"The Universe is very, very big. It also loves a paradox. For example, it has some extremely strict rules. Rule number one: Nothing lasts forever. Not you or your family or your house or your planet or the sun. It is an absolute rule. Therefore when someone says that their love will never die, it means that their love is not real, for everything that is real dies. Rule number two: Everything lasts forever."

A world in which time is absolute is a world of consolation. For while the movements of people are unpredictable, the movement of time is predictable. While people can be doubted, time cannot be doubted. While people brood, time skips ahead without looking back. In the coffee houses, in the government buildings, in boats of Lake Geneva, people look at their watches and take refuge in time. Each person knows that somewhere is recorded the moment she was born, the moment she took her first step, the moment of her first passion, the moment she said goodbye to her parents.
