The Voice of Virtue illuminates the musical practices at the heart of the Neostoic movement that spread across French lands during the Wars of Religion in the latter half of the sixteenth century. Guided by twin reparative traditions granting music and philosophy therapeutic power, composers and performers across the embattled Catholic and Protestant confessions turned to moral song as a means of repairing personal and collective virtue damaged by the ongoing conflict. Moral song collections enlarged interest in Stoic philosophy by (...) circulating its ethical program to a broader audience through attractive paraphrases of Stoic maxims set to music. Even more importantly, this skillfully composed repertoire of polyphonic song offered a multi-sensory moral practice that would have resonated powerfully for those well-versed in the paradoxes of the Stoic tradition. Bringing together a repertoire of little-known music prints, a rich visual culture, and an impressive body of literary and philosophical sources, The Voice of Virtue not only illuminates the influence of Stoicism on music, but also reveals that we cannot fully understand Neostoicism as an intellectual or cultural movement without accounting for its vibrant musical sounds. Virtue, as voiced in these Stoic practices, proves to be both rational and fully invested in the sensory processes of the singing body. (shrink)

The Prince and the Wolf contains the transcript of a debate which took place on February 5, 2008 at the London School of Economics (LSE) between the prominent French sociologist, anthropologist, and philosopher Bruno Latour and the Cairo-based American philosopher Graham Harman.

In this book Bruno Latour brings together these different approaches to provide a lively and challenging analysis of science, demonstrating how social context..

Latour is a world famous and widely published French sociologist who has written with great eloquence and perception about the relationship between people, science, and technology. He is also closely associated with the school of thought known as Actor Network Theory. In this book he sets out for the first time in one place his own ideas about Actor Network Theory and its relevance to management and organization theory.

The emergence of modern sciences in the seventeenth century profoundly renewed our understanding of Nature. For the last three centuries new ideas of Nature have been continuously developed by theology, politics, economics, and science, especially the sciences of the material world. The situation is even more unstable today, now that we have entered an ecological mutation of unprecedented scale. Some call it the Anthropocene, but it is best described as a new climatic regime. And a new regime it certainly is, (...) since the many unexpected connections between human activity and the natural world oblige every one of us to reopen the earlier notions of Nature and redistribute what had been packed inside. So the question now arises: what will replace the old ways of looking at Nature? This book explores a potential candidate proposed by James Lovelock when he chose the name "Gaia" for the fragile, complex system through which living phenomena modify the Earth. The fact that he was immediately misunderstood proves simply that his readers have tried to fit this new notion into an older frame, transforming Gaia into a single organism, a kind of giant thermostat, some sort of New Age goddess, or even divine Providence. In this series of lectures on "natural religion", Bruno Latour argues that the complex and ambiguous figure of Gaia offers, on the contrary, an ideal way to disentangle the ethical, political, theological, and scientific aspects of the now obsolete notion of Nature. He lays the groundwork for a future collaboration among scientists, theologians, activists, and artists as they, and we, begin to adjust to the new climatic regime. (shrink)

Bruno Latour was once asked : "Do you believe in reality?" This text is an attempt to answer this question.

ABSTRACT Broome and others have argued that it makes no sense, or at least that it cannot be true, to say that it is better for a given person that he or she exist than not. That argument can be understood to suggest that, likewise, it makes no sense, or at least that it cannot be true, to say that it is worse for a given person that he or she exist than that he or she never have existed at (...) all. This argument is of critical importance to the question of whether consequentialist theory should take a traditional, aggregative form or a less conventional, person‐affecting, or person‐based, form. I believe that, potentially, the argument represents a far more serious threat to the person‐based approach than does, for example, Parfit's two medical programmes example. Parfit's example nicely illustrates the distinction between aggregative and person‐based approaches and raises important questions. But the example — though not, I think, by Parfit — is sometimes pressed into service as a full‐fledged counterexample against the person‐based approach. As such, I argue, the example is not persuasive. In contrast, the Broomeian argument, if correct, is definitive. For that argument relies on certain metaphysical assumptions and various uncontroversial normative claims — and hence nicely avoids putting into play the controversial normative claims that lie at the very heart of the debate. The purpose of the present paper, then, is to evaluate the Broomeian argument. I argue that this potentially definitive challenge to a person‐based approach does not in fact succeed. (shrink)

This book aims to give an account, called Variabilism, of the moral significance of merely possible persons and to use Variabilism to illuminate abortion. In doing so it lays the groundwork for a more productive discussion on abortion.

