We initiate the study of computable presentations of real and complex C*-algebras under the program of effective metric structure theory. With the group situation as a model, we develop corresponding notions of recursive presentations and word problems for C*-algebras, and show some analogous results hold in this setting. Famously, every finitely generated group with a computable presentation is computably categorical, but we provide a counterexample in the case of C*-algebras. On the other hand, we show every finite-dimensional C*-algebra is computably (...) categorical. (shrink)

This article by Johannes B. Lotz, S.J., never before translated into English, describes his contacts with Martin Heidegger. First it describes his arrival, along with Karl Rahner, S.J., to pursue doctoral studies in Freiburg im Breisgau and their first experiences with the famous professor. Lotz continues his narrative by mentioning times he met with Heidegger over the subsequent forty years up to the philosopher’s death. With Gustav Siewerth, Max Müller, Bernhard Welte, and Karl Rahner, Lotz belonged to a group of (...) Catholic thinkers influenced—some more, some less—by Martin Heidegger. In Lotz’s view some of Heidegger’s ideas were already found in Aquinas, and a philosophy of Being needed to go beyond existential analysis into religion, revelation, and cultural criticism. (shrink)

abstract This essay considers the moral status of certain practices that aim to enhance offspring traits. I develop an objection to offspring enhancement that draws on an account of the role morality of parents. I work out an account of parental ethics by reference to premises about child development and to observations about parenting culture in the United States. I argue that excellence in parenthood consists in a dual responsibility both to guide children toward the good life and to accept (...) them as they are. I conclude that prenatal manipulation of healthy and normal characteristics in human offspring fails to balance the dispositional extremes of control and restraint to which many parents today are susceptible. I apply this account of good parenting to the challenging case of height enhancement for short but otherwise healthy children. Finally, I reply to objections, first, about the phenomenology of bearing normative obligations to people who do not yet exist and, second, about the moral logic of criticizing embryo selection in the context of assisted reproduction when we accept child selection in the context of adoption.

In spite of vast global improvements in living standards, health, and well-being, the persistence of absolute poverty and its attendant maladies remains an unsettling fact of life for billions around the world and constitutes the primary cause for the failure of developing states to improve the health of their peoples. While economic development in developing countries is necessary to provide for underlying determinants of health – most prominently, poverty reduction and the building of comprehensive primary health systems – inequalities in (...) power within the international economic order and the spread of neoliberal development policy limit the ability of developing states to develop economically and realize public goods for health. With neoliberal development policies impacting entire societies, the collective right to development, as compared with an individual rights-based approach to development, offers a framework by which to restructure this system to realize social determinants of health. The right to development, working through a vector of rights, can address social determinants of health, obligating states and the international community to support public health systems while reducing inequities in health through poverty-reducing economic growth. At an international level, where the ability of states to develop economically and to realize public goods through public health systems is constrained by international financial institutions, the implementation of the right to development enables a restructuring of international institutions and foreign-aid programs, allowing states to enter development debates with a right to cooperation from other states, not simply a cry for charity.

This paper attempts to respond to a call to find an ontological basis for establishing African legal theory. The African world of my choice is the Igbo world of South-east Nigeria. It is a world I want to examine to see how its material and theoretical structures help articulate a philosophy of law in terms of projecting a consistent understanding of law subjects and the foundations of their rights. The article builds on the contributions of F. U. Okafor and his (...) many African critics. (shrink)

Liberal theory seeks to achieve toleration, civil peace, and mutual respect in pluralistic societies by making public policy without reference to arguments arising from within formative ideals about what gives value to human life. Does it make sense to set aside such conceptions of the good when it comes to controversies about stem cell research and the genetic engineering of people or animals? Whether it is reasonable to bracket our worldviews in such cases depends on how we answer the moral (...) questions that the use of these biotechnologies presuppose. I argue that the moral language of liberal justice – of rights and duties, interests and opportunities, freedom and consent, equality and fairness – cannot speak to these underlying concerns about what the human embryo is, why the natural lottery matters to us, and whether 'animal nature' is worth preserving. I conclude that liberal theory is incapable of furnishing a coherent or desirable account to govern the way we use our emerging powers of biotechnology. (shrink)

Vor dem Hintergrund einer weitreichenden Neuorientierung, die der praktischen Vernunft in der Methodologie , in der Sprachphilosophie und in der strukturalen Wissenschaftstheorie den Primat einräumt, werden die Aporien rationalistischdezisionistischer Konzeptionen deutlicher sichtbar. In diesem Papier wird der argumentative Ursprung von Feyerabends Kritik an Rationalität und Wissenschaft als auf einer - angesichts der 'praktischen Wende' der neueren Wissenschaftsphilosophie - überholten Wissenschaftsauffassung basierend analysiert. Feyerabends Zurückweisung der Wissenschaft erscheint dann weder als Konsequenz seiner Vernunftkritik noch als Bruch in seiner Argumentation; er vollstreckt (...) vielmehr die Gegenstandsverfehlung der methodologistischen Wissenschaftstheorie unverdeckt.

Miklos Vetö has already contributed several articles and a textual analysis to Schelling studies. For the University of Turin’s series Philosophica varia he edited a second text of the Romantic Idealist’s Conferences at Stuttgart. That volume was begun by an introduction of a hundred pages containing a masterful presentation of Schelling’s thought at that crucial moment. With Le fondement Vetö, professor at Abidjan, Ivory Coast, gives us a full exposition of Schelling’s many faceted thought. This exposition is arranged around the (...) ultimate source and goal of his thought. In the early systems Schelling called it "consciousness of self" or "the absolute," but Vetö employs as the leitmotif for his book, Grund. This volume is not a precise analysis of the primal and turbulent ground of reality in one or another period of Schelling’s enterprise; it is, rather, a study of richness of Schelling’s thought arranged around the explanation of this term, both from within the various systems of Schelling and from without through his philosophical contemporaries.

The fourth volume in Luigi Pareyson’s collection of Philosophica varia inedita vel rariora published in Turin. All four have dealt with Schelling. Two presented unpublished texts edited by M. Vetö and Horst Fuhrmans. This volume and its companion, Schelling im Spiegel seiner Zeitgenossen, are large collections of hitherto unpublished documents pertaining to the life and work of the idealist philosopher.
