Can we use technology in the pursuit of a good life, or are we doomed to having our lives organized and our priorities set by the demands of machines and systems? How can philosophy help us to make technology a servant rather than a master? Technology and the Good Life? uses a careful collective analysis of Albert Borgmann's controversial and influential ideas as a jumping-off point from which to address questions such as these about the role and significance of technology (...) in our lives. Contributors both sympathetic and critical examine Borgmann's work, especially his "device paradigm" apply his theories to new areas such as film, agriculture, design, and ecological restoration and consider the place of his thought within philosophy and technology studies more generally. Because this collection carefully investigates the issues at the heart of how we can take charge of life with technology, it will be a landmark work not just for philosophers of technology but for students and scholars in the many disciplines concerned with science and technology studies.

In the past thirty years environmental ethics has emerged as one of the most vibrant and exciting areas of applied philosophy. Several journals and hundreds of books testify to its growing importance inside and outside philosophical circles. But with all of this scholarly output, it is arguably the case that environmental ethics is not living up to its promise of providing a philosophical contribution to the resolution of environmental problems. This article surveys the current state of the field and offers (...) an alternative path for the future development of environmental ethics toward a more publicly engaged model of applied philosophy.

Selectional preferences have a long history in both generative and computational linguistics. However, since the publication of Resnik's dissertation in 1993, a new approach has surfaced in the computational linguistics community. This new line of research combines knowledge represented in a pre‐defined semantic class hierarchy with statistical tools including information theory, statistical modeling, and Bayesian inference. These tools are used to learn selectional preferences from examples in a corpus. Instead of simple sets of semantic classes, selectional preferences are viewed as (...) probability distributions over various entities. We survey research that extends Resnik's initial work, discuss the strengths and weaknesses of each approach, and show how they together form a cohesive line of research. (shrink)

J. Baird Callicott has thrown down the gauntlet once again in the monism?pluralism debate in environmental ethics. In a recent article he argues that his ?communitarianism? (combined with a limited intertheoretic pluralism) is sufficient to get the advantages of pluralism advocated by his critics, while at the same time retaining the framework of moral monism. Callicott's attempt to set the record straight on the monism?pluralism debate has once again derailed us from answering the most important question in this discussion: how (...) do we achieve a compatibilism among ethical theories which will inform better environmental practices? But if Callicott got it wrong, then who is getting it right? Arne Naess, whose work has heretofore been excluded from the mainstream discussion of this issue, has all along understood the heart of the monism?pluralism question. This paper updates the current state of the monism?pluralism debate, provides an answer to Callicott's latest challenge, and advances the thesis that all involved in this argument would do well to take a look at what Naess has to say on this issue.

Philosophers and geographers have converged on the topic of public space, fascinated and in many ways alarmed by fundamental changes in the way post-industrial societies produce space for public use, and in the way citizens of these same societies perceive and constitute themselves as a public. This volume advances this inquiry, making extensive use of political and social theory, while drawing intimate connections between political principles, social processes, and the commonplaces of our everyday environments.

