The aim of this book is to show how supramolecular complexity of cell organization can dramatically alter the functions of individual macromolecules within a cell. The emergence of new functions which appear as a consequence of supramolecular complexity, is explained in terms of physical chemistry. The book is interdisciplinary, at the border between cell biochemistry, physics and physical chemistry. This interdisciplinarity does not result in the use of physical techniques but from the use of physical concepts to study biological problems. (...) In the domain of complexity studies, most works are purely theoretical or based on computer simulation. The present book is partly theoretical, partly experimental and theory is always based on experimental results. Moreover, the book encompasses in a unified manner the dynamic aspects of many different biological fields ranging from dynamics to pattern emergence in a young embryo. The volume puts emphasis on dynamic physical studies of biological events. It also develops, in a unified perspective, this new interdisciplinary approach of various important problems of cell biology and chemistry, ranging from enzyme dynamics to pattern formation during embryo development, thus paving the way to what may become a central issue of future biology.

Trichoderma ATCC 20476 based biofungicides have been marketed continuously on a small scale for 20 years. A more recently developed application for these biofungicides is the treatment of strawberries against the gray mold Botrytis cinerea. That application is examined in terms of Lockwood's criteria for ethics in biological control. Unaddressed risks resulting from the current scramble for market share in northern Europe are pointed out.

This volume is a collection of twenty-three interviews given over the last two decades. It illustrates the extraordinary breadth of Derrida's concerns, touching upon such subjects as the teaching of philosophy, sexual difference and feminine identity, the media, AIDS, language and translation, nationalism, politics, and Derrida's early life and the history of his writings. Often, as in the interviews on Heidegger, on drugs, or on the nature of poetry, these interviews offer something available nowhere else in his work. The informality (...) of the interview process frequently leads to the most succinct and lucid explications of many of the most important and influential aspects of Derrida's thought. Sixteen of the interviews appear in English for the first time, including an interview conducted especially for this volume, concerning the recent exchange of letters in the New York Review of Books.

Entre les postes et le mouvement analytique, le principe de plaisir et l'histoire des télécommunications, la carte postale et la lettre volée, bref le transfert de Socrate à Freud, et au-delà. Cette satire de la littérature épistolaire devait être farcie - d'adresses, de codes postaux, de missives cryptées, de lettres anonymes, le tout confié à tant de modes, de genres et de tons.

Prácticamente casi todos los temas básicos que conforman la agenda política y social de esta década están relacionados con dos categorías básicas: la ciudadanía y la multiculturalidad. La forma en cómo se gestiona el vínculo de estos dos pilares básicos constituye el principal factor de transformación social, política y cultural de nuestra época. El objetivo de este capítulo es doble: por un lado, y en relación al tema general de este monográfico, argumentar que el tema de la inmigración forma parte (...) de una dinámica más amplia de discusiones sobre los fundamentos básicos de nuestra época moderna, resultado del doble proceso de State-Building y de Nation-building; por otro lado, subrayar que la primera "víctima" de este proceso de cambio contextual es precisamente el producto de este doble movimiento histórico: la noción tradicional de ciudadanía, que tiene dificultades de encontrar recursos para gestionar los nuevos fenómenos ligados con la multiculturalidad. En este marco, nos plantearemos como pregunta básica: ¿en qué sentido el multiculturalismo plantea problemas a la tradición de la ciudadanía? Partiremos de la situación siguiente: ¿qué ocurre cuando se usa la noción tradicional de la ciudadanía en contextos de multiculturalidad?. Estructuré mi argumentación en cinco secciones. En la primera sección, introduciré el marco conceptual dentro del cual se ubican las discusiones actuales, compuesto de tres elementos básicos: el Estado, la Nación y la Ciudadanía. En la segunda sección, entraremos en la discusión sobre el concepto tradicional de la ciudadanía, centrándonos en su base normativa y empírica desde una perspectiva comparativa. En la tercera sección, nos ocuparemos del concepto de multiculturalismo. En la cuarta sección me ocuparé de lo que he titulado como los "contextos de la multiculturalidad", esto es, las diferentes dimensiones que ponen en entredicho el carácter indivisible (y sagrado) del Estado, la Nación y la Ciudadanía. Introduciremos, sucesivamente, el pluralismo de identidades culturales, el pluralismo de identidades nacionales, la inmigración, la construcción política de la Unión Europea y, por último, la globalización. Finalmente, en una quinta y última sección, haremos un balance final dando un sentido histórico a nuestros razonamientos. (shrink)

