It is a cold morning in November and the first snow has fallen. A man in a long leather coat stands on his fourth-floor balcony on Kramgasse overlooking he Zahringer Fountain and the white street below. To the east, he can see the fragile steeple of St. Vincent's Cathedral, to the west, the curved rook of the Zytgloggeturm. but the man is not looking east or west. He is staring down at a tiny red hat left in the snow below, and he is thinking. Should he go to the woman's house in Fribourg? His hands grip the metal balustrade, let go, grip again. Should he visit her? Should he visit her?
He decides not to see her again. She is manipulative and judgemental, and she could make his life miserable. Perhaps she would not be interested in him anyway. So he decides not to see her again. Instead, he keeps to the company of men. He works hard at the pharmaceutical, where he hardly notices the female assistant manager. He goes to the brasserie on Kochergasse in the evenings with his friends and drinks beer, he learns to make fondue. Then, in three years, he meets another woman in a clothing shop in Neuchatel. She is nice. She makes love to him very very slowly, over a period of months. After a year, she come to live with him in Berne. The live quietly, take walks together along the Aare, are companions to eachother, grow old and contented.
In the second world, the man in the long leather coat decides that he must see the Fribourg woman again. He hardly knows her, she could be manipulative, and her movements hint at volatility, but that way her face softens when she smiles, that laugh, that clever use of words. Yes, he must see her again. He goes to her house in Fribourg, sits on the couch with her, within moments feels his heart pounding, grows weak at the sight of the white of her arms. They make love, loudly and with passion. She persuades him to move to Fribourg. He leaves his job in Berne and begins work at the Fribourg Post Bureau. He burns with his love for her. Every day he comes home at noon. They eat, they make love, they argue, she complains that she needs more money, he pleads with her, she throws pots at him, they make love again, he returns to the Post Bureau. She threatens to leave him, but she does not leave him. He lives for her, and he is happy with his anguish.
In the third world, he also decides that he must see her again. He hardly knows her, she could be manipulative, and her movements hint at volatility, but that smile, that laugh, that clever use of words. Yes, he must see her again. He goes to her house in Fribourg, meets her at the door, has tea with her at her kitchen table. They talk of her work at the library, his job at the pharmaceutical. After an hour, she says that she must leave to help a friend, she says goodbye to him, they shake hands. He travels the thirty kilometers back to Berne, feels empty during the train ride home, goes to his fourth-floor apartment on Kramgasse, stands on the balcony and stares down at the tiny red hat left in the snow.
These three chains of events all indeed happen, simultaneously. For in this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, whether to visit a woman in Fribourg or to buy a new coat, the world splits into three worlds, each with the same people but with different fates for those people. In time, there are an infinty of worlds.
Some make light of decisions, arguing that all possible decisions will occur. In such world, how could one be responsible for his actions? Others hold that each decision must be considered and committed to, that without commitment there is chaos. Such people are content to live in contradictory worlds, so long as they know the reason for each.
