The health of newborns has always been subject to the natural lottery. When in the past a severely disabled baby was born, nature provided the “solution,” and the child did not survive. Medical technology has brought about a change; fetuses who would have died during pregnancy or newborns who once would have had little chance to survive are now kept alive. Although these technological advances do benefit many children, the dark side is that more severely handicapped babies are surviving.When a (...) severely disabled baby is born, all persons concerned are faced with emotional difficulties as well as moral and legal dilemmas. Questions that arise include whether it is acceptable, morally and legally, to allow the severely handicapped newborn to die by forgoing treatment or by direct intervention. (shrink)

The author joins the discussion on selection of patients in the face of life-saving resources initiated in the Journal by Parsons and Lock, Mooney and the editorial in the December 1980 issue. In this article several selection systems are discussed. The author is in favour of a `criteria-system'. The criteria for such a system are elaborated. On the basis of a sequence of values a sequence of criteria is proposed. Attention is also given to the procedural aspects.

Although AGM theory contraction (Alchourrón et al., 1985; Alchourrón and Makinson, 1985) occupies a central position in the literature on belief change, there is one aspect about it that has created a fair amount of controversy. It involves the inclusion of the postulate known as Recovery. As a result, a number of alternatives to AGM theory contraction have been proposed that do not always satisfy the Recovery postulate (Levi, 1991, 1998; Hansson and Olsson, 1995; Fermé, 1998; Fermé and Rodriguez, 1998; (...) Rott and Pagnucco, 1999). In this paper we present a new addition, systematic withdrawal, to the family of withdrawal operations, as they have become known. We define systematic withdrawal semantically, in terms of a set of preorders, and show that it can be characterised by a set of postulates. In a comparison of withdrawal operations we show that AGM contraction, systematic withdrawal and the severe withdrawal of Rott and Pagnucco (1999) are intimately connected by virtue of their definition in terms of sets of preorders. In a future paper it will be shown that this connection can be extended to include the epistemic entrenchment orderings of Gärdenfors (1988) and Gärdenfors and Makinson (1988) and the refined entrenchment orderings of Meyer et al. (2000). (shrink)
