• 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.

    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

    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

    Maria Kokoszyńska: Between the Lvov-Warsaw School and the Vienna Circle
    Journal for the History of Analytical Philosophy 5 (2). 2017.
    Maria Kokoszyńska-Lutmanowa was one of the most outstanding female representatives of the Lvov-Warsaw School.

She was also influenced by Alfred Tarski whose results in semantics she analyzed and popularized. After World War II, she got the chair of logic in University of Wrocław and she organized studies in logic in this academic center. In the 1930s, Kokoszyńska kept in con…Read more

  • Let us assume that the expression A is a segment of the expression B. Now, let us assume that we try to transform the expression B into the expression B', removing A from B or replacing A with another expression, say A'. 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
  • The article contains the results of the analysis of concepts connected with semantic functions of names. The conception of Jacek Jadacki, exposed in his "Spór o granice jezyka" ("Controversy on the limits of language"), is the point of departure of this analysis. The following theses are formulated and argued for. (1) There are two basic semantic functions of names: the referential and the descriptive one. The first function consists in indicating some objects; the second one consists in ascribi…Read more
