This dissertation contributes to the development of philosophy of disability by drawing on disability studies, feminist philosophy, phenomenology, and philosophy of biology in order to contest epistemic and ontological assumptions about disability within biomedical ethics as well as within philosophical work on the body, demonstrating how philosophical inquiry is radically transformed when experiences of disability are taken seriously. In the first two chapters, I focus on epistemological and ontological concerns surrounding disability within biomedical ethics. Although disabled people and their advocates (...) have been quite vocal regarding their views on disability and in critiquing bioethicists’ approaches to issues that affect them, the interests, knowledge, and experiences of disabled people have had minimal impact on discussions within biomedical ethics textbooks. The risks of making problematic assumptions about disability are high within this subfield insofar as bioethicists impact practices within medical facilities, public policy, and, through student engagement with their texts in biomedical ethics courses, the views of potential health care professionals. All of these, in turn, affect the care provided to disabled people and potential/actual parents of disabled children. Chapter three raises ontological issues related to disability theory, examining the role of the impairment/disability distinction in framing discussions of the body as well as the status of experience. I discuss two approaches to incorporating subjective experiences of the body in disability, arguing that neither is sufficient. I examine debates within feminist theory on questions related to experience. I argue that a feminist phenomenological approach that builds on Merleau-Ponty’s work offers the best way to address bodily experiences in disability theory. The assumptions that disability theorists and Merleau-Ponty make about disability are often at odds. Chapter four points out the ableism in Merleau-Ponty’s use of a case study and considers some of the oversights within Phenomenology of Perception. In spite of my critique, I argue that his approach to phenomenology—with appropriate modifications—is useful not only for theorizing the experiences of disabled people but also for addressing other types of marginalized embodiment. Chapter five applies this method to body integrity identity disorder (BIID), arguing that combining Merleau-Ponty’s insights with those of disability theory allows us to address lived experiences of BIID and to identify assumptions about disability within research on this condition.

Germ cells are cross-roads of development and evolution. They define the origin of every new generation and, at the same time, represent the biological end-product of any mature organism. Germ cells are endowed with the following capacities: to store a self-descriptive program, to accumulate a protein-synthesizing machinery, and to incorporate enough nourishment to sustain embryonic development. To accomplish this goal, germ cells do not simply unfold a pre-determined program or realize a sole instructive role. On the contrary, due to the (...) complexity of their cytoarchitecture and the nature of the soma-to-germ interactions, they are heavily involved in processes of sign recognition and meaningful tissue exploration. At each stage of their inward migration, germ plasma membranes act as semiotic interfaces allowing cells to interact with the surrounding extracellular milieu and experience the compatibility of selected developmental sequences. The question of which signaling pathways are activated at each developmental stage does not result from a strictly predetermined program instructing germ cell stemness. Rather, each developmental sequence is an open-ended semiotic relationship explored and gradually defined during evolution by the context-dependency of specific cell-to-cell interactions. In this way, any structural and functional novelty that has emerged in the course of germ cell interactions may be interpreted as an exaptation fixed in the species genome in response to specific environmental constraints.

Biological atomism postulates that all life is composed of elementary and indivisible vital units. The activity of a living organism is thus conceived as the result of the activities and interactions of its elementary constituents, each of which individually already exhibits all the attributes proper to life. This paper surveys some of the key episodes in the history of biological atomism, and situates cell theory within this tradition. The atomistic foundations of cell theory are subsequently dissected and discussed, together with (...) the theory’s conceptual development and eventual consolidation. This paper then examines the major criticisms that have been waged against cell theory, and argues that these too can be interpreted through the prism of biological atomism as attempts to relocate the true biological atom away from the cell to a level of organization above or below it. Overall, biological atomism provides a useful perspective through which to examine the history and philosophy of cell theory, and it also opens up a new way of thinking about the epistemic decomposition of living organisms that significantly departs from the physicochemical reductionism of mechanistic biology.

Collecting, comparing, and computing molecular sequences are among the most prevalent practices in contemporary biological research. They represent a specific way of producing knowledge. This paper explores the historical development of these practices, focusing on the work of Margaret O. Dayhoff, Richard V. Eck, and Robert S. Ledley, who produced the first computer-based collection of protein sequences, published in book format in 1965 as the Atlas of Protein Sequence and Structure. While these practices are generally associated with the rise of (...) molecular evolution in the 1960s, this paper shows that they grew out of research agendas from the previous decade, including the biochemical investigation of the relations between the structures and function of proteins and the theoretical attempt to decipher the genetic code. It also shows how computers became essential for the handling and analysis of sequence data. Finally, this paper reflects on the relationships between experimenting and collecting as two distinct “ways of knowing” that were essential for the transformation of the life sciences in the twentieth century.

