No, certainty is neither here nor there; it is "truthishness" that's
at stake. A better way to view it is to map all talk of truth into
talk of set membership: a car is blue iff it belongs to the set of blue
things. Now we can understand a fuzzy-logic claim that "the car is blue"
being 90% true by mapping it to a fuzzy-set-theory claim that the car
90% belongs to the set of blue things.
Certainly the numerical intensity of the blueness is irrelevant, you're
right about that.
