I'm looking for the source of the von Mises quote comparing numerical economic measurement to studying the pyramid of Cheops or something like that. I can't find any leads in the index of Human Action, and I don't relish the idea of frantically skimming it. If anybody has the exact quote with source info, that'd be great. Thanks!