The question has become a perennial one in environmental ethics, as well as in allied fields in environmental history, sociology, and politics. And just when we think it is settled—as many did after William Cronon's famous deconstruction of wilderness in (...) 1995—and it feels safe to go back into the metaphysical waters of environmental philosophy, such issues pop up again to send us running.What follows extends this debate in the context of Eric Katz's well-known work in environmental ethics. Brought together here are Katz and two critics sympathetic to his positions, Wayne Ouderkirk and Ned Hettinger. While the occasion for the exchange was the publication of Katz's book, Nature as Subject: Human Obligation and Natural Community (1997), which collects his papers from 1979 to 1996, the focus quickly became somewhat narrower, centering on possible problems with Katz's ontological dualism between natural and artifactual entities.Katz has exerted a strong influence on the development of environmental ethics, particularly through his persistent arguments for a distinction between individualist and holist approaches to obligations to the nonhuman natural world and his metaphysical and moral critique of attempts [End Page 102] by humans to create, repair, or restore nature. While these positions continue to be on display here, there is also something more. In this exchange Katz throws down the gauntlet on his nature-culture dualism, admitting at the start that the accusation is true. Like the Protestants in Monty Python's The Meaning of Life, he is a dualist—and fiercely proud of it! Despite whatever misgivings I or others may have about this position, I believe that in making this claim, Katz, similar to David Chalmers's open embrace and resuscitation of dualism in philosophy of mind, has done us a great service. For it is arguably true that many environmental philosophers, along with other academics, have settled into a complacent "labeling as argument" pattern. If we can label a position as "dualist" or "essentialist," then our work is done. But surely not every form of dualism is necessarily wrong, even if, as Ouderkirk reminds us in his reading of Val Plumwood's work, the logic of many forms of dualism has tended toward a pernicious pattern. Arguments are needed in both directions. If nature-culture dualism is mistaken or wrongheaded, or leads to unfortunate conclusions, then we must know why; if dualism is the only way to make sense of the hurdles presented to us in coming to a better understanding of the value of nature and culture then we must know why as well. And further, because many in the field have assumed a nature-culture dualism without admitting to it, we can admire that Katz chooses to "fess up" and finally put the issue squarely on the table.If this is the road we are heading down with this particular exchange, then we are off to a good start. Both critics of Katz do a thorough job of pressing home their arguments, rather than only pointing accusatory fingers. Ned Hettinger, in "The Problem of Finding a Positive Role for Humans in the Natural World," avoids using the term "dualism," but nonetheless argues that Katz has a tendency to "rigidly dichotomize the natural/artifactual distinction." Additionally, Hettinger argues that Katz tends to overlook his own admission that the differences between nature and artifacts admit to degrees rather than a strict dualism. Hettinger focuses the bulk of his critique on the unfortunate upshot of such a position: given such a distinction, there is little if any place for a positive role for human intervention in nature, or for a philosophical contribution to the formation of better environmental policies.Wayne Ouderkirk, in "Katz's Problematic Dualism and its 'Seismic' Effects on His Theory," is sympathetic with Katz's intuitions that some distinction is needed between artifacts and natural entities.

Environmental pragmatism is a new strategy in environmental thought. It argues that theoretical debates are hindering the ability of the environmental movement to forge agreement on basic policy imperatives. This new direction in environmental thought moves beyond theory, advocating a serious inquiry into the merits of moral pluralism. Environmental pragmatism, as a coherent philosophical position, connects the methodology of classical American pragmatic thought to the explanation, solution and discussion of real issues. This concise, well-focused collection is the first comprehensive presentation (...) of environmental pragmatism as a new philosophical approach to environmental thought and policy. (shrink)

How do we ready ourselves to intervene responsively in the contingent situations that arise in co-designing to make change? How do we attune to group dynamics and respond ethically to unpredictable developments when working with 'community'? Participatory Design can contribute to social transitions, yet its focus is often tightly tuned to technique for designing ICT at the cost of participatory practice. We challenge PD conventions by addressing what happens as we step into a situation to alter it with others, an (...) aspect of practice that cannot be replicated or interchanged. We do so to argue that practices of readiness are constituted by personal histories, experiences, philosophies and culture. We demonstrate this political argument by giving reflexive accounts of our dimensions of preparation. The narratives here are distinct, yet reveal complementary theories and worldviews that shape PD ontologies. We have organized these around the qualities of punctuation and poise as a way to draw out some less easily articulated aspects of PD practice. (shrink)

Biobanks are increasingly being linked together into global networks in order to maximise their capacity to identify causes of and treatments for disease. While there is great optimism about the potential of these biobank networks to contribute to personalised and data-driven medicine, there are also ethical concerns about, among other things, risks to personal privacy and exploitation of vulnerable populations. Concepts drawn from theories of globalisation can assist with the characterisation of the ethical implications of biobank networking across borders, (...) which can, in turn, inform more ethically sophisticated responses. Using the China Kadoorie Biobank as a case study, we show how distinguishing between the subnational, transnational, supranational and extranational spheres of operation and influence can help researchers, institutions and regulators to understand and manage the ethical issues raised by the globalisation of biobanking.

