In Rousseau's view, the most important natural right of mankind is freedom. Therefore, an education that conforms to nature must be a free education. This kind of education must protect children's kind nature and let them develop freely physically and mentally. Rousseau resolutely opposes the suppression of children's personality and the bondage of children's freedom, and opposes strict discipline and rote learning; We advocate that children be completely free to move, and give them as many opportunities as possible to move freely, so that they can see, think and feel everything in their own way. The task of educators is to create a suitable environment that can promote children's free development, observe carefully and induce them appropriately, and give them appropriate help when they feel lack of experience or strength, instead of forcing children to accept the unique ways and methods of adults. Rousseau believes that only those who develop freely according to children's nature can become truly free people. This view has the progressive significance of emancipating the mind and breaking the lifeless education situation, which is conducive to giving play to children's initiative and cultivating their ability of independent activities. Rousseau, on the other hand, overemphasized children's free activities and neglected the active guiding role of teachers, which is not desirable.
