MP: It is not semantic trickery to assert that a _translation_ can be possible however. This is the problem when people talk and get hot under the collar about 'identity theory'. At its simplest level it is the difference between 1PV and 3PV. 3PV observation and analysis _may_ eventually turn up with objective criteria that establish universally consistent and reliable correlation between certain brain processes and certain reported phenomenal experiences - things like itching on certain parts of the body, "hearing music", "seeing bright colours", etc. I am not sure about experiencing redness per se, although that is not ruled out. It is conceivable that this type of facility could be useful in diagnosing locked-in consciousness. The key concept of course is _correlation_. Accurately *identifying* certain characteristic brain processes - in both relevant senses of identifying - is almost certainly what the future holds for us. Is this what you mean by *reducing* the experience though? If so I think it is a 'red herring'; being able to locate and accurately describe brain processes from/in 3PV cannot thereby diminish or encompass the experience of what it is like to be that process.
