This essay considers how scholarly approaches to the development of molecular biology have too often narrowed the historical aperture to genes, overlooking the ways in which other objects and processes contributed to the molecularization of life. From structural and dynamic studies of biomolecules to cellular membranes and organelles to metabolism and nutrition, new work by historians, philosophers, and STS scholars of the life sciences has revitalized older issues, such as the relationship of life to matter, or of physicochemical inquiries to (...) biology. This scholarship points to a novel molecular vista that opens up a pluralist view of molecularizations in the twentieth century and considers their relevance to current science. (shrink)

The term ‘cell’, in addition to designating fundamental units of life, has also been applied since the nineteenth century to technical apparatuses such as fuel and galvanic cells. This paper shows that such technologies, based on the electrical effects of chemical reactions taking place in containers, had a far-reaching impact on the concept of the biological cell. My argument revolves around the controversy over oxidative phosphorylation in bioenergetics between 1961 and 1977. In this scientific conflict, a two-level mingling of technological (...) culture, physical chemistry and biological research can be observed. First, Peter Mitchell explained the chemiosmotic hypothesis of energy generation by representing cellular membrane processes via an analogy to fuel cells. Second, in the associated experimental scrutiny of membranes, material cell models were devised that reassembled spatialized molecular processes in vitro. Cells were thus modelled both on paper and in the test tube not as morphological structures but as compartments able to perform physicochemical work. The story of cells and membranes in bioenergetics points out the role that theories and practices in physical chemistry had in the molecularization of life. These approaches model the cell as a ‘topology of molecular action’, as I will call it, and it involves concepts of spaces, surfaces and movements. They epitomize an engineer’s vision of the organism that has influenced diverse fields in today’s life sciences. (shrink)

We invite systematic consideration of the metaphors of cycles and circulation as a long-term theme in the history of the life and environmental sciences and medicine. Ubiquitous in ancient religious and philosophical traditions, especially in representing the seasons and the motions of celestial bodies, circles once symbolized perfection. Over the centuries cyclic images in western medicine, natural philosophy, natural history and eventually biology gained independence from cosmology and theology and came to depend less on strictly circular forms. As potent ‘canonical (...) icons’, cycles also interacted with representations of linear and irreversible change, including arrows, arcs, scales, series and trees, as in theories of the Earth and of evolution. In modern times life cycles and reproductive cycles have often been held to characterize life, in some cases especially female life, while human efforts selectively to foster and disrupt these cycles have harnessed their productivity in medicine and agriculture. But strong cyclic metaphors have continued to link physiology and climatology, medicine and economics, and biology and manufacturing, notably through the relations between land, food and population. From the grand nineteenth-century transformations of matter to systems ecology, the circulation of molecules through organic and inorganic compartments has posed the problem of maintaining identity in the face of flux and highlights the seductive ability of cyclic schemes to imply closure where no original state was in fact restored. More concerted attention to cycles and circulation will enrich analyses of the power of metaphors to naturalize understandings of life and their shaping by practical interests and political imaginations.

In the context of 1960s research on biological membranes, scientists stumbled upon a curiously coloured material substance, which became called the “purple membrane.” Interactions with the material as well as chemical analyses led to the conclusion that the microbial membrane contained a photoactive molecule similar to rhodopsin, the light receptor of animals’ retinae. Until 1975, the find led to the formation of novel objects in science, and subsequently to the development of a field in the molecular life sciences that comprised (...) biophysics, bioenergetics as well as membrane and structural biology. Furthermore, the purple membrane and bacteriorhodopsin, as the photoactive membrane transport protein was baptized, inspired attempts at hybrid bio-optical engineering throughout the 1980s. A central motif of the research field was the identification of a functional biological structure, such as a membrane, with a reactive material substance that could be easily prepared and manipulated. Building on this premise, early purple membrane research will be taken as a case in point to understand the appearance and transformation of objects in science through work with material substances. Here, the role played by a perceptible material and its spontaneous change of colour, or reactivity, casts a different light on objects and experimental practices in the late twentieth century molecular life sciences. With respect to the impact of chemical working and thinking, the purple membrane and rhodopsins represent an influential domain straddling the life and chemical sciences as well as bio- and material technologies, which has received only little historical and philosophical attention. Re-drawing the boundary between the living and the non-enlivened, these researches explain and model organismic activity through the reactivity of macromolecular structures, and thus palpable material substances.

