Nice article, but I have a very pedantic nitpick. The article should really be about ambiguity as opposed to vagueness. In general, we (i.e. philosophers of language, and I assume linguists) think of ambiguity as being about uncertainty of meaning, and vagueness as being about uncertainty regarding the state of affairs which make a statement true or false.

A question like “is there a limit to the fullness of emptiness?” is ambiguous because it’s not clear what question the speaker is trying to ask. By contrast a vague question like “how many grains of sand make a heap of sand?” is vague because it’s not clear what x amount of grains would qualify.

But notice the latter statement is non-ambiguous as it were. We know precisely what the speaker is asking, and that they want an answer of the form “x grains make a heap of sand”; we just don’t know what that x is because there are borderline cases that could constitute a heap.

But in the ambiguous example, it’s just not clear what even could satisfy the speakers question, since the meaning is indeterminate.

There is a wonderful parody of wanna be deep thinkers in the beginning of Jack Kerouac's On the Road. Characters staying up all night "discussing" philosophical ideas by throwing out lines from the books they are reading without really understanding anything. Or so I presume.
