"When you stare at the abyss from a distance, the abyss is also staring at you." From the other side of good and evil, there is another sentence ahead: "Those who hit monsters should be careful not to become monsters." Nietzsche likes to write books with aphorisms, which he thinks is an "eternal" form. He said that his vanity is to tell what others said in a book in ten sentences and what others didn't say in a book ... (from "Idol's Evening") The immortal motto lies in its rich meaning and infinite interpretation, so the "abyss" of this sentence can also have many different symbolic meanings. For example, when you strongly hate and despise ugly and vulgar things around you, these things will occupy your heart and make you polluted and ugly. At the same time, negative emotions will make you physically and mentally uncomfortable. When you are at war with some kind of "source of pain", you stare at "pain", and the pain stares at you like an abyss, which will continue to affect you and make you unable to escape. Nietzsche reminded people that staring into the abyss has dangerous consequences and should be vigilant. Man is a soft rope between the beast and superman-a soft rope hanging in a deep valley. This sentence seems to have nothing to do with "people who can't kill me make me stronger", nor does it directly mean that we are closer to Superman, and there is no rolling in the deep. My understanding is that the key point is in the first half of the sentence. Nietzsche hopes that people will go to superman instead of staying in animals. A long passage behind all expresses this tendency-Nietzsche said that he loves such a person: he can sacrifice himself to produce Superman on the earth, and he can live or die for his own morality. Praise precedes behavior, practice exceeds commitment, and he is ashamed to see that dice are beneficial to him. Those who waste their souls and are neither thanked nor thanked do not hesitate to cross the bridge, which makes the future life meaningful. They are willing to die for the present people and pursue the declining ones. Because such people are more pure, regard themselves as a process, choose pure and powerful spirituality at all costs, and sacrifice themselves to become superman or superman. So what is the meaning of abyss (or "deep valley")? It means that man is just a rope between animals and superman, and the meaning and value of life are only here. There is no other way, just like a rope hanging, there is only an abyss below, which makes no sense. There is a paragraph behind the original words that says, "It is dangerous to walk to the other side, it is dangerous to give up halfway, it is also dangerous to look back, and it is also dangerous to tremble or not to move forward." This is the abyss. What is the abyss? It not only represents nothingness, but also vividly describes the sinister background of this rope. The rope is in mid-air, and every step to the strong is risky. Giving up halfway will only waste time, energy and will, let the opportunity slip away and make it more difficult to move forward.
