context_page_description: The Lwów–Warsaw School was a Polish school of thought founded by Kazimierz Twardowski in 1895 in Lemberg, Austro-Hungary.
  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. It has produced some of the leading logicians of the twentieth century such as Jan Lukasiewicz, Stanislaw Lesniewski, and Alfred Tarski, among others. Its members did not only contribute to the techniques of logic but also to various domains that belong to the philosophy of language.
