The role of fixed charges present at the surface of biological membranes is usually described by the Gouy-Chapman-Grahame theory of the electric double-layer where the Grahame equation is applied independently on each side of the membrane and where the capacitive charges are disregarded. In this article, we generalize the Gouy-Chapman-Grahame theory by taking into account both intrinsic charges and capacitive charges, in the density value of the membrane surface charges. In the first part, we show that capacitive charges couple electrostatic (...) potentials present on both sides of the membrane. The intensity of this coupling depends both on the value of the membrane specific capacitance and the transmembrane electric potential difference. In the second part, we suggest some physiological implications of membrane electric double-layers. (shrink)

A new translation of Derrida's groundbreaking juxtaposition of Hegel and Genet, forcing two incompatible discourses into dialogue with each other.

In this paper about Chile, Weber's taxonomy of rational behavior is used together with a genetic-structural approach to explain chilean political life, which can be understood by the following variables : a mean demography, an authoritarian and religious culture, a capitalistic, dependent and under-developed economy, an hybrid social stratification, a centralised state characterized by an higly developed burocracy.In such a context the «Popular Unity» results from a specific acculturationof antagonistic ideologies related to different social strata, to competitive political groups as (...) welt as to rival pressure groups. In the short term ; the confiicting interests might coexist thanks to a growing social support motivated by a superficial economie nationalism, emotional anti-capitalistic feelings and the rise in the income of the popular and middle classes strata.On the other hand, the left government, divided by social, political and ideological oppositions was unable to run the civil service, to structure a congruent economic policy and to face international or national subversion.

Jacques Derrida is probably the most famous European philosopher alive today. The University of Nebraska Press makes available for the first English translation of his most important work to date, Glas. Its appearance will assist Derrida's readers pro and con in coming to terms with a complex and controversial book. Glas extensively reworks the problems of reading and writing in philosophy and literature; questions the possibility of linear reading and its consequent notions of theme, author, narrative, and discursive demonstration; (...) and ingeniously disrupts the positions of reader and writer in the text. Glas is extraordinary in many ways, most obviously in its typography. Arranged in two columns, with inserted sections within these, the book simultaneously discusses Hegel’s philosophy and Jean Genet’s fiction, and shows how two such seemingly distinct kinds of criticism can reflect and influence one another. The customary segregation of philosophy, rhetoric, psychoanalysis, linguistics, history, and poetics is systematically subverted. In design and content, the books calls into question “types” of literature (history, philosophy, literary criticism), the ownership of ideas and styles, the glorification of literary heroes, and the limits of literary representation.

Theoretical minimal RNA rings attempt to mimick life’s primitive RNAs. At most 25 22-nucleotide-long RNA rings code once for each biotic amino acid, a start and a stop codon and form a stem-loop hairpin, resembling consensus tRNAs. We calculated, for each RNA ring’s 22 potential splicing positions, similarities of predicted secondary structures with tRNA vs. rRNA secondary structures. Assuming rRNAs partly derived from tRNA accretions, we predict positive associations between relative secondary structure similarities with rRNAs over tRNAs and genetic code (...) integration orders of RNA ring anticodon cognate amino acids. Analyses consider for each secondary structure all nucleotide triplets as potential anticodon. Anticodons for ancient, chemically inert cognate amino acids are most frequent in the 25 RNA rings. For RNA rings with primordial cognate amino acids according to tRNA-homology-derived anticodons, tRNA-homology and coding sequences coincide, these are separate for predicted cognate amino acids that presumably integrated late the genetic code. RNA ring secondary structure similarity with rRNA over tRNA secondary structures associates best with genetic code integration orders of anticodon cognate amino acids when assuming split anticodons (one and two nucleotides at the spliced RNA ring 5′ and 3′ extremities, respectively), and at predicted anticodon location in the spliced RNA ring’s midst. Results confirm RNA ring homologies with tRNAs and CDs, ancestral status of tRNA half genes split at anticodons, the tRNA-rRNA axis of RNA evolution, and that single theoretical minimal RNA rings potentially produce near-complete proto-tRNA sets. Hence genetic code pre-existence determines 25 short circular gene- and tRNA-like RNAs. Accounting for each potential splicing position, each RNA ring potentially translates most amino acids, realistically mimicks evolution of the tRNA-rRNA translation machinery. These RNA rings ‘of creation’ remind the uroboros’ (snake biting its tail) symbolism for creative regeneration. (shrink)

