With its revival in recent years, rhetoric has provided a special perspective for modern people. If we take rhetoric as a framework to rethink democracy and rule of law, we may not only grasp a new understanding of them, but also gain more knowledge of the possible role of rhetoric in the contemporary world. We will find that rhetoric was closely related to democracy and rule of law, and is still fully accordant with ideas of democracy and rule of law in modern society. Moreover, rhetoric can provide intellectual support to these concepts.