In the advertising discourse of human genetic database projects, of genetic ancestry tracing companies, and in popular books on anthropological genetics, what I refer to as the anthropological gene and genome appear as documents of human history, by far surpassing the written record and oral history in scope and accuracy as archives of our past. How did macromolecules become "documents of human evolutionary history"? Historically, molecular anthropology, a term introduced by Emile Zuckerkandl in 1962 to characterize the study of primate (...) phylogeny and human evolution on the molecular level, asserted its claim to the privilege of interpretation regarding hominoid, hominid, and human phylogeny and evolution vis-à-vis other historical sciences such as evolutionary biology, physical anthropology, and paleoanthropology. This process will be discussed on the basis of three key conferences on primate classification and evolution that brought together exponents of the respective fields and that were held in approximately ten-years intervals between the early 1960s and the 1980s. I show how the anthropological gene and genome gained their status as the most fundamental, clean, and direct records of historical information, and how the prioritizing of these epistemic objects was part of a complex involving the objectivity of numbers, logic, and mathematics, the objectivity of machines and instruments, and the objectivity seen to reside in the epistemic objects themselves.

We develop a new metaphor account where metaphors become surrogate variables for different but related phenomena. As we will argue, subrogation is the result of the interplay between the things inspired by the metaphor and the empirical dynamics that result from such inspiration. In particular, we focus on adaptive radiation, a major concept of evolutionary biology. Our study suggests that there is no distinct phenomenon, process, or pattern in nature than can be identified as adaptive radiation. What we have instead (...) is a grouping variable that has surrogated different evolutionary phenomena into one expansive label. We believe this analysis of metaphors helps better understand the value of metaphors for science not only as a provider of epistemic and cognitive virtues but most importantly, as a crucial research tool that can both help and divert scientific experimentation.

I reject both (a) inevitabilism about the historical development of the sciences and (b) what Ian Hacking calls the "put up or shut up" argument against those who make contingentist claims. Each position is guilty of a lack of humility about our epistemic capacities.

This essay recognizes that the interactions that define medical care are problematic and that narrative is invoked to overcome these strains. Being grounded in science, medicine, too, might be influenced by a particular world-view that arose in the natural philosophy of the Scientific Revolution. If narrative responds to this sort of medicine, it may retain traces of this mindset. A feminist approach responds to this viewpoint and may used beneficially to analyze both the story of medicine and the stories within (...) medicine. Tensions discussed from this perspective are those between sickness and health and those between patient and provider; also questioned are suitable form(s) of narrative and whose narratives are valued. Suggestions for broadening narrative to address these issues include letting the body speak for itself, overcoming the power differential in the patient/provider interaction and using standpoints to foster a more equal and just medical system.

In a recent opinion piece, Denis Duboule has claimed that the increasing shift towards systems biology is driving evolutionary and developmental biology apart, and that a true reunification of these two disciplines within the framework of evolutionary developmental biology may easily take another 100 years. He identifies methodological, epistemological, and social differences as causes for this supposed separation. Our article provides a contrasting view. We argue that Duboule’s prediction is based on a one-sided understanding of systems biology as a science (...) that is only interested in functional, not evolutionary, aspects of biological processes. Instead, we propose a research program for an evolutionary systems biology, which is based on local exploration of the configuration space in evolving developmental systems. We call this approach—which is based on reverse engineering, simulation, and mathematical analysis—the natural history of configuration space. We discuss a number of illustrative examples that demonstrate the past success of local exploration, as opposed to global mapping, in different biological contexts. We argue that this pragmatic mode of inquiry can be extended and applied to the mathematical analysis of the developmental repertoire and evolutionary potential of evolving developmental mechanisms and that evolutionary systems biology so conceived provides a pragmatic epistemological framework for the EvoDevo synthesis.

