    An Ontology of Intensional Entities

    The semantical framework is fundamentally intensional: neither possible worlds nor sets as basic entities, but rather, besides individuals, propositions, properties and relations (in intension). Logical truth is defined in terms of logical form (without mentioning this notion) without employing sets of models and the concept of truth in a model. Truth itself is explicitly defined (without recursion); the truth-conditions for the logical constants of the object-language become theorems derivable …Read more

    The Theory of Ontic Modalities
    Ontos Verlag. 2006.
    This book presents a comprehensive, non-model-theoretic theory of ontic necessity and possibility within a formal (and formalised) ontology consisting of states of affairs, properties, and individuals.

    Three indications for the existence of God in causal metaphysics
    International Journal for Philosophy of Religion 66 (1). 2009.
    With the emergence of modern physics a conflict became apparent between the Principle of Sufficient Cause and the Principle of Physical Causal Closure. Though these principles are not logically incompatible, they could no longer be considered to be both true; one of them had to be false. The present paper makes use of this seldom noticed conflict to argue on the basis of considerations of comparative rationality for the truth of causal statements that have at least some degree of philosophico-th…Read more
  • Husserls Dualismus
    History of Philosophy & Logical Analysis 10. 2007.
    The paper expounds the sense in which Husserl was not a psychophysical dualist – but also the sense in which he was a psychophysical dualist after all. On the one hand, it takes into account Husserl’s critical statements regarding “dualism,” on the other hand it closely considers Husserl’s understanding of the intentionality of phenomenal experiences. It is shown that Husserl’s writings contain several argumentations that can be interpreted as arguments for psychophysical dualism. It is argued t…Read more

    Actual existence, identity and ontological priority
    Erkenntnis 48 (2-3): 209-226. 1998.
    The paper first distinguishes ontological priority from epistemological priority and unilateral ontic dependence. Then explications of ontological priority are offered in terms of the reducibility of the actual existence or identity of entities in one ontological category to the actual existence or identity of entities in another. These explications lead to incompatible orders of ontological priority for individuals, properties of individuals and states of affairs. Common to those orders is, how…Read more

    Parmenides und die Logik der Existenz
    Grazer Philosophische Studien 47 (1): 59-75. 1994.
    Es wird gezeigt, daß sich Parmenides' Argument gegen Veränderung und Vielheit aus den Fragmenten seines Lehrgedichts so rekonstruieren läßt, daß es entweder formal korrekt wird, oder aber seine Prämisse,,Seiendes ist, Nichtseiendes ist nicht" evidentermaßen richtig ist. Beides zugleich ist nicht zu haben. Es wird plausibel gemacht, daß die Rekonstruktionen in Parmenides' Sinn sind. Betrachtet man sein Argument als formal korrekt, so stellt es, wenn wir das Zeugnis der Erfahrung akzeptieren, eine…Read more
  • Eine Explikation Des Begriffs Der Zurechnung
    Jahrbuch für Recht Und Ethik 2. 1994.
    This article provides an explication of the concept "imputation". On the one hand, this explication takes account of the common meaning of the concept and its generally intended range of application. On the other hand, it also provides a definition of the meaning of "y is to be imputed to x", which is precise and fruitful . The adequacy of this definition of "imputation" is justified in detail, in the light of the standards for explications. Since the concept "imputation" is a highly complex not…Read more

    Ontologically Minimal Logical Semantics
    Notre Dame Journal of Formal Logic 36 (2): 279-298. 1995.
    Ontologically minimal truth law semantics are provided for various branches of formal logic (classical propositional logic, S5 modal propositional logic, intuitionistic propositional logic, classical elementary predicate logic, free logic, and elementary arithmetic). For all of them logical validity/truth is defined in an ontologically minimal way, that is, not via truth value assignments or interpretations. Semantical soundness and completeness are proved (in an ontologically minimal way) for a…Read more

    Der cartesische DuaUsmus besteht nicht in der Behauptung, daß die Person und ihr Körper voneinander verschieden sind, sondern in der stärkeren Behauptung, daß sie beide ohne den anderen existieren können. Können ist dabei in einem außerordentlich schwachen Sinn zu nehmen, nämlich im Sinne der analytischen Möglichkeit. Descartes' Argument für diese Behauptung in der 6. Meditation ist im Rahmen der modal-epistemischen Logik als logisch korrektes Argument präzisierbar; daneben auch sein mit dem ers…Read more

    Classical intentionality
    Erkenntnis 65 (1): 25-45. 2006.
    In the first part, the paper describes in detail the classical conception of intentionality which was expounded in its most sophisticated form by Edmund Husserl. This conception is today largely eclipsed in the philosophy of mind by the functionalist and by the representationalist account of intentionality, the former adopted by Daniel Dennett and David Chalmers, the latter by John Searle and Fred Dretske. The very considerable differences between the classical and the modern conceptions are poi…Read more

    An onto-nomological theory of modality
    Poznan Studies in the Philosophy of the Sciences and the Humanities 91 (1): 47-72. 2006.
    This paper is dedicated to the formulation of a restricted theory of ontic modality (for example, I do not address questions that arise when modal operators interact with quantifiers, although some of the theoretical developments presented here certainly suggest such questions). As will be seen, notwithstanding its restrictions, the theory has a pleasing richness to it, as well as formal rigor and intuitive satisfactoriness. It also offers an unusual perspective on modality.
