I don't consider myself to be that radical a thinker.

But in most cases even the possibility that the correlations reflect shared genes is taboo.

Many artists and scholars have pointed out that ultimately art depends on human nature.

So no, it's not all in the genes, but what isn't in the genes isn't in the family environment either. It can't be explained in terms of the overall personalities or the child-rearing practices of parents.

Art works because it appeals to certain faculties of the mind. Music depends on details of the auditory system, painting and sculpture on the visual system. Poetry and literature depend on language.

Most intellectuals today have a phobia of any explanation of the mind that invokes genetics.

There has to be innate circuitry that does the learning, that creates the culture, that acquires the culture, and that responds to socialization.

By exploring the political and moral colorings of discoveries about what makes us tick, we can have a more honest science and a less fearful intellectual milieu.

Parents provide their children with genes as well as an environment, so the fact that talkative parents have kids with good language skills could simply mean that and that the same genes that make parents talkative make children articulate.

The great appeal of the doctrine that the mind is a blank slate is the simple mathematical fact that zero equals zero.

People today sometimes get uncomfortable with empirical claims that seem to clash with their political assumptions, often because they haven't given much thought to the connections.

The connections I draw between human nature and political systems in my new book, for example, were prefigured in the debates during the Enlightenment and during the framing of the American Constitution.

As many political writers have pointed out, commitment to political equality is not an empirical claim that people are clones.

Why are empirical questions about how the mind works so weighted down with political and moral and emotional baggage?

Personality and socialization aren't the same thing.

I think this confusion leads intellectuals and artists themselves to believe that the elite arts and humanities are a kind of higher, exalted form of human endeavor.

But the newest research is showing that many properties of the brain are genetically organized, and don't depend on information coming in from the senses.

My opinions about human nature are shared by many psychologists, linguists, and biologists, not to mention philosophers and scholars going back centuries.

Evolutionary psychology is one of four sciences that are bringing human nature back into the picture.

Why do people believe that there are dangerous implications of the idea that the mind is a product of the brain, that the brain is organized in part by the genome, and that the genome was shaped by natural selection?

'Capitalism' is a dirty word for many intellectuals, but there are a number of studies showing that open economies and free trade are negatively correlated with genocide and war.

20th-century totalitarian movements were no more defined by a rejection of Judeo-Christianity than they were defined by a rejection of astrology, alchemy, Confucianism, Scientology, or any of hundreds of other belief systems.

A decent government with an effective, but not gratuitously violent, police force and a fair court system are essential. This deters and incapacitates psychopaths, bullies and hotheads - and if it earns the confidence of the people, they don't have to become violent in self-defence.

A hostility to modernity is shared by ideologies that have nothing else in common - a nostalgia for moral clarity, small-town intimacy, family values, primitive communism, ecological sustainability, communitarian solidarity, or harmonies with the rhythms of nature.

A word is an arbitrary label - that's the foundation of linguistics. But many people think otherwise. They believe in word magic: that uttering a spell, incantation, curse, or prayer can change the world. Don't snicker: Would you ever say, 'Nothing has gone wrong yet' without looking for wood to knock?

Academics lack perspective. In a debate on whether the world is round, they would argue, 'No,' because it's an oblate spheroid. They suffer from 'the curse of knowledge': the inability to imagine what it's like not to know something that they know.

All of the violence that doesn't occur doesn't get reported on the news.

All our behaviours are a result of neurophysiological activity in the brain.

All our behaviours are a result of neurophysiological activity in the brain. There is no reason to believe there is any magic going on.

America had, for one thing, lived in anarchy for - until much more recently than Europe. We had the Wild West, where the cliche of the cowboy movies was the nearest sheriff is 90 miles away, and so you had to pack a gun and defend yourself.

An enormous amount of scientific language is metaphorical. We talk about a genetic code, where code originally meant a cipher; we talk about the solar system model of the atom as though the atom were like a sun and moon and planets.

An eye for beauty locks onto faces that show signs of health and fertility - just as one would predict if it had evolved to help the beholder find the fittest mate.

Anything that makes it easier to imagine trading places with someone else increases your moral consideration for that other person.

As a graduate student, I wrote a long paper connecting the dots between mathematical models of learning and language development in children. It was published in a major journal.

As every student in Philosophy 101 learns, nothing can force me to believe that anyone except me is conscious. This power to deny that other people have feelings is not just an academic exercise but an all-too-common vice, as we see in the long history of human cruelty.

As individual people, embedded in our daily lives, of course we're interested in what makes one person different from another. We've got to hire one person and not another, marry one person and not another.

As long as your ideology identifies the main source of the world's ills as a definable group, it opens the world up to genocide.

As women are empowered, violence can come down, for a number of reasons. By all measures, men are the more violent gender.

Astrology had an important role in the ancient world. You can't understand many things unless you know something about astrology - the plays of Shakespeare and so on.

Broadly speaking, the Southern and Western desert and mountain states will vote for the candidate who endorses an aggressive military, a role for religion in public life, laissez-faire economic policies, private ownership of guns and relaxed conditions for using them, less regulation and taxation, and a valorization of the traditional family.

By all measures men are the more violent gender.

Climate change could produce a lot of misery and waste without necessarily leading to large-scale armed conflict, which depends more on ideology and bad governance than on resource scarcity.

Cognitive psychology has shown that the mind best understands facts when they are woven into a conceptual fabric, such as a narrative, mental map, or intuitive theory. Disconnected facts in the mind are like unlinked pages on the Web: They might as well not exist.

Cognitive psychology tells us that the unaided human mind is vulnerable to many fallacies and illusions because of its reliance on its memory for vivid anecdotes rather than systematic statistics.

Commerce is a noble profession, and Jews should get over any self-hatred they might harbor from contemplating the capitalist spirit of diaspora Judaism.

Commerce, trade and exchange make other people more valuable alive than dead, and mean that people try to anticipate what the other guy needs and wants. It engages the mechanisms of reciprocal altruism, as the evolutionary biologists call it, as opposed to raw dominance.

Consciousness surely does not depend on language. Babies, many animals, and patients robbed of speech by brain damage are not insensate robots; they have reactions like ours that indicate that someone's home.

Consciousness turns out to consist of a maelstrom of events distributed across the brain. These events compete for attention, and as one process outshouts the others, the brain rationalizes the outcome after the fact and concocts the impression that a single self was in charge all along.
