Jia Yi's Academic Thought

Shi Renyi mainly serves the people. For the governors who were in power at that time and could resist the central authorities at any time, it was not enough to rely solely on benevolence and righteousness. They must also rely on a strong legal system, which makes them kind and generous. Power and the rule of law, this man is also an axe. The situation is settled and the strength is sufficient. It is based on benevolence and goodness, so it is ze, so Debu is ambitious in the world.

Jia Yi believes that Yin and Yang, heaven and earth, people and everything are born of virtue, while virtue is born of Tao. Tao is the ultimate source of all things in the universe, while virtue is the direct source of all things in the universe. Six principles of virtue: Tao, virtue, nature, spirit, knowledge and life; Virtue has six beauties: Tao, benevolence, righteousness, loyalty, faithfulness and concealment.

Jia Yi believes that the main content of benevolent government is to love the people. "If you love people, you will be attached to them." Only by benefiting the people and making money with them can you win their support. The basic content of Jia Yi's political thought is the benevolent political thought of loving the people.