El tema predilecto en la filosofía moderna ha sido desde sus comienzos el de la subjetividad. Una subjetividad que ha permitido grandes avances pero también peligros para el ser humano, y es que al centrarse demasiado en la conciencia de sí mismo, el hombre y su filosofía han perdido la conexión con la realidad racional con la que conviven. El idealismo hegeliano, entendido como filosofía del espíritu, pretende ser a la vez una superación de este distanciamiento mutuo y una nueva (...) forma de comprender la filosofía, el hombre, la realidad y la articulación racional que todos ellos encuentran en lo absoluto.

Podríamos calificar a Nietzsche de un profeta heroico e innovador, que hace un oráculo de la decadencia, denunciando el triunfo de lo suprasensible, de lo ideal, la imposición de otro mundo como la historia de un error, de una ilusión, fuente común de todas las ficciones, prejuicios y dogmatismos de la tradición cultural occidental. Sin embargo, el pensamiento que Nietzsche expresa con la muerte de dios, y que conlleva el fin del cristianismo y de la metafísica, tiene un origen metafísico (...) y un origen genuinamente cristiano.

La 4e de couverture indique : "Les thèses de Lacan viennent de sa pratique, mais il avait articulé celles-ci dans un cadre théorique très élaboré. De Platon et Descartes jusqu'à Heidegger ou Wittgenstein, en passant par Kant et Hegel, Lacan a lu avec attention les grands philosophes. Le refondateur de la psychanalyse, à l'encontre des scolastiques de la psyché qu'il a sans cesse combattues, avait à faire à la vérité, à la vérité freudienne, celle des sujets qui s'analysent, mais aussi (...) aux articulations de savoir qui prennent une place primordiale dans l'élaboration de son immense séminaire qui constitue une des créations les plus puissantes de notre temps. Les grands philosophes y sont fréquemment interrogés dans leur pensée fondamentale et jusqu'à leur point de butée que Lacan nommait l'impossible et qu'il tentait de déborder à partir des (quatre) concepts fondamentaux de Freud et en posant avec l'objet a le registre du Réel et le primat de l'écriture.".

"In this densely imbricated volume Derrida pursues his devoted, relentless dismantling of the philosophical tradition, the tradition of Plato, Kant, Hegel, Nietzsche, Husserl, Heidegger--each dealt with in one or more of the essays. There are essays too on linguistics (Saussure, Benveniste, Austin) and on the nature of metaphor ("White Mythology"), the latter with important implications for literary theory. Derrida is fully in control of a dazzling stylistic register in this book--a source of true illumination for those prepared to follow his (...) arduous path. Bass is a superb translator and annotator. His notes on the multilingual allusions and puns are a great service."--Alexander Gelley, Library Journal. (shrink)

The paper deals with the contributions of Jacques Herbrand to logic and philosophy in historical context.

