Sloppy me. Yes you are right. Gazzumpt by the language again.
I was actually going to quote Ramachandran. Glad you did, for the rest of the 
list... there's a didactic role here...

Back to the measurement thing, just to be very clear.... 

The _event_ of the expression of the experiential quality in the brain is 
directly causally connected to the act of measurement(peripheral sensory 
neurons behaving appropriately). The experience itself (the detail of the 
quality thereof) could be anything (you could make sensing heat a sound if you 
wanted - synthesthesia, Ramachandran again). Exactly what experiential quality 
is selected for representation of hotness will be something for future 
biophysics to work out. My 'hot' and you 'hot' could be different. 

In terms of brain operation as long as the resultant behaviour is appropriate 
and consistently used the quality of the experience is irrelevant.

The result is that an assumption that one can necessarily claim similarity of 
the physics of the real world and the brain physics of the behind experience is 
simply not justified. This does not mean that the physics of the distal world 
is not in some conformally mapped/useful way _similar_ to the physics of the 
experience. It just means that you cannot assume that the relationship.

Exactly what 'ism this is I don’t know. Indirect realism? It doesn’t matter 
much. Naïve realism is out. The philosophers of perception can retrofit the 
actual nomenclature situation after it’s sorted out by the biophysicists.

I think this encapsulates the position.

I declare you the winner of today's grumpy old guy contest.. :-)
