The central issue of this paper is the semantics of the modal propositions, with emphasis on the necessary and permanent propositions. First, the writer offers a short explanation of the modal propositions according to the traditional logic, then describes their temporal analysis, and finally, criticizes such an interpretation. However, the whole perspective of the paper is not merely negative, and the writer tries to reread and recognize the traditional views and comments on the semantics of the modal propositions.
