And I do think that good art - the art that tends to last - is that art that hits human beings on several different levels at once because everybody's different. Some people approach art through their emotions, others through their head, and the art that can appeal to all of those levels is more likely to reach more people. Having more people see the work doesn't necessarily mean better art but it stands a better chance of lasting.
There is a good deal of art that in some traditions of conceptual work are anti-affect, in fact a very large chunk of mainstream art after 1950 took against affect art altogether because they said, "No, we hate affect art because this is how we get manipulated by totalitarianism and therefore artists shouldn't play that game." And a lot of artists agreed to play that game, which I personally believe is to the loss of art.
Having more curators to go around among the artists is more effective and more efficient. The artists are better looked after so you get better works. What isn't so effective is actually that some visitors and some members of the press really want a single voice with which they can relate.
There are so many people who have a training in art history; and if you've spent time looking at old art, you become attuned to what art does through materiality and so you begin to look to that in contemporary art as well. And anyway, I do think that matching one's experience with what you're looking at and questioning what you're looking inevitably involves materiality, just like it involves the sense of place.
