This paper presents a general, consistency-based framework for expressing belief change. The framework has good formal properties while being well-suited for implementation. Contraction is similarly defined although, interestingly, it is not interdefinable with revision.
The framework is general and flexible. For example, one could go on and express other belief change operations such as update and erasure, and the merging of knowledge bases. Further, the framework allows the incorporation of static and dynamic integrity constraints. The approach takes seriously the warning: Develops a concept of revision, akin in spirit to AGM partial meet revision, but in which the postulate of 'success' may fail.
Probabilistic Belief Revision via Similarity of Worlds Modulo Evidence
The basic idea is to see such an operation as composite, with a pre-processor using a priori considerations to resolve the question of whether to revise, following which another operation revises in a manner that protects the a priori material. Explores the effect of adding to the rules of preferential inference a number of non-Horn rules stronger than or incomparable with rational monotony, but still weaker than plain monotony or, in some cases, than conditional excluded middle , focussing on their representation in terms of special classes of preferential models.
Also considers some curious Horn rules beyond those of preferential inference but weaker than monotony.
Dalla Chiara et al eds Dordrecht: Investigates the logic of applying normative rules, and in particular those applications that are 'restrained', carried through as fully as is compatible with avoidance of contradictions or other consequences specified as undesirable. Such a separation provides a particularly elegant proof of Arrow's result, via a new 'splitting theorem'.
An extended review of what is known about the formal behaviour of nonmonotonic inference operations, including those generated by the principal systems in the artificial intelligence literature. Directed towards computer scientists and others with some background in logic. Completed towards the end of , this monograph was already widely cited in the literature before its publication early in , and has become a standard reference.

Counterbalancing some well-known negative observations, we show that there is also a strong positive answer. Shows how nonmonotonic inference relations may be generated in natural ways from sets of expected propositions, and also from relations of expectation between propositions.
Adapts to the context of nonmonotonic reasoning ideas developed by the authors for the logic of theory change references 23 and 29 below. Students from the entire continents have written articles to have fun the 70th birthday of Jan Srzednicki, a philosopher nonetheless on the peak of his powers. Srzednicki's clinical paintings alternates among difficulties of Austrian and German philosophy and questions of political philosophy.
The papers released during this quantity speak about subject matters of basic philosophy, within the transparent and deep sort either one of Srzednicki's personal philosophical paintings and of the authors investigated in his writings mainly Brentano and the Polish culture of analytic philosophy.

Philosophical Foundations of Quality of Life: After distinguishing issues that experience worth from the worth that issues may need, it describes the rules of a practical thought of worth. The e-book touches on common sense, Argumentation, and Debate, that are issues that would be explored intimately in Volumes 2 and three. Shielded Contraction. Contributed Papers.
