This has all sorts of problems, and makes all kinds of dubious assumptions.
First of all, the use of the word sensation is quite ambiguous.  Do you mean
the signals sent to the brain?  In that case, the definition will not do,
since several brain processes produce "blueness" from inside the brain.  Or
do you mean the brain state itself?  This assumes that blue-state is
isolable from other sensations which are also evoked by those wavelengths.
The emotional content of color is well known, and easily destinguished on a
subjective level from the color itself; but there's no guarantee that this
division manifiests itself at a lower level.  There's also the problem
(again) that these sensations can be stimulated without visual input at all,
such as in dreams or recollections.  It's possible that Rich's definition
may be useful, but it must be demonstrated to be true first.

Well, in fact Occam's Razor denies BOTH of the statements, as I said before.
If I had originally posited the non-existence of the blue car, this
introduces an unnecessary complication, without evidence; so the situation
is in fact exactly symmetrical.  Without evidence, the only correct
hypothesis is "we know nothing about what's in the parking lot."  Only this
statement minimizes the entities.  However, on to Rich...

If you truly believed in the applicability of Occam's Razor, you would be an
agnostic, not an atheist.  Positing the non-existence of God at this point
explains nothing, and adds an unnecessary entity.

Obviously Rich has run out of arguments again, since he is once again
speculating on my mental state.  Rich, do you think you could try to argue
SOMETHING on its merits just once, instead of dragging in all manner of
irrelevant and groundless "facts" about my the other side believes what they
do?  Such arguing is grossly unscientific, and if your points were strong,
you wouldn't need to engage it such obvious attempts to get off the subject.
