Technik bestimmt auf die mannigfaltigste Weise unser Leben und Zusammenleben. Obgleich sie von Platon und Aristoteles bis in das zwanzigste Jahrhundert in Einzelaspekten betrachtet worden ist, wurde sie erst in den letzten Jahrzehnten zu einem eigenständigen Gegenstand der Philosophie. Dennoch werden ihre philosophischen Probleme immer noch eher beiläufig behandelt. So geht es um die Klärung ganz zentraler und herausfordernder Aufgaben – von der menschlichen Schöpferkraft über eine Klärung, was ein technisches Artefakt ist, zum technischen Wissen, in all diesen Elementen verknüpft (...) mit dem Verantwortungsproblem. Das Ziel ist eine Darstellung dieser faszinierenden philosophischen Fragen vor dem Hintergrund der Tradition. (shrink)

English summary: Thinking about God is theology's main task and the philosophy of religion's most noble. Like almost no other theologian and philosopher of religion, Ingolf U. Dalferth's devotion to it has made the paradigms of current philosophical and theological theory construction fruitful. God, in whom people believe and place their trust, is revealed as the First and the Last, as the beginning without end, and the end that renews everything. This Festschrift's twenty-four studies pick up from Dalferth's work by (...) thinking about God in their own way. The richness of the questions they pose, the plurality of the answers, and the diversity of the religious-philosophical and theological perspectives affirm the worthiness of thinking God. German description: Gott zu denken, ist die zentrale Aufgabe der Theologie und die vornehmste der Religionsphilosophie. Wie kaum ein anderer Theologe und Religionsphilosoph hat sich Ingolf U. Dalferth dieser Aufgabe gewidmet und dafur die aktuellen Paradigmen philosophischer und theologischer Theoriebildung fruchtbar gemacht. Gott, an den Menschen glauben und auf den sie ihre Hoffnung setzen, kommt dem Denken als Erstes und Letztes in den Blick, als Anfang, der noch kein Ende gefunden hat, und als Ende, das alles neu macht.Die vierundzwanzig Studien dieser Festschrift nehmen Dalferths Beitrage auf, indem sie je auf ihre Weise Gott nachdenken. Der Reichtum der von ihnen diskutierten Fragestellungen, die Pluralitat der Antworten und die Vielfalt der religionsphilosophischen und theologischen Perspektiven bekraftigen die Denkwurdigkeit Gottes.

TWO OPPOSING VIEWS ABOUT THE RELATIONSHIP between concepts and the world can be found in the history of philosophy. One view—deriving from Immanuel Kant and endorsed by Karl Popper, among many others—claims that in forming and using concepts we structure the world. Concepts produce or increase order. Hence, the world, insofar as it is knowable by human beings, is necessarily a conceptually structured world. The second, still older view—represented by the Aristotelian tradition and by John Locke, for example—holds that concepts (...) are formed by abstracting from the particularities of the world. By leaving out the accidental or irrelevant features of particular entities, we abstract a concept as a general representative of a kind. (shrink)

SummaryThe philosophical core of a psychological theory of cognitive processes is developped and commented, focussing on the problem of intentionality, this term being taken in the normal and in the phenomenological sense. Actions, perceived processes, their states and results, operations and concepts are seen as related insofar as they all establish relations between elements, are generated by construction and can be objectivated. These acts and/or the objectives that control them, are intentional insofar as their structure is activated. Such activation is (...) characteristic of living systems. Intentionality sensu Brentano/Husserl is limited to acts of presentation, a contemplative conception which lacks the constructivity and the dynamism of our pragmatistic concept of action and thought.

