85Providing foundations for coherentismErkenntnis 51 (2-3): 243-265. 1999.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 an…Read more

21Medical Ethics and New Public Management in SwedenCambridge Quarterly of Healthcare Ethics 23 (3): 261-267. 2014.In order to shorten queues to healthcare, the Swedish government has introduced a yearly “queue billion” that is paid out to the county councils in proportion to how successful they are in reducing queues. However, only the queues for first visits are covered. Evidence has accumulated that queues for return visits have become longer. This affects the chronically and severely ill. Swedish physicians, and the Swedish Medical Association, have strongly criticized the queue billion and have claimed …Read more

25Outcome level analysis of belief contractionReview of Symbolic Logic 6 (2): 183-204. 2013.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

28Mill’s Circle(s) of LibertySocial Theory and Practice 41 (4): 734-749. 2015.J.S. Mill’s advocacy of liberty was based only in part on his harm principle. He also endorsed two other principles that considerably extend the scope of liberty: first, a principle of individual liberty that is based on the value of positive freedom and of developing individuality, and second, a principle of free trade or economic freedom that is based on the value of economic efficiency. An analysis is offered of how these three principles are combined in Mill’s account of liberty and how they…Read more

58Preference-based deontic logic (PDL)Journal of Philosophical Logic 19 (1). 1990.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 lo…Read more

23Measuring UncertaintyStudia Logica 93 (1): 21-40. 2009.Two types of measures of probabilistic uncertainty are introduced and investigated. Dispersion measures report how diffused the agent’s second-order probability distribution is over the range of first-order probabilities. Robustness measures reflect the extent to which the agent’s assessment of the prior (objective) probability of an event is perturbed by information about whether or not the event actually took place. The properties of both types of measures are investigated. The most obvious ty…Read more

203Objective or subjective 'ought'?Utilitas 22 (1): 33-35. 2010.The prescriptive has both an objective and a subjective interpretation. In the objective sense, what one ought to do depends on what is actually true. In the subjective sense it depends on what one believes to be true. Ordinary usage seems to vacillate between these two interpretations. An example (the indecisive terrorist) is used to show that a subjective ought statement can have a determinate truth-value in situations where the corresponding objective ought statement has no truth-value, not e…Read more

125Philosophy and other disciplinesMetaphilosophy 39 (4-5): 472-483. 2008.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 missio…Read more

36Making Road Traffic Safer: Reply to OriPhilosophical Papers 43 (3): 365-375. 2014.In order to reduce the death toll of road traffic it is necessary to focus on how vehicles and roads can be improved. Like other dangerous machines, motor vehicles should be equipped with safety devices that prevent mistakes by the operator from leading to serious consequences. Speed limiters that prevent driving at illegal speeds would save many lives, and so would alcohol interlocks. Meshi Ori's proposal that most cars should be replaced by motorcycles would not lead to the moral improvement t…Read more

25Local ChangeStudia Logica 70 (1): 49-76. 2002.An agent can usually hold a very large number of beliefs. However, only a small part of these beliefs is used at a time. Efficient operations for belief change should affect the beliefs of the agent locally, that is, the changes should be performed only in the relevant part of the belief state. In this paper we define a local consequence operator that only considers the relevant part of a belief base. This operator is used to define local versions of the operations for belief change. Representat…Read more
