    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 (...)

    This paper was presented at the Annual Conference of the Australian Association for Logic, Melbourne, November, 1979. The present note being complementary to [1], I shall only brie y recall the key notions to be exploited here, and for more details the reader is advised to consult [1]. By a propositional logic we mean a couple , where L is a propo- sitional language and C a structural consequence de- ned on L. A couple W = is said to be (...)

    Is There Any Need for Non-Classical Logic in Science?Ryszard Wójcicki - 1981 - Grazer Philosophische Studien 12 (1):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.

    Physics, Theoretical Knowledge and Weinberg's Grand Reductionism.Ryszard Wójcicki - 1998 - Foundations of Science 3 (1):61-77.
    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 (...)

    What Do We Know?Ryszard Wójcicki - 2001 - The Proceedings of the Twentieth World Congress of Philosophy 2001:69-77.
    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.

    I shall assume that the reader is familiar with the notions dened in [2] and [3]. A consequence C dened over a propositional language L will be said to be d-structural i the consequence dC dual with respect to C is structural. The following propositions holds true.

    Should Tarski’s Idea of Consequence Operation Be Revised?Ryszard Wójcicki - 1999 - Vienna Circle Institute Yearbook 6:231-242.
    Tarski’s papers, in which he examines the idea of a consequence operation Cn,divide into two groups. One of them is formed by the papers that offer an analysis of the general idea of the consequence operation. Resorting to fundamental ideas of logical semantics, Tarski explains what, in his view, it means to say that a formula a of a language L is a logical consequence Cn of a set of formulas X of that language. Under the definition he proposed Cn (...)

    Empiryczne sposoby uznawania zdań. (Na marginesie teorii Ajdukiewicza).Ryszard Wójcicki - 2006 - Roczniki Filozoficzne 54 (2):413-426.
    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).
