Prima Facie Obligation
This paper presents a nonmonotonic deontic logic based on commonsense entailment. It establishes criteria a successful account of obligation should satisfy, and develops a theory that satisfies them. The theory includes two conditional notions of prima facie obligation. One is constitutive; the other is epistemic, and follows nonmonotonically from the constitutive notion. The paper defines unco...
متن کاملThe PRIMA Fringe Sensor Unit
Context. The Fringe Sensor Unit (FSU) is the central element of the Phase Referenced Imaging and Micro-arcsecond Astrometry (PRIMA) dual-feed facility and provides fringe sensing for all observation modes, comprising off-axis fringe tracking, phase referenced imaging, and high-accuracy narrow-angle astrometry. It is installed at the Very Large Telescope Interferometer (VLTI) and successfully se...
متن کاملObject Orientation within the PRIMA-NDBS
1. Overview In the following we wish to highlight the design and implementation concepts of a non-standard database system (NDBS) called PRIMA and its provision for object orientation. Non-standard database applications such as CAD/CAM, VLSI design, and knowledge-based systems require adequate modeling facilities for their application objects for various reasons [H~.88b]. Data models dedicated ...
متن کاملThe Meaning of the Term "Prima Facie"
non-earthly matters are presumed invalid. In I Frederick Copleston, S.J., A History of Philosophy at pt. 4, 24-25 (1962), Father Copleston observes-with typical succinct brilliance-regarding the above passage from Aristotle: Thus if a patient who suffers from delirium tremens "sees" pink rats, the senses as such do not err; error arises when the patient judges that the pink rats are "out there,...
متن کاملAn Update Semantics for Prima Facie Obligations
The deontic logic dus is a deontic update semantics for prescriptive obligations based on the update semantics of Veltman. In dus the definition of logical validity of obligations is not based on static truth values but on dynamic action transitions. In this paper prescriptive prima facie obligations are formalized in update semantics. The logic formalizes the specificity principle, has reinsta...
