Die vorliegende Schrift unternimmt eine Revision des vorherrschenden Bildes der Rolle und der Konzeptionen von Moral und Ethik im Wiener Kreis. Dieses Bild wird als zu einseitig und undifferenziert zurückgewiesen. Die Ansicht, die Mitglieder des Wiener Kreises hätten kein Interesse an Moral und Ethik gezeigt, wird widerlegt. Viele Mitglieder waren nicht nur moralisch und politisch interessiert, sondern auch engagiert. Des Weiteren vertraten nicht alle die Standardauffassung logisch-empiristischer Ethik, die neben der Anerkennung deskriptiv-empirischer Untersuchungen durch die Ablehnung jeglicher normativer und inhaltlicher (...) Ethik und der Verfechtung eines extremen Nonkognitivismus geprägt ist. Am meisten entspricht die Standardauffassung den Ansichten Rudolf Carnaps, weniger bereits jenen Karl Mengers, Otto Neuraths oder Philipp Franks. Am weitesten weichen Moritz Schlick, Victor Kraft sowie Herbert Feigl von der Standardauffassung ab. Entgegen dem herkömmlichen Bild weltabgewandter Logiker und Metaethiker wurde im Wiener Kreis sogar Angewandte Ethik betrieben, und dies bereits unter diesem Namen. Neben den ethischen Hauptthemen und Ansichten der jeweiligen Philosophen in ihrer Entwicklung im Rahmen ihres persönlichen und kulturellen Kontextes zeigt die Untersuchung, dass allen Ansätzen eine aufgeklärte und humanistische Version von Moral und Ethik gemeinsam ist. Dieser wissenschaftliche Humanismus, der sich schon in der Programmschrift Wissenschaftliche Weltauffassung. Der Wiener Kreis findet, liegt jedoch in verschiedenen Ausprägungen vor. Was die Abweichungen von der Standardauffassung wesentlich betrifft, ist ihre unterschiedliche Auffassung von Moral als gemeinsames oder individuelles Unternehmen. Carnap führt ein extremer Individualismus zu einem extremen Nonkognitivismus, in dem ihm Menger folgt. Bei Schlick ist die Lage zweideutig, was sich in unterschiedlichen Moralbegriffen widerspiegelt. Bei Kraft und Feigl tritt das Verständnis von Moral als gemeinschaftlich geteilte Praxisform klar hervor. Auf der Basis eines gemeinsamen Begriffs des moralisch Guten, der auch eine Sachkomponente enthält, ist eine Verständigung über moralische Fragen möglich. Von einem extremen Nonkognitivismus kann dort nicht mehr die Rede sein. Mit diesen Ergebnissen verbietet es sich, dem Wiener Kreis allgemein eine Ablehnung normativer Ethik und einen extremen Nonkognitivismus zuzuschreiben. Eine systematische Ethik, die Moral als Gemeinschaftspraxis begreift, steht einigen im Wiener Kreis näher, als das vorherrschende Bild suggerieren möge. Wer meint, mit engem Bezug zur Tradition des Wiener Kreises nur Carnap folgen zu können und Ethik als suspektes Unternehmen betrachten zu müssen, irrt. Ethik war in der Tradition Analytischer Philosophie nicht immer so marginalisiert, wie sie es in manchen ihrer Teilrichtungen heute noch ist und Gegner(innen) der Analytischen Philosophie vorwerfen. Die vorliegende Untersuchung liefert die nötige Revision einer verfänglichen Fehlentwicklung. (shrink)

