Schools came into being as early as the slave society, but the slave schools in China or Europe generally ignored intellectual education, and their main positions were (military) physical education and moral education. This is because the children of slave owners are educated in slave schools. They are the rulers of the future. Their task was to suppress and rule slaves, and they fought in the war between slave owners. Therefore, the main contents of education are physical education and moral education. That is to say, in the slave society, physical education and moral education are the center of school education, and intellectual education is placed in a secondary position.

Education in feudal society, like education in slavery society, does not attach importance to intellectual education. This is determined by some common points in their production methods and political culture; Production is dominated by manual labor, workers are surrounded by self-sufficient natural economy, science and technology are rarely used in production, and production develops slowly. Serfs are no longer the private property of landlords, but they still have no personal freedom, and the hierarchy has reached its peak. Even within the landlord class, they were ruled by harsh hierarchical autocracy. Therefore, apart from intellectual education, theology, superstition and cultural autocracy dominated feudal education in China and Europe, reaching an extreme level. Therefore, moral education, which embodies the ideological rule of feudal landlords, has become the center of school education in feudal society.
