Steve,

This just in from Washington...

Subject: Science Advisor
Date: Thu, 21 Nov 2002

Dear John,

I appreciate your taking the time to recommend the appointment of Steven Pinker to be my next science advisor and I am pleased to hear of his interest in the position.

I am impressed with the resume of Dr. Pinker which you sent earlier. Could you please ask him to prepare a memo which answers the following question:

"What are the pressing scientific issues for the nation and the world, and what is your advice on how I can begin to deal with them?"

In addition to obvious issues that have dominated the headlines during my first two years in office, I would hope to hear about less obvious scientific issues as well.

I need the memo by the end of December.

Thank you for your help.

Sincerely,

GWB

I wish the above was really an email from President Bush. It is not. It's the set-up for this year's Edge Annual Question — 2003, and because this event receives wide attention from the scientific community and the global press, the responses it evokes just might have the same effect as a memo to the President....that is, if you stick to science and to those scientific areas where you have expertise.

I am asking members of the Edge community to take this project seriously as a public service, to work together to create a document that can be widely disseminated to begin a public discussion about the important scientific issues before us.

Address your memo to the President and very briefly add your credentials (as in the example below). I will post the responses as they come in. Please email your response to me on or before January 1, 2003 for publication the week of January 6th.

I look forward to hearing from you.

Best,

JB


Happy New Year!

Today's Visions of the Science of Tomorrow

At the end of every year, John Brockman, a literary agent and the publisher of Edge.org, a Web site devoted to science, poses a question to leading scientists, writers and futurists. In 2002, he asked respondents to imagine that they had been nominated as White House science adviser and that President Bush had sought their answer to "What are the pressing scientific issues for the nation and the world, and what is your advice on how I can begin to deal with them?" Here are excerpts of some of the responses.

Dear W: Scientists Offer
President Advice on Policy


DEAR READER,

Congratulations! President George W. Bush is considering asking you to serve as his science adviser. He asks that you write him a memo addressing, "What are the pressing scientific issues for the nation and the world, and what is your advice on how I can begin to deal with them?"

So begins this year's online question from Edge, an e-salon of leading scientists and members of the "Third Culture" (in answer to C.P. Snow's scientists vs. humanists)...

This year—with smallpox vaccination, bioterror, stem-cell research, climate change, energy policy and missile defense dominating news—the annual question eschews intellectual posturing and gets down to practicalities...

...You can improve your own science education at www.edge.org, where the Edge memos will be available January 6.

Biomedical research in the United States has a distinguished record of contributing to knowledge and to new medical treatments. In the same way, research with cells derived from cloned human embryos will offer unique opportunities to study many extremely unpleasant diseases, perhaps one day to have treatments for these diseases and also to produce safer medicines. This research cannot be carried out in any other way.

Ian Wilmut

Mr President,

Biomedical research in the United States has a distinguished record of contributing to knowledge and to new medical treatments. In the same way, research with cells derived from cloned human embryos will offer unique opportunities to study many extremely unpleasant diseases, perhaps one day to have treatments for these diseases and also to produce safer medicines. This research cannot be carried out in any other way.

The diseases include motor neurone disease, diabetes and genetic causes of sudden heart failure. Researchers could learn a great deal about these diseases if they could study in the laboratory the cells that are affected by the disease. Later they would assess the effects of drugs upon the malfunctioning cells. One day it may also be possible use cells from cloned embryos to treat unpleasant degenerative diseases by supplying replacement cells for those that have been damaged in diseases such as diabetes or heart failure.

Each year thousands of people in the USA are killed by taking medicines, even if the medicine was prescribed and used appropriately. This is because people differ in the way that they react to drugs. Pharmaceutical companies would be able to reduce this risk to us all and design drugs to be safer and more effective if they could study these differences in function of liver cells. At present the only source of such cells for research is the liver of casualties, if the organ is not suitable for transfer to a patient. Liver cells with these important differences in responses to drugs could be derived from cloned embryos and be used first to study these genetic differences and then to design better drugs and to establish the basis for personalised treatments.

There is no fully effective treatment for any of these conditions and in some cases none at all. We all know people affected by them and may fall victim ourselves, as we get older. In these circumstances, it would be a tragedy if concern over the unsubstantiated claims of the birth of a cloned child led to legislation that prohibited these important research projects.

By contrast there is every reason to encourage legislation to prohibit the production of children by cloning. Apart from the many ethical and social concerns the evidence from experiments with animals all points to the conclusion that the likely outcome of attempts to clone humans would include late abortions, the birth of dead children and of abnormal live children. As there is no way to avoid this tragic outcome it is important that legislation is enacted as soon as possible to prohibit such attempts.

I urge you to distinguish between these two uses of the cloning procedure, to allow the research that has the potential to be so beneficial, while prohibiting the misguided attempts to produce children.

