You are saying that the beings running our simulation may
be able to detect that we are self-aware, but that they
wouldn't necessarily equate it to their own self-awareness?
Why not? How many different kinds of self-awareness are
there? I see that you have no difficulty supposing that
the characters in your dreams and in books have your kind
of self-awareness.

Of course they haven't empowered us to operate avatars
within their own environment, or it would be all over
the newspapers.

So? If MPS is a fraud, then we have exactly zero indication
that a conscious human can host more than one person. An even
stronger argument is that it would have been very costly for
evolution to have endowed us with that capability.

We come right back to this statement that has bugged more people
than just me. Doesn't it sound a little high falutin' to claim
that one's brain generates a universe? A whole universe? Or
only a *few* galaxies and quasars? Do cats' brains also generate
universes? You lose me when you talk like this.

Let me try to get a grip on this. Suppose that we go to
a sleep clinic, and carefully monitor a patient as he
enters into the five levels of sleep. I am certain that
no instruments would detect a mass increase, so your
"universe" must only be a metaphor. Okay, so there is
all sorts of weird electrical activity going on that we
don't exactly know the purpose of. Presumably, the rest
that the tired brain is getting contributes to waking
survival. Some parts of the brain during REM evidently
try to piece together the random inputs their getting
into a believable interpretation, and so we get fragments
of images, ideas, and audio that we even can remember.
This sounds *awfully* thin to describe the way that you
like to. We should, instead, view the reposing patient
as undergoing various hallucinations and delusions, and
to not be actually entirely conscious at all.

Consciousness is evolution's answer to how to generate animal
behavior most in accord with survival: it was found that giving
the brain access to recent memory in such a manner that current
activity could be deeply affected afforded much better survival
chances.

In dreams, we for the most part project consciousness on to the
images and voices of people that we imagine, much like we project
such consciousness onto other people in real life, even though
we don't, of course, actually generate that consciousness. So
in a dream we suddenly imagine that we hear someone say something,
and we don't for some amazing reason remember our own contriving
of that statement. It still seems like a leap to project a full-
blown consciousness onto people we think we see and hear in
dreams.

I'm suggesting that we have no evidence whatsoever that
there even is any universe but ours.

Yes, someday when we mount full blown simulations, we may
be able to judge with a lot of evidence that it hosts
self-aware creatures. But that's only because we are
going to, unlike nature ever has, invest huge amounts
of resources to create such simulations. Likewise, if
we are living in a simulation, you can bet that the
originators sunk a lot of bucks into it.
