Language: a determinant?

In class we briefly discussed language as a determinant in the nature verses nurture topic. I believe that many languages are all encompassing and directly relate back to the culture. It is evident that all languages are based upon different symbols and that some ideas and sayings do not translate from language to language. Language also determines who we communicate with, and thus if we are not familiar with different languages we will not communicate with those people. By not being able to communicate with different people we might be missing out on certain ideas and thoughts. Perhaps we are not aware of different thoughts of ideas until we see or hear of them. Therefore, by not communicating with other languages we can inhibit our ability to flourish and thus language can be considered a direct determinant of our human nature.