En este artículo exponemos las intuiciones del teólogo y biólogo alemán Karl Schmitz-Moormann sobre la evolución. Como leitmotiv subyacente en toda su obra, Schmitz-Moormann tiene a Teilhard de Chardin. Inspirado por Teilhard y su metafísica de la unión, introduce un nuevo concepto, a saber, la uni-totalidad. Veremos aquí cómo Schmitz-Moormann observa diversas uni-totalidades a lo largo del progreso evolutivo, desde las partículas subatómicas hasta las agrupaciones humanas. Esas diversas uni-totalidades implican, a la vez, diversidad de unión, que puede ser explicada (...) por causas que van desde la interacción nuclear hasta el amor interpersonal. Análogamente, Schmitz-Moormann ve nuestro Dios tri-uno como la Uni-totalidad suprema unida por amor, a la que se acercan las uni-totalidades creadas. (shrink)

Responding to questions put to him at a Roundtable held at Villanova University in 1994, Jacques Derrida leads the reader through an illuminating discussion of the central themes of deconstruction. Speaking in English and extemporaneously, Derrida takes up with unusual clarity and great eloquence such topics as the task of philosophy, the Greeks, justice, responsibility, the gift, the community, the distinction between the messianic and the concrete messianisms, and his interpretation of James Joyce. Derrida convincingly refutes the charges of (...) relativism and nihilism that are often leveled at deconstruction by its critics and sets forth the profoundly affirmative and ethico-political thrust of his work. The “Roundtable” is marked by the unusual clarity of Derrida’s presentation and by the deep respect for the great works of the philosophical and literary tradition with which he characterizes his philosophical work. The Roundtable is annotated by John D. Caputo, the David R. Cook Professor of Philosophy at Villanova University, who has supplied cross references to Derrida’s writings where the reader may find further discussion on these topics. Professor Caputo has also supplied a commentary which elaborates the principal issues raised in the Roundtable. In all, this volume represents one of the most lucid, compact and reliable introductions to Derrida and deconstruction available in any language. An ideal volume for students approaching Derrida for the first time, Deconstruction in a Nutshell will prove instructive and illuminating as well for those already familiar with Derrida’s work.

" "Positions brings together three interviews with Derrida, outlining his central concerns and ideas.

These two lectures by Jacques Derrida, 'Foreigner Question: Come from Abroad' and 'Step of Hospitality/No Hospitality', derive from a series of seminars on 'hospitality' conducted by Derrida in Paris, January 1996. The book consists of two texts on facing pages. 'Invitation' by Anne Dufourmantelle appears on the left clarifying and inflecting Derrida's 'response' on the right. The interaction between them not only enacts the 'hospitality' under discussion, but preserves something of the rhythms of teaching. The book also characteristically combines (...) careful readings of canonical texts and philosophical topics with attention to the most salient events in the contemporary world, using 'hospitality' as a means of rethinking a range of political and ethical situations. For example, Antigone is revisited in light of the question of impossible mourning; the trial of Socrates is brought into conjunction with the televised funeral of François Mitterrand. (shrink)

El presente artículo recoge los resultados de una investigación basada en el análisis comparado de la estética de los museos creados en ciudades que forman parte de la denominada Ruta de la Seda. La aproximación a estos museos se basa principalmente en la observación de los aspectos educativos y patrimoniales, elementos que caracterizan la esencia de dichas instituciones. UNESCO impulsa desde 1988 acciones vinculadas a la Ruta de la Seda, ruta comercial ahora reconvertida en ruta de diálogo entre culturas. Observamos (...) que cada museo estudiado ha insistido en aquellas cuestiones de rango local y nacional que caracterizan su idiosincrasia, potenciando las facetas educativas desde la tradición de la producción de seda, y también las cuestiones patrimoniales para afianzar los rasgos característicos de cada comunidad. Hemos entrevistado a sus responsables y observado en directo sus instalaciones y colecciones. Detectamos que, a pesar de la influencia internacional de la iniciativa, o bien precisamente por ello, en cada caso se ha optado por incidir en los factores diferenciales locales, primando los argumentos estéticos de identidad cultural. Examinamos el caso concreto del Museo de la Seda de Valencia, el de creación más reciente, pero que aloja la institución más antigua. (shrink)

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)

