    Logic and experience in the light of dialogic logic
    Bulletin of the Section of Logic 12 (4): 173-178. 1983.
    There seems to be something mysterious about applications of for- mal systems, including those of logic, to empirical reality 1 . If logic is to be applied to empirical situations, like those described in an ordinary lan- guage, then { it seems to some people { its statements cannot be necessary, or analytic, propositions. However, they are both applicable and necessary. This supposed puzzle constitutes a signicant part of the problem of philo- sophical foundations of logic 2 . To this mind of t…Read more

    Rational beliefs as produced by computational processes
    Foundations of Science 2 (1): 87-106. 1997.
    Intelligent problem-solving depends on consciously applied methods of thinking as well as inborn or trained skills. The latter are like resident programs which control processes of the kind called (in Unix) daemons. Such a computational process is a fitting reaction to situations (defined in the program in question) which is executed without any command of a computer user (or without any intention of the conscious subject). The study of intelligence should involve methods of recognizing those be…Read more

    On Accelerations in Science Driven by Daring Ideas: Good Messages from Fallibilistic Rationalism
    Studies in Logic, Grammar and Rhetoric 40 (1): 19-41. 2015.
    The first good message is to the effect that people possess reason as a source of intellectual insights, not available to the senses, as e.g. axioms of arithmetic. The awareness of this fact is called rationalism. Another good message is that reason can daringly quest for and gain new plausible insights. Those, if suitably checked and confirmed, can entail a revision of former results, also in mathematics, and - due to the greater efficiency of new ideas - accelerate science’s progress. The awar…Read more

Powstał on pod tą nazwą u progu nowożytności, a częściowo miał antycypacje w starożytności i średniowieczu. Głównymi jego rzecznikami byli Kartezjusz i Leibniz. Podejście Leibniza jest radykalnie formalistyczne, a przez to nadające sie do realizacji maszynowej, podczas gdy Kartezjusza - zdecydowanie antyformalistyczne. Artykuł koncentruje się na projekcie Leibniza jako tym, który ma kont…Read more

    Universal Spaces for Classes of Scattered Eberlein Compact Spaces
    with Murray Bell
    Journal of Symbolic Logic 71 (3). 2006.
    We discuss the existence of universal spaces (either in the sense of embeddings or continuous images) for some classes of scattered Eberlein compacta. Given a cardinal κ, we consider the class Sκ of all scattered Eberlein compact spaces K of weight ≤ κ and such that the second Cantor-Bendixson derivative of K is a singleton. We prove that if κ is an uncountable cardinal such that κ = 2&ltκ, then there exists a space X in Sκ such that every member of Sκ is homeomorphic to a retract of X. We show …Read more
