What is life? For four centuries, it has been believed that the only possible scientific approach to this question proceeds from the Cartesian metaphor -- organism as machine. Therefore, organisms are to be studied and characterized the same way "machines" are; the same way any inorganic system is. Robert Rosen argues that such a view is neither necessary nor sufficient to answer the question. He asserts that life is not a specialization of mechanism, but rather a sweeping generalization (...) of it. Above all, Rosen argues that renouncing mechanism does not mean abandoning science. A radical alternative is proposed, drawn equally from experience in biology, physics, and mathematics; an alternative which draws attention to a new class of complex systems, which are radically different from mechanism.

The present era of biological annihilation lends significant urgency to the need to radically reconfigure human-animal-nature relations along more ethical lines and sustainable trajectories. This article engages with largely post-humanist scholarship to offer up an in-depth qualitative analysis of a set of semi-structured interviews, conducted in August 2017-2018 with 26 radical environmental activists (REAs) from a variety of movements. These activists are posited as contemporary manifestations of the 'post-anthropocentric paradigm shifts' that challenge traditional notions of human separateness from - and (...) superiority to - the nonhuman world. However, despite being broadly categorised as post-humanist or post-anthropocentric in their efforts to deconstruct hierarchical and dualistic constructions of the human-animal-nature relationship, considerable variations abound in terms of who and what REAs value and on what basis. The article concludes with a brief discussion of the nature of REAs' post-anthropocentric sensibilities and mobilisations, and considers implications for the development of more ethical modes of human-animal-nature relationality that value and respect the irreducible alterity of nonhuman others.

Compiling twenty articles on the nature of life and on the objective of the natural sciences, this remarkable book complements Robert Rosen's groundbreaking Life Itself--a work that influenced a wide range of philosophers, biologists, linguists, and social scientists. In Essays on Life Itself, Rosen takes to task the central objective of the natural sciences, calling into question the attempt to create objectivity in a subjective world and forcing us to reconsider where science can lead us (...) in the years to come.

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

A. H. Louie's More Than Life Itself is an exploratory journey in relational biology, a study of life in terms of the organization of entailment relations in living systems. This book represents a synergy of the mathematical theories of categories, lattices, and modelling, and the result is a synthetic biology that provides a characterization of life. Biology extends physics. Life is not a specialization of mechanism, but an expansive generalization of it. Organisms and machines share (...) some common features, but organisms are not machines. Life is defined by a relational closure that places it beyond the reach of physicochemical and mechanistic dogma, outside the reductionistic universe, and into the realm of impredicativity. Function dictates structure. Complexity brings forth living beings. (shrink)

This essay asks about the return to nature and “life itself” in contemporary feminist philosophy and theory, from the new materialisms to feminist science studies to environmental ethics and critical animal studies. Unlike traditional naturalisms, the contemporary turn to nature is explicitly posthumanist. Shifting their focus away from anti-essentialist critiques of woman-as-nature, these new feminist philosophies of nature have turned toward nonhuman animals, the cosmos, the climate, and life itself as objects of ethical concern. Drawing on (...) Foucault, the essay probes the ethical meanings of the term “life itself” invoked in many of these renaturalizing projects. Focusing especially on the archival matter that guides Foucault’s thinking, I suggest that we rethink “life itself” not as a transhistorical substance but as the unstable materiality of history. I then reframe Foucault’s archival, genealogical perspective through the lens of the Anthropocene and geological time. Reconceiving our archive as a fossil record, I suggest that Foucault has much to contribute to environmental challenges to human exceptionalism and the anthropogenic destruction of other species and ourselves.