Microbial diversity has become a leitmotiv of contemporary microbiology, as epitomized in the concept of the microbiome, with significant consequences for the classification of microbes. In this paper, I contrast microbiology’s current diversity ideal with its influential predecessor in the twentieth century, that of purity, as epitomized in Robert Koch’s bacteriological culture methods. Purity and diversity, the two polar opposites with regard to making sense of the microbial world, have been operationalized in microbiological practice by tools such as the “clean” (...) Petri dish versus the “dirty” Winogradsky column, the latter a container that mimics, in the laboratory, the natural environment that teems with diverse microbial life. By tracing the impact of the practices and concepts of purity and diversity on microbial classification through a history of techniques, tools, and manuals, I show the shifts in these concepts over the last century. Juxtaposing the dominant purity ideal with the more restricted, but continuously articulated, diversity ideal in microbial ecology not only provides a fresh perspective on microbial classification that goes beyond its intellectual history, but also contextualizes the present focus on diversity. By covering the period of a century, this paper outlines a revised longue durée historiography that takes its inspiration from artifacts, such as Petri dish and the Winogradsky column, and thereby simple, but influential technologies that often remain invisible. This enables the problem of historical continuity in modern science to be addressed and the accelerationist narratives of its development to be countered. (shrink)

Laboratory manuals, notebooks and instrumentation from Otto Warburg’s Institute of Cell Physiology have been discovered at the Max Planck Institute of Biochemistry. Following Warburg’s death in 1970 one of his technicians was transferred from Berlin-Dahlem to the newly founded biochemical institute at Martinsried near Munich, and brought with him these resources, which epitomize the singular position of Warburg’s work style and institute in the 1950s and 1960s. Since the technician’s skills and apparently outmoded instrumentation like the Warburg apparatus were still (...) used in the context of 1970s membrane biochemistry, this trove also documents an unexpected continuity of research within the life sciences. Moreover, the service of Warburg’s technician, which spans more than four decades, as well as the meticulous documentation of preparations and experiments, serve as a case in point for the importance of routine and rather mundane techniques in the post-war molecular life sciences.

Subject of the Moment, Reloaded. The catalogue of Ludwig Darmstaedter's document collection, which contains sources as well as a categorization conspicuous of a history of knowledge avant la lettre, invites for a revisiting of the history of our discipline, thereby asking for its current role in academia and beyond. We argue that as historians of science or as historians of knowledge, our discipline disposes of the tools and topics necessary to respond to urgent epistemic and political problems.

The so-called.Karlsschulrede. (1793) of the German naturalist Carl Friedrich Kielmeyer can be considered as a keystone to the understanding of"Naturphilosophie" both in German idealism (Schelling) and the romantic period.Kielmeyer's work considers life as the result of specific forces in the organic realm and thereby searches to explain the harmony of organic existence anddevelopment. Taking into account Kant.s outlines for a lifescience in the "Kritik der Urteilskraft" (1790), Kielmeyer's notion of teleological processes in nature is sketched. The historical and epistemological relevance (...) of this "vital-materialistic" (Lenoir) theory of life can be characterized by three major transformations in the understanding of nature in the "Karlsschulrede": First, the development of a holistic, organological view on the world, second, the emphasis on phenomena of life as historical processes and third the analogy between organism and mind. These issues found the strong influence of Kielmeyer's text on philosophy and science in the early 19th-century. (shrink)

The first section of this issue brings together four essays on “surfaces” – a subject matter which might seem conspicuous or, indeed, palpable enough. Just think of the sheets of paper, window panes, and haptic interfaces surrounding you: the world, evidently, is diffused with surfaces, membranes, and boundaries of all sorts. Some of these things have been salient, for obvious reasons in fields such as media studies, or implicit in notions such as “boundary object”: the retina, photographic plates, basilar membranes, (...) the skin, or various forms of “displays” immediately come to mind. Not even mentioning their immense metaphoricity, surfaces are the entities that make things visible, inscribable, or knowable. But not all of them have been so salient. In fact, most surface-phenomena arguably – and, typically, for similarly obvious reasons – haven't received much scholarly notice at all: plastic wraps, lacquers, lubricants, coatings, silicon wavers, cell membranes, glass, plant leaves, the ozone layer.

