“How is that?” Kelly said.
“Human beings are so destructive,” Malcolm said. “I sometimes think we’re a kind of plague, that will scrub the earth clean. We destroy things so well that I sometimes think, maybe that’s our function. Maybe every few eons, some animal comes along that kills off the rest of the world, clears the decks, and lets evolution proceed to its next phase.”
Kelly shook her head. She turned away from Malcolm and moved lip the boat, to sit alongside Thorne.
“Are you listening to all that?” Thorne said. “I wouldn’t take any of it too seriously. It’s jist theories. Human beings can’t help making them, but the fact is that theories are just fantasies. And they change. When America was a new country, people believed in something called phlogiston. You know what that is? No? Well, it doesn’t matter, because it wasn’t real anyway. They also believed that four humors controlled behavior. And they believed that the earth was only a few thousand years old. Now we believe the earth is four billion years old, and we believe in photons and electrons, and we think human behavior is controlled by things like ego and self-esteem. We think those beliefs are more scientific and better.”
“Aren’t they?
Thorne shrugged. “They’re still just fantasies. They’re not real. Have you ever seen a self-esteem? Can you bring me one on a plate? How about a photon? Can you bring me one of those?”
Kelly shook her head. “No, but…”
“And you never will, because those things don’t exist. No matter how seriously people take them,” Thorne said. “A hundred years from now, people will look back at us and laugh. They’ll say, ‘You know what people used to believe? They believed in photons and electrons. Can you imagine anything so silly?’ They’ll have a good laugh, because by then there will be newer and better fantasies.” Thorne shook his head. “And meanwhile, you feel the way the boat moves? That’s the sea. That’s real. You smell the salt in the air? You feel the sunlight on your skin? That’s all real. You see all of us together? That’s real. Life is wonderful. It’s a gift to be alive, to see the sun and breathe the air. And there isn’t really anything else. Now look at that compass, and tell me where south is. I want to go to Puerto Cortés. It’s time for us all to go home.”
Acknowledgments
This novel is entirely fiction, but in writing it, I have drawn on the work of researchers in many different fields. I am especially indebted to the Work, and the speculations, of John Alexander, Mark Boguski, Edwin Colbert, John Conway, Philip Currie, Peter Dodson, Niles Eldredge, Stephen Jay Gould, Donald Griffin, John Holland, John Horner, Fred Hoyle, Stuart Kauffman, Christopher Langton, Ernst Mayr, Mary Midgley, John Ostrom, Norman Packard, David Raup, Jeffrey Schank, Manfred Schroeder, George Gaylord Simpson, Bruce Weber, John Wheeler, and David Weishampel.
It remains only to say that the views expressed in this novel are mine, not theirs, and to remind the reader that a century and a half after Darwin, nearly all positions on evolution remain strongly contended, and fiercely debated.
