It is a question I have been thinking about a lot: How does language influence how people in different countries think? Do people change when they switch to another language? How closely is language connected to culture and mentality?
The Wall Street Journal
has published a very interesting article on this topic, proving that languages and the way we think are depending on each other, even though it is not clear if languages influence behaviour or if our behaviour influenced the creation of the different languages.
In my 4 1/2 years in Sweden I have made the experience that the Swedish language is pretty limited in the amount of words available, compared to the very complex and versatile German language. The consequence is that Swedes have much less possibilities to differentiate themselves by using language, unlike Germans who pretty much can make everybody understand to which part of the society (or class) they belong by only saying two sentences (note that I don't claim that the Swedish language does not allow for differentiation at all). And having a look at the two countries, Sweden is much less divided into classes and social groups than Germany. Could language (among other factors) be responsible for that?
I also find that Swedes have the great skill of simplifying complicated context by removing all the unnecessary information and keeping its core. My perception is that Germans generally don't have this skill. Now I'm asking myself if the (or one) reason could be the limitations of the Swedish language, which simply does not seduce people to say more than necessary? From my own experience I can tell that this is not the case with German: You can vary the German language in a way that allows for talking for 10 minutes without actually saying anything.
Maybe all this is too far-fetched. But it is worth to think about and to do some more research on.
Let's for one second assume that in culture and behaviour are strongly connected to the language spoken in a country - the conclusion would be that some countries could have serious disadvantages in adapting to specific situations as long as they keep their language... Germans would always remain complicated and the German society would always be fragmented, in the same way the language is.
