The Philosophy of Mathematics and Logic in the 1920s and 1930s in Poland

The aim of this book is to present and analyze philosophical conceptions concerning mathematics and logic as formulated by Polish logicians, mathematicians and philosophers in the 1920s and 1930s. It was a remarkable period in the history of Polish science, in particular in the history of Polish logic and mathematics. Therefore, it is justified to ask whether and to what extent the development of logic and mathematics was accompanied by a philosophical reflection. We try to answer those questions by analyzing both works of Polish logicians and mathematicians who have a philosophical temperament as well as their research practice. Works and philosophical views of the following Polish scientists will be analyzed: Wac¿aw Sierpi¿ski, Zygmunt Janiszewski, Stefan Mazurkiewicz, Stefan Banach Hugo Steinhaus, Eustachy ¿yli¿sk and Leon Chwistek, Jan ¿ukasiewicz, Zygmunt Zawirski, Stanis¿aw Le¿niewski, Tadeusz Kotarbi¿ski, Kazimierz Ajdukiewicz, Alfred Tarski, Andrzej Mostowski and Henryk Mehlberg, Jan Sleszy¿ski, Stanis¿aw Zaremba and Witold Wilkosz. To indicate the background of scientists being active in the 1920s and 1930s we consider in Chapter 1 some predecessors, in particular: Jan ¿niadecki, Józef Maria Hoene-Wröski, Samuel Dickstein and Edward Stamm.
