EY:
How do logicians deal with the durational aspects
of an attribute? Cats do not purr all the time, so
aren't qualifiers necessary?
e.g.
All cats purr sometimes
This is a cat
This cat purrs sometimes
OR
Male kittens become male cats gradually
Un-neutered male cats spray
This is a male kitten which will not be neutered
Eventually this kitten will become a cat and spray.
OR
Most things with wings can fly.
If a cat had wings,
most likely it could catch birds on the fly
and be happier and fatter.
Unless the sun turned supernova first,
Then cat wings would taste good with BarBQ sauce,
since wings are best with BarBQ sauce or spicy salt mixtures.
