166The paper argues against a commitment to metaphysical necessity, semantic modalities are enough. The best approaches to elucidate the semantic modalities are (still) versions of lingustic ersatzism and fictionalism, even if only developed in parts. Within these necessary properties and the difference between natural and semantic laws can be accounted for. The proper background theory for this is an updated version of Logical Empiricism, which is congenial to recent trends in Structural Realism. …Read more

196The following considerations concern modelling Belief Dynamics (BD) not just in the sense of a formalization, but rather in the sense of building a computational model and implementing the corresponding data structures and algorithms of recomputing beliefs. The purpose of such a project is to illustrate some ideas about belief changes in a Web of Beliefs (WoB) to explore and deepen one's understanding of belief changes by trying to implement or improve corresponding algorithms.

137This essay tries to elucidate structural elements of consciousness by drawing on phenomenological descriptions of consciousness and employing representationalist models of consciousness. The aim is not to explain the genesis of self-awareness, but to outline different aspects of its structure.

7How Are Semantic Metarepresentations Built and Processed?Kriterion - Journal of Philosophy 1 (26): 22-38. 2012.This paper looks at some aspects of semantic metarepresentation. It is mostly concerned with questions more formal, concerning the representation format in semantic metarepresentations, and the way they are processed. Section 1 distinguishes between metacognition and metarepresen- tation in a narrow and broad sense. Section 2 reminds the reader of some main areas where metarepresentations have to be used. The main part considers the ways that metarepresentations are built and processed. Section …Read more

27An introduction to paraconsistent logicsPeter Lang. 2005.This book gives an overview of paraconsistent logics - that is logics which allow for inconsistency. Although allowing for inconsistency, paraconsistent logics are worth considering: Logical systems are worth considering in their own right since we can learn about very abstract structural properties of logics and the concepts employed within them such as negation, necessity and consistency. Some non-classical logics are especially of interest from a philosophical perspective since they alone off…Read more

19Die Welt ist die Gesamtheit der Tatsachen, nicht der DingeGrazer Philosophische Studien 57 (1): 111-131. 1999.Die in Wittgensteins Anfangsthesen des Tractatus formulierte Ansicht, daß Tatsachen die Bausteine der Welt ausmachen, kann auch so interpretiert werden, daß Tatsachen physische Entitäten sind. Die These von der physischen Existenz von Tatsachen wird in der analytischen Philosophie jedoch weitgehend abgelehnt. Hier wird hingegen versucht, diese Position als Tatsachen-Ontologie kohärent zu entwickeln. Vorzüge diese Position wären u.a. eine elegante Deutung der Vielheit verschiedener wahrer Aussage…Read more

Starting from a theory of human beliefs and working on a building block model of propositional attitudes a theory of animal beliefs is viable. Such a theory is an example of the broader conception of a heterophenomenological approach to animal cognition. The theory aims at outlining the crucial differences between human and animal beliefs as well as the relations between these att…Read more

101Do logical truths carry information?Minds and Machines 13 (4): 567-575. 2003.The paper deals with the question whether logical truth carry information. On the one hand it seems that we gain new information by drawing inferences or arriving at some theorems. On the other hand the formal accounts of information and information content which are most widely known today say that logical truth carry no information at all. The latter is shown by considering these accounts. Then several ways to deal with the dilemma are distinguished, especially syntactic and ontological soluti…Read more