The convergence of biomedical and information technology holds the potential to alter the discourses of identity, or as is argued here, to turn us inside out. The advent of digital networks makes it possible to ‘see inside’ people in ways not anticipated and thus create new performance arenas for the expression of identity. Drawing on the ideas of Butler and Foucault and theories of performativity, this paper examines a new context for human-computer interaction and articulates potentially disturbing issues with (...) monitoring health rather than wellbeing. It argues that by adopting explicitly social framings we can see beyond the idea of medical interventions for health to recognize the political implications of the new categorizations and their implementation in code. In the process, it critiques traditional ways of understanding machine-body relations within the field of technology design. (shrink)

We live in a world confronted by mounting environmental problems; increasing global deforestation and desertification, loss of species diversity, pollution and global warming. In everyday life people mourn the loss of valued landscapes and urban spaces. Underlying these problems are conflicting priorities and values. Yet dominant approaches to policy-making seem ill-equipped to capture the various ways in which the environment matters to us. Environmental Values introduces readers to these issues by presenting, and then challenging, two dominant approaches to environmental decision-making, (...) one from environmental economics, the other from environmental philosophy. The authors present a sustained case for questioning the underlying ethical theories of both of these traditions. They defend a pluralistic alternative rooted in the rich everyday relations of humans to the environments they inhabit, providing a path for integrating human needs with environmental protection through an understanding of the narrative and history of particular places. The book examines the implications of this approach for policy issues such as biodiversity conservation and sustainability. Written in a clear and accessible style for an interdisciplinary audience, this volume will be ideal for student use in environmental courses in geography, economics, philosophy, politics and sociology.

BackgroundBiobanks provide an important foundation for genomic and personalised medicine. In order to enhance their scientific power and scope, they are increasingly becoming part of national or international networks. Public trust is essential in fostering public engagement, encouraging donation to, and facilitating public funding for biobanks. Globalisation and networking of biobanking may challenge this trust.MethodsWe report the results of an Australian study examining public attitudes to the networking and globalisation of biobanks. The study used quantitative and qualitative methods in conjunction (...) with bioethical analysis in order to determine factors that may contribute to, and threaten, trust.ResultsOur results indicate a generally high level of trust in biobanks and in medical research more broadly. Key factors that can reduce perceived trustworthiness of biobanks are commercialisation and involvement in global networking.ConclusionsWe conclude that robust ethical oversight and governance standards can both promote trust in global biobanking and ensure that this trust is warranted.

In 1672, inspired by the wave theory of Ignace Gaston Pardies, Christiaan Huygens made his first attempt to explain the sine law of refraction, but in 1673 he abandoned his plans owing to difficulties concerning double refraction. Huygens was able to explain double refraction on 6 August 1677 after his discoveries of the axis of symmetry of the crystal and of ‘Huygens's principle’. On 6 August 1679, he wrote: ‘I have found the confirmation of my theory of light and (...) of refraction’, and then described an ‘experimentum crucis’ to decide between his theory and a rival hypothesis. A study of caustics may have led Huygens to the discovery of ‘Huygens's principle’. (shrink)

Euler ’s wave theory of light developed from a mere description of this notion based on an analogy between sound and light to a more and more mathematical elaboration on that notion. He was very successful in predicting the shape of achromatic lenses based on a new dispersion law that we now know is wrong. Most of his mathematical arguments were, however, guesswork without any solid physical reasoning. Guesswork is not always a bad thing in physics if it (...) leads to new experiments or makes the theory coherent with other theories. And Euler tried to find such experiments. He saw the construction of achromatic lenses, the explanation of colors of thin plates and of the opaque bodies as proof of his theory. When it came to the fundamental issues, the correctness of his dispersion law and the prediction of frequencies of light he was not at all successful. His wave theory degenerated, and it was not until Augustin Fresnel introduced transverse waves and an elaborate notion of interference that the wave theory again progressed. (shrink)

