“There is not much talk about the clouds that are visible up here. No one seems to think it remarkable that somewhere above an ocean we are flying past a vast white candy-floss island that would have made a perfect seat for an angel or even God himself in a painting by Piero della Francesca. In the cabin, no one stands up to announce with requisite emphasis that if we look out the window, we will see that we are flying over a cloud, a matter that would have detained Leonardo and Poussin, Claude and Constable.”

“Perhaps the easiest people to fall in love with are those about whom we know nothing. Romances are never as pure as those we imagine during long train journeys, as we secretly contemplate a beautiful person who is gazing out of the window – a perfect love story interrupted only when the beloved looks back into the carriage and starts up a dull conversation about the excessive price of the on-board sandwiches with a neighbour or blows her nose aggressively into a handkerchief.”

“We are sensitized by the books we read. And the more books we read, and the deeper their lessons sink into us, the more pairs of glasses we have. And those glasses enable us to see things we would have otherwise missed.”

“We wanted to test each other's capacity for survival: only if we had tried in vain to destroy one another would we know we were safe.”

“We need a home in the psychological sense as much as we need one in the physical: to compensate for a vulnerability. We need a refuge to shore up our states of mind, because so much of the world is opposed to our allegiances. We need our rooms to align us to desirable versions of ourselves and to keep alive the important, evanescent sides of us.”

“At the beginning of human history, as we struggled to light fires and to chisel fallen trees into rudimentary canoes, who could have predicted that long after we had managed to send men to the moon and areoplanes to Australasia, we would still have such trouble knowing how to tolerate ourselves, forgive our loved ones, and apologise for our tantrums?”

“How quickly all the advantages of technological civilisation are wiped out by a domestic squabble. At the beginning of human history, as we struggled to light fires and to chisel fallen trees into rudimentary canoes, who could have predicted that long after we had managed to send men to the moon and aeroplanes to Australasia, we would still have trouble knowing how to tolerate ourselves, forgive our loved ones and apologise for our tantrums?”