The role of behaviour in biological evolution is examined within the context of Darwinism. All Darwinian models are based on the distinction of two mechanisms: one that permits faithful transmission of a feature from one generation to another, and another that differentially regulates the degree of this transmission. Behaviour plays a minimal role as an agent of transmission in the greater part of the animal kingdom; by contrast, the forms it may assume strongly influence the mechanisms of selection regulating the (...) different rates of transmission. We consider the decisive feature of the human species to be the existence of a phenotypical system of cultural coding characterized by precision and reliability which are the distinctive features of genetic coding in animals. We examine the consequences for the application of the Darwinian model to human history. (shrink)

"In this newest installment in Chicagos series of Jacques Derridas seminars, the renowned philosopher attempts one of his most ambitious goals: the first truly philosophical argument against the death penalty. While much has been written against the death penalty, Derrida contends that Western philosophy is massively, if not always overtly, complicit with a logic in which a sovereign state has the right to take a life. Haunted by this notion, he turns to the key places where such logic has (...) been established - and to the place it has been most effectively challenged: literature. With his signature genius and patient yet dazzling readings of an impressive breadth of texts, Derrida examines everything from the Bible to Plato to Camus to Jean Genet, with special attention to Kant and postWorld War II juridical texts, to draw the landscape of death penalty discourses. Keeping clearly in view the death rows and execution chambers of the United States, he shows how arguments surrounding cruel and unusual punishment depend on what he calls an 'anesthesial logic, ' which has also driven the development of death penalty technology from the French guillotine to lethal injection. Confronting a demand for philosophical rigor, he pursues provocative analyses of the shortcomings of abolitionist discourse. Above all, he argues that the death penalty and its attendant technologies are products of a desire to put an end to one of the most fundamental qualities of our finite existence: the radical uncertainty of when we will die.

In this 2004 interview — translated into English and published in its entirety for the first time — Jacques Derrida reflects upon his practices of writing and teaching, about the community of his readers, and explores questions related to corporeity and textuality, sexual difference, desire, politics, Marxism, violence, truth, interpretation, and translation. In the course of the interview, Derrida discusses the work of Martin Heidegger, Hans-Georg Gadamer, Maurice Blanchot, Hélène Cixous, Jean Genet, Paul Celan, and many others.

The genetic code has evolved from its initial non-degenerate wobble version until reaching its present state of degeneracy. By using the stereochemical hypothesis, we revisit the problem of codon assignations to the synonymy classes of amino-acids. We obtain these classes with a simple classifier based on physico-chemical properties of nucleic bases, like hydrophobicity and molecular weight. Then we propose simple RNA ring structures that present, overlap included, one and only one codon by synonymy class as solutions of a combinatory variational (...) problem. We compare these solutions to sequences of present RNAs considered as relics, with a high interspecific invariance, like invariant parts of tRNAs and micro-RNAs. We conclude by emphasizing some optimal properties of the genetic code. (shrink)

Rendell & Whitehead's minimalist definition of culture does not allow for the important gaps between cetaceans and humans. A more complete analysis reveals important discontinuities that may be more instructive for comparative purposes than the continuities emphasized by the authors.

Theoretical minimal RNA rings are candidate primordial genes evolved for non‐redundant coding of the genetic code's 22 coding signals (one codon per biogenic amino acid, a start and a stop codon) over the shortest possible length: 29520 22‐nucleotide‐long RNA rings solve this min‐max constraint. Numerous RNA ring properties are reminiscent of natural genes. Here we present analyses showing that all RNA rings lack dinucleotide CG (a mutable, chemically instable dinucleotide coding for Arginine), bearing a resemblance to known CG‐depleted genomes. CG (...) in “incomplete” RNA rings (not coding for all coding signals, with only 3–12 nucleotides) gradually decreases towards CG absence in complete, 22‐nucleotide‐long RNA rings. Presumably, feedback loops during RNA ring growth during evolution (when amino acid assignment fixed the genetic code) assigned Arg to codons lacking CG (AGR) to avoid CG. Hence, as a chemical property of base pairs, CG mutability restructured the genetic code, thereby establishing itself as genetically encoded biological information. (shrink)

