If you study, you worry that you won't find the problem. Only by studying with questions can we make progress.

This sentence comes from Southern Song philosophers Lu Jiuyuan and Old Master Q Q.

There are famous sayings with the same meaning as this sentence, such as "When you learn, it is more important to be suspicious", "A book without complete faith is better than no book", "Apply what you have learned", "Learn to solve doubts" and "Small doubts make small progress, while big doubts make great progress".

The main influence of Lu Jiuyuan:

In the eleventh year of Xichun (1 184), Lu Jiuyuan presented five essays when he met Xiaozong, which reflected his political thoughts: the monarch and the minister should treat each other honestly and get along without doubt; Regard "Tao" as the core of governing the country and restore the ancient political ideal of "ruling by three generations"; As well as the way to know people, the way to choose people and the law, all reflect his understanding of the situation at that time and his political views.

In Lu Jiuyuan's thought, "the rule of three generations" in ancient Xia, Shang and Zhou dynasties is the goal and ideal of human politics. In his eyes, the "three generations" are a beautiful era in which the belief and morality of the Grand Duke prevail: everyone knows propriety and justice, the world is public, and everyone is ashamed of selfishness, and the society is stable and harmonious; The king takes it as his duty to restore man's natural conscience and safeguard the way of propriety and righteousness.

In political thought, Lu Jiuyuan inherited the pre-Qin "people-oriented" thought and adhered to the political thought of "people are the foundation of the country". "Man" has played a fundamental role in political activities, which is not only the cornerstone of the country, but also the service object of the country. And "Jun" only plays the role of governing the country.
