231Rationality in Flux–Formal Representations of Methodological ChangeIn Erik J. Olson Sebastian Enqvist (ed.), Belief Revision meets Philosophy of Science, Springer. pp. 347--356. 2011.A central aim for philosophers of science has been to understand scientific theory change, or more specifically the rationality of theory change. Philosophers and historians of science have suggested that not only theories but also scientific methods and standards of rational inquiry have changed through the history of science. The topic here is methodological change, and what kind of theory of rational methodological change is appropriate. The modest ambition of this paper is to discuss in what…Read more

562Epistemic entrenchment with incomparabilities and relational belief revisionIn André Fuhrmann & Michael Morreau (eds.), The Logic of Theory Change: Workshop, Konstanz, FRG, October 13-15, 1989, Proceedings, Springer. pp. 93--126. 1991.In earlier papers (Lindström & Rabinowicz, 1989. 1990), we proposed a generalization of the AGM approach to belief revision. Our proposal was to view belief revision as a relation rather thanas a function on theories (or belief sets). The idea was to allow for there being several equally reasonable revisions of a theory with a given proposition. In the present paper, we show that the relational approach is the natural result of generalizing in a certain way an approach to belief revision due to…Read more

37Collected Papers of Stig Kanger with Essays on his Life and Work, Vol. I-IIKluwer Academic Publishers. 2001.Stig Kanger (1924--1988) made important contributions to logic and formal philosophy. 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. But he contributed significantly to action theory, preference logic and the theory of measurement as well. The first volume is a complete collection of Kanger's philosophical papers. The second volume contains critical essays on the various a…Read more

1088Horwich's minimalist conception of truth: some logical difficultiesLogic and Logical Philosophy 9 (n/a): 161-181. 2001.Aristotle’s words in the Metaphysics: “to say of what is that it is, or of what is not that it is not, is true” are often understood as indicating a correspondence view of truth: a statement is true if it corresponds to something in the world that makes it true. Aristotle’s words can also be interpreted in a deflationary, i.e., metaphysically less loaded, way. According to the latter view, the concept of truth is contained in platitudes like: ‘It is true that snow is white iff snow is white’, ‘I…Read more

47How to model relational belief revisionIn Dag Prawitz & Dag Westerståhl (eds.), Logic and Philosophy of Science in Uppsala: Papers From the 9th International Congress of Logic, Methodology and Philosophy of Science, Kluwer Academic Publishers. 1994.This is a short version of Lindström & Rabinowicz 1991.In earlier papers, we proposed a generalization of the AGM approach to belief revision. The proposal was to view belief revision as a relation rather than as a function on theories (or belief sets). Going relational means that one allows for several equally reasonable revisions of a theory with a given proposition. In the present paper, we show that the relational approach is the natural result of generalizing in a certain way an approach to…Read more

1041Quine's interpretation problem and the early development of possible worlds semanticsIn Ondrey Majer (ed.), The Logica Yearbook 2000, Filosofia. 2001.In this paper, I shall consider the challenge that Quine posed in 1947 to the advocates of quantified modal logic to provide an explanation, or interpretation, of modal notions that is intuitively clear, allows “quantifying in”, and does not presuppose, mysterious, intensional entities. The modal concepts that Quine and his contemporaries, e.g. Carnap and Ruth Barcan Marcus, were primarily concerned with in the 1940’s were the notions of (broadly) logical, or analytical, necessity and possibilit…Read more

247Føllesdal i UppsalaFilosofisk Tidskrift 8 (4). 1987.Årets Hägerströmföreläsningar i Uppsala gavs i februari av den norske filosofen Dagfinn Føllesdal. Ämnet var "Mening og Erfaring". Dagfinn Føllesdal doktorerade 1961 vid Harvard med Willard Van Quine som handledare på en avhandling om kvantifierad modallogik. Han blev internationellt känd främst för studier om Husserls fenomenologi och dess förhållande till Frege samt för sina arbeten om Quines språkfilosofi. Allt sedan 60-talet har Føllesdal delat sin tid mellan Oslouniversitetet och Stanfordun…Read more

It saw the development of three major foundational programmes: the logicism of Frege, Russell and Whitehead, the intuitionism of Brouwer, and Hilbert's formalist and proof-theoretic programme. In this period, there were als…Read more

316Critical Study: Jon Barwise & John Perry, Situations and Attitudes (review)Noûs (5): 743-770. 1991.The present essay is a critical study of Barwise and Perry’s book, emphasizing the logical and model-theoretical aspects of their work. I begin by presenting the authors’ criticism of the classical view of logic and semantics within the tradition of Frege, Russell and Tarski. In this connection, I discuss the so-called Frege argument (“the slingshot”). I try to show that the argument appears inconclusive, not only from a situation-theoretic perspective, but also from such alternative perspective…Read more
