    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.

Questions direct scientific research, are used as research tools and are an important medium of transferring knowledge in teaching. The book is intended as a par excellence philosophical monograph of the theory of questions, presenting the most important erotetic problems, their general background and selected practic…Read more

    Poznan Studies in the Philosophy of the Sciences and the Humanities 99 129-169
    Before presenting the analysis of logical form of questions, I shall make some comments concerning questions in natural language. By utilizing examples of such questions I shall try to justify my conception of the semiotic function of questions and provide a basis for my analysis of their structure. One of the main aims of this chapter is to introduce definitions of erotetic concepts which I will use in the subsequent parts of the book and to sketch definitional connections between elements of t…Read more

The first function consists in indicating some objects; the second one consists in ascribi…Read more

    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

    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
