The process of chromatin diminution in Parascaris and Ascaris is a developmentally controlled genome rearrangement, which results in quantitative and qualitative differences in DNA content between germ line and somatic cells. Chromatin diminution involves chromosomal breakage, new telomere formation and DNA degradation. The programmed elimination of chromatin in presomatic cells might serve as an alternative way of gene regulation. We put forward a new hypothesis of how an ancient partial genome duplication and chromatin diminution may have served to maintain the (...) genetic balance in somatic cells and simultaneously endowed the germ line cells with a selective advantage.

The implicit activities of the living body in sports (such as heart rate, involuntary gestures, stress, reflex, emotional regulation and interaction expressions) emerge in the consciousness of the lived body without our voluntary control. We demonstrate physiological emersion, and how, including in dramaturgical perception, physiological flows and processes collide with the image of a whole body. In this paper, we introduce corporeal non-property as the missing (?) link between phenomenology and neuroscience, renewed by research on the cerebral unconscious and the (...) perception of their lived body. Rather than mindfulness, physical activity obliges the subject to learn the unconscious and his motor skills from his living body: a new psychoanalysis of sport is thus established by studying what emerges from the activity of the living body up to the level of the conscious description of motor action. In this paper, we explain why that awareness occurs, and why it matters for the understanding of unconscious activity of the athlete’s living body. This is potentially interesting, although it needs, as a theory, to overcome the obvious reliance of the body on unconscious or habitual/automated physiological processes. But the incorporation of body techniques forms a habitus. (shrink)

New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

Although complex hallucinations are extremely vivid, painful symptoms in schizophrenia, little is known about the underlying mechanisms of multisensory integration in such a phenomenon. We investigated the neural basis of these altered states of consciousness in a patient with schizophrenia, by combining state of the art neuroscientific exploratory methods like functional MRI, diffusion tensor imaging, cortical thickness analysis, electrical source reconstruction and trans-cranial magnetic stimulation. The results shed light on the functional architecture of the hallucinatory processes, in which unimodal information (...) from different modalities is strongly functionally connected to higher-order integrative areas.

This essay engages with Bernard Stiegler’s discussion with Martin Heidegger in The ordeal of Truth, published in Foundations of Science 2020. It appreciates Stiegler’s progressive reading of Heidegger’s work but critically reflects on several elements in his work. A first element is the methodological aspect of Heidegger’s being historical thinking, which is missed by Stiegler and confirms the indifference towards philosophical method that can be found in the work of many contemporary philosophers. A second element concerns Heidegger’s and Stiegler’s (...) remaining humanism and the necessity to move beyond humanism and post-humanism in the era of global warming. A third element of reflection concerns Stiegler’s idea of the obligation of making our being-in-default come true, which shows a hidden metaphysical orientation in his work. (shrink)

Discussion on God's knowledge, awareness of God with people though are different, but still closely related. This article talks about God's knowledge, although knowledge of God and the people, but not for the medieval Shengboerna the so-called "secular knowledge" and "God of knowledge" distinction; this will only be God's own knowledge or wisdom, philosophical discussion. First, the paper will compare the start, mainly related to the so-called Fozhi Buddhism and Western philosophers such as Aristotle,圣多瑪斯, Hegel and others about God, know (...) God, absolute spirit of the discussion, especially圣多瑪斯discussion on knowledge of God, compare, and summarize them are focused on comprehensive and complete self-conscious, and of all things and the universal and the individual's knowledge. Then, this paper will further discuss whether it contains the narrative of God to know the ingredients, that is God for individuals and groups in the body of the story or may occur, actual and imagined the story of building awareness. In short, my book can only be regarded as restricted view up to see. Both for Glimpse, then it is limited, should be able to break the world's big pipe to significantly; both for the discussion, it should be deconstructed in order to display the infinite Creator. The discussion of "Scientia Dei " is very much related to, though still different from, the question "Quomodo Deus a nobis cognoscatur ." This paper deals with Scientia Dei, not in the sense it is distinguished from Scientia Mundi by St Bernard of Clairvaux, but in the sense it is related to all philosophical discourses on the wisdom of God Himself. The first step of this paper is a comparative study with "Buddha's Wisdom" taught by some major Mahayana Buddhist Schools, and the ideas of God, God's Knowledge and Absolute Spirit in Aristotle, St. Thomas and Hegel, in particular St. Thomas' discussion of "Scientia Dei." The result of this comparison is their common emphasis on God's total and complete transparent self-understanding, and His universal and concrete knowledge of all things. After this, we will move on to discuss the narrative component of Scientia Dei, to see whether in God's knowledge there is a place for the historical and imaginative stories of all social groups and individuals, of their inexhaustible possibilities, developments and constructions, both descriptive and imaginative. Anyhow, this essay is limited to a comparative and discursive study, without any ground in the author's religious experience with God's knowledge. Therefore it should be deconstructed once it is pronounced, erased once it is written. (shrink)

