Abstract
Professor Barbara Stanosz was a years-long lecturer at the Institute of Philosophy, University of Warsaw. In her work she mainly – but not exclusively – focused on the theory of language, particularly semantics and the issues of logical description of phrases in language (the problem of logical form). She was an author of renowned textbooks, including the famous Ćwiczenia z logiki [Exercises in logic], a vastly popular exercise book helping students to acquire the material on propositional logic, predicate logic and set theory. It is worth mentioning that besides her academic and teaching activities, she was also a social activist and a great supporter of the state’s worldview neutrality. She died on 7th June 2014.
