"Noble though the wartime aspirations of the liberal Establishment might be, New Jerusalem nevertheless constituted – just like the postwar illusion of Britain as a present and future world and Commonwealth power, or the pre-war faith in the League of Nations as a preserver of world law and order – a piece of romantic fantasising, rather like some gigantic palace in an engraving by Piranesi. And just as Piranse's imagination defied the laws of physics and geometry, so did the dreamers of New Jerusalem disregard the real-life problem of funding its construction out of what was now a bankrupt and backward industrial economy instead of the richest in the world that it had been in their youth."
