2The Semantics Controversy at the 1935 Paris CongressPhilosophia Scientiae 22 199-211. 2018.Les débats qui ont eu lieu, lors du Congrès de philosophie scientifique de 1935, sur la sémantique et sa portée philosophique présentent un grand intérêt historique pour deux raisons. Tout d’abord, on s’accorde à y reconnaître un des évènements majeurs du congrès. En second lieu, et de façon plus substantielle, ils ont joué un rôle décisif dans le développement de la sémantique comme discipline philosophique. C’est Carnap qui en a pris l’initiative en invitant Tarski à donner deux conférences. C…Read more

38Reism and Le'sniewski's OntologyHistory and Philosophy of Logic 7 (2): 167-176. 1986.This paper examines relations between reism, the metaphysical theory invented by Tadeusz Kotarbi?ski, and Le?niewski's calculus of names. It is shown that Kotarbi?ski's interpretation of common nouns as genuine names, i.e. names of things is essentially based on Le?niewski's logical ideas. It is pointed out that Le?niewskian semantics offers better prospects for nominalism than does semantics of the standard firstorder predicate calculus

5Some Philosophical Aspects of Semantic Theory of TruthIn Urszula Wybraniec-Skardowska & Ángel Garrido (eds.), The Lvov-Warsaw School. Past and Present, Springer- Birkhauser,. pp. 373-389. 2018.The semantic theory of truth, formulated by Alfred Tarski in the 1939s, is primarily a mathematical theory. On the other hand, it also has a considerable philosophical content. This paper presents the second aspect of this theory. It can be shown that several traditional philosophical issues pertaining to the concept of truth can be illuminated by Tarski’s account of truth. It concerns, for instance, the idea of correspondence, the relation of truth and logic, the problem of the relativity/absol…Read more

16Polish Logicians in the Years 1918-1948 on Social Functions of LogicFilozofia Nauki 30 (1): 67-81. 2022.The Polish School of Logic flourished in the period 1920-1939. Philosophically, it was influenced by Kazimierz Twardowski, professor at the University of Lwow (now Lviv in Ukraine), who established the Lwow-Warsaw School, to which the mentioned logical group belonged. Twardowski claimed that logic is very important in every kind of human activity, professional as well as private. Hence, every argument should be clearly formulated and proceed by correct inferential rules. These postulates involve…Read more

8Jan Łukasiewicz, Sur la Logique des stoïciensPhilosophie Antique 11 11-15. 2011.Jan Łukasiewicz a élaboré un programme de recherche portant sur l’histoire de la logique. À son avis, la logique mathématique contemporaine (modern) est en continuité directe avec la logique formelle du passé. En conséquence, une interprétation correcte et fidèle des idées anciennes exige une application des outils logiques contemporains. Autrement dit, de bonnes études historiques sur la logique doivent consister à examiner la logique d’autrefois à travers les lunettes logiques contemporaine...

16Beyond logic there is only nonsenseStudies in East European Thought 74 (2): 165-172. 2021.This paper provides an interpretation of Father Bocheński’s saying “Beyond logic there is only nonsense.” He considered the battle against superstitions of various kinds as one of the most important intellectual and social duties. The phrase in itself suggests that logic is a weapon in the mentioned battle. Logic is understood broadly, that is, as semantics, formal logic and the methodology of science, and was considered by Bocheński as the main instrument of rational philosophy. Hence, the form…Read more

2Searle and Conte on Deriving Ought from IsIn Paolo Di Lucia & Edoardo Fittipaldi (eds.), Revisiting Searle on Deriving “Ought” From “Is”, Springer Verlag. pp. 239-251. 2021.The view I defend here is that ought cannot be logically derived from is. This can be justified at the level of very elementary deontic logic, as captured by the generalized logical square. This logical fact can be stated as the Hume thesis. However, the inspection of a given normative order may suggest that something exists. On the other hand, such conclusions can be fallible. In order to argue that ought is derivable from is, one must use extralogical elements and, in particular, definitions. …Read more

9Metalogical Remarks on InductionAxiomathes 31 (6): 763-777. 2021.The problem of induction belongs to the most controversial issues in philosophy of science. If induction is understood widely, it covers every fallible inference, that is, such that its conclusion is not logically entailed by its premises. This paper analyses so-called reductive induction, that is, reasoning in which premises follow from the conclusion, but the reverse relation does not hold. Two issues are taken into account, namely the definition of reductive inference and its justification. T…Read more

18Limitations of Formal (Logical) SemanticsStudia Semiotyczne—English Supplement 31 73-90. 2020.According to the received view formal semantics applies to natural language to some extent only. It is so because natural language is inherently indefinite, in particular, its expressions are ambiguous, vague and admits departures from syntactic rule. Moreover, intensional contexts occur in ordinary language—it results in limitations of the principle of compositionality. The ordinary conversation appeals to various principles, for instance, Grice’s maxims which exceed logical formalism. Thus, or…Read more
