Summary:Abstract: "Circumscription proposed by McCarthy is one of the most hopeful formalizations of nonmonotonic aspects of commonsense reasoning. It has several versions, however, they are all proposed for denotative minimization of predicates, that is, circumscription minimizes the extension of predicates. Regarding such treatment, this paper considers three problems; absence of abnormal things, a limitation on equality and formalization of the unique name assumption. This paper proposes a solution for them by presenting a connotative treatment of circumscription. This treatment is based on the idea of circumscribing predicates connotatively, that is, minimizing the set of names denoting objects which satisfy a certain predicate."
