Behavioral science is not for sissies.

The doctrine of the sacredness of the soul sounds vaguely uplifting, but in fact is highly malignant. It discounts life on earth as just a temporary phase that people pass through, indeed, an infinitesimal fraction...

Some people think that evolutionary psychology claims to have discovered that human nature is selfish and wicked. But they are flattering the researchers and anyone who would claim to have discovered the opposite. No one...

An ideology can provide a satisfying narrative that explains chaotic events and collective misfortunes in a way that flatters the virtue and competence of believers, while being vague or conspiratorial enough to withstand skeptical scrutiny.

The foundation of individual rights is the assumption that people have wants and needs and are authorities on what those wants and needs are. If people’s stated desires were just some kind of erasable inscription...

Once we have isolated the computational and neurological correlates of access-consciousness, there is nothing left to explain. It’s just irrational to insist that sentience remains unexplained after all the manifestations of sentience have been accounted...

Equality is not the empirical claim that all groups of humans are interchangeable; it is the moral principle that individuals should not be judged or constrained by the average properties of their group.

Why should the spread of ideas and people result in reforms that lower violence? There are several pathways. The most obvious is a debunking of ignorance and superstition. A connected and educated populace, at least...

We should expose whatever ends are harmful and whatever ideas are false, and not confuse the two.

People do more for their fellows than return favors and punish cheaters. They often perform generous acts without the slightest hope for payback ranging from leaving a tip in a restaurant they will never visit...

Institutionalized torture in Christendom was not just an unthinking habit; it had a moral rationale. If you really believe that failing to accept Jesus as one’s savior is a ticket to fiery damnation, then torturing...

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....

The mind is not designed to grasp the laws of probability, even though the laws rule the universe.

The Rights Revolutions too have given us ideals that educated people today take for granted but that are virtually unprecedented in human history, such as that people of all races and creeds have equal rights,...

Feminism as a movement for political and social equity is important, but feminism as an academic clique committed to eccentric doctrines about human nature is not. Eliminating discrimination against women is important, but believing that...

The stuff of life turned out to be not a quivering, glowing, wondrous gel but a contraption of tiny jigs, springs, hinges, rods, sheets, magnets, zippers, and trapdoors, assembled by a data tape whose information...

Sex and excretion are reminders that anyone’s claim to round-the-clock dignity is tenuous. The so-called rational animal has a desperate drive to pair up and moan and writhe.

Hobbes’s 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...

Nothing invests life with more meaning than the realisation that every moment of sentience is a precious gift

The indispensability of reason does not imply that individual people are always rational or are unswayed by passion and illusion. It only means that people are capable of reason, and that a community of people...

I believe that the rape-is-not-about-sex doctrine will go down in history as an example of extraordinary popular delusions and the madness of crowds. It is preposterous on the face of it, does not deserve its...

The typical imperative from biology is not “Thou shalt… ,” but “If … then … else.

The idea that boys want to sleep with their mothers strikes most men as the silliest thing they have ever heard. Obviously, it did not seem so to Freud, who wrote that as a boy...

Since violence is largely a male pastime, cultures that empower women tend to move away from the glorification of violence and are less likely to breed dangerous subcultures of rootless young men.

More to the point, what was the lesson that the first Christians drew from crucifixion? Today such a barbarity might galvanize people into opposing brutal regimes, or demanding that such torture never again be inflicted...

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 reasoner’s passions....

Many textbooks point out that no animal has evolved wheels and cite the fact as an example of how evolution is often incapable of finding the optimal solution to an engineering problem. But it is...

As technology accumulates and people in more parts of the planet become interdependent, the hatred between them tends to decrease, for the simple reason that you can’t kill someone and trade with him too.

The scriptures present a God who delights in genocide, rape, slavery, and the execution of nonconformists, and for millennia those writings were used to rationalize the massacre of infidels, the ownership of women, the beating...

I think about how language works so I can best explain how language works.

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...

Evolutionarily speaking, there is seldom any mystery in why we seek the goals we seek — why, for example, people would rather make love with an attractive partner than get a slap on the belly...

The supposedly immaterial soul, we now know, can be bisected with a knife, altered by chemicals, started or stopped by electricity, and extinguished by a sharp blow or by insufficient oxygen.

Challenge a person’s beliefs, and you challenge his dignity, standing, and power. And when those beliefs are based on nothing but faith, they are chronically fragile. No one gets upset about the belief that rocks...

Humans are so innately hardwired for language that they can no more suppress their ability to learn and use language than they can suppress the instinct to pull a hand back from a hot surface.

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...

It looks as if the offspring have eyes so that they can see well (bad, teleological, backward causation), but that’s an illusion. The offspring have eyes because their parents’ eyes did see well (good, ordinary,...

The doctrine of a soul that outlives the body is anything but righteous, because it necessarily devalues the lives we live on this earth.

It’s natural to think that living things must be the handiwork of a designer. But it was also natural to think that the sun went around the earth. Overcoming naive impressions to figure out how...

The universality of reason is a momentous realization, because it defines a place for morality. If I appeal to you do do something that affects me—to get off my foot, or not to stab me...

Why give a robot an order to obey orders—why aren’t the original orders enough? Why command a robot not to do harm—wouldn’t it be easier never to command it to do harm in the first...

Trivers, pursuing his theory of the emotions to its logical conclusion, notes that in a world of walking lie detectors the best strategy is to believe your own lies. You can’t leak your hidden intentions...

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,...

I am sometimes asked, “How do you know there won’t be a war tomorrow (or a genocide, or an act of terrorism) that will refute your whole thesis?” The question misses the point of this...

I think that communism was a major force for violence for more than 100 years, because it was built into its ideology—that progress comes through class struggle, often violent. It led to the widespread belief...

If the metaphors in everyday speech are a clue, then all of us associate blankness with virtue rather than with nothingness. Think of the moral connotations of the adjectives: clean, fair, immaculate, lily-white, pure, spotless,...

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.”...

A…reason we are so-so scientists is that our brains were shaped for fitness, not for truth. Sometimes truth is adaptive, but sometimes it is not.

Dear White Fella When I am born I’m black When I grow up I’m black When I am sick I’m black When I go out ina sun I’m black When I git cold I’m black...

Nature is a hanging judge,” goes an old saying. Many tragedies come from our physical and cognitive makeup. Our bodies are extraordinarily improbable arrangements of matter, with many ways for things to go wrong and...
