45Methodologische 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

91The Logic of Truth in Paraconsistent Internal RealismStudia Philosophica Estonica 1 (1): 76-83. 2008.The paper discusses which modal principles should hold for a truth operator answering to the truth theory of internal realism. It turns out that the logic of truth in internal realism is isomorphic to the modal system S4.

99Do 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

111Why 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

1931The 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

69In 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

30Coherence theories are regularly confronted with the objection that there can be many coherent systems, so that mere coherence is said to be insufficient as either the defining element of truth or even as a working criterion of truth. This objection has been called the “master objection”. If someone is taking coherence not only as a criterion supporting the truth of a theory, but as an ingredient to a definition of “true” she has to attack the master objection straight on

35Eine 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

107In 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

949Transcendental 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

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

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
