“The only thing that really matters in life are your relationships to other people.” After nearly 75 years, the only consistent finding comes right out of It’s a Wonderful Life. Successful friendships, the messy bridges that connect friends and family, are what predict people’s happiness as they hurtle through life…
In fact, some evolutionary biologists believe this is why morning sickness still persists in human pregnancies. Morning sickness, which can last the entire day (and, for some women, the entire pregnancy), makes a woman stick to a bland, boring diet—if she eats much at all. This avoidance strategy would have kept our…
I may hand over to men their fortunes, now their understanding is emancipated and come as it were of age; whence there cannot but follow an improvement in man's estate and an enlargement of his power over nature. For man by the fall fell at the same time from his state of innocency and from his dominion over creation…
Now the true and lawful goal of the sciences is none other than this: that human life be endowed with new discoveries and powers. But of this the great majority have no feeling, but are merely hireling and professorial; except when it occasionally happens that some workman of acuter wit and covetous of honor applies…
The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises…
Piaget had his own way of assessing brain maturation during this period, using his now-famous "conservation" tasks, try this one out on your tour-to-eight-year-old: fill two identical short, squat glasses with equal volumes of water, and ask your child, "Do the two glasses contain the same amount of water, or does one…
Like many other areas of development, memory generally matures more rapidly in girls than boys. Beginning in the womb, female fetuses are known to habituate to auditory stimuli about two weeks earlier than males. After birth, they are more advanced at visual habituation. Toward the end of the first year, girls are…
As to religion, I hold it to be the indispensable duty of all government, to protect all conscientious professors thereof, and I know of no other business which government hath to do therewith, Let a man throw aside that narrowness of soul, that selfishness of principle, which the niggards of all professions are so…
Spitz showed that early nurturing and stimulation are essential to child development, and he was not alone in this view. At the time, the field of psychology was dominated by the theory of "behaviorism," which proposed that all our actions, from the simplest smile to the most sophisticated chess move, are learned…
We think there are very strong similarities between some particular types of early learning—learning about objects and about the mind, in particular—and scientific theory change. In fact, we think they are not just similar but identical. We don't just think that the baby computers have the same general structure as…
The real obstetrical dilemma came long after Lucy and her colleagues became extinct, when there was a sudden upsurge in brain expansion. About 1.5 million years ago, die adult hominid brain went from the Australopithecine size of 400 cubic centimeters to 750 cubic centimeters in a species called Homo habilis, the…
Archaeologists have discovered that since the Pleistocene, humans lave always suckled infants for several years. Using biochemical analysis given human population when its children moved from breast milk to other foods. In one group of skeletons from South Dakota dated between 5500-2000 b.c., children were apparently…
Crying is the earliest and most compelling of infant signals," writes Ronald Barr, and surely there is no sound on earth more piercing than the cry of an infant. The ability to cry was hard-wired into human babies long ago as a potent signal to get adult attention. Like other primates, human infants needed to be able…
We lay and looked up at the sky and the millions of stars that blazed in darkness. The night was so still that we could hear the buoy on the ledges out beyond the mouth of the bay. Once or twice a word spoken by someone on the far shore was carried across the clear air. A few lights burned in the cottages. Otherwise…
Anthropocentrism isn’t just a faulty value system, but also a faulty way of understanding the world. Modern science has shown this, displacing human beings from the center of the universe, opening up immense vistas of space and time, telling a story of life in which chance, not destiny, has raised an unusual primate…
A crushing backload, indeed: fiddlehead ferns, downy woodpecker, pickerel, granite flake. Canada mayflower, moonrise, bluebirds, spring peepers, monarch butterflies, glacial scratches on bedrock, and, of course, the human history of my path, which in its transformations over the centuries encapsulates in many…
A stress-related decline in the sex ratio is no anomaly, but a biological mechanism that evolved to keep the species going, according to Ralph Catalano, professor of public health at the University of California, Berkeley. “From an evolutionary perspective, in stressful eras it’s a smarter bet to have a female child…
When I was a fairly precocious young man I became thoroughly impressed with the futility of the hopes and strivings that chase most men restlessly through life. Moreover, I soon discovered the cruelty of that chase, which in those years was much more carefully covered up by hypocrisy and glittering words than is the…
Physician's Oath At the time of being admitted as a member of the medical profession: I solemnly pledge myself to consecrate my life to the service of humanity; I will give to my teachers the respect and gratitude which is their due; I will practice my profession with conscience and dignity; the health of my patient…
It would be desirable for the government to authorize people to go into the factories and shops, to see the craftsmen at their work, to question them, to draw the tools, the machines, and even the premises. There are special circumstances when craftsmen are so secretive about their techniques that the shortest way of…
