  1. Leśniewski-Quantifiers and Modal Arguments in Legal Discourse.Burkhard Schäfer - 1998 - Logic and Logical Philosophy 6:133.
    Following an idea first proposed by Jerzy Wróblewski, this paperexamines the usefulness of formal logic for comparative legal analysis. Subject of the comparison are the doctrines of mistake and attempt in Germanand English criminal law. These doctrines are distinguished by the interaction of deontic, epistemic and alethic modalities. I propose a purely extensional logic which is based on Leśniewski’s substitutional interpretation ofquantification to analyse differences in the logical structure of the variouscriminal law doctrines.

  • Definitions And Contradictions. Russell, Poincaré, And Lesniewski.François Lepage - 2008 - The Baltic International Yearbook of Cognition, Logic and Communication 4.
    This paper is composed of two independent parts. The first is concerned with Russell’s early philosophy of mathematics and his quarrel with Poincaré about the nature of their opposition. I argue that the main divergence between the two philosophers was about the nature of definitions. In the second part, I briefly present Le!niewski’s Ontology and suggest that Le!niewski’s original treatment of definitions in the foundations of mathematics is the natural solution to the problem that divided Russell and Poincaré.

  • A Lesniewskian Reading of Ancient Ontology: Parmenides to Democritus.Paul Thom - 1986 - History and Philosophy of Logic 7 (2):155-166.
    Parmenides formulated a formal ontology, to which various additions and alternatives were proposed by Melissus, Gorgias, Leucippus and Democritus. These systems are here interpreted as modifications of a minimal Le?niewskian ontology.

  • Interpretations of Leśniewski's Ontology.V. Frederick Rickey - 1985 - Dialectica 39 (3):181-192.
    SummaryThis article proposes to clarify the problem of interpreting Lesniewski's ontology. A distinction is made between two kinds of interpretation: substitutional and “natural”. Substitutional interpretation is shown to involve difficulties and limitations. A “natural” ontology, the major principles of which are presented here, is shown to be of considerable interest.

  • A Semantics for Ontology.Peter M. Simons - 1985 - Dialectica 39 (3):193-215.
    SummaryLeśniewski presented his logical systems in a way which conformed to his nominalism, so the question arises whether Leśniewski's logic can be given a natural formal semantics which, unlike current versions, avoids commitment to abstract entities. Building on hints in Wittgenstein's Tractatus, I develop the idea of a way of meaning which is the basis for what I call combinatorial semantics. I then consider whether this commits us to abstract objects or an intensional metalogic.

  • Reism and Le'sniewski's Ontology.Jan Wole'nski - 1986 - History and Philosophy of Logic 7 (2):167-176.
    This paper examines relations between reism, the metaphysical theory invented by Tadeusz Kotarbi?ski, and Le?niewski's calculus of names. It is shown that Kotarbi?ski's interpretation of common nouns as genuine names, i.e. names of things is essentially based on Le?niewski's logical ideas. It is pointed out that Le?niewskian semantics offers better prospects for nominalism than does semantics of the standard firstorder predicate calculus.
