Is the human mind a "whiteboard"?

The human mind has unlimited potential, and the key is to explore her topic-how to give full play to her value!

It is not easy for human beings to know external things, and it is even harder to know themselves. It's even harder to know what you want.

In Europe, mechanical materialists in the18th century believed that the human mind was empty before knowing external things, just like a clean "empty monument"; When things that need to be understood, such as natural things, social activities or other people's ideas come into mind, they can be clearly printed on this "whiteboard". What's outside? What's on the whiteboard. On the other hand, everything on the "whiteboard" will certainly find a prototype in the outside world.

According to the whiteboard theory, if you close your eyes, you can't see anything, and you are in a "blank" state. Then when you open your eyes, everything in front of you-books, manuscript paper, glasses, cups, ballpoint pens and so on. -It will enter your mind through your eyes, and you won't miss anything. The mind treats the "guests" from the outside world equally and eclectically. This makes it difficult to produce things like "innovation" and "invention".

However, the actual operation of the mind is not the case.

Psychologists have done such an experiment: blindfold a hungry person and put a bunch of things in front of him, including a small piece of humble bread; Then he took off the blindfold. The subjects saw bread almost at a glance, grabbed it and ate it. Then ask him what else is in the pile besides bread. He was at a loss.

In fact, we have similar experiences in our daily life. In a large group of people, see the person you are looking for first; Scanning the advertisement column of the newspaper will help you find the advertisement you are interested in. Wait a minute.

All these prove that the human mind is not an empty "whiteboard" before it knows external things, but something that already exists.

Scientific experiments and life experience prove that our minds make choices after processing all kinds of information input from outside. This is the realistic basis for the mind to produce creative thinking. Among them, several important choices are: practical purpose, value model, knowledge reserve and so on.

The practical purpose in mind is what we want to achieve when we think about things or solve problems. Its language expression is: "For …".

Everyone does everything with a clear purpose in advance. This purpose guides people's thinking and behavior, and people can realize the existence of the purpose and imagine the beautiful scene after the purpose is realized.

As a result, our minds have a "tendency": we will pay more attention to things and problems that meet our actual purposes; For those things that have nothing to do with practical purposes, they are rejected.

Some things appear in our sight a thousand times and ten thousand times, but we "turn a blind eye". The root cause is that those things don't meet our practical purpose, and the mind doesn't feel the need to pay attention to them. For example, in a police school, graduating students are sitting in the classroom on the third floor, waiting nervously for the upcoming graduation exam. I saw the examiner walk into the classroom and go to the podium and say to the students, "Attention, everyone, now the exam begins! Please run to the first floor immediately and then run back to the classroom! "

Although the students don't understand, they can only obey orders. They hurried downstairs and ran back to the classroom on the third floor. As soon as the students sat down, the examiner's question came out: "How many stairs are there from the first floor to the third floor?"

For the vast majority of people, the stairs are just a passage to go upstairs and downstairs, and it is enough to achieve this practical purpose, regardless of how many floors it has. But for a policeman, he should be more observant than ordinary people, and be able to break the shackles of the usual "practical purpose" to find all kinds of information related to the practical purpose of "solving the case".
