cohort. Moreover, a so-called generalised function can be broken down into simpler sub-functions, each phase of the initial function containing the physiological act of each sub-function. It seems thus that a fractal extension may characterise the four-cusp spiral. This spiral is increasingly large as the types of sub-functions are multiplied. In functions relative to sociological science, such as crisis management, which are not natural but built and designed by humans, close attention must be paid to following the rules of these generalised biological functions.

The question on how the diverse forms of cooperative behavior in humans and nonhuman animals could have evolved under the pressure of natural selection has been a challenge for evolutionary biology ever since Darwin himself. In this chapter, we briefly review and summarize results from the last 50 years of research on human and nonhuman cooperativeness from a theoretical (biology) and an experimental perspective (experimental economics). The first section presents six concepts from theoretical biology able to explain (...) a variety of forms of cooperativeness which evolved in many different species. These are kin selection, mutualism, reciprocity, green-beard altruism, costly signaling, and cultural group selection. These considerations are complemented by two short examples of evolved cooperative behavior, one from microbiology and one from ethology. The second main section focuses on recent experimental research on human cooperativeness. We present a brief review of factors known to impact individual human decision-making in social dilemmas, most prominently communication, punishment, reputation, and assortment. Our conclusion then draws attention to tasks for further research in this area. (shrink)

One way in which philosophy of science can perform a valuable normative function for science is by showing characteristic errors made in scientific research programs and proposing ways in which such errors can be avoided or corrected. This paper examines two errors that have commonly plagued research in biology and psychology: 1) functional localization errors that arise when parts of a complex system are assigned functions which these parts are not themselves able to perform, and 2) vacuous functional explanations (...) in which one provides an analysis that does account for the inputs and outputs of a system but does not employ the same set of functions to produce this output as does the natural system. These two kinds of error usually arise when researchers limit their investigation to one type of evidence. Historically, correction of these errors has awaited researchers who have employed the opposite type of evidence. This paper explores the tendency to commit these errors by examining examples from historical and contemporary science and proposes a dialectical process through which researchers can avoid or correct such errors in the future.

In view of the new forays from biology into the Humanities, this book aims not only to demonstrate the inconsistencies of the theory of evolution in addressing cultural dynamics, but also to offer an alternative that begins from a resumption of the dialogue between anthropology and historical materialism in which dialectics reintroduces itself to anthropology from different premises and the role of symbolic language within materialism is reevaluated.

Observers have noted a decline (in the US) in attributions of genetically-based inferiority (e.g. in intelligence) to Blacks, and a rise in attributions of culturally-based inferiority. Is this "culturalism" merely warmed-over racism ("cultural racism") or a genuinely distinct way of thinking about racial groups? The question raises a larger one about the relative place of biology and culture in racist thought. I develop a typology of culturalisms as applied to race: (1) inherentist or essentialist culturalism (inferiorizing cultural characteristics wrongly (...) but intelligibly regarded as inhering in the nature of racial groups). This view has an historical pedigree in the work of J.G. von Herder, and the tradition of "national racism." (2) non-inherentist culturalism (groups regarded as possessing changeable, malleable inferiorizing cultural characteristics). (3) colonalist culturalism (colonial subjects regarded as uncivilized but capable of becoming civilized under European tutelage). (4) neo-racism (cultures of former colonial subjects in or potentially immigrating to European countries are regarded in an inherentist manner and incompatible with but not inferior to European cultures). Non-inherentist culturalism (#2) can be put to either a racist or an anti-racist use. (shrink)

This paper describes the first phase of an ongoing education and research project guided by three main intentions: (1) to create opportunities for phronesis in the classroom; (2) to develop new understandings about phronesis as it relates to nursing care generally and to caring for specific groups, like formerly incarcerated adults; and (3) to provide an opportunity for formerly incarcerated adults and graduate nursing students to participate in a dialectical conversation about ethical knowing. Gadamer's writings on practical philosophy, phronesis, and (...) the Socratic dialectic provide the philosophical foundation and framework for the project. The first phase in the project was a 4‐h class within a graduate‐level health promotion course during which 30 nursing students and three formerly incarcerated panelists engaged in a dialectic conversation about what it means to care for formerly incarcerated adults in a meaningful way. After the class, two focus groups were conducted, one with the students and one with the formerly incarcerated panelists. Findings articulated participants' prejudices and assumptions prior to the class, expanded sense of phronesis, and ability to consider nursing practice within a larger ethical framework. Panelists and students left the class with a deeper understanding of one another and expressed an openness towards continued dialectic conversations together. Use of the Socratic dialectic within nursing curricula reflects a current and critical trend in nursing education to bring non‐epistemologic forms of knowledge into the classroom. (shrink)

