Abstract: This essay is about a theory of belief and a theory of belief reports formulated within the framework of DR (Discourse Representation) theory.1 DR theory's treatment of definite and indefinite noun phrases leads to a superior treatment of belief reports involving singular terms. But it also provides something of even greater potential benefit to a treatment of belief: a (highly idealized) theory of how recipients recover verbally encoded information and of what form such informa-

TL;DR: A model of belief updating and belief revision motivated by concerns about the logic of belief and belief reports, which is much more complex than that presupposed in the classical theory of belief revision such as propounded by Alchourron, Makinson and Gardenfors.
Abstract: I have sketched a model of belief updating and belief revision motivated by concerns about the logic of belief and belief reports. In this model beliefs are assumed to have a complex structure and to be related together within the cognitive state in quite intricate ways. The structure is built up modified during belief updating and during revision. The model of beliefs is much more complex than that presupposed in the classical theory of belief revision such as propounded by Alchourron, Makinson and Gardenfors. Nevertheless, at least some of the developments of the classical theory may be carried over to this more complex model.