The combination of the issue of return of individual genetic results/incidental findings and paediatric biobanks is not much discussed in ethical literature. The traditional arguments pro and con return of such findings focus on principles such as respect for persons, autonomy and solidarity. Two dimensions have been distilled from the discussion on return of individual results in a genetic research context: the respect for a participant’s autonomy and the duty of the researcher. Concepts such as autonomy and solidarity do not (...) fit easily in the discussion when paediatric biobanks are concerned. Although parents may be allowed to enrol children in minimal risk genetic research on stored tissue samples, they should not be given the option to opt out of receiving important health information. Also, children have a right to an open future: parents do not have the right to access any genetic data that a biobank holds on their children. In this respect, the guidelines on genetic testing of minors are applicable. With regard to the duty of the researcher the question of whether researchers have a more stringent duty to return important health information when their research subjects are children is more difficult to answer. A researcher’s primary duty is to perform useful research, a policy to return individual results must not hamper this task. The fact that vulnerable children are concerned, is an additional factor that should be considered when a policy of returning results is laid down for a specific collection or research project.

The mechanisms of Darwinian theory applied at the cellular level can explain the embryogenesis of an organism. On the one hand, DNA is not the bearer or carrier of a program composed of rigid instructions, in which the adult organism is « written », in advance. It is a generator of diversity that functions in a probabilistic fashion and thus enables cells to change states without being guided by signals. On the other hand, the environment is not only that which (...) is external to the organism. It exists within the embryo inasmuch as it constitutes the micro-environment of the cell. It determines the concentration of metabolites to which the cell has access and which enable it to multiply. In a colony of cells there are numerous variations in the composition of this microenvironment. Cells exchange the products of their metabolism. They use what their neighbours provide them. By means of their probabilistic functioning, they adapt to changing life conditions by activating the necessary proteins, whence the cellular differentiation generating the tissue of which an adult being is composed. In this theory, the embryo is not the passive object subject to the cumulative determinisms of the genome and the environment. These are integrated into a single mechanism. The cell is the fundamental level which constructs the living being by an active process of Darwinian selection. By bringing together phylogeness and ontogenesis in one explanatory model, cellular Darwinism allows us to get rid of the old concepts of purposiveness and formal cause which genetics has rehabilitated in the new clothing of the « generic program ».

The genetically manipulated organism crisis demonstrated that technological development based solely on the law of the marketplace and State protection against serious risks to health and safety is no longer a warrant of ethical acceptability. In the first part of our paper, we critique the implicitly individualist social-acceptance model for State regulation of technology and recommend an interdisciplinary approach for comprehensive analysis of the impacts and ethical acceptability of technologies. In the second part, we present a framework for the analysis (...) of impacts and acceptability, devised—with the goal of supporting the development of specific nanotechnological applications—by a team of researchers from various disciplines. At the conceptual level, this analytic framework is intended to make explicit those various operations required in preparing a judgement about the acceptability of technologies that have been implicit in the classical analysis of toxicological risk. On a practical level, we present a reflective tool that makes it possible to take into account all the dimensions involved and understand the reasons invoked in determining impacts, assessing them, and arriving at a judgement about acceptability.

Five years ago, an article co-written by two of us (Joly and Simard) presented an emerging trend to disclose certain individual genetic results to research participants. Since then, both technologies and research practices have evolved significantly. Given this rapid evolution, our goal is to provide updated and thorough guidance on this issue. Our paper begins by identifying the ethical principles that support the return of results: justice, beneficence, and respect for persons. Then, it presents the results of an analysis of (...) international norms on the return of results, covering both general and individual research results. It reveals existing divergence and consensus on these topics within the international community. With the goal of promoting greater harmonization, we conclude by proposing a flexible framework for the return of individual research results. (shrink)

