Genius is "God given". It is rare. I'm not aware of any more than a handful of names from the past.Do you believe in a God that blesses some composers with massive amounts of talent, or is it all in nature/nurture?
I personally don't follow faith based thinking, but leave it open to the possibility of a god. So, my answer to my own question is, perhaps, but I'm not going to live my life believing so without scientific evidence.
