Each of them wanted more than anything to be declared right, and the other wrong, but it was impossible to assign blame entirely to either of them. And I realised eventually, I said, that it could never be resolved, not so long as the aim was to establish the truth, for there was no single truth any more, that was the point. There was no longer a shared vision, a shared reality even. Each of them saw things now solely from his own perspective: there was only point of view.
