    Orthographic consistency and parafoveal preview benefit: A resource-sharing account of language differences in processing of phonological and semantic codes.Jochen Laubrock & Sven Hohenstein - 2012 - Behavioral and Brain Sciences 35 (5):292-293.
    Parafoveal preview benefit is an implicit measure of lexical activation in reading. PB has been demonstrated for orthographic and phonological but not for semantically related information in English. In contrast, semantic PB is obtained in German and Chinese. We propose that these language differences reveal differential resource demands and timing of phonological and semantic decoding in different orthographic systems.

  2. Ethical criteria of risk acceptance.Sven Ove Hansson - 2003 - Erkenntnis 59 (3):291 - 309.
    Mainstream moral theories deal with situations in which the outcome of each possible action is well-determined and knowable. In order to make ethics relevant for problems of risk and uncertainty, moral theories have to be extended so that they cover actions whose outcomes are not determinable beforehand. One approach to this extension problem is to develop methods for appraising probabilistic combinations of outcomes. This approach is investigated and shown not to solve the problem. An alternative approach is then developed. Its (...)

  4. Cutting the Gordian Knot of Demarcation.Sven Ove Hansson - 2009 - International Studies in the Philosophy of Science 23 (3):237-243.
    A definition of pseudoscience is proposed, according to which a statement is pseudoscientific if and only if it (1) pertains to an issue within the domains of science, (2) is not epistemically warranted, and (3) is part of a doctrine whose major proponents try to create the impression that it is epistemically warranted. This approach has the advantage of separating the definition of pseudoscience from the justification of the claim that science represents the most epistemically warranted statements. The definition is (...)

    Descriptor Revision.Sven Ove Hansson - 2014 - Studia Logica 102 (5):955-980.
    A descriptor is a set of sentences that are truth-functional combinations of expressions of the form \ , where \ is a metalinguistic belief predicate and p a sentence in the object language in which beliefs are expressed. Descriptor revision ) is an operation of belief change that takes us from a belief set K to a new belief set \ where \ is a descriptor representing the success condition. Previously studied operations of belief change are special cases of descriptor (...)

    Credibility limited revision.Sven Ove Hansson, Eduardo Leopoldo Fermé, John Cantwell & Marcelo Alejandro Falappa - 2001 - Journal of Symbolic Logic 66 (4):1581-1596.
    Five types of constructions are introduced for non-prioritized belief revision, i.e., belief revision in which the input sentence is not always accepted. These constructions include generalizations of entrenchment-based and sphere-based revision. Axiomatic characterizations are provided, and close interconnections are shown to hold between the different constructions.

    European public advice on nanobiotechnology—four convergence seminars.Marion Godman & Sven Ove Hansson - 2009 - NanoEthics 3 (1):43-59.
    In order to explore public views on nanobiotechnology (NBT), convergence seminars were held in four places in Europe; namely in Visby (Sweden), Sheffield (UK), Lublin (Poland), and Porto (Portugal). A convergence seminar is a new form of public participatory activity that can be used to deal systematically with the uncertainty associated for instance with the development of an emerging technology like nanobiotechnology. In its first phase, the participants are divided into three “scenario groups” that discuss different future scenarios. In the (...)

    Changes of disjunctively closed bases.Sven Ove Hansson - 1993 - Journal of Logic, Language and Information 2 (4):255-284.
    An operator of contraction for a belief set (a theory) can be obtained by assigning to it a belief base and an operator of partial meet contraction for that base. It is argued that closure of the base under disjunction is an intuitively reasonable condition. Axiomatic characterizations are given of the contractions of belief sets that can be generated by (various types of) partial meet contraction on disjunctively closed bases. The corresponding revision operators are also characterized. Finally, some results are (...)

    Providing foundations for coherentism.Sven Ove Hansson & Erik J. Olsson - 1999 - Erkenntnis 51 (2-3):243-265.
    We prove that four theses commonly associated with coherentism are incompatible with the representation of a belief state as a logically closed set of sentences. The result is applied to the conventional coherence interpretation of the AGM theory of belief revision, which appears not to be tenable. Our argument also counts against the coherentistic acceptability of a certain form of propositional holism. We argue that the problems arise as an effect of ignoring the distinction between derived and non-derived beliefs, and (...)

    Preference-based deontic logic (PDL).Sven Ove Hansson - 1990 - Journal of Philosophical Logic 19 (1):75 - 93.
    A new possible world semantics for deontic logic is proposed. Its intuitive basis is that prohibitive predicates (such as "wrong" and "prohibited") have the property of negativity, i.e. that what is worse than something wrong is itself wrong. The logic of prohibitive predicates is built on this property and on preference logic. Prescriptive predicates are defined in terms of prohibitive predicates, according to the wellknown formula "ought" = "wrong that not". In this preference-based deontic logic (PDL), those theorems that give (...)

