As a scholar, he left the school of Franz Brentano and influenced significantly the representatives of early analytical philosophy. His interdisciplinary philosophical program also turns out to be attractive today. The comprehensive work of Twardowski includes dissertations in all areas of philosophy (from logic, through ontology and epistemology, to aesthetics and ethics) and its history, as well as works in the field of psychology and didactics.

As a teacher, he became a master of several generations of philosophers and, more broadly, humanists of the kind Jan Łukasiewicz, Władysław Witwicki, Zygmunt Zawirski, Stefan Baley, Stanisław Leśniewski, Tadeusz Kotarbiński, Władysław Tatarkiewicz, Tadeusz Czeżowski, Kazimierz Ajdukiewicz and Izydora Dąmbska. They became the backbone of a world-famous intellectual formation known as the “Lviv-Warsaw School”.

As a citizen, he performed many public functions in an exemplary manner, playing an extremely important role in the cultural life of Lviv and Galicia, and then of the reborn Poland. For his entire milieu, he was a model of an unwavering moral attitude.

The page you have in front of you is trying to comprehensively show the activity of Kazimierz Twardowski and the value of his legacy.