This article deals with military honour in nineteenth-century Spain, after first examining how the meaning of this term evolved from the revolutionary Napoleonic wars onwards. This highly important moral value was learnt from the moment someone joined the army, and even before then, through education and common public military demonstrations. It related to individual behaviour, while also maintaining a high collective and corporative aspect, and it varied depending on gender or class and on the identity of the social group. It (...) was part of the political thought of most relevant Spanish generals, and consequently it influenced the political dynamics of Spain. The Court of Honour, an institution in Spain that was not regulated until 1811, controlled honour compliance. The last section of this article focuses on how and why these institutions were born and explains their early legislative evolution. Spanish political and military development are inevitably bound together to the extent that an understanding of the nature of honour and its effects on the army and civilian ethics provides us with a deep socio-political and ethical analysis of the country during the nineteenth century.

The emerging concept of systems medicine (or ‘P4 medicine’—predictive, preventive, personalized and participatory) is at the vanguard of the post-genomic movement towards ‘precision medicine’. It is the medical application of systems biology, the biological study of wholes. Of particular interest, P4 systems medicine is currently promised as a revolutionary new biomedical approach that is holistic rather than reductionist. This article analyzes its concept of holism, both with regard to methods and conceptualization of health and disease. Rather than representing a medical (...) holism associated with basic humanistic ideas, we find a technoscientific holism resulting from altered technological and theoretical circumstances in biology. We argue that this holism, which is aimed at disease prevention and health optimization, points towards an expanded form of medicalization, which we call ‘holistic medicalization’: Each person’s whole life process is defined in biomedical, technoscientific terms as quantifiable and controllable and underlain a regime of medical control that is holistic in that it is all-encompassing. It is directed at all levels of functioning, from the molecular to the social, continual throughout life and aimed at managing the whole continuum from cure of disease to optimization of health. We argue that this medicalization is a very concrete materialization of a broader trend in medicine and society, which we call ‘the medicalization of health and life itself’. We explicate this holistic medicalization, discuss potential harms and conclude by calling for preventive measures aimed at avoiding eventual harmful effects of overmedicalization in systems medicine (quaternary prevention).

With a novel approach to Aristotle's zoology, this study looks at animals as creatures of nature and reveals a scientific discourse that, in response to his predecessors, exiles logos as reason and pursues the logos intrinsic to animals' bodies empowering them to sense the world and live. The volume explores Aristotle's conception of animals through a discussion of his ad hoc methodology to study them, including the pertinence of the soul to such a study, and the rise of zoology as (...) a branch of natural philosophy. For Aristotle, animal life stems from the body in the space of existence and revolves around sensation, which is entwined with pleasure, pain, and desire. Lack of human reason is irrelevant to an understanding of the richness of animal life and cognition. In sum, the reader will acquire knowledge of the animal as such, which lay at the core of Aristotle's agenda and required a study of its own, separate from plants and the elements. This book is intended for students of history of science, ancient biology and philosophy and all those who, from different fields, are interested in animal studies and the human/animal relation.

The article argues for the relevance of Simmel's life‐philosophy for the contemporary thought about life and death. By considering life, paradoxically, at once as a pre‐individual flux of becoming and individuated, Simmel manages to avoid both reductionism and mysticism. In addition, unlike Deleuze, for example, Simmel thinks that we can experience and know life only in some individual, actual form, never in its pure virtuality, as an absolute flow. During the course of examination, Simmel's insights will (...) also be discussed in connection with Heidegger. The article maintains that what remains on the Simmelian side beyond the striking affinities between the two thinkers is a kind of animal vitality. Though Simmel's life‐philosophy is mainly concerned with the world‐relation of humans, when it comes to death, it places humans on a par with all living organisms. A death that is immanent in life is appropriate to anything that is living. Thus the human individual, too, is dying precisely as a living organism, as some‐body that is alive. (shrink)

