I personally believe that existentialism is a form of resistance against nihilism. In the Western world, with the advancement of science and technology, the development of productivity, and the rise of capitalism, the old Christian ideological framework gradually disintegrated. Along with it, the moral structure brought by religion began to collapse. "God is dead" is Nietzsche's most powerful summary of this transformation. People need to free themselves from the influence of God to establish their own moral framework, countering the moral collapse brought by nihilism and capitalism. The even greater moral collapse caused by World War I and World War II prompted deeper reflection. Existentialism thus asserts that there are no external, objective moral laws to constrain human behavior, aligning with Nietzsche's philosophy of the Übermensch. However, unlike Nietzsche, who almost entirely rejected traditional morality, existentialism holds that an individual’s actions and moral principles are declarations of how they define themselves in relation to the world. While choices are free, individuals must take full responsibility for the consequences of their actions. This, in fact, places a greater responsibility on each person—a responsibility regarding the meaning of existence and their relationship to the world. Through this process, each individual must assign moral significance (and, simultaneously, self-significance), thereby resisting nihilism and absurdity. But I think this philosophical ethics framework may not enable society to follow approximate moral standards. Therefore there are still some social problems.
