"The one object of fifty years of abstract art' wrote Ad Reinhardt, 'is to present art-as-art and as nothing else, to make it into the one thing it is only, separating and defining it more and more, making it purer and emptier" (Reinhardt quoted in Jonathan Fineberg, Art Since 1945, Strategies of Being, London, 2000, p. 297).
