    An Epistemological Appraisal of Walton’s Argument Schemes
    Informal Logic 44 (1): 203-290. 2022.
    The article critically discusses Walton’s (and co-authors’) argument scheme approach to good argumentation. Four characteristics of Walton’s approach are presented: 1. Argument schemes provide normative requirements. 2. These schemata are enthymematic. 3. There are associated critical questions. 4. The method is inductive, abstracting schemata from groups of similar arguments. Four adequacy conditions are applied to these characteristics: AC1: effectiveness in achieving the epistemic goal of obt…Read more

    Justifying the Epistemological Theory of Argumentation
    Informal Logic 44 (1): 574-600. 2024.
    This article discusses Harvey Siegel’s general justification of the epistemological theory of argumentation in his seminal essay “Arguing with Arguments." On the one hand, the achievements of this essay are honoured—in particular, a thorough differentiation of the different meanings of ‘argument’ and ‘argumentation,’ the semantic justification of the fundamentality of arguments as sequences of propositions, and the detailed critiques of alternative theories of argumentation. On the other hand, s…Read more

    The Relevance of Skovoroda's Ethical Principles. Skovoroda's Discussion of Real Happiness
    Journal of V. N. Karazin Kharkiv National University, Series Philosophy: Philosophical Peripeteias 67 87-91. 2022.
    The article honours the contribution of the Ukrainian philosopher Hryhoriy Skovoroda on the occasion of his 300th birthday on 9 October 2022. It begins with an address of solidarity to the Ukrainians and the Ukrainian philosophers in their fight against the Russian invaders who had bombed and destroyed the Skorovoda Museum in Kharkov shortly before this birthday. The article's main part is an analysis of Skovoroda's theory of happiness in his writing "Conversation Among Five Travellers Concerni…Read more

    Strikter Pazifismus oder Wahl der besten Alternative?
    Zeitschrift für Philosophische Forschung 77 (2): 210-216. 2023.
    In seinem Buch Pazifismus. Eine Verteidigung verteidigt Olaf Müller einen relativ strikten Pazifismus, der im Ukrainekrieg keine militärische Hilfe an die Ukraine erlaubt ‐ trotz der Anerkennung, dass es sich um einen verbrecherischen Angriffskrieg handelt. Müller kritisiert die beiden üblichen Begründungen für solch eine Position, den gesinnungsethischen und den verantwortungsethischen Pazifismus, und entwickelt seine eigene Version, den pragmatistischen Pazifismus.Der vorliegende Beitrag disku…Read more

    Norms of Public Argumentation and the Ideals of Correctness and Participation
    with Frank Zenker, Jan Albert van Laar, B. Cepollaro, A. Gâţă, M. Hinton, C. G. King, B. Larson, M. Lewiński, S. Oswald, M. Pichlak, B. D. Scott, M. Urbański, and J. H. M. Wagemans
    Argumentation 38 (1): 7-40. 2024.
    Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principl…Read more

    Epistemic Norms for Public Political Arguments
    Argumentation 38 (1): 63-83. 2024.
    The aim of the article is to develop precise epistemic rules for good public political arguments, by which political measures in the broad sense are justified. By means of a theory of deliberative democracy, it is substantiated that the justification of a political measure consists in showing argumentatively that this measure most promotes the common good or is morally optimal. It is then discussed which argumentation-theoretical approaches are suitable for providing epistemically sound rules fo…Read more

    La funzione morale della democrazia deliberativa
    In Raffaela Giovagnoli (ed.), Etica E Politica, Clarendon Press. pp. 185-199. 1996.
    The article develops and defends, with a detailed argument, a certain moral-instrumentalist conception of deliberative democracy according to which, so the main thesis, a certain form of deliberative democracy is the best means for the binding realisation of moral values. This conception combines an epistemic component, according to which deliberation serves to determine which measures most serve the general good, with a participatory component, according to which democratic voting serves to giv…Read more

    An Epistemological Appraisal of Walton’s Argument Schemes
    Informal Logic 43 (4): 203-290. 2022.
    Abstract: The article presents and critically discusses Walton's (and Reed's and Macagno's) argument scheme approach to a theory of good argumentation. In particular, four characteristics of Walton's approach are presented: 1. It presents normative requirements for argumentation in the form of argument schemes, i.e. relatively concrete type descriptions. 2. These schemata are enthymematic, i.e. they omit some of the premises required by other approaches. 3. The actual argument schemes are usuall…Read more

    In this paper, first the term 'prioritarianism' is defined, with some mathematical precision, on the basis of intuitive conceptions of prioritarianism, especially the idea that "benefiting people matters more the worse off these people are". (The prioritarian weighting function is monotonously ascending and concave, while its first derivation is smoothly descending and convex but positive throughout.) Furthermore, (moderate welfare) egalitarianism is characterized. In particular a new symmetry c…Read more

