"The influence of [Kazimierz] Twardowski on modern philosophy in Poland is all-pervasive. Twardowski instilled in his students a passion for clarity [...] and seriousness. He taught them to regard philosophy as a collaborative effort, a matter of disciplined discussion and argument, and he encouraged them to train themselves thoroughly in at least one extra-philosophical discipline and to work together with scientists from other fields, both inside Poland and internationally.

The volume contains almost thirty papers by Kazimierz Twardowski (1866-1938), the founder of the Lvov-Warsaw School. The papers are published in English for the first time. They stem from the Lvov period, which is often contrasted with the earlier Vienna period of Twardowski's scientific activity.

Izydora Dąmbska (1904-1982) was a Polish philosopher; a student of Kazimierz Twardowski, and his last assistant. Her output consists of almost 300 publications.

Dąmbska's approach to philosophical problems reflected tendencies that were characteristic of the Lvov-Warsaw School. She applied high methodological standards but has never limited the domain of analyzed problems in advance. The present volume includes twenty-eight translations of...