Is the gene 'special' for historians? What effects, if any, has the notion of the 'gene' had on our understanding of history? Certainly, there is a widespread public and professional perception that genetics and history are or should be in dialogue with each other in some way. But historians and geneticists view history and genetics very differently - and assume very different relationships between them. And public perceptions of genes, genetics, genomics, and indeed the nature and meanings of 'history' differ (...) yet again. Here, in looking at the meaning, and the implications - the significance - of the gene (and its corollary scientific disciplines and approaches) specifically to historians, I will focus on two aspects of the discourse. First, I will examine the ways in which historians have thus far approached genes and genetics, and the impact such studies have had on the field. There is considerable overlap between the subject matter of genetics/genomics and many of the most widely used analytic categories of contemporary historiography - race, gender, sexuality, ethnicity, (dis)ability, among others. Yet the impact of genetics and genomics on society has been studied principally by anthropologists, sociologists and ethicists.2 Only two historical sub-disciplines have engaged with the rise of genetics to any significant degree: the histories of science and of medicine. What does this indicate or suggest? Second, I will explore the impact of the 'gene' and genetic understandings (of, for example, the body, health, disease, identity, the family, and evolution) on public conceptions of history itself.

Griffiths and Stotz’s Genetics and Philosophy: An Introduction offers a very good overview of scientific and philosophical issues raised by present-day genetics. Examining, in particular, the questions of how a “gene” should be defined and what a gene does from a causal point of view, the authors explore the different domains of the life sciences in which genetics has come to play a decisive role, from Mendelian genetics to molecular genetics, behavioural genetics, and evolution. In this review, I highlight what (...) I consider as the two main theses of the book, namely: genes are better conceived as tools; genes become causes only in a context. I situate these two theses in the wider perspective of developmental systems theory. This leads me to emphasize that Griffiths and Stotz reflect very well an on going process in genetics, which I call the “epigenetization” of genetics, i.e., the growing interest in the complex processes by which gene activation is regulated. I then make a factual objection, which is that Griffiths and Stotz have almost entirely neglected the perspective of ecological developmental biology, and more precisely recent work on developmental symbioses, and I suggest that this omission is unfortunate in so far as an examination of developmental symbioses would have considerably strengthened Griffiths and Stotz’s own conclusions.

This paper argues that biological organisation can be legitimately conceived of as an intrinsically teleological causal regime. The core of the argument consists in establishing a connection between organisation and teleology through the concept of self-determination: biological organisation determines itself in the sense that the effects of its activity contribute to determine its own conditions of existence. We suggest that not any kind of circular regime realises self-determination, which should be specifically understood as self-constraint: in biological systems, in particular, self-constraint (...) takes the form of closure, i.e. a network of mutually dependent constitutive constraints. We then explore the occurrence of intrinsic teleology in the biological domain and beyond. On the one hand, the organisational account might possibly concede that supra-organismal biological systems could realise closure, and hence be teleological. On the other hand, the realisation of closure beyond the biological realm appears to be highly unlikely. In turn, the occurrence of simpler forms of self-determination remains a controversial issue, in particular with respect to the case of self-organising dissipative systems. (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

Although it may seem like a truism to assert that biology is the science that studies organisms, during the second half of the twentieth century the organism category disappeared from biological theory. Over the past decade, however, biology has begun to witness the return of the organism as a fundamental explanatory concept. There are three major causes: (a) the realization that the Modern Synthesis does not provide a fully satisfactory understanding of evolution; (b) the growing awareness of the limits of (...) reductionism in molecular biology; and (c) the renewed interest in the nature of life as a genuine scientific problem. This essay examines these recent developments and considers the new epistemological roles being played by the organism in each of them. It also reflects on what the present resurgence of the organism means for the philosophy of biology. (shrink)

David Chalmers and Frank Jackson have promoted a strong program of conceptual analysis, which accords a significant philosophical role to the a priori analysis of concepts. They found this methodological program on an account of concepts using two-dimensional semantics. This paper argues that Chalmers and Jackson’s account of concepts, and the related approach by David Braddon-Mitchell, is inadequate for natural kind concepts as found in biology. Two-dimensional semantics is metaphysically faulty as an account of the nature of concepts and concept (...) possession. It is also methodologically flawed as a guideline for how to study scientific concepts. Proponents of two-dimensional semantics are criticized for not taking seriously semantic variation between persons and for failing to adequately account for the rationality of semantic change. I suggest a more pragmatic approach to natural kind term meaning, arguing that the epistemic goal pursued by a term’s use is an additional semantic property. (shrink)

This article investigates the status of Norbert Elias’s conception of the sociology of knowledge as the means to provide a new epistemological security for sociology. The author of the article argues that this translates into an effective critique of the underlaboring model of the relationship between philosophy and the social sciences, which is consistent with Elias’s attempt to consolidate his own sociological theory. Nevertheless, the author argues that Elias’s sociology of knowledge runs into problems in its attempt to evade the (...) problem of relativism in explanation, and in its conception of human agency.

