Like many other children, when I was a child, I wondered about many things, especially the universe. Does this universe have a boundary, or is it boundless? If the boundary exists, what does it look like, and what is beyond it? If not, how can the universe go on infinitely? Are the space and time continuous or composed of very thin slices in succession? If so, how thin is each slice? How did the universe begin, and what was it like before that? When it ends, what will it be like after that? And many other questions. I dreamt of being a scientist in physics or astronomy to learn more about these matters and find more answers. However, because of various family and social factors, I did not become a scientist but came to be a doctor and, finally, a neurologist instead.

That was not a wrong choice because it finally helped me answer the deep, non-physical questions I have always had in my mind also since I was a child: What is the mind? What are these experiential phenomena—visions, sounds, smells, etc.—I experience every day in my mind? Do other people experience them—see them, hear them, smell them, etc.—as I do? Or is what they experience in their minds different? Why can’t there be just the mind without them? Of what uses are they? How can the universe this vast exist and transpire as I experience it in the brain this small? And many other questions, including the most important ones: What am I, and why do I exist?

During more than 37 years of my clinical practice, I have seen tens of thousands of neurological and psychiatric patients with various disorders in perception, motor function, behavior, mood, consciousness, etc. I have seen patients ranging from perfectly calm to dangerously delirious to deeply comatose, from very brilliant to severely demented, and from in perfect health to at death’s door; some even passed through it temporarily, but some, forever. I have had the chance to treat them with my own hands, some with success but some with failure. I have seen them change with my own eyes, some for the better but some for the worse. Bit by bit and year after year, I have learned and got clues from these encounters. Finally, all these experiences have given me the key to the nature of the mind and its phenomena—qualia, consciousness, and others—and enabled me to write this theory.

“Since I was a child, I have always wondered …

what I am, why there has to be me, and why there have to be

such experiential phenomena as the red color, the happy emotion,

and the feeling of what it is like to be me in my mind …

The answers had eluded me all along.

Finally, after being puzzled for a very long time …

Thirty-seven years of seeing neurological and psychiatric patients

has given me the key to unravel these mysteries.”