David Albert and Barry Loewer have argued that the temporal asymmetry of our concept of causal influence or control is grounded in the statistical mechanical assumption of a low-entropy past. In this paper I critically examine Albert's and Loewer 's accounts.

Ist Leben mehr als eine Leistung „natürlicher Systeme“? Wie unterscheiden sich Lebewesen von Artefakten? Lassen sich Lebewesen genauso herstellen wie Maschinen? Diese Fragen werden mit dem Siegeszug der „converging technologies“ besonders dringlich, denn je mehr Biologie, Ingenieurswissenschaften, Informatik und Physik zusammenfinden, desto weniger scheinen gewohnte Unterscheidungen zu treffen. Doch zeigt eine systematische Rekonstruktion der Lebenswissenschaften in ihrer aktuellen Form als Systembiologie und synthetische Biologie, daß es sich dabei um ein Selbstmissverständnis der Logik wissenschaftlicher Darstellung handelt. Eine alternative Auffassung der begrifflichen (...) Struktur unserer Rede über Lebendiges ist Anliegen dieses Buches. Leben ist danach eine Formbestimmung von Tätigkeitsverhältnissen, die sowohl theoretische wie praktische Begründungen ermöglicht. Die Entfaltung der spezifisch technischen Form dieses Wissens über das Lebendige gestattet es nicht nur, szientistische Verkürzungen zu vermeiden, sondern zudem den methodischen Ort wissenschaftlicher Strukturierungen von Lebendigem auszuzeichnen. Auf dieser Grundlage wird schließlich auch „der Menschen“ durch Lebenswissenschaften darstellbar – und zwar so, wie es der historischen Form des Gegenstandes angemessen ist. (shrink)

Best known for his influential History of Greece, the historian and politician George Grote wrote this account of Plato's dialogues as a philosophical supplement to the History. First published in 1865 and written in dialogic form, Grote's account of Plato's works includes substantial footnotes and marginalia. This first volume focuses on Plato's early and transitional dialogues, all of which feature Socrates. It also includes a preface to the whole project which discusses the meaning and importance of philosophy itself, (...) and extensive introductory material on pre-Socratic philosophy, the life of Plato and history of the Platonic canon. With three volumes each running to over six hundred pages, Grote's scholarship is formidably comprehensive. The publication of Plato and the Other Companions of Sokrates confirmed him as one of the greatest authorities on Plato in the nineteenth century. (shrink)

Issues of reliability are claiming center-stage in the epistemology of machine learning.

Priority setting in health care is ubiquitous and health authorities are increasingly recognising the need for priority setting guidelines to ensure efficient, fair, and equitable resource allocation. While cost-effectiveness concerns seem to dominate many policies, the tension between utilitarian and deontological concerns is salient to many, and various severity criteria appear to fill this gap. Severity, then, must be subjected to rigorous ethical and philosophical analysis. Here we first give a brief history of the path to today’s severity criteria in (...) Norway and Sweden. The Scandinavian perspective on severity might be conducive to the international discussion, given its long-standing use as a priority setting criterion, despite having reached rather different conclusions so far. We then argue that severity can be viewed as a multidimensional concept, drawing on accounts of need, urgency, fairness, duty to save lives, and human dignity. Such concerns will often be relative to local mores, and the weighting placed on the various dimensions cannot be expected to be fixed. Thirdly, we present what we think are the most pertinent questions to answer about severity in order to facilitate decision making in the coming years of increased scarcity, and to further the understanding of underlying assumptions and values that go into these decisions. We conclude that severity is poorly understood, and that the topic needs substantial further inquiry; thus we hope this article may set a challenging and important research agenda. (shrink)

