Would this be considered at all, or is this not even important? I am not talking about fields which have these foreign languages as their object of study, or where it is obvious that the language would help (if I were to study French Literature, knowledge of French would obviously be important).
But what about fields which are primarily English, so say I want to do my PhD in Political Theory. There are probably a few articles in foreign languages I could make use of, but English seems just fine. Would knowing a foreign language still be an advantage, or not really?
