“…8 Definition 15 A formula p is valid in a belief revision system K = K, * ⇐⇒ all theories T ∈ K entail p. Now we are ready to establish which conditional axioms exactly characterize Pareto-minimal theory change. (Arló-Costa, 1990). The source of the problem is that K*2 requires a revision of the inconsistent theory to be consistent.…”

Summary.A rational agent changes her beliefs in response to new information; a widely held idea is that such belief changes should be minimal. This paper is an overview of the theory of minimal belief revision. I employ a decisiontheoretic framework to compare various principles for minimal belief revision. Belief revisionBelief change pervades human life. As we interact with our environment, we continually update our beliefs about it. In such situations, we encounter the problem of how should an agent change his beliefs in light of new information. In the last three decades or so, logicians, philosophers and computer scientists have developed answers to this question under the heading of "belief revision theory". Two main features characterize belief revision theory: the formal model I am grateful to Mamoru Kaneko for detailed comments on drafts of this paper, and to Hans Rott for helping me draw on his work on belief revision.
