  1. Ryszard Wójcicki (2011). Is There Any Need for Non-Classical Logic in Science? Grazer Philosophische Studien 12:119-129.
    The role of classical logic as the base of formalized scientific theories seems to be unshakable. Yet legitimate doubts about its universal applicability in science have resulted in the development of alternative systems, among which constructive and modal logic are discussed in syntactic and semantic terms.

    The paper brings a critical analysis of the assumptions on which K. Ajdukiewicz (1934) based his considerations concerning the theory of meaning and proposes to look at these problems from a new research perspective. The considerations sought to analyse the modes of accepting propositions which call for a contact with empirical reality, therefore to apply some empirical procedures (observations, tests, experiments).

    In what follows, I will address three fundamental questions regarding the theory of knowledge. They are as follows: What is knowledge? How can it be represented? How may one evaluate its quality? In this essay I outline a certain conceptual framework within which, I believe, these questions should be examined.

    Ryszard Wójcicki's book „Ajdukiewicz. A Theory of Meaning” opens a series of publications Filozofia polska XX wieku [Polish Philosophy of XXth Century], created by Wójcicki. The main subject of the book is a theory of the meaning of linguistic expressions, which was formulated in the thirties and is known as a directival theory of meaning. The aim that the author has set for himself is not only to present and popularise that theory (these aims are implied by the character of (...)

    The two main points of this contribution are the following: (1) Applied mathematical theories might complement physical theories in an essential way; some applied mathematical theories allow us to understand phenomena we are unable to explain by resorting to physical theories alone, (2) In the case of social sciences it might be necessary to account for examined phenomena by resorting to the idea of goal-oriented activity (the causal approach typical for natural science might be unsatisfactory). Weinberg's idea of grand reductionism (...)

    The central claim of this paper is the following. There are two different types of notions applied in science, and in fact in any discourse whatsoever. Some of the notions are veristic, i.e. they refer to some specific fairly well defined entities (individual objects, species, relations, systems, regularities, etc.). But there are also heuristic notions that serve the users to call attention to the fact that a specific situation can be accounted for, or even less - there is a chance (...)

    This paper was written with two aims in mind. A large part of it is just an exposition of Tarski's theory of truth. Philosophers do not agree on how Tarski's theory is related to their investigations. Some of them doubt whether that theory has any relevance to philosophical issues and in particular whether it can be applied in dealing with the problems of philosophy (theory) of science.In this paper I argue that Tarski's chief concern was the following question. Suppose a (...)
