With the advent of synthetic biology, scientists are increasingly relying on digital sequence information, instead of physical genetic resources. This article examines the potential impact of this shift on the access and benefit-sharing (ABS) regime of the Convention on Biological Diversity (CBD) and the Nagoya Protocol. These treaties require benefit-sharing with the owners of genetic resources. However, whether “genetic resources” include digital sequence information is unsettled. The CBD conceives genetic resources as genetic material containing functional units of heredity. “Material” implies (...) tangibility, and for some scholars, “functional units of heredity,” undefined in both treaties, mean full-coding sequences. This article argues that digital sequence information obtained from physical genetic resources, full-coding or not, should be treated as genetic resources. Literal construction of the CBD risks eroding its usefulness and the ABS regime. This is because through bioinformatics, sequence information can easily be obtained from genetic resources for utilization, without physically moving them or concluding ABS agreement with owners. The CBD must evolve with scientific progress also because sequence functionality depends on the state of knowledge. These arguments are vindicated by domestic ABS laws equating genetic information with genetic resources; Nagoya Protocol provisions deeming research exploiting the genetic composition of genetic resources as utilization of genetic resources; and CBD provisions requiring the sharing of benefits from the utilization of genetic resources. Moreover, treaty interpretation and case law demand that generic, scientific terms, such as “genetic resources” and “functional units of heredity” be interpreted in an evolutionary manner to capture scientific developments.

This chapter examines the three projects that constitute contemporary African epistemology and suggests various ways in which they can be put on a firmer footing, and by so doing advance the epistemic goal of the discipline. These three projects include ethno-epistemology, analytic African epistemology and what one might call ameliorative African epistemology. Ethno-epistemology is the study of the phenomenon of knowledge from the perspective of particular African communities as revealed in their cultural heritage, proverbs, folklores, traditions, and practices. Analytic African (...) epistemology involves the philosophical study of concepts such as ‘knowledge,’ ‘justification,’ ‘belief’ and ‘truth’ from the African perspective using the methods of analysis, criticism, arguments, ordinary language philosophy, and so on. And finally, ameliorative African epistemology addresses the predicament of African knowledge systems and voices in the global knowledge and credibility economy within the broader context of the problem of epistemic injustice suffered by historically marginalized groups.

Contemporary health care often lacks generosity of spirit, even when treatment is most efficient. Too many patients are left unhappy with how they are treated, and too many medical professionals feel estranged from the calling that drew them to medicine. Arthur W. Frank tells the stories of ill people, doctors, and nurses who are restoring generosity to medicine--generosity toward others and to themselves. The Renewal of Generosity evokes medicine as the face-to-face encounter that comes before and after diagnostics, pharmaceuticals, (...) and surgeries. Frank calls upon the Roman emperor Marcus Aurelius, philosopher Emmanuel Levinas, and literary critic Mikhail Bakhtin to reflect on stories of ill people, doctors, and nurses who transform demoralized medicine into caring relationships. He presents their stories as a source of consolation for both ill and professional alike and as an impetus to changing medical systems. Frank shows how generosity is being renewed through dialogue that is more than the exchange of information. Dialogue is an ethic and an ideal for people on both sides of the medical encounter who want to offer more to those they meet and who want their own lives enriched in the process. The Renewal of Generosity views illness and medical work with grace and compassion, making an invaluable contribution to expanding our vision of suffering and healing. (shrink)

Die Idee zu der in diesem Band dokumentierten Tagung ist im Rahmen des disziplinübergreifenden Nachwuchswissenschaftsnetzwerkes THESIS entstanden. Der Dialog über die fachlichen und disziplinären Grenzen hinweg hat bei THESIS seit dessen Gründung im Jahre 1990 stets einen großen Raum eingenommen. Anderen Fächern Respekt und Interesse entgegenzubringen und sich nicht von stereotypen Vorurteilen leiten zu lassen, ist konstitutiver Bestandteil im Selbstverständnis des Netzwerkes. Selbstverständlich gibt es in einem solchen Verbund eine Reihe von Gelegenheiten (darunter auch den einen oder anderen entwicklungsfördernden Konflikt), (...) das eigene Bild vom Anderen und das andere Bild vom Eigenen zur Sprache zu bringen und zu hinterfragen. Auf der Basis dieser bestehenden Kommunikationsstrukturen trafen sich am 11. Oktober 2003 in Göttingen 12 junge Wissenschaftlerinnen und Wissenschaftler zwischen, über und auch auf den Grenzen ihrer eigenen Herkunftsdisziplinen, um den Trendbegriff [alpha]Transdisziplinarität" auf seine Substanz zu prüfen.

