Beauty and the best

Another enjoyable Dalrymple jeremiad on art. Here's an excerpt:

Let me take the second point first. One often hears of 'cutting-edge' art; indeed, the much older term, avant garde, is of the same ilk. This suggests that there is progress in the arts, as there is in science, and that what comes after must, in some sense, be better than what came before. Art has some kind of destination, with later artists further along the road to it than earlier.

In science, progress is a fact (except for the most extreme of epistemological sceptics, none of whom, nevertheless, would be entirely indifferent as to whether their surgeon used the surgical techniques of, say, the 1830s, rather than those of this century). The most mediocre bacteriologist alive today knows incomparably more that did Louis Pasteur or Robert Koch, for example; the most mediocre physics graduate knows incomparably more than Sir Isaac Newton ever did. This is because scientific knowledge is cumulative. But no one would suggest that the paintings of Rothko were better than those, say, of Chardin because he lived a long time after Chardin, and that Chardin's were better than those of Velasquez for the same reason.