La décade de Cerisy Gilbert Simondon ou l'invention du futur a rassemblé des philosophes tels que Jean-Hugues Barthélémy, Andrew Feenberg ou Bernard Stiegler, des chercheurs venus d'autres disciplines, tels qu'Armand Hatchuel, Gilles Cohen-Tannoudji ou Thierry Gaudin, et toute une génération de jeunes chercheurs. Il en résulte un livre foisonnant où l'astrophysique côtoie la psychothérapie, où l'architecture dialogue avec l'informatique, et où tous ces savoirs tendent vers une communication encyclopédique. Il débute avec les "transductions politiques de Simondon" pour penser la (...) relation entre les évolutions technologiques et les normativités sociales. Puis, il aborde "la techno-esthétique" et le design, frayant la voie à une esthétique interne à la réalité technique qui ne repose plus sur la contemplation mais sur la participation à la technicité. Avec la "culture technologique", il est question des techniques à l'échelle du nanomètre et des instruments astronomiques spatiaux, qui imposent à la Culture d'intégrer les schèmes de la communication entre échelles. Le quatrième volet, consacré au "préindividuel quantique", propose une ré-interprétation de la mécanique quantique fondée sur les notions de préindividualité, de potentialité et de phases. "L'information et les réseaux", leurs enjeux, sont ensuite étudiés en relation avec l'informatique et les TIC. Ces technologies conditionnant aussi l'individuation psychique et collective, l'enquête se prolonge en direction du "sens du transindividuel". Enfin, ce cycle de réflexions s'achève sur "une philosophie en devenir" et les interventions esquissant des lignes d'évolution possibles pour la philosophie de Simondon. Premier jalon dans l'internationalisation des études simondoniennes, cet ouvrage propose une perspective résolument orientée vers l'invention du futur."--Page 4 of cover. (shrink)

The paper centres on a particular pattern of argument in Bernard Bosanquet aesthetic writings. This pattern is one which has roots in a more general Idealist response to Kant's formulation of the problem of aesthetic judgment. In other words, it has roots in thinkers such as Schiller, Schelling and Hegel. The core of the pattern of argument concentrates on the relation, in both artistic production and contemplation, between reason and sensuousness and form and content. The paper tries to show (...) how Bosanquet, in formulating his aesthetic theory, fashions his argument into what I call a 'social aesthetic'. He is helped in this process of formulating a 'social aesthetic' by subtly linking his Hegelian-based arguments with the ideas of both William Morris and John Ruskin. Throughout the paper the various arguments revolve therefore around the central relation of reason and sensuousness and form and content. (shrink)

In this paper, we carry out a critical analysis of the concept of technology in the current design of the bio-based economy (BBE). Looking at the current status of the BBE, we observe a dominant focus on technological innovation as the principal solution to climatic instability. We take a critical stance towards this “ecomodernist” worldview, addressing its fundamental assumptions, and ofer an underarticulated explanation as to why a successful transition toward a sustainable BBE—i.e. one that fully operates within the Earth’s (...) carrying capacity—has not yet been reached. Bernard Stiegler has developed a philosophical perspective on the concept of economy, broadening it to include the human condition through the notion of desire. This theory can help to obtain a more profound understanding of why ecomodernist strategies are dominant today. Stiegler’s theory of the libidinal economy ofers an analysis of controlled and exploited human desire as a primary driver behind modern techno-economic structures. Our hypothesis is that a critique of contemporary technofxism as a critique of libidinal economy is a necessary step to take in the discussion around the BBE as a concept, if the BBE is ever to bring about a system that can truly operate within the Earth’s carrying capacity.

