God lies within - what does this mean? Shared between artist and audience is that doubling up of the world that occurs in the work. This might sound mysterious. We can think of it with Heidegger: there is a difference, he says, between being, understood as the horizon against which things come to appear, and beings, those particular things, people, which appear to us. Anything is more than it appears to be. Or rather, this 'to be' watches over the indeterminability of the experience of the world and gives itself to be experienced as the engagement in question.
