It depends what your definition is (this is why I don't use the word mind,
nor consciousness, nor similiar portmanteaus). Would you agree that a mind
is a physical process, which happens to process information? So you only
have to look at those relevant aspects of the physical system engaged
in the abovementioned process, and can abstract away anything else?

Are you sure that you're always getting of what other people are saying?
No offense, but you were still arguing with yourself when I unsubscribed,
and you don't seem to have made any progress since.

I don't see why you would invoke Planck timescale for what happens in the brain,
unless for a gedanken (which is always dangerous, because people will take you literally).
Not much relevent happens in the brain significantly under 1 ms time scale, and subjectively 
the biochronon is at 50 ms, or larger, depending on how complex stimulus processing
is.

Now you're picking some arbitrarily single characteristic of a physical process,
and declare it to be the only thing what matters. On basis of which evidence?
Declaring that mind is energy is about as meaningfull as declaring that mind is
information. Or that the mind is a future predictor. None of it is completely
wrong, but perhaps the blind men shouldn let go of the nose hairs of the trunk,
and look at the whole animal.

Huh?

Or maybe just an illusion of a new insight. You sound awfully sure, and awfully
confused at the same time, this time. Are you realy sure you're making any progress 
when you're switching point of views? For an external observer, it looks
like a random walk in concept space.

If you model the mind as a physical process, there's not much you can reexamine
without leaving the domain of science.

You sound like a psychologist. This won't lead you anywhere. You need to be
at least psychophysics-level tall to ride this ride.

There's no need to get lost on the metalayer meanderings, when the issues are
completely treatable with good old science and technology.

What is death? You better define it first, because most people don't know what
death is. (Death being irreversible is quite true, because it's the definition of
death -- irreversible loss of knowledge about a particular physical process).
