Tao is the highest category of Laozi’s thought, and Taoism is naturally the supreme law that all things follow. In order to reach the level of Tao, people need to remove their own desires and excessive desires, by making abstinence, ignorance and no desire. The desirelessness in Laozi’s thought is not to eliminate desires, but to make individual desires meet the requirements of the Tao and to fulfill the desire of nature. The desirelessness not only includes the moral cultivation orientation of the desire to control, but also the political ethical orientation of selflessness and indisputability. Laozi’s thoughtlessness has important theoretical and practical value for the current construction of a clean and honest culture.