The centerpiece of Jeffrey Bub's book Interpreting the Quantum World is a theorem (Bub and Clifton 1996) which correlates each member of a large class of no-collapse interpretations with some 'privileged observable'. In particular, the Bub-Clifton theorem determines the unique maximal sublattice L(R,e) of propositions such that (a) elements of L(R,e) can be simultaneously determinate in state e, (b) L(R,e) contains the spectral projections of the privileged observable R, and (c) L(R,e) is picked out by R and e alone. In (...) this paper, we explore the issue of maximal determinate sets of observables using the tools provided by the algebraic approach to quantum theory; and we call the resulting algebras of determinate observables, "maximal *beable* subalgebras". The capstone of our exploration is a generalized version of Bub and Clifton's theorem that applies to arbitrary (i.e., both mixed and pure) quantum states, to Hilbert spaces of arbitrary (i.e., both finite and infinite) dimension, and to arbitrary observables (including those with a continuous spectrum). Moreover, in the special case covered by the original Bub-Clifton theorem, our theorem reproduces their result under strictly weaker assumptions. This added level of generality permits us to treat several topics that were beyond the reach of the original Bub-Clifton result. In particular: (a) We show explicitly that a (non-dynamical) version of the Bohm theory can be obtained by granting privileged status to the position observable. (b) We show that Clifton's (1995) characterization of the Kochen-Dieks modal interpretation is a corollary of our theorem in the special case when the density operator is taken as the privileged observable. (c) We show that the 'uniqueness' demonstrated by Bub and Clifton is only guaranteed in certain special cases -- viz., when the quantum state is pure, or if the privileged observable is compatible with the density operator. We also use our results to articulate a solid mathematical foundation for certain tenets of the orthodox Copenhagen interpretation of quantum theory. For example, the uncertainty principle asserts that there are strict limits on the precision with which we can know, simultaneously, the position and momentum of a quantum-mechanical particle. However, the Copenhagen interpretation of this fact is not simply that a precision momentum measurement necessarily and uncontrollably disturbs the value of position, and vice-versa; but that position and momentum can never in reality be thought of as simultaneously determinate. We provide warrant for this stronger 'indeterminacy principle' by showing that there is no quantum state that assigns a sharp value to both position and momentum; and, a fortiori, that it is mathematically impossible to construct a beable algebra that contains both the position observable and the momentum observable. We also prove a generalized version of the Bub-Clifton theorem that applies to "singular" states (i.e., states that arise from non-countably-additive probability measures, such as Dirac delta functions). This result allows us to provide a mathematically rigorous reconstruction of Bohr's response to the original EPR argument -- which makes use of a singular state. In particular, we show that if the position of the first particle is privileged (e.g., as Bohr would do in a position measuring context), the position of the second particle acquires a definite value by virtue of lying in the corresponding maximal beable subalgebra. But then (by the indeterminacy principle) the momentum of the second particle is not a beable; and EPR's argument for the simultaneous reality of both position and momentum is undercut. (shrink)

In this accessible collection of short meditations on various topics, Blumenberg works as a detective of ideas scouring the periphery of intellectual and philosophical history for clues—metaphors, gestures, anecdotes—essential to grasping human finitude.

This is a proposal for the re-activation of the essentially stillborn automatic car project for which the cart was originally obtained, and presents a process through which this activation could be accomplished painlessly. The project would be financed from the lab's operating grant, and would interact strongly with, while being independent of, any Mars rover research initiated by Lynn Quam. Since I seem to be the only one, apart from John McCarthy, with an active interest in this aspect of things, (...) the following is written entirely from my point of view. (shrink)

