Three-and-a-half-month-old infants already seem to exhibit the other-race effect. In a study at the University of Kentucky, white babies were very good at distinguishing faces with 100 percent Caucasian features from faces that had been graphically morphed to include features that were 70 percent white and 30 percent Asian. They couldn’t do the reverse: They could not tell 100 percent Asian faces from those that were morphed to include 30 percent white features. In other words, they could detect small differences between white and not-quite-white faces, but not the same kinds of differences between Asian and not-quite-Asian faces. Lawrence A. Hirschfeld of the University of Michigan did some of the pioneering work on how early in life children begin to understand race. He showed children of ages three, four, and seven, a picture of “Johnny:” a chubby black boy in a police uniform, complete with whistle and toy gun. He then showed them pictures of adults who shared two of Johnny’s three main traits of race, body build, and uniform. Prof. Hirschfeld prepared all combinations—policemen who were fat but were white, thin black policemen, etc.—and asked the children which was Johnny’s daddy or which was Johnny all grown up. Even the three-year-olds were significantly more likely to choose the black man rather than the fat man or the policeman. They knew that weight and occupation can change but race is permanent. In 1996, after 15 years of studying children and race, Prof. Hirschfeld concluded: “Our minds seem to be organized in a way that makes thinking racially—thinking that the human world can be segmented into discrete racial populations—an almost automatic part of our mental repertoire.” When white preschoolers are shown racially ambiguous faces that look angry, they tend to say they are faces of blacks, but categorize happy faces as white. “These filters through which people see the world are present very early,” explained Andrew Baron of Harvard. Phyllis Katz, then a professor at the University of Colorado, studied young children for their first six years. At age three, she showed them photographs of other children and asked them whom they would like to have as friends. Eighty-six percent of white children chose photographs of white children. At age five and six, she gave children pictures of people and told them to sort them into two piles by any criteria they liked. Sixty-eight percent sorted by race and only 16 by sex. Of her entire six-year study Prof. Katz said, “I think it is fair to say that at no point in the study did the children exhibit the Rousseau type of color-blindness that many adults expect.
To many intellectuals such as Celsus, the whole idea of a ‘Creation myth’ was not only implausible but redundant. During this period in Rome, a popular and influential philosophical theory offered an alternative view. This theory – an Epicurean one – stated that everything in the world was made not by any divine being but by the collision and combination of atoms. According to this school of thought, these particles were invisible to the naked eye but they had their own structure and could not be cut (temno) into any smaller particles: they were a-temnos – ‘the uncuttable thing’: the atom. Everything that you see or feel, these materialists argued, was made up of two things: atoms and space ‘in which these bodies are and through which they move this way and that’. Even living creatures were made from them: humans were, as one (hostile) author summarized, not made by God but were instead nothing more than ‘a haphazard union of elements’. The distinct species of animals were explained by a form of proto-Darwinism. As the Roman poet and atomist Lucretius wrote, nature put forth many species. Those that had useful characteristics – the fox and its cunning, say, or the dog and its intelligence – survived, thrived and reproduced. Those creatures that lacked these ‘lay at the mercy of others for prey and profit . . . until nature brought that race to destruction’.
[...] true hedonic engineering, as distinct from mindless hedonism or reckless personal experimentation, can be profoundly good for our character. Character-building technologies can benefit utilitarians and non-utilitarians alike. Potentially, we can use a convergence of biotech, nanorobotics and information technology to gain control over our emotions and become better (post-)human beings, to cultivate the virtues, strength of character, decency, to become kinder, friendlier, more compassionate: to become the type of (post)human beings that we might aspire to be, but aren't, and biologically couldn't be, with the neural machinery of unenriched minds. Given our Darwinian biology, too many forms of admirable behaviour simply aren't rewarding enough for us to practise them consistently: our second-order desires to live better lives as better people are often feeble echoes of our baser passions.