Stem cell biology and systems biology are two prominent new approaches to studying cell development. In stem cell biology, the predominant method is experimental manipulation of concrete cells and tissues. Systems biology, in contrast, emphasizes mathematical modeling of cellular systems. For scientists and philosophers interested in development, an important question arises: how should the two approaches relate? This essay proposes an answer, using the model of Waddington’s landscape to triangulate between stem cell and systems approaches. This simple abstract model represents (...) development as an undulating surface of hills and valleys. Originally constructed by C. H. Waddington to visually explicate an integrated theory of genetics, development and evolution, the landscape model can play an updated unificatory role. I examine this model’s structure, representational assumptions, and uses in all three contexts, and argue that explanations of cell development require both mathematical models and concrete experiments. On this view, the two approaches are interdependent, with mathematical models playing a crucial but circumscribed role in explanations of cell development. (shrink)

According to the Asymmetry, it is wrong to bring a miserable child into existence but permissible not to bring a happy child into existence. When it comes to procreation, we don’t have complete procreative liberty. But we do have some discretion. The Asymmetry seems highly intuitive. But a plausible account of the Asymmetry has been surprisingly difficult to provide, and it may well be that most moral philosophers – or at least most consequentialists – think that all reasonable efforts to (...) provide such an account have by now been exhausted. In this paper, I argue that, despite the difficulties, the Asymmetry is too important to be set aside. I also note a handful of accounts of the Asymmetry that have been proposed and why they fail. It seems, for example, that it will not do to say that some people matter morally and others don’t, or that a person matters morally in some worlds but not others. My own conclusion is that, while we are bound to say all people matter morally – you, me and the merely possible – we are not bound to say that all their losses– or all ours– matter morally. We can instead distinguish between morally significant and insignificant losses, with the distinction between the two being a matter of where the loss is incurred in relation to the person who incurs it. This way of looking at things – which I call Variabilism– provides the basis for a plausible account of the Asymmetry. The availability of such an account suggests, I think, that our prospects for rescuing the Asymmetry are bright. (shrink)

In a critical intervention into the bioethics debate over human enhancement, philosopher Melinda Hall tackles the claim that the expansion and development of human capacities is a moral obligation. Hall draws on French philosopher Michel Foucault to reveal and challenge the ways disability is central to the conversation. The Bioethics of Enhancement includes a close reading and analysis of the last century of enhancement thinking and contemporary transhumanist thinkers, the strongest promoters of the obligation to pursue enhancement technology. With (...) specific attention to the work of bioethicists Nick Bostrom and Julian Savulescu, the book challenges the rhetoric and strategies of enhancement thinking. These include the desire to transcend the body and decide who should live in future generations through emerging technologies such as genetic selection. Hall provides new analyses rethinking both the philosophy of enhancement and disability, arguing that enhancement should be a matter of social and political interventions, not genetic and biological interventions. Hall concludes that human vulnerability and difference should be cherished rather than extinguished. -/- This book will be of interest to academics working in bioethics and disability studies, along with those working in Continental philosophy (especially on Foucault).

There is by now broad consensus in the critical literature that neoliberalism and social conservatism have frequently coexisted in practice. Yet the alt-right fits none of the previously identified alliances: this is not the neoliberal neoconservatism of the Reagan and Bush years, nor the neoliberal communitarianism of the Third Way, nor even a form of neoliberal authoritarianism. Instead, the alt-right claims intellectual descent from economic libertarianism, on the one hand, and paleo- (as opposed to neo-) conservatism on the other. This (...) paper traces the contours of this ‘paleolibertarian’ alliance, first by following the volatile political trajectory of Murray Rothbard, the foremost philosopher of American libertarianism, and, second, by uncovering precedents in the longer history of the American far right. It will be argued that paleoconservatism makes for a uniquely powerful ally because it offers a workable response to libertarianism’s intrinsic contradictions. (shrink)

