Gee, i don't agree with this definition of belief... in particular
i think belief comes in when knowledge is uncertain but _not_ 
unknowable.  Todays uncertainties are tommorrows textbook facts.
But maybe this is splitting hairs...

I feel more comfortable with the word agnostic myself.  If implies the
type of uncertainty any belief on this topic already has, thus some may
find it redundant and weak.  I also think the word heathen is quite
descriptive (altho lacking in completeness)... in particular it can be
useful when discussing religion with a 'believer'.