Five years ago, an article co-written by some of us presented an emerging trend to disclose some individual genetic results to research participants within the international research community. At the time, ethical norms and scholarly publications on the return of results often did not distinguish between the return of research results in general and the return of unexpected results. Both technologies and research practices have evolved significantly. Today whole genome and exome sequencing are increasingly affordable and frequently used in genetic (...) research. Because these techniques produce a vast amount of interpretable and non-interpretable data about an individual, the issue of how to manage information generated by such technologies needs to be considered. However, the development of international ethical guidelines has not kept up with the rapid pace of technological progress. Indeed developments in genomic biobanking also challenge the duty to disclose research results. (shrink)

Glassary is a companion volume to Glas. It offers English readers fuller access to the masterwork of Jacques Derrida, the leading philosopher in France. Derrida is important for his investigations of language, philosophy, and writing. He has perforated the boundaries between academic disciplines, has demonstrated the theological underpinnings of apparently atheological philosophies, and has thrown into question traditional notions about the "ownership" of ideas. Glas exemplifies Derrida's methodology of reading and his central philosophical and literary concerns. The reader fascinated (...) by its complexities will appreciate the assistance of Glassary. Written by the chief translator of Glas, John P. Leavey, Jr., it includes an essay by Gregory Ulmer and a foreword by Jacques Derrida. The book provides all of the apparatus a reader of Glas might immediately desire, including notes on difficult or ambiguous passages, identifications of allusions and puns, locations of citations, and translations of passages in languages other than French. But Leavey does not stop there. He includes a glossary of use to readers of Glas in any language and essays that relate it to Derrida's texts and to the modern French critical enterprise as a whole. Leavey's essay focuses on Glas and literature and philosophy; Ulmer's on Glas and psychoanalysis. (shrink)

Normal fetal development is dependent upon an intricate exchange between mother and embryo. Several maternal and embryonic elements can influence this intimate interaction, including genetic, environmental or epigenetic factors, and have a significant impact on embryo development. The interaction of the genetic program of both mother and embryo, within the uterine environment, can shape the development of an individual. Accumulating data from animal models indicate that prenatal events may well initiate long‐term changes in the expression of the embryo genetic program, (...) which persist, or may only become apparent, much later in the individual's life. Also, environmental conditions during prenatal development may prompt the adoption of different developmental pathways, leading to alternative life histories. This review focuses on environmental factors, specifically maternally derived molecules, to illustrate how they can influence in utero embryonic development and, by extension, adult life. (shrink)

The genetic code has been regarded as arbitrary in the sense that the codon-amino acid assignments could be different than they actually are. This general idea has been spelled out differently by previous, often rather implicit accounts of arbitrariness. They have drawn on the frozen accident theory, on evolutionary contingency, on alternative causal pathways, and on the absence of direct stereochemical interactions between codons and amino acids. It has also been suggested that the arbitrariness of the genetic code justifies attributing (...) semantic information to macromolecules, notably to DNA. I argue that these accounts of arbitrariness are unsatisfactory. I propose that the code is arbitrary in the sense of Jacques Monod's concept of chemical arbitrariness: the genetic code is arbitrary in that any codon requires certain chemical and structural properties to specify a particular amino acid, but these properties are not required in virtue of a principle of chemistry. This notion of arbitrariness is compatible with several recent hypotheses about code evolution. I maintain that the code's chemical arbitrariness is neither sufficient nor necessary for attributing semantic information to nucleic acids. (shrink)

This volume reflects on the effects of recent discoveries in genetics on a broad range of scientific fields. In addition to neuroscience, evolutionary biology, anthropology and medicine, contributors analyze the effects of genetics on theories of health, law, epistemology and philosophy of biology. Social and moral concerns about the relationship between genetics, society and the individual also figure prominently. Genetic discoveries fuel central contemporary public policy debates concerning, for example, human cloning, equitable access to healthcare or the role of genetics (...) in medicine. Perhaps more fundamentally, advances in genetics are altering our perception of human life and death. An interview with François Jacob by Anne Fagot-Largeault opens the volume. In this interview, Jacob, who shared a Nobel Prize with André Lwoff and Jacques Monod for their discoveries concerning genetic control of enzyme and virus synthesis, addresses many of the central methodological epistemological and ethical questions covered in the volume. The dynamic interdisciplinary character of this volume makes it relevant to scholars from many disciplines, from biology, philosophy and the social sciences. (shrink)