    Coping with the Unpredictable Effects of Future Technologies.Sven Ove Hansson - 2011 - Philosophy and Technology 24 (2):137-149.
    Available methods such as technology assessment and risk analysis have failed to predict the effects of technological choices. We need to give up the futile predictive ambitions of previous approaches and instead base decisions on systematic studies of alternative future developments. It will then be necessary to cope with mere possibility arguments, i.e., arguments in which a conclusion is drawn from a mere possibility that a course of action may have certain consequences. A five-step procedure is proposed for the assessment (...)

    Outcome level analysis of belief contraction.Sven Ove Hansson - 2013 - Review of Symbolic Logic 6 (2):183-204.
    The outcome set of a belief change operator is the set of outcomes that can be obtained with it. Axiomatic characterizations are reported for the outcome sets of the standard AGM contraction operators and eight types of base-generated contraction. These results throw new light on the properties of some of these operators.

  16. Philosophy and other disciplines.Sven Ove Hansson - 2008 - Metaphilosophy 39 (4-5):472-483.
    Abstract: This article offers a perspective on the role of philosophy in relation to other academic disciplines and to society in general. Among the issues treated are the delimitation of philosophy, whether it is a science, its role in the community of knowledge disciplines, its losses of subject matter to other disciplines, how it is influenced by social changes and by progress in other disciplines, and its role in interdisciplinary work. It is concluded that philosophy has an important mission in (...)

    Safe Contraction Revisited.Hans Rott & Sven Ove Hansson - 2014 - In Sven Ove Hansson (ed.), David Makinson on Classical Methods for Non-Classical Problems (Outstanding Contributions to Logic, Vol. 3). Springer. pp. 35–70.
    Modern belief revision theory is based to a large extent on partial meet contraction that was introduced in the seminal article by Carlos Alchourrón, Peter Gärdenfors, and David Makinson that appeared in 1985. In the same year, Alchourrón and Makinson published a significantly different approach to the same problem, called safe contraction. Since then, safe contraction has received much less attention than partial meet contraction. The present paper summarizes the current state of knowledge on safe contraction, provides some new results (...)

  19. Ethics and radiation protection.Sven Ore Hansson - manuscript
    Some of the major problems in radiation protection are closely connected to issues that have a long, independent tradition in moral philosophy. This contribution focuses on two of these issues. One is the relationship between the protection of individuals and optimisation on the collective level, and the other is the relative valuation of future versus immediate damage. Some of the intellectual tools that have been developed by philosophers can be useful in radiation protection. On the other hand, philosophers have much (...)

    Do we need second-order probabilities?Sven Ove Hansson - 2008 - Dialectica 62 (4):525-533.
    Although it has often been claimed that all the information contained in second-order probabilities can be contained in first-order probabilities, no practical recipe for the elimination of second-order probabilities without loss of information seems to have been presented. Here, such an elimination method is introduced for repeatable events. However, its application comes at the price of losses in cognitive realism. In spite of their technical eliminability, second-order probabilities are useful because they can provide models of important features of the world (...)

    Maximal and perimaximal contraction.Sven Ove Hansson - 2013 - Synthese 190 (16):3325-3348.
    Generalizations of partial meet contraction are introduced that start out from the observation that only some of the logically closed subsets of the original belief set are at all viable as contraction outcomes. Belief contraction should proceed by selection among these viable options. Several contraction operators that are based on such selection mechanisms are introduced and then axiomatically characterized. These constructions are more general than the belief base approach. It is shown that partial meet contraction is exactly characterized by adding (...)

    Do we Need a Special Ethics for Research?Sven Ove Hansson - 2011 - Science and Engineering Ethics 17 (1):21-29.
    Research is subject to more stringent ethical requirements than most other human activities, and a procedure that is otherwise allowed may be forbidden in research. Hence, risk-taking is more restricted in scientific research than in most non-research contexts, and privacy is better protected in scientific questionnaires than in marketing surveys. Potential arguments for this difference are scrutinized. The case in its favour appears to be weak. A stronger case can be made in favour of a difference in the opposite direction: (...)

  24. Economic (ir)rationality in risk analysis.Sven Ove Hansson - 2006 - Economics and Philosophy 22 (2):231-241.
    Mainstream risk analysis deviates in at least two important respects from the rationality ideal of mainstream economics. First, expected utility maximization is not applied in a consistent way. It is applied to endodoxastic uncertainty, i.e. the uncertainty (or risk) expressed in a risk assessment, but in many cases not to metadoxastic uncertainty, i.e. uncertainty about which of several competing assessments is correct. Instead, a common approach to metadoxastic uncertainty is to only take the most plausible assessment into account. This will (...)

    Coherentist Contraction.Sven Ove Hansson - 2000 - Journal of Philosophical Logic 29 (3):315 - 330.
    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 interpretation of models of belief change.

    Se resumen las ventajas y desventajas de la formalización en filosofía. Se concluye que la filosofía formalizada es una especialidad en peligro que necesita ser revitalizada, y que debe incrementar sus interacciones con la filosofía no formalizada. El estilo enigmático, que es común en la lógica filosófica, debe llevar a discusiones explícitas sobre la relación problemática entre modelos formales, conceptos filosóficos y temas que motiven su desarrollo.

    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 pesticides, fertilizers, tillage, and irrigation. It can reduce the land (...)
