Lwów–Warsaw school
The Lwów–Warsaw School (Polish: Szkoła Lwowsko-Warszawska) was an interdisciplinary school (mainly philosophy, logic and psychology) founded by Kazimierz Twardowski in 1895 in Lwów, Austro-Hungary (now Lviv, Ukraine). Though its members represented a variety of disciplines, from mathematics through logic to psychology, the Lwów–Warsaw School is widely considered to have been a philosophical movement.
