63The 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

121The 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.

98This 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.

5How 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

23An 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

132Restall and Beall on Logical Pluralism: A CritiqueErkenntnis 79 (S2): 293-299. 2014.With their book Logical Pluralism, Jc Beall and Greg Restall have elaborated on their previous statements on logical pluralism. Their view of logical pluralism is centred on ways of understanding logical consequence. The essay tries to come to grips with their doctrine of logical pluralism by highlighting some points that might be made clearer, and questioning the force of some of Beall’s and Restall’s central arguments. In that connection seven problems for their approach are put forth: (1) The…Read more

68Conceptual atomism of this type is incompatible with many other semantic approaches. One of these approaches is justificationist semantics. This book assumes conceptual atomism.
-
60In this talk I consider two problems for conceptual atomism. Conceptual atomism can be defended against the criticism that it seems to contend that all concepts are simply innate (even technical concepts to pre-technological humanoids) by specifying the innateness thesis as one of mechanisms of hooking up mental representations (concepts as language of thought types) to properties in the world (§1). This theory faces a problem with non-referring expressions/concepts, it seems. Conceptual atomism…Read more

127Lessons from Sartre for the Analytic Philosophy of MindAnalecta Husserliana 88 63-85. 2005.There are positive and negative lessons from Sartre: - Taking up some of his ideas one may arrive at a better model of consciousness in the analytic philosophy of mind; representing some of his ideas within the language and the models of a functionalist theory of mind makes them more accessible and inte¬grates them into the wider picture. - Sartre, as any philosopher, errs at some points, I believe; but these errors may be instruc¬tive, especially in as much as they mirror some errors in some c…Read more

109Truth In Internal RealismIn Julian Nida-Rümelin (ed.), Rationality, Realism and Revision, . 1999.This essay deals with the concept of truth in the context of a version of internal realism . In §1 I define some variants of realism using a set of realistic axioms. In §2 I will argue that for semantical reasons we should be realists of some kind. In §3 I plead for an internalistic setting of realism starting from the thesis that truth is, at least, not a non-epistemic concept. We have to bear the consequences of this in form of a more complicated concept of truth. The "internal" of "internal r…Read more

39Ist die transzendentalpragmatik letztbegründet oder holistisch?Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 26 (1). 1995.Is transcendental pragmatics a matter of ultimate foundation or a matter of holism? Transcendental pragmatics as developed by Karl-Otto Apel has been the object of various criticisms. Against the fallibilists' claim (Albert) that argumentation is at last either dogmatic, axiomatic or circular, the transcendental pragmatists have given an argument that ultimate foundation ('Letztbegründung') cannot be proved to be impossible. But this clarification of their claims leaves open the questions whethe…Read more

93Do Cats Have Beliefs?In Stephen Hales (ed.), What Philosophy Teaches You about Your Cat, . 2008.In our dealings with our pets, and larger animals in general, at least most of us see them as conscious beings. We say “the cat feels pain” ascribing sensation. We notice “My cat wants to get in the kitchen because she thinks there is some cheese left” ascribing beliefs and desires. Explanations likes these can be employed on a variety of occasions, and usually we are content with what they say. We seem to understand why our cat is doing what she does. On the other hand the employment of human c…Read more