Economic markets are not morally free zones. Contrary to popular misconceptions, market functioning rests on the ethical principles of fairness and voluntariness. This ethical foundation can be traced back at least to moral philosopher Adam Smith, one of the founders of modern economics. In the inconspicuous form of microeconomic axioms, these moral foundations are preserved. Thus, virtually all “neo-classic” economic concepts presuppose a market ethics of fairness and voluntariness. In a world of pervasive uncertainty on the long-term development of the (...) human-environment interaction, the protection of the global life-support systems is an important test case for the scope of the ethical content of market ethics. We review risk protection strategies in the face of this uncertainty that are (i) based on the insurance effect of biological diversity, and (ii) that employ a safe minimum standard (SMS). Because the fairness principle of market ethics requires that economic agents who cause “external” costs must, at least, compensate those who are burdened with these costs, the interests of future generations have to be included in responsible economic decision-making. The market and market ethics approach is applied to the analysis of a SMS for biological diversity, and to the inherent problems of such an approach. At the microeconomic level of individual decision-making, an unconditional protection is supported by market ethics neither for the putative interests of future generations nor for biological diversity: Poor people who struggle to cover their basic needs cannot not be required to care for biological diversity. In all other cases, the protection of biological diversity in favour of future generations is supported—if costs are not “unacceptably high”. At which cost level this point is approached, market ethics is not designed to decide. (shrink)

Economic environmental valuation remains a much debated and contested issue. Concerns have been voiced that it is unable to capture the manifold immaterial values of ecosystems due to conceptual and methodological issues. Thus, additional value categories (social values) as well as novel valuation approaches like deliberative (monetary) valuation are areas of growing interest, yet the theoretical foundations are rather weak. Against this background, this article aims to develop a consistent conceptual framework for making sense of social values in economic environmental (...) valuation. Based on a holistic view of society and individuals, the role of institutions, the social environment, culture and transcendental values is emphasised. To synthesise diverging concepts of value into an economic concept and to account for the multidimensionality of social values, the framework consists of three spheres: social, natural and contextual. The novel framework demonstrates that social values may be integrated into a preference-based utility framework when denoting a holistic understanding of social preferences and human embeddedness in nature and society.

With the cost-benefit analysis, economists cultivate a specific decision-making procedure that is also partially accepted in politics. The objections raised in the tradition of criticizing utilitarianism and against the economization of decision-making, such as the criticism of balancing, of an allegedly lack of distributive justice, or of the tendency to describe human beings in behavioral scientific terms as self-interested, are, however, hardly convincing upon closer examination. But first, the empiricist theoretical basis of (covertly normative) cost-benefit analysis seems untenable. This refers (...) to its idea that normative questions have to be transformed into questions of factual preferences. Second, there are massive collisions with a liberal-democratic constitutional law whose principles are at the same time basic ethical principles. This concerns both the rights of freedom (which must not depend on the ability to pay) and the model of democracy and respect for the rule of law. Third, there are insoluble application problems for cost-benefit analysis, which becomes visible especially (but not only) in the context of climate protection, both in overall considerations and in individual analyses, such as the construction of a coal-fired power plant.

Using the mathematical frameworks of economic preference ranking, subjective probability, and rational learning through empirical evidence, the epistemological implications of teleological ethical intuitionism are pointed out to the extent to which the latter is based on cognitivist and objectivist concepts of value. The notions of objective value and objective norm are critically analysed with reference to epistemological criteria of intersubjectively shared valuative experience. It is concluded that one cannot meaningfully postulate general material theories of morality that could be tested, confirmed (...) or refuted by intersubjective empirical evidence of preferences and values, however loosely the empirical evidence of values may be interpreted. This situation is explained with reference to the ways in which preceived values become systematically influenced by the concomitants of individual valuative experience, but which have nothing to do with contingent subjective interests.

