Human thought

I see the inner musing of man as a form of art.  Man's ideas, theories, and thoughts are true artwork.  Some art may be more sophisticated than others or may be considered better.  Some art is more abstract and some is more conformed.  Regardless of what kinds of art it is, the artist still has some reason to hesitate before sharing his art with the world.  What if it goes unappreciated?  What if the world doesn't understand it's true meaning?  What if I lose standing in society for sharing it?  Is my art too abstract?  Is my art strong enough to hold it's own?  Those are all questions the artist faces before sharing his art, and some of those answers may cause him to hold his idea in to share it with a more understanding crowd who will appreciate it for what it is and not question the piece or the artist.
