Stig Kanger made important contributions to logic and formal philosophy. Kanger's dissertation Provability in Logic, 1957, contained significant results in proof theory as well as the first fully worked out model-theoretic interpretation of quantified modal logic. It is generally accepted nowadays that Kanger was one of the originators of possible worlds semantics for modal logic. Kanger's most original achievements were in the areas of general proof theory, the semantics of modal and deontic logic, and the logical (...) analysis of the concept of rights. He also contributed to action theory, preference logic, and the theory of measurement. This is the first of two volumes dedicated to the work of Stig Kanger. The present volume is a complete collection of Kanger's philosophical papers. The second volume contains critical essays on Kanger's work, as well as biographical essays on Kanger written by colleagues and friends. (shrink)

Basin-Matthews-Viganò approach to construction of labelled deduction systems for normal modal logics is adapted to „Fitch proof-format“, and it is applied to the language of deontic-praxeological logic. Segerberg's suggestion on how to asses the adequacy of a logic for Kanger's theory of rights is being formally explicated and it is proved that herewith proposed system of labelled deduction satisfies Segerberg's criteria of adequacy. For the purpose of building the proof a semantics is given, which connects „the simplest semantics of (...) action“ with standard semantics of deontic logic. Soundness and completeness of the proposed labelled deduction with respect to aforementioned semantics is proved. (shrink)

This paper traces the intellectual effects of an encounter between Stig Kanger and Donald Davidson -two very different philosophers working in two seemingly unconnected areas. Their meeting in Oslo 1979 led the latter to improve his influential theory of radical interpretation and gave the former an inspiration for a rather striking paradox in preference logic. But, as we show, the paradox can be dis-solved and the radical interpretation continues to confront serious difficulties. Simultaneous elicitation of a speaker’s meaning, beliefs (...) and desires merely from his attitudes to sentences in the language he uses is a very ambitious project, but its theoretic viability is strongly questionable.

Despite decades of development, Actor-Network Theory continues to be characterized by a good deal of ambiguities and internal tensions. This situation has led to a suggestion that instead of one ANT it may be meaningful to speak of ‘the ANT multiple’. Following this line of reasoning, this article aims to create a map of the variety of positions riding under the ANT banner. Based on an in-depth reading of ANT literature, seven different interpretations of ANT are identified and subjected to (...) critical analysis while accommodating for the concerns of ANT proponents about the way ANT has been previously criticized. The results of the analysis serve to increase the reflexivity of both sides of the debate about their underlying assumptions, and provide suggestions how ANT could be employed, developed and criticized more productively in the future.
