"Well, the Germans, too, are surrounded by a “great wall.” This wall is not built of masonry, but is spiritual. Anything outside the wall is regarded with contempt. But when such a superior person goes abroad, and finds how much he has been misinformed, he is apt, unless he is a person of very stable temperament, to rush to the opposite extreme, and thence to look down upon all that he has previously venerated. That is why so many Germans who go abroad are lost to Germany. But one who, having gone abroad, remains a good German and wants to enlighten his fellow-countrymen is not understood at home and is despitefully used."
