This paper attempts to show how leading contemporary disciplines influenced the discovery of Chagas' disease and the formation of the early disease concept. Chagas was among the first generation of Brazilian trained scientists who incorporated modern principles of tropical medicine in its research. Thus, Chagas was familiar with characteristics of vector borne tropical diseases such as malaria and yellow fever. The detection of a hitherto unknown trypanosome in the gut of a reduviid bug prompted him to search for a related (...) vector borne disease. Among the disciplines that were influential on Chagas' discovery and early disease description were pathology, entomology and parasitology. Parasitology as a new discipline was of crucial importance to tropical medicine and had a political dimension in the context of colonial medicine. Hence, leading scientists in tropical medicine were located in European countries and in the United States of America. One of these was the German Schaudinn School of Protozoology. The early description of American Trypanosomiasis can also be seen as a reflection of the Schaudinn School of Protozoology which dominated Chagas' scientific orientation towards parasitology with regard to the interpretation of the observed phenomena of the life cycle and the morphology and biology of T. cruzi. The first Chagas' disease concept was based on research of the biology and entomology of the trypanosome and its vector as well as on pathological studies of fatal cases. This concept was characterized by a confusion of some of the chronic forms of the disease, as iodine deficiency and goitre were endemic in some rural regions in Brazil. Therefore, early concepts of the disease faced strong opposition and even raised doubts about its existence. (shrink)

Was macht das Besondere der menschlichen Lebensform aus? Wie können wir es verstehen, dass unsere Art wie alle anderen natürlich evolviert ist und dennoch als einzige Art die Fähigkeit entwickelt hat, unter dem Anspruch der Freiheit und in reflexiver Distanz zu handeln, damit aber die Umwelt auf eine Welt hin zu transzendieren? Jung argumentiert, dass sich diese Fragen nur beantworten lassen, wenn man philosophische, evolutionstheoretische und kognitionswissenschaftliche Ansätze aufeinander bezieht. Der Schlüssel hierfür ist der Begriff der Bedeutung. Alle Lebewesen erfassen (...) ihre Umwelt im praktischen Umgang mit ihr als bedeutsam. Auch der Geist des Menschen ist essentiell verkörpert und basiert auf erlebten Bedeutsamkeiten. Die Fähigkeit zur symbolischen Artikulation und kulturellen Weiterentwicklung solcher Lebensbedeutungen erlaubt es ihm aber auch, die lokale Umwelt zu transzendieren und dabei Werte, Normen und objektive Geltungsansprüche zu entwickeln. Eine zeitgemäße Anthropologie muss in der Lage sein, diese qualitativen Besonderheiten des menschlichen Geistes als Resultate von Naturprozessen verständlich zu machen. Sie verbindet methodischen Naturalismus mit Offenheit für die Transzendenz des Geistes über die Umwelt. Damit leistet der Autor einen wichtigen Beitrag zu einem nichtreduktionistischen Verständnis des Menschen, das Leib und Geist nicht dualistisch trennt, sondern ihre spannungsvolle Einheit sichtbar macht.

This paper defends the normativity of meaning thesis by clearing up a misunderstanding about what the thesis amounts to. The misunderstanding is that according to it, failing to use an expression in accordance with the norms which constitute its meaning amounts to changing the expression’s meaning. If this was what the thesis claimed, then it would indeed be easy to show that meaning norms do not yield prescriptions and cannot be followed. However, there is another reading: what is constitutive of (...) meaning is not the norm’s being followed, but the norm’s being applicable. On this reading, some standard arguments against the thesis lose their force. After discussing the alternative reading and its consequences, the paper goes on to sketch a model of how norms of meaning become applicable in the first place. This model supports the view that talk of meaning has its pragmatic home in contexts of linguistic calibration. (shrink)

Wir möchten der Charter on Medical Professionalism, die wir für vorbildlich halten, eine durchdachte Anreicherung hinzufügen. Wir beginnen mit einer skeptischen Note gegen das verbreitete theoretische Vorurteil, die wichtigsten Probleme im Gesundheitssystem seien Gerechtigkeitsprobleme und diese seien theoretisch gut beherrschbar. Unter Bezug auf Norman Daniels, der John Rawls’ Theorie der politischen Gerechtigkeit auf die Bewertung und Gestaltung von Gesundheitssystemen anwendet, sowie auf die biomedizinische Ethik, die von Beauchamp und Childress vertreten wird, analysieren wir das komplexe Verhältnis zwischen moralischer Integrität von (...) Strukturen und Organisationen einerseits und natürlichen Personen, die in ihnen arbeiten, andererseits. Anschließend interpretieren wir die Charta als eine Spezifizierung der ärztlichen professionsmoralischen Verantwortung auf mehreren Ebenen, die Tugend- und Organisationsethik verklammern. (shrink)

This paper argues that ceteris paribus (cp) laws exist based on a Lewisian best system analysis of lawhood (BSA). Furthermore, it shows that a BSA faces a second trivialization problem besides the one identified by Lewis. The first point concerns an argument against cp laws by Earman and Roberts. The second point aims to help making some assumptions of the BSA explicit. To address the second trivialization problem, a restriction in terms of natural logical constants is proposed that allows one (...) to describe regularities, as specified by basic generics (e.g. ‘birds can fly’) and universals (e.g. ‘all birds can fly’). It is argued that cp laws rather than strict laws might be a part of the the best system of such a regularity-based BSA, since sets of cp laws can be both (a) simpler and (b) stronger when reconstructed as generic non-material conditionals. Yet, if sets of cp laws might be a part of the best system of a BSA and thus qualify as proper laws of nature, it seems reasonable to conclude that at least some cp laws qualify as proper laws of nature.