Review of "The Collected Works of Eugene Paul Wigner", Volume I, III, and VI. Excerpt from the Conclusions: Many of Wigner’s papers on mathematical physics are great classics. Most famous is his work on group representations which is of lasting value for a proper mathematical foundation of quantum theory. The modern development of quantum theory (which is not reflected in Wigner’s work) is in an essential way a representation theory (e.g. representations of kinematical groups, or representations of C*-algebras). This view (...) owes very much to Wigner’s seminal papers on the unitary representations of compact and noncompact groups. Wigner showed much courage in relating the then unresolved questions of the measurement problem to the much deeper problem of consciousness. In view of this very unorthodox proposal it is astonishing that Wigner was very reactionary with respect of the dogmas of orthodox quantum mechanics. In contrast to von Neumann himself, he took the old von-Neumann codification of quantum mechanics as authoritative and not to be questioned. Much of the efforts to interpret the meaning of this codification and to prove no-go theorems, such as the insolubility of the measurement problem or the impossibility of a quantum theory of individual objects, are physically irrelevant since they are based on a codification of quantum mechanics that is valid only for strictly closed systems with finitely many degrees of freedom. However, in nature there are no such systems. Every material system is coupled to the gravitational and to the electromagnetic field – systems which require in a Hamiltonian description infinitely many degrees of freedom. A deeper insight into the conceptual problems of quantum theory is possible only if the modern development of a quantum theory of infinite systems is taken into account. (shrink)

When it comes to understanding the ontology of individual existence-that is the everyday behaviors that we all perform and hardly ever think about-the voice has a particularly complicated status. Together with writing, voice is the medium expressing ideas that, broadly speaking, we have previously formed in our minds. At the same time, voices trigger vague images and associations that do not have determinate forms. They remain in our memory, and we may even "hear" them as if immediately present, but we (...) are unable to detach the propositional contents they articulate from the centrifugal effects that they have on our lives. Writing in both a personal and philosophical register, Hans Ulrich Gumbrecht explores the complexity of the voice as an understudied philosophical, social, and existential phenomenon. He starts out with a focus on its core intellectual problem as "the knot of the voice" - referring to the inseparable proximity between meanings, images, and the physical perceptions on which they depend. In conversation with Nietzsche, Husserl, Heidegger, Derrida, Lyotard, Luhmann, and above all Roland Bartes, Gumbrecht addresses topics that range from the social functions of the voice to its status in different historical contexts, and to the ways in which the perception of voices animates imagination. Throughout, incisive analyses of moments such as Julius Caesar's purportedly high-pitched voice, the surprisingly fragile authority of God's voice in the Torah and in the Gospel, and Gumbrecht's own personal attachment to the voices of popular singers such as Edith Piaf, Elvis Presley, and Adele, create a portrait of the voice that is both philosophically challenging and entertaining to read.

In der modernen Medizin kommt es zunehmend zu Entscheidungskonflikten zwischen Intervention und Interventionsverzicht dort, wo nicht die medizinisch-technischen Möglichkeiten handlungsleitend sein sollen, sondern die am individuellen Patientenwohl sich orientierende bioethische Prognose entsprechend den klassischen arztethischen Prinzipien des primum nil nocere und des salus aegroti suprema lex. Schadensverbot und Heilauftrag sollen nicht heteronom und uniform vorgegeben werden, sondern sich am Willen des Patienten orientieren. Nicht selten macht jedoch die Ermittlung des mutmaßlichen Patientenwillens große Schwierigkeiten, vor allem bei Demenz, Koma, schwerem Trauma (...) und Multimorbidität in der Nähe des Todes. Vorsorgliche Betreuungsvollmachten und Behandlungsverfügungen, fälschlich oft 'Patiententestament' genannt, sind als Instrumente für stellvertretende Entscheidungen und zur Ermittlung des Patientenwohles in solchen Situationen vorgeschlagen worden. Der Beitrag analysiert die entscheidungstheoretischen, ethischen, rechtlichen und medizinischen Aspekte prospektiver Entscheidung über eine medizinische Behandlung in einem transkulturellen und interdisziplinären Vergleich von Entscheidungen und Diskussionen in den USA, Japan und der Bundesrepublik Deutschland. Es werden verschiedene Modelle und Betreuungsverfügungen mit unterschiedlicher rechtlicher und medizinischer Validität und Präzision sowie unterschiedlicher kultureller und individueller Akzeptanz entwickelt und diskutiert.