This essay is an attempt to construct an artificial dialog loosely modeled after that sought by Robert Maynard Hutchins who was a significant influence on many of us including and especially Robert Rosen. The dialog is needed to counter the deep and devastating effects of Cartesian reductionism on today’s world. The success of such a dialog is made more probable thanks to the recent book by A. Louie. This book makes a rigorous basis for a new paradigm, the one pioneered (...) by the late Robert Rosen. If we are to make such a paradigm shift happen, it has to be in the spirit of the dialog. The relationship between science, economics, technology and politics has to be openly recognized and dealt with. The message that Rosen sent to us has to be told outside small select circles of devotees. The situation has even been described by some as resembling a cult. This is no way for universal truths like these to be seen. The essay examines why this present situation has happened and identifies the systemic nature of the problem in terms of Rosen’s concepts about systems. The dialog involves works by George Lakoff, W. Brian Arthur, N. Katherine Hayles, Robert Reich and Dorion Sagan. These scholars each have their own approach to identifying the nature of the interacting systems that involve human activity and the importance of identifying levels of abstraction in analyzing systems. Pooling their insights into different facets of a complex system is very useful in constructing a model of the self referential system that humans and their technology have shaped. The role of the human component in the whole earth system is the goal of the analysis. The impact of the Cartesian reductionist paradigm on science and the related aspects of human activity are examined to establish an explanation for the isolation of Rosen’s paradigm. The possible way to proceed is examined in the conclusion. (shrink)

This paper examines a dilemma within the Confucian tradition wherein one is forced to choose between upholding moral virtue and preserving one's own life. The mainstream view valorises and exalts the act of sacrificing one's life in order to uphold moral virtue. There are many supporters of this view, spanning across different periods, including but not limited to Confucius, Mencius, the Cheng brothers, Zhu Xi, and so on. There is, however, an opposing voice within the Confucian tradition. Wang (...) Gen, a Neo-Confucian thinker and founder of the Taizhou School of thought, opposes the mainstream position by arguing for the primacy of life and against the glorification of these acts of sacrifice. This paper has two aims. The first aim is to trace the development of the mainstream view within the Confucian tradition. The second aim investigates how Wang Gen argues against the mainstream position whilst situating himself within the Confucian tradition. (shrink)

This article discusses a case in this issue of The Journal of Clinical Ethics by McCrary and colleagues, “Elective Delivery Before 39 Weeks’ Gestation Reconciling Maternal, Fetal, and Family Circumstances,” in which parents asked the medical team to deliver their fetus “early.” The author discusses (1) the importance that parents have to a child when they are able to love the child, and how important it is for decision makers to consider this; (2) exceptional approaches that may enable parents to (...) “change their minds”; and (3) substantive and procedural innovations that may help to prevent clinicians’ views from playing too big a role and/or being arbitrary. The author concludes by describing how he felt when reading the case and uses this to illustrate how clinicians may benefit by assessing their feelings. (shrink)

We review and discuss A. H. Louie’s book “More than Life Itself: A Reflexion on Formal Systems and Biology” from an interdisciplinary viewpoint, involving both biology and mathematics, taking into account new developments and related theories.

The presence of a human being/organism—a living human ‘whole’, with the defining tendency to promote its own welfare—has value in itself, as do the functions which compose it. Life is inseparable from health, since without some degree of healthy functionality the living whole would not exist. The value of life differs both within a single life and between lives. As with any other form of human flourishing, the value of life-and-health must be distinguished from the (...) moral importance of human beings: less fulfilled means not less important morally, but more in need of being fulfilled. That said, to say that life and health has value is not to say exactly what—if anything—that value requires by way of active promotion at a given time. Many factors must be taken into account in making health care decisions, even if the worth of all lives, and the dignity of all human beings, must in every case be acknowledged. (shrink)

This is the introductory essay to the special edition of 'Cosmos & History' focusing on the question 'What is Life?'.

I discuss "Poetic Naturalism" -- there is only one world, the natural world, but there are many ways of talking about it -- both as a general concept, and how it accounts for our actual world. I talk about emergence, fundamental physics, entropy and complexity, the origins of life and consciousness, and moral constructivism.

