17Ways of Dealing with Non-existenceGrazer Philosophische Studien 50 (1): 113-127. 1995.Non-existence provides big problems for ontology and modest for logic. Logical problems of non-existence consist in licensing inferences in which sentences with empty terms are involved. The standard predicate logic solves this question by presupposing that every individual constant has an object to which it refers. This means that empty domains are excluded from semantics for the first-order logic. However, there is a temptation to consider logic without existential presuppositions.The ontologi…Read more

74Logic as Calculus Versus Logic as Language, Language as Calculus Versus Language as Universal Medium, and Syntax Versus SemanticsLogica Universalis 6 (3-4): 587-596. 2012.This paper discusses the distinctions indicated in its title. It is argued that the distinction between syntax and semantics is much more important for the present situation in logic than other distinctions. In particular, doing formal syntax and formal semantics requires the use of an informal melanguage based on ordinary mathematics

10Philosophical Logic in Poland (edited book)Kluwer Academic Publishers. 1994.Poland has played an enormous role in the development of mathematical logic. Leading Polish logicians, like Lesniewski, Lukasiewicz and Tarski, produced several works related to philosophical logic, a field covering different topics relevant to philosophical foundations of logic itself, as well as various individual sciences. This collection presents contemporary Polish work in philosophical logic which in many respects continue the Polish way of doing philosophical logic. This book will be of i…Read more

11Naturalism and ReismDialogue and Universalism 17 (1/2): 13-19. 2007.This paper compares Kotarbiński’s reism and naturalism. It argues that basic ontological and epistemological reistic principles fit naturalism very well. In particular, the thesis claiming that there are only spatiotemporal things (bodies) gives a very simple naturalistic account of reality. Radical realism defended by Kotarbiński is a version of direct realism, a view about perception which is very accurate for naturalism. On the other hand, since difficulties of reism are also problems for nat…Read more

Czy filozof analityczny potrzebuje epistemicznej viagry?Filozofia Nauki 1. 2000.The paper is a reply to Jan Czerniawski's paper „On epistemic impotence of analytical philosophy” (Filozofia Nauki 3-4/1998). Czerniawski argues that the analytic method consists either in arbitrary stipulations or in the appeal to linguistic intuitions. He claims that the latter are subjective and moreover they cannot help deciding objective problems, while the former are an arbitrary creation of truth. Hence, the analytic method has to be assisted by an intuitive insight into objective situati…Read more

1Metalogika i teorie empiryczneRoczniki Filozoficzne 54 (2): 299-310. 2006.Metalogic (as a part of metamathematics) deals with the properties of formalised mathe- matical theories. Its applicability to empirical theories is an object of debate. The paper defends the moderate view that although it is difficult to expect such spectacular results, as have been obtained on mathematical theories, nevertheless the metalogical analysis of the first two gives us some benefits. Empirical theories may be understood as axiomatised sets of propositions closed with the operation of…Read more
