176Methodologische überlegungen zu tierischen überzeugungenJournal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 38 (2): 347-355. 2007.A theory of the beliefs of non-human animals is not closed to us, only because we do not have beliefs of their kind. 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

161Why and how to be a DialetheistStudia Philosophica Estonica 1 (2): 208-227. 2008.In the first part the paper rehearses the main arguments why to be a dialetheist (i.e. why to assume that some contradictions are true). Dialetheism, however, has been criticised as irrational or self-refutating. Therefore the second part of the paper outlines one way to make dialetheism rational assertable. True contradictions turn out to be both believable and assertable. The argument proceeds by setting out basic principles of assertion and denial, and employing bivalent truth value operators…Read more

92Ist die transzendentalpragmatik letztbegründet oder holistisch?Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 26 (1): 153-168. 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

112In the last twenty years analytic philosophy has seen a rising interest in the philosophy of religion in general and in rational reconstructions of religion related arguments and Christian doctrines. In this short note I like to point to a problem that although cosmological arguments play a great role in the present discussion has not received the attention, I believe, it deserves.[1] An old objection to cosmological arguments, named “the Carriage Objection” by Schopenhauer[2], charges them as b…Read more

164Die 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

3471The following essay reconsiders the ontological and logical issues around Frege’s Basic Law (V). If focuses less on Russell’s Paradox, as most treatments of Frege’s Grundgesetze der Arithmetik (GGA)1 do, but rather on the relation between Frege’s Basic Law (V) and Cantor’s Theorem (CT). So for the most part the inconsistency of Naïve Comprehension (in the context of standard Second Order Logic) will not concern us, but rather the ontological issues central to the conflict between (BLV) and (CT).…Read more

2094Transcendental Logic RedefinedReview of Contemporary Philosophy 7. 2008.Traditionally transcendental logic has been set apart from formal logic. Transcendental logic had to deal with the conditions of possibility of judgements, which were presupposed by formal logic. Defined as a purely philosophical enterprise transcendental logic was considered as being a priori delivering either analytic or even synthetic a priori results. In this paper it is argued that this separation from the (empirical) cognitive sciences should be given up. Transcendental logic should be und…Read more

67Naturalistic explanations (of linguistic behaviour) have to answer two questions: What is meant by giving a naturalistic explanation, and what does it explain after all? Two kinds of descriptivism present in Wittgenstein´s work are distinguished and applied to Hirsch´s “division problem”. They answer the two questions raised and keeping in mind their distinction is important to assess naturalistic explanations.

183In our dealings with animals at least most of us see them as conscious beings. On the other hand the employment of human categories to animals seems to be problematic. Reflecting on the details of human beliefs, for example, casts serious doubt on whether the cat is able to believe anything at all. These theses try to reflect on methodological issues when investigating animal minds. Developing a theory of animal mentality seems to be a test case of the interdisciplinary research programme in cog…Read more

166Internal RealismIn Patricia Hanna (ed.), An Anthology of Philosophical Studies, Atiner. 2006.This essay characterizes a version of internal realism. In §1 I will argue that for semantical reasons we should be realists of a strong kind. In §2 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 realism’ points to the justification aspect of truth. The ‘realism’ of ‘internal realism’ points to the cor…Read more

97Eine Notiz zu den Argumentationsstrukturen in der „Widerlegung des Idealismus”Kant Studien 92 (1): 13-18. 2001.Kant spricht bezüglich der Widerlegung des Idealismus von einem „Beweis”. Das ist sicher der höchste Status, den er bereit ist, einem Argument zuzuschreiben. Diese Notiz hier soll zeigen, daß Kant diesen Anspruch zu Recht erhebt. Dazu reicht eine an der sprachlichen Oberflächenstruktur orientierte Formalisierung. Nun hat Kant natürlich die moderne Prädikatenlogik nicht gekannt, aber für den Gebrauch dieser Logik und ein dem gemäßes Räsonieren bedarf es bekanntlich ja auch nicht der ausdrückliche…Read more

124Can contradictions be asserted?Logic and Logical Philosophy 7 (n/a): 167. 1999.In a universal logic containing naive semantics the semantic antinomies will be provable. Although being provable they are not assertiblebecause of some pragmatic constraints on assertion I will argue for. Furthermore, since it is not acceptable that the thesis of dialethism is a dialethiaitself, what it would be according to naive semantics and the prefered logical systems of dialethism, a corresponding restriction on proof theory isnecessary.

218Do 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
