My life has an end, and there is no end to knowledge.

As this sentence came to his mind, Xu Guangling suddenly stopped, because he thought of a question, a very critical question.

That is, what is "knowing"?

In an instant, all the information related to knowledge that he had been exposed to in the past was raised one after another, appearing in Xu Guangling's consciousness.

Intelligentsia.

Ignorant girl.

Knowledge is life.

Those who know others are wise, and those who know themselves are clear.

Life is full of categories, and knowledge is the most virtuous.

The greatest purpose of life is not knowledge but action.

All our knowledge begins with the sensibility, then enters into the intellectual, and ends with the rational.

......

Knowledge is life.

Xu Guangling's consciousness was briefly fixed on this sentence.

This statement is obviously inaccurate, knowledge is not life, but knowledge does belong to life. Inanimate things, no knowledge.

Knowledge, knowledge and knowledge.

Perception, awareness.

Using the "body" to perceive, such as fragrant smell, such as sweet and sour, bitter and salty, such as good sounds and unpleasant sounds, such as beautiful things and bad things, these do not need to rely on the outside world, nor do they need to rely on any understanding, but only rely on the judgment of the body itself.

Recognize with "heart".

The sweet and sour at the perceptual level can be elevated to the cognitive level of "sweet and sour is me";

The smell of fragrance at the perceptual level can be elevated to the cognitive level of "dwelling with good people, such as entering the room of Zhilan, and not smelling its fragrance for a long time, and dwelling with evil people, like entering the abalone, not smelling its smell for a long time." ”

The good and bad at the perceptual level can be raised to the music and noise at the cognitive level, and the five tones and seven tones are further born in the music, and then the music is generated on the basis of the five and seven tones, and then the music can be sung with lyrics, and in addition to singing, it can be combined with the body to form a dance......

Noise is not only unpleasant, but it can also be destructive to people, what areas of noise have an impact on people's psychology, and what areas of noise begin to actually destroy the body's functions.

......

Perception + cognition to form the entire knowledge system.

Among them, perception is the premise and foundation, and cognition is the sublimation of this premise and foundation.

Without perception, there is no way to talk about cognition, let alone any meaning.

No matter what kind of music, it is meaningless to the deaf. No matter what color it is, it makes no sense to the blind.

For people who have lost their sense of smell, smell has no meaning, and for people who have lost their sense of taste, delicious food and even food have basically lost their meaning.

The human knowledge system is based on the perception of the human body, and then, to satisfy the perception?

At this point, a street appeared in Xu Guangling's mind.

It was a random street in the map in his mind, and on this street map, Xu Guangling's attention gradually shifted from left to right.

It's a good smell of mutton restaurant.

This is a restaurant that Xu Guangling patronized, and through Shennongjue, he entered by smell.

The mutton is very authentic, the heat is also well mastered, and then the mutton soup, mutton noodles, haggis, etc., are quite palatable, and therefore, the price is higher, more than 50% more than the same kind, but from the situation, it is still very popular with the surrounding residents.

In fact, if the craft or craft can be popularized and supported by funds, the mutton restaurant is fully qualified to form a mutton restaurant that is interlocking across the country or even the world, just like the "old godmother".

In the competition, you don't need to exceed the same kind too much, just a little, and it is enough!

Wenhui Print Shop.

Colorful nail salon.

Nuan Nuan (cake shop).

Fruit shop.

Tea shop.

Bookshop.

Hospital.

Opticians.

Notebook shop.

Mobile phone hypermarket.

......

Xu Guangling didn't know how many streets like this he had walked, and on this day, at this moment, he looked at these shops from a special angle, and then his consciousness shifted from these shops to people.

All sorts of people.

Children, Students, Teachers, Workers, Businessmen, Cooks, Doctors, Music Practitioners, Scientific Researchers, Soldiers, Weapons Researchers and Developers......

All the different professions are ultimately summed up as "useful to society".

To be useful to society, that is, to be useful to human beings, who can be all human beings, or a part of the population, or even just one person.