This essay examines the role of social interactions in the search for blood stem cells, in a recent episode of biomedical research. Linked to mid-20th century cell biology, genetics and radiation research, the search for blood stem cells coalesced in the 1960s and took a developmental turn in the late 1980s, with significant ramifications for immunology, stem cell and cancer biology. Like much contemporary biomedical research, this line of inquiry exhibits a complex social structure and includes several prominent scientific successes, (...) recognized as such by participating researchers. I use personal interviews and the published record to trace the social interactions crucial for scientific success in this episode. All recognized successes in this episode have two aspects: improved models of blood cell development, and new interfaces with other lines of research. The narrative of the search for blood stem cells thus yields a robust account of scientific success in practice, which generalizes to other scientific episodes and lends itself to expansion to include wider social contexts.

This paper examines a case of failed interdisciplinary collaboration, between experimental stem cell research and theoretical systems biology. Recently, two groups of theoretical biologists have proposed dynamical systems models as a basis for understanding stem cells and their distinctive capacities. Experimental stem cell biologists, whose work focuses on manipulation of concrete cells, tissues and organisms, have largely ignored these proposals. I argue that ‘failure to communicate’ in this case is rooted in divergent views of explanation: the theoretically-inclined modelers are committed (...) to a version of the covering-law view, while experimental stem cell biologists aim at mechanistic explanations. I propose a way to reconcile these two explanatory approaches to cell development, and discuss the significance of this result for interdisciplinary collaboration in systems biology and beyond.

The Asymmetry consists of two claims. (A) That a possible person's life would be abjectly miserable –less than worth living – counts against bringing that person into existence. But (B) that a distinct possible person's life would be worth living or even well worth living does not count in favour of bringing that person into existence. In recent years, the view that the two halves of the Asymmetry are jointly untenable has become increasingly entrenched. If we say all persons matter (...) morally whether they exist or not and on that basis try to explain the first half of the Asymmetry, we lose the second half of the Asymmetry. If we say that some persons do not matter morally and some do and on that basis try to explain the second half of the Asymmetry, we lose the first half of the Asymmetry – or else find ourselves with a principle that is either inconsistent or otherwise deeply troubled in some way that has nothing to do with the content of the Asymmetry itself. In this article, I propose an alternative approach to the Asymmetry which I will call Variabilism. By understanding each and every person, whether existing or not, to matter morally but variably– such that the moral significance of any loss incurred by any person is considered to depend, not on who incurs that loss and whether that person matters morally, but rather on where that loss is incurred in relation to the person who incurs it – we can both nicely ground the two halves of the Asymmetry and avoid the conceptual difficulties that have plagued competing approaches.

The non-identity problem is really a collection of problems having distinct logical features. For that reason, non-identity problems can be typed. This article focuses on just one type of non-identity problem, the problem, which includes Derek Parfit's depletion example and many others. The can't-expect-better problem uses an assessment about the low probability of any particular person's coming into existence to reason that an earlier wrong act does not harm that person. This article argues that that line of reasoning is unusually (...) treacherous in that it makes not just one hard-to-detect error in what is done with the relevant probability assessments but rather alternates between two. We sort out one fallacy only to fall, against all odds (as it were), into a second. By avoiding both errors, we become able to discern harm in cases in which the can't-expect-better problem argues there is none. We will then be in a position to set aside the can't-expect-better problem as an objection against the person-based intuition that acts that are must be at least some existing or future person.

