His educational thoughts can be summarized as follows: making people understand the world of ideas and cultivating people's good ideas.

In Plato's educational ethics, natural morality is its theoretical basis. It is pointed out that people are born with the idea of goodness, the purpose and task of education is to guide people to know goodness through education, and the content of education is to make goodness more concrete. If Plato's educational ethics is a building, then natural morality is the basis of building a building. Education is a more effective way and means to promote the idea of goodness.

His ideological characteristics:

In Plato's thought, the visible "real world" is different from the abstract "ideal world", and the "real world" is only the shadow of the "ideal world", which shows that he thinks the ideal world is important.

He believes that people have acquired the knowledge of everything before they are born. When the soul is attached to the body, the existing knowledge is forgotten. Only by studying can we "recall" the forgotten knowledge and reach the ideal world. Learning is memory. This is his view of knowledge.
