A highly credible and convincing system of discourse, one which is able to articulate core values, must be supported by logical thought and scientific methods of demonstration that have evident national characteristics. This paper holds that the logical soul of the discourse system of Chinese civilization is Mohist logic. Syntactically, Mohist three-phase logic (causes, reasons, and classes) is the mode of reasoning for the discourse system of Chinese civilization; semantically, the Mohist distinguishing between right and wrong, that is, selecting the proper and striving for the right, creates the unity of analytical reason and dialectical reason in this discourse system; and pragmatically, the Mohist idea of being neither one-sided nor partial serves as the applied logic of the system, one that is remarkable for its qualities of political ethics.
