As a famous German philosopher, poet and playwright in the18th century, Schiller, like other contemporary thinkers, was dissatisfied with the social corruption at that time and saw the problems brought by the French Revolution. On this basis, he put forward his own aesthetic education thought, trying to create personal physical and mental harmony and rational improvement through aesthetic education, and finally realize social improvement. Letters of Aesthetic Education is a collection of 27 letters he wrote to Duke Augustenborg, which embodies his speculative aesthetic thoughts and becomes his most important aesthetic work. He inherited Kant and enlightened Marx, Marcuse and Bakhtin. He is an important figure in the transition from classical aesthetics to modern aesthetics.