Although much headway has been made since the Derridean notion of the ‘general text’ was recuperated by eco-critics to imbue the philosophy of life with deconstructive rigor, the recent publication of Jacques Derrida’s Life Death seminar provides an opportunity for a renewed engagement. Parallel to his sustained elaboration of a non-dialectical reckoning with life (death) were a series of developments in the study of thermodynamic complex systems that similarly sought to demystify the pervasive vitalism within the life sciences. Derrida’s (...) grammatological interrogation of the life/death dialectic takes the ‘textualization’ of genetic life as a starting point for articulating a logic of supplementarity that reorients our position in relation to our lived environments. ‘Writing’, however, cannot help but invoke the archive along with all its destructive impulses (Destruktionstrieb). If the archive invokes the law of the house (oikos), then the archive perhaps names the archive of the archive, which Derrida was all too aware of as the site for the annihilation of memory and the release of pure loss. A grammatological reading of this entropic textuality would thus consider how the irreducibility of absolute destruction might nevertheless offer a path ‘toward the incalculability of another thought of life.’.

A common feature of scientific and ethical debates is that clones are generally described and understood as “copies” or, more specifically defined, as “genetic copies.” The attempt of this paper is to question this widespread definition. It first argues that the terminology of “clone as copy” can only be understood as a metaphor, and therefore, a clone is not a “genetic copy” in a strict literal sense, but in a figurative one. Second, the copy metaphor has a normative component that (...) is problematic in the context of descriptive science and may support or indicate the ethically relevant phenomenon of objectification of animals. In order to support the argument against the common conception of a clone as a copy, the biotechnological principles of somatic cell nuclear transfer cloning will be examined. On this basis, it will be shown that the metaphor is valid because of similarities between the phenotype, the genotype, or the nuclear DNA sequence of the clone and its progenitor by using three prominent levels of comparison. Focusing on the process of SCNT, it will be shown that cloning as copying or doubling has to be redefined for scientific purposes because it is neither necessary nor does it fit to the biotechnological principles of cloning. It is more accurate to understand SCNT cloning as a process of splitting rather than of doubling or copying. In the second part, a deconstructivist analysis based on Jacques Derrida’s description in Positions will reveal the normative potential of the original–copy dichotomy. I will be showing that it includes an asymmetrical power structure between the original and the copy and that this structure can be reversed or at least considered unstable. Therefore, arguments that build on that metaphor must be reconsidered. Moreover, the analysis reveals that applying a terminology to humans and animals that is commonly used for things becomes the language of objectification. Two selected examples, fungibility and violability, based on Martha Nussbaum’s notion of objectification will support the thesis of objectification, display its normative consequences, and put the clone as a copy metaphor in a broader range of ethically questionable research tendencies.

My article is a rejoinder to Gert Biesta’s, ‘“This is My Truth, Tell Me Yours”. Deconstructive pragmatism as a philosophy of education.’ Biesta attempts to place Jacques Derrida’s deconstruction in ‘the very heart’ of John Dewey’s pragmatism. My article strives to impress Deweyan pragmatism in the heart of Derridian deconstruction. It does so by offering Dewey’s denotative, naturalistic, empirical perspectivalism as an alternative to Derrida’s anti-empirical quasi-transcendentalism for understanding otherness and difference. The first section of my article shows Biesta (...) offers a catastrophically mistaken and confused argument. The second section imprints Deweyan pragmatism in the heart of Derrida’s deconstruction. Dewey specifically makes philosophical use of a version of the genetic method he calls the ‘empirical denotative method’ to trace the exclusions as well as the inclusions of our perspectival selections driven by our finite embodied needs, interest, desires, and purposes. We may derive the trace of quasi-transcendental différance from the trace of empirically perspectival inclusions and exclusions. Specifically, différance is a reified hypostatic abstraction. Next, I respond to Biesta’s claim that since the metaphysics of presence still entangles Dewey, he cannot appreciate the fact that presence depends on absence. Actually, presence in Dewey always depends on absence. Finally, we will find that Biesta’s own deconstructive pragmatism flounders on his commitment to self-refuting relativism. (shrink)

