Quotes by Steven Pinker

People who are depressed at the thought that all our motives are selfish are [confused]. They have mixed up ultimate causation (why something evolved by natural selection) with proximate causation (how the entity works here and now). [A] good way to understand the logic of natural selection is to imagine that genes are agents with selfish motives. [T]he genes have metaphorical motives — making copies of themselves — and the organisms they design have real motives. But they are not the same motives. Sometimes the most selfish thing a gene can do is wire unselfish motives into a human brain — heartfelt, unstinting, deep-in-the-marrow unselfishness. The love of children (who carry ones genes into posterity), a faithful spouse (whose genetic fate is identical to ones own), and friends and allies (who trust you if youre trustworthy) can be bottomless and unimpeachable as far as we humans are concerned (proximate level), even if it is metaphorically self-serving as far as the genes are concerned (ultimate level). Combine this with the common misconception that the genes are a kind of essence or core of the person, and you get a mongrel of Dawkins and Freud: the idea that the metaphorical motives of the genes are the deep, unconscious, ulterior motives of the person. That is an error.

At first happiness might seem like just desserts for biological fitness (more accurately, the states that would have led to fitness in the environment in which we evolved). We are happier when we are healthy, well-fed, comfortable, safe, prosperous, knowledgeable, respected, non-celibate, and loved. Compared to their opposites, these objects of striving are conducive to reproduction. The function of happiness would be to mobilize the mind to seek the keys to Darwinian fitness. When we are unhappy, we work for the things that make us happy; when we are happy, we keep the status quo. The problem is, how much fitness is worth striving for?

Can reason lead us in directions that are good or decent or moral? After all, you pointed out that reason is just a means to an end, and the end depends on the reasoners passions. Reason can lay out a road map to peace and harmony if the reasoner wants peace and harmony, but it can also lay out a road map to conflict and strife if the reasoner delights in conflict and strife. Can reason force the reasoner to want less cruelty and waste?

Reason is overrated. Many pundits have argued that a good heart and steadfast moral clarity are superior to triangulations of overeducated policy wonks, like the best and brightest and that dragged us into the quagmire of Vietnam. And wasnt it reason that gave us the means to despoil the planet and threaten our species with weapons of mass destruction? In this way of thinking, its character and conscience, not cold-hearted calculation, that will save us. Besides, a human being is not a brain on a stick. My fellow psychologists have shown that were led by our bodies and our emotions and use our puny powers of reason merely to rationalize our gut feelings after the fact

Reason is up to these demands because it is an open-ended combinatorial system, an engine for generating an unlimited number of new ideas. Once it is programmed with a basic self-interest and an ability to communicate with others, its own logic will impel it, in the fullness of time, to respect the interests of ever-increasing numbers of others. It is reason too that can always take note of the shortcomings of previous exercises of reasoning, and update and improve itself in response. And if you detect a flaw in this argument, it is reason that allows you to point it out and defend an alternative.

Of course genes can’t pull the levers of our behavior directly. But they affect the wiring and workings of the brain, and the brain is the seat of our drives, temperaments and patterns of thought. Each of us is dealt a unique hand of tastes and aptitudes, like curiosity, ambition, empathy, a thirst for novelty or for security, a comfort level with the social or the mechanical or the abstract. Some opportunities we come across click with our constitutions and set us along a path in life.

Hobbess analysis of the causes of violence, borne out by modern data on crime and war, shows that violence is not a primitive, irrational urge, nor is it a pathology except in the metaphorical sense of a condition that everyone would like to eliminate. Instead, it is a near-inevitable outcome of the dynamics of self-interested, rational social organisms.

Organisms are selected to deploy violence only in circumstances where the expected benefits outweigh the expected costs.

we enjoy the peace we find today because people in past generations were appalled by the violence in their time and worked to reduce it, and so we should work to reduce the violence that remains in our time.

The 21st century has certainly seen the rape of women in wartime, but it has long been treated as an atrocious war crime, which most armies try to prevent and the rest deny and conceal. But for the heroes of the Iliad, female flesh was a legitimate spoil of war: women were to be enjoyed, monopolized, and disposed of at their pleasure. Menelaus launches the Trojan War when his wife, Helen, is abducted. Agamemnon brings disaster to the Greeks by refusing to return a sex slave to her father, and when he relents, he appropriates one belonging to Achilles, later compensating him with twenty-eight replacements. Achilles, for his part, offers this pithy description of his career: “I have spent many sleepless nights and bloody days in battle, fighting men for their women.”11 When Odysseus returns to his wife after twenty years away, he murders the men who courted her while everyone thought he was dead, and when he discovers that the men had consorted with the concubines of his household, he has his son execute the concubines too.

God, who is omnipotent, could have softened Pharaoh’s heart, but he hardens it instead, which gives him a reason to afflict every Egyptian with painful boils and other miseries before killing every one of their firstborn sons. (The word Passover alludes to the executioner angel’s passing over the households with Israelite firstborns.) God follows this massacre with another one when he drowns the Egyptian army as they pursue the Israelites across the Red Sea. The Israelites assemble at Mount Sinai and hear the Ten Commandments, the great moral code that outlaws engraved images and the coveting of livestock but gives a pass to slavery, rape, torture, mutilation, and genocide of neighboring tribes. The Israelites become impatient while waiting for Moses to return with an expanded set of laws, which will prescribe the death penalty for blasphemy, homosexuality, adultery, talking back to parents, and working on the Sabbath. To pass the time, they worship a statue of a calf, for which the punishment turns out to be, you guessed it, death. Following orders from God, Moses and his brother Aaron kill three thousand of their companions.

