"Conscience" is the true state of noumenon, the highest sense of kindness, and it is unexperienced and unexperienced. Why does Yangming need an extremely "conscience"? In Biography: "Every child loves his relatives and respects his brother, but this agility is not covered by selfish desires, but its essence." On the other hand, children's conscience cannot be fully revealed, because selfish desires cover up their conscience. Although conscience has an absolute judgment on good and evil from the perspective of ontology, people are living in an empirical life after all, and their judgment is full of experience. In an empirical society, people must establish a relationship with things. People's pursuit of things is constantly expanding, and their selfish desires are infinitely expanding. The judgment of good and evil cannot be based on conscience, so that what they do often runs counter to their conscience, which is blinded by selfish desires. Therefore, as the subject itself, we should strive to overcome our own selfish desires and be conscious of our own conscience in our daily life. The effective way to achieve the ultimate conscience is that the subject can always examine self-denial, always mention tearing and always guard against fear, can realize the highest meaning input of ethics and law, really cut into his own conscience, and finally make conscience return to the dominant position, standardize people's hearts, restrain behavior, restore light, crystal clear and reflect everything.
