The nature of the mind, qualia, and consciousness has been a great puzzle for mankind for a long time. Fortunately, with the continuous effort in unraveling their nature with all kinds of investigations for centuries, we now have a wealth of evidence, knowledge, and concepts to resolve this great puzzle. The final key is the detailed examination of their physical properties. When this is done, the nature of these puzzling entities is finally revealed. This has been put into theorems in this theory. Its essence is as follows:
- The mind is part of the functioning brain. It is not a functionally separate entity from the brain, but it is not identical with the brain, either. (Chapter 1)
- From the physical properties of the mind and of the information-processing processes of the brain, it can be proved that the mind is the information-processing processes of the brain. To explain the phenomenon of the mind, therefore, a novel entity is not needed; only the correct point of view to see the unobvious part of the obvious entity is. (Chapter 2) … Because the mind is an information-processing entity, it is an informational entity, not a conventional physical entity (or mechanical entity) like mass, energy, or force. That is why it is so different from the conventional physical entities. (Chapter 2)
- Qualia or mental phenomena that we can consciously experience in our mind, such as the vision of a house, the sound of a song, and the odor of a rose in our mind, are neural-process associated physical phenomena. They are governed by physical laws and are physically predictable. (Chapter 4)
- From the physical properties of qualia and of special kinds of neural process signaling patterns, it can be proved that qualia are special kinds of neural process signaling patterns. To explain the phenomena of qualia, no novel entities are needed. Qualia are just under-recognized parts (the signaling-pattern parts or the informational parts) of the well-recognized physical entities (the neural processes). (Chapter 5) … Because neural process signaling patterns are neural process information, qualia are special kinds of neural process information. Like the mind, they are informational entities. (Chapter 5)
- From the physical properties of consciousness and of a special kind of reentrant signaling state, it can be proved that consciousness is a special kind of reentrant signaling state: it is the composite of all special reentrant signaling states. … Because a neural process signaling state is the neural process information, consciousness is a special kind of neural process information. Like the mind and qualia, consciousness is an informational entity. (Chapter 6)
- Because a neural process that performs a certain function without qualia occurring and a neural process that performs the same function with qualia occurring have different information in the processes, they require different signaling patterns. Therefore, they have different physical effects on other neural processes, at least from the different effects of different signaling patterns. Qualia thus have physical effects. In addition, because qualia induce the consciousness neural process to create conscious awareness and experiences of the qualia and because the consciousness neural process is a physical process, qualia cause changes in a physical process and thus have physical effects. It can be proved similarly that consciousness (conscious awareness and experiences) has physical effects. (Chapter 5 & Chapter 6)
- The fact that qualia and conscious awareness and experiences of the qualia occur in only the final-stage sensory perception and the highest-level cognitive and executive neural processes, which are the latest-evolved neural processes, and never occur in more primitive neural processes, such as the brainstem, cerebellum, and basal ganglia, indicates that they are results of nervous system evolution. (Chapter 5 & Chapter 6)
- The fact that it took more than two billion years after life had appeared on earth and hundreds of millions of years after the nervous system had developed before neural processes that were advanced enough to create qualia and consciousness could emerge into existence also means that qualia and consciousness came into existence because of no other cause than evolution. (Chapter 5 & Chapter 6)
- The fact that qualia and consciousness still exist today indicates that they have been selected to remain in the evolutionary process. This means that they must have helped increase the chance of survival of animals that have them. Qualia and consciousness thus are the evolved functions to help increase the chance of survival of animals, including humans, that have them. (Chapter 5 & Chapter 6)
- Because identical neural processes have identical mental processes and identical qualia, different qualia are not physically possible. (Chapter 7 & Chapter 9) Also, beings that have identical neural processes to humans’ must have identical mental processes and identical qualia to humans’ – this negates the physical existence of p-zombies (philosophical zombies). (Chapter 7 & Chapter 10)
- Different neural processes have different mental processes and different qualia. Identical mental processes and identical qualia require identical neural processes. Different mental processes and different qualia require different neural processes. (Chapter 7)
- Mental interactions are physical processes. (Chapter 8)
It is fundamental in the nature of this universe that it consists of two inseparable and complementary parts – the mechanical part and the informational part, and it is fundamental in the nature of this universe that there exist the mind, mental processes, qualia, and consciousness (conscious awareness and conscious experiences) in the informational part, that the mind and mental processes exist in the information-processing processes of neural processes, that qualia exist in the special signaling patterns of neural processes, and that consciousness exists in the composite of all special reentrant signaling states. And because of these fundamentals, we exist.
This Theory is just a basic theory that deals with basic concepts of the nature of the mind, qualia, and consciousness. It is a mere one step in understanding this great puzzle. There is still a lot of problems to be solved to understand it completely. For example:
Technical problems – What are the exact characteristics of neural circuits and neural processes that can create qualia? What are the exact characteristics of signaling patterns that are qualia? What are the exact characteristics of a neural circuit and neural process that can create consciousness (conscious awareness and experiences)? What are the exact characteristics of signaling states that are consciousness (conscious awareness and experiences)? How do neural processes encode information in their signaling patterns and signaling states to be qualia, conscious awareness, and conscious experiences of colors, sounds, thoughts, emotions, volitional motor controls, etc.?
Fundamental problems – How do neural processes learn to read the meaning of information of the signaling patterns and signaling states? Is this ability inherent in their nature without having to learn from experiences or is it experience-induced? From the basic properties of signaling patterns and signaling states, can we predict the characteristics of signaling patterns and signaling states that are qualia and consciousness? Does signaling in other systems, such as electronic systems, have the ability to be qualia and consciousness? Is this theory, in fact, applicable to not only animals with a nervous system but also every system that processes signals or information? As all physical interactions of all things can be viewed as the processing of information of those things, are all physical interactions basically kinds of information processing? If so, is the kind of entity that is us (the mind, qualia, and consciousness) inherent in all physical interactions and thus actually pervading this universe entirely since the beginning of this universe, with us just an evolved complex form of it?
Thus, there is a lot of questions that this theory does not address. However, the author hopes that this theory, even if it is not complete and even if it may prove to be flawed, creates some new concepts and offers some new directions in investigating this great matter of our lives and helps advance the understanding of this important problem in science.
The author would like to thank Naruepol (https://www.facebook.com/Artbigstudio/) who helped draw many illustrations in this theory.
Also, the author is grateful to PubMed (https://www.ncbi.nlm.nih.gov/pubmed), which has been the important source of a lot of valuable publications, to various informative websites on the internet, and to all the authors who have published their works that I have used as resources and references.
Finally, this Theory would not have been finished without the internet and search engines, so I feel much obliged to those who created these beneficial instruments for mankind and me.

In the end, it can be concluded that we are just information-processing entities on the informational side of the universe.
We are here because it is basically possible to have us in this universe and because we help increase the chance of our own survival
… and our own species.
You are here to help increase the chance of your own survival
… and your own species.
