Great art is always informed by intelligence, but it is not about ideas. Never has been. Never will be.
Picasso's art was never about ideas. Although the early cubist work was informed by his thoughts about what it would be like to have multiple views of something seen simultaneously, it was not about the idea of that. It was about the sensation of that--a very different thing.
Thnking and feeling are not mutually exclusive, but they sure are different. It is quite a different thing to feel something and to think you feel it.
