Institute of Philosophy, University of Warsaw

Institute of Philosophy of the University of Warsaw (Polish Instytut filozofii Uniwersytetu Warszawskiego) is a research institution located in Warsaw, part of the Faculty of Philosophy and Sociology of the University of Warsaw. It is renowned mainly for its contribution to the development of modern logic and analytic philosophy (Lvov-Warsaw School - Alfred Tarski, Jan Łukasiewicz, Kazimierz Ajdukiewicz, Tadeusz Kotarbiński, Stanisław Leśniewski) and to history of ideas (Warsaw School of the History of Ideas - Władysław Tatarkiewicz, Stanisław Ossowski, Maria Ossowska, Leszek Kołakowski, Adam Schaff). Provides master's degree studies, doctor's degree studies and postgraduate studies in philosophy both in Polish and in English.

The 18th and 19th century
The main centre of the medieval and early modern Polish philosophy was Kraków - history of philosophy in Warsaw begins in the 18th century. In the pre-partition Varsovian institutions, the Collegium Nobilium and the Szkoła Rycerska to the lecturers of philosophy belonged Antoni Wiśniewski and Marcin Nikuta. In the 19th century, after the foundation of the University of Warsaw in 1815, due to russification of the schools Polish philosophy, both idealist and positivist, developed mainly outside universities. Among main Polish philosophers connected with the 19th century University of Warsaw were Adam Zabellewicz and Henryk Struve.

Interwar period
After 1918, when Poland regained independence, University of Warsaw was reorganized. Chairs of philosophy were held by Jan Łukasiewicz, Władysław Tatarkiewicz, Tadeusz Kotarbiński, Stanisław Leśniewski, Kazimierz Ajdukiewicz and Stanislaw Schayer.

Initially, philosophical education were organized in the Faculty of Historical-Philosophical Studies (1915–16), soon transformed into the Faculty of Philosophical Studies (1916–27), and then into the Faculty of the Humanities (Tatarkiewicz, Kotarbiński and Schayer) and the Faculty of Mathematical Studies and Physics (Łukasiewicz, Leśniewski and Ajdukiewicz).

Other important philosophers teaching in Warsaw were Alfred Tarski, Henryk Elzenberg, Maria Ossowska and Stanisław Ossowski. Worldwide renown in logic and analytic philosophy was enjoyed by the Warsaw School of Logic, part of the philosophical movement of Lvov-Warsaw School.

During the German occupation of Warsaw secret courses of philosophy were conducted by Łukasiewicz, Tatarkiewicz, Kotarbiński and others.

History after 1945
After 1945, during the stalinist era, due to political predominance of Marxist philosophy in Poland some professors were partially prohibited from pursuing didactic activity. After the Polish October (1956) a separate Faculty of Philosophical Studies (1954–65) emerged from the Faculty of Arts and many leading philosophers were allowed to teach. It was subsequently transformed into the Faculty of Philosophical-Sociological Studies (1965–68).

In the 50s and 60s, the Warsaw School of the History of Ideas emerged. To this informal group of non-analytical philosophers belonged mainly former Marxists (called "revisionist"), inspired to some extent by the ideas of Tatarkiewicz and Ossowskis. After the Polish March (1968), when many "revisionist" Polish philosophers and sociologists (for example Leszek Kołakowski, Zygmunt Bauman, Adam Schaff) participated in the events, philosophy at Warsaw University was subjected to a thorough reorganization. Chairs were renamed to departments and the Faculty of Philosophical Studies were forcibly joined with the Faculty of Sociology, within which the Institute of Philosophy was established.

In the post-war period the tradition of Lvov-Warsaw School was also continued. To the most important philosophers and logicians of the post-war period connected with the University of Warsaw belong Kazimierz Ajdukiewicz, Zdzisław Augustynek, Bronisław Baczko, Marek Fritzhand, Henryk Jankowski, Andrzej Kasia, Leszek Kołakowski, Władysław Krajewski, Tadeusz Kroński, Jan Legowicz, Stefan Morawski, Elżbieta Pietruska-Madej, Marian Przełęcki, Adam Schaff, Marek Siemek, Adam Sikora, Roman Suszko, Klemens Szaniawski and Bogusław Wolniewicz.
