According to ESL teachers, it takes seven years for an adult to learn a new language well enough that native speakers will want to talk to you. Although a child can probably acquire a language in less time than that, it is also true that the child will lose the language if he or she stops using it before adulthood. I have seen many arguments for the value of learning a second language, but they all strike me as flimsy. Please tell me why a student who already knows English or even Spanish or Mandarin should invest thousands of hours learning a second language when there are more than enough sciences and practical arts with much clearer educational value to last anyone a lifetime of learning.

Well, if you don't place much weight on foreign language, that's okay -- my point still stands. U.S. performance in math and science is comparatively disappointing.

I can't really agree with your position on language learning, but I'm a little biased. I've studied Ancient Greek, German, Chinese and Middle English.

Well, it is easy. Mandarin is a quite useful language if you are living in China, but it wouldn't help you if you are in Iceland.

Also, I've heard (don't remember where...) that not all languages are equal when conveying an idea: for example eskimos have a lot of words for snow and white. Some concepts would be very hard to express in any other language.

My point of view is clearly viased: I speak Catalan and Spanish (mother tongues) and I'm more or less fluent in English (hoping to take the CPE this june).
