Abstract

Jan Łukasiewicz was one of leading logicians of the XX-th century, universally regarded as the father of many-valued logics which proved to be the language for many paradigms of Computer Science and Artificial Intelligence, inventor of the Polish notation whose dual, the Reverse Polish notation has become implemented in computers and calculators, renowned historian of logic especially of logics of Stoics school and of Aristotle, twice the Rector of Warsaw University in academic years 1922/23 and 1931/32, Minister of Religious Beliefs and Public Enlightenment in the Paderewski cabinet in 1919, earlier in Ministry of Education in provisional Jan Kanty Steczkowski cabinet in 1918, born in Lwów at the time of autonomization of Galicia, student at the Lwów University at the time of its start toward flourishing, in Warsaw between 1915 and 1944, then an exile in Germany, Belgium and finally in Ireland, far from dear Lwów and Poland. He was one of pillars of the world famous Warsaw School of Logic alongside of Warsaw School od Mathematics, Lwów School of Mathematics, Warsaw - Lwów School of Philosophy together with Kazimierz Twardowski, Alfred Tarski, Stanisław Leśniewski, Stefan Banach, Hugo Steinhaus, Juliusz Schauder, Stanisław Mazur, Stanisław Ulam, Wacław Sierpiński, Kazimierz Kuratowski, Stefan Mazurkiewicz, Adolf Lindenbaum, Mordechaj Wajsberg, Bolesław Sobociński and many others. They worked in often difficult conditions, living through two world wars, regional conflicts, many of them lost all their possessions and archives, forced to rebuild their lives anew, often overseas, but always devoted to Poland and its causes

This work is based on the lecture delivered by the author at the 1st Warmian-Masurian Mathematics and Computer Science Colloquium at the Department of Mathematics and Informatics of the University of Warmia and Mazury in Olsztyn in May 2018 which commemorated centenaries of the announcement of many-valued logics by Łukasiewicz and of Poland’s independence. Author thanks Professors Andrzej Skowron and Jan Bazan who took part in the Colloquium and presented lectures on rough set theory.