In this paper, I discuss Karen Ng's reconstruction of Hegel's concept of life. On Ng's account, Hegel's conception of life has a remarkable double role to play: Life is both the proper object of judgment as well as a fundamental characterization of the activity of the judging subject. In a first step, I highlight the insight that Ng's account sheds on the internal connection of life and self-consciousness and the peculiar normativity of life. In a (...) second step, I raise three concerns about Ng's strong focus on the logical notion of life which she characterizes as non-empirical and a priori. I argue that in order to uncover the full significance of the notion of life for Hegel we have to turn to his Philosophy of Nature and Spirit. (shrink)

To date, no definition of life has been unequivocally accepted by the scientific community. In frustration, some authors advocate alternatives to standard definitions. These include using a list of characteristic features, focusing on life’s effects, or categorizing biospheres rather than life itself; treating life as a fuzzy category, a process or a cluster of contingent properties; or advocating a ‘wait-and-see’ approach until other examples of life are created or discovered. But these skeptical, operational, and (...) pluralistic approaches have intensified the debate, rather than settled it. Given the failure of even these approaches, we advocate a new strategy. In this paper, we reverse the usual line of reasoning and argue that the “life problem” arises from thinking incorrectly about the nature of life. Scientists most often conceptualize life as a class or kind, with earthly life as a single instance of it. Instead, we advocate thinking about Earth’s Life as an individual, in the way that species are now thought to be. In this view, Life is a monophyletic clade that originated with a last universal common ancestor, and includes all its descendants. We can continue to use the category ‘life’ pragmatically to refer to similarities between various phenomena and Life. But the relevant similarities are a matter of interest and preference, not a matter of fact. The search for other life in the Universe, then, is merely a search for entities that resemble parts of Life in whatever sense astrobiologists find most appealing. This does not mean that the search for evolved complexity elsewhere in the universe or its creation in the lab are futile endeavors, but that debates over whether they count as ‘life’ are. Ironically, finally abandoning the concept ‘life’ may make our searches for evolved complexity more fruitful. We explain why. (shrink)

This book is an account of the philosophical movement named Lebensphilosophie, which flourished at the end of the 19th and the beginning of the 20th century. There many philosophers who participated in the movement, but this book concentrates on the three most important: Friedrich Nietzsche, Wilhelm Dilthey and Georg Simmel. The movement was called Lebensphilosophie—literally, philosophy of life—because its main interest was not life as a biological phenomenon but life as it is lived by human beings. They (...) regarded human life and experience as the fundamental reality, the basis of all knowledge and value, and disputed the relevance of any supernatural realm transcending human experience. The purpose of life was therefore life itself. Lebensphilosophie was the first modern philosophical movement in the Western tradition. It was “modern” in the sense that it was entirely humanist and secular, deriving all values from a non-religious perspective. Nietzsche, Dilthey and Simmel were either atheists or agnostics; they denied the relevance of any transcendent reality or being for human life. They abjured the traditional Christian concern with salvation and immortality. They also disputed the existence of natural law, teleology or a providential order; human beings created their own values and they did not conform to any made by nature. In anticipation of later existentialism, the Lebensphilosophen maintained that human beings are the makers of their own fate. Contrary to pessimism, they affirmed the great value of life while still acknowledging its frequent tragedy. The Lebensphilosophen were champions of an individualist ethics, which maintained that the highest good for a human being was self-realization, the development of a persons’s unique individuality. Their ethics was neither utilitarian nor de-ontological: it was not utilitarian because it did not regard the highest good as pleasure; self-realization could be a very unpleasant experience; and it was not de-ontological because it grounded moral norms upon the facts of human development and experience. The Lebensphilosophen were major advocates of historicism. They believed that human experience is formed by history, and that its horizons and limits are historical. Just as it was impossible to transcend human experience, so it was impossible to transcend history. All values and norms were therefore historical. In attempting to describe historical experience, the Lebensphilosophen developed the discipline of hermeneutics. They refused to accept mechanical explanation as a paradigm of explanation. This book attempts to describe and analyze the fundamental aspects of Lebensphilosophie by looking in detail at the views of its three leading figures. It examines their ethics, their religious background, their responses to pessimism and relativism, and their contributions to hermeneutics and historicism. (shrink)

