Hi Lee,

I am not sure this is the reply you mentioned in the
previous post. If so I guess you decided to make it
public. That is alright with me too.

We are using the term *explain* in different ways.

Look, would you have disagreed (were you living in 1800)
with the Marquis Pierre Simon de LaPlace when he would
assert that Newton's theory of gravity explained all
celestial movements?

I guess so! YOU probably would have said, "Mais non,
it does not explain how an influence can instantaneously
reach out through space. It does not even explain what
gravity *is*!" (And by the way, no fair using Mercury's
orbit, the details of which were not discovered at that
time.)

LaPlace would have looked down his nose at you and replied
that "the *theory* explains the movements, you fool. C'est
facile de voir that you, Monsieur, wish to know what explains
the theory. I have no need of your hypothesis, or of you."

So likewise, I will say to you, we cannot explain quantum
mechanics, but QUANTUM MECHANICS DELIVERS AN UNPRECEDENTED
FIFTEEN DECIMAL PLACES OF ACCURACY and so explains incredibly
perfectly the result of our laboratory experiments!

[GK]
Far from me to disagree with you, or Laplace! QM produces indeed
the most impressive numerical predictions of any theory ever conceived
by humans!

[LC]
YOU seem to want an explanation of (or a satisfactory interpretation
of) the *theory*. The theory does not provide that! No theory---
not Newton's, not Einstein's, and not QM, can do that, can explain
*itself*.

[GK]
Not exactly, and I have not expressed such demands of QM in any
of my statements. What I stated, and you have not denied that yet,
is that QM does not give me or you a picture (much less an explanation)
of the world as we know it, with somewhat reliable objects placed at
definite position at definite times. This is a fact, not a demand on
my part on the theory. Most people who feel unhappy about this
state-of-affairs don't blame it on the theory (as they did 3 generations
ago) but blame it on themselves or on us, humans, who have not
interpreted the theory correctly yet.

Many worlds of course. Have you or have you not read "Fabric
of Reality" by David Deutsch?

[GK]
Oh yes. But I am not a convert.

[LC]
As for a number on my "naive reality"... For Christ's sake,
I give up with you. You are hopeless. You are probably one
of those people who calls "fascist" everyone who has political
disagreements with you, whether or not they themselves adopt
the term.

[GK]
(...I'll pass on this one!)

[LC]
I give up. I hereby grant permission for the incredible
Godfrey Kurt Lee to call me a "naive realist" --- but him
only! Nobody else better try it!

Lee

[GK]
Wow!! Actually my name is Godfrey Kurtz. Lee is a bad nickname
that I had to use to get a username from AOL. No pun intended.
(I hesitate to call you anything, at this stage! )


P.S. I will reply to the rest of your post when I am less
exercised :-)

[GK]
Now that Bruno promoted me to a machine I feel like telling
you, like good all HAL 5000: "Why don't you take a pill and
lay down?" (:-)

Get well soon,

Godfrey
