For example, Voltaire said in On Epics: "Since the Renaissance, people have followed the example of ancient writers. Homer, Demo Stennis, Virgil and Cicero seem to unify all the ethnic groups in Europe under their rule, and form many ethnic groups into a single literary republic. However, in the overall coordination, the customs and habits of various nationalities have also caused special aesthetic tastes ... "He put forward the universality and particularity of artistic aesthetics here. In his understanding of the essence of beauty, he believes that beauty is an emotion that can make people marvel and be happy. He also believes that art can cultivate people's elegant taste. He actively supported the dance theory of18th century dance theorist Norwell. He praised, "Like Prometheus, you created the shape of a person and put your soul in it." Voltaire's thought directly influenced the reform of ballet art at that time. Under the influence of his thoughts, ballet was separated from the amateur programs of opera and became the art of expressing dramatic plots. The posture and movements of the dance closely revolve around the plot.