It has not been sufficiently emphasized that there existed two kinds of modification theory of colours, Aristotle's modification theory and Descartes-Hook's modification theory. This seems to have caused some confusion in the interpretation of the optical controversy between Newton and Hooke in 1672. The aim of the present paper is to prove that these two kinds of modification theory really coexisted, and on that basis to present a new interpretation of the optical controversy of 1672. The characteristics and the historical (...) role of each of these theories will be described. Newton's colour theory was formed under the influence of Aristotle's modification theory, which had been disseminated through the work of an English Gassendist, Walter Charleton. Newton's optical theories were created not only under the influence of Descartes, as we have been often told, but also under the conspicuous influence of corpuscular philosophers. (shrink)

The somewhat deflating conclusion of Simon A. Gilson's meticulous examination of Dante's incorporation of the science of optics and theories of light is that the poet was considerably less well read than we have been giving him credit for.Gilson's book is divided into two parts: the first, dealing with the science of optics, contains four chapters; the second, dealing with theories of light, contains three. Each of these parts is devoted to debunking a tendency in Dante (...) scholarship to attribute to a particular scientific or philosophical movement a marked influence on his work. In the first part Gilson maintains that Dante's use of the science of optics does not—as others, most forcefully and influentially Alessandro Parronchi, have argued—rely specifically on knowledge of the authors of the perspectivae—detailed treatises on optics that placed the influence of light rays at the origin of terrestrial phenomena—that is, on such thinkers as Alhazen, Roger Bacon, and Robert Grosseteste. Rather, Gilson contends that Dante could easily have come by the requisite expertise concerning this science through contact with the more popular and widely known doctrines of such Arab interpreters of Aristotle as Avicenna and Averroës and the commentaries of Albert the Great and Thomas Aquinas. He demonstrates the plausibility of this contention by way of a comparative analysis of the doctrines of the perspectivists and the Arab interpreters. This analysis is followed by a chapter devoted to optics and vision in Dante's earlier poetry.The two following chapters cover, respectively, topics such as blinding, optical illusions, and visual error in Dante's Commedia and the themes of reflection, mirrors, and meteorological optics, also in the Commedia, a work that Gilson specifies as having nevertheless gone beyond the more limited sources of the earlier poetry. In the third chapter Gilson's analysis achieves a welcome degree of insight into the poet's originality: here Gilson shows how Dante incorporates the scientific knowledge of his day in order to establish a set of limits that circumscribe human action in the physical world but that must be overcome in the course of the pilgrim's journey through his imaginative world. Such moments provide a refreshing alternative to an otherwise rather positivistic view of scientific knowledge as a compendium of facts and sources one either has or has not read. One cannot help but think that researchers in the field of the history of science might be most interested in the imaginative contributions of a specifically poetic knowledge, especially in an age in which the distinction between “hard” and “soft” science was not accorded the kind of unquestioned respect it currently receives.In the second part Gilson, continuing his debunking analysis, argues that the scholarship on Dante and his use of theories of light has remained captivated by the notion of “the metaphysics of light.” This term, Gilson claims, has been used to unify and oversimplify a rather diverse group of doctrines concerning the nature of light and its relation to knowledge, vision, God, and being. Against the grain of the traditional critical trend, Gilson maintains that Dante's thought has nothing in common with the proper metaphysics of light of a Grosseteste—who identifies light as the primary element of being—and that Dante would have had relatively little contact with Neoplatonic theories of emanation. Again, according to Gilson, in applying the imagery of light to his poetic themes, Dante would have had readily available models in the popular theological light imagery of his time; his use of light in the description of the Empyrean is, Gilson states, perhaps the best example of Dante's relative independence from any limited set of sources.Whether Gilson's informative examination of Dante's relative dependence on sources should be understood as liberating the poet from the anxiety of scientific influence remains, however, an open question. Whatever the extent or depth of any enumeration of those sources, it is the moment of creation that astonishes. (shrink)

