'Is there art which does not spark emotion?' Sure there is, many great minds have tried to define at a concrete level what "Art" is or is not, every-time someone does then there are works that break that definition. Here something else to break. To me "Art" is the result of an artist sharing their "Vision", good art is well executed and facilitates that sharing. If your vision is VITWAS and that's what you achieve, excellent art. If your vision is, like the early cubists something new or defines itself by testing bounds and you achieve that vision then excellent art. If your vision is abstract and inaccessible, and you maintain that in your work, then you have achieved art. If your vision is emotional, rational or technical and you capture those qualities in the work then you have artistic success. Far to much thinking. Going back to banging rocks together now.
