 We Are Lucky Because We are Going to Die

We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Arabia. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively exceeds the set of actual people. In the teeth ...

 A Poem to Teach a Child

We live in an age of information. Too much information can swamp the boat of wonder, especially for a child. From a science book we might learn that a flying bat might snap up 15 insects per minute, or that the frequency of its squeal can range as high as 50,000 cycles per second. Useful information, yes. But consider the information in this poem from Randall Jarrell's "The Bat Poet": A bat is born Naked and blind and pale. His mother makes a pocket of her tail And catches him. He cling...

 We Are Made of Star Stuff

The fate of individual human beings may not now be connected in a deep way with the rest of the universe, but the matter out of which each of us is made is intimately tied to processes that occurred immense intervals of time and enormous distances in space away from us. Our Sun is a second- or third-generation star. All of the rocky and metallic material we stand on, the iron in our blood, the calcium in our teeth, the carbon in our genes were produced billions of years ago in the interior of...

 Hen's Teeth

Some atavisms can be produced in the laboratory. The most amazing of these is that paragon of rarity, hen’s teeth. In 1980, E. J. Kollar and C. Fisher at the University of Connecticut combined the tissues of two species, grafting the tissue lining the mouth of a chicken embryo on top of tissue from the jaw of a developing mouse. Amazingly, the chicken tissue eventually produced tooth-like structures, some with distinct roots and crowns! Since the underlying mouse tissue alone could not prod...

 The Eternal Conflict Between Enlightenment and Ignorance

‘There are two great powers,” the man said, “and they’ve been fighting since time began. Every advance in human life, every scrap of knowledge and wisdom and decency we have has been torn by one side from the teeth of the other. Every little increase in human freedom has been fought over ferociously between those who want us to know more and be wiser and stronger, and those who want us to obey and be humble and submit.

 Skinner and Freud's View of Child Learning

The theories that did dominate psychology, especially in America, were Freudianism and the behaviorism of psychologists like B. F. Skinner. Both theories had lots of things to say about young children. But like Aristotle with the teeth, neither Freud nor Skinner took the step of doing systematic experiments with children or babies. Freud largely relied on inferences from the behavior of neurotic adults, and Skinner on inferences from the behavior of only slightly less neurotic rats. And like ...
