Forgive me, you don't seem keen on questioning ALL your NC axioms John. Most people deep in the institutions of any profession do not. There is too much at stake personally. You could claim these have no value-ladeness I suppose. Values give meaning.

Our individual world view cast from our social conditioning comes first. Unless Douglas Adams is right and the answer to the question is 42, before we have the question.
