Our perception of the world is based on consciousness, and the understanding of consciousness is the basis of our cognition. What is Consciousness?How to understand consciousness?In order to understand what consciousness is, we must first understand how consciousness is generated, and when we know how consciousness is generated, it is easy to understand what consciousness is.
There are many human consciousnesses, first of all, we explain the most common kind of consciousness generation**: direct consciousness, that is, the consciousness that can be directly produced by human sensory systems such as audio-visual touch, and we take the generation of visual consciousness as an example.
How does visual awareness come about?The following is a comparison of the screen imaging principle of television.
The simple process of imaging a TV screen is as follows:
The light reflected from the object is captured by the camera - converted into electronic information flow - the light-emitting transistors on the screen are controlled by the electronic information flow, and different transistors emit different colors of light, thus forming a virtual image of the object on the screen.
The process by which human visual consciousness arises is as follows:
We can see an object because of the light emitted or reflected by the object itself, which is a flow of photons, a kind of energy, and conducting biocurrent in our nervous system is also a kind of energy: electrical energy, the role of the visual center in our brain, is to convert the bioelectrical stimulation into the consciousness of the object, which is just like the crystal diode in the TV screen can emit different colors of light when it encounters an electric current, and when our visual center is stimulated by bioelectricity, it will also stimulate the corresponding function, thus producing visual awareness of the object。
Therefore, consciousness is the result of the brain's induction of energy stimuli, and what kind of energy stimulus there is, what kind of consciousness there is.
To put it in a simple formula: consciousness = brain + energy, both of which are indispensable.
Of course, some people will ask, that's not right, when I don't see something, I also have consciousness, for example, I don't have an apple in front of me, but I have the consciousness of an apple, what's going on?Of course, we are talking about direct consciousness above, that is, the consciousness that can be produced directly when the sense organs are stimulated by the outside world.
And consciousness is not limited to direct consciousness, but also indirect consciousness, what is going on?When you see an object, you not only have awareness of the object in the brain, but you also remember all kinds of information about the object, including shape, size, color, and so on.
One of the functions of the brain is to memorize the consciousness generated, and to process and modify the existing memory. For example, if you look at the empty table in front of you, you can realize what you can put on the tableOf course, you can think of putting all the things in your memory on the table, and even you can process and transform the things in your memory, and then put the transformed things on the table, all of these consciousnesses are based on your previous knowledge and memory, which is indirect consciousness.
And the fundamental difference between human beings and animals is this creative processing ability of knowledge memory.
Of course, a new question arises here, what is knowledge memory?In fact, according to the research results of modern science on the brain, we already have a basic understanding of knowledge memory, so what is knowledge memory, how knowledge memory is stored in the brain, and how to use it, we will talk about this next time.
So, to summarize what we have talked about today, our explanation of the generation of consciousness, we will know, consciousness, what is it?
Consciousness is the result of the brain's response to various internal and external energy stimuli, and consciousness cannot be separated from the brain and energy stimulation, both of which are indispensable.
By understanding consciousness, we can know the answers to many questions.
For example, do plants have consciousness?Of course not, plants don't have brains and can't produce consciousness at all. Although the plant has no consciousness, it does not prevent it from reacting to energy, for example, when spring comes, the plant knows that it is time to bud and grow, and when autumn comes, it is time to drop leaves, etc., all objects can respond to energy accordingly, but this is not consciousness, only creatures with brains will produce consciousness.
Can consciousness be separated from the body?This is what everyone is most concerned about, does the soul exist?Can it exist in isolation from the body?When we understand what consciousness is, we can basically answer this question.
Consciousness is dependent on the brain, without the brain, there is no consciousness, but the essence of consciousness is energy, can energy exist apart from matter?Absolutely, but consciousness that is detached from the brain is not consciousness, but energy.
Energy is not as stable as matter, it is constantly emitted to the surroundings. When we are alive, we are already constantly exuding energy to the surroundings, which is a person's "aura". Of course, the energy emitted by most people to the surroundings is very weak and miscellaneous, so it is difficult for the people around them to feel it, only when the energy field of one person is strong enough and pure, the people around can clearly feel it, this person is extraordinary, energetic, and has a strong aura.
When a person is alive, his energy will continue to radiate outward, and people die like a lamp going out, after death, his energy is like a candle is blown out, losing stability, and will soon dissipate in the surrounding environment, or be absorbed by the surrounding environment, or this is called "reincarnation", of course, here is just a superficial talk, and so on in detail later.
Human beings come from nature, human beings and the universe have the same origin, the universe basically contains matter and energy, human beings also contain matter and energy, among which the energy perceived by the brain is consciousness, human consciousness is more advanced, just because the human brain function is more powerful, in fact, the essence is no different from other animals, other animals also have brains, can also respond to energy stimuli, and also have consciousness.
Human beings are not myths, seeing this, it is estimated that many people will feel a little hopeless, human beings, there is no difference, matter and energy, human beings do not exist beyond this universe. Human beings are just creatures that live within the rules of the universe, or rather, creatures that are a little more advanced.
Forget it, I don't want to write it today.