Philosophical understanding of experimental scientific practice is impeded by disciplinary differences, notably that between philosophy and sociology of science. Severing the two limits the stock of philosophical case studies to narrowly circumscribed experimental episodes, centered on individual scientists or technologies. The complex relations between scientists and society that permeate experimental research are left unexamined. In consequence, experimental fields rich in social interactions have received only patchy attention from philosophers of science. This paper sketches a remedy for both the symptom and (...) its root cause. An empirical study of social interactions in an established field of biomedicine grounds a robust account of success in experimental practice. The core idea is the concept of collaboration, of participants working together on a common project toward a shared goal. The interactive social integument of experimental research is both examined and enacted in a study integrating socio-historical research and philosophical investigation. The two approaches are used in concert to explicate the concept of scientific objectivity. Their joint explication of this contested epistemic ideal demonstrates that philosophical and sociological approaches can work together toward a social epistemology of scientific practice. The explication is in three stages. First, a minimal framework for investigating collaborative activities is established. Social action is understood and evaluated in terms of the connection between shared goals that participants hope to accomplish together, and the coordinated means by which they try to do so. This connection is explicated as participation, a relation mediating between a group and its members, which includes minimal constraints of instrumental rationality. Second, this framework is fleshed out via empirical study of scientific practices. The focal case examines the intersection of immunology and stem cell research in mid-20th century biomedicine, tracing the key social interactions within and among laboratory groups, as the field of blood stem cell research emerged in the 1960s and advanced throughout the next four decades. The study yields a robust empirical result. Participants consistently recognize two aspects of scientific success: construction of improved models of blood cell development, and formation of new boundaries among scientific groups. In the third and final stage, this result is generalized to other experimental episodes and shown to fit with recent accounts of models in scientific practice. The generalized result approximates a familiar normative view of scientific knowledge. An epistemic ideal of scientific objectivity in practice is then derived from this robust general result, using the minimal constraints on rational participation. The derivation is analogous to specification of ends in moral philosophy; given the means taken and assuming some hope of success, what must the goal of scientific inquiry be like? The aim of science so conceived corresponds to a classic conception of scientific objectivity: knowledge independent of epistemic criteria specific to particular persons or groups. This result weaves together sociological and philosophical accounts of science, explicating the epistemic ideal of objectivity in relation to social aspects of scientific practice. This undercuts the entrenched dualism between normative, vs. descriptive approaches to scientific knowledge. Socio-historical study of science does not deflate, but vindicates, scientific objectivity. Philosophy and sociology are recast as collaborating participants in articulating social epistemology of science. (shrink)

In this paper, I propose a new way to integrate historical accounts of social interaction in scientific practice with philosophical examination of scientific knowledge. The relation between descriptive accounts of scientific practice, on the one hand, and normative accounts of scientific knowledge, on the other, is a vexed one. This vexatiousness is one instance of the gap between normative and descriptive domains. The general problem of the normative/descriptive divide takes striking and problematic form in the case of social aspects of (...) scientific knowledge. With respect to this issue, history and philosophy of science appear starkly incompatible. I show how this dualism can be overcome, drawing on social action theory and the recent history of cellular immunology. (shrink)

Just a decade ago, requests by students to establish groups to support gay and lesbian students were rare and generally met with shock and confusion by school administrators and local communities. Today there are more than 1600 gay straight alliances across the country._ Standing Out, Standing Together _documents the emergence of gay straight alliances in public schools across America - from factors that have contributed to the relatively rapid spread of GSA to those that stirred controversy and posed roadblocks. Using (...) over 10 years of interviews with students, teachers, administrators and political activists; case studies; and local and national media reports, Miceli explores the personal and political stakes involved in the battles over GSAs. Although the book acknowledges and documents the harassment, abuse and problems suffered by many gay, lesbian, transgendered, and bisexual students, its primary focus is on these students as political activists, rather than as passive victims, making it a unique contribution to sociologists, educators, political activists and LGBTreaders alike.

This paper focuses on a specific aspect of a Japanese rite of passage called Shichigosan. Although its origins go back to premodern Japan, its contemporary pattern truly reflects the modern living conditions of the Japanese. Today the ritual is one of the most popular family celebrations. Commercialization has significantly influenced the pattern of celebration in the postwar period and as a result, consumption practices have become inherent parts of the ritual. The paper examines this development from a historical perspective. Furthermore, (...) it discusses the process through which consumption practices contribute to the event’s significance, not diminishing but rather enhancing its importance in the observers’ eyes. Conspicuous consumption thus becomes a creative two-directional process, one which is sustained by families’ aspirations and desires, and one which is informed by forces emanating from the commercial sector and from the media.

