I'd be happy if anyone quoted me as a source for an idea, but I don't think I've said anything original. At most, I've pointed out another metaphor. But the balance between the critic and the actual art in explaining something is more complicated that it seems. For older works, or those from unfamiliar cultures, we don't have the context the artist is working in. How many people today know about the town of Guernica? What does not knowing do to the painting. And a good critic will add context. There are things which I write that have overloads of meaning that I'm not immediately conscious of. When I was fiddling with a fox=headed humanoid Poser character, and put it in an SS uniform, I was echoing a picture of Heydrich which I'd once seen. I wasn't actually conscious as I worked that his forename happens to be one of the literary names for the fox. The jokes about the final solution to the chicken problem came later. Sometimes my mind scares me.
