Tadeusz Kotarbiński

Tadeusz Marian Kotarbiński (; 31 March 1886 – 3 October 1981) was a Polish philosopher, logician and ethicist.

A pupil of Kazimierz Twardowski, he was one of the most representative figures of the Lwów–Warsaw School, and a member of the Polish Academy of Learning (PAU) as well as the Polish Academy of Sciences (PAN). He developed philosophical theory called ''reism'' () and an ethical system called independent ethics. Kotarbiński also contributed significantly to the development of praxeology.

Henryk Greniewski and Kazimierz Pasenkiewicz were doctoral students under Kotarbiński. Provided by Wikipedia