An analysis of Derrida’s early work engaging Plato, Hegel, and the life sciences. Germs of Death explores the idea of genesis, or dissemination, in the early work of Jacques Derrida. Looking at Derrida’s published and unpublished work from “Force and Signification” in 1963 to Glas in 1974, Mauro Senatore traces the development of Derrida’s understanding of genesis both linguistically and biologically, and argues that this topic is an overlooked thread that draws together Derrida’s readings of Plato and Hegel. Demonstrating (...) how Derrida’s analysis liberates the understanding of genesis from Platonic and Hegelian presupposition, Senatore also highlights Derrida’s engagement with the biological thought of his day. Senatore also shows that the implications of Derrida’s insights extend into contemporary ethical and political questions relating to postgenomic conceptions of life. “Senatore here demonstrates with stunning insight, clarity, and economy that Derrida’s work of the 1960s and ’70s needs to be understood as a radical critique or deconstruction of both the philosophical concept of life (from Plato to Hegel) and the prevailing biological model of heredity as a ‘genetic program.’ It will be impossible henceforth to read Derrida on questions of the trace, dissemination, life, and so on, without coming to terms with ‘the germs of death.’” — Michael Naas, author of The End of the World and Other Teachable Moments: Jacques Derrida’s Final Seminar “The book represents a major contribution to the field of Derrida studies and phenomenology, particularly its attention to the concept of genesis that formed the basis of Derrida’s earliest study of Husserl and the origin of his concept of writing. The unique contribution is the inclusion of the works from the periods of the mid-1970s, which have been neglected in the mainstream scholarship on Derrida.” — Gregg Lambert, author of Philosophy after Friendship: Deleuze’s Conceptual Personae.

Diauxie is at the origin of research that led Jacques Monod, François Jacob, and André Lwoff to win the Nobel Prize in Physiology or Medicine in 1965 for their description of the first genetic regulatory model. Diauxie is a term coined by Jacques Monod in 1941 in his doctoral dissertation that refers to microbial growth in two phases. In this article, we first examine Monod’s thesis to demonstrate how and why Monod interpreted diauxie as a phenomenon of enzyme (...) inhibition or suppression of adaptive enzymes. We also briefly investigate prior enzyme suppression studies, before Monod’s work, which indicate that he is the first person to observe diauxic growth. Second, we analyse Monod’s post-thesis publications throughout his scientific career, revealing that diauxic inhibition was a significant part of Monod’s scientific activities and greatly fascinated Monod until the end of his life. Paradoxically, Monod’s work and interest on diauxic inhibition are still neglected in historical recounts, focused mostly on Monod’s enzymatic adaptation studies. Indeed, we uncovered a statement by Monod’s colleague, Lwoff, who transformed a quotation from Monod by replacing the word phenomenon with enzymatic adaptation, which we believe has influenced historians. Finally, we offer hypotheses to explain why Lwoff altered Monod’s statement. (shrink)

1900 was a remarkable year for science. Several ground-breaking events took place, in physics, biology and psychology. Planck introduced the quantum concept, the work of Mendel was rediscovered, and Sigmund Freud published The Interpretation of Dreams . These events heralded the emergence of completely new areas of inquiry, all of which greatly affected the intellectual landscape of the 20 th century, namely quantum physics, genetics and psychoanalysis. What do these developments have in common? Can we discern a family likeness, a (...) basic affinity between them, so that we can use the one to deepen our understanding of the other? One common denominator is that they open up realms of inquiry that are significantly different from the world of everyday experience, namely the realm of elementary particles, of genes and genomes, and of the unconscious. But to what extent can we meaningfully argue, for instance, that the genome is the biological unconscious, and the unconscious the psychic genome? To address these questions, I will build on the work of two key intellectual figures who have explored the affinities of these developments in depth, namely Erwin Schrödinger (a quantum physicist and avid reader of Schopenhauer who initiated molecular biology) and Jacques Lacan (who reframed the specificity of psychoanalysis with the help of 20 th century science: the era of structural linguistics, but also of quantum physics, molecular biology, bioinformatics and DNA).

