Sorry, I think we may be talking at cross purposes. My original post was to point out that some people seem to think that the answer ‘I don’t know’ to a question is unsatisfactory. I take a polar opposite point of view. If one doesn’t know, it’s the only mature and honest answer to give.

I don’t believe that there is a limit to knowledge per se. Only a limit to our knowledge at this moment in time and it is this lack that drives our curiosity.

Hardly at cross-purposes to say there are other kinds of limits to our knowledge besides our capacity for knowing. The means of knowing is another limit, and I would say the more significant one.

The answer "I don't know" can sometimes be honest, sometimes dishonest. The admission alone is insufficient--it sounds too much like Wolf Blitzer "all we give are the facts." What we want to know is why we don't know and whether our subsequent action is justified.
