"[ Cup slams ]" "Noble:" "For the mentally ill, outside of asylums, there is no help." "Lederer:" "This is a period of time when there are no effective treatments, and physicians are desperate to provide help to individuals and to their families." "[ Sighs ]" "Noble:" "Moniz has a radical plan to cut into the brains of mental patients to alter their behavior -- a technique inspired by American research he's seen on monkeys." "It really is a very simple procedure." "He wants to sever the frontal lobes from the rest of the brain -- an operation now known as a prefrontal lobotomy." "There is some resistance to the blade, but with a firm hand, it goes in smoothly into the flesh of the brain, and then..." "Moniz's young colleague, Dr. Diogo Furtado, is fascinated." "That's incredible." "These are the frontal lobes of the brain." "And they're responsible for important tasks like decision-making, short-term memory, and aspects of your personality." "Now, you can survive without them, but without them, you're not really you." "So, what Moniz was trying to do is separate them from the rest of the brain." "And what were the results like?" "W-what I saw was extraordinary." "The monkeys lost all symptoms of frustration and anxiety." "He wasn't exactly sure why it happened, but it affected behavior." "It changed how they acted."

"This is a copy of Moniz's original leucotome -- a device that can be inserted through a hole drilled in a person's head, and then, once inside the brain, a plunger depressed and a cutting wire extended." "So, Moniz would take this instrument, insert it into the brain, and wouldn't exactly know how far to go." "But once he felt like he'd gone far enough, he would extend the cutting wire and rotate the tool." "But, of course, he was doing this all blind." "He couldn't see where he was, so he was quite literally taking a stab in the dark." "Noble:" "If lobotomy makes the insane less violent, there is no shortage of candidates for Moniz's knife."

"In the world of numbers, he is a genius." "In the world of people, mm, not so much." "Harman:" "So, George Price is a real-life cross between between Forrest Gump and Rain Man." "On the Forrest Gump side, he is always at the periphery of a great scientific or technological revolution, whether it's at the Manhattan Project working as a chemist on uranium enrichment, or at Bell Labs working on transistor research" "at the telecommunications revolution, or inventing computer-aided design for IBM." "On the Rain Man side, alongside his great brilliance, he's also a very strange human being -- not very good with people." "Ma'am." "Sorry, ma'am."

"Their marriage fails, and Price travels to London, searching for a new direction." "Keep up the good fight." "Bless you." "[ Sighs ]" "Price buries himself in London's many libraries, reading any scientific paper that attracts him." "He stumbles across a subject he's never considered before -- evolution." "Charles Darwin's theory of Natural Selection says that tiny differences between offspring can make one more likely to survive and reproduce than another." "So, for example, if you live in a region where resources become sparse and you have to climb trees to get food, those people who have good tree-climbing skills would be able to survive in those conditions," "whereas others who hadn't received those genes to allow them to climb the trees wouldn't." "Noble:" "Evolution is nothing new." "But Price finds a revolutionary paper by biologist William Hamilton." "It applies evolution not to the way our bodies work, but to the way we behave." "Reeve:" "Many evolutionary biologists consider this to be the most important paper in evolution in the last 100 years." "The genius of his idea was to apply natural-selection thinking, not just to physical characteristics such as body size, but also to social behavior among humans, as well." "Noble:" "Price analyzes Hamilton's argument that social behavior is carried in our genes, just like hair or eye color." "The paper attempts to solve a problem which has confounded every biologist since Darwin." "How can generous self-sacrifice, known as "altruism,"" "be a survival trait?" "Reeve:" "Here's the problem." "Imagine a gene that caused the ultimate self-sacrifice -- to give your life on behalf of somebody else." "Well, that gene is gonna disappear from the population, because the individual who possesses that gene, well, will obviously have no offspring." "Noble:" "Hamilton realizes that if you die saving a close relative, they might also be carrying the altruism gene and pass it on to the next generation as long as your death saves them." "For example, a mother who throws herself in front of a bus to save three offspring has her genes survive into the next generation, and has a bigger genetic advantage than if she had not thrown herself in front of the bus." "Noble:" "Price approaches the problem as a mathematician and develops a profoundly new set of equations to explain this idea." "He sends his work to Hamilton." "[ Telephone ringing ]" "Mr. Price?" "Yes." "This is Bill Hamilton." "Price points out shortcomings in Hamilton's paper." "I simply think that, uh, you've stumbled on the more basic axioms." "I mean, we all make mistakes, Professor Hamilton." "Please, call me Bill." "Um, okay." "Um..." "Bill." "I think you'll find that if you calculate covariance that..." "Price's math takes Hamilton's original ideas to a whole new level of sophistication." "Mr. Price, forgive me, but could you run that past me again?" "...problem of putting it..." "Harman:" "What Price comes up with is not a theory." "Rather, it is a theorem." "It is a mathematical truth, and it is always true under every and all circumstances, which is amazing." "Noble:" "Price's theorem mathematically proves Hamilton's idea that altruism is an evolutionary survival trick." "No matter how selfless a person seems, the math says genes are always in control." "You may think you're being generous, but in reality, your behavior is really to benefit your own genes." "When do you mean to publish?" "Um, nobody knows who I am, so..." "George -- may I call you "George"?" "You have to publish." "Ma'am." "Noble:" "And with Hamilton's help," "Price does get his work published..."

"It absolutely never happens in science." "And this, in a paper that purported to provide the answer to one of the greatest mysteries that science was looking at." "I guess." "Noble:" "George Price has found status, prestige, and, much to his own surprise, a lifelong friend." "But despite what his brilliant paper says," "Price sees pure altruism all around him." "Can these inspiring examples of human kindness really be explained away with math?" "He becomes troubled by the bleak notion that heroism results from the self-serving biology of our brains." "He wonders -- hopes, even -- that he's made an error." "Reeve:" "If the scientific theory is correct, it should always work where it's applied." "A single counter-example to the theory is enough to falsify it." "Price knew all this, so he reasoned that," ""All I have to do is find one counter-example to my own theory,"" "for example, by showing that there is a true case of unconditional altruism in humans, to blow his own theory out of the water." "Noble:" "To escape the implications of his own theory, he sets out to kill it... with kindness." "Noble:" "George Price's mathematical equation proves human kindness is just self-interest in disguise." "We have evolved to help others only because it helps our genes survive." "His scientific breakthrough reveals the world to be cold, predictable, out of our conscious control." "Then one day, the atheist mathematician has a revelation." "There is a God." "Harman:" "When he came up with his equation, he began contemplating what an enormous coincidence it was, because all the great minds, going back to Darwin, had been trying to crack this problem, and yet it was him -- a complete outsider " "who came up with this quite miraculous equation." "And so, thinking of other coincidences that had occurred to him during his lifetime -- very strange things, like four girlfriends by the name of "Anne,"" "and the last four digits of his phone number being 2399, which he interpreted to be just a moment before midnight." "It's the last chance to find God, and so forth." "And he multiplied all of these coincidences, and came up with an astronomical figure -- one divided by 10 to the 27th -- which meant that the chance that all of these things should have happened to him" "was infinitesimal, and yet they had all happened to him."
