It is said that language poses a problem in the study of philosophy because, for example in the English language, of the different meanings a single word can have and because there are no words to describe certain concepts, mixed thoughts, mixed emotions, etc. However, some languages are supposed to be better than others (for the purpose of understanding / teaching philosophy) Sanskrit apparently being the best / one of the best. Is this true and is it worthwhile learning Sanskrit for the purpose of greater understanding of philosophy?
Suppose that you have a conceptual problem about e.g. your notion of moral responsibility (or justice, or freedom, or causation, or whatever). How could doing your philosophical thinking in Sanskrit terms possibly help? Either the concepts available in Sanskrit are the same as yours -- in which case, they will raise the same problems, and the move gains you nothing. Or they are different concepts -- in which case, thinking about them won't resolve the problems you started off with, which were problems to do with your concepts, and again the move gains you nothing (except additional problems).
