You seem to be missing the point here. That is an 
epistemological question. Chris just said, he 
considers those questions irrelevant. To ask one 
of them in response is like quoting the bible to 
refute an atheist.    (02)

Why are you so sure this will happen? Take for 
example an accounting system which conforms to 
the Sarbanes-Oxley act in part by using an 
ontology which describes the terms used in that 
legislation. Why could such an ontology not 
simply be correct? Why must it be wrong in 
task-relevant ways?    (04)
