I went to the Cy Twombly exhibition at the Tate Modern. It was good. I didn’t feel particularly engaged by it though. I’ve never been a stare-at-one-painting-for-an-hour kind of guy, but I was in and out in about thirty minutes. I spent more time in the shop, looking at the same images, but in purchasable form. Am I a philistine? Numbed by 21st century mass media? What’s my problem?
