In zwanzig Beiträgen behandelt der vorliegende Sammelband Karl Jaspers in seiner historischen und aktuellen Bedeutung als Psychiater und Philosoph. Das Panorama der verschiedenen wissenschaftlichen Disziplinen, die dabei zu Wort kommen und aufeinander Bezug nehmen, reicht von Psychiatrie, Medizingeschichte, Allgemeinmedizin, Philosophie und Soziologie über Zeitgeschichte, Literaturwissenschaft und Kulturgeschichte bis zur Filmwissenschaft. Immer geht es um ein ganzheitliches Menschenbild in programmatischer Orientierung an einer Zielgruppe, die auch den Nicht-Spezialisten umfaßt. Der Band gliedert sich übersichtlich in ”Zugänge“, ”Interpretationen“ und ”Beziehungsfelder“.

Georg Ernst Stahl (1659-1734) was a German physician and chemist. The book (in German) documents a symposium of the Academy Leopoldina on his works and thoughts that contributed to the Enlightenment. Der weite Horizont seines Denkens und seiner Arbeiten umfasst die Phlogiston-Theorie der Verbrennung, die später mit der Entdeckung des Sauerstoffs widerlegt wurde, aber dennoch wichtige Erkenntnisse zur Reversibilität von Reaktionen und zur unsichtbaren Persistenz der beteiligten chemischen Komponenten beitrug. Seine Gedanken zur Rolle der „Anima“, die heute überholt erscheinen, führten (...) bereits am Beginn des 18. Jahrhunderts Konzepte ein, die für die moderne Biologie und Psychologie von Bedeutung sind. Dazu zählen etwa Homöostase, Synergie, die Vorbereitung willentlicher Bewegungen und Unterschiede zwischen unbewussten aber vernünftigen Handlungen und solchen, die von rationalen Erwägungen geleitet werden. Stahls medizinisches Hauptwerk ist die „Theoria medica vera”, Halle 1708. Eine der zentralen Publikationen zur chemischen Theorie der Verbrennung ist die „Zymotechnia fundamentalis seu fermentationis theoria generalis”, Halle 1697, in deutscher Sprache 1734.

In the opinion of the natural sciences and medicine of the Romantic Era Paracelsus represents a central step from the Middle Ages to Modern Times. Their interpretations of this perceived kindred spirit not free from criticism focus on metaphysical orientations, holistic approach to cosmology and anthropology, biochemical perspective, ethical dominance, immanent union of etiology, pathophenomenology and therapy.

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of each class of (...) pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

Hegel. La Odisea del Espíritu reúne la totalidad de las conferencias pronunciadas en el congreso homónimo que, coordinado por Félix Duque, se celebró en el Círculo de Bellas Artes y la Universidad Autónoma de Madrid entre el 28 de mayo y el 1 de junio de 2007 con motivo del segundo centenario de la publicación de "La Fenomenología del Espíritu". El congreso reunió a los mayores especialistas en la obra del pensador alemán y el resultado es una aportación de primer (...) orden a los estudios hegelianos, un libro de referencia imprescindible para quien quiera adentrarse en el magma de ideas y sugerencias de su libro capital. Incluye ensayos de Félix Duque, Volker Rühle, Walter Jaeschke, Jorge Pérez de Tudela, José María Ripalda, Eduardo Álvarez, Dietrich Von Engelhardt, Antonio Gómez Ramos, Klaus Vieweg, Ángel Gabilondo, Jacinto Rivera de Rosales, Paolo D'Angelo, Christoph Jamme, Vincenzo Vitiello y Klaus Düsing.

How can different individuals' probability assignments to some events be aggregated into a collective probability assignment? Classic results on this problem assume that the set of relevant events -- the agenda -- is a sigma-algebra and is thus closed under disjunction (union) and conjunction (intersection). We drop this demanding assumption and explore probabilistic opinion pooling on general agendas. One might be interested in the probability of rain and that of an interest-rate increase, but not in the probability of rain or (...) an interest-rate increase. We characterize linear pooling and neutral pooling for general agendas, with classic results as special cases for agendas that are sigma-algebras. As an illustrative application, we also consider probabilistic preference aggregation. Finally, we compare our results with existing results on binary judgment aggregation and Arrovian preference aggregation. This paper is the first of two self-contained, but technically related companion papers inspired by binary judgment-aggregation theory. (shrink)

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

In this paper, we identify a new and mathematically well-defined sense in which the coherence of a set of hypotheses can be truth-conducive. Our focus is not, as usual, on the probability but on the confirmation of a coherent set and its members. We show that, if evidence confirms a hypothesis, confirmation is “transmitted” to any hypotheses that are sufficiently coherent with the former hypothesis, according to some appropriate probabilistic coherence measure such as Olsson’s or Fitelson’s measure. Our findings have (...) implications for scientific methodology, as they provide a formal rationale for the method of indirect confirmation and the method of confirming theories by confirming their parts.

