Dear Terry,
I have taken a quote from your post: "You cannot look at external reality (external world) and prove the truth [about] what an individual is feeling (subjective world)".
Poets, according to T S Eliot, aim to produce, through language, what he calls "object correlatives" for emotions (subjective states) that a poet wishes to have occur in readers. That is, a poet is not interested in expressing an emotion (such as "I feel hurt my girlfriend dumped me"; what a poet is interested in is producing the aesthetic feeling of "hurt" in a reader via the affects produced by a reader giving their consciousness over to the external object (objective correlative).
We can readily see how such a model might help account for the relationship between an object designer, the objects that they make, and a person who experiences such made objects (hence aesthetic).
So, what this suggests is that we can look at an object (made object - external reality - for example, a poo the performance artist did on the floor) and predict that an adult person will feel revulsion (subjective state).
Following this model we can pretty soon predict, with a high degree of regularity, how people will subjectively experience language objects which are firstly in the external world and then secondly in an internal world (as neurological events) and thirdly caught up in a subjective affective state.
The fact that we can NOT determine a truth about this, absolutely, beyond YES they have received the message or NO they have not received the message, is pretty dull stuff. We are mostly rightly interested in everything that happens after YES.
cheers
keith

Dear Jurgen and all,
For testing theory, I've found Popper's 'three incommensurate worlds' model useful (Popper 1976).
It gives some clear and precise boundaries and insights.
Most people think of 'falsification' as the mainstay of Popper. His 'Three Incommensurate Worlds' model is what locates that understanding about the role of falsification, and provides the real value of Popper's work in understanding 'testing' and the devising of tests for validity.
Put simply, Popper argues reality can be separated into three incommensurate worlds:
1. The world of subjective and subjective experiences
2. The world of theory
3. The world of the external and objective
The significant issue is these are incommensurate. This needs saying again - the three worlds are *incommensurate*, i.e completely and totally independent.
The implication is you cannot prove the truth of anything in one world using observations from the other worlds. In an essential way, they are not causally linked.
In each, proof is only valid within its own world.
For example, in the limit,
You cannot look at external reality (external world) and prove the truth what an individual is feeling (subjective world)
