Kazimierz Ajdukiewicz

Born 12 Dec 1890; died 12 Apr 1963 at age 72.Polish logician and semanticist who was the chief contributor to the Warsaw school of philosophy and logic, and is credited with developing in 1920 the first deductive theory for the study of logic based on syntax. The dominant theme of Ajdukiewicz's thought was the problem of the dependence of our knowledge and conception of knowledge on language. His main contributions are in the field of logical syntax (with the theory of semantical categories) and in epistemology, with the so-called “radical conventionalism,”a doctrine where he claimed that there exist conceptual apparatuses which are not intertranslatable and that scientific knowledge grows through the replacement of one such conceptual apparatus by another.
