I found couple ideas from chapter 5 interesting for me. The first one is idea of Ethnocentrism (p.341).

 It is so funny to observe how people from different cultures think they are superior to all others. I remember how during the Soviet Union people in Russia had been taught that to think that they are the smartest nation in the world. The worst thing was that people were not allowed to go abroad. Everyone who would dare to doubt correctness of socialism could end up so far from civilization. I used to think that ethnocentrism among Slavik nations was caused by political ideology. Even now, after more then 20 years as the Soviet Union has been eliminated, people still try to prove that they are better then other. It is so funny to read Russian news when they tell stories about USA and what's going on here. The same event can be presented in completely opposite ways. At the same time, ethnocentrism is of the key element in any ideology or idea of nation. By allowing people to consider themselves superior we get patriots, desire for improvement and so on. Competition helps us do not stay at the same place, but move forward. 

The second idea that caught my attention was idea of Personal Predisposition (344). Everyone who moved to a new culture knows how big is temptation to go back, especially when everything goes not well at the moment. All the time talks about going back circulate among immigrants from Russia or Ukraine. In most case older people live every day with dream to go back. People, who have lived in the US for more than 10 years still dreaming to go back home, but just few of them recognize that it is impossible to turn back. Within years everything is changing, there is no more homeland, one as it used to be 10 years ago. Everyone, who migrated to America is considered as American by those who stayed in homeland. Some people tried to go back, but they were very disappointed, because they had returned to a different country with a new culture. I think that every place is good enough to live at, as long as we predispose ourselves to think so.
