    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.

    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.

Za naczelną …Read more

When shall we say that A is irremovable or occurs in B essentially? We shall do it, if we can neither remove A from B nor replace A with A', not influencing upon important properties of B. On the other hand, when shall we say that the occurrence A in B is essential? We shall do …Read more

    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
