Rousseau believes that the essence of education is to let a child learn to be a man first. In the process of a child's growth, he should learn equality, fraternity and freedom, develop both physically and mentally, not surpass or lag behind, and be able to master his own destiny and adapt to the changes in the external objective environment.

If you are a parent and take care of your children by yourself, you will find that some children are naturally quiet, can sleep and don't like crying. They are all good babies to take care of. Some children are naturally noisy and sleep less. Some children are witty, some love painting, some love listening to music, some love sports, some are naturally bold, and some are timid and afraid of heights.

Children have their own unique thoughts and behaviors from birth, and everyone is so different. The task of our parents or adults is to discover the child's nature, conform to the child's nature, and create an environment for the child to grow into a free man who develops according to his own nature.

This is the essence of educating children, letting them be free and developing according to their own nature. This is what Rousseau called nature education, which is the best education for children.
