The way people communicate I guess there's no way to take a deep look inside tradition, mentality, the very way of life of a country but learning language spoken in it. For instance, Russian literacy is essential for proper understanding and appreciation of Tarkovsky's best films, Pushkin's high form of poetry. Possibly the reason why Pushkin was never recognized as a great poet outside Russia is that his poetry is deeply connected to his native language. He spoke fluent French but his verses he kept deliberately russian. Even simple comunication between people of different cultures is affected by differing experiences of the nations they represent. The idioms differ drastically from one language to another so do even prepositions. Can people find or invent a single common language for all, or should they? Not in my opinion. I guess they just should try to learn each other's language, try to give up thinking of their point of view as of something universally true. Besides, in all languages paying respect to your partner is the only way to keep really good conversation. What is learning foreign language if not paying respect to many people (your friends) that are ready to communicate with you?
