Maybe a historian on the net can describe studies showing that before the age
of biological classification people didn't use the word "bird" to refer to a
class of animals.  Once biologists decided what a bird was, viola!  everyone
started to use this wonderful new catagory in their conversations.  I'm just
waiting for sociologists to define the catagory "friend," so that I can invite
some friends to lunch.

The point behind the sarcasm is that formal classifications decided by people
may mirror the classifications that people use, but are a completely different
phenomenon.  Just because biologists have an "easy" classification of animals
doesn't mean that the catagories that our minds use are the same, or that the
process of classification is the same.

Lakoff discusses this in detail in his book (WF&DT), and describes studies
that show the similarities and differences between formal and cognitive
catagories.

I know this has absolutely nothing to do with AI, but this article looks
STRANGELY FAMILIAR - I seem to remember seeing this posted at least 3 times
already!

Is anyone else experiencing the same thing?  If so, could Mr Kendall please
check with his local gurus if there are any problems with posting from his
site?
