- This is a good point, but not quite correct. The precision of a concept
- depends on the language game in which it is used - there are no absolute
- concepts, only relative ones - so on the same day you could find a perfectly
- precise use of "set" and a frustratingly imprecise usage. Or to put it another
- way, a concept is simply a pattern of usage (language + behavior). We can never
- have an independent measure of the precision of our concepts - because that would
- imply a concept of measurement that was independent (the concept of all concepts...)
