Nietzsche talked about positive nihilism and negative nihilism. In his view, their premise is extreme nihilism. What is extreme nihilism? "There is no truth; There is no absolute essence of things, and there is no' thing itself'-this is a kind of nihilism in itself and an extreme nihilism "[2]402. Nietzsche believes that positive nihilism is a symbol of the improvement of spiritual strength. "This may be a sign of the strong: spiritual strength may grow in such a way that the previous goals (beliefs and creeds) are no longer compatible with it ... on the other hand, it may be a sign that it is not strong enough, with the aim of creatively setting another goal, a reason and a belief" [2] 4065438+. He believes that this is a destructive force of violence, its opposite is negative nihilism, and it is a state of silence and inaction. Obviously, Nietzsche believes that this positive "nihilism" is the ideal of spiritual supremacy, and the ideal of the richest life is both destructive and ironic "[2]405. In fact, Nietzsche thinks about nihilism from the perspective of strong will, and sees more positive nihilism, preparing for the emergence of strong will and superman. He believes that the life movement represented by strong will and superman will replace nihilism at some point in the future. Logically and psychologically, it is based on complete nihilism, which can only fall on nihilism and only come from nihilism. Here, Nietzsche calls positive nihilism complete nihilism, and the emotions and symptoms of this complete nihilism are contempt, sympathy and destruction. Its apex: a theory that can stimulate happiness, disgust, sympathy and destruction of life, and is taught as an absolute and eternal theory [2]749. Nietzsche linked the so-called complete nihilism with the theory of eternal reincarnation with the function of cultivation and reproduction, and thought that complete nihilism was a test of life, which would eliminate the weak and cultivate the strong, and urge people to measure value with the power of life: "The old value comes from the declining life and the new value comes from the rising life" [2]749. This positive "eternal samsara thought is a hypothesis based on practical rationality, and it is a hypothesis for cultivating new philosophers and even superman in the future"
