  1. Aristoteles: Analytica Priora. Buch I. Übersetzt Und Erläutert.Theodor Ebert & Ulrich Nortmann (eds.) - 2007 - Akademie Verlag.
    This is a German translation with commentary of Aristotle’s Prior Analytics, Book I. The introduction (‚Einleitung‘, pp. 97–182) contains a concise history of the reception of Aristotle’s syllogistic from Theophrastus to Kant and Hegel. The commentary places special attention to the modal chapters (i. e. I 3 and 8–22). Aristotle’s modal syllogistic is treated with more sympathy than in other modern commentaries and discussions of this part of Aristotle’s logic.

    The Logic of Necessity in Aristotle--An Outline of Approaches to the Modal Syllogistic, Together with a General Account of de Dicto - and de Re -Necessity.Ulrich Nortmann - 2002 - History and Philosophy of Logic 23 (4):253-265.
    This article investigates the prospect of giving de dicto- and de re-necessity a uniform treatment. The historical starting point is a puzzle raised by Aristotle's claim, advanced in one of the modal chapters of his Prior Analytics, that universally privative apodeictic premises simply convert. As regards the Prior and the Posterior Analytics, the data suggest a representation of propositions of the type in question by doubly modally qualified formulae of modal predicate logic that display a necessity operator in two distinct (...)

    Warum Man Essentialist Sein Kann – Eine Logische Konstruktion Im Schnittfeld Von Sprache, Ontologie Und Naturwissenschaft.Ulrich Nortmann - 2002 - Erkenntnis 57 (1):1-39.
    Essentialism is, on the one hand, anchored with considerable firmness in a common sense picture of the world. On the other hand, it was dismissed for logico-philosophical reasons by a scientifically minded theorist like Quine. ``New essentialists'' like Kripke did engage in very profitable theorizing on an essentialist basis, but made no significant effort to investigate the prospects of imparting to an essentialist metaphysics a solid foundation within a scientific world view. These foundational prospects are the concern of the article. (...)

  6. Building on Frege: New Essays About Sense, Content and Concepts.Albert Newen, Ulrich Nortmann & Ranier Stuhlmann-Laeisz - 2001 - Center for the Study of Language and Inf.
    An outstanding philosopher-logician, Gottlob Frege's work has received much attention in recent years. In the pursuit of Frege's main goal to solidify the foundations of mathematics and scientific work, Frege conceived a comprehensive philosophy of language and developed the main thesis of logicism, that mathematics is reducible to logic. This book contains essays covering a large range of issues related to Frege that will be of great interest to philosophers working on these issues. This volume represents an important addition to (...)

    How to Extend the Dialogical Approach to Provability Logic.Ulrich Nortmann - 2001 - Synthese 127 (1-2):95 - 103.
    The core ideas of the dialogicalapproach to modal propositional logic are explainedby means of an elementary example. Subsequently,ways of extending this approach to the system G ofso-called provability logic are checked, therebyraising the question whether the dialogician is inneed of shaping his Nichtverzögerungsregel(non-delay-rule), in order to get it sufficiently precise,in different ways for different modal systems.

    Against Appearances True: On a Controversial Modal Theorem in Metaphysics Theta 4. [REVIEW]Ulrich Nortmann - 2006 - Zeitschrift für Philosophische Forschung 60 (3):380-393.
    Aristotle asserts in Met. Theta 4 that „if A, then B“ is a consequence of „if A is possible, then B is possible,“ for any sentences A and B. His assertion has often been questioned, or even been suspected to be a crude mistake. After a discussion of a typical objection, it is shown that a plausible reading of Aristotle’s claim is true: The twice occurring „if – then“ has to be understood in the sense of logical entailment, and sentences (...)

    The core ideas of the dialogical approach to modal propositional logic are explained by means of an elementary example. Subsequently, ways of extending this approach to the system G of so-called provability logic are checked, thereby raising the question whether the dialogician is in need of shaping his "Nichtverzögerungsregel", in order to get it sufficiently precise, in different ways for different modal systems.

    Vier Philosophen Über Semantische Paradoxien.Ulrich Nortmann - 1995 - History and Philosophy of Logic 16 (2):217-244.
    In his treatise on sophisms, the medieval logician and philosopher J. Buridan expounded a theory on what we have come to call semantic paradoxes. His theory has not yet been fully understood. The present paper aims at showing that Barwise's and Etchemendy's considerations on paradoxes (founded upon Aczel's non-well-founded sets) provide the framework for an improved understanding. Barwise's and Etchemendy's account is contrasted with Kripke's. Finally, a recent analysis of Buridan's position by Epstein is criticized.

  23. Der Platonismus, wissenschaftstheoretisch betrachtet.Ulrich Nortmann - 1998 - Logical Analysis and History of Philosophy 1.
    Concepts from the philosophy of science such as the concepts of theoreticity and empirical content have been initially applied primarily in the field of scientific theories. In the following paper, while focussing on several exemplary cases, I shall investigate whether or not such categories can also be meaningfully applied to philosophical theories. Plato's metaphysics of forms stands in the foreground, and, for this philosophical theory, such an application appears to be meaningful. Having established this, we may further explore the question (...)

  25. Platon über Gegenstände und Methode der Mathematik.Ulrich Nortmann - 2006 - Logical Analysis and History of Philosophy 9.
    It is argued that Plato views forms as the proper objects of mathematical research, in contrast to what Aristotle says about the ontologically intermediate state of math?matiká in Platonism. Plato’s particularistic conception of ideas is compared with the nowadays customary mathematical practice of studying types of structures by examining canonical representatives. The case is illustrated by considering the shift from a universalistic conception of natural numbers, in the Frege-Russell-tradition, to a particularistic conception, as in von Neumann. Finally, the characterization of (...)
