 But does it really amount to the same thing?  With TRUE/FALSE, you can say
"I definitely know that Fred is NOT a ChocolateLover" (poor Fred, what he's
missing!).  Without it, you have to infer "I can't find anything that says
that Fred IS a ChocolateLover, so he must not be one".

Isn't this this similar to the existential stataus of a bnode, whose
existence has to be inferred because it is connected to other nodes?  Most
people are saying that there really is a difference between such a node and
an identified resource.  So how is it that inferring FALSE is suppsed to be
the same as asserting it?
