It is funny this conversation has been in my head since my last comment and I have been raising this point with a few people.
Definition of Art is definitely an unresolved question and in many ways I love the fact that it is. I do believe it is one of the mysteries of life that allows creativity: because art is still undefined, subjective standards about what we consider as Art gets higher, so whatever we will want to create to our subjective satisfaction will have to be of the highest quality we can give.
Trying to find a representation of Art through our creativity is probably a way for artists to never be satisfied with mediocrity.
I'm really glad to know that our conversation got stuck in your head. Most of the topics I write about are something that I've been thinking about for a long time.
Interesting thoughts. Probably many people do tend to strive to achieve greatness more when there are no clear standards - no standards, no limits.
Cheers! : )
