He is a German postmodern philosopher, poet and writer. This well-known and little-known figure in China has his unique life experience and ideological characteristics. He is a university professor, but he denies other professors who are conscientious in education. He is a philosopher, but he is extremely eager to oppose the philosophy that appeared before him. He shouted a shocking slogan: reevaluate all values! Not only in the East, but also in the history of western philosophy, Nietzsche has always been a controversial figure. Nietzsche's philosophy is the product of the development of capitalist society to a certain stage, and he predicted the profound spiritual crisis of modern western society in a unique way. \x0d Nietzsche's thoughts reflected the demands and aspirations of the monopoly bourgeoisie that was forming at that time. He condemned the liberal bourgeoisie, calling them mediocre people who followed the old rules and dragged out an ignoble existence. It is believed that we must deny the decline of western civilization influenced by rationalism, Christianity and humanitarianism, advocate subjective fighting spirit and positive attitude towards life, and emphasize that evolution is a process in which power will realize itself, and the purpose of life is to exert power and expand itself. We advocate superman's philosophy and believe that superman is the creator of history and has the right to enslave the public. Ordinary people are just tools for Superman to realize his will to power. He opposed democracy, socialism and women's liberation movement, and even condemned doctors for saving lives as a crime. He holds that art is the expression of the will to power, and artists are people who highly expand themselves and express themselves. \x0d But Nietzsche did put forward new ideas. When Freud brewed his psychoanalysis, he was surprised to find that Nietzsche had expressed his basic ideas. Jaspers, Heidegger and all existentialists regard Nietzsche as a pioneer. Many western writers are also deeply influenced by him. Nietzsche's theory indicates that western society has entered an era of fundamental changes in values. Therefore, without understanding Nietzsche, it is impossible to understand the ideological trend of western philosophy, literature and society in our century.