ArgumentResearch into the biological markers of pathology has long been a feature of British psychiatry. Such somatic indicators and associated features of mental disorder often intertwine with discourse on psychological and behavioral correlates and causes of mental ill-health. Disorders of sociality – particularly psychopathy and antisocial personality disorder – are important instances where the search for markers of pathology has a long history; research in this area has played an important role in shaping how mental health professionals understand the conditions. (...) Here, I characterize the multiplicity of psychiatric praxis that has sought to define the mark of antisociality as a form of “ontological anarchy.” I regard this as an essential feature of the search for biological and other markers of an unstable referent, positing that uncertainties endure – in part – precisely because of attempts to build consensus regarding the ontology of antisociality through biomedical means. Such an account is suggestive of the co-production of biomarkers, mental disorder, and psychiatric institutions. (shrink)

The term ‘vitalism’ is most readily associated with a series of debates among 18th- and 19th-century biologists, and broadly with the claim that the explanation of living phenomena is not compatible with, or is not exhausted by, the principles of basic sciences like physics and chemistry. Scientists and philosophers have continued to address vitalism - mostly in order to reject it - well into the second half of the 20th century, in connection with classic concepts such as mechanism, reductionism, emergence, (...) complexity and artificial intelligence, and in connection with approaches such as information theory and cybernetics. This article problematizes and transforms the claim that vitalism is obsolete by evaluating it diachronically, in the spirit of the historian and philosopher of medicine, Georges Canguilhem. It discusses the contrast between classical vitalism and Canguilhem’s own claim that vitalism is ‘an imperative rather than a method and more of an ethical system, perhaps, than a theory’. At the same time, it argues (against postmodern and post-humanist critics) that Canguilhem’s position cannot be reduced to a ‘polemical vitalism’ devoid of compromising references to reality or ontology. In relation to contemporary forms of engagement between social theory and biotechnoscience, Canguilhem’s vitalism continues to provide the critical corrective that is proper to its ‘vitality’.

This article explores contemporary biopolitics in the light of Michel Foucault's oft quoted suggestion that contemporary politics calls `life itself' into question. It suggests that recent developments in the life sciences, biomedicine and biotechnology can usefully be analysed along three dimensions. The first concerns logics of control - for contemporary biopolitics is risk politics. The second concerns the regime of truth in the life sciences - for contemporary biopolitics is molecular politics. The third concerns technologies of the self - for (...) contemporary biopolitics is ethopolitics. The article suggests that, in these events, human beings have become `somatic individuals': personhood is increasingly being defined in terms of corporeality, and new and direct relations are established between our biology and our conduct. At the same time, this somatic and corporeal individuality has become opened up to choice, prudence and responsibility, to experimentation, to contestation and so to a politics of `life itself'.

ArgumentWhat does “life” become at a moment when biological inquiry proceeds by manufacturing biological artifacts and systems? In this article, I juxtapose two radically different communities, synthetic biologists and Hyperbolic Crochet Coral Reef crafters (HCCR). Synthetic biology is a decade-old research initiative that seeks to merge biology with engineering and experimental research with manufacture. The HCCR is a distributed venture of three thousand craftspeople who cooperatively fabricate a series of yarn and plastic coral reefs to draw attention to the menace (...) climate change poses to the Great Barrier and other reefs. Interpreting these two groups alongside one another, I suggest that for both, manufacturing biological artifacts advances their understandings of biology: in a rhetorical loop, they build new biological things in order to understand the things they are making. The resulting fabrications condense scientific and folk theories about “life” and also undo “life” as a coherent analytic object. (shrink)

The Aristotelian axiom that function follows form was beautifully instantiated in molecular biology by the discovery of DNA’s structure that immediately suggested how DNA might work as depository and vehicle for genetic information. However, later on molecular biology became infatuated with the gene that became the center of the universe. This gene-centered viewpoint is an obstacle for the emerging field of evo-devo aiming at finding the causal connections between evolution and biological development. Here it is argued that molecular biology must (...) reject the narrow-minded causality associated with the gene-centered view and so it must recover to the spirit of Aristotelian natural history and its four types of causation in order to foster the evo-devo field of research.