English summary: The present work demonstrates the important influence of Heidegger on the philosophical thought of Walter Benjamin, on his philosophy of history, as well as his philosophy of art and language. Concentrating on the formative periods for both philosophers, the work examines their early education, as well as the interlacing of the philosophy of art and history in their concept of art. The final section treats works by both philosophers on the philosophy of art from their early years. French (...) description: L'objectif principal de ce livre est de demontrer de quelle maniere la lecture de certains textes de jeunesse de Heidegger marqua profondement la pensee philosophique de Benjamin. Celui-ci aurait subi l'influence heideggerienne aussi bien au niveau de sa propre philosophie de l'histoire que de sa philosophie du langage et de sa philosophie de l'art. Le fondement theorique est l'approche de la periode de formation, encore peu etudiee, des deux philosophes. La philosophie neokantienne est le principal courant philosophique a l'epoque dans toutes les universites allemandes. C'est pourquoi le point de depart de la recherche, notamment pour la premiere et la deuxieme partie (histoire et langage), se centre sur la formation des jeunes Benjamin et Heidegger aupres de maitres tels que Heinrich Rickert, Edmund Husserl et Emil Lask. L'entrecroisement de philosophie de l'histoire et de philosophie du langage aura une projection decisive dans le debat concernant le concept d'art chez les deux philosophes. Le troisieme axe d'etude porte quant a lui sur la philosophie de l'art. Il traite du livre de Heidegger date de 1929 sur Kant et le probleme de la metaphysique, et du texte de jeunesse de Benjamin intitule L'arc-en-ciel. Entretien sur l'imagination (1915). (shrink)

Dans cet ouvrage, l'auteur se livre à une comparaison conceptuelle entre le principe de précaution et le principe responsabilité. Il combat la démarche tendancieuse des penseurs de la précaution qui, à l'image de Corinne Lepage, dont la conception a été reprise par le chef de l'Etat français lors du " Grenelle de l'Environnement ", assimilent précaution et responsabilité, réduisant la seconde à la première. Précaution et responsabilité ne sont en réalité absolument pas réductibles, et le principe responsabilité tel que défini (...) par Hans Jonas contient les germes d'une remise en question du mode de développement occidental, dont la notion de développement durable est actuellement le fer de lance, que le principe de précaution ne permet pas - et qu'il interdit même. Politique de Cassandre dévoile ainsi l'escroquerie politico-intellectuelle dont le principe de précaution est la manifestation, et dont le " Grenelle de l'environnement " est le dernier avatar. La responsabilité politique ne consiste à intervenir ni en aval de la catastrophe comme nous y oblige le développement techno-scientifique, ni en amont de la catastrophe et en aval des causes de cette catastrophe comme nous y incite le principe de précaution, mais en amont des causes de la catastrophe. Cet essai, à la fois philosophique, politique et poétique, tente d'allier la rigueur de la démarche intellectuelle, le souci moral de la pratique et la sensibilité humaine. (shrink)

Literary Materialisms addresses what has become a fundamental concern in the last decade: how do we today define literary studies as an academic discipline and literature as a relevant object of study? Avoiding unproductive proclamations, this volume unites new materialist critical thinking with a commitment to fundamental principles.

Phillips argues that blindsight is due to response criterion artefacts under degraded conscious vision. His view provides alternative explanations for some studies, but may not work well when one considers several key findings in conjunction. Empirically, not all criterion effects are decidedly non-perceptual. Awareness is not completely abolished for some stimuli, in some patients. But in other cases, it was clearly impaired relative to the corresponding visual sensitivity. This relative dissociation is what makes blindsight so important and interesting.

