Naturalism education theory is the main body of Rousseau's educational thought. Amir, published in 1762, embodies this idea. Goethe called this book the natural welfare of education, Kant forgot the habit of walking regularly for more than ten years because he read Emile, and Schiller called Rousseau the new Socrates, which was created by Jesus.

Rousseau believes that human education has three sources:

That is, "nature", "thing" and "man-made", only a good combination of the three kinds of education can achieve the expected goal. The ultimate goal of nature education is "natural person". A natural person is not a degenerate who returns to the primitive society, but a natural person who lives in the society, that is, a new person with good physical and mental health, sound mind and strong ability.

A necessary premise of Rousseau's nature education is to change children's views. People should not treat children as disciplined slaves, nor as shrinking adults, but as adults and children.
