Because man is a social animal. Just like animals are divided into social and solitary animals, social animals must be afraid of loneliness, while solitary animals like loneliness. We can compare cats with canines. Cats (except lions) are almost solitary animals, so stray cats can survive well, but stray dogs die quickly. All primates and humans are social animals. Looking at the animal world, monkeys are willing to stoop to humiliation because they are afraid of being kicked out of the group. When a monkey king gets old and is replaced by a new monkey king, the most severe punishment for him is to attack him in groups and drive him out of the group. When the monkey king leaves the group, he is not far from death. Even if the mountains and fields are filled with abundant fruits, it cannot survive alone. From this, we can deduce that why people pursue social recognition, are willing to give up their individuality, and follow independence is determined by our inherent inability to be alone, not by our morality. Indian philosopher Krishnamurti believes that people read, entertain, make friends, fall in love, get married, religion, belief, work, activities, interests, hobbies, power and money desires are all for distraction. What kind of heart is there, the heart of loneliness, the fear that I will feel lonely because I have nothing to do, and the fear that the loneliness will cause inexplicable anxiety, panic and uneasiness. In fact, no matter how hard people try to escape loneliness, loneliness always accompanies us every minute of our lives. If it must be described, loneliness is the shadow of the soul. The brighter the place, the deeper the shadow. Loneliness cannot be defeated, let alone suppressed. The best way to deal with loneliness is to be aware of its existence and be willing to coexist with it. Being aware of loneliness is by no means an easy task, because as soon as loneliness appears, people will immediately do something to "distract" it and prevent the mind from feeling its existence. There are two types of people who can truly survive with loneliness. One is a monk who hides in the mountains, away from human society, with a pure heart and few desires, an empty body, and reaches the state of enlightenment. The other is a person like Tom Hanks in "Isolated Island". A person is forced to live on an isolated island. When loneliness strikes, he is extremely frightened but has no way to escape. He slowly accepts the loneliness and becomes helpless. Can't get up. Loneliness is a kind of existence, don't run away from it, and don't dare to challenge it. All one can do is to be aware of and accept it calmly, and accept it to coexist with life. Only in this way can we avoid trying to please certain cultures, concepts, groups, power, money, and relationships because we are afraid of being alone, and truly live our lives.
