    Scrutiny of Ajdukiewicz’s concepts of definition
    with Jacek Jadacki
    Studies in East European Thought 68 (1): 11-20. 2016.
    The paper provides an analysis of two traditionally accepted distinctions between nominal and real definitions. The historical background is Kazimierz Ajdukiewicz’s conceptions of definitions as well as remarks by other members of the Lvov-Warsaw School of philosophy. The aim of the paper is to show that the analysed distinction, at least in Ajdukiewicz’s version, cannot be sustained.

    The main subject of the paper is to present the criteria which help us to establish whether a given ontological controversy (or even a whole dispute) is substantial or merely verbal. Metaphysics is often perceived as a discipline composed of endless disputes with no glimpse of hope for solution. This fact makes many philosophers claim that ontology is nothing more than matter of linguistic choice. In this paper, we argue that there exist certain methodological tools which enable us to establish …Read more

    Intuicje modalne
    with Jacek J. Jadacki
    Roczniki Filozoficzne 56 (1): 39-59. 2008.
    The authors proposes a philosophical hinterland of nomological type for various conceptions of alethic modalities. Differences among these conceptions are explained by the fact, that moda­lizators can be relativized to various types of laws. Thus one can speak respectively about logic and definitional, ontical and physical, technical and dispositional, psychological and methodo­logical, and finally deontic modalities. The authors shows that in their conceptual appa­ratus modal logics find intuit…Read more

    Bocheński on authority
    Studies in East European Thought 65 (1-2): 115-133. 2013.
    Józef Maria Bocheński introduced an important distinction between deontic and epistemic authority. A typical example of epistemic authority is the relation of a teacher to his students; a typical example of deontic authority is the relation between an employer and his employee. The difference between the two lies in domains of authority: declarative sentences make up the domain in the case of epistemic authority, orders—in the domain of deontic authority. In the article, I analyze in detail the …Read more

    Performatives and Imperatives
    European Journal of Analytic Philosophy 7 (2): 17-34. 2011.
    The term “performative” is used in at least two different senses. In the first sense, performatives are generatives, i.e. expressions by the use of which one creates new deontic states of affairs on the ground of extralinguistic conventions. In the second sense, performatives are operatives, i.e. expressions which contain verbal predicates and state their own utterances. In the article, both these types of expressions are compared to the class of imperatives which are characterized as expressio…Read more
  • Chapter XI. The Analysis of Erotetic Situation
    Poznan Studies in the Philosophy of the Sciences and the Humanities 99 241-259
    In this chapter, I sketch the aspects of erotetic which, on the one hand, are not presented in previous chapters, and, on the other hand, are important with respect to some practical applications of erotetics which are presented in the third part of the book. I start from describing the modifications of a typical erotetic situation and indicating some kinds of questions put in untypical situations. Furthermore, I shall concentrate on the situational concepts of an answer. The last part of the ch…Read more

    Minimalizm etyczny Tadeusza Kotarbińskiego
    with Jacek Jadacki
    Etyka 39 48-71. 2006.
    Artykuł zawiera zarys rekonstrukcji poglądów etycznych Tadeusza Kotarbińskiego. Analiza pism etycznych Kotarbińskiego — niestety dalekich od ideału precyzji — pozwala sądzić, że na jego system etyczny składają się m.in. następujące tezy. Podstawową negatywną normą moralną jest norma „Nie powinieneś nikomu czynić zła ponad niezbędną potrzebę”, a podstawową pozytywną normą moralną jest norma „Powinieneś komuś czynić dobro”; stąd etykę Kotarbińskiego wolno nazwać „altruizmem lokalnym”. Za naczelną …Read more