Philosophical anthropologies that emphasise the role of the emotions can be used to expand existing notions of moral agency and learning in situations of great moral complexity. In this article we tell the story of one patient facing the tough decision of whether to be tested for Huntington’s disease or not. We then interpret her story from two different but compatible philosophical entry points: Aristotle’s conception of Greek tragedy and Karl Jaspers’ notion of Grenzsituationen (boundary situations). We continue by indicating (...) some ways in which these two positions may be used for reflecting upon different perspectives involved in clinical decision-making, those of patients, clinicians and bioethicists. We conclude that the ideas we introduce can be used as hermeneutic tools for situating learning and dialogue within a broader cultural field in which literature and art may also play important roles.

Recalling the title of Yoxen’s classical paper on the influence of Schrödinger’s book, I analyze the role that the work of H. Pattee might have played, if any, in the development of Biosemiotics. I take his 1969 paper “How does a molecule become a message?” (Developmental Biology Supplement) as a first target due to several circumstances that make it especially salient. On the one hand, even if Pattee has obviously developed further his ideas on later papers, the significance of this (...) one springs out right from the title, the journal and date of publication and, of course, its content. On the other, this paper in particular has been somehow rediscovered recently and not only within the frame of biosemiotics (eg, in history and philosophy of biology by E.F. Keller). Following the parallelism with Yoxen’s perspective, I contend that Pattee’s work was relatively influential with respect to a good amount of attempts to rethink living systems within theoretical biology around the 70s. This influence diminished together with the decay or even collapse of those attempts under the impact of molecular biology as it was being developed those years. Eventually, Pattee’s work has been taken up again. Notwithstanding, it is quite clear that Pattee himself was not intending to contribute specifically to Biosemiotics and that he was probably unaware of any such discipline, at least until recently. Then, we should as well ask (as Yoxen wonders with respect to Schrödinger) to which extent Pattee’s influence has been a direct one or rather an indication of the relevance of his ideas and the resonance of his hypotheses with those of biosemiotics. For this task I will sketch a few points of convergence and divergence and examine the work of some authors who either address directly this issue or have contributed significantly to build up the history of Biosemiotics.

For at least a century it has been known that multiple factors play a role in the development of complex traits, and yet the notion that there are genes “for” such traits, which traces back to Mendel, is still widespread. In this paper, we illustrate how the Mendelian model has tacitly encouraged the idea that we can explain complexity by reducing it to enumerable genes. By this approach many genes associated with simple as well as complex traits have been identified. (...) But the genetic architecture of biological traits, or how they are made, remains largely unknown. In essence, this reflects the tension between reductionism as the current “modus operandi” of science, and the emerging knowledge of the nature of complex traits. Recent interest in systems biology as a unifying approach indicates a reawakened acceptance of the complexity of complex traits, though the temptation is to replace “gene for” thinking by comparably reductionistic “network for” concepts. Both approaches implicitly mix concepts of variants and invariants in genetics. Even the basic question is unclear: what does one need to know to “understand” the genetic basis of complex traits? New operational ideas about how to deal with biological complexity are needed. (shrink)

The transcriptional profile of the entire Caulobacter crescentus genome over a synchronous cell cycle was recently described.(1) The analysis reveals a stunning 553 cell-cycle-regulated genes or orfs, nearly 19% of the genome, including putative functions in virtually all biological activities. Over a quarter of these genes/orfs respond to the Caulobacter master regulator, CtrA, most of them apparently indirectly. The analysis confirms and extends earlier observations showing that many proteins involved in cell cycle functions are expressed at the cell age when (...) they are needed. Conversely, the data suggest that proteins specifically expressed at a particular age may be involved in a process taking place then. BioEssays 23:563–565, 2001. © 2001 John Wiley & Sons, Inc.

