We have to deal with numerous signs in everyday life, given us both by the nature – as, for example, clouds being a sign of upcoming rain, and also traditional, conventional signs and created by ourselves for better communication. A sign is a perceptible arrangement of things or a phenomenon caused by someone else for the reason that some set expression or formed customary rules govern combining a definite type of thoughts with this arrangement of things or the phenomenon.

Among the non-classical logics, the intuitionistic one stands out in many ways. First of all, because of its properties, it is grateful subject of formal analysis. Moreover, there is small, but very significant group of mathematicians and philosophers who claim that intuitionistic logic captures the reasoning utilized in mathematics better than classical one. This article reveals the origins of intuitionistic propositional calculus – it was an outcome of formalization of certain ideas about foundations of mathematics. A large part of the article is devoted to Glivenko’s Theorem – somewhat forgotten, but extremely interesting formal result regarding the relationship between the two logical calculi: classical and intuitionistic propositional logic.

Co to jest prawda?

This question has entered to history of the European culture not only in the version of Socrates, Plato and Aristotle, but also as Pilate’s question. However, is this question every time about the same? Or is its intellectual version, which we deal with in philosophy, equivalent with the religious formula? Ancient philosophers, such as Descartes or Aristotle have already studied the question of truth. Truth is not an issue completely clear for man. Despite so many clear definitions, it does not give us full form of the notion of truth. All these centuries various inquires did not give us any answers. Every of definitions of truth shows us how to act, and according to which rules. We can agree on the classic definition of truth or reject it.

Pojęcie nazwy oraz funktora

Syntactic categories fulfil different roles in constructing compound expressions. Sentences and names, and also some functors are syntactic categories. Sentences are expressions which state that something is this way and not another. Therefore, in the logical sense, a sentence is a following statement: “The earth is a planet”. Sentences (expressions) are intensional when they do not deserve a feature of extensionality. There can be sentences saying about conditions of the mind, causal or time relationships etc. Therefore, they are intensional because their logical value (i.e. truth or falsity) depends not only on component elements (e.g. from truth / falsity of clauses of the compound sentence), but also on different factors. Between the modules of this expression (e.g. between the component sentences of the compound sentence) some more different relations occur. These sentences get in relationships between them, e.g. in the cause and effect relationship - as a logical implication relation. Therefore, the logical value of these sentences goes beyond simple logical deductions, and according to some theories goes beyond logic itself.

This article is confrontational with the theses presented in the paper: O pewnym (chybionym) studium przypadku [About a (wrong) case study ] (Chybińska 2017), which is the answer to the issues presented in the article: Etyka w przekładzie specjalistycznym a kompetencje tłumacza tekstów specjalistycznych - studium przypadku [Ethics in specialized translation and competence of specialist translator: case study] (Boroch 2017). In this article (Boroch 2017), the methodological principles in the specialist translation and the substantive and ethical consequences of their violation have been presented. Exemplary material was the Polish translation of Henryk Hiż's article: Peirce's Influence on Logic in Poland (Hiż 1997, 264–270) published in ”Studia z Filozofii Polskiej” in 2015 (Hiż 2015, 21–29) along with a biographical section (Chybińska 2015, 29–33) which both constitute a coherent publication. The article has raised the following issues: (1) the lack of justification of the basis of translation, i.e. the primacy of the manuscript over the printed version, that is the last one controlled by the author; (2) inconsistency with regard to termination of translation; (3) unauthorized introduction of a Polish neologism “dylematyczny” derived from the (non-existent) English lexical unit “dylemmatic” (Sic!); (4) proposal of the notation of Peirce's law: (p, q, r ) (Sic!).
