"that's how things are. A day is like a whole life. You start out doing one thing, but end up doing something else, plan to run an errand, but never get there.... And at the end of your life, your whole existence has that same haphazard quality, too. Your whole life has the same shape as a single day." "I guess it's one way to look at things," Grant said. "No," Malcolm said. "It's the only way to look at things. At least, the only way that is true to reality. You see, the fractal idea of sameness carries within it an aspect of recursion, a kind of doubling back on itself, which means that events are unpredictable. That they can change suddenly, and without warning." "Okay ..." "But we have soothed ourselves into imagining sudden change as something that happens outside the normal order of things. An accident, like a car crash. Or beyond our control, like a fatal illness. We do not conceive of sudden, radical, irrational change as built into the very fabric of existence. Yet it is. And chaos theory teaches us," Malcolm said, "that straight linearity, which we have come to take for granted in everything from physics to fiction, simply does not exist. Linearity is an artificial way of viewing the world. Real life isn't a series of interconnected events occurring one after another like beads strung on a necklace. Life is actually a series of encounters in which one event may change those that follow in a wholly unpredictable, even devastating way." Malcolm sat back in his seat, looking toward the other Land Cruiser, a few yards ahead. "That's a deep truth about the structure of our universe. But, for some reason, we insist on behaving as if it were not true."