Is there, today," asks Jacques Derrida, "another 'question of religion'?" Derrida's writings on religion situate and raise anew questions of tradition, faith, and sacredness and their relation to philosophy and political culture. He has amply testified to his growing up in an Algerian Jewish, French-speaking family, to the complex impact of a certain Christianity on his surroundings and himself, and to his being deeply affected by religious persecution. Religion has made demands on Derrida, and, in turn, the study of (...) religion has benefited greatly from his extensive philosophical contributions to the field. Acts of Religion brings together for the first time Derrida's key writings on religion, along with two new essays translated by Gil Anidjar that appear here for the first time in any language. These texts are organized around the secret holding of links between the personal, the political, and the theological. In these texts, Derrida's reflections on religion span from negative theologyto the limits of reason and to hospitality. Acts of Religion will serve as an excellent introduction to Derrida's remarkable contribution to religious studies. (shrink)

Genomic instability is a hallmark of cancer. Cancer cells that exhibit abnormal chromosomes are characteristic of most advanced tumours, despite the potential threat represented by accumulated genetic damage. Carcinogenesis involves a loss of key components of the genetic and signalling molecular networks; hence some authors have suggested that this is part of a trend of cancer cells to behave as simple, minimal replicators. In this study, we explore this conjecture and suggest that, in the case of cancer, genomic instability has (...) an upper limit that is associated with a minimal cancer cell network. Such a network would include (for a given microenvironment) the basic molecular components that allow cells to replicate and respond to selective pressures. However, it would also exhibit internal fragilities that could be exploited by appropriate therapies targeting the DNA repair machinery. The implications of this hypothesis are discussed. (shrink)

A rich exploration of the idea of friendship and its political consequences, past and future, by the most influential of contemporary philosophers. Until relatively recently, Jacques Derrida was seen by many as nothing more than the high priest of Deconstruction, by turns stimulating and fascinating, yet always somewhat disengaged from the central political questions of our time. Or so it seemed. Derrida's "political turn," marked especially by the appearance of Specters of Marx, has surprised some and delighted others. In (...) The Politics of Friendship Derrida renews and enriches this orientation through an examination of the political history of the idea of friendship pursued down the ages. Derrida's thoughts are haunted throughout the book by the strange and provocative address attributed to Aristotle, "my friends, there is no friend" and its inversions by later philosophers such as Montaigne, Kant, Nietzsche, Schmitt and Blanchot. The exploration allows Derrida to recall and restage the ways in which all the oppositional couples of Western philosophy and political thought—friendship and enmity, private and public life—have become madly and dangerously unstable. At the same time he dissects genealogy itself, the familiar and male-centered notion of fraternity and the virile virtue whose authority has gone unquestioned in our culture of friendship and our models of democracy The future of the political, for Derrida, becomes the future of friends, the invention of a radically new friendship, of a deeper and more inclusive democracy. This remarkable book, his most profoundly important for many years, offers a challenging and inspiring vision of that future. (shrink)

"The four essays in this volume constitute Derrida's most explicit and sustained reflection on the art work as pictorial artifact, a reflection partly by way of philosophical aesthetics (Kant, Heidegger), partly by way of a commentary on art works and art scholarship (Van Gogh, Adami, Titus-Carmel). The illustrations are excellent, and the translators, who clearly see their work as both a rendering and a transformation, add yet another dimension to this richly layered composition. Indispensable to collections emphasizing art criticism and (...) aesthetics."--Alexander Gelley, Library Journal. (shrink)

Leigh Van Valen was an American evolutionary biologist who made major contributions to evolutionary theory. He is particularly remembered for his groundbreaking paper “A New Evolutionary Law” (1973) where he provided evidence from fossil record data that the probability of extinction within any group remains essentially constant through time. In order to explain such an unexpected result, Van Valen formulated a very influential idea that he dubbed the “Red Queen hypothesis.” It states that the constant decay must be a consequence (...) of evolutionary interactions among connected species within ecological networks. In Van Valen’s picture, species do not merely evolve: they also coevolve with other species. As a consequence, when thinking about adaptation to an external environment, the other species must be considered as part (maybe a major part) of such an external world. Van Valen’s law provided the first complex systems theory of coevolutionary dynamics and inspired a whole range of theoretical and experimental developments from very diverse fields, percolating far beyond its original formulation. Red Queen arms races are nowadays considered a widespread feature of complex adaptive systems. (shrink)

Fluid neural networks can be used as a theoretical framework for a wide range of complex systems as social insects. In this article we show that collective logical gates can be built in such a way that complex computation can be possible by means of the interplay between local interactions and the collective creation of a global field. This is exemplified by a NOR gate. Some general implications for ant societies are outlined. ©.