It is useful to all mankind, such as scientific researchers, who study how to develop brackish lands, study desert management, and study the cultivation of seagrass.

It is useful for a certain group of people, such as music practitioners.

Useful to a certain person, such as a private chef.

And all the projects or activities are based on, "let yourself survive", "let yourself survive better", "let your life have meaning", and all these projects or activities are positioned to, "let human beings survive better", "let groups or tribes survive better", "let the body and mind perceive have a better experience".

The center of all human activities is also people.

Subjectively for oneself and objectively for others.

For yourself or for others?

Basic survival, and on top of survival, colorful perception and life experience.

In other words, everything starts from "life", and then everything returns to "life".

When his thoughts were deduced here, a basic framework had been formed in Xu Guangling's mind, and then his consciousness continued to rise.

Anthropology.

The study of the human body, including diet, sleep, exercise, everything in the human body, and any one of these aspects is enough to spend a lifetime in a person.

Of course, mastering any aspect is enough for this person to "learn something", and then, he can "use it for society".

Medicine.

Dietetics.

These should be regarded as the knowledge closest to "life", and among them, medicine is closely related to most people, and dietetics is related to everyone, but dietetics is a simple and complex system.

What is edible, what is not edible, what is delicious, what is not tasty, what is nutritious, what is not nutritious......

Initially, humanity knew nothing.

However, with the development of civilization to the present, the "achievements of civilization" have long formed a rich accumulation in this aspect, coupled with a fairly mature self or market supply, so for the vast majority of ordinary people, food is not a knowledge, and there is no need to rise to learning.

Eat every day?

Just go to the market and buy groceries and come back and make it.

You can do it yourself.

To eat well, or to spice it up, you need to have the participation of a "chef". When the standard of living reaches a certain level, if you want to pay attention to it, you need the participation of "nutritionists".

......

Xu Guangling sorted out all the industries he knew one by one.

But not much.

But even then, it took him a lot of time.

Eventually, his mind turned to himself. Everything starts from life and returns to life, and everything starts from itself and will return to itself.

Who am I, where am I, and what am I doing...... Where did I come from and where am I going...... Xu Guangling didn't think about these messy things, what he was thinking at the moment was actually very simple, "I need, I should, I can, what kind of knowledge system should I build?"

The path of the Grand Master.

Well, he's walking on this path, and that's probably the core path of his life.

Is the Grand Master the End?

Not necessarily.

It's not even the end, maybe after really becoming a great master, you will find that it is just a new starting point.

It's entirely possible.

At present, walking on this road, he relies on "dreams".

And in the civilization of man itself, is there knowledge that will help him?

Some.

Anthropology, biology, botany, zoology, etc., can help him to develop an understanding of life, the body, and by the way, medicine.

In the long run, exposure, learning, and even research of this knowledge should be helpful to his core path, not for the time being, but definitely in the future.

Can the "dream" support him for a lifetime?

Maybe.

Not necessarily.

But in any case, self-reliance is never wrong.

Also, cooking, music.

These are also the two aspects that Xu Guangling is currently in contact with, before, Xu Guangling classified them as embellishment, but now it seems that their status can be improved, whether it is cooking skills, music, they are all around the body.

An in-depth study of them, perhaps, could have yielded some unexpected benefits to his core path.

This is basically the end of the disturbing thoughts.

Xu Guangling didn't think too much and too deeply, but only established or further clarified a few points:

1. Most of his time and mind, his main body and mind, will be on the "Great Master Path", which will be the core path that he will continue throughout his life.

2. In addition to walking on this path, his spare time will be devoted to the study and research of "life", including biology, medicine, and all the knowledge that human civilization has so far not had but has anything related to "life".

3. Leisure and leisure, the study of the branches of life, the eyes, ears, nose and tongue of the sensory system, as well as the knowledge system extended from these senses, such as art, music, incense, cooking, etc.

This one, two, three, one is inside, two is outside, and three is miscellaneous.

At this point, the thoughts are completely clear.

This is the path of the present, this is the path of the future, and this is the path of a lifetime.
