    On Deontic Logic.Leon Gumański - 1980 - Studia Logica 39 (1):63 - 75.
    Some requirements concerning deontic logic are formulated and discussed. Stress is laid on the need to distinguish between theories and deductive systems. It is argued that deontic theories need not be closed under the rule of detachment. Two deontic calculi, called DSC1, DSC2, are presented and talked over.

    An Extension of the Deontic Calculus DSC.Leon Gumański - 1983 - Studia Logica 42 (2-3):129 - 137.
    The chief aim of the paper is to extend the calculusDSC 1 (see [4]) in such a way as to satisfy all the requirements listed in [4] as well as a further stipulation — called the principle of uninvolvement — to the effect that neither deontic compatibility nor deontic incompatibility of codes (see [2]) should be presupposed in deontic logic.

    A New Approach To Realistic Epistemology.Leon Gumanski - 1989 - Dialectica 43 (1‐2):193-210.
    SummaryMain theses and assumptions: I. The so called sense‐data do not exist; II. In sensory cognition we perceive immediately objects, their features and relations; III. Each simple cognitive situation comprises cognitive conditions. Accordingly, a full simple sentence ought to have the shape: p“under conditions C” where p has one of the forms ‐ ; IV The subject should be treated as an abstract entity, not be identified with the man; V. Existence is an empirical feature; VI. Reality is the totality (...)

  18. To Be or Not to Be? Is That the Question?: And Other Studies in Ontology, Epistemology and Logic.Leon Gumański (ed.) - 1999 - Rodopi.
    This volume may be of interest for all those who wish that philosophy had a scientific character. As an adherent of the Polish Lvov-Warsaw Philosophical School, the author of this collection of papers endeavours to clarify some basic notions of epistemology, ontology and psychology of cognitive acts, such as "judgment", "existence", "being" etc. In his investigations he refrains from unnecessary rejection of common-sense knowledge but at the same time searches for suitable patterns in contemporary sciences. Regarding formal logic as a (...)
