Fluke – von Brian Klaas

Ein bisschen zu lang. Aber es verändert die Perspektive auf die Welt dramatisch. Alles ist deutlich mehr von Zufällen bestimmt, als wir mit unserer alles erklärenden Maschine im Schädel wahr haben wollen.

Meine Notizen

• After weighing up the alternatives, they agreed on a target. The first bomb would be dropped on Kyoto. But why was Kyoto spared? And why was Nagasaki — a city that hadn't even been considered a top-tier bombing target — destroyed? Remarkably, the lives of roughly two hundred thousand people teetered between life and death because of a tourist couple and a cloud.
• If hundreds of thousands of people could live or die based on one couple's vacation choice decades earlier, which seemingly trivial choices or accidents could end up drastically changing the course of your life, even far into the future?
• When given the choice between complex uncertainty and comforting — but wrong — certainty, we too often choose comfort.
• You may not know the names of all eight of your great-grandparents off the top of your head, but when you look in the mirror, you are looking at generational composites of their eyes, their noses, their lips, an altered but recognizable etching from a forgotten past.
• When we meet someone new, we can be certain of one fact: none of their direct ancestors died before having children.
• Your life depends on the courting of countless people in the Middle Ages, the survival of your distant Ice Age ancestors against the stalking whims of a saber-toothed tiger, and, if you go back even further, the mating preferences of chimpanzees more than 6 million years ago. We are the surviving barbs of a chain-link past, and if that past had been even marginally different, we would not be here.
• Amor fati means accepting that truth, even embracing it, recognizing that we are the offshoots of a sometimes wonderful, sometimes deeply flawed past, and that the triumphs and the tragedies of the lives that came before us are the reason we're here. We owe our existences to kindness and cruelty, good and evil, love and hate.
• "We are going to die, and that makes us the lucky ones," Richard Dawkins once observed. "Most people are never going to die because they are never going to be born."
• Is the world contingent or convergent? The central question is whether evolution proceeds in predictable ways, regardless of freak events and random fluctuations, or if those contingencies can lead evolution down diverging paths.
• Convergence is the "everything happens for a reason" school of evolutionary biology. Contingency is the "stuff happens" theory.
• That led Lorenz to a realization that cracked the foundations of how we understand the world. Even in a clockwork universe with controlled conditions, minuscule changes can make an enormous difference. Lorenz's findings created the concept of the butterfly effect, the notion that a butterfly flapping its wings in Brazil could trigger a tornado in Texas.
• Because small changes can make such a big difference, the universe will always appear uncertain, even random, to us.
• Confidence in a predictable future, therefore, is the providence of charlatans and fools. Or, as the theologian Pema Chödrön put it, "If you're invested in security and certainty, you are on the wrong planet."
• Heraclitus, the ancient Greek philosopher, rightly pointed out, "No man ever steps in the same river twice. For it's not the same river and he's not the same man." To that, Cratylus, a student of Heraclitus, added that we are not mere passive observers. When you step in a river, you change it.
• It's time to adjust our lenses of how we see ourselves within the world. Our chaotic, intertwined existence reveals a potent, astonishing fact: We control nothing, but influence everything.
• Despite thousands of years of innovations and breathtaking scientific advances, you'd be more likely to survive if you were marooned on a tropical island with a tradesman or farmer from ancient Rome or medieval England than with most modern professionals.
• "There are more bacteria in your gut than stars in our galaxy."
• Understanding the relational, intertwined nature of reality changes — for the better — how we experience the world.
• It's unsettling that the entirety of the human saga can be traced back to a microscopic accident. It happened just once, 2 billion years ago — and never again since. It is, perhaps, the greatest fluke of all time.