The point of departure of this article is the trend towards hybridisation in new technology development, which makes classical dichotomies between machines, human life and the environment obsolete and leads to the post-human world we live in today. We critically reflect on the post-human concept of the hybrid world. Although we agree with post-humanists that human life can no longer be opposed to machines but appears as a decentralized human-technology relation, alliance or network that constitutes a hybrid world, we ask (...) for a limit to hybridisation. After rejecting the concept of metabolism as such a limit, we explore the concept of the responsive conativity of material entities. The principle of conativity of material entities provides a materialist perspective on metabolism, which enables us to conceive material entities as self-assertive material entities that are differentiated from the environment. The principle of responsivity of material entities provides a materialist perspective on the post-human world in which material entities are responsive to each other and form alliances and networks. We propose to differentiate between the conativity and responsivity of material entities and propose the conativity of matter as a limit to hybridisation in the post-human world. (shrink)

This book closely examines our commonly held beliefs about human suffering, and offers unique insights into God's role in why we suffer. Dr. Perri critically examines what it means to be human from a Judeo-Christian perspective, and extrapolates from the work of Carl Gustav Jung showing a deeply complex development of human transcendence in human suffering. On an interpersonal level, Dr. Perri elaborates on the work of Martin Buber and Emanuel Levinas and shows how our suffering can be shared and (...) lessened by our unconditionality and presence for the other. Scriptural passages are quoted from both the Hebrew and New Testament texts, and are used to depict the suffering of humankind as seen in the face of Job. It was this face, according to Perri, that Jesus saw in the faces of those He came to redeem, and that ultimately brought Him to the crucifix of redemption. Dr. Perri challenges Sartre's position that our existence precedes our essence, and draws on the work of Abraham Joshua Heschel and Christian theology in this regard. He further elaborates a neurodevelopmental paradigm that creates essence as the basis of our freedom to choose. This book can be read and studied by both professionals in the helping and healing professions, and lay persons seeking to better understand our suffering, and how to better help those who suffer. Dr. Perri offers specific ways in how to be present for those who suffer, how to read and receive the hidden language of human suffering, and how to use silence as a communication skill. (shrink)

In this paper it is argued that existing ‘self-representational’ theories of phenomenal consciousness do not adequately address the problem of higher-order misrepresentation. Drawing a page from the phenomenal concepts literature, a novel self-representational account is introduced that does. This is the quotational theory of phenomenal consciousness, according to which the higher-order component of a conscious state is constituted by the quotational component of a quotational phenomenal concept. According to the quotational theory of consciousness, phenomenal concepts help to account for the (...) very nature of phenomenally conscious states. Thus, the paper integrates two largely distinct explanatory projects in the field of consciousness studies: (i) the project of explaining how we think about our phenomenally conscious states, and (ii) the project of explaining what phenomenally conscious states are in the first place.

With a new foreword by Jonathan Lear 'Remarkably lively and enjoyable…It is a very rich book, containing excellent descriptions of a variety of moral theories, and innumerable and often witty observations on topics encountered on the way.' -_ Times Literary Supplement_ Bernard Williams was one of the greatest philosophers of his generation. Ethics and the Limits of Philosophy is not only widely acknowledged to be his most important book, but also hailed a contemporary classic of moral philosophy. Drawing on (...) the ideas of the Greek philosophers, Williams reorients ethics away from a preoccupation with universal moral theories towards ‘truth, truthfulness and the meaning of an individual life’. He explores and reflects upon the most difficult problems in contemporary philosophy and identifies new ideas about central issues such as relativism, objectivity and the possibility of ethical knowledge. This edition also includes a commentary on the text by A.W.Moore. At the time of his death in 2003, Bernard Williams was hailed by the Times as 'the outstanding moral philosopher of his age.' He taught at the Universities of Cambridge, Berkeley and Oxford and is the author of many influential books, including _Morality; Descartes: The Project of Pure Enquiry_ and _Truth and Truthfulness_.

This paper investigates the prospects of Rodney Brooks’ proposal for AI without representation. It turns out that the supposedly characteristic features of “new AI” (embodiment, situatedness, absence of reasoning, and absence of representation) are all present in conventional systems: “New AI” is just like old AI. Brooks proposal boils down to the architectural rejection of central control in intelligent agents—Which, however, turns out to be crucial. Some of more recent cognitive science suggests that we might do well to dispose of (...) the image of intelligent agents as central representation processors. If this paradigm shift is achieved, Brooks’ proposal for cognition without representation appears promising for full-blown intelligent agents—Though not for conscious agents. (shrink)

Will future lethal autonomous weapon systems (LAWS), or ‘killer robots’, be a threat to humanity? The European Parliament has called for a moratorium or ban of LAWS; the ‘Contracting Parties to the Geneva Convention at the United Nations’ are presently discussing such a ban, which is supported by the great majority of writers and campaigners on the issue. However, the main arguments in favour of a ban are unsound. LAWS do not support extrajudicial killings, they do not take responsibility away (...) from humans; in fact they increase the abil-ity to hold humans accountable for war crimes. Using LAWS in war would probably reduce human suffering overall. Finally, the availability of LAWS would probably not increase the probability of war or other lethal conflict—especially as compared to extant remote-controlled weapons. The widespread fear of killer robots is unfounded: They are probably good news. (shrink)