In At the Will of the Body , Arthur Frank told the story of his own illnesses, heart attack and cancer. That book ended by describing the existence of a "remission society," whose members all live with some form of illness or disability. The Wounded Storyteller is their collective portrait. Ill people are more than victims of disease or patients of medicine they are wounded storytellers. People tell stories to make sense of their suffering when they turn their diseases (...) into stories, they find healing. Drawing on the work of authors such as Oliver Sacks, Anatole Broyard, Norman Cousins, and Audre Lorde, as well as from people he met during the years he spent among different illness groups, Frank recounts a stirring collection of illness stories, ranging from the well-known--Gilda Radner's battle with ovarian cancer--to the private testimonials of people with cancer, chronic fatigue syndrome, and disabilties. Their stories are more than accounts of personal suffering: they abound with moral choices and point to a social ethic. Frank identifies three basic narratives of illness in restitution, chaos, and quest. Restitution narratives anticipate getting well again and give prominence to the technology of cure. In chaos narratives, illness seems to stretch on forever, with no respite or redeeming insights. Quest narratives are about finding that insight as illness is transformed into a means for the ill person to become someone new. (shrink)

This article makes a case for wide reflective equilibrium in doing African epistemology. It argues that on the issue of formulating a viable theory of knowledge, such an approach is more promising than the extant dominant approaches, namely the method of ethno-epistemology and the method of particularistic studies. More specifically, wide reflective equilibrium articulates a proper balance between philosophy and culture and endows a theory of knowledge with multiple sources of normativity.

This paper argues for two interrelated claims. The first is that the most innovative contribution of Timothy Williamson, Herman Cappelen, and Max Deutsch in the debate about the epistemology of thought experiments is not the denial of intuition and the claim of the irrelevance of experimental philosophy but the claim of epistemological continuity and the rejection of philosophical exceptionalism. The second is that a better way of implementing the claim of epistemological continuity is not Deutsch and Cappelen’s argument view or (...) Williamson’s folk psychological view. This is so because while the argument view makes the basis of the relevant classificational judgement evidentially too demanding; the folk psychological view makes it too weak and error-prone to count as an adequate explanation. Drawing from a certain reading of Aristotle’s Nichomachean Ethics that flowers in Miranda Fricker and John McDowell, I argue for the reason-responsiveness view. Like the extant views, the reason-responsiveness view vindicates the claim of epistemological continuity. But unlike the extant views, it does not share those problematic features. Further, I show that the reason-responsiveness view offers a way for champions of the claim of epistemological continuity to resist Avner Baz’s objection to the claim of epistemological continuity and his objection to the philosophical use of thought experiments while taking on board some attractive elements of his view.

A complete collection of Frank Sibley's articles on philosophical aesthetics, this volume includes five, remarkable, hitherto unpublished papers written in Sibley's later years. It addresses many topics, among them the nature of aesthetic qualities versus non-aesthetic qualities, the relation of aesthetic description to aesthetic evaluation, the different levels of evaluation, and the objectivity of aesthetic judgement. The later papers constitute both a significant development of Sibley's individual approach to aesthetics, such as his discussion of the distinction between attributive and (...) predicative uses of adjectives and of the aesthetic significance of tastes and smells, a topic Sibley considered to be much neglected.

Avner Baz argues that the philosophical method of cases presupposes a problematic view of language and linguistic competence, namely what he calls "the atomistic-compositional view". Combining key elements of social pragmatism and contextualism, Baz presents a view of language and linguistic competence, which he takes to be more sensitive to the open-endedness of human language. On this view, there are conditions for the "normal" and "felicitous" use of human words, conditions that Baz thinks are lacking in the context of the (...) philosophical method of cases, and which make the question that philosophers are prone to ask in that context and the answers they give to that question to be pointless. However, in this paper, I argue as follows. First, Baz's conditions for the "normal" and "felicitous" use of human words are in tension with the open-endedness of human language and the use of human words. Second, it is not even clear that those conditions are really missing in the context of the philosophical method of cases. And third, even if we grant that those conditions are missing in that context, this does not licence his damning conclusion on the philosophical method of cases since we are not forced to embrace the view of language and linguistic competence on which that damning conclusion is plausible. This last move is secured by advancing and defending a skill or virtue-based view of language and linguistic competence inspired by the later work of Donald Davidson. (shrink)

This article rebuts Ramsey's earlier theory, in 'Universals of Law and of Fact', of how laws of nature differ from other true generalisations. It argues that our laws are rules we use in judging 'if I meet an F I shall regard it as a G'. This temporal asymmetry is derived from that of cause and effect and used to distinguish what's past as what we can know about without knowing our present intentions.

