Speaking broadly and ignoring many exceptions, one may say that Americans come to Europe chiefly to find satisfaction for those parts of human nature which are least catered to in their own country. A degenerate Italian aristocrat with a name familiar in Renaissance history is more interesting to these Americans than Einstein. To Europeans, unless they are professional antiquaries, such an attitude is impossible, since they have to live in the present and, if possible, make Europe fit to live in.

米国人も他の言語を習得したらよいではないか？ 米国においても、どの外国語でもよいので外国語を１つ義務教育で習わせるとよい。そうすればもっと他国に対する理解が進むであろう。
