What on earth are you guys talking about? Truth and falsity have got 
nothing to do with the openness or closedness of the world, and 
nothing much to do with activity or processes.

PS. Also, by the way: negation is not a relation; to negate a 
relation is not to invert it; 'open world' negation is exactly the 
same as any other negation; and encoding is not the same as 
representing.  And no, I am not going to explain why. Go read a book.