The Discriptio Hispaniae is a passage from the Geometry of Gisemundus, also entitled Ars Gromatica Gisemundi, a medieval treatise of agrimensura written by an unknown author, probably a monk known as Gisemundus who had some agrimensorial experience. The work was compiled around AD 800 by collecting passages of a range of sizes, from just a few words to several pages, extracted from ancient and medieval sources. Although modern research into Roman agrimensorial texts has admitted the importance of the AGG, its (...) corrupt condition has not invited sustained analysis. The passage now known as the Discriptio Hispaniae, a short section from chapter three of the second book of the AGG entitled III De segregatione provinciarum ab Augustalibus terminis, is particularly interesting for the information that it provides concerning the territorial division of Hispania in Late Antiquity. This article presents an edition and English translation of the Discriptio Hispaniae and argues that the most likely point of origin for the Discriptio Hispaniae is during the Byzantine occupation of parts of southern Spain during the second half of the sixth century and the first quarter of the seventh century. We suggest that the Discriptio Hispaniae was preserved because the Byzantine authorities were keen to keep on record information about the borders of the province of Carthaginensis, perhaps the main theme in the text.

This book critically assesses the implications of modern medicine's claim to be a natural science. Medicine models its scientific and clinical self-understanding on an obsolete positivist conception of science, reality, and consciousness. In this view, the body is modeled as a biological machine, disease as breakdown of the machine, and therapy as physical measures to fix the machine. The problems besetting medical science and practice are rooted in the inadequacy of the positivist philosophical assumptions regarding the nature of science, reality (...) and consciousness To base the diagnostic practices and therapeutic regimes purely on knowledge of physical processes in the human body is, in view of this analysis, at best grossly inadequate, at worst thoroughly dehumanizing (Anton van Niekerk: Editorial Foreword). This means that medicine's clinical method cannot be transformed without transforming the underlying view of science, of reality, and of the human person. The book proposes a broader model of science which overcomes the outdated dichotomy between human and natural sciences. Science is viewed as an interdisciplinary exercise generating multiple perspectives. The insights of the human sciences are essential for scientific clinical medicine. Utilizing evolutionary biology and complexity theory, the author proposes an alternative understanding of reality and human consciousness as a basis for a transformed clinical method. Reality is a hierarchy of systems of increasing complexity. Different levels can be distinguished, namely material systems, living material systems, conscious living material systems and self-conscious living material systems. Each level represents a new manner of being which requires a different scientific discourse of understanding. Using this model of reality the author argues against understanding human consciousness as a byproduct of physical processes in the brain. The human person is a self-conscious, complex, psycho-somatic system, whose well-being is conditioned by much more than physical processes. (shrink)

This volume reflects Derrida's engagement in the late 1970s with French political debates on the teaching of philosophy and the reform of the French university system. While addressing specific contemporary political issues, the essays deal mainly with much broader concerns. With his typical rigor and spark, Derrida investigates the genealogy of several central concepts which any debate about teaching and the university must confront. Thus there are essays on the 'teaching body', both the faculty corps and the strange interplay in (...) the French tradition between the mind and body of the professor; on the question of age in teaching, analyzed through a famous letter of Hegel; on the class, the classroom, and the socio-economic concept of class in education; on language, especially so-called 'natural languages' like French; and on the legacy of the revolutionary tradition, the Estates General, in the university.