The Internet is used for every conceivable form of communication and it is therefore only natural that it should be used as an infrastructure even for protest and civil disobedience. The technology however brings with it the ability to carry out new forms of protest, in new environments and also involve changed consequences for those involved. This article looks at four criminal activities, which are used as active forms of Internet based protest in use today and analysis these forms in (...) relation to the traditional civil disobedience discourse. The analysis is done by studying four basic criteria (disobedience, civil, non‐violence and justification) found in tradition civil disobedience discourse and observing their applicability in online environments. The purpose of this article is to better understand the political protest activities carried out online and to see whether traditional civil disobedience theory embraces these new forms of political activism.

James a maintes fois célébré les rencontres philosophiques et l’on sait les efforts de James et de Bergson pour se voir, lors des passages de James en Europe. Proximité physique ne signifie évidemment pas convergence ni capillarité philosophiques, comme l’apprend à ses dépens Agathon dans le Banquet de Platon. Or, le rapprochement, mais aussi les confusions, entre la philosophie de Bergson et celle de James, voire entre « bergsonisme » et « pragmatisme », restent un passage obligé de l’étude des (...) deux hommes. Si cette confusion — peut-être ces familles de confusions — sont caractéristiques du début du XXe siècle , il serait sans doute illusoire de croire que nous en sommes sortis aujourd’hui. C’est en France une expérience encore très répandue chez le jamesien que devoir se justifier par rapport au « bergsonisme », et c’en est une autre pour le « bergsonien » que de devoir dire qu’il n’est pas forcément « pragmatiste ». Ces glissements ont déjà été maintes fois analysés et je tiendrai ici pour acquis que Horace Kallen , Floris Delattre , Ralph Barton Perry et Millic Capek , qui ont procédé à la revue de détail, nous ont donné suffisamment d’éléments pour qu’il ne soit pas nécessaire de reprendre le dossier dans son ensemble. Le propos sera plutôt de décomposer un travers de lecture que l’on inflige généralement aux deux auteurs à partir d’un terrain plus limité : le thème du « courant », ou flux (stream), de conscience, thème prétendument commun aux deux hommes. Je vais pour cela tenter d’identifier, dans la première section, deux grandes manières d’aborder le rapport entre les deux hommes qui ont conduit à méconnaître leur apport propre. L’une interdit tout simplement de les lire comme philosophes, même si elle est couramment pratiquée, ce que j’illustrerai à la lumière de deux exemples. L’autre type de lecture engage, lui, un contresens sur la thèse même de James, et c’est ici que la face critique de ce chapitre se retourne en argument positif. Le cœur de ce contresens est de croire que James aurait introduit le thème du courant de pensée ou de conscience, et que ce serait là son originalité. Or, comme il est normal chez un auteur pragmatiste après tout, l’originalité réside dans l’usage qui est fait de ce thème. En examinant dans la deuxième section les rouages de ce contresens, dont il n’est pas certain que tous les lecteurs de Bergson l’aient totalement évité alors même qu’ils pensaient le déposer, on tentera donc de préciser tout d’abord en quoi le thème lui-même n’est pas spécifiquement jamesien, ensuite en quoi le propos de James n’est pas tant de décrire ce flux pour lui-même que de nous expliquer ce qui nous guette si nous le négligeons systématiquement, enfin quelles sont les fonctions remplies par les passages sur le courant de conscience dans l’argument de James.

Poly(ADP‐ribosyl)ation is a post‐translational modification occurring in the nucleus. The most abundant and best‐characterized enzyme catalyzing this reaction, poly(ADP‐ribose) polymerase 1 (PARP1), participates in fundamental nuclear events. The enzyme functions as molecular “nick sensor”. It binds with high affinity to DNA single‐strand breaks resulting in the initiation of its catalytic activity. Activated PARP1 promotes base excision repair. In addition, PARP1 modifies several transcription factors and thereby precludes their binding to DNA. We propose that a major function of PARP1 includes the (...) silencing of transcription preventing expression of damaged genes. Concomitant stimulation of DNA repair suggests that PARP1 acts as a switch between transcription and DNA repair. Another PARP‐type enzyme, tankyrase, is involved in the regulation of telomere elongation. Tankyrase modifies a telomere‐associated protein and thereby prevents it masking telomeric repeats providing access of telomerase for telomere elongation. Therefore, poly(ADP‐ribosyl)ation reactions may act as molecular switches in DNA metabolism. BioEssays 23:543–548, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

