Einstein's Dreams - Alan Lightman [14]
A world without memory is a world of the present. The past exists only in books, in documents. In order to know himself, each person carries his own Book of Life, which is filled with the history of his life. By reading its pages daily, he can relearn the identity of his parents, whether he was born high or born low, whether he did well or did poorly in school, whether he has accomplished anything in his life. Without his Book of Life, a person is a snapshot, a two-dimensional image, a ghost. In the leafy cafés on the Brunngasshalde, one hears anguished shrieking from a man who just read that he once killed another man, sighs from a woman who just discovered she was courted by a prince, sudden boasting from a woman who has learned that she received top honors from her university ten years prior. Some pass the twilight hours at their tables reading from their Books of Life; others frantically fill its extra pages with the day’s events.
With time, each person’s Book of Life thickens until it cannot be read in its entirety. Then comes a choice. Elderly men and women may read the early pages, to know themselves as youths; or they may read the end, to know themselves in later years.
Some have stopped reading altogether. They have abandoned the past. They have decided that it matters not if yesterday they were rich or poor, educated or ignorant, proud or humble, in love or empty-hearted—no more than it matters how a soft wind gets into their hair. Such people look you directly in the eye and grip your hand firmly. Such people walk with the limber stride of their youth. Such people have learned how to live in a world without memory.

Dawn. A salmon fog floats through the city, carried on the breath of the river. The sun waits beyond the Nydegg Bridge, throws its long, reddened spikes along Kramgasse to the giant clock that measures time, illuminates the underside of balconies. Sounds of morning drift through the streets like the smell of bread. A child wakes and cries for her mother. An awning creaks quietly as the milliner arrives at his shop on Marktgasse. An engine whines on the river. Two women talk softly beneath an arcade.
As the city melts through fog and the night, one sees a strange sight. Here an old bridge is half-finished. There, a house has been removed from its foundations. Here, a street veers east for no obvious reason. There, a bank sits in the middle of the grocery market. The lower stained-glass windows of St. Vincent’s portray religious themes, the uppers switch abruptly to a picture of the Alps in spring. A man walks briskly toward the Bundeshaus, stops suddenly, puts his hands to his head, shouts excitedly, turns, and hurries in the opposite direction.
This is a world of changed plans, of sudden opportunities, of unexpected visions. For in this world, time flows not evenly but fitfully and, as consequence, people receive fitful glimpses of the future.
When a mother receives a sudden vision
