Hard problem of consciousness is described in Wikipedia.
It is also described in the article
by Chris King.
Well, luckily
I am not mathematician and very proud of it because mathematicians used to
expose their minds/brains to extremely puzzling questions and problems. The extremity
of puzzling can be so huge that the minds/brains can collapse
as wave-functions. Some examples:
Subjective consciousness may be necessary
for the actualization of physical reality, and thus fundamental to physical
existence in a cosmological sense, as expressed in the anthropic cosmological
principle that observers are significant and possibly
necessary boundary conditions for the existence of the universe (Barrow and
Tipler 1988).
Not bad,
right?
It is a psychological fact that we believe
we have the ability to control and modify our actions by the exercise of will,
and in practical life all sane men will assume they have this ability
(Hooper and Teresi 1986). However this premise, which is basic to all human
action, contradicts physical determinism, because any action of mind on brain
contradicts the brain functioning as a deterministic computational machine, in
its own right, in the physical world.
A confluence between quantum physics and
the science of mind may resolve this apparent paradox. Firstly physics has
difficulty determining when collapse of the wave function from a set of
probabilities into an actual choice takes place, leading to some
interpretations in which the conscious observer collapses the wave function.
Secondly quantum uncertainty and non-locality provide exactly the types of
explanation which could enable the subjective experience of free-will to be consistent
with a non-deterministic model of brain function. The unpredictability of chaos
(Stewart, Schuster) due to its amplification of arbitrarily small fluctuations
in what is known as sensitive dependence on initial conditions,
could provide a means to link quantum indeterminacy to global brain states.
I am done…
but let’s continue:
Some physicists think the wave function
never collapses
- all the possibilities happen and there is a probability universe for each
case. This is the many-worlds interpretation of Hugh Everett III. The universe
then becomes a superabundant superimposed set of all possible probability
futures, and indeed all pasts as well, in a smeared out holographic
multi-verse in which everything happens. It suffers from a key difficulty. All
the experience we have suggests just one possibility is chosen in each
situation - the one we actually experience. Some scientists thus think collapse
depends on a conscious observer. Many worlds defenders claim an observer wouldn’t
see the probability branching because they too would be split but this leaves
us either with infinite split consciousness, or all we lose all forms of
decision-making process, all forms of historicity in which there is a distinct
line of history, in which watershed events do actually occur, and the role of
memory in representing it.
Well, it’s
enough for today… I need a vacation to
get rid of this article.
I think I
understand pharmacology, chemistry, medicine, and some aspects of biology
pretty well but not in the same extent as Chris King does the mind-breaking
definitions! Respect!