This book takes up the central themes of Aristotle's metaphysical theory and the various transformations they undergo prior to their full expression in the Metaphysics. Aristotle's metaphysics is bedevilled by classic puzzles involving such notions as form, predication, universal, and substance, which result from his attempt to adapt the various requirements on primary substance developed in his earlier works so that they fit the very different metaphysical picture in his later work. Professor Lewis argues that Aristotle is himself aware of (...) most if not all of these difficulties and in the Metaphysics works hard to ensure the coherence of his theory. He presents Aristotle's views as a formal theory complete with axioms, definitions, and theorems. (shrink)

Recent years have witnessed intensive efforts to specify which requirements ethical artificial intelligence (AI) must meet. General guidelines for ethical AI consider a varying number of principles important. A frequent novel element in these guidelines, that we have bundled together under the term explicability, aims to reduce the black-box character of machine learning algorithms. The centrality of this element invites reflection on the conceptual relation between explicability and the four bioethical principles. This is important because the application of general ethical (...) frameworks to clinical decision-making entails conceptual questions: Is explicability a free-standing principle? Is it already covered by the well-established four bioethical principles? Or is it an independent value that needs to be recognized as such in medical practice? We discuss these questions in a conceptual-ethical analysis, which builds upon the findings of an empirical document analysis. On the example of the medical specialty of radiology, we analyze the position of radiological associations on the ethical use of medical AI. We address three questions: Are there references to explicability or a similar concept? What are the reasons for such inclusion? Which ethical concepts are referred to? (shrink)

Thought experiments play a prominent role in philosophical inquiry. And yet we lack a good understanding of how they work and how they are supposed to supply evidence or knowledge in inquiry. This dissertation offers a novel account of the epistemology of philosophical thought experiments, namely, the reason-responsiveness view. The view is inspired by a virtue ethical tradition that flowers in John McDowell (1994) and Miranda Fricker (2007). Drawing on this virtue ethical tradition, I argue that knowing in philosophical thought (...) experiments is achieved through the exercise of the virtue of sensibility, which has three distinct features. First, it is social in origin, acquired through our training in a human language and as ordinary members of a community. Second, it is recognitional in the sense that although our sensibility gives us the ability to classify situations, whether real or hypothetical and to resonate with rational considerations for or against a given classificational judgement (i.e., the judgements we form in thought experiments), it does not equip us with a reflective ability to fully articulate those reasons in an infallible way. And third, it allows us to project across various contexts, both in real and in hypothetical situations. And this ability to project, I argue further, does not come from the ability of people to grasp concepts or to have certain mental episodes or phenomenology or to grasp universals or to have mastery of the application conditions of rules or from belonging to some exclusive club or from enjoying a certain superior access to concepts or access to philosophically interesting phenomena not available to ordinary people. On the contrary, that we do comes down to “our sharing routes of interest and feeling, mode of response, senses of humour and of significance, of what is outrageous, of what is similar to what else, what a rebuke, what forgiveness, of when an utterance is an assertion, when an appeal, when an explanation—all the while of organism Wittgenstein calls “forms of life” (Cavell, 1969, p.52). The account is then used to shore up the claim of epistemological continuity, which asserts that the epistemology of thought experiments is an extension of social cognition or social epistemology (Cappelen, 2012; Deutsch, 2015; Williamson 2007), and to offer a claim of epistemological-continuity-style defence of philosophical thought experiments against two major objections in the literature, namely, the negative experimentalist challenge (see Machery, 2017) and the ordinary language challenge ( Baz, 2016, 2017).

According to an influential characterisation of reflective equilibrium, it is a kind of algorithm for licensing explicitly normative claims in philosophical inquiries. Call this the machine-view of reflective equilibrium. The machine-view implies a causal relation between input and output data that is devoid of human agency in any significant sense. In this paper, I argue for a neo-Aristotelian alternative view. According to this view, the judgement that is called forth in the decision procedure of reflective equilibrium is a rational response (...) of an epistemic agent, which integrates the whole of her character as a knower, both cognitive and affective, and which cannot be reduced to the explicit following of rules or an algorithm. Unlike the machine-view, this alternative account is able to support the dynamic structure and the normative status of the decision procedure. (shrink)

