These are excerpts and elaborations from my book "The Nature of Consciousness"

A Reductionist Theory of the
Self The "i" is the
central problem of consciousness. Even if we eventually explain how conscious
experience arises from the electrochemical processes of the brain, even if we
discovered some kind of "proto-consciousness" that gets combined to
form emotions and feelings, we will still need to show how and why that set of
emotions and feelings becomes an "i". That matter can feel
emotions is mystery enough. But what we feel is even stranger: it is not that
each part of our body, each molecule feels emotions. It is "i" who
feels those emotions. A body is made of parts that
interact, and each one has its own life.
But a consciousness is an "i" that feels all of the emotions
related to that body. My consciousness is not distributed the same way that
matter is distributed in my body. Let us assume that
everything is conscious to some degree. Every atom, every molecule, every
tissue, every organ, every being is "conscious". And that "i" is just what i am
conscious of. If i were born a finger,
i would only be conscious of what a finger does. "I" happen to be born the part of the brain that is
conscious of what i am conscious. In this scenario of multiple
consciousnesses, the "i" that is writing this sentence is not the
conscious part of the foot or the nail, it is the conscious part of a part of
the brain. I am not conscious of my
foot's consciousness, because "i" am the consciousness of something
else (a part of the brain). And i am not conscious of
the consciousness of any other parts of the brain because "i" (the
one who is writing right now) am not those parts. "I" am the
consciousness of a part of the brain, and it turns out that "i" (this
particular consciousness) receive information from several parts of the body
and direct order to several parts of the body. For example, it is likely that
the "consciousnesses" associated with my fingers are conscious of
typing on the keyboard. They have to, because the brain tells them to.
"I" (the consciousness of that part of the brain) am only aware of
sending them the order to type. Because
of the organization of the body, the brain controls other organs. Because each part is associated with a
consciousness, each part is aware of what it is doing. But "i", the
consciousness associated with this part of the brain, identify with the whole
body. "I" am actually
not conscious of everything. There is a consciousness associated with my liver
and one with my intestine and one with each of millions of minuscule parts.
"I" am not aware of any of those parts. I cannot feel that i because
"i" am not that i Evolution has decreed which
parts are connected to the part of the brain that is associated with
"i". "I" am aware only of those parts. The main difference between "i"
and other "consciousnesses" inside this body is that "i"
(or the brain part associated with that "i") can tell fingers to type
this sentence, and can tell the mouth to utter words. Of course, there could be
another consciousness (another i) that is conscious of parts of my body that i
am not conscious of. Maybe there is a consciousness (another i) that is
directing me to think what i am thinking and directing me to direct the fingers
to type what they are typing. I cannot be conscious of this
"super-consciousness" or of any other consciousness associated with
my body, because "i" am not it or them. The reason things do not get
out of control is that the structure of "consciousnesses" must mirror
the structure of the body, so that an order issued by a consciousness cannot
conflict with the order issued by another consciousness. Finally, in this scenario of
multiple consciousnesses, it is not necessary that "consciousnesses"
be truly directing anything. Each
consciousness could simply be the "phenomenal" aspect of a physical
process: any action by a body part also yields a conscious experience that
presumes being the cause of that action.
Whether it is consciousness that directs the body or viceversa is
another issue. The body is made of parts,
each part being made of parts and so forth all the way down to elementary
particles. Each of those parts, all the
way down to elementary particles, also has a phenomenal aspect, i.e. its own
"consciousness". The consciousness that is
writing this sentence is "i". There are countless consciousnesses
that share this body, each of them conscious of what one part of the body is
doing. They may all be convinced of having free will, just like I am. There may
be consciousnesses that share this body and direct "i" to do what
"i" am doing. In this scenario,
"i" cannot feel any other consciousness than "i", because
that is what "i" am. Back to the beginning of the chapter "A Physics Of Consciousness" | Back to the index of all chapters |
