Painting is the making of an analogy for something non-visual and incomprehensible - giving it form and bringing it within reach. And that is why good paintings are incomprehensible. Creating the incomprehensible has absolutely nothing to do with turning out any old bunkum, because bunkum is always comprehensible.
