• 1. Die Psychologie vom empirischen Standpunkt (1874) Brentanos gilt als das Werk der Theorie der Intentionalität. Brentano macht dort die „intentionale Inexistenz” des Denkobjekts zum Definitionsmerkmal des Psychischen und zugleich zum zentralen Begriff eines einflußreichen Forschungsprogramms. Die Idee der intentionalen Beziehung, die in der Psychologie diese zentrale Stellung genießt, hat jedoch ganz bestimmte Aristotelisch-scholastische Wurzeln und wurde bereits in Brentanos Dissertation (186…Read more

    Brentanowska filozofia moralności
    Etyka 31 109-124. 1998.
    Brentano has divided mental phenomena into three main groups: presentations, judgements and emotions. Both judgements and emotions involve presentations as its foundation. Each judgement consists in acceptance or rejection of an object of some presentation; and each act of emotion consists in love or hate directed upon such presented object.

    Reinach’s Theory of Social Acts
    Studia Phaenomenologica 15 281-302. 2015.
    Some forty years before J.L. Austin, Adolf Reinach developed a highly articulated theory of speech acts. In this paper I present Reinach’s theory, and show some similarities and differences between his approach and the nowadays standard approaches, derived from Austin and Searle. Reinach’s work contains in fact all the cornerstones of the speech act theory. Still when comparing his theory with these contemporary approaches we can find at least two important differences. The first difference conc…Read more

    Ist das Gettier-Problem wirklich ein Problem?
    Conceptus: Zeitschrift Fur Philosophie 33 (82): 45-56. 2000.
    Viele Philosophen Glauben, daß die sogenannte „klassische” Definition des Wissens: (W)Das Subjekt S weiß, daß p =Df. (i) S glaubt (ist überzeugt), daß p; (ii) S hat eine Begründung (eine epistemische Rechtferigung) für seine Überzeugung, daß p; und (iii) es ist der Fall, daß p. durch das berühmte Gegenbeispiel Gettiers endgültig demoliert wurde: Gettier hat die folgende Situation konstruiert: (G)(1) Das Subjekt S hat eine gute induktive Begründung für die Überzeugung, daß p. (2) S hat die Überze…Read more
  • Die Theorie der Intersubjektivität bildet einen der zentralen Punkte des Husserlschen Systems. Im Rahmen der konsequenten Epistemisierung des Wahrheitsbegriffs, die Husserl von Brentano übernommen hat, wird die objektive Realität mittels des Begriffs der intersubjektiven epistemischen Begründung definiert. Die Konstitution der intersubjektiven Gemeinschaft bildet demgemäß die unentbehrliche Vorbedingung für die Konstitution der intersubjektiven Welt. Wir zeigen, daß die Husserlsche Theorie nicht…Read more

    Internal, External and Intra-Individual Relations
    Axiomathes 15 (4): 487-512. 2005.
    In this paper I argue that there are in fact external relations in Russell’s sense. The level at which we are forced to acknowledge them is, however, not the level of relations between concrete individual objects. All relations of this kind, which I will call “inter-individual” relations, can be construed as supervenient on the monadic properties of their terms. But if we pursue our ontological analysis a little bit deeper and consider the internal structure of a concrete individual, then we wil…Read more

    Content, rationality and mental causation
    Axiomathes 14 (4): 307-340. 2004.
    In this paper I will address the question of rationalizing mental causation which is involved in the processes of epistemic justification. The main problem concerning mental causation consists in the apparent incompatibility of the three following claims: (i) the subject's mental states (in particular his belief states) are realized by neural states of the subject's brain; (ii) the justifying character of belief transition consists in the fact that there are certain broadly logical relations bet…Read more

    Are Meanings in the Head? Ingarden’s Theory of Meaning
    Journal of the British Society for Phenomenology 30 (3): 306-326. 1999.
    The title question should be construed as an epistemological and not ontological one. Omitting the difficult problems of the ontology of intentionality we will ask, if all, what is needed to explain the phenomenon of meaningful use of words, could be found “in our private head” interpreted as a sphere of specific privileged access, the sphere that is in the relevant epistemological sense subjective, private or non public. There are many “mentalistic” theories of meaning that force us to the answ…Read more

    Quine claimed that to be is is to be a value of a bound variable. In the paper we assume that this claim contains an important philosophical insight and investigate its background. It is argued that there are two dimensions involved in Quine’s slogan: (i) the distinction between existing and non-existing objects and (ii) the question of the systematic ambiguity of being that can be traced back to Aristotle. At the first sight it is tempting to construe Quine’s criterion according to the first di…Read more
