Logic of language and philosophy of language in 20th-century Poland

The logic of language and the philosophy of language in 20th-century Poland ran in two mainstreams, the so-called Lvov-Warsaw school and and that of phenomenological thought. The former was dominant, the latter was represented mainly by the work of Roman Ingarden (1903–1970). Among works of the Lvov-Warsaw school, the present paper considers the most important achievements of its founder, Kazimierz Twardowski (1866–1938), and the oldest generation of his disciples: Leśniewski (1886–1939), Kotarbiński (1886–1981), Ajdukiewicz (1890–1963), and Izydora Dąmbska (1904–1983), as well as Alfred Tarski (1902–1983) who, in philosophy, was a disciple of Jan Łukasiewicz (1878–1956), Leśniewski and Kotarbiński. The paper is limited to the discussion of the most important of their reflections on natural language, in particular to what is most characteristic of them: elaborated and deep analyses of semantic sections connected with epistemological ones, and pragmatic sections connected with psychological ones, all presented with great attention to clarity, precision and comprehensibility of formulations. Major semantic conceptions of Ingarden were also mentioned: the theory of meaning as a relation between an intending object and an intentional object, as well as semantic differences between a name, verb and sentence.