In French, the verb "to live" designates both being alive and the experience of something. This ambiguity has a philosophical meaning. The task of a phenomenology of life is to describe an originary sense of living from which the very distinction between life in the intransitive sense and life in the transitive, or intentional, sense proceeds. Hans Jonas is one of those rare authors who has tried to give an account of the specificity of life instead (...) of reducing life to categories that are foreign to it. However, the concept of metabolism, by which Jonas characterizes vital activity, attests to a presupposition as to life: life is conceived as self-preservation, that is, as negation of death, in such a way that life is, in the end, not thought on the basis of itself. The aim of this article is to show that life as such must be understood as movement in a radicalized sense, in which the living being is no more the subject than the product. All living beings are in effect characterized by a movement, which nothing can cause to cease, a movement that largely exceeds what is required by the satisfaction of needs and that, because of this, bears witness to an essential incompleteness. This incompleteness reveals that life is originarily bound to a world. Because the world to which the living being relates is essentially non-totalizable and unpresentable, living movement can not essentially complete itself. Thus, in the final analysis, life must be defined as desire, and in virtue of this view, life does not tend toward self-preservation, as we have almost always thought, but toward the manifestation of the world.

The Internet has become a resource for everyone for everything. It is accordingly now also a source of sermons and much more for pastors of churches in the USA. In consequence, the Internet shapes and alters how pastors and parishioners practice their religion. Because “the medium is the message,” as Marshall McLuhan observed, Internet sermons necessarily reflect and convey something of their Internet source. So, too, the nature and content religious life changes and takes on the characteristics of its (...) new source of inspiration, the Internet. As the dominant expression of technology today, the Internet reveals technology ultimately and in the words of Jacques Ellul as “the real religion of our time.”. (shrink)

In the *Science of Logic*, Hegel states unequivocally that the category of “life” is a strictly logical, or pure, form of thinking. His treatment of actual life – i.e., that which empirically constitutes nature – arises first in his *Philosophy of Nature* when the logic is applied under the conditions of space and time. Nevertheless, many commentators find Hegel’s development of this category as a purely logical one especially difficult to accept. Indeed, they find this development only comprehensible (...) as long as one simultaneously assumes that Hegel breaks his promise to let the logic do the leading. However, if Hegel were to in fact allow the logical development to be led by biological analogies at this point, problems would ensue. Not only would it contradict his own speculative method, which should secure the necessity of the categories, but it would also endanger the ontological generality of the category of life itself. Beyond undermining his method and the logical integrity of the category, however, I will argue that such a reading makes the transition to the next category of “cognition” unintelligible and problematic. My aim in the first part of this paper is to argue how logical life can be read as a pure category. I then argue in the second part how my reconstruction makes the transition to cognition intelligible without resorting to profane or supernatural interpretations. (shrink)

This paper addresses an apparent tension between a familiar claim about meaning in general, to the effect that the meaning of anything owes to its place, ultimately, within a ‘form of life’, and a claim, also familiar, about the meaning of human life itself, to the effect that this must be something ‘beyond the human’. How can life itself be meaningful if meaning is a matter of a relationship to life? After elaborating and briefly (...) defending these two claims, two ways of amending and thereby reconciling them are considered and rejected. These ways involve either spiriting away the issue of life's meaning or encouraging unwelcome metaphysical views. The author then argues that, rather than remove the tension between the two claims, each should be viewed as expressing an aspect of a delicate metaphysical position. This position is distinguished from ones, like transcendental idealism and constructivism, with which it might be confused, and is then related to Daoist and Zen thought and to the later philosophy of Heidegger. Crucial to the position is the proposal that the ‘beyond the human’ which enables life to be meaningful is both ineffable and ‘intimate’ with life itself. (shrink)

This book demonstrates how and why vitalism—the idea that life cannot be explained by the principles of mechanism—matters now. Vitalism resists closure and reductionism in the life sciences while simultaneously addressing the object of life itself. The aim of this collection is to consider the questions that vitalism makes it possible to ask: questions about the role and status of life across the sciences, social sciences, and humanities and questions about contingency, indeterminacy, relationality and change. (...) All have special importance now, as the concepts of complexity, artificial life and artificial intelligence, information theory, and cybernetics become increasingly significant in more and more fields of activity.

