But what's your experience of those states?  My experience of a state occurs not in my brain (though it may be activated there), but through my entire body, or neurology, if you'd like.  Two states would presuppose two bodily states.  And even if there were aspects of trust (relaxed muscles on one side of my face) and fear (tensed muscles on the other), doesn't that blend into one single composite state?  It's true you could look at it as two virtual states struggling for dominance, but in actuality I think you are moving shifting, over time, through many states, all of which are made of numerous elements.  Among those elements are possibly infinite relationships, but an overall aboutness of two concurrent states?  I'll just say it's an open question. best, JS
