Ajdukiewicz o stosowalności czystej logiki

The paper is an analysis of the arguments contained by Kazimierz Ajdukiewicz in his article on the applicability of pure logic to philosophical issues (1934). The author argues that philosophers in support of their claims can not use pure logic statements as evidence. Because theses formulate their common language, they can only appeal to the logic of everyday language, an alternative to the modern systems of symbolic logic.
