Między determinizmem a prawdopodobieństwem – analiza poglądów Jana Łukasiewicza

Abstract

Between determinism and probability - analysis of the philosophical views of Jan Łukasiewicz: In the contemporary philosophical debate about probability, one of the main problems concerns the relation between objective probability and determinism. Is it possible for objective probability and determinism to co-exist? This is one of the questions this dispute tries to answer. The scope of discussion is conducted between advocates of a positive answer (compatibilist) and co-existence opponents (incompatibilist). In the early twentieth century, many logicians also developed topics regarding probability and determinism. One of them was the outstanding Polish logician and philosopher — Jan Łukasiewicz. The general purpose of this paper is to analyse and implement Łukasiewicz’s views regarding determinism and probability in the contemporary field of this problem. I will try to show the relation between his interpretations of these concepts and in consequence his attempt to confront them. As a result of the above analysis, I present some different positions (located in the fields of logic and semantics) in the contemporary discourse about the relation between objective probability and determinism. Moreover, I will present Łukasiewicz’s views about this relation and the consequence of these solutions in the field of logic.
