Louise Nevelson

"Well, I think that the shadow, let's say, for a better word, is the fourth dimension. That shadow I make forms out of is just not a fleeting shadow but it has as much form as a Cubistic form would have. It has forms and I give them forms and to me they're much more exciting than anything that I see on earth. That is another reason that I don't particularly need to travel because I'm always fascinated by these forms; they mean something. I call it, for clarification, the fourth dimension. I don't need so much material and matter to tune in and identify and recognize that fourth dimension. To me that's remarkable and very wonderful, very wonderful. And probably night and day are very necessary for my kind of thinking, the light and the dark: very important."