In this paper, I argue that Hume’s account of moral judgment is best understood if it is read in light of Hume’s explanatory project. I first lay out the textual support to show that Hume’s account of justice in the Treatise includes both approval of a motive that gives rise to the virtue of justice, and approval of a system of conduct, irrespective of a motive. I then argue that we can allow for such plurality in Hume’s theory of (...) moral judgment if we view it in light of his explanatory project: finding unifying causes for disparate phenomena. Hume offers a unified theory of moral judgment because he can show that the different approvals are explained by the same causes. Finally, I argue that viewing Hume’s account of moral judgment in light of his explanatory project allows us to appreciate a further distinction between the moral judgment of the natural and the artificial virtues: while judgments of the former are fully explained by the causes of a certain motive, the latter are only fully explained by the causes of the motive in the context of a convention, which in turn is partially constituted by non-approved motives.

The aim of this paper is to explore how the cosmic soul works and how it accomplishes its providential and demiurgic tasks in Chrysippus’ system. Drawing on (i) the analogy Chrysippus establishes between the individuum and the cosmos and (ii) biological and medical theories of respiration, digestion, and pulse, I will show that the movements of Chrysippus’ cosmic soul reproduce the processes of digestion, pulse, and respiration at a cosmic level. My claim is that Chrysippus, in addition to adopting (...) Praxagoras’ notion that inhaled air nourishes pneuma—well established in the scholarship—appropriated Aristotle’s complex mechanism of respiration and digestion based on the teleological role of cold air, crucial for preserving vital heat. So understood, Chrysippus’ application of biological notions to cosmology allows him to endow the active principle with effective causation throughout the cosmos. (shrink)

Simon Schaffer has published a constructivist analysis of the acceptance of Newton’s theory of color that focuses on Newton’s experiments, the continual controversies over them, and his power and authority. In this article, I show that Schaffer’s account does not agree with the historical evidence. Newton’s theory was accepted much sooner than Schaffer holds, when and in places where Newton had little power; many successfully repeated the experiments and few contested them; and theory mattered more than experiment in acceptance. I (...) also present an alternative account of the acceptance of Newton’s theory that shows that, despite criticism when it was first published in 1672, the theory, or parts of it, gradually came to be accepted by mathematical scientists—including Huygens and Leibniz—and Scottish natural philosophers by the time of the publication of the Opticks in 1704. On the Continent, it was coming to be accepted within a decade or so after its publication, that is, before 1716, when Newton replied to a challenge, purportedly by Leibniz, that Schaffer sees as the crucial conflict that at last gave Newton’s experiments their authority.

The article deals with the problem of the divine light in the mystical works of St Symeon the New Theologian in the context of the Eastern Christian ascetical tradition. The author focuses on the passages referring to the divine light in the works of Evagrios Pontikos, St Isaac the Syrian, St Maximus the Confessor, and in the Makarian corpus. As is shown in the present contribution, none of these authors created a fully-developed theory of the vision of the (...) divine light. Being close to these writers in many ideas, St Symeon was generally independent of any of them in his treatment of the theme of vision of light, always basing himself primarily upon his own experience.

Leonhard Euler was the leading eighteenth-century critic of Isaac Newton's projectile theory of light. Euler's main criticisms of Newton's views are surveyed, and also his alternative account according to which light is a wave motion propagated through the aether. Important changes are identified as having occurred between 1744 and 1746 in Euler's thinking about the way in which a wave such as he supposed light to be is propagated through a medium. Paradoxically, in view of Euler's overtly (...) anti-Newtonian stand, these amount to Euler abandoning his early, Malebranchian notions about the physical basis of wave propagation, in favour of the ideas set out by Newton in Book II of his Principia.
