value of the rejected goods

Americans today don't place a very high value on intellect. Our heroes are athletes, entertainers, and entrepreneurs, not scholars. Even our schools are where we send our children to get a practical education--not to pursue knowledge for the sake of knowledge. Symptoms of pervasive anti-intellectualism in our schools aren't difficult to find.

"Schools have always been in a society where practical is more important than intellectual," says education writer Diane Ravitch. "Schools could be a counterbalance. "Ravitch's latest book, Left Back: A Century of Failed School Reforms, traces the roots of anti-intellectualism in our schools, concluding they are anything but a counterbalance to the American distaste for intellectual pursuits.

But they could and should be. Encouraging kids to reject the life of the mind leaves them vulnerable to exploitation and control. Without the ability to think critically, to defend their ideas and understand the ideas of others, they cannot fully participate in our democracy. Continuing along this path, says writer Earl Shorris, "We will become a second rate country. We will have a less civil society."

"Intellect is resented as a form. of power or privilege," writes historian and professor Richard Hofstadter in Anti-Intellectualism in American Life, a Pulizer Prize winning book on the roots of anti-intellectualism in US politics, religion, and education. From the beginning of our history, says Hofstadter, our democratic and populist urges have driven us to reject anything that smells of elitism. Practicality, common sense, and native intelligence have been considered more noble qualities than anything you could learn from a book.

Ralph Waldo Emerson and other Transcendentalist philosophers thought schooling and rigorous book learning put unnatural restraints on children: "We are shut up in schools and college recitation rooms for 10 or 15 years and come out at last with a bellyful of words and do not know a thing. "Mark Twain's Huckleberry Finn exemplified American anti-intellectualism. Its hero avoids being civilized - going to school and learning to read - so he can preserve his innate goodness.

Intellect, according to Hofstadter, is different from native intelligence, a quality we reluctantly admire. Intellect is the critical, creative, and contemplative side of the mind. Intelligence seeks to grasp, manipulate, reorder, and adjust, while intellect examines, ponders, wonders, theorizes, criticizes, and imagines.

School remains a place where intellect is mistrusted. Hofstadter says our country's educational system is in the grips of people who "joyfully and militantly proclaim their hostility to intellect and their eagerness to identify with children who show the least intellectual promise."

The Scientific American Book of the Cosmos edited by David Levy, Macmillan, ￡20, ISBN 0333782933

Previous generations of scientists would have killed to know what we know. For the first time in history, we have a pretty good idea of the material content of the Universe, our position within it and how the whole thing came into being.

In these times of exploding knowledge there is a definite need to take stock and assemble what we know in a palatable (受欢迎的)form.(46)

The essays in The Scientific American Book of the Cosmos have been selected by David Levy, co-discoverer of Comet Shoemaker-Levy 9, which in 1994 struck Jupiter with the violence of several, full-scale nuclear wars.(47) This is certainly a great collection of essays, but it is not, as the book promises, a seamless (完美的，无逢隙的)synthesis of our current knowledge.

Nobody can fault the range of articles Levy has i.ncluded. There are essays on the planets, moons and assorted debris (碎片)in the Solar System, and on our Galaxy, the Milky Way.(48)

The contributors, too, are stars in their own fields. Not many books can boast chapters written by such giants as Erwin Schrodinger and Francis Crick. My personal favourites are a piercingly clear essay by Albert Einstein on general relativity and an article by Alan Guth and Paul Steinhardt on the inflationary (膨胀的)Universe.

So much for the book&39;s content. But Levy has not succeeded in providing an accurate synthesis of our current knowledge of the cosmos, which the book Jacket promises. Gathering together previously published articles inevitably leaves subject gaps, missing explanations and so on.(49) But there isn&39;t one. In fact, surprisingly for a book so densely packed with information, there is no index.

Collecting essays in this way is clearly a good publishing wheeze (巧妙的生意). But this approach shortchanges the public, who would be better served by an account moulded into a seamless whole.(50) However, for the next edition, please, please can we have an index？

A. Tegmark fears he may hold the record for the longest time taken to read one book.

B. In a more positive vein, this is a wonderful collection of essays to dip in and out of if you already have a good overview (概述)of current cosmic understanding.

C. Levy is an active astronomer and an accomplished writer, so you&39;d expect him to provide a broad and accurate picture of our current understanding of the cosmos.

D. Scientific American has attempted to cater to this need by bringing together essays that have appeared in the magazine.

E. To some extent, these could have been plugged with a glossary (词表)of terms.

F. Also included are contributions on the world of subatomic particles, the origin of life on Earth and the possibility of its existence elsewhere.