This paper examines the discourses and practices of pedigree livestock breeding, focusing on beef cattle and sheep in the UK, concentrating on an under-examined aspect of this—the deselection and rejection of some animals from future breeding populations. In the context of exploring how animals are valued and represented in different ways in relation to particular agricultural knowledge-practices, it focuses on deselecting particular animals from breeding populations, drawing attention to shifts in such knowledge-practices related to the emergence of “genetic” techniques in (...) livestock breeding which are arguably displacing “traditional” visual and experiential knowledge’s of livestock animals. The paper situates this discussion in the analytical framework provided by Foucault’s conception of “biopower,” exploring how interventions in livestock populations aimed at the fostering of domestic animal life are necessarily also associated with the imperative that certain animals must die and not contribute to the future reproduction of their breed. The “geneticization” of livestock breeding produces new articulations of this process associated with different understandings of animal life and the possibilities of different modes of intervention in livestock populations. Genetic techniques increasingly quantify and rationalize processes of selection and deselection, and affect how animals are perceived and valued both as groups and as individuals. The paper concludes by emphasizing that the valuation of livestock animals is contested, and that the entanglement of “traditional” and “genetic” modes of valuation means that there are multiple layers of valuation and (de)selection involved in breeding knowledge-practices.

The writings of Joseph Henry Woodger (1894–1981) are often taken to exemplify everything that was wrongheaded, misguided, and just plain wrong with early twentieth-century philosophy of biology. Over the years, commentators have said of Woodger: (a) that he was a fervent logical empiricist who tried to impose the explanatory gold standards of physics onto biology, (b) that his philosophical work was completely disconnected from biological science, (c) that he possessed no scientific or philosophical credentials, and (d) that his work was (...) disparaged – if not altogether ignored – by the biologists and philosophers of his era. In this paper, we provide the first systematic examination of Woodger’s oeuvre, and use it to demonstrate that the four preceding claims are false. We argue that Woodger’s ideas have exerted an important influence on biology and philosophy, and submit that the current consensus on his legacy stems from a highly selective reading of his works. By rehabilitating Woodger, we hope to show that there is no good reason to continue to disregard the numerous contributions to the philosophy of biology produced in the decades prior to the professionalization of the discipline.

Physics and chemistry underlie the nature of all the world around us, including human brains. Consequently some suggest that in causal terms, physics is all there is. However, we live in an environment dominated by objects embodying the outcomes of intentional design (buildings, computers, teaspoons). The present day subject of physics has nothing to say about the intentionality resulting in existence of such objects, even though this intentionality is clearly causally effective. This paper examines the claim that the underlying physics (...) uniquely causally determines what happens, even though we cannot predict the outcome. It suggests that what occurs is the contextual emergence of complexity: the higher levels in the hierarchy of complexity have autonomous causal powers, functionally independent of lower level processes. This is possible because top-down causation takes place as well as bottom-up action, with higher level contexts determining the outcome of lower level functioning and even modifying the nature of lower level constituents. Stored information plays a key role, resulting in non-linear dynamics that is non-local in space and time. Brain functioning is causally affected by abstractions such as the value of money and the theory of the laser. These are realised as brain states in individuals, but are not equivalent to them. Consequently physics per se cannot causally determine the outcome of human creativity, rather it creates the possibility space allowing human intelligence to function autonomously. The challenge to physics is to develop a realistic description of causality in truly complex hierarchical structures, with top-down causation and memory effects allowing autonomous higher levels of order to emerge with genuine causal powers.

I argue that Darwinian evolutionary theory has a rhetorical dimension and that rhetorical criticism plays a role in how evolutionary science acquires knowledge. I define what I mean by rhetoric by considering Darwin’s Origin. I use the Modern Evolutionary Synthesis to show how rhetoric conceived as situated and addressed argumentation enters into evolutionary theorizing. Finally, I argue that rhetorical criticism helps judge the success, limits, and failures of these theories.

While scientific terms lack the stability of physical objects, they are generally far more stable than the various meanings associated with them. As a consequence, they tend to carry older conceptions alongside those more recently acquired, thereby exerting an effective drag against conceptual change. I illustrate this claim with an analysis of the shifting meanings of the term genome, originally used to refer to a collectivity of genes, but more recently to an organism’s complement of DNA. While genes were originally (...) regarded as effectively autonomous formal agents, and DNA as collections of genes, contemporary research suggests that an organism’s DNA constitutes a far more complex system designed to adapt and respond to the environment in which it finds itself.

We trace the history of the Modern Evolutionary Synthesis, and of genetic Darwinism generally, with a view to showing why, even in its current versions, it can no longer serve as a general framework for evolutionary theory. The main reason is empirical. Genetical Darwinism cannot accommodate the role of development (and of genes in development) in many evolutionary processes. We go on to discuss two conceptual issues: whether natural selection can be the “creative factor” in a new, more general framework (...) for evolutionary theorizing; and whether in such a framework organisms must be conceived as self-organizing systems embedded in self-organizing ecological systems.