The Ontological Dilemma of Normative Ethics. This paper pursues two goals. The first is to show that normative ethics is confronted with the following dilemma: to be coherent, this discipline is ontologically committed to acknowledge the existence of objective values, but, to be scientifically respectable, it is committed to repudiate such values. The second goal is to assess the possible solutions to this dilemma. To this end, the following strategies are discussed: Kant’s constructive objectivism, Jürgen Habermas’ “epistemic ersatzism”, Franz von (...) Kutschera’s “confirmation pragmatism”, and David Brink’s “objectivist tour de force”. The paper’s conclusion is that the dilemma cannot be solved because it rests on a clash of intuitions none of which can be given up. (shrink)

This paper presents an outline of a new theory of relevant deduction which arose from the purpose of solving paradoxes in various fields of analytic philosophy. In distinction to relevance logics, this approach does not replace classical logic by a new one, but distinguishes between relevance and validity. It is argued that irrelevant arguments are, although formally valid, nonsensical and even harmful in practical applications. The basic idea is this: a valid deduction is relevant iff no subformula of the conclusion (...) is replaceable on some of its occurrences by any other formula salva validitate of the deduction. The paper first motivates the approach by showing that four paradoxes seemingly very distant from each other have a common source. Then the exact definition of relevant deduction is given and its logical properties are investigated. An extension to relevance of premises is discussed. Finally the paper presents an overview of its applications in philosophy of science, ethics, cognitive psychology and artificial intelligence. (shrink)

The distinction between teleology and deontology is today almost universally accepted within practical philosophy, but deontology is and has from the beginning been subordinate to utili-tarianism. ‘Deontology’ was constructed by Bentham to signify the art and science of private morality within a utilitarian worldview. The classical distinction was constructed by Broad as a refinement of Sidgwick’s utilitarianism, and then adopted by Frankena. To Broad it signified two opposite tendencies in ethics, in Frankena’s textbooks, however, it becomes an exclusive distinction, where (...) de-ontology signifies disregard for consequences, and it is therefore almost impossible to think of deontology as a framework for a com-prehensive ethical theory. This conception, however, is adopted by Rawls, and in his contractarian interpretation of deontology it is in fact no more within the sphere of ethics. (shrink)

This paper makes an attempt at the conceptual foundation of descriptive ethical theories in terms of evolutionary anthropology. It suggests, first, that what human social actors tend to accept to be morally valid and legitimate ultimately rests upon empirical authority relations and, second, that this acceptance follows an evolved pattern of hierarchical behaviour control in the social animal species. The analysis starts with a brief review of Thomas Hobbes'' moral philosophy, with special emphasis on Hobbes'' authoritarian view of moral validity (...) and of the common political origins and ultimate basis of legitimacy of moral and legal systems. Hobbes'' philosophical conceptions are then put into the context of Max Weber''s influential empirical theory of legitimacy, especially charismatic revelation and authority as the ultimate source of all moral, legal and religious obligations. Weber''s concept of charismatic authority is given a biobehavioural interpretation in terms of ritualised status signals indicating an individual''s superior physical and emotional dispositions to control the social actions of others. Various conclusions are drawn concerning the concept of moral validity and its possible evolutionary interpretations. (shrink)

Using concepts of evolutionary game theory, this paper presents a critique of ethical intuitionism, or non-naturalism, in its cognitivist and objectivist interpretation. While epistemological considerations suggest that human rational learning through experience provides no basis for objective moral knowledge, it is argued below that modern evolutionary theory explains why this is so, i.e., why biological organisms do not evolve so as to experience objective preferences and obligations. The difference between the modes of the cognition of objective and of valuative environmental (...) attributes is explained with reference to different modes of natural selection acting on the cognitive apparatus of the organism. The negative implications are pointed out which the observable diversity of intraspecific behavioural adaptations and of cultural values has for the cognitivist, objectivist foundation of ethics. Eventually a non-cognitivist alternative to ethical intuitionism is outlined in terms of empirical authority relations, with the ritualisation of dominance-submission patterns as the evolutionary origin of human charismatic authority.

In this essay, we will try to provide a formal analysis of practical inference, attentive to the various phases in which it is articulated, and being so capable of explaining both the logical conclusiveness of the inference and the probabilistic nature of its conclusion. An innovative purpose of this article is to show how the final deliberation leading to action—the ultimate practical judgment—takes place according to a logic consistent with the use of Bayes’ theorem. This is why we refer to (...) Bayesian practical inference in the title of this essay. (shrink)
