I believe that the artist's feelings are in some way generative. And I suspect that much of the artist's most productive emotion - not all of it but much of it - is felt in the course of playing around with form.
We all sort of do want incentives for creative people to still exist at a certain level. You know, maybe rock stars shouldn't make as much; who knows? But you want as much creativity to take place in the future as took place in the past.
