Before philosophy, I thought I knew everything, but I was ridiculous and didn't understand why I thought. I hope everyone will come in and have a look. I can't understand it myself.

Your own problems put you in a contradictory position.

Your question contains several profound thoughts of the ancients on life:

I. Shunzhi: Who was I before I was born? Who am I after I was born?

Heraclitus: You can't step into the same river twice.

Third, the scientific proposition still being explored: the origin of life.

The following is an analysis of your question:

First, people are unique individuals because everyone has his unique DNA sequence and password, and these sequences and passwords are the most critical factors in the formation of vital signs.

Second, from the overall classification point of view, you are a factor of human groups and a * * * body. For example, your language must be the language used by people around you.

Third, people exist as individuals because they have the initiative to maintain their life cycle. For example, you can't stop your heart, you can't hold your breath and wait for death. All this is the subconscious of this individual at work. It is also an instinct of life.

Fourth, the problem of human intelligence is very broad and abstract to explain. My ability to analyze your problem alone is limited. Your question is the beginning and end of consciousness. Then I can tell you that human consciousness comes from the influence of the environment on people. For example, if you listen to a piece of music, your subjective consciousness can immediately reflect whether the music is elegant or harsh. Your judgment is also suitable for other people's judgment on others. This is a * * * knowledge, even if no one tells you that this song is ugly, there must be the same * * * knowledge. There is also a kind of knowledge that is passive. For example, in the last century, a neighboring country invaded China on a large scale, and almost all China people harbor hatred towards this neighboring country, but this kind of psychology is not active. Imagine, if you don't know this history at all, do you have hatred for this neighboring country? Man's consciousness is only a subjective response to the objective world, that is, one for three. Imagine how to go back to three without this. For example, if you stay in a normal place now, no one has any direct or indirect contact with you, and you feel comfortable, then even if you want to have a tingling sensation in your skin, it is impossible. Another example is neighboring countries. If you don't know the history of the last century, will you still hate them?

Fifth, consciousness comes from the brain and its destination is behavior and language. For example, a few years ago, some radical youths spontaneously boycotted Japanese goods and publicized the correctness of this behavior to others. Even if you just think, there must be a certain amount of language flowing in your brain, but there is no sound or image recording.