In the future, human destiny may depend on our ethics. In particular, biotechnology and expansion in space can transform life, raising profound questions. Guidance may be found in Life-centered ethics, as biotic ethics that value the basic patterns of organic gene/protein life, and as panbiotic ethics that always seek to expand life. These life-centered principles can be based on scientific insights into the unique place of life in nature, and the biological unity of all (...) life. Belonging to life then implies a human purpose: to safeguard and propagate life. Expansion in space will advance this purpose but will also raise basic questions. Should we expand all life or only intelligent life? Should we aim to create populations of trillions? Should we seed other solar systems? How far can we change but still preserve the human species, and life itself? The future of all life may be in our hands, and it can depend on our guiding ethics whether life will fulfil its full potentials. Given such profound powers, life-centered ethics can best secure future generations. Our descendants may then understand nature more deeply, and seek to extend life indefinitely. In that future, our human existence can find a cosmic purpose. (shrink)

Some philosophers think that life is worth living not merely because of the goods and the bads within it, but also because life itself is good. I explain how this idea can be formalized by associating each version of such of a view with a function from length of life to the value generated by life itself. Then I argue that every version of the view that life itself is good faces some (...) version of the following dilemma: either (1) good human lives are worse than very long lives wholly devoid of pleasure, desire-satisfaction, knowledge, or any other goods, or (2) very short lives containing nothing but suffering are worth living. Since neither result is plausible, we ought to reject the view that life itself is good. On the view I favor, any given life may be worth living because of the goods that it contains, but life itself is neutral. (shrink)

Through a re-articulation of Derridean différance, Bernard Stiegler claims that the human is defined by an originary default that displaces all psychic and social life onto technical supplements. His philosophy of technics re-articulates the logic of the supplement as concerning both human reflexivity and its supports, and the history of the différance of life itself. This has been criticised for reducing Derrida's work to a metaphysics of presence, and for instituting a humanism of the relation to the (...) inorganic. By refuting these claims, this article will show that Stiegler's doubling of différance enables him to articulate the human as constituted by both the individuation characteristic of ‘life’, and that of a technical, psychic, and collective individuation. Putting forward a reading of the logic of the trace in life, and emphasising the aspects of Leroi-Gourhan, Simondon, and Canguilhem that Stiegler uses in his reading of Derrida, I will demonstrate that the political stakes of adaption and adoption in his Noopolitics require this re-articulation of différance. Technics shapes the human future, arising from this differential mutation; marking the invention of the human as the site of the political. (shrink)

In Humanity’s End: Why We Should Reject Radical Enhancement, Nicholas Agar presents a novel argument against the prospect of radical life-extension. Agar’s argument hinges on the claim that extended lifespans will result in people’s lives being dominated by the fear of death. Here we examine this claim and the surrounding issues in Agar’s discussion. We argue, firstly, that Agar’s view rests on empirically dubious assumptions about human rationality and attitudes to risk, and secondly, that even if those assumptions are (...) granted, the fears that Agar adverts to are unlikely to dominate people’s lives if and when radical life-extension is made possible. Further, we claim that the structure of the decision-making process around life-extension is unlikely to be the way that it would have to be in order for Agar’s claims about fear of death to make sense. Finally, we argue that Agar is implicitly committed to a narrow conception of human value. In response, we suggest that the pursuit of life-extension can itself be seen as an expression of certain important aspects of our distinctively human nature. (shrink)
