The Lwów–Warsaw School (Polish: Szkoła Lwowsko-Warszawska) was a Polish school of thought founded by Kazimierz Twardowski in 1895 in Lemberg (Polish name: 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. 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.
Polish philosophy and the Lwów–Warsaw school were considerably influenced by Franz Brentano and his pupils Kazimierz Twardowski, Anton Marty, Alexius Meinong, and Edmund Husserl. Twardowski founded the philosophical school when he became the chair of the Lwów University.
The Lwów–Warsaw School began as a general philosophical school but steadily moved toward logic. The Lwów–Warsaw school of logic lay at the origin of Polish logic and was closely associated with or was part of the Warsaw School of Mathematics. According to Jan Woleński, a decisive factor in the school's development was the view that the future of the Polish school of mathematics depended on the research connected with the new branches of the field such as set theory and topology, which are closely related to mathematical logic. The "philosophical branch" followed Twardowski's tradition and produced notable thinkers such as Bronisław Bandrowski, who addressed the problem of induction and Tadeusz Kotarbinski, who is known for developing Reism.
In the 1930s Alfred Tarski initiated contacts with the Vienna Circle. Tarski, the most prominent member of the Lwów–Warsaw School, has been ranked as one of the four greatest logicians of all time, along with Aristotle, Gottlob Frege, and Kurt Gödel.
The school's work was interrupted by the outbreak of World War II. Despite this, its members went on to fundamentally influence modern science, notably mathematics and logic, in the post-war period. Tarski's description of semantic truth, for instance, has revolutionized logic and philosophy.
In contemporary Polish learning, the philosopher Jan Woleński considers himself close to the School's heritage. In 2013 Woleński was awarded by the Foundation for Polish Science for his comprehensive analysis of the work of the Lwów–Warsaw school and for placing its achievements within the international discourse of contemporary analytic philosophy.
