History and man made each other.

A genius is produced not by a woman’s womb but by a man’s efforts.

Ants have a powerful caste system. A colony typically contains ants that carry out radically different roles and have markedly different body structures and behaviors. These roles, Reinberg learned, are often determined not by genes but by signals from the physical and social environment. 'Sibling ants, in their larval stage, become segregated into the different types based on environmental signals,' he said. 'Their genomes are nearly identical, but the way the genes are used—turned on or off, and kept on or off—must determine what an ant "becomes." It seemed like a perfect system to study epigenetics. And so Shelley and I caught a flight to Arizona to see Jürgen Liebig, the ant biologist, in his lab.' The collaboration between Reinberg, Berger, and Liebig has been explosively successful—the sort of scientific story ('two epigeneticists walk into a bar and meet an entomologist') that works its way into a legend. Carpenter ants, one of the species studied by the team, have elaborate social structures, with queens (bullet-size, fertile, winged), majors (bean-size soldiers who guard the colony but rarely leave it), and minors (nimble, grain-size, perpetually moving foragers). In a recent, revelatory study, researchers in Berger’s lab injected a single dose of a histone-altering chemical into the brains of major ants. Remarkably, their identities changed; caste was recast. The major ants wandered away from the colony and began to forage for food. The guards turned into scouts. Yet the caste switch could occur only if the chemical was injected during a vulnerable period in the ants’ development. [...] The impact of the histone-altering experiment sank in as I left Reinberg’s lab and dodged into the subway. [...] All of an ant’s possible selves are inscribed in its genome. Epigenetic signals conceal some of these selves and reveal others, coiling some, uncoiling others. The ant chooses a life between its genes and its epigenes—inhabiting one self among its incipient selves.

Babies are never suicidal. Hard lives, not hard boiled eggs do that.

Day after day, more and more medications are prescribed for depression and addiction, assuming that these things run in our blood, when really they run in our patterns of awareness.

Needs are imposed by nature. Wants are sold by society.

I'm probably not smart enough to appreciate all your glory. Must be because of my genes. Yes, I'm definitely struggling to appreciate it right now.

Most of us experience gender conditioning so young—research shows it begins in infancy—that we misunderstand the relationship between nature and nurture, culture and biology, fitting in and being oneself.

No body wishes more than I do to see such proofs as you exhibit, that nature has given to our black brethren, talents equal to those of the other colors of men, and that the appearance of a want of them is owing merely to the degraded condition of their existence, both in Africa & America.

She's a she-wolf. Her nature demands she's dominated, even if she tries to fight it. She'll listen to an amount of force – positive force, not negative force. But leave the run wide open with no boundaries and she won't listen to you at all. All she'll listen to is the call of freedom, even if it leads her straight into a trap. Stop thinking like a human. She's a wolf.

No expert was born an expert.

Sandra stood by, quietly amused: she wore a sugar pink track suit with matching plastic hairslides in the shape of elephants. Edward could see quite clearly behind her shoulder, like the aura visible to spiritualists, the woman she would be in thirty years time. There is probably nothing to be done about people, he thought, nothing at all, nor ever has been: processed, from the cradle to the grave. Most neither know nor care, which makes it worse.

One brain’s blueprint may promote joy more readily than most; in another, pessimism reigns. Whether happiness infuses or eludes a person depends, in part, on the DNA he has chanced to receive. (152)

Sometimes, I think that thugs learn to be brutal because people have been cruel to them. If you want to make a dog vicious, all you have to do is beat him for no reason. It's the same with a kid, only easier. You don't even need to beat him. Jeering and mocking him is enough.

The brain is heavily influenced by genes. But from birth through young adulthood, the part of the human brain that most defines us is less a product of the genes with which you started life than of what life has thrown at you. Because it is the last to mature, by definition the frontal cortex is the brain region least constrained by genes and most sculpted by experience. This must be so, to be the supremely complex social species that we are. Ironically, it seems that the genetic program of human brain development has evolved to, as much as possible, free the frontal cortex from genes.

Virginity comes standard. A good head is earned.

You inherit your environment just as much as your genes.

We must not only observe but listen to the sound of nature.

While genes are pivotal in establishing some aspects of emotionality, experience plays a central role in turning genes on and off. DNA is not the heart’s destiny; the genetic lottery may determine the cards in your deck, but experience deals the hand you can play. Scientists have proven, for example, that good mothering can override a disadvantageous temperament.(152)