Answering a call for a 2013 exhibition at Ars Electronica bridging art and synthetic biology, a group of artists and designers offer ‘Blueprints for the Unknown’. Their fictional scenarios offer possible futures already embedded in and ready to become our present. By imagining potential events and soon-to-be organisms and bodies, these blueprints perform the untenable relationship between predictable bioengineered living forms and the unpredictable contexts within which such life subsists over time. While synthetic biology focuses on the (...) particularities of each micro-manipulation within a specific timeframe, art practices can speculate on the wider reverberations of modified life, making visible the vulnerable encounters and uneven exchanges across variable living forms and scales, from molecule to human, synthetic to organic. This paper explores the indeterminacies that arise as living forms become synthetically modified, reorganized and redirected at will. (shrink)

Biological sexes (male, female, hermaphrodite) are defined by different gametic strategies for reproduction. Sexes are regions of phenotypic space which implement those gametic reproductive strategies. Individual organisms pass in and out of these regions – sexes - one or more times during their lives. Importantly, sexes are life-history stages rather than applying to organisms over their entire lifespan. This fact has been obscured by concentrating on humans, and ignoring species which regularly change sex, as well as those with non-genetic or (...) facultatively genetic sex determination systems. But the general point applies equally to humans. Assigning sexes to pre-reproductive life history stages involves ‘prospective narration’ – classifying the present in terms of its anticipated future. Assigning sexes to adult stages of non-reproductive castes or non-reproductive individuals is a complex matter whose biological meaning differs from case to case. The chromosomal and phenotypic ‘definitions’ of biological sex that are contested in philosophical discussions of sex are actually operational definitions which track gametic sex more or less effectively in some species or group of species. Neither ‘definition’ can be stated for species in general except by defining them in terms of gametic sex. The gametic definition of sex also features in widely accepted models which explain why two biological sexes – either in separate individuals or combined in hermaphroditic individuals - are almost universal in multicellular species. Finally, the fact that a species has only two biological sexes does not imply that every member of the species is either male, female or hermaphroditic, or that the sex of every individual organism is clear and determinate. The idea of biological sex is critical for understanding the diversity of life, but ill-suited to the job of determining the social or legal status of human beings as men or women. (shrink)

This commentary proposes experiments to examine connections between the presence of out-group members, neurovisceral reactions, religiosity, and ethnocentrism, to clarify the meaning of the correlational findings presented in the target article. It also suggests different ways of describing religious socialization and of viewing assertions about religion and health or about the human ability to detect pathogens.

Synthetic biology is a cutting-edge area of research that holds the promise of unprecedented health benefits. However, in tandem with these large prospective benefits, synthetic biology projects entail a risk of catastrophic consequences whose severity may exceed that of most ordinary human undertakings. This is due to the peculiar nature of synthetic biology as a ‘threshold technology’ which opens doors to opportunities and applications that are essentially unpredictable. Fears about these potentially unstoppable consequences have led to declarations (...) from civil society groups calling for the use of a precautionary principle to regulate the field. Moreover, the principle is prevalent in law and international agreements. Despite widespread political recognition of a need for caution, the precautionary principle has been extensively criticized as a guide for regulatory policy. We examine a central objection to the principle: that its application entails crippling inaction and incoherence, since whatever action one takes there is always a chance that some highly improbable cataclysm will occur. In response to this difficulty, which we call the ‘precautionary paradox,’ we outline a deliberative means for arriving at threshold of probability below which potential dangers can be disregarded. In addition, we describe a Bayesian mechanism with which to assign probabilities to harmful outcomes. We argue that these steps resolve the paradox. The rehabilitated PP can thus provide a viable policy option to confront the uncharted waters of synthetic biology research. (shrink)

Advances in genetics may soon make possible the development of ethnic bioweapons that target specific ethnic or racial groups based upon genetic markers. While occasional published reports of such research generate public outrage, little has been written about the ethical distinction (if any) between the development of such weapons and ethnically neutral bioweapons. The purpose of this paper is to launch a debate on the subject of ethnic bioweapons before they become a scientific reality.

