“Da Shi, have you ever … considered certain ultimate philosophical questions? For example, where does Man come from? Where does Man go? Where does the universe come from? Where does the universe go? Et cetera.” “Nope.” “Never?” “Never.” “You must see the stars. Aren’t you awed and curious?” “I never look at the sky at night.” “How is that possible? I thought you often worked the night shift?” “Buddy, when I work at night, if I look up at the sky, the suspect is going to escape.” “We really have nothing to say to each other. All right. Drink!” “To be honest, even if I were to look at the stars in the sky, I wouldn’t be thinking about your philosophical questions. I have too much to worry about! I gotta pay the mortgage, save for the kid’s college, and handle the endless stream of cases.… I’m a simple man without a lot of complicated twists and turns. Look down my throat and you can see out my ass. Naturally, I don’t know how to make my bosses like me. Years after being discharged from the army, my career is going nowhere. If I weren’t pretty good at my job, I would have been kicked out a long time ago.… You think that’s not enough for me to worry about? You think I’ve got the energy to gaze at stars and philosophize?” “You’re right. All right, drink up!” “But, I did indeed invent an ultimate rule.” “Tell me.” “Anything sufficiently weird must be fishy.” “What … what kind of crappy rule is that?” “I’m saying that there’s always someone behind things that don’t seem to have an explanation.” “If you had even basic knowledge of science, you’d know it’s impossible for any force to accomplish the things I experienced. Especially that last one. To manipulate things at the scale of the universe—not only can you not explain it with our current science, I couldn’t even imagine how to explain it outside of science. It’s more than supernatural. It’s super-I-don’t-know-what.…” “I’m telling you, that’s bullshit. I’ve seen plenty of weird things.” “Then tell me what I should do next.” “Keep on drinking. And then sleep.” “Fine.”

The Three-Body Problem

Cixin Liu and Ken Liu

The one-armed woman said, “There was a movie called Maple recently. I don’t know if you’ve seen it. At the end, an adult and a child stand in front of the grave of a Red Guard who had died during the faction civil wars. The child asks the adult, ‘Are they heroes?’ The adult says no. The child asks, ‘Are they enemies?’ The adult again says no. The child asks, ‘Then who are they?’ The adult says, ‘History.’” “Did you hear that?” The thickset woman waved an arm excitedly at Ye. “History! History! It’s a new age now. Who will remember us? Who will think of us, including you? Everyone will forget all this completely!” The three old Red Guards departed, leaving only Ye on the exercise grounds. More than a dozen years ago, on that rainy afternoon, she had stood alone here as well, gazing at her dead father. The old Red Guard’s final remark echoed endlessly in her mind.…

The Three-Body Problem

Cixin Liu and Ken Liu

It’s easy to recognize two reasons why my impression that New Guineans are smarter than Westerners may be correct. First, Europeans have for thousands of years been living in densely populated societies with central governments, police, and judiciaries. In those societies, infectious epidemic diseases of dense populations (such as smallpox) were historically the major cause of death, while murders were relatively uncommon and a state of war was the exception rather than the rule. Most Europeans who escaped fatal infections also escaped other potential causes of death and proceeded to pass on their genes. Today, most live-born Western infants survive fatal infections as well and reproduce themselves, regardless of their intelligence and the genes they bear. In contrast, New Guineans have been living in societies where human numbers were too low for epidemic diseases of dense populations to evolve. Instead, traditional New Guineans suffered high mortality from murder, chronic tribal warfare, accidents, and problems in procuring food. Intelligent people are likelier than less intelligent ones to escape those causes of high mortality in traditional New Guinea societies. However, the differential mortality from epidemic diseases in traditional European societies had little to do with intelligence, and instead involved genetic resistance dependent on details of body chemistry. For example, people with blood group B or O have a greater resistance to smallpox than do people with blood group A. That is, natural selection promoting genes for intelligence has probably been far more ruthless in New Guinea than in more densely populated, politically complex societies, where natural selection for body chemistry was instead more potent. Besides this genetic reason, there is also a second reason why New Guineans may have come to be smarter than Westerners. Modern European and American children spend much of their time being passively entertained by television, radio, and movies. In the average American household, the TV set is on for seven hours per day. In contrast, traditional New Guinea children have virtually no such opportunities for passive entertainment and instead spend almost all of their waking hours actively doing something, such as talking or playing with other children or adults. Almost all studies of child development emphasize the role of childhood stimulation and activity in promoting mental development, and stress the irreversible mental stunting associated with reduced childhood stimulation. This effect surely contributes a non-genetic component to the superior average mental function displayed by New Guineans.
