Opinion Essay: „One language spoken worldwide would lead to better international relations.” As the director Frederico Fellini once said, „A different language is a different vision of life”. Taking into account that linguists estimate the number of languages spoken by people all over the world at around 6-7 thousands, it is very difficult to imagine all people speaking only one language. In my opinion, it is impossible to prevent internal conflicts and improve international relations by using worldwide one language. In the first place, I think that one language is not a basis for peaceful relations. Even homogeneous societies struggle with internal conflicts, have problems with communication and cooperation. It seems to me that our mentality, traditions, history are more important factors both for local and international relations. It is also possible to find examples of countries, where there was a division and demarcation of new borders, like in Sudan, even though their inhabitants speak the same language. Moreover, communicating by one language would lead to a lack of local cultures and the disappearance of the concept of 'international' and 'internal' relations. I definitely feel that our strength lies in the distinctiveness and diversity, without which our life would be boring and humdrum. Therefore our languages should be consider as the significant part of our cultures for which we should give special protection. Furthermore, I am not convinced that it is possible to create or choose one universal language. Our language code illustrates our way of thinking and understanding reality, so in my view it is impossible to impose on people's perception of the world. History knows a lot of examples of indoctrination, but in most cases these attempts to deepen the sense of national identity. On the other hand, there are also those who are convinced that one language could provide some conveniences. It is often believed that it would be easier to work and study abroad, and international cooperation would function more effectively. Besides that, the lack of language barrier could be very useful in international politics and cooperation between countries from all over the world. Taking all this into consideration, I think that there is very little chance that one language spoken worldwide would lead to better international relations. It cannot be denied that, as said Antointe de Saint-Exupery, „Language is the source of misunderstunding”, but these misunderstandings and conflicts can occur both in linguistically diverse and homogeneous areas.