The Metaphysical Club, a gathering of intellectuals in the 1870s associated with Harvard, is widely recognized as the crucible where pragmatism, America's distinctively original philosophy, was refined and proclaimed. Louis Menand's bestseller about the group was a dramatic publishing success. However, only three actual members - Oliver Wendell Holmes Jr., Charles S. Peirce, and William James - appear in this book, alongside other thinkers such as John Dewey who were never in the Club. The Real Metaphysical Club tells the full (...) story of how this influential group shifted the course of philosophy in America. In addition to pioneering pragmatism, the group explored radical empiricism and idealism, and formulated personalism and process philosophy, equally important developments. This volume contains thirty-seven important writings dating from 1870 to 1885 by the real members of the Metaphysical Club. The first section centers on pragmatism and science; the second part collects writings of the lawyers; and the third part covers idealist and personalist philosophers. Many of these writings have never been reprinted before, and nothing like this impressive collection has ever been attempted. A general introduction provides a narrative history, and the editors' three introductions to the volume's sections vividly bring to life the intense meetings, sustained debates, and pioneering thought from the Metaphysical Club.

English summary: »Selbstbestimmung« is a basic concept in the German ethical discourse, similar to »autonomy«, »liberty«, or »human dignity«. Even though this term is clearly in need of further definition, it has been barely addressed in the theological discourse. The contributions to this volume take a variety of approaches to the question of how we have to understand and interpret the concept of »self-determination« within the framework of theological ethics. In order to achieve this, the authors resort to the orientation (...) and perspectives of reality fostered by reformatory theology. Apart from a fundamental essay that in tracing the different facets of the term »self-determination« refers back to the theology of Martin Luther, the anthology contains a number of contributions from the field of applied ethics. German description: Der Begriff »Selbstbestimmung« gehort zu den Grundbegriffen der Ethik. Er begegnet in vielen aktuellen ethischen Diskursen Ahnlich haufig wie die Begriffe »Autonomie«, »Freiheit« oder »Menschenwuerde«. Trotz eines offensichtlichen Klarungsbedarfs hat sich die Theologie dieses Begriffs bisher noch kaum angenommen. Die Beitrage des vorliegenden Sammelbandes stellen sich in unterschiedlicher Perspektive der Frage, wie das Konzept »Selbstbestimmung« im Rahmen theologischer Ethik verstanden und inhaltlich gefuellt werden kann. Dafuer wird die Orientierungsleistung des von der reformatorischen Theologie gepragten Wirklichkeitsverstandnisses fruchtbar gemacht. Neben einem grundlegenden Aufsatz, der den Begriff »Selbstbestimmung« mit Hilfe von Impulsen aus der Theologie Martin Luthers entfaltet, stehen Aufsatze aus dem Bereich der angewandten Ethik.

Frank Ramsey was the greatest of the remarkable generation of Cambridge philosophers and logicians which included G. E. Moore, Bertrand Russell, Ludwig Wittgenstein and Maynard Keynes. Before his tragically early death in 1930 at the age of twenty-six, he had done seminal work in mathematics and economics as well as in logic and philosophy. This volume, with a new and extensive introduction by D. H. Mellor, contains all Ramsey's previously published writings on philosophy and the foundations of mathematics. The (...) latter gives the definitive form and defence of the reduction of mathematics to logic undertaken in Russell and Whitehead's Principia Mathematica; the former includes the most profound and original studies of universals, truth, meaning, probability, knowledge, law and causation, all of which are still constantly referred to, and still essential reading for all serious students of these subjects.

Recent philosophical discussion about the relation between fiction and reality pays little attention to our moral involvement with literature. Frank Palmer's purpose is to investigate how our appreciation of literary works calls upon and develops our capacity for moral understanding. He explores a wide range of philosophical questions about the relation of art to morality, and challenges theories that he regards as incompatible with a humane view of literary art. Palmer considers, in particular, the extent to which the values (...) and moral concepts involved in our understanding of human beings can be said to enter into our understanding of, and response to, fictional characters. The scope of his discussion encompasses literary aesthetics, ethics, and epistemology, and he makes extensive reference to literary examples. (shrink)

Space, Time, and Stuff is an attempt to show that physics is geometry: that the fundamental structure of the physical world is purely geometrical structure. Along the way, he examines some non-standard views about the structure of spacetime and its inhabitants, including the idea that space and time are pointless, the idea that quantum mechanics is a completely local theory, the idea that antiparticles are just particles travelling back in time, and the idea that time has no structure whatsoever. The (...) main thrust of the book, however, is that there are good reasons to believe that spaces other than spacetime exist, and that it is the existence of these additional spaces that allows one to reduce all of physics to geometry. Philosophy, and metaphysics in particular, plays an important role here: the assumption that the fundamental laws of physics are simple in terms of the fundamental physical properties and relations is pivotal."--P.

