" The highway looked different to him now, as they drove on. In theory it was the same stretch of tarmac, bounded by the same traffic paraphernalia and flimsy metal fences, but it had been transformed by their own intent. It was no longer a straight line to an airport, it was a mysterious hinterland of shadowy detours and hidey-holes. Proof, once again, that reality was not objective, but always waiting to be reshaped and redefined by one’s attitude. Of course, everybody on earth had the power to reshape reality. It was one of the things Peter and Beatrice talked about a lot. The challenge of getting people to grasp that life was only as grim and confining as you perceived it to be. The challenge of getting people to see that the immutable facts of existence were not so immutable after all. The challenge of finding a simpler word for immutable than immutable. "
