In his marriage, he now realized, the principle of progress was always at work, in the acquiring of houses, possessions, cars, the drive towards higher social status, more travel, a wider circle of friends, even the production of children felt like an obligatory calling-point on the mad journey; and it was inevitable, he now saw, that once there were no more things to add or improve on, no more goals to achieve or stages to pass through, the journey would seem to have run its course, and he and his wife would be beset by a great sense of futility and by the feeling of some malady, which was really only the feeling of stillness after a life of too much motion, such as sailors experience when they walk on dry land after too long at sea, but which to both of them signified that they were no longer in love. If only we had had the sense, he said, to make our peace with one another then, to start from the honest proposition that we were two people not in love who nonetheless meant one another no harm; well, he said, his eyes brimming again, if that had been the case I believe we might have learned truly to love one another and to love ourselves. But instead we saw it as another opportunity for progress, saw the journey unfolding once more, only this time it was a journey through destruction and war, for which both of us demonstrated just as much energy and aptitude as always.
