The defence against chance

He had always disliked the people who encored a favourite air in the opera—'That just spoils it' had been his comment. But this now appeared to him as a principle of far wider application and deeper moment. This itch to have things over again, as if life were a film that could be unrolled twice or even made to work backwards … was it possibly the root of all evil? No: of course the love of money was called that. But money itself—perhaps one valued it chiefly as a defence against chance, a security for being able to have things over again, a means of arresting the unrolling of the film.