    The article develops an internalist justification of welfare ethics based on empathy. It takes up Hume’s and Schopenhauer’s internalistic (but not consistently developed) justification approach via empathy, but tries to solve three of their problems: 1. the varying strength of empathy depending on the proximity to the object of empathy, 2. the unclear metaethical foundation, 3. the absence of a quantitative model of empathy strength. 1. As a solution to the first problem, the article proposes …Read more

    Berechnungen der moralischen Effizienz
    In Johannes L. Brandl, Daniel Messelken & Sava Wedman (eds.), Denken. Reden. Handeln. / Thinking. Talking. Acting. Nachträge zu einem Salzburger Symposium mit Georg Meggle, Open Access Publikationsserver Der Universität Salzburg (eplus). pp. 565-574. 2021.
    English: Effective altruism has focused on moral efficiency, i.e. the ratio of the resources used (money, time ...) to the moral benefit achieved, in addition to the extent of our moral commitment, and has called for the maximum efficiency of moral commitment. This raises two questions, among others, which are the subject of this paper: 1. How does one calculate moral efficiency? 2. Is maximum moral efficiency the right moral decision-making criterion? In the article, efficiency calculations of …Read more

    This is an appendix to the article "Wie effizient sollten Altruisten handeln?" ("How Efficient Should Altruists Act?") The appendix provides detailed moral efficiency calculations for two charitable projects: a children's home in Guatemala for neglected children versus malaria prevention by distributing mosquito nets in malaria areas in sub-Saharan Africa. The exact method of efficiency calculation is explained and applied. At least prima facie, the malaria prophylaxis project is clearly more ef…Read more

    The article develops a general theory of the goals of free moral commitment. The theoretical hook is the discussion of the strict efficiency striving as demanded by the movement and theory of effective altruism. A detailed example shows prima facie counterintuitive consequences of this efficiency striving, the analysis of which reveals various problems such as: merely point-like but not structural commitment; radical universalism; violation of established moral standards and institutions. The ar…Read more

    Präferenzen, Nutzen und ihre Aggregation
    In Christian Hiebaum (ed.), Interdisziplinäres Handbuch "Gemeinwohl", Springer Fachmedien. pp. 177-193. 2021.
    Desire', 'preference', 'utility', '(utility-aggregating) moral desirability' are terms that build on each other in this order. The article follows this definitional structure and presents these terms and their justifications. The aim is to present welfare-ethical criteria of the common good that define 'moral desirability' as an aggregation, e.g. addition, of individual utility: utilitarianism, utility egalitarianism, leximin, prioritarianism.

    RATIONAL ALTRUISM. A PRUDENTIAL THEORY OF RATIONALITY AND ALTRUISM - STRUCTURE: "Rational altruism" is the attempt to develop and rationally justify moral principles - with a very strong emphasis on this justification. The concept of justification is developed in a metaethical part (ch. 2); it requires recourse to prudential decisions and to information about our decision-making procedures. The actual normative ethics (Ch. 6 and especially 7) is therefore still based on a prudential desirabilit…Read more

    The Greenhouse: A Welfare Assessment and Some Morals
    University Press of America. 2002.
    In this book some options concerning the greenhouse effect are assessed from a welfarist point of view: business as usual, stabilization of greenhouse gas emissions and reduction by 25% and by 60%. Up to today only economic analyses of such options are available, which monetize welfare losses. Because this is found to be wanting from a moral point of view, the present study welfarizes (among others) monetary losses on the basis of a hedonistic utilitarianism and other, justice incorporating, wel…Read more

    ACTION-THEORETICALLY EXPLANATORY INTERPRETATIONS AS A MEANS OF SEMANTIC MEANING ANALYSIS The article first develops a general procedure for semantic meaning analysis in difficult cases where the meaning is very uncertain. The procedure consists of searching for one or more possible hypothetical causal explanations of the text, these explanations containing, among other things, the semantic intention of the author, his subjective reasons for this meaning and for the writing down of the text, but …Read more

    Automated Argument Analysis – Comment on: Mizrahi & Dickinson: "Argumentation in Philosophical Practice: An Empirical Study"
    Evidence, Persuasion and Diversity. Proceedings of Ontario Society for the Study of Argumentation Conference, Vol. 12 (2020). 2020.
    The paper critically discusses an empirical study by Mizrahi & Dickinson 2020, which analyzes in a huge data base (JSTORE) the incidence of three types of philosophical arguments. Their results are: 1. Deductive arguments were the most commeon type of argument in philosophy until the end of the 20th century. 2. Around 2008 a shift in methodology occurred, such that the indcutive arguments outweigh other types of argument. The paper, first, criticizes the empirical study as grossly false and cons…Read more

