No doubt about it now: both music tapes are twelve days long. They are repeating themselves, and if we feel inclined we can start to make exact schedules of what we shall be hearing in twelve days, a fortnight, a month, or ten years. All we have to do is to mark each day on a calendar what tune is played at what hour, and then mark the same tune at the same time twelve days ahead and twenty-four days ahead and thirty-six days and so on as long as the calendar lasts. What a horrible idea.
Nobody has started to make schedules yet, as far as I know. But people have been talking about the tapes a great deal for the last twenty-four hours. Even X-107 has been a bit depressed by this business. He does not say so, but I can sense it. He seems to have lost his enthusiasm for the music, and if I switch on the tape he asks me if I would mind turning it off. The music must have meant more to him than to me.
Even so, I cannot get him to admit that he resents the limited supply of music. To him Level 7 is still the best of all possible worlds. When I suggested that they could at least have arranged for a tape that would run for a man’s lifetime, so that he might never know when it came to an end and started again, X-107 retorted that this was absurd.
“Level 7,” he said, “is limited, very limited, in space. You can see that for yourself. There’s no room for luxuries. Think of the difficulty of providing the basic necessities for five hundred people to live down here for half a millennium: enough food, supplies and energy to make us a completely self-sufficient community over four thousand feet underground—when until recently sub-continents found it hard enough to be self-sufficient on the surface of the globe. To achieve all this is nothing less than a miracle of human ingenuity and scientific progress.”
“You make me feel grateful,” I remarked sarcastically, “that we have recorded music at all.”
“And so you should,” replied X-107. “They made room down here for a lounge. You don’t expect a concert hall as well, do you?”
“All right, but what about books?” I said. “Sometimes I wish I had something to read besides my own diary. I suppose you’ll say I should be grateful for the paper I write on.”
“Would you rather starve in a library?”
At that I gave up the argument. It was clear that X-107 would never be convinced by my point of view, because he would never allow himself to be convinced: it was necessary for him to believe in the inevitability of the arrangements on Level 7, because only in that way could he console himself for their disadvantages.
So because there is limited space on Level 7 there is no room for a very long music-tape; and if there is no room for a long tape there is no room for the idea of infinity. Better forget it.
