" The arts are obsessional, and obsession is dangerous. It's like a knife in the mind. In some cases—Dylan Thomas comes to mind, and Ross Lockridge and Hart Crane and Sylvia Plath—the knife can turn savagely upon the person wielding it. Art is a localized illness, usually benign—creative people tend to live a long time—sometimes terribly malignant. You use the knife carefully, because you know it doesn't care who it cuts. And if you are wise you sift the sludge carefully . . . because some of that stuff may not be dead. "
