To illustrate this, Brady cites the emotional experience of staring at the night sky: "In casting our eyes across it we cannot take it all in," she writes. "We can look to the left and the right, and all around, but it seems to go on forever, filling space and extending outwards in all directions in such a way that we cannot put any boundaries around it through perception. Through this kind of aesthetic experience we have a kind of sensuous feeling for the infinite, one which is quite different from any kind of intellectual, mathematical idea of it."
