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 pointed out, and it is argued that the classical conception is more satisfactory than the two modern ones, not only regarding phenomenal adequacy, but also on the grounds of epistemological considerations. In the second part, the paper argues that classical intentionality is not naturalizable, that is, physicalizable. Since classical intentionality exists (in the experiences that display it), the non-naturalizability of classical intentionality implies psychophysical dualism.

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 from the axioms for "to intend"--the basic semantical relation

The paper provides new perspectives for a dualistic conception of mental causation by putting causation that originates in a nonphysical self into an evolutionary perspective. Nonphysical causation of this type - free agency -, together with nonphysical consciousness, is regarded as being not only compatible with physics, but also as having a natural place in nature. It is described how free agency can work, on the basis of the brain, and how it can be compatible with the result of the Libet-experiment. The necessary condition for the existence of free agency is that the physical macro-world is indeterministic to a degree that is relevant for living beings, that is, for their survival and well-being. From an evolutionary point of view, and on the basis of the facts of consciousness, it is more likely than not that this condition is in fact fulfilled.

Uwe Meixners Essay stellt in gedrängter Form die Hauptgedanken seines 1997 publizierten großen systematischen Entwurfes “Ereignis und Substanz” vor, der neben einer Ontologie im engeren Sinn auch eine Bewusstseinstheorie, eine philosophische Gotteslehre und eine Theodizee beinhaltet. Im vorliegenden Beitrag erläutert er seinen Begriff von Substanz, der eng mit seiner Sicht von Kausalität zusammenhängt und vertritt dabei den radikalen Standpunkt, dass Ereigniskausalität auf Agenskausalität, die von transzendenten Substanzen als Realisationssubjekten getragen werde, reduziert werden könne. Dieser monadische Ansatz wird dann zu einem “eingeschränkten metaphysischen Pluralismus” weiterentwickelt, dessen zentrale These darin besteht, dass das Wirklichmachen – in Meixners Worten die “Realitätsmitteilung an die Welt” – bei einer einzigen Zentralsubstanz liege. Eine Idee, die vor allem aus der Perspektive der modernen japanischen und der chinesischen Philosophie auf Interesse gestoßen ist.

I argue (1) that it is not philosophically significant whether causation is linguistically represented by a predicate or by a sentence connective; (2) that there is no philosophically significant distinction between event- and states-of-affairs-causation; (3) that there is indeed a philosophically significant distinction between agent- and event-causation, and that event-causation must be regarded as an analog of agent-causation. Developing this point, I argue that event-causation's being in the image of agent-causation requires, mainly, (a) that the cause is temporally prior to the effect, (b) that the cause necessitates (is sufficient with necessity) for the effect. Causal necessity is explained as a derivative of nomological necessity, and finally, via a definition of the causal sentence connective, the logic of event-causation is shown to be a part of temporal modal logic.

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 calculus of classical elementary predicate logic

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-theological relevance and can be taken to indicate ( not prove) the existence of God. The paper’s comparatively modest aim is to establish belief in the existence of God as a rational metaphysical option, not as a rational obligation. In its final section, enriched causal considerations lead to an indication ( not proof) of God as that which guarantees the unified continuance of the physical world.

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 notion, its explication in turn involves an explication, an analysis, or at least a clarification of each of the many concepts that constitute it: event, event causality, agent , realization, action, agent causality, personhood, knowledge of what one is doing, etc. Competing interpretations of some of these concepts are considered and they are evaluated in comparison to the interpretation here preferred. To the extent possible, a justification is given for the use of the two concepts most central to imputation - causal necessity and realization - since they clearly cannot be understood as "empirical" concepts. The role freedom and volition play for imputation is also explained. Differentiations are drawn between imputation in a general and legal sense, between purely causal imputation and imputation in its full sense, between participatory and non-participatory imputation, and between simple imputation and imputation to a certain extent or degree. Dieser Aufsatz enthält eine Explikation des Zurechnungsbegriffes, d.h. eine einerseits die vorfindliche Bedeutung und die intendierte Anwendung respektierende, aber andererseits auch präzise , fruchtbare Bedeutungsneufestlegung für "y ist x zuzurechnen". Ihre Adäquatheit im Hinblick auf die eben angesprochenen Explikationesziele und - leitlinien wird ausführlich gerechtfertigt. Da es sich beim Zurechnungsbegriff um einen höchst komplexen Begriff handelt, involviert seine Explikation die Explikation, die Analyse oder wenigstens die Klarstellung jedes der vielen Begriffe, die in seine Konstitution eingehen: des Begriffes des Ereignisses, der Ereigniskausalität, des Agens, des Realmachens, der Handlung, der Agenskausalität, der Person, des Wissens um das, was man tut etc. Für einige dieser Begriffe gibt es konkurrierende Interpretationen, die gegen die favorisierte Interpretation abgewogen werden. Die zwei für Zurechnung zentralsten Begriffe - die der kausalen Notwendigkeit und der des Realmachens - erhalten - soweit wie möglich - eine Rechtfertigung ihres Gebrauchs, da sie sich gewiß nicht als "empirische" Begriffe auffassen lassen. Welche Rolle Freiheit und Willentlichkeit für Zurechnung spielen, wird abgeklärt. Es wird unterschieden zwischen rechtlicher und eigentlicher Zurechnung, rein kausaler Zurechnung und Zurechnung im vollen Sinn, partizipatorischer und nichtpartizipatorischer Zurechnung, außerdem zwischen einfacher Zurechnung und Zurechnung in einem gewissen Grade