Computer-simulated scenarios have been part of psychological research on problem solving for more than 40 years. The shift in emphasis from simple toy problems to complex, more real-life oriented problems has been accompanied by discussions about the best ways to assess the process of solving complex problems. Psychometric issues such as reliable assessments and addressing correlations with other instruments have been in the foreground of these discussions and have left the content validity of complex problem solving in the background. In (...) this paper, we return the focus to content issues and address the important features that define complex problems. (shrink)

In judgment aggregation, unlike preference aggregation, not much is known about domain restrictions that guarantee consistent majority outcomes. We introduce several conditions on individual judgments su¢ - cient for consistent majority judgments. Some are based on global orders of propositions or individuals, others on local orders, still others not on orders at all. Some generalize classic social-choice-theoretic domain conditions, others have no counterpart. Our most general condition generalizes Sen’s triplewise value-restriction, itself the most general classic condition. We also prove a (...) new characterization theorem: for a large class of domains, if there exists any aggregation function satisfying some democratic conditions, then majority voting is the unique such function. Taken together, our results provide new support for the robustness of majority rule. (shrink)

Recent theoretical and empirical work in cognitive science and neuroscience is brought into contact with the concept of the flow experience. After a brief exposition of brain function, the explicit–implicit distinction is applied to the effortless information processing that is so characteristic of the flow state. The explicit system is associated with the higher cognitive functions of the frontal lobe and medial temporal lobe structures and has evolved to increase cognitive flexibility. In contrast, the implicit system is associated with the (...) skill-based knowledge supported primarily by the basal ganglia and has the advantage of being more efficient. From the analysis of this flexibility/efficiency trade-off emerges a thesis that identifies the flow state as a period during which a highly practiced skill that is represented in the implicit system’s knowledge base is implemented without interference from the explicit system. It is proposed that a necessary prerequisite to the experience of flow is a state of transient hypofrontality that enables the temporary suppression of the analytical and meta-conscious capacities of the explicit system. Examining sensory-motor integration skills that seem to typify flow such as athletic performance, writing, and free-jazz improvisation, the new framework clarifies how this concept relates to creativity and opens new avenues of research.

: Where there are cases of underdetermination in scientific controversies, such as the case of the molecular clock, scientists may direct the course and terms of dispute by playing off the multidimensional framework of theory evaluation. This is because assessment strategies themselves are underdetermined. Within the framework of assessment, there are a variety of trade-offs between different strategies as well as shifting emphases as specific strategies are given more or less weight in assessment situations. When a strategy is underdetermined, scientists (...) can change the dynamics of a controversy by making assessments using different combinations of evaluation strategies and/or weighting whatever strategies are in play in different ways. Following an underdetermination strategy does not end or resolve a scientific dispute. Consequently, manipulating underdetermination is a feature of controversy dynamics and not controversy closure.

The neutral and nearly neutral theories of molecular evolution are sometimes characterized as theories about drift alone, where drift is described solely as an outcome, rather than a process. We argue, however, that both selection and drift, as causal processes, are integral parts of both theories. However, the nearly neutral theory explicitly recognizes alleles and/or molecular substitutions that, while engaging in weakly selected causal processes, exhibit outcomes thought to be characteristic of random drift. A narrow focus on outcomes obscures the (...) significant role of weakly selected causal processes in the nearly neutral theory. (shrink)

How can different individuals' probability functions on a given sigma-algebra of events be aggregated into a collective probability function? Classic approaches to this problem often require 'event-wise independence': the collective probability for each event should depend only on the individuals' probabilities for that event. In practice, however, some events may be 'basic' and others 'derivative', so that it makes sense first to aggregate the probabilities for the former and then to let these constrain the probabilities for the latter. We formalize (...) this idea by introducing a 'premise-based' approach to probabilistic opinion pooling, and show that, under a variety of assumptions, it leads to linear or neutral opinion pooling on the 'premises'. This paper is the second of two self-contained, but technically related companion papers inspired by binary judgment-aggregation theory. (shrink)

There has been much discussion on the two-envelope paradox. Clark and Shackel (2000) have proposed a solution to the paradox, which has been refuted by Meacham and Weisberg (2003). Surprisingly, however, the literature still contains no axiomatic justification for the claim that one should be indifferent between the two envelopes before opening one of them. According to Meacham and Weisberg, "decision theory does not rank swapping against sticking [before opening any envelope]" (p. 686). To fill this gap in the literature, (...) we present a simple axiomatic justification for indifference, avoiding any expectation reasoning, which is often considered problematic in infinite cases. Although the two-envelope paradox assumes an expectation-maximizing agent, we show that analogous paradoxes arise for agents using different decision principles such as maximin and maximax, and that our justification for indifference before opening applies here too.