    A Theory of Philosophical Arguments
    Evidence, Persuasion and Diversity. Proceedings of Ontario Society for the Study of Argumentation Conference, Vol. 12 (2020). 2020.
    In this article, a new, idealizing-hermeneutic methodological approach to developing a theory of philosophical arguments is presented and carried out. The basis for this is a theory of ideal philosophical theory types developed from the analysis of historical examples. According to this theory, the following ideal types of theory exist in philosophy: 1. descriptive-nomological, 2. idealizing-hermeneutic, 3. technical-constructive, 4. ontic-practical. These types of theories are characterized in …Read more

    Arguments from Expert Opinion – An Epistemological Approach
    In Catarina Dutilh Novaes, Henrike Jansen, Jan Albert Van Laar & Bart Verheij (eds.), Reason to Dissent. Proceedings of the 3rd European Conference on Argumentation, College Publications. pp. 403-422. 2020.
    In times of populist mistrust towards experts, it is important and the aim of the paper to ascertain the rationality of arguments from expert opinion and to reconstruct their rational foundations as well as to determine their limits. The foundational approach chosen is probabilistic. However, there are at least three correct probabilistic reconstructions of such argumentations: statistical inferences, Bayesian updating, and interpretive arguments. To solve this competition problem, the paper pro…Read more

    José Ángel Gascón’s essay "Where are dissent and reasons in epistemic justification?" is an exposition of a version of a social functionalist epistemology. I agree with Gascón's emphasis on reasons and on taking into account dissent as important parts of epistemology. But I think that these concerns do not require a social functionalist epistemology, but that, on the contrary, Gascón's social functionalist epistemology throws the baby out with the bathwater. It does so by excluding also a tradit…Read more

    Automatic actions: Agency, intentionality, and responsibility
    Philosophical Psychology 30 (5): 616-644. 2017.
    This article discusses a challenge to the traditional intentional-causalist conceptions of action and intentionality as well as to our everyday and legal conceptions of responsibility, namely the psychological discovery that the greatest part of our alleged actions are performed automatically, that is unconsciously and without a proximal intention causing and sustaining them. The main part of the article scrutinizes several mechanisms of automatic behavior, how they work, and whether the resulti…Read more

    Probabilistic Arguments in the Epistemological Approach to Argumentation
    In Frans H. Van Eemeren, Bart Garssen, David Godden & Gordon Mitchell (eds.), Proceedings of the 7th Conference of the International Society for the Study of Argumentation, Rozenberg; Sic Sat. pp. 1141-1154. 2011.
    The aim of the paper is to develop general criteria of argumentative validity and adequacy for probabilistic arguments on the basis of the epistemological approach to argumentation. In this approach, as in most other approaches to argumentation, proabilistic arguments have been neglected somewhat. Nonetheless, criteria for several special types of probabilistic arguments have been developed, in particular by Richard Feldman and Christoph Lumer. In the first part (sects. 2-5) the epistemological …Read more

    Das spezifische Ziel von Argumentationen ist nicht einfach, den Adressaten etwas glauben zu machen - dies wäre bloße Rhetorik ﷓, sondern: den Adressaten beim Erkennen der Akzeptabilität (insbesondere der Wahrheit) der These anzuleiten und ihn so zu begründetem Glauben, zu Erkenntnis zu führen. Argumentationen leiten das Erkennen an, indem sie in ihren Argumenten hinreichende Akzeptabilitätsbedingungen der These als erfüllt beurteilen und so den Adressaten implizit auffordern, diese Bedingungen z…Read more

    The article, first, reconstructs and criticizes Sandro Nannini’s incompatibilistic concept of freedom of decision and, second, develops a compatibilistic alternative, a synthesis of a rationalistic and an autonomous approach. Nannini justifies his conception primarily from a naturalistic point of view: it reflects our sense of agency, so he says. This is criticized as empirically wrong and methodically mistaken: The theory of freedom of decision is, actually, normative; it is about good decision…Read more

    The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authe…Read more

    “Dalla filosofia dell’azione alla filosofia della mente” è stato il percorso di alcuni filosofi di nazionalità varia degli anni 1980 – come Paul Churchland negli Stati Uniti o Ansgar Beckermann in Germania – che prima si sono interessati agli aspetti più teorici nella filosofia dell’azione, come il modo di funzionamento delle azioni e la loro spiegazione scientifica, e che poi, con l’arrivo e la diffusione dei personal computers e delle scienze cognitive, hanno ampliato e approfondito questo int…Read more
