Jana Franciszka Drewnowskiego filozofia matematyki i logiki
Jan Franciszek Drewnowski’s philosophy of mathematics and logic

Summary/Abstract: This paper illustrates and critically evaluates Jan Franciszek Drewnowski’s philosophical views on mathematics and logic. It is based on four sources. The main source is his “Zarys programu filozoficznego” (“Outline of a Philosophical Program”) (1934). Further sources include two of Drewnowski’s papers, “Stosowanie logiki symbolicznej w filozofii” (“Application of symbolic logic in philosophy”) (1965) and “Uwagi o stosowaniu logiki symbolicznej” (“Remarks on applying symbolic logic”) (1967), as well as fragments from his diary. This paper aims to show how Drewnowski understood mathematics and mathematical theories, how he conceived logic and its role in science, as well as to what extent he was familiar with contemporary achievements in mathematical logic and the foundations of mathematics and his awareness of their relevance for the philosophy of mathematics.
