- I agree with Ivan. If the size of the set we were selecting
- from were relevant we would have to worry about whether the
- real number 1/3 or the rational number 1/3 was intended. Or
- whether the writer was intending to identify the two, or . . .
-
- The difficulty with making sharp concepts vague is that there
- is often more than one way of doing so. All the more reason to
- stay with the sharp concept.
