Hmm. That wasn't the line of reasoning I was expecting. And I tend to 
think of 'prescriptive' as some sort of contrary to 'advisive' (which 
is a word I made up :)).

So, what sort of prescriptions and/or advice do you think we should 
give?

Sample prescription:
	Do not have effects that are complementary to the entailments of your 
KB. (Similarly, don't have entailments of your KB that are 
complementsOf some effects.)

(Advising version:
	Effects which are the complement of some entailment of the KB may 
result in counterintuitive situations. [Insert example where an axiom 
entails, say, that you always have such and such a credit card, but 
some service has an effect that the card is canceled. This isn't 
*incoherent*, but it may be a bit surprising.])

I guess it wasn't clear, but if we're not just letting chips fall as 
they may, I would like some feedback on what we should say.

Cheers,
Bijan Parsia.