Abstract. Biology has been able to systematize and order its vast information through the theory of evolution, offering the possibility of a more engaged dialogue and possible integration with religious insights and emotions. Using Judaism as a focus, this essay examines ways that contemporary evolutionary theory offers room for balancing freedom and constraint, serendipity and intentionality in ways fruitful to Jewish thought and expression. This essay then looks at a productive integration of Judaism and biology in the examples (...) of co-evolution, environmental ethics, the place of humans within nature, the relationship of mind and brains, and the ways that individual and group identity blur.

The minimalist concept of race represents the barest characterization of the ordinary concept race possible. Minimalist races are groups of human beings distinguished by patterns of visible physical features, groups whose members are linked by a common ancestry peculiar to members of the group, and which originate from a distinctive geographic location. Minimalist races exist because there are existing human groups that satisfy the minimalist concept of race. Their existence is not precluded by the findings of population genetics. Appeal (...) to contemporary studies in evolutionary biology and population genetics makes it possible to rebut the objection that minimalist races do not exist because they are not genetically distinct.

This paper provides a critical reflection on the nature of ethnic enclaves and segregation by presenting an analytical frame that can be used to capture the contested nature of spatiality in these spaces. By underscoring the dynamics in which differences constitute distinct subject positions, this paper posits a relational orientation to studying spatiality that is based on complex relations among and between subjects and space. To date, few attempts have been made to present an analytical frame for the analysis of (...) the spatiality of ethnic enclaves and segregation in which space becomes contested by different groups, occupants of space, and those external to space. This paper bridges this gap by synthesizing the relational approaches found in Bourdieusian field theory and Lefebvrian spatiality. This paper seeks to make three contributions. First, to provide an explicit theoretical anchor upon which relational and spatial theories converge since the underlying rationale for complementary is usually only implicitly evaluated. In detailing this convergence, the social constitution of reality and an emphasis on the duality between individuals and society as well as society and space are identified as a rationale for relational spatiality. Second, to demonstrate how a collective engagement with Bourdieu’s and Lefebvre’s approaches facilitates a recognition of spatiality as a polysemous social product and producer of social reality in addition to grounding this orientation as a critical dialectic engagement in which both the subjects and knowledge production cannot be neutral. Third, to present an analytical frame for the investigation of ethnic enclaves in and through which ethnic majorities, minorities, occupants of space, and those external to these enclaves constitute different views towards the same space.

Leading invasion biologists sometimes dismiss critics and criticisms of their field by invoking “the straw man” fallacy. Critics of invasion biology are also labelled as a small group of “naysayers” or “contrarians”, who are sometimes engaging in “science denialism”. Such unfortunate labels can be seen as a way to possibly suppress legitimate debates and dismiss or minimize reasonable concerns about some aspects of invasion biology, including the uncertainties about the geographic origins and complex environmental impacts of species, (...) and the control programs against species perceived as “invasive”. In assessing the quality of the debate in this area, we examine the validity of the use of various strategies, including the “straw man” concept, and explore a range of potential logical fallacies present in some recent prominent discussions about invasion biology and so-called “invasive” species. The goal is to add some clarity to the concepts involved, point out some problematic issues, and improve the quality of the debates as the discussions move forward. (shrink)

This paper addresses theoretical challenges, still relevant today, that arose in the first decades of the twentieth century related to the concept of the organism. During this period, new insights into the plasticity and robustness of organisms as well as their complex interactions fueled calls, especially in the UK and in the German-speaking world, for grounding biological theory on the concept of the organism. This new organism-centered biology understood organisms as the most important explanatory and methodological unit in biological (...) investigations. At least three theoretical strands can be distinguished in this movement: Organicism, dialectical materialism, and holistic biology. This paper shows that a major challenge of OCB was to describe the individual organism as a causally autonomous and discrete unit with consistent boundaries and, at the same time, as inextricably interwoven with its environment. In other words, OCB had to conciliate individualistic with anti-individualistic perspectives. This challenge was addressed by developing a concept of life that included functionalist and metabolic elements, as well as biochemical and physical ones. It allowed for specifying organisms as life forms that actively delimit themselves from the environment. Finally, this paper shows that the recent return to the concept of the organism, especially in the so-called “Extended Evolutionary Synthesis,” is challenged by similar anti-individualistic tendencies. However, in contrast to its early-twentieth-century forerunner, today’s organism-centered approaches have not yet offered a solution to this problem. (shrink)