But in Hebrew scripture David is not just the “sweet singer of Israel,” the chiseled poet who plays a harp and composes the Psalms. After he makes his name by killing Goliath, David recruits a gang of guerrillas, extorts wealth from his fellow citizens at swordpoint, and fights as a mercenary for the Philistines. These achievements make Saul jealous: the women in his court are singing, “Saul has killed by the thousands, but David by the tens of thousands.” So Saul plots to have him assassinated.19 David narrowly escapes before staging a successful coup. When David becomes king, he keeps up his hard-earned reputation for killing by the tens of thousands. After his general Joab “wasted the country of the children of Ammon,” David “brought out the people that were in it, and cut them with saws, and with harrows of iron, and with axes.” 20 Finally he manages to do something that God considers immoral: he orders a census. To punish David for this lapse, God kills seventy thousand of his citizens.

People today think of the world as a uniquely dangerous place. It’s hard to follow the news without a mounting dread of terrorist attacks, a clash of civilizations, and the use of weapons of mass destruction. But we are apt to forget the dangers that filled the news a few decades ago, and to be blasé about the good fortune that so many of them have fizzled out.

One-on-one revenge was common in foraging societies, and kin-against-kin blood feuds were common in tribal societies that had not been pacified by a colonial or national government, particularly if they had an exaggerated culture of manly honor.

The violence of a lower-class man may indeed express rage, but it is aimed not at society but at the asshole who scraped his car and dissed him in front of a crowd.

Educated people, of course, know that perception, cognition, language, and emotion are rooted in the brain. But it is still tempting to think of the brain as it was shown in old educational cartoons, as a control panel with gauges and levers operated by a user — the self, the soul, the ghost, the person, the “me.” But cognitive neuroscience is showing that the self, too, is just another network of brain systems. [C]ognitive neuroscientists have not only exorcised the ghost but have shown that the brain does not even have a part that does exactly what the ghost is supposed to do: review all the facts and make a decision for the rest of the brain to carry out. Each of us feels that there is a single “I” in control. But that is an illusion that the brain works hard to produce, like the impression that our visual fields are rich in detail from edge to edge. The brain does have supervisory systems in the prefrontal lobes and anterior cingulate cortex, which can push the buttons of behavior and override habits and urges. But those systems are gadgets with specific quirks and limitations; they are not implementations of the rational free agent traditionally identified with the soul or the self.

In hermetic isolation, all kinds of bizarre and toxic ideas can fester. Sunlight is the best disinfectant, and exposing a bad idea to the critical glare of other minds provides at least a chance that it will wither and die.

Why give a robot an order to obey orders—why arent the original orders enough? Why command a robot not to do harm—wouldnt it be easier never to command it to do harm in the first place? Does the universe contain a mysterious force pulling entities toward malevolence, so that a positronic brain must be programmed to withstand it? Do intelligent beings inevitably develop an attitude problem? (…) Now that computers really have become smarter and more powerful, the anxiety has waned. Todays ubiquitous, networked computers have an unprecedented ability to do mischief should they ever go to the bad. But the only mayhem comes from unpredictable chaos or from human malice in the form of viruses. We no longer worry about electronic serial killers or subversive silicon cabals because we are beginning to appreciate that malevolence—like vision, motor coordination, and common sense—does not come free with computation but has to be programmed in. (…) Aggression, like every other part of human behavior we take for granted, is a challenging engineering problem!

Lewis Richardson wrote that his quest to analyze peace with numbers sprang from two prejudices. As a Quaker, he believed that the moral evil in war outweighs the moral good, although the latter is conspicuous. As a scientist, he thought there was too much moralizing about war and not enough knowledge. For indignation is so easy and satisfying a mood that it is apt to prevent one from attending to any facts that oppose it. If the reader should object that I have abandoned ethics for the false doctrine that tout comprendre cest tout pardonner [to understand all is to forgive all], I can reply that it is only a temporary suspense of ethical judgment, made because beaucoup condamner cest peu comprendre [to condemn much is to understand little]. (p. 200)

Many moral advances have taken the form of a shift in sensibilities that made an action seem more ridiculous than sinful, such as dueling, bullfighting, and jingoistic war. And many effective social critics, such as Swift, Johnson, Voltaire, Twain, Oscar Wilde, Bertrand Russell, Tom Lehrer, and George Carlin have been smart-ass comedians rather than thundering prophets. What in our psychology allows the joke to be mightier than the sword?Humor works by confronting an audience with an incongruity, which may be resolved by switching to another frame of reference. And in that alternative frame of reference, the butt of the joke occupies a lowly or undignified status. ...Humor with a political or moral agenda can stealthily challenge a relational model that is second nature to an audience by forcing them to see that it leads to consequences that the rest of their minds recognize as absur
