Symposium in honor of Kazimierz Ajdukiewicz (1890-1963)

Ajdukiewicz was one of the greatest philosophers and logicians of the 20th century, famous among others, for his categorial grammar, directive conception of meaning, and radical conventionalism. As a student of Kazimierz Twardowski and Jan Łukasiewicz, Ajdukiewicz belonged to the famous Lvov-Warsaw School, whose general methodological attitude he called "anti-irrationalism". Ajdukiewicz was a pioneer in applying logical tools to investigate philosophical problems. He is the author of three logic textbooks, including posthumously published "Pragmatic Logic", which he considered his "opus magnum". As a professor of philosophy and logic successively in Warsaw, Lwów, Poznań, and again in Warsaw he educated dozens of outstanding students and thus influenced significantly logical education in Poland. He also provided the impulse and gave directions to logical research in Polish logic and methodology of sciences.

The aim of the symposium "Logic, Language, and Cognition" is to recall the life and work of Kazimierz Ajdukiewicz, to discuss his heritage and newest developments of his ideas.

The symposium will take part on January 12 (afternoon session) and January 13, 2024, in a hybrid form: at the Faculty of Philosophy, University of Warsaw, room of Kazimierz Ajdukiewicz (109) and online.
