The so-called "fearlessness of destiny" means breaking the superstition of "celestial phenomena" and no longer analogizing social order with the constancy of natural laws.
The Analects of Confucius by Ji Shi says, "A gentleman has three fears." The first one is "fear of destiny." It should be a reference. The "mandate of heaven" here is traditionally believed to refer to "the destiny of heaven, which is good and bad but good or bad" (He Yan's "Collected Notes"), that is, the number of days.
There is no fear of destiny, no law of ancestors, and no sympathy for human words. From "History of the Song Dynasty: Biography of Wang Anshi". In 1058 AD, Wang Anshi wrote to Song Renzong, requesting a comprehensive reform of the laws since the early Song Dynasty. The famous "Wang Anshi's Reform" reversed the state of poverty and weakness since the early Song Dynasty, and Wang Anshi's famous saying has been passed down to this day. The so-called "fear of destiny" means breaking the superstition of "celestial phenomena" and no longer relying on the constant laws of nature. To draw an analogy to social order.
The so-called "ancestors are not enough" means to find new impetus for social development from the historical experience of our predecessors, rather than completely adhering to and maintaining it; the so-called "people's words are not enough" is a statement. The determination and courage of this kind of innovation are not shaken by various rumors.
