Full Idea
The notion that things might actually be vague, as well as being vaguely described, is not properly intelligible.
Gist of Idea
To say reality itself is vague is not properly intelligible

A Reaction
It seems hard to disagree with this. It seems crazy that a pile of grain, or the hair on someone's head, are vague, and even quantum indeterminacies are not very well described as 'vague'. Vagueness is a very human concept.
