    A notation system for ordinal using ψ‐functions on inaccessible mahlo numbers.Helmut Pfeiffer & H. Pfeiffer - 1992 - Mathematical Logic Quarterly 38 (1):431-456.
    G. Jäger gave in Arch. Math. Logik Grundlagenforsch. 24 , 49-62, a recursive notation system on a basis of a hierarchy Iαß of α-inaccessible regular ordinals using collapsing functions following W. Buchholz in Ann. Pure Appl. Logic 32 , 195-207. Jäger's system stops, when ordinals α with Iα0 = α enter. This border is now overcome by introducing additional a hierarchy Jαß of weakly inaccessible Mahlo numbers, which is defined similarly to the Jäger hierarchy. An ordinal μ is called Mahlo, (...)

    Aristotle on the Cause of Unity: the Argument of Metaphysics H.3–6.Christian Pfeiffer - forthcoming - Phronesis:1-35.
    I argue that Metaphysics H.6 is not an isolated chapter but the conclusion of an argument begun in H.3. This view will provide further and better arguments for the following view about long-standing interpretative debates: first, Aristotle provides a substantive account of the unity of the composite substance (although he also briefly addresses the unity of the form); second, neither Aristotle’s conception of matter nor his account of form changes between H.1–5 and H.6; and third, H does not rely on (...)

    Ethics on the Job: Cases and Strategies.Raymond S. Pfeiffer & Ralph P. Forsberg - 1995 - Belmont, CA: Wadsworth Publishing Co.. Edited by Ralph P. Forsberg.
    ETHICS ON THE JOB guides the reader through a step-by-step analysis to help them make good decisions in the face of ethical conflict. With the RESOLVEDD strategy, the authors have devised a powerful system for ethical decision-making in the workplace, which they teach students to implement through timely case studies and detailed analyses. Students develop a working grasp of important philosophical principles and their application in ethical conflicts, and learn to apply the RESOLVEDD strategy to ethical issues in their own (...)

    Proofs and computations.Helmut Schwichtenberg - 2012 - New York: Cambridge University Press. Edited by S. S. Wainer.
    Driven by the question, 'What is the computational content of a (formal) proof?', this book studies fundamental interactions between proof theory and computability. It provides a unique self-contained text for advanced students and researchers in mathematical logic and computer science. Part I covers basic proof theory, computability and Gödel's theorems. Part II studies and classifies provable recursion in classical systems, from fragments of Peano arithmetic up to Π11-CA0. Ordinal analysis and the (Schwichtenberg-Wainer) subrecursive hierarchies play a central role and are (...)

    Snyder and Habermas on the war in Ukraine: a critical discourse analysis of elite media discourse in Germany.Helmut Gruber - forthcoming - Critical Discourse Studies.
    This article presents a critical qualitative study of two opinion articles, written by two eminent scholars (Jürgen Habermas and Timothy Snyder), on the German government’s hesitant arms supply for Ukraine during the first phase of the Russian war of aggression in 2022. The main aim of the article is the uncovering of the discursive practices of critique performed by two major public intellectuals. This case study thus allows insights into the simplistic representation of the Russo-Ukrainian war in German elite media (...)

    Comemos combustibles fósiles.Dale Allen Pfeiffer - 2006 - Polis 14.
    Las tasas de producción y consumo de alimentos en el mundo se hacen insostenibles. Estados Unidos está a la cabeza de los países que exceden con creces su capacidad en esta materia. La causa principal es la incorporación de combustibles fósiles en la producción de alimentos desde 1950, tanto en forma de energía cinética, como también en los pesticidas y otros productos utilizados en su producción. Según el autor, literalmente nos estamos comiendo los hidrocarburos rápidamente y sin tener ninguna alternativa (...)

    Zum systematischen Stand der FiktionstheorieReflections on the systematic state of the theory of fiction.K. Ludwig Pfeiffer - 1990 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 21 (1):135-156.
    The theory of fiction is systematically locatedbetween different types of discourse, of which philosophy, literary criticism and psychology/psychoanalysis are perhaps the most important. Mythesis is thatempiricist, mainly British philosophical approaches provide fascinatinghistorical models for an analysis of the situation in which we seem caught today between tendencies towards panfictionalization (since Vaihinger) and towards fairly rigid distinctions between fiction and reality. In my perspective, empiricist philosophy is not so much concerned with what isgiven, but with thecontrol of distinctions between the real (...)