Traditionally, discussions of moral participation – and in particular moral agency – have focused on fully formed human actors. There has been some interest in the development of morality in humans, as well as interest in cultural differences when it comes to moral practices, commitments, and actions. However, until relatively recently, there has been little focus on the possibility that nonhuman animals have any role to play in morality, save being the objects of moral concern. Moreover, when nonhuman cases are (...) considered as evidence of moral agency or subjecthood, there has been an anthropocentric tendency to focus on those behaviors that inform our attributions of moral agency to humans. For example, some argue that the ability to evaluate the principles upon which a moral norm is grounded is required for full moral agency. Certainly, if a moral agent must understand what makes an action right or wrong, then most nonhuman animals would not qualify (and perhaps some humans too). However, if we are to understand the evolution of moral psychology and moral practice, we need to turn our attention to the foundations of full moral agency. We must first pay attention to the more broadly normative practices of other animals. Here, we begin that project by considering evidence that great apes and cetaceans participate in normative practices. (shrink)

In the mid twentieth century the philosopher Ludwig Wittgenstein famously asserted that games are indefinable; there are no common threads that link them all. "Nonsense," says the sensible Bernard Suits: "playing a game is a voluntary attempt to overcome unnecessary obstacles." The short book Suits wrote demonstrating precisely that is as playful as it is insightful, as stimulating as it is delightful. Suits not only argues that games can be meaningfully defined; he also suggests that playing games is a (...) central part of the ideal of human existence, so games belong at the heart of any vision of Utopia. Originally published in 1978, The Grasshopper is now re-issued with a new introduction by Thomas Hurka and with additional material (much of it previously unpublished) by the author, in which he expands on the ideas put forward in The Grasshopper and answers some questions that have been raised by critics.

How I became a philosopher -- To love, to love me, to love us.

We tend to suppose that the ancient Greeks had primitive ideas of the self, of responsibility, freedom, and shame, and that now humanity has advanced from these to a more refined moral consciousness. Bernard Williams's original and radical book questions this picture of Western history. While we are in many ways different from the Greeks, Williams claims that the differences are not to be traced to a shift in these basic conceptions of ethical life. We are more like the (...) ancients than we are prepared to acknowledge, and only when this is understood can we properly grasp our most important differences from them, such as our rejection of slavery. The author is a philosopher, but much of his book is directed to writers such as Homer and the tragedians, whom he discusses as poets and not just as materials for philosophy. At the center of his study is the question of how we can understand Greek tragedy at all, when its world is so far from ours. Williams explains how it is that when the ancients speak, they do not merely tell us about themselves, but about ourselves. _Shame and Necessity_ gives a new account of our relations to the Greeks, and helps us to see what ethical ideas we need in order to live in the modern world.

Artificial intelligence (AI) is a digital technology that will be of major importance for the development of humanity in the near future. AI has raised fundamental questions about what we should do with such systems, what the systems themselves should do, what risks they involve and how we can control these. - After the background to the field (1), this article introduces the main debates (2), first on ethical issues that arise with AI systems as objects, i.e. tools made and (...) used by humans; here, the main sections are privacy (2.1), manipulation (2.2), opacity (2.3), bias (2.4), autonomy & responsibility (2.6) and the singularity (2.7). Then we look at AI systems as subjects, i.e. when ethics is for the AI systems themselves in machine ethics (2.8.) and artificial moral agency (2.9). Finally we look at future developments and the concept of AI (3). For each section within these themes, we provide a general explanation of the ethical issues, we outline existing positions and arguments, then we analyse how this plays out with current technologies and finally what policy conse-quences may be drawn.

It used to be that everyone read the "notorious" Bernard Mandeville (1670-1733). He was a great satirist and come to have a profound impact on economics, ethics and social philosophy. "The Fable of the Bees" begins with a poem and continues with a number of essays and dialogues. It is all tied together by the startling and original idea that "private vices" (self-interest) lead to "publick benefits" (the development and operation of society).

