Whenever such a problem is encountered, the monster comes out. What is particularly annoying is that some people still don't admit that they believe in ghosts and gods, believe in the immortality of the soul, and want to dwell on science. This is so funny.
If we put the question of consciousness 20 years ago, we can roughly say that we don't know the cause of consciousness, but today, what is consciousness has basically existed in science. Ghosts and monsters should retreat politely and return to the cultural field where you should exist.
Many respondents like to mention near-death experience, which is a classic pseudo-scientific question. Because death is not a medical concept at all. This is just a standard for us to roughly judge the possibility of a living person dying in a short time.
Dying is dying, dying is not dying, but there is a great possibility that it can't be saved. There is no transitional state of death. To live is to live, and to die is to die.
The standard for declaring a person dead in medicine is called brain death. There has never been a record of a brain-dead patient being resurrected. As long as the brain is fine, our blood circulation and our respiratory system can be maintained by medical equipment.
Every year, a large number of family members of patients spend huge sums of money to maintain the vital signs of family members sentenced to brain death because they are unwilling to give up their lives. However, all these efforts are in vain. Maintaining vital signs is not that important and mysterious. Brain-dead patients will not come back to life.
The so-called near-death experience is nothing more than the rescue after the heartbeat stops and the breathing stops. Even just scared in a major accident. They are not near-death experiences at all, they are just daydreams.
It is absolutely absurd to do research for daydreaming.
Then some people may want to say, what will the world look like after death if there is no external consciousness?
This is a simple idea, I think, therefore I am. You assume that the world exists in your experience. But this is not the case.
When you spend a dreamless night, time passes as soon as you close your eyes and open them again. Where is your consciousness? When a vegetative person finally wakes up after years of coma, where is his consciousness these years?
The answer is completely unconscious. Consciousness is the activity of the brain. When brain activity is weakened, consciousness will be blurred or even disappeared.
You are your brain. Consciousness is your brain's explanation of its existence. The world is not as complicated as you think.
