In Hongjing Detention Center, police officers are installing televisions.

Lin Chen promised to be addicted to things, and never thought about avoiding them from the beginning.

Shen Lian leaned her legs, like a cute little girl, looking forward to the black screen lighting up as soon as possible.

"Where did I say ..." Lin Chen was distracted by turning back, so he suddenly asked.

Shen Lian raised her shackled hand, pinched her thumb and forefinger together, pretending to pull out a slender thread, but didn't speak.

Lin Chen nodded: "In the beginning, after experiencing the choice of real moral dilemma, I was very at a loss. In order to fill my ignorance, I read a lot of books discussing the origin of morality and the evolution of human psychology, but I read The more I get, the more I'm at a loss. I believe in fairness, justice, freedom, rationality, kindness, and beauty ... These things really exist, but people have only found some words fictional in order to maintain human society. Something that appears. "

He talked nonsense and did not avoid this experience. In fact, at that time, he thought that if he wanted to defeat the other party, he had to unlock the answer, but everyone knows that no one can unlock the real answer.

Shen Lian sat with her arms folded, and the contempt in her eyes was obvious. A man with a strong conviction like Shen Lian should look down on him as a stubborn person.

"Some people who engage in philosophy will choose to commit suicide, which is probably the reason. The purposeless chaos is too easy to be overwhelmed." Lin Chen put his hands on the table and said at will: "Take care, I should also Suicide. But one day, I suddenly realized, why do I have to find a definitive answer? "He looked at Shen Lian and smiled." Look, this is what makes me different from him. "

"Social contract, natural jurisprudence, collective subconsciousness, selfish genes ... I can recognize and understand many opinions, and I also understand the criticisms made to them, so I am at a loss, I can't find anything absolutely correct. But he Different, he is paranoid. He looks at the history of human evolution and finds what he recognizes. He regards it as life-saving straw, regards it as truth, and inculcates it to you. He desperately needs to be recognized by his classmates Point of view, he even needs his rebellious society to agree with his point of view. Faced with such a lunatic, an ignorant and incompetent person like me can do ... "Lin Chen paused, he looked to Shen Lian, and said," I All I can do is figure out what I'm good at-what he believes, what he's thinking, what he's going to do, and then ... defeat him. "

The interrogation room was really small, the walls were gray, and his voice hit the walls and disappeared cleanly.

The clouds flowing out of the iron window seemed to freeze, and there was no sound.

"Well."

Shen Lian laughed.

The woman looked at him with his uncle's eyes, Lin Chen felt that this was also normal.

He said: "He used the isomer of tern to prove the physiological necessity of the so-called criminal behavior. He used the tram problem in front of everyone to prove the widespread selfishness of mankind. He wanted to prove that in matters of concern to one's own interests The morals held by most people in this society are false and broken. This is an obvious motive, but ... then? "Lin Chen's fingertips were ruined between him and Shen Lian. Tap on the table and said, "Prove what happened, this solid social contract between people in society will not really break into powder because of a lunatic game. So until I saw 'Balance game on the wire' 'Before this word, I couldn't understand what he wanted.' Lin Chen paused, his expression suddenly abruptly, 'In fact, he proved to be crazy than I expected.'

...

Hongjing City Bureau, command room.

Xing Lianlian is not very good at doing this kind of thing, but at this moment Lin Chen is struggling and trying to break the spiritual belief of Shen Lian a little bit, then he must bear something else.

He ordered a glass plate and said, "The original meaning of the word is a hypothesis, referring specifically to the subtle moments in the history of human moral evolution. For example, put aside all the concepts of modern society in your mind. Without Jinyiyushi, we returned to Africa 45,000 years ago. At that time, African Homo sapiens were modern people in an anatomical sense. "He paused, and said," Yes, yes, and We are the same modern people. "

Xing Cong pointed to everyone in the room and said, "We are all a group, but at that time we didn't have any moral and legal concepts like we do now. We and chimpanzees also look alike. You grab me on the site. I will kill you if there is no problem with women. There is a view that genetic selfishness creates the selfishness of our behavior. At that time, each of us was a born 'egoist'. But over time, we live in There are more and more people in the ethnic group, and mistakes appear. "

"I am powerful and can kill others at will and seriously threaten your life. I also stand behind a vote of supporters, and the two sides confronted each other. At this time, the highly respected Minister Shen stood up and spoke to everyone. You should die. As other people in the ethnic group, you have been intolerable for a long time. You have united and killed or expelled me and my champions. Accepting the call of Minister Shen to stand up against my warriors, with loyalty, courage and compassion And so on, these people are 'altruists'. "

"The wave after wave of extremists has been wiped out, the ethnic group is gradually in a stable state, and because of stability, it is more competitive and therefore able to multiply and grow. This is the result of natural selection. The definition of morality is also through altruism The reproduction of the person is gradually fixed, human beings have rules and laws, and the social contract comes from this, which is the group selection theory of moral origin. "Xing Conglian said here, looking at all the people present, solemnly," However, this Is everything really an inevitable consequence of natural selection? "

He didn't give everyone present time to ask directly and simply: "Is there a dangerous moment in the course of human evolution, the" egoist "forces I represent and the" altruistic "forces you represent A delicate balance has been formed. This is a moment of life and death. After either party gains the upper hand, society will form two very different situations. If you win, society will become what you hope; and once I succeed, the offspring who carry my gene It will lead the entire human society to the abyss I expect. "

He put his hands in his pockets, and said extremely ruthlessly, "This is the balance on the wire. It is a great moment that truly determines the shape of human society in the future."

...

A remote control was put down in front of Lin Chen.

Lin Chen picked up the remote control, nodded his thanks to the police officer, and asked Shen Lian: "So, what is his purpose?"

He asked, and then replied, "I don't think his purpose is to create this moment right away. He wants to go deeper. What he wants to do is to provide a great possibility for the recurrence of this moment in the future."

"He wants to plant a seed of selfishness in everyone's heart."

"This seed is planted in the minds of the choosers, in the hearts of the abstainers, and even in the minds of the observers. The seed is reproduced and grown by humans from generation to generation, and will be created in the future for all extreme egoists like you who are not tolerated by society A possibility. "

"Someday, the egoist community will eventually grow to an extremely terrible size, and at that moment, humanity will once again usher in a balance game on the wire, and once again have the opportunity to choose fate."

"That's what he really does."