Using an analogy between moths and men, in 1916, Richard Goldschmidt proposed that homosexuality was a case of genetic intersexuality. As he strove to create a unified theory of sex determination that would encompass animals ranging from moths to men, Goldschmidt's doubts grew concerning the association of homosexuality with intersexuality until, in 1931, he dropped homosexuality from his theory of intersexuality. Despite Goldschmidt's explicit rejection of his theory of homosexuality, Theo Lang, a researcher in the Genealogical-Demographic Department of the Institute (...) for Psychiatric Research in Munich, revived it, maintained Goldschmidt's association with it, and argued on its behalf in publications from 1936 to 1960. Lang's appropriation of Goldschmidt's theory did not depend on his resolution of the difficulties Goldschmidt had found with his own theory. Lang and Goldschmidt, I argue, had fundamentally different scientific and social commitments that allowed one to reject this theory of homosexuality and the other to accept it. (shrink)

Scientific explanation is both instrumental and consummatory. When we experience scientific explanation in its consummation, we experience what I have deemed a creative moment of scientific apprehension, which is an important aspect of creativity that comes at the end of inquiry and contributes to the development of future inquiry. Because scientific explanation is commonly cleaved from aesthetic experience, this moment of creativity has been neglected in both analyses of scientific practice and analyses of aesthetic experience. By synthesizing John Dewey’s conceptions (...) of scientific explanation and aesthetic experience with Charles S. Peirce’s categories, this moment of scientific inquiry is revealed and understood as a fundamental part of our creative reasoning process. In order to argue that scientific explanation is both instrumental and consummatory, Dewey’s instrumental conception of scientific explanation is provided, which includes why science is so often considered as separated from aesthetic experience. A general overview of Dewey’s conception of aesthetic experience and the common division conceived between scientific experience and that of aesthetics is also provided. Reasons are then supplied to reconsider scientific experience as having an aesthetic dimension, especially with regard to scientific explanations and the creative moment of scientific apprehension, which is followed by a brief discussion concerning how recognition of this moment reveals an important aspect of creative reasoning that is to be understood as a part of our experience through what Peirce referred to as firstness and secondness. Analyzing the aesthetic experience of scientific explanations against the backdrop of Dewey’s conceptions of aesthetics and science, combined with Peirce’s categories, accounts for that creative moment of scientific apprehension in which a scientific explanation takes on the quality of kalos, or sense of general harmony, that inspires reverie and future inquiry.

Throughout the 1930s two of Germany’s most senior geneticists were caught up in controversy as they tried to enter the distinctly American culture of Drosophila genetics. When Richard Goldschmidt and Victor Jollos were forced by the Nazis to leave Germany in 1936 and 1933, respectively, this type of conflict intensified. The experiences of Goldschmidt and Jollos as émigré scientists are interpreted in terms of a conflict of scientific styles of thought. Their Americanization, I claim, involved the modification of their scientific (...) styles and consequently the ways in which they conceived of and presented their scientific work. (shrink)

Zusammenfassung Die im Dezember 2022 in Kraft getretene Erweiterung des Infektionsschutzgesetzes sieht vor, im Fall einer Pandemie knappe intensivmedizinische Ressourcen nach dem Kriterium der Überlebenswahrscheinlichkeit zu priorisieren. Der Aufsatz geht der Frage nach, ob der Vorwurf, diese Regelung setze Menschen mit Behinderung einer erheblichen Diskriminierungsgefahr aus, berechtigt ist. Nach einer kurzen Darstellung des im Infektionsschutzgesetz festgelegten Zuteilungsverfahrens wird zunächst das vielschichtige Konzept der Diskriminierung erörtert. Im Kontext der Allokation knapper intensivmedizinischer Ressourcen besteht vornehmlich das Risiko einer nichtintendierten Diskriminierung, die in (...) direkter wie auch indirekter Form erfolgen kann. Die Regelungen, die das Infektionsschutzgesetz trifft, bieten Menschen mit Behinderung einen vergleichsweise hohen Schutz vor direkter Diskriminierung. Dennoch müssen Menschen mit bestimmten Behinderungen gravierende Nachteile hinnehmen, weil sie im Fall einer COVID-19-Infektion absehbar eine geringere Überlebenswahrscheinlichkeit als gesunde Menschen haben. Eine indirekte Diskriminierung liegt aber nur dann vor, wenn für die Auferlegung disproportionaler Nachteile keine hinreichende Rechtfertigung angeführt werden kann. In modernen pluralistischen Gesellschaften, die durch tiefgreifende Wertkonflikte gekennzeichnet sind, sollten unterschiedliche ethische Theorien – darunter auch konsequentialistische Positionen – als mögliche Grundlage einer Rechtfertigung anerkannt werden. Im Ergebnis erweist sich der Vorwurf, eine am Kriterium der Überlebenswahrscheinlichkeit orientierte Zuteilung knapper intensivmedizinischer Ressourcen bewirke eine Diskriminierung von Menschen mit Behinderung, als nicht stichhaltig.
