The high probability that this question can be asked is to see reductionism + determinism and then think that everything is predictable; or to see that quantum theory believes that quantum uncertainty overturns determinism and thus the aforementioned view is invalid. Reductionism anyway itself is fine, so the real point is to recognize this determinism. First of all, we have to clarify the definition of this so-called free consciousness. There is a definition that you define consciousness as free if the rest of nature (regardless of whether you are a person or a thing) other than the person concerned cannot predict the person’s behavior or thoughts. If it is this definition, then the problem is a technical problem. At least there is currently no accepted theory that can effectively prove the incalculability of the human brain. Of course, it is technically impossible at present, but from a theoretical point of view, you can only say that it is possible in principle. In this case, it can only be considered that consciousness is not free in principle, because it can be predicted in principle. Another definition is related to determinism, that is, the definition of consciousness is freedom. iff determinism does not hold. Determinism must be established in classical physics, so the only possibility is that quantum theory may overturn determinism. However, whether quantum theory can overthrow determinism, for now, highly depends on the interpretation you adopt. If you use the Copenhagen interpretation, then every measurement (or every decoherence I should say) will encounter randomness. Of course determinism is not valid at this time. But if you adopt a multi-world interpretation and think that every decoherence is to choose one of many different possible worlds, then determinism is still valid. Because at this time the entire universe obeys a Schrödinger equation: where is a quantum state in the entire universe, and is the Hamiltonian of the entire universe. In this case, even if a universe is randomly selected for every decoherence, it still follows this certain differential equation as a whole, so the determinism still holds. In fact, the competitiveness of the multi-world interpretation is basically here: compared to the Copenhagen interpretation, the multi-world interpretation does not need to undermine determinism. If it weren’t for this powerful feature, the creation of a bunch of not even wrong parallel universes would have to be eliminated by the Occam’s razor principle, and would certainly not be recognized by the academic community. So the conclusion in this case is that if you believe in the Copenhagen interpretation, then consciousness is free; if you believe in the multiworld interpretation, then consciousness is not free; if you believe in other interpretations… Then re-analyze whether determinism is Still established. the above.

The subject, you do not play cards according to the rules! What you are asking is the unsolved mystery of the world. Our brains are indeed made of matter (particles), but the combination of these matter has appeared consciousness. Consciousness is usually opposed to matter. Therefore, we divide philosophy into idealism and materialism. For thousands of years, from philosophy to physics, there has been no reasonable and authoritative explanation for the generation and mechanism of consciousness. According to Baidu Encyclopedia: Free will (English: Free will) does not have a definition recognized by all parties. The definition of free will in philosophy is not unified; and the “free will” that people talk about in everyday life is different from the “free will” understood by the judicial and psychological circles. In the broadest sense, free will is the ability of people to decide whether to do something according to the conditions they have. The existence of free will has always been a core issue in the history of philosophy and science. It is still arguing even today. Of course, in physics, there is still a theory that studies consciousness from the perspective of quantum mechanics. Anyway, quantum mechanics is unresolved! If this problem is really solved, it will simultaneously solve the philosophical problem for thousands of years! Not all questions have answers (can be answered nonchalantly).

There is a concept called Laplace Demon. The general idea is that if there is such a “monster”, he can get an infinite amount of effective information, and then it has infinitely high computing power, does it mean that he can calculate the state of everything at every moment? In fact, this is a question of determinism. Is the state of all particles at the next moment already determined at this moment? It’s not that the Laplace demon does not exist, and determinism does not exist. Not only is the state of things at the next moment indeterminate, even the things that have happened, the state at this moment is not completely certain. At least as far as current physics is concerned. Among the existing 93 answers, few mention the uncertainty principle. Can explain, less. It is also interpreted as the principle of uncertainty. Simply put, at the same time, the particle’s position and momentum are [impossible] at the same time as accurate values. It is not a technical limitation, at least judging from the existing mathematical derivation, this is the essential attribute of microscopic particles. A thing that either doesn’t know where it is, or doesn’t know where to move, and how fast it moves. How is it possible to mechanically determine the state of the next moment? Therefore, human will, I dare not say that it must be free. But it is definitely not determined by the deterministic calculation of particles.