No comprehensive theory of development is available yet. Traditionally, we regard the development of animals as a sequence of changes through which an adult multicellular animal is produced, starting from a single cell which is usually a fertilized egg, through increasingly complex stages. However, many phenomena that would not qualify as developmental according to these criteria would nevertheless qualify as developmental in that they imply nontrivial (e.g., non degenerative) changes of form, and/or substantial changes in gene expression. A broad, comparative (...) approach is badly needed. In the Cnidaria, for example, even the boundary between generations is problematic. Describing their life cycle in terms of metagenesis (alternation between polyp generation and medusa generation) or in terms of metamorphosis (polyp as larva or juvenile) are matters of semantics more than biology. The life cycle of other metazoans, described in textbooks in terms of larva-to-adult metamorphosis, is hardly different from a typical metagenetic life cycle of cnidarians. This applies to holometabolous insects and to marine invertebrates like sea urchins, where most of the larval cells are discarded at metamorphosis. The uncertain temporal and spatial boundaries of individual development are also shown by the widespread lack of a strict correspondence between adult and mature. A comprehensive theory of development should start with a zero principle of “developmental inertia,” corresponding to an indeterminate local self-perpetuation of cell-level dynamics. Indeterminate growth, scale-invariance, segmentation, and regeneration provide examples of developmental dynamics close to that. (shrink)

This paper argues for a broader understanding of complexity; an understanding that speaks to the multidimensionality of environmental problems. As argued, environmental problems rest upon ontological, epistemological, and moral claims; they rest, in other words, upon statements about what is, knowledge, and what ought to be, respectively. To develop and illustrate this argument, the GMO (genetically modified organism) controversy is broken down according to these three dimensions. Dissecting environmental problems in this manner reveals why we cannot look solely toward the (...) natural sciences for resolution: because these problems beg questions that cannot be answered with references to materiality alone.

A number of areas of biology raise questions about what is of value in the natural environment and how we ought to behave towards it: conservation biology, environmental science, and ecology, to name a few. Based on my experience teaching students from these and similar majors, I argue that the field of environmental ethics has much to teach these students. They come to me with pent-up questions and a feeling that more is needed to fully engage in their subjects, and (...) I believe some exposure to environmental ethics can help focus their interests and goals. I identify three primary areas in which environmental ethics can con- tribute to their education. The first is an examination of who (or what) should be considered to be part of our moral community (i.e., the community to whom we owe direct duties). Is it humans only? Or does it include all sentient life? Or all life? Or ecosystems considered holistically? Often, readings implicitly assume one or more of these answers; the goal is to make the student more sensitive to these implicit claims and to get them to think about the different reasons that support them. The second area, related to the first, is the application of the different answers concerning the extent of the ethical community to real environmental issues and problems. Students need to be aware of how the different answers concerning the moral community can imply conflicting answers for how we should act in certain cases and to think about ways to move toward conflict resolution. The third area in which environmental ethics can contribute is a more conceptual one, focusing on central concepts such as biodiversity, sustainability, species, and ecosystems. Exploring and evaluating various meanings of these terms will make students more reflective and thoughtful citizens and biologists, sensitive to the implications that different conceptual choices make.

First the ‘Weismann barrier’ and later on Francis Crick’s ‘central dogma’ of molecular biology nourished the gene-centric paradigm of life, i.e., the conception of the gene/genome as a ‘central source’ from which hereditary specificity unidirectionally flows or radiates into cellular biochemistry and development. Today, due to advances in molecular genetics and epigenetics, such as the discovery of complex post-genomic and epigenetic processes in which genes are causally integrated, many theorists argue that a gene-centric conception of the organism has become problematic. (...) Here, we first explore the causal implications of the following two central dogma-related issues: (1) widespread reverse transcription—arguing for an extension from ‘DNA-genome’ to RNA-encompassing ‘NA-genome’ and, thus, from traditional DNA-centrism to a broader ‘NA-centrism’; and (2) the absence of a mechanism of reverse translation—arguing for the ‘structural primacy’ of NA-sequence over protein in cellular biochemistry. Secondly, we explore whether this latter conclusion can be extended to a ‘functional primacy’ of NA-sequence over protein in cellular biochemistry, which would imply a limited kind of ‘gene/NA-centrism’ confined to the subcellular level of NA/protein-based biochemistry. Finally, we explore the conditions—and their (non)fulfilment—for a more generalised form of gene-centrism extendable to higher levels of biological organisation. We conclude that the higher we go in the biological hierarchy, the more dubious gene-centric claims become. (shrink)

