Thanks. This was a really informative and thoughtful post. I don't know what effect it will have on the discussion, but it has given me a lot to think about and I really appreciate your taking the time to make this contribution. I'm not really sure why Woj keeps hammering away at the choice bit, but I think observations like yours go a long way towards creating those very productive circumstances in which a beautiful theory is assaulted by a gang of brutal facts. Your return at the end, from the concrete back to the abstract, with the model of a contour map, really clicked for me as well. Very nicely done.