Bernard Williams's remarkable essay on morality confronts the problems of writing moral philosophy, and offers a stimulating alternative to more systematic accounts which seem nevertheless to have left all the important issues somewhere off the page. Williams explains, analyses and distinguishes a number of key positions, from the purely amoral to notions of subjective or relative morality, testing their coherence before going on to explore the nature of 'goodness' in relation to responsibilities and choice, roles, standards, and human nature. (...) The final chapters make a fascinating enquiry into what morality is about, looking beyond happiness to other human aims and ideals. This re-issue of a classic in moral philosophy includes a new foreword by the author. (shrink)

In recent years, Charles Sanders Peirce has emerged, in the eyes of philosophers both in America and abroad, as one of America’s major philosophical thinkers. His work has forced us back to philosophical reflection about those basic issues that inevitably confront us as human beings, especially in an age of science. Peirce’s concern for experience, for what is actually encountered, means that his philosophy, even in its most technical aspects, forms a reflective commentary on actual life and on the world (...) in which it is lived. In Charles S. Peirce: On Norms and Ideals, Potter argues that Peirce’s doctrine of the normative sciences is essential to his pragmatism. No part of Peirce’s philosophy is bolder than his attempt to establish esthetics, ethics, and logic as the three normative sciences and to argue for the priority of esthetics among the trio. Logic, Potter cites, is normative because it governs thought and aims at truth; ethics is normative because it analyzes the ends to which thought should be directed; esthetics is normative and fundamental because it considers what it means to be an end of something good in itself. This study shows that pierce took seriously the trinity of normative sciences and demonstrates that these categories apply both to the conduct of man and to the workings of the cosmos. Professor Potter combines sympathetic and informed exposition with straightforward criticism and he deals in a sensible manner with the gaps and inconsistencies in Peirce’s thought. His study shows that Peirce was above all a cosmological and ontological thinker, one who combined science both as a method and as result with a conception of reasonable actions to form a comprehensive theory of reality. Peirce’s pragmatism, although it has to do with "action and the achievement of results, is not a glorification of action but rather a theory of the dynamic nature of things in which the "ideal" dimension of reality – laws, nature of things, tendencies, and ends – has genuine power for directing the cosmic order, including man, toward reasonable goals.

" Façonner le monde atome par atome " : tel est l'objectif incroyablement ambitieux affiché par les promoteurs américains de la " National Nanoinitiative ", lancée en 1999. Un projet global de " convergence des sciences ", visant à " initier une nouvelle Renaissance, incorporant une conception holiste de la technologie fondée sur [..] une analyse causale du monde physique, unifiée depuis l'échelle nano jusqu'à l'échelle planétaire. " Ce projet démiurgique est aujourd'hui au coeur de ce qu'on appelle la " (...) technoscience ", étendard pour certains, repoussoir pour d'autres. En précisant dans ce livre la signification de ce concept, pour sortir enfin du sempiternel conflit entre technophiles et technophobes, son auteur propose d'abord une sorte d'archéologie du terme " technoscience ". Loin d'être un simple renversement de hiérarchie entre science et technique, il s'agit d'un changement de régime de la connaissance scientifique, ayant désormais intégré la logique entrepreneuriale du monde des affaires et mobilisant des moyens considérables. Surtout, Bernadette Bensaude-Vincent montre que le brouillage de la frontière entre science et technique n'est que la manifestation d'un tremblement plus général, marqué par l'effacement progressif des distinctions traditionnelles : nature/artifice, inerte/vivant, matière/esprit, homme/machine, etc. Alors que nos sociétés sont silencieusement reconfigurées par les nanotechnologies, Internet, le génie génétique ou les OGM, ce livre montre l'importance de faire enfin pleinement entrer les questions de choix technologiques et scientifiques dans la sphère du politique et dans l'arène publique. Car la technoscience est un processus historique qui engage la nature en la refaçonnant et qui implique la société dans son ensemble. (shrink)

Recent studies have shown that self‐explanation is an effective metacognitive strategy, but how can it be leveraged to improve students' learning in actual classrooms? How do instructional treatments that emphasizes self‐explanation affect students' learning, as compared to other instructional treatments? We investigated whether self‐explanation can be scaffolded effectively in a classroom environment using a Cognitive Tutor, which is intelligent instructional software that supports guided learning by doing. In two classroom experiments, we found that students who explained their steps during problem‐solving (...) practice with a Cognitive Tutor learned with greater understanding compared to students who did not explain steps. The explainers better explained their solutions steps and were more successful on transfer problems. We interpret these results as follows: By engaging in explanation, students acquired better‐integrated visual and verbal declarative knowledge and acquired less shallow procedural knowledge. The research demonstrates that the benefits of self‐explanation can be achieved in a relatively simple computer‐based approach that scales well for classroom use. (shrink)

Conceptual Foundations of Quantum Mechanics provides a detailed view of the conceptual foundations and problems of quantum physics, and a clear and comprehensive account of the fundamental physical implications of the quantum formalism. This book deals with nonseparability, hidden variable theories, measurement theories and several related problems. Mathematical arguments are presented with an emphasis on simple but adequately representative cases. The conclusion incorporates a description of a set of relationships and concepts that could compose a legitimate view of the world.