Philosophy can shed light on mathematical modeling and the juxtaposition of modeling and empirical data. This paper explores three philosophical traditions of the structure of scientific theory—Syntactic, Semantic, and Pragmatic—to show that each illuminates mathematical modeling. The Pragmatic View identifies four critical functions of mathematical modeling: (1) unification of both models and data, (2) model fitting to data, (3) mechanism identification accounting for observation, and (4) prediction of future observations. Such facets are explored using a recent exchange between two groups (...) of mathematical modelers in plant biology. Scientific debate can arise from different modeling philosophies. (shrink)

ABSTRACTIndividual differences in the habitual use of emotion regulation strategies may play a critical role in understanding psychological and biological stress reactivity and recovery in depression and anxiety. This study investigated the relation between the habitual use of different emotion regulation strategies and cortisol reactivity and recovery in healthy control individuals and in individuals diagnosed with social anxiety disorder. The tendency to worry was associated with increased cortisol reactivity to a stressor across the full sample. Rumination was not associated with (...) cortisol reactivity, despite its oft-reported similarities to worry. Worry and rumination, however, were associated with increased cortisol during recovery from the stressor. The only difference between CTL and SAD participants was observed for reappraisal. In the CTL but not in the SAD group, reappraisal predicted recovery, such that an increased tendency to reappraise was associated with greater c... (shrink)

In a recent article in Philosophy of Science Janet Travis [13] seeks to refute the argument for evolutionary progressivism which is based on a series of dominant life forms on the grounds that there is no rigorous definition of that concept. In particular she claims that the definitions formulated by Sir Julian Huxley and George Gaylord Simpson fail adequately to exclude any group of organisms. The concept of dominance is therefore alleged to be meaningless and the argument for progress (...) invalid. (shrink)

A central challenge for research on how we should prepare students to manage crossing boundaries between different knowledge settings in life long learning processes is to identify those forms of knowledge that are particularly relevant here. In this paper, we develop by philosophical means the concept of a dialectical system as a general framework to describe the de-velopment of knowledge networks that mark the starting point for learning processes, and we use semiotics to discuss the epistemological thesis that any cognitive (...) access to our world of objects is mediated by signs and diagrammatic reasoning and abduction as those forms of practical knowledge that are crucial for the development of knowledge networks. The rich-ness of this theoretical approach becomes evident by applying it to an example of learning in a biological research context. At the same time, we take a new look at the role of mathematical knowledge in this process. (shrink)

Purpose: The purpose of this mixed-methods study was to determine whether Facebook use affects biological response to stress and to characterize participants’ use of Facebook during a stressful event. Methods: College students completed a modified Trier Social Stress Test including video recording. Participants were randomly assigned to the Facebook group or control group (no preparatory materials). Pulse and salivary cortisol were measured and compared using t tests. Trained coders assessed videos for 13 common Facebook actions and categorized them (...) as purposeful (tool based) or nonpurposeful (distraction); pulse was compared between groups using Fisher’s exact test. Results: Of 41 participants, 14 (36%) were male and 36 (88%) were Caucasian, mean age was 19.6 ± 1.4 years; 19 participants were randomized to the Facebook group. Comparing Time 1 and Time 3, there were no significant differences in cortisol or pulse change between the Facebook group and the control group. However, males in the control group had a mean pulse reduction of −3.5 ± 0.2 bpm between baseline and Time 3; males in the Facebook group had a mean pulse increase of 10 ± 8.6 bmp (p =.01). Overall, 58.8% of videos were categorized as primarily tool based. Participants who primarily demonstrated distracted use of Facebook had higher than average pulse rates at Time 3 (mean 85.1 vs. 73.6 bpm, p =.03). Discussion: Male Facebook users and participants who demonstrated distracted Facebook use showed increased biologic signs of stress during a stressful event. Some college students may find Facebook use detrimental to performance in stressful situations, but this may vary by gender and type of use. (shrink)