I argue that it may well be the case that space and time do not consist of points, indeed that they have no smallest parts. I examine two different approaches to such pointless spaces : a topological approach and a measure theoretic approach. I argue in favor of the measure theoretic approach.

An introduction to informal logic, critical thinking and rhetoric utilizing actual public discourse .

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Happiness in Premodern Judaism: Virtue, Knowledge, and Well-BeingDaniel H. FrankHava Tirosh-Samuelson. Happiness in Premodern Judaism: Virtue, Knowledge, and Well-Being. Cincinnati: Hebrew Union College Press, 2003. Pp. xi + 596. Cloth, $50.00.Franz Rosenzweig tried hard to convince the neoKantian Hermann Cohen of the merits of Zionism and the normalization it would bring to Jews and Jewish life. His attempt met with this response from Cohen: "Oho! So the gang (...) now wants to be happy, does it?" For those ignorant of the history of Jewish philosophy, one might imagine that Jewish philosophers, no less than their non-philosophical kinsmen, were so weighed down by the burdens of history and persecution that happiness could play no role in their theorizing. But happiness plays a key role in the history of Jewish moral and political philosophy, especially in the premodern period. Even Spinoza, the last of the medievals and the first of the moderns, the great critic of the rabbinic tradition and of Maimonides in particular, is concerned in his Ethics with identifying those activities that together constitute human well-being and the good life. Only lately, since the Enlightenment and Kant, has non-eudaimonism been a live option for Jewish thinkers. Only with the rise of (modern) Orthodoxy, and its predilection for construing goodness as rectitude and rule-following, has eudaimonism fallen out of favor. But with Tirosh-Samuelson's weighty volume on happiness in premodern Judaism, there can be no excuse in the future to imagine that all Jews are, or must be, closet Kantians, strict deontologists. To think otherwise seems to come close to taking on the classical (anti-Semitic) dichotomy of legalistic Judaism vs. spiritual Christianity. In it own way, Happiness in Premodern Judaism is a critique of such a one-sided, monochromatic view of Judaism, whether from the Christian or even from the Jewish side.Tirosh-Samuelson writes explicitly as an intellectual historian, rather than as a philosopher. She understands herself and her project as one that presents just the facts, without evaluating them. While one may cavil at a lost opportunity, in the present case this would be churlish, given the enormous erudition on display. After an introductory chapter outlining the foundational moral theories of Plato, Aristotle, and the Hellenistic philosophers, the text presents the (Greek-inspired) areteic wisdom literature of the Second Temple period, the teleological theocentrism of the rabbis, the Greco-Arabic Islamicate culture that nurtured Jewish philosophers from Saadia in the tenth century to Maimonides in the twelfth, the rabbinic and kabbalistic critiques of the philosophical ideal of happiness commencing [End Page 338] with the translation (into Hebrew) of Maimonides' Guide of the Perplexed at the beginning of the thirteenth century, and finally, very important and the focus of much recent scholarly work, the transformation of Jewish eudaimonism through direct contact with Christian Scholasticism and later with the humanist Renaissance. All in all, a millennium and a half of Jewish intellectual history is presented in a sober and scholarly way.Not surprisingly Maimonides plays a pivotal role in the story that Tirosh-Samuelson relates. A Janus-like figure, he represents the culmination and height of accommodation with Greek and Greco-Arabic philosophical culture. However, with the gradual worsening of the socio-economic condition of European Jewry in the thirteenth century, his accommodationism seemed traitorous, and as a result generations of thinkers, mystics and philosophers alike, strove to critically distance themselves from Maimonidean Aristotelianism. Tirosh-Samuelson is admirably clear in pointing out that such anti-Maimonidean tendencies are ill-characterized as anti-philosophical. Hasdai Crescas in the late-fourteenth and early-fifteenth centuries launched a massive critique of Maimonides' physics, metaphysics, and moral philosophy, but did so in as rigorous a manner as any philosopher would. The picture that enfolds over the course of the text is one of vigorous dialectic between partisans of 'alien' (Greek) wisdom and those who viewed such wisdom with considerable suspicion. Such a dialectic parallels, not surprisingly, developments in Christian philosophy.The trajectory of the story of premodern Jewish musings on happiness is from the centrality of reason and intellect, and the contemplative activity that is reason's preeminent actuality, to the primacy...

In this paper, I derive a syntactic procedure for revising theories in propositional logic from considerations of indifference and informational economy (minimality). The procedure is very flexible. It allows us to make use of information about the relative epistemic merit (entrenchment) of the sentences in the theories whenever such information is available, and, unlike other procedures proposed in the literature, yields plausible results even for very simple entrenchment orderings.