In this paper I use a case study—the discovery of the chaperon function exerted by proteins in the various steps of the hereditary process—to re-discuss the question whether the nucleic acids are the sole repositories of relevant information as assumed in the information theory of heredity. The evidence I here present of a crucial role for molecular chaperones in the folding of nascent proteins, as well as in DNA duplication, RNA folding and gene control, suggests that the family of proteins (...) acting as molecular chaperones provides information that is complementary to that stored in the nucleic acids, and equally important. A re-evaluation of the role of proteins in the hereditary process is in order away from the gene-centric approach of the information theory of heredity, to which neo-Darwinian evolutionists adhere.

In 2002, Evolution and Human Behavior published a study purporting to show that the differences in toy preferences commonly attributed to girls and boys can also be found in male and female vervet monkeys, tracing the origin of these differing preferences back to a common ancestor. Despite some flaws in its design and the prima facie implausibility of some of its central claims, this research received considerable attention in both scientific circles and the popular media. In what follows, I survey (...) some of the problems with this study that seem to be characteristic of research into sex differences in a particular research program in evolutionary psychology. I suggest that an epistemology of ignorance is at work that suppresses the methods and insights of an earlier research program, which emphasized the complexity and contingency that ultimately grounds the variety of human behaviors, in favor of one that has been widely criticized as empirically flawed and politically pernicious. I conclude with some speculative remarks on the persistence of this problematic research program in evolutionary psychology. (shrink)

According to vitalism, living organisms differ from machines and all other inanimate objects by being endowed with an indwelling immaterial directive agency, ‘vital force,’ or entelechy . While support for vitalism fell away in the late nineteenth century many biologists in the early twentieth century embraced a non vitalist philosophy variously termed organicism/holism/emergentism which aimed at replacing the actions of an immaterial spirit with what was seen as an equivalent but perfectly natural agency—the emergent autonomous activity of the whole organism. (...) Organicists hold that organisms unlike machines are ‘more than the sum of their parts’ and predict that the vital properties of living things can never be explained in terms of mechanical analogies and that the reductionist agenda is doomed to failure. Here we review the current status of the mechanist and organicist conceptions of life particularly as they apply to the cell. We argue that despite the advances in biological knowledge over the past six decades since the molecular biological revolution, especially in the fields of genetics and cell biology the unique properties of living cells have still not been simulated in mechanical systems nor yielded to reductionist—analytical explanations. And we conclude that despite the dominance of the mechanistic–reductionist paradigm through most of the past century the possibility of a twentyfirst century organicist revival cannot be easily discounted.

Historians of molecular biology have paid significant attention to the role of scientific instruments and their relationship to the production of biological knowledge. For instance, Lily Kay has examined the history of electrophoresis, Boelie Elzen has analyzed the development of the ultracentrifuge as an enabling technology for molecular biology, and Nicolas Rasmussen has examined how molecular biology was transformed by the introduction of the electron microscope (Kay 1998, 1993; Elzen 1986; Rasmussen 1997). 1 Collectively, these historians have demonstrated how instruments (...) and other elements of the material culture of the laboratory have played a decisive role in determining the kind and quantity of ..

This article offers the critical concept misfit in an effort to further think through the lived identity and experience of disability as it is situated in place and time. The idea of a misfit and the situation of misfitting that I offer here elaborate a materialist feminist understanding of disability by extending a consideration of how the particularities of embodiment interact with the environment in its broadest sense, to include both its spatial and temporal aspects. The interrelated dynamics of fitting (...) and misfitting constitute a particular aspect of world-making involved in material-discursive becoming. The essay makes three arguments: the concept of misfit emphasizes the particularity of varying lived embodiments and avoids a theoretical generic disabled body; the concept of misfit clarifies the current feminist critical conversation about universal vulnerability and dependence; the concept of misfitting as a shifting spatial and perpetually temporal relationship confers agency and value on disabled subjects.

In this paper we will argue: (1) that scholars, regardless of their normative stand against or for genetic enhancement indeed have a moral/professional obligation to hold on to a realistic and up-to-date conception of genetic enhancement; (2) that there is an unwarranted hype surrounding the issue of genetic enhancement in general, and gene doping in particular; and (3) that this hype is, at least partly, created due to a simplistic and reductionist conception of genetics often adopted by bioethicists.
