Though it is intuitively plausible, Kripke’s theory of proper name and modality can not deal with the problem of cognitive significance of identity and the problem of reference within belief context, whereas the predication theory can do. This paper tries to ague that Kripke fails to blame the problem of reference within belief context on the nature of belief, so it is his account of reference that needs reconstruction. For the theory of Searle’s predication, the knowledge which is necessary to fix reference is none but contextual knowledge. By focusing on the relationship between reference and context, and on the basis of concept of behavior of reference and statements, the paper lays the foundation for a unified theory of reference.
