4. One might think that by extending the notion of logic to its limits, logicians behave like “logical imperialists” who try to invade other branches of mathematics. This is not so. Logic and its methods are both the source of inspiration and the basic research tool for mathematics. Applying the term “logic” to the foundations of mathematics enables the experts on foundational issues to establish their scientific identity. It also enables them to see their highly varied field of research as a whole that differs from the rest of mathematics.
5. It was formed by a group of philosophers, logicians, sociologists, and other scientists who upheld the tradition initiated by the seminars and writings of Kazimierz Twardowski, an eminent psychologist and philosopher from Lvov University. Precise analysis and lucid argument were the virtues that Twardowski considered indispensable both in scientific inquiry and philosophical analyses. Logic was regarded as the basic tool for meeting this requirement. It is not odd then that the Lvov-Warsaw School attracted logicians while at the same time logicians and their works essentially influenced the School. An impressive monograph on the School was written by Jan Wolenski, Logic and Philosophy in the Lvov-Warsaw School, Kluwer 1989. A brief and informative article on Polish logic of the interwar period can be found in The Routledge Encyclopaedia of Philosophy, vol 7, Routledge, London and New York, 1998, 498–500, “Polish Logic” by J. Zygmunt.
