True, but I suspect that an argument about epistemology, and concluding that we can't 'know' anything, wouldn't be helpful in an arguement about say, global warming, would it?
Of course it can; It would help both sides of the argument to conclude that they have no knowledge. Would that be accepted by all the most obvious conclusion would be: Always better to prevent than having to cure.
Would make these discussions as simple as you can get, no?
salaam.
