Abstract

It is widely acknowledged that belief revision and belief update are two very different types of processes – one is appropriate to model belief change in a static environment, the other in a dynamic environment. Technically speaking, the former is constructed with the aid of a global preference ordering over possible worlds as the selection mechanism, and the latter with the aid of a family of such local orderings. It has been argued that update can be defined via revision. In this paper I argue that indeed revision can be defined via update in a restricted sense if a distance function is used as the selection mechanism.
