Why is there art?

I saw this quote the other day and I truly believe in it it state "If a composer could say what he had to say in words he wouldn't bother trying to say it in music"-Gustav Mahler 

I believe this quote goes for all art. If any artist could really show or say what they need to say or do, why would they make art. As an artist I believe it is truly impossible to tell the story you need to with out art and creativity.

Let's say your parents got divorced and you felt as if you were being tugged in several different directions. If you were to just tell someone "I feel lie I am being tugged in several different directions." it would not have the same effect and be as deep and real as if you were to paint a picture of you being garbed and pulled by many different arms ripping away peace after peace of your body taking you away leaving you empty.

This is why art exist to tell a story unable to be told in words.
