In this review, the first twentyfive years of this development are summarized. The topics covered include equivalent characterizations of AGM operations, extended represe…Read more

41European public advice on nanobiotechnology—four convergence seminarsNanoEthics 3 (1): 43-59. 2009.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…Read more

25Should Probabilistic Design Replace Safety Factors?Philosophy and Technology 24 (2): 151-168. 2011.Safety is a concern in almost all branches of engineering. Whereas safety was traditionally introduced by applying safety factors or margins to the calculated maximum load, this approach is increasingly replaced with probabilistic risk assessment (PRA) as a tool for dimensioning safety measures. In this paper, the two approaches are compared in terms of what they aim at and what they can, in fact, achieve. The outcome of this comparison suggests that the two approaches should be seen as compleme…Read more

108Selective revisionStudia Logica 63 (3): 331-342. 1999.We introduce a constructive model of selective belief revision in which it is possible to accept only a part of the input information. A selective revision operator ο is defined by the equality K ο α = K * f(α), where * is an AGM revision operator and f a function, typically with the property ⊢ α → f(α). Axiomatic characterizations are provided for three variants of selective revision.

16A Monoselective Presentation of AGM RevisionStudia Logica 103 (5): 1019-1033. 2015.A new equivalent presentation of AGM revision is introduced, in which a preference-based choice function directly selects one among the potential outcomes of the operation. This model differs from the usual presentations of AGM revision in which the choice function instead delivers a collection of sets whose intersection is the outcome. The new presentation confirms the versatility of AGM revision, but it also lends credibility to the more general model of direct choice among outcomes of which A…Read more

654Epistemic Paternalism in Public HealthJournal of Medical Ethics 31 (11): 648-653. 2005.Receiving information about threats to one’s health can contribute to anxiety and depression. In contemporary medical ethics there is considerable consensus that patient autonomy, or the patient’s right to know, in most cases outweighs these negative effects of information. Worry about the detrimental effects of information has, however, been voiced in relation to public health more generally. In particular, information about uncertain threats to public health, from—for example, chemicals—are sa…Read more

54A formal representation of declaration-related legal relationsLaw and Philosophy 9 (4). 1990.A formal language is introduced that contains expressions for the dependency of a legal relation on the claims that the concerned individuals make and on the permissions that they grant. It is used for a classification of legal relations into six major categories: categorical obligation, categorical permission, claimable obligation, grantable permission, claim-dependent obligation and grant-dependent permission. Legal rights may belong to any of these six categories, but the characteristics of a…Read more

22A new representation theorem for contranegative deontic logicStudia Logica 77 (1). 2004.The logic of an ought operator O is contranegative with respect to an underlying preference relation if it satisfies the property Op & (¬p)(¬q) Oq. Here the condition that is interpolative ((p (pq) q) (q (pq) p)) is shown to be necessary and sufficient for all -contranegative preference relations to satisfy the plausible deontic postulates agglomeration (Op & OqO(p&q)) and disjunctive division (O(p&q) Op Oq).
