A: In the feudal society of Europe, religion became the spiritual pillar of the feudal system and a tool for ruling the people. Monks monopolized culture and school education, and science became a slave to religion. Within the feudal ruling class, there are two classes: monks and secular feudal lords (nobles), so there are two kinds of education: church education and knight education. The education of monks and feudal lords was carried out through missionary schools. To cultivate priests who are devout to God, obey religious authority and political power, and engage in religious activities, their educational contents are three subjects (grammar, rhetoric, dialectics) and four studies (arithmetic, geometry, astronomy, music), which are collectively called "seven arts", and all subjects are permeated with theological spirit (theology is the "crown" of all disciplines). The education of secular feudal lords is to train their children into brave knights through court education. The content of its education is the "seven skills of knight" (riding a horse, swimming, throwing a gun, fencing, hunting, playing chess and reciting poems), and of course it is also necessary to educate religious views and the moral quality of samurai. These two kinds of education are basically divorced from productive labor, and both are to maintain feudal serfdom. The children of working people can not only enter the parish school of the church, receive religious education and learn simple reading, writing and calculation, but also.
