    Crop Biotechnology for the Environment?
    with Karin Joelsson
    Journal of Agricultural and Environmental Ethics 26 (4): 759-770. 2013.
    In public debates, agricultural biotechnology is almost invariably discussed as a potential threat to the environment and to human health. Without downplaying the risks associated with this technology we emphasize that if properly regulated, it can be a forceful tool to solve environmental problems and promote human health. Agricultural biotechnology can reduce environmental problems in at least three ways: it can diminish the need for environmentally damaging agricultural practices such as pest…Read more
  • A Note On Anti-cyclic Properties Of Complete Binary Relations
    Reports on Mathematical Logic 41-44. 1993.
    A simplified notation is introduced for transitivity and related properties of binary relations. Interrelations of such properties can be proved in a facilitated way with manipulation-rules that the new notation makes possible.

    Belief contraction without recovery
    Studia Logica 50 (2). 1991.
    The postulate of recovery is commonly regarded to be the intuitively least compelling of the six basic Gärdenfors postulates for belief contraction. We replace recovery by the seemingly much weaker postulate of core-retainment, which ensures that if x is excluded from K when p is contracted, then x plays some role for the fact that K implies p. Surprisingly enough, core-retainment together with four of the other Gärdenfors postulates implies recovery for logically closed belief sets. Reasonable …Read more

    A possible world semantics for preference is developed. The remainder operator () is used to give precision to the notion that two states of the world are as similar as possible, given a specified difference between them. A general structure is introduced for preference relations between states of affairs, and three types of such preference relations are defined. It is argued that one of them, actual preference, corresponds closely to the concept of preference in informal discourse. Its logical …Read more

    Blockage Revision
    Journal of Logic, Language and Information 25 (1): 37-50. 2016.
    Blockage revision is a version of descriptor revision, i.e. belief change in which a belief set K is changed with inputs whose success conditions are metalinguistic expressions containing the belief predicate \. This is a highly general framework that allows a single revision operator \ to take inputs corresponding to sentential revision ), contraction ) as well as more complex and composite operations. In blockage revision, such an operation is based on a relation \ of blockage among the set of…Read more

    Bootstrap Contraction
    Studia Logica 101 (5): 1013-1029. 2013.
    We can often specify how we would contract by a certain sentence by saying that this contraction would coincide with some other contraction that we know how to perform. We can for instance clarify that our contraction by p&q would coincide with our contraction by p, or by q, or by {p, q}. In a framework where the set of potential outcomes is known, some contractions are “self-evident” in the sense that there is only one serious candidate that can be the outcome of such a contraction. Contraction…Read more

    Som de första vetenskapliga tidskrifterna brukar man räkna den franska Journal des Sça- vants och den engelska Philosophical Transactions, som båda började ges ut år 1665. Redan under dessa tidskrifters första årtionden skaffade sig redaktörerna vanan att ta hjälp av experter inom olika områden med att granska manuskript. Detta system har sedan dess kommit att utvecklas och systematiseras, och kallas med en svåröversättlig engelsk term ”peer review”. Termen anger att manuskripten granskas av exp…Read more

    Coherentist Contraction
    Journal of Philosophical Logic 29 (3). 2000.
    A model of coherentist belief contraction is constructed. The outcome of belief contraction is required to be one of the coherent subsets of the original belief set, and a set of plausible properties is proposed for this set of coherent subsets. The contraction operators obtained in this way are shown to coincide with well-known belief base operations. This connection between coherentist and "foundationalist" approaches to belief change has important implications for the philosophical interpreta…Read more

    This paper summarizes and systematizes recent and ongoing work on non-prioritized belief change, i.e., belief revision in which the new information has no special priority due to its novelty.
