The Daoist/Taoist school of educational thought emphasized living in harmony with nature. Education aimed to teach people to maintain nature's way rather than try to change it. Students were taught to be content and refrain from desires, serving without pay. Education involved no textbooks, just allowing people to learn in a primitive, natural state. The Daoist philosophy was based on the theory that human nature is simply a state of nature that should be uninfluenced by cognition or desires.