What physical laws do particles follow? On the quantum scale, the particle is a probability distribution, which is an attribute of the particle itself. This attribute determines that the physical law followed by the particle is probabilistic, not reductionist. Therefore, contrary to our concerns, the universe is “free” from the particle level. What we should worry about is whether we can build a model to accurately predict particles? The interaction of particles has made the universe have formed a chaotic system from the most microscopic scale. The mathematical language has not been able to construct an analytical model to describe this system, so we should be more worried about whether the chaotic system can be described? Our consciousness is precisely based on these two premises. Particles are free, and the interaction of particles cannot be modeled. In this way, do we still have to worry about the freedom of consciousness? It is completely unnecessary. On the contrary, what we need to worry about is our own “security”. The future may never be known to us. This agnosticism is precisely the source of human fear. We are as free as monkeys exiled in the dark forest, and at the same time as fearful as monkeys. This kind of freedom is a kind of relative freedom, because we can’t get rid of fear, which brings us heavy spiritual shackles. So what is absolute freedom? One day, we can invent a tool to accurately describe particles, and at the same time build an accurate model for the chaotic system, and then we can explain all the history in the universe and predict all the future in the universe. At that time, we will have no fear, and even there will be no other than us, we are the universe. This freedom is called absolute freedom.

Until the definition of ‘freedom’ is clarified, such a discussion is meaningless. In fact, in the context of classical mechanics of determinism, there is also the term ‘degree of freedom’, which measures the potential diversity of system motion. For example, a rigid body has three translational degrees of freedom and three rotational degrees of freedom. The more degrees of freedom, the more information is needed to predict the future behavior of the system. If this definition is applied to social sciences, it can be considered that the ‘degree of freedom’ of an individual is negatively correlated with the ability to predict the individual’s behavior/preferences/thoughts with limited information. For example, it is difficult for me to judge the taste of strangers in front of me for salty/sweet tofu by appearance/gender/age/education/hometown/work, which shows the individual’s freedom in food choices; but I can judge the origin of a conservative state with a high probability The white male manual worker of is a supporter of Maga, indicating that the individual has limited freedom of thinking in political standing (although he thinks he is very free). Under this definition, even if the underlying mechanism follows determinism, it does not hinder the existence of ‘freedom’. The competition between the amount of information available and the complexity of the system is the key. See the next article for details. In addition, it is not an insightful approach to reconstruct the operating law of the brain (or whatever) system from the law of motion of the constituent particles. It’s not that it’s not feasible. But in fact, each scale has its own unique laws. Changing the laws of the next-level scale often has little impact on this scale, and may just lead to changes in some parameters in the laws of this scale. This miracle-the separation of scales-is one of the reasons why we can understand the world.

It doesn’t matter whether the human brain is made of particles, or whether the human brain symbol conforms to the laws of physics. We have to pay attention to one thing first. Freedom generally means that we can act according to our wishes without any hindrance. The question here is that “is human consciousness still free” refers to whether our desires are free, that is, whether we can determine our own desires. But who, by what, decides the desire? Do I rely on another desire of myself to decide this desire? I want to go out, I freely decide that I want to go out. That is, I want to go out, which leads to me wanting to go out, which leads to me wanting to go out… Is this thing called freedom? Is the concept of this thing even self-consistent?

In fact, the question you are talking about is abstracted out as “Does God roll the dice?” From a pessimistic point of view, all the development of later generations is determined as early as the moment of the initial explosion, because it is mainly based on the laws of physics. Everything can be inferred. Here, human consciousness depends on matter to exist, so consciousness is actually not and impossible to be free at all. But from another perspective, in a chaotic system, the development of later generations is unknowable or incompletely knowable, so here we need to distinguish the relationship between matter and spirit. If spirit dominates matter, and matter restricts spirit to a certain extent, then human consciousness is a relatively free state. And if matter dominates the spirit, then human consciousness is completely affected by matter, and the chaotic system will affect matter, then human consciousness is relative freedom in another situation. Of course, in my opinion, human consciousness can never reach absolute freedom, because the interaction and influence between spirit and matter are like internal and external causes, and everyone’s consciousness is bound to be confined to a material age. , So in my opinion, human consciousness is a relatively free state. Can you ask this question? Say it is philosophy, or philosophy, or physics, it’s also physics. It’s also from another angle to point out the entangled relationship between philosophy and science.

