Rosalind Krauss’s essay, Sculpture in the Expanded Field, is not only a corner stone of critical theory, it is a very important touchpoint for me personally. (I explained my attachment in a recent post about her Klein group diagram & Star Wars.) Written over thirty years ago (Krauss's essay, not my post), it remains one of the best pieces of writing about contemporary sculpture - but like the great majority of top tier art writing it can make for dense and difficult reading. I have spent the last year and a half or so combing through the essay and it was only recently, as I prepared my post for HyperAllergic that I dug up what I think is the most important element of Krauss's argument.
