Michael S. Gazzaniga, "The Consciousness Instinct: Unraveling
The mystery Of How The Brain Makes The Mind" (2018)
Pattee, who has been a keen observer of human thought,
feels that philosophers have approached the mind/brain divide
from the wrong end of evolution. (p 176)
Howard Pattee doesn't concern himself with the gap between
the material brain and the immaterial mind.... The gap between
living and non-living is at the root of the gap between the mind
and the brain and offers a framework for addressing
the mind/brain problem.
Pattee argues that living matter is distinguished from
non-living matter by its ability to replicate and
to evolve over the course of time.
Life did not just make more life. Life could increase in complexity;
it could evolve.... He[Von Neumann] concluded that it needed
a symbolic self-description, a genotype, a physical structure
independent of the structure it was describing, the phenotype.
He correctly predicted how cells actually replicate before
Watson and Crick did.... He did not address the physical
requirements for implementing his logic....
Pattee took up the challenge.
There must be a physical manifestation of von Neumann's
symbols. What Pattee calls the physics of symbols produces
certain problems.... Any living thing that "records" information
is introducing a form of subjectivity into the system.
The second problem is the relationship between the genotype
and the phenotype. For example, when we consider DNA, the
genotype is the DNA sequence that contains instructions for the
living organism. The phenotype is the observable characteristics
of an organism, such as its anatomy, biochemistry,
physiology, and behavior. The genotype interacts
with the environment to produce the phenotype.
For one, the genotype is non-dynamic ... on the other hand,
the phenotype ... is dynamic and uses energy.
[I]t was from the control interface between these two layers
that the epistemic cut [the unavoidable conceptual separation
of the symbolic record of an event and the event itself] arose.
Pattee extended von Neumann's logic by contending that
the symbol themselves, which make up instructions (the
hereditary record), must have a material structure and that
the material structure, during the phenotype construction
process (the building of the new automaton), constrains
the process in a way that follows newton's laws.
In one life, symbols are made of physical material (DNA is ...)
that follows Newton's laws.... However, in the other life,
as repositories of information, the symbols ignore these laws.
The implication is that the gap between subjective conscious
experience and the objective neural firings of our physical
brains, those two modes of descriptions, may be bridged
by a similar set of processes,, and it could even be
possible that they are occurring inside cells. (p 194)
[E]ach mental event is managed by brain modules that
possess the capacity to make us conscious of the results
of their processing. The results bubble up from various
modules like bubbles in a boiling pot of water. Bubble after
bubble, each the end result of a module's or a group of
modules' processing, pops up and bursts forth for a moment,
only to be replaced by others in a constant dynamic motion.
Rebecca Saxe, at MIT. has discovered ... that there is a
special human brain hardware in the right half brain that
appears specialized for determining what the
intentions of another person might be.
[T]he left brain, which benefits from modules that
enable abstract thinking, verbal coding, and much more,
does not have the module to take into account
the intentions of others. (p 212)
In the end, we must realize that consciousness is an
instinct. Consciousness is part of organismic life.
We never have to learn how to produce it or
how to utilize it. (p 237)
