Take a statement like:

(1) I am tall.

Assume this statement is .7 true. How true is it that this statement is .7
true? Well, that's fuzzy too, contrary to what you seem to be suggesting.

Not so. There are two extremes to the distinction, but the
evalation of the distinction need not fall on the extreme ends {0, 1}.

Come again?
