On the contrary, science can have nothing whatsoever to say on the
existence or non-existence of subjective experience, since science
rests logically on subjective experience, on awareness. Science is
built up from observation and logic, and observation *is* subjective
experience, awareness. What we call objective data are nothing more
than subjective experiences that correlate well between individuals -
i.e., subjective observations that can be replicated are objective
data. So far from being unreal, subjective awareness is a fundamental
ontological category of existence. No matter how complex the apparatus
of a scientific experiment, there is no observation until a person or
persons become aware of the output or result of that apparatus.[1]

This is why your argument about the spatiotemporal asymmetry of
subjective experience being at odds with other physical laws is
unnecessary - we never get science started without taking awareness as
axiomatic; we have QM because it is built on the logical foundation of
subjective experience. Since you don't need to/can't prove an axiom of
a logical system, you don't need to/can't prove awareness exists. Nor,
having assumed it does exist to get things rolling, can you disprove
it. At most you can show that the whole system is logically
inconsistent, but this would bring all of science down, not subjective
awareness.

[1] yes, this also includes thought-experiment robots capable of
recapitulating all of science from scratch. Their results are not
results until you or I or some other person is aware of these results.

Please see my reply to Ron for my take on awareness.

This claim is provably false. For example, about 1 person in 6 on this
planet is Roman Catholic, and all of these 1 billion+ people are
required, in order to be members of the church in good standing, to
believe in an extra-physical immortal soul capable of moral choice.
This is what they mean by free will, not some cut-down deterministic
thing.

Ah. Now I understand why you've been consistently ignoring the point I
keep making about objective reality being fundamentally quantum in
nature. It's because you really don't understand this point.
Observation is not subjective experience, it is entanglement. See:

http://www.flownet.com/ron/QM.pdf

Or David Deutsch's book "The Fabric of Reality" for a more complete
treatment.

No, you are simply flat-out wrong about this, at least from the point of
view of contemporary science. It's ironic that you, who stand so
strongly on scientific principle, should be advancing a point of view
that has been so thoroughly discredited by science. The idea that
humans have some sort of privileged status in the scheme of things, even
in the quantum mechanical scheme of things, has been discredited every
bit as thoroughly as creationism.

No, no, and no. All you need to do science is classically correlated
measurements, which includes the states of computing machines and
reports of subjective experience by humans. And classically correlated
measurements arise as a nearly exact approximation to quantum theory
when dealing with large systems of mutually entangled particles. There
is no need to get metaphysical to do science, just as there is no need
to get metaphysical to advance you political agenda.

Go read my paper, or Deutsch's book, or Eliezer Yudkowski's writings on
QM. All of these are easily accessible, and the topic is much to
complicated (to say nothing of off-topic) to recapitulate here.

Finally a topic appropriate to the lisp newsgroup :-)

Somewhat tangentially to the topic at had, do check out the book
`Phantoms in the brain'. From the back cover: `A brilliant "Sherlock
Holmes" of neuroscience reveals the strangest cases he has solved -
and the insights htey yield about human nature and the mind'

An amazing book about how our brains build a picture of ourselves and
reality - and how the brain can create a misrepresentation of our
reality, such as having three foot long noses, a table being part of
our body, etc.