This essay reconstructs the place of utopia in realist political theory, by examining the ways in which the literary genre of critical utopias can productively unsettle ongoing discussions about “how to do political theory.” I start by analyzing two prominent accounts of the relationship between realism and utopia: “real utopia” and “dystopic liberalism”. Elaborating on Raymond Geuss’s recent reflections, the essay then claims that an engagement with literature can shift the focus of these accounts. Utopian fiction, I maintain, is useful (...) for comprehending what is and for contemplating what might be. Ursula K. Le Guin’s novel The Dispossessed deploys this double function in an exemplary fashion: through her dynamic and open-ended portrayal of an Anarchist community, Le Guin succeeds in imagining a utopia that negates the status quo, without striving to construct a perfect society. The book’s radical, yet ambiguous, narrative hence reveals a strategy for locating utopia within realist political theory that moves beyond the positions dominating the current debate. Reading The Dispossessed ultimately demonstrates that realism without utopia is status quo–affirming, while utopia without realism is wishful thinking. (shrink)

The associative theory of creativity states that creativity is associated with differences in the structure of semantic memory, whereas the executive theory of creativity emphasises the role of top-down control for creative thought. For a powerful test of these accounts, individual semantic memory structure was modelled with a novel method based on semantic relatedness judgements and different criteria for network filtering were compared. The executive account was supported by a correlation between creative ability and broad retrieval ability. The associative account (...) was independently supported, when network filtering was based on a relatedness threshold, but not when it was based on a fixed edge number or on the analysis of weighted networks. In the former case, creative ability was associated with shorter average path lengths and higher clustering of the network, suggesting that the semantic networks of creative people show higher small-worldness.

After a wave of breakthroughs in image‐based medical diagnostics and risk prediction models, machine learning (ML) has turned into a normal science. However, prominent researchers are claiming that another paradigm shift in medical ML is imminent—due to most recent staggering successes of large language models—from single‐purpose applications toward generalist models, driven by natural language. This article investigates the implications of this paradigm shift for the ethical debate. Focusing on issues like trust, transparency, threats of patient autonomy, responsibility issues in the (...) collaboration of clinicians and ML models, fairness, and privacy, it will be argued that the main problems will be continuous with the current debate. However, due to functioning of large language models, the complexity of all these problems increases. In addition, the article discusses some profound challenges for the clinical evaluation of large language models and threats to the reproducibility and replicability of studies about large language models in medicine due to corporate interests.

This article highlights the continuing relevance of a classic bioethical text, “Bioethics as a Discipline,” published by the Hastings Center’s cofounder Daniel Callahan in 1973. Connecting the text’s programmatic recommendations with later reflections and interventions Callahan wrote about the development of bioethics illuminates how the vision Callahan established and the reality this vision helped create were interrelated—just not in the way Callahan had hoped for. Although this portrait relies on an individual perception of the development of bioethics, it might nevertheless, (...) through its unique linkage of different bioethical temporalities, contribute to a broader reassessment of what bioethics became and why.

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate describing lists of objects. The confederate’s utterances (to which participants responded) were pre‐recorded and varied in whether they ended in a verb or an object noun and whether this (...) ending was predictable or not. We found that response planning in overlap with sentence‐final verbs evokes larger task‐evoked pupillary responses, while end predictability had no effect. This finding indicates that planning in overlap leads to higher processing load for next speakers in dialog and that next speakers do not proactively modulate the time course of their response planning based on their predictions of turn endings. The turn‐taking system exerts pressure on the language processing system by pushing speakers to plan in overlap despite the ensuing increase in processing load. (shrink)

Taking a medieval approach in content as well as in form—a compilation of lists—this volume creates a foundation for the study of the medieval mindset by establishing the terms and concepts that scholars would have had in a common at the time: an invaluable lingua franca.