Focusing on the speculative methodologies used to generate models of the financial and meteorological future, this article develops a series of theses on the ‘evental’ and ‘atmospheric’ quality of contemporary power. What is at stake in the circulation of capital today, I argue, is not so much the exchange of equivalents as the universal transmutability of fluctutation. Whether we are dealing with the turbulence of world financial markets or that of complex earth systems, the non-dialectical relation can itself be extracted, (...) recombined and liquefied, as it were, in a dimension of its own. In the same way that financial derivatives price the variable relation between and across national currencies, weather derivatives now make it possible to issue contracts on the unknowable contingencies embedded in complex atmospheric relations. This reconfiguration of value requires a thorough rethinking of classical sociological conceptions of debt, promise and political violence. (shrink)

Bruno Latour’s long term project is to compare the felicity and infelicity conditions of the different values dearest to the heart of those who have ‘never been modern’. According to him, this is the only way to develop an anthropology of the Moderns. After his work on science, on technology and, more recently, on law, this book explores the truth conditions of religious speech acts.Even though there is no question that religion is one of the values that has been (...) intensely cherished in the course of history, it’s also clear that it has become immensely difficult to tune in to its highly specific mode of enunciation. Every effort to speak in the right key sounds awkward, reactionary, pious or simply empty. Hence the necessity of devising a way of writing that brings to the fore this elusive form of speech to render it audible again. In this highly original book, the author offers a completely different tack on the endless ‘science and religion’ conflict by protecting them both from the confusion with the notion of information. Like The Making of Law, this book is one more attempt at developing this ‘inquiry on modes of existence’ that provides an alternative definition of society. (Publisher's abstract). (shrink)

Child Versus Childmaker investigates a "person-affecting" approach to ethical choice. A form of consequentialism, this approach is intended to capture the idea that agents ought both do the most good that they can and respect each person as distinct from each other. Focusing on cases in which a conflict of interest arises between "childmakers"—parents, infertility specialists, embryologists, and others engaged in the task of bringing new people into existence—and the children they aim to create, the author considers what we today (...) owe those who will come into existence tomorrow.

The identification and valorization of unacknowledged, feminized forms of economic productivity has been an important task for feminist theory. In this article, we expand and rethink existing definitions of labour, in order to recognize the essential economic role women play in the stem cell and regenerative medicine industries, new fields of biomedical research that are rapidly expanding throughout the world. Women constitute the primary tissue donors in the new stem cell industries, which require high volumes of human embryos, oöcytes, foetal (...) tissue and umbilical cord blood. Such material is generally given for free in the advanced industrial democracies, constituted as a surplus (‘spare’ embryos) or waste (umbilical cord ‘afterbirth’, cadaveric foetuses, poor quality oöcytes) whose generative powers should not be withheld from others. At the same time, among impoverished female populations in developing nations, such biological material is now often procured through frankly transactional relations, where women undertake risky procedures for small fees. In each case, female bodily productivity is mobilized to support bioeconomic research, yet the economic value involved in these relations is largely unacknowledged. In this article, we consider both the gift economy and the transactional economy for reproductive tissues as a form of labour. In order to fully conceptualize the specificities of feminized productivity in the bioeconomy, we distinguish between earlier feminist theories of reproductive labour and the emerging practices generated by stem cell research, which we term regenerative labour. We consider how historical transformations in the regulation of feminized labour and the technical repertoires of stem cell research renegotiate the productivity limits of female reproductive biology, opening it out to novel and profitable forms of surplus value and enrolling women in complex negotiations over their role in bioeconomic activity.

What things count as individuals, and how do we individuate them? It is a classic philosophical question often tackled from the perspective of analytic metaphysics. This volume proposes that there is another channel by which to approach individuation -- from that of scientific practices. From this perspective, the question then becomes: How do scientists individuate things and, therefore, count them as individuals? This volume collects the work of philosophers of science to engage with this central philosophical conundrum from a new (...) angle, highlighting the crucial topic of experimental individuation and building upon recent, pioneering work in the philosophy of science. An introductory chapter foregrounds the problem of individuation, arguing it should be considered prior to the topic of individuality. The following chapters address individuation and individuality from a variety of perspectives, with prominent themes being the importance of experimentation, individuation as a process, and pluralism in individuation's criteria. Contributions examine individuation in a wide range of sciences, including stem cell biology, particle physics, and community ecology. Other chapters examine the metaphysics of individuation, its bearing on realism/antirealism debates, and interrogate epistemic aspects of individuation in scientific practice. In exploring individuation from the philosophy of biology, physics, and other scientific subjects, this volume ultimately argues for the possibility of several criteria of individuation, upending the tenets of traditional metaphysics. It provides insights for philosophers of science, but also for scientists interested in the conceptual foundations of their work. (shrink)