What is free consciousness? The subject actually doesn’t know what free consciousness is. And there is no real definition of “free consciousness”. The “consciousness of freedom” in the subject’s imagination is probably the “consciousness of absolute freedom” that is free from any external influence and does not require any external information. But where does consciousness come from? Consciousness is the information system produced by the brain processing the sum of all external information received by a person. Consciousness is the result of these reasons. The consciousness of absolute freedom does not exist. The free will we often say refers to not being forced, induced, or deceived by others, and being able to make decisions based on the correct information obtained by oneself.

Let me talk about the subject of the subject first. The subject believes that particles follow the laws of physics, and the brain is composed of particles, so human consciousness cannot be free. First of all, the subject implies three hypotheses: 1. “We have discovered and known all the laws of physics, and the motions of objects revealed by all laws of physics are determined.” 2. “The human brain is equivalent to human consciousness.” “3. “People may be free-conscious.” Let’s start with the third one. At present, psychology believes that people do not have free consciousness. In other words, we have always believed that the commander and CEO who really exist in the brain does not exist. Our self-awareness may be closer to an audience reader. The thinking mode and operation mode of the brain are much more complicated than we think and know. What’s more, our thinking operation is not necessarily just the brain where “a person thinks blindly” or other body parts are also participating together. Therefore, this is tantamount to saying that the second hypothesis is not necessarily true. Finally, we know that the entire world hides countless unknown secrets. What we may know at present is only a very small part. Moreover, quantum mechanics just shows that the world is not as “definite” as we think. The world is unknown, including our brains and the way in which our brains work. So even though I agree with your conclusion that “people do not necessarily have free consciousness”, I do not agree with you inferring the above process. Thank you! I wish you happiness, health, wisdom and auspiciousness!

In fact, the human brain can only make decisions among all known things. You cannot imagine something that does not exist in the world. For example, you imagine a non-existent creature with three heads, such as Quito, but Quito. The image of La is also a piece of existing biological images. It has a head, a tail, facial features and skin. Any detail is known to exist. For congenital blind people, their brains are no different from ordinary people, but there is no difference. The way to know the true appearance of most things, the shape may be perceivable by touching, but the color is unimaginable to them. It is analogous to a von Neumann computer. The program is given an algorithm, and given some data, it can proceed. Calculation and decision-making, but its algorithm can only be limited to a certain range. If it wants to continue learning, it must enter new data. For example, if you don’t define a color for the computer at the beginning, the computer cannot know what. It is the color human brain is essentially an advanced neural network computer. It comes with a set of advanced programs, and continuously obtains data through the five-senses system after birth, and continuously optimizes and improves the algorithm and decision-making ability. Now let’s see if consciousness is free. The question actually becomes what is consciousness? What is freedom? Because no one can give an accurate definition of consciousness, and there is no way to accurately define free will. Therefore, this question is essentially a word game. If you want to think further, it is recommended to watch Western World, the ultimate of this show. The theme is that William, one of the protagonists of free will, has been thinking about 3 seasons or a whole life, and still can’t determine whether he has free will. In the end, he no longer hesitates. Since there is no way to confirm it anyway, then go to him.

The key to determinism is not whether the human brain is composed of particles and whether it obeys the laws of physics. The key to it is the decision on the formation of human consciousness. For example, the material environment you have been in contact with since childhood has ubiquitously affected your entire ideology, including character, thoughts, and emotions. A person slowly forms self-consciousness from an unconscious baby state to finally form a complete character and will. This process is all under the exchange of information with the material world. For example, when you were young, you were exposed to a lot of water, such as rivers and lakes. Then you will have a corresponding degree of water experience when you grow up. Such as degree of fear, degree of affection, etc. This deterministic tracing method can be as detailed as the size, quality, and shape of a stone, the time, place, and sequence of appearance, and can even be as fine as the molecular and atomic level. Directly exchange information between the material world and your consciousness, and calculate the state of your entire consciousness bit by bit, to ensure that every particle that appears in your life finds a one-to-one correspondence in your consciousness. relationship. This is the true meaning of determinism. The particles of the brain are only a small part of them. Of course, in this process, it is still affected by the ideology of others, but the ideology of this “other” can also be traced back. When everyone goes back to the end, only the influence of the material world remains. Except for the very mainstream cultural consciousness, the humanistic influence is minimal. Human influences also have relatively crude material environmental traceability methods. So it is actually difficult to refute determinism. We can only look for arguments at the quantum level.
