I understand Keynes completely now
At least his comment about how he could only understand material in written German that he to some extent already understood well. My Italian is about at that point now. When I read an Italian newspaper, I can understand a story about Obama's trip to Israel pretty well, since I know the topic already. But the articles on Italian politics I really don't get at all. I think this is just the sort of thing of which Keynes was speaking.
