Abstract: An effective research paradigm must be a unity of aims, questions and methods. Hence, if “rhetoric” is redefined as “all processes of using language to realize one’s own purposes”, then the “ultimate target of rhetoric” shall be set as “effectively promoting the socialization of individuals, the interaction within groups and the modernization of social life by analyzing speech act”. The key issue of rhetoric is as follows: How can we modernize the linguistic communication among people, organizations, and between people and organizations in modern life? In order to solve this key issue, we find the most effective core concept is (new) speech act. Consequently come relative instrumental categories such as “subject type”, “purpose structure”, “discourse process”, “context parameter”, “media”, “interrelationship”, “behavior type”, “case analysis” and “system of rules (constitutive rules/strategic rules)”; in addition, it becomes possible to theoretically put forward a series of new questions such as “how to develop rhetoric of case database”. This constitutes the rhetoric based on “new speech act analysis”.