Since the 1930’s, several attempts have been made to develop a general theory of technical systems or objects and their evolution: in France, Jacques Lafitte, André Leroi-Gourhan, Bertrand Gille, Yves Deforge, and Gilbert Simondon are the main representatives of this trend. In this paper, we focus on the work of Simondon: his analysis of technical progress is based on the hypothesis that technology has its own laws and that customer demand has no paramount influence upon the evolution of technical (...) systems. We first describe the process Simondon called “concretization” and compare it with the process of “idealization” as defined by Genrich Altshuller. We then explain how the progress of technical lineages can be characterized as following a specific rhythm of relaxation and how it thus obeys a “law” of evolution in the industrial context. Simondon’s theoretical approach, although similar to some aspects of methodologies of conception, emphasized a more accurate understanding of technical progress over possible operational applications. Simondon never intended to optimize the engineer’s tasks from an economic point of view and, in fact, his conception of technical progress can be considered as independent from the capitalistic trend of innovation. However, the philosophy of Simondon provides a better understanding of what is at stake theoretically in the modeling of laws of technical evolution. (shrink)

La vie la mort est l'un des séminaires les plus féconds de Jacques Derrida. En jeu : penser la vie et la mort en vertu d'une logique qui ne poserait pas la mort comme l'opposé de la vie. La pureté de la vie n'est-elle pas, par essence, contaminée par la possibilité même de la mort, puisque seul un vivant peut mourir? interroge d'emblée le philosophe. En renversant la perspective classique, Derrida entreprend d'enseigner à ses étudiants que c'est la mort, (...) au contraire, qui rend la vie possible. En quatorze séances érudites et palpitantes délivrées au cours de l'année 1975-1976, Derrida déconstruit l'opposition traditionnelle entre la vie et la mort à travers des lectures multiples et délibérément pluridisciplinaires, élaborant sa pensée aussi bien au contact de la philosophie (Hegel, Nietzsche, Heidegger) et de l'épistémologie des sciences (Georges Canguilhem) que dans la confrontation à la génétique contemporaine (François Jacob) et à la psychanalyse (catégories freudiennes de pulsions de vie et de mort)."--Page 4 of cover.

Cet ouvrage aurait pu s'intituler " matière et vie ". L'auteur nous guide sur le long chemin qui va des constituants élémentaires d'un jeune univers, dans lequel la vie est évidemment absente, jusqu'aux formes complexes de la matière. Il explique comment et pourquoi la matière se complexifie dans le coeur des étoiles de premières générations, dans la nébuleuse protosolaire, sur la jeune Terre envoie de différenciation, dans les premiers océans terrestres. Il décrit ce que l'on croit savoir, mais aussi passe (...) en revue tout ce que l'on ignore à propos de la génération spontanée des premières cellules vivantes. Lorsque la vie apparaît, l'histoire de la matière devient dépendante de l'évolution biologique. Après trois milliards d'années environ, celle-ci conduit à l'apparition de l'homme, seul être vivant capable de faire évoluer la matière. Ce livre propose ainsi une fresque d'une réelle ampleur, sans équivalent à ce jour, écrite pour être accessible à tous. Et pourtant, les questions abordées relèvent de nombreuses disciplines, comme l'astrophysique, la biologie, la chimie, le génie génétique et l'histoire des techniques. (shrink)

"Reading Voice and Phenomenon from a phenomenological perspective, this paper argues that the book is an internal criticism of Husserlian phenomenology that, among other things, can serve as an introduction to Husserl’s genetic method. Derrida’s most powerful arguments are delivered by turning the Cartesian method of Logical Investigations and Ideas I to Husserl’s inquiries into time-consciousness; as such, it is a phenomenological criticism through and through. An analysis of Husserl’s later manuscripts and lectures published posthumously shows that driven by what (...) Derrida calls the radicality of intuitionism, Husserl has developed a genetic phenomenological method that breaks free from the metaphysics of presence and arrived at a conception of meaning and language that is similar to Derrida’s. Keywords: genetic phenomenology; Edmund Husserl; Jacques Derrida; Voice and Phenomenon". (shrink)
