Summary:<jats:title>Abstract</jats:title><jats:p>A vast and interesting family of natural semantics lor belief revision is defined. Suppose one is given a distance <jats:italic>d</jats:italic> between any two models. One may then define the revision of a theory <jats:italic>K</jats:italic> by a formula <jats:italic>α</jats:italic> as the theory defined by the set of all those models of <jats:italic>α</jats:italic> that are closest, by <jats:italic>d</jats:italic>. to the set of models of <jats:italic>K</jats:italic>. This family is characterized by a set of rationality postulates that extends the AGM postulates. The new postulates describe properties of iterated revisions.</jats:p>
