160Three indications for the existence of God in causal metaphysicsInternational 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 DualismusE-Journal Philosophie der Psychologie 9. 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 …Read more

31Eine logische Rekonstruktion der platonischen PrädikationstheorieGrazer Philosophische Studien 43 (1): 163-175. 1992.In diesem Aufsatz wird eine axiomatisierte logische Rekonstmktion der Platonischen Prädikationstheorie vorgeschlagen, aufbauend auf der Ähnlichkeitsrelation. Die Theorie ist konsistent und trivial. Selbst-Prädikation bereitet darin keine Schwierigkeiten und das Dritte-Mann-Argument wird als harmlos aufgezeigt. Es werden Kriterien dafür, daß etwas ein Standardgegenstand (eine Form oder Idee) ist, aufgestellt und ausgeführt, daß diese die Platonische Ideentheorie implizieren. Die Grenzen von Piato…Read more

10Parmenides und die Logik der ExistenzGrazer 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

74An alternative semantics for modal predicate-logicErkenntnis 37 (3). 1992.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

41The phenomenological approach to the philosophy of mind, as worked out by Husserl, has been severely criticized by philosophers within the Wittgensteinian tradition and, implicitly, by Wittgenstein himself. This book examines this criticism in detail, looking at the writings of Wittgenstein, Ryle, Hacker, Dennett, and others. In defending Husserl against his critics, it offers a comprehensive fresh view of phenomenology as a philosophy of mind.

31Ontologically Minimal Logical SemanticsNotre 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

186From Plato to Frege: Paradigms of Predication in the History of Ideas (review)Metaphysica 10 (2): 199-214. 2009.One of the perennial questions of philosophy concerns the simple statements which say that an object is so and so or that such and such objects are so and so related: simple predicative statements. Do such statements have an ontological basis, and if so, what is that basis? The answer to this question determinesâor in any case, is expressive ofâa specific fundamental outlook on the world. In the course of the history of Western philosophy, various philosophers have given various answers to t…Read more

642A Cosmo-Ontological Argument for the Existence of a First Cause - Perhaps GodEuropean Journal for Philosophy of Religion 4 (2): 169--178. 2012.The paper presents a new version of the "Cosmological Argument" – considered to be an ontological argument, since it exclusively uses ontological concepts and principles. It employs famous results of modern physics, and distinguishes between event-causation and agent-causation. Due to these features, the argument manages to avoid the objection of infinite regress. It remains true, however, that the conclusion of the argument is too unspecific to be unambiguously considered an argument for the ex…Read more

51Events and their realityLogic and Logical Philosophy 2 (5): 23-33. 1994.This paper presents a set-theoretical conceptual framework for theorizing about (possible) events , and states some analytical and synthetical principles which describe the way in which the concept of reality (or actuality ) applies to them. The conceptual framework has few primitives, but is nevertheless of great definitional power; the demonstration of this will fill the first part of the paper

29Descartes' Argument für den psycho-physischen Dualismus im Lichte der modal-epistemischen LogikGrazer Philosophische Studien 35 (1): 83-101. 1989.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

15This book is intended as a comprehensive defense of psycho-physical dualism. It gives answers to the question of what dualism may consist in, and inquires into the broadly cultural motivation behind accepting dualism or its opponent physicalism. Arguments for dualism, among them strengthened versions of the famous classical arguments, are presented and defended against objections. Moreover, the various general objections to dualism are criticized in detail, for example, the allegation that duali…Read more