Freges Kontextprinzip "Nur im Zusammenhange eines Satzes bedeuten die Wörter etwas" hat auch nach der von ihm vollzogenen Angleichung von Behauptungssätzen an Eigennamen Gültigkeit für die formale Sprache der "Grundgesetze". Der Bedeutungsvollständigkcitsbeweis, den er für sein Logiksystem anstrebt, schließt eine unmittelbare Anwendung dieses Prinzips nicht nur auf die unvollständigen Funktionsausdrücke, sondern auch auf die leerstellenfreien Wertverlaufsnamen ein. Wahrheitsnamen (Sätze) zeichnen sich vor anderen symbolsprachlichen Eigennamen in mehrfacher Hinsicht, insbesondere durch ihre semantische Selbständigkeit aus. Wertverlaufsnamen haben nur im Zusammenhang eines Wahrheitswertnamens (...) eine Bedeutung. Ihre Bedeutung besteht in ihrem Beitrag zur Bestimmung der Bedeutung von Wahrheitswertnamen, in denen sie vorkommen. (shrink)

Neo-logicism is, not least in the light of Frege’s logicist programme, an important topic in the current philosophy of mathematics. In this essay, I critically discuss a number of issues that I consider to be relevant for both Frege’s logicism and neo-logicism. I begin with a brief introduction into Wright’s neo-Fregean project and mention the main objections that he faces. In Sect. 2, I discuss the Julius Caesar problem and its possible Fregean and neo-Fregean solution. In Sect. 3, I raise (...) what I take to be a central objection to the position of neo-logicism. In Sect. 4, I attempt to clarify how we should understand Frege’s stipulation that the two sides of an abstraction principle qua contextual definition of a term-forming operator shall be “gleichbedeutend”. In Sect. 5, I consider the options that Frege might have had to establish the analyticity of Hume’s Principle: The number that belongs to the concept F is equal to the number that belongs to the concept G if and only if F and G are equinumerous. Section 6 is devoted to Frege’s two criteria of thought identity. In Sects. 7 and 8, I defend the position of the neo-logicist against an alleged “knock-down argument”. In Sect. 9, I comment on Frege’s description of abstraction in Grundlagen, §64 and the use of the terms “recarving” and “reconceptualization” in the relevant literature on Fregean abstraction and neo-logicism. I argue that Fregean abstraction has nothing to do with the recarving of a sentence content or its decomposition in different ways. I conclude with remarks on global logicism versus local logicisms.

(2013). Critical notice of Aaron James, Fairness in Practice: A Social Contract for a Global Economy. Canadian Journal of Philosophy: Vol. 43, No. 3, pp. 382-401.

During the fall of 2001 (October 22–25), The Norwegian Radiation Protection Authority (NRPA) and the Agricultural University of Norway arranged a consensus conference on the protection of the environment against ionising radiation. The motive for the conference was the need to study the ethical and philosophical basis for protection of nature in its own right. The conference was funded by Nordic Nuclear Safety Research (NKS), in cooperation with the International Union of Radioecology (IUR). The National Committee for Research Ethics in (...) Science and Technology (NENT) was hired as facilitators for the consensus process. This paper will give a brief outline of the aims and method of the conference, distinguishing these from other kinds of consensus conferences. The paper ends with some general reflections on the appropriateness of seeking consensus on ethics-related issues among experts. (shrink)

The integration of ethics into the day-to-day work of research and innovation is an important but difficult challenge. However, with the Aachen method for identification, classification and risk analysis of innovation-based problems an approach from an engineering perspective is presented that enables the integration of ethical, legal and social implications into the day-to-day work of R&I practitioners. AMICAI appears in particular capable of providing a procedural guidance for R&I practitioners based on a method established in engineering science, breaking down the (...) object of consideration into partial aspects and prioritizing the innovation-based problems in dependence of potential risk. This enables the user to apply AMICAI continuously during all stages of the research and development process and to analyze and choose between certain sociotechnical alternatives. In this way, problems that affect ethical, legal, and social aspects can be understood, reflected and considered in the mostly technically focused R&D process. The paper gives a general guidance about AMICAI by describing principles and assumptions, providing the steps of analysis and application aids, giving an example application, explaining the necessary adjustments of AMICAI compared to the methodical basis of failure mode, effects, and criticality analysis and discussing the advantages and limits. AMICAI’s simple applications can stimulate interdisciplinary cooperation in the R&D process and be a starting point for the development of an “open RRI risk analysis platform” allowing society to evaluate innovation-based problems.
