Leading authors in their fields present an interdisciplinary panorama of vital themes of the philosophy of language and track their historical origins. This book gives new life to historical ideas and additional depth to current debates.

This collection celebrates the centenary of the Lvov-Warsaw school, established by Kazimierz Twardowski in Lvov in 1895. This school belongs to analytic philosophy and successfully worked in all branches of philosophy. The Warsaw school of logic became perhaps the most important part of Twardowski's heritage. Lesniewski, Lukasiewicz and Tarski, leading Polish logicians, achieved results which essentially influenced the development of contemporary logic. A close connection of logic and philosophy was a typical feature of the Lvov-Warsaw school. The papers included in the collection deal with all directions of research undertaken by Polish analytic philosophers. Special attention is paid to logic and comparisons with other philosophical movements, particularly with Brentanism, which was one of the sources of the Lvov-Warsaw school.

This book presents the heritage of the Lvov-Warsaw School from both the historical and the philosophical perspective. The historical view focuses on the beginnings and the dramatic end of the School brought about by the outbreak of World War II. The philosophical view, on the other hand, encompasses a broad spectrum of issues, including logical, epistemological, axiological, and psychological problems, revealing the interdisciplinary nature of studies carried out by Kazimierz Twardowski and his students. With thirteen diverse and original essays this volume is split into three parts: History, Culture and Axiology; Psychology; and Logic and Methodology. Exploring not only the history of philosophy represented by the Lvov-Warsaw school, the book also reflects on the condition of contemporary philosophy from the perspective of concepts developed by its representatives. Furthermore, the studies presented in this book delve into problems of contemporary science and its distinctive interdisciplinary character. This volume is, therefore, not only a collection of analyses of the Lvov-Warsaw School philosophy, but also an investigation into the interdisciplinarity of science and philosophy itself.

“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. This led above all [...] to collaborations with mathematicians, so that the Lvov school of philosophy would gradually evolve into the Warsaw school of logic [...]. Twardowski taught his students, too, to respect and to pursue serious research in the history of philosophy, an aspect of the tradition of philosophy on Polish territory which is illustrated in such disparate works as [Jan] Łukasiewicz’s ground-breaking monograph on the law of non-contradiction in Aristotle and [Władysław] Tatarkiewicz’s highly influential multi-volume histories of philosophy and aesthetics [...] The term ‘Polish philosophy’ is a misnomer [...] for Polish philosophy is philosophy per se; it is part and parcel of the mainstream of world philosophy – simply because [...] it meets international standards of training, rigour, professionalism and specialization.” – Barry Smith (from: “Why Polish Philosophy does Not Exist”)