Examining stem cell biology from a philosophy of science perspective, this book clarifies the field's central concept, the stem cell, as well as its aims, methods, models, explanations and evidential challenges. The first chapters discuss what stem cells are, how experiments identify them, and why these two issues cannot be completely separated. The basic concepts, methods and structure of the field are set out, as well as key limitations and challenges. The second part of the book shows how rigorous explanations (...) emerge from stem cell experiments, and compares these to other kinds of scientific explanation. Model organisms, the role of genes, and the significance of collaboration are also discussed. The last part of the book considers relations to systems biology and clinical medicine, arguing that both the mathematical models of the former, and ethical principles of the latter, are necessary for stem cell biology to deliver on its promises.

Including empirical examples and theoretical clarifications on many of the analytical issues raised in his recently published Down to Earth, this conversation with Bruno Latour and his collaborator, Danish sociologist Nikolaj Schultz, offers key insights into Latour’s recent and ongoing work. Revolving around questions on political ecology and social theory in our ‘New Climatic Regime’, Latour argues that in order to have politics you need a land and you need a people. This interview present reflections on such (...) politics, such land and such people, and it ends with a call for a sociology that takes up the task of connecting the three by investigating what he and Schultz call ‘geo-social classes’. The interview was conducted by Jakob Stein in Paris in November 2018. (shrink)

Comment combler le fossé apparemment infranchissable séparant la science (chargée de comprendre la nature) et la politique (chargée de régler la vie sociale), séparation dont les conséquences - affaires du sang, de l'amiante, de la vache folle... - deviennent de plus en plus catastrophiques? L'écologie politique a prétendu apporter une réponse à ce défi. Mais après de fracassants débuts, elle peine à renouveler la vie publique... Dans ce livre qui fait suite à Nous n'avons jamais été modernes (La Découverte, 1991), (...) Bruno Latour propose une nouvelle façon de considérer l'écologie politique. La nature a toujours constitué l'une des deux moitiés de la vie publique, celle qui rassemble le monde commun que nous partageons tous, l'autre moitié formant ce qu'on appelle la politique, c'est-à-dire le jeu des intérêts et des passions. D'un côté ce qui nous unit, la nature, de l'autre ce qui nous divise, la politique. Et c'est pourquoi il est faux de prétendre que le souci de la nature caractériserait l'écologie politique : car à cause des controverses scientifiques qu'elle suscite, à cause de l'incertitude sur les valeurs qu'elle provoque, elle oblige à abandonner la nature comme mode d'organisation publique. La question devient donc : comment penser enfin la politique sans la nature? Pour Bruno Latour, la solution repose sur une profonde redéfinition à la fois de l'activité scientifique (à réintégrer dans le jeu normal de la société) et de l'activité politique (comprise comme l'élaboration progressive d'un monde commun). Ce sont les conditions et les contraintes de telles redéfinitions qu'il explore avec une grande rigueur dans cet ouvrage important. A la croisée de la philosophie des sciences et de la philosophie politique, ce livre s'adresse à ceux qui s'intéressent à l'écologie, aux controverses scientifiques, au rôle des experts dans les débats publics, et, plus généralement, à ceux qui estiment que la question de la démocratie doit s'étendre aux sciences elles-mêmes.

The present study investigated whether humans are more likely to trust people who are coordinated with them. We examined a well-known type of linguistic coordination, lexical entrainment, typically involving the elaboration of “conceptual pacts,” or partner-specific agreements on how to conceptualize objects. In two experiments, we manipulated lexical entrainment in a referential communication task and measured the effect of this manipulation on epistemic and practical trust. Our results showed that participants were more likely to trust a coordinated partner than an (...) uncoordinated one, but only when the latter broke previously established conceptual pacts. (shrink)
