thoughts of a physicist on conciousness

 I am a physicist and I will provide solid arguments proving that consciousness cannot be

generated by the brain. Many argue that consciousness is an emergent property of the brain, but it is possible to show that such hypothesis is inconsistent with our scientific knowledges. In fact, it is possible to show that all the examples of emergent properties consists of concepts used to describe how an external object appear to our conscious mind, and not how it is. In other words, they are ideas conceived to describe or classify, according to arbitrary criteria and from an arbitrary point of view, certain processes or systems. In summary, emergent properties are intrinsically subjective, since they are based on the arbitrary choice to focus on certain aspects of a system and neglet other aspects, such as microscopic structures and processes. Here comes my first argument: arbitrariness, as well as subjectivity, implies the existence of a conscious mind, who can choose a specific point of view and arbitrary criteria. It is obvious that consciousness cannot be considered an emergent property of the physical reality, because consciousenss is a preliminary necessary condition for the existence of any emergent property. We have then a logical contradiction. Nothing which presupposes the existence of consciousness can be used to try to explain the existence of consciousness. Here comes my second argument: our scientific knowledge shows that brain processes consist of sequences of elementary physical processes; since consciousness is not a property of ordinary elementary physical processes, then a succession of such processes cannot have cosciousness as a property. In fact we can break down the process and analyze it moment by moment, and in every moment consciousness would be absent, so there would never be any consciousness during the entire sequence of elementary processes. Here comes my third argument: It must also be considered that brain processes consist of billions of sequences of elementary processes that take place in different points of the brain; if we attributed to these processes the property of consciousness, we would have to associate with the brain billions of different consciousnesses, that is billions of personalities, each with its own self-awareness and will; this contradicts our direct experience, that is, our awareness of being a single person who is able to control the voluntary movements of his own body with his own will. If cerebral processes are analyzed taking into account the laws of physics, these processes do not identify any unity; this missing unit is the necessarily non-physical element (precisely because it is missing in the brain), the element that interprets the brain processes and generates a unitary conscious state, that is the human mind. Here comes my forth argument: Consciousness is characterized by the fact that self-awareness is an immediate intuition that cannot be broken down or fragmented into simpler elements. This characteristic of consciousness of presenting itself as a unitary and non-decomposable state, not fragmented into billions of personalities, does not correspond to the quantum description of brain processes, which instead consist of billions of sequences of elementary incoherent quantum processes. From the physical point of view, the brain is not a whole, because its quantum state is not a coherent state, as in the case of entangled systems; the very fact of speaking of "brain" rather than many cells that have different quantum states, is an arbitrary choice. This is an important aspect, because, as I have said, consciousness is a necessary preliminary condition for the existence of arbitrariness. So if a system can be considered decomposable and considering it as a whole is an arbitrary choice, then it is inconsistent to hyotehsize that such system can have or generate consciousness, since consciousness is a necessary preliminary condition for the existence of any arbitrary choice. In other words, to regard consciousness as a property ofthe brain, we must first define what the brain is, and to do so we must rely only on the laws of physics, without introducing arbitrary notions extraneous to them; if this cannot be done, then it means that every property we attribute to the brain is not reducible to the laws of physics, and therefore is nonphysical. Since the interactions between the quantum particles that make up the brain are ordinary interactions, it is not actually possible to define the brain based solely on the laws of physics. The only way to define the brain is to arbitrarily establish that a certain number of particles belong to it and others do not belong to it, but such arbitrariness is not admissible. In fact, the brain is not physically separated from the other organs of the body, with which it interacts, nor is it physically isolated from the external environment, just as it is not isolated from other brains, since we can communicate with other people, and to do so we use physical means, for example acoustic waves or electromagnetic waves (light). This necessary arbitrariness in defining what the brain is is sufficient to demonstrate that consciousness is not reducible to the laws of physics. Based on these considerations, it would be completely unreasonable to assume that consciousness is generated by brain processes or is an emergent property of the brain