With the genetic material in hand of organisms such as human, mouse, and fruit fly, researchers now have the opportunity to understand these complex creatures so that we may one day better treat disease, fully understand evolutionary biology, and thus understand the most fundamental aspects of life and how we as humans function.

J. Craig Venter

Dear President Bush:

At no time in our history is science more important in our society and thus to your administration than now. We have made exciting and promising advances in so many areas of scientific and medical research yet we still have so much to learn. This is especially true in the rapidly growing field of genomics.

In just the last 10 years we have gone from having the complete genetic map of just a few microbes to today having completed the sequencing of more than 100 organisms. With the genetic material in hand of organisms such as human, mouse, and fruit fly, researchers now have the opportunity to understand these complex creatures so that we may one day better treat disease, fully understand evolutionary biology, and thus understand the most fundamental aspects of life and how we as humans function.

The future is indeed bright but only if we have a science-literate administration to help translate this basic research into potential treatments. With these great advances also come tough ethical issues. But we must not become mired in these debates nor let fear and ignorance win out over progress for us all. While I cannot accept the offer to be science advisor I would like to outline a few ideas for your administration to consider.

There are three key areas that need immediate attention:

• 1) Revamping the health care system using genomics and other predictive tools to move toward a preventative medicine based system.

• 2) Stepping up our efforts in developing deterrents and defensive mechanisms to overcome the biological warfare threat to humans and agriculture.

• 3) Moving as rapidly as possible toward a hydrogen-based economy.

Our health care system is suffering from double digit inflation while the number of uninsured and underinsured continues to rise beyond any acceptable level for a civilized nation. We have now the potential to dramatically change the cost of health care by using the new predictive tools that will come from the genomics revolution. It is imperative that we make the commitment to go the less costly route of preventing and limiting the extent of disease rather than treating symptoms after they occur as we do now.

On this same preventative theme we can greatly diminish or effectively eliminate the threat of bioterrorism by using the modern tools of genomics to more quickly and accurately detect a suspect agent including genetically modified organisms; develop new effective vaccines without the risk profile associated with current small pox and anthrax vaccines; and develop new effective antivirals and antibiotics.

While your administration has made great progress in providing new funding for these efforts, more direct funding for the National Institute for Allergy and Infectious Disease (NIAID) at the NIH will move this field faster.

Despite much discussion on the topic of alternative energy solutions, the United States continues to rely almost exclusively on fossil fuels. According to the U.S. Department of Energy (DOE) approximately 80 percent of all human-caused carbon dioxide emissions currently come from fossil fuel combustion. The DOE also estimates that world carbon dioxide emissions are projected to rise from 6.1 billion metric tons carbon equivalent in 1999 to 7.9 billion metric tons per year in 2010 and to 9.9 billion metric tons in 2020.

This continued consumption of fossil fuels is ample evidence that there is a growing need to eliminate carbon dioxide output into the environment and capture back some of the carbon dioxide associated with global warming. Recent climate modeling from Scripps Institute of Oceanography suggests that if climate change is allowed to continue unabated a temperature increase of just two degrees will be enough to dramatically reduce annual snowfall and ultimately food production due to the drought that will develop in our most important agricultural states.

As a nation we must invest in finding new solutions for our energy needs. I believe that genomics could provide a viable avenue for alleviating some of the problems associated with carbon-based fuels.

I believe it is imperative that we push forward on all the fronts outlined above to insure energy independence, national security, and an improved environment, health and well-being for future generations.

Your father called himself "the education president," and you have promised new educational policies in which"no child is left behind."

Steven Pinker

Dear President Bush,

Your father called himself "the education president," and you have promised new educational policies in which "no child is left behind." These affirmations of the centrality of education in a modern democracy are admirable. As our economy comes to depend increasingly on technology, and as modern media present us with unprecedented choices – in our lifestyles, our workplaces, and our political commitments – a child who cannot master an ever-increasing body of skills and knowledge will be left farther and farther behind.

Unfortunately, the goals of the Presidents Bush are not being realized. Most debates about education in this country focus on issues of administration: vouchers, charter schools, class size, teachers’ unions, budgets, high-stakes testing. Fewer have focused on the actual process of education: how events in the classroom affect the minds of the pupils. This is an area in which science – in particular, the sciences of mind – can make crucial contributions.

Your immediate predecessor was enthusiastic about applying research on the brain to education and child development. But as exciting as the field of basic neuroscience is, I suspect it will provide few insights into the process of education. All learning must change the brain, but the changes at the level of brain cells are pretty much the same in all complex organisms -- including mice, which don’t learn to read, write, or add. It is the patterns of changes across billions of neurons that determine the distinctively human forms of learning that face us in the classroom, and to understand them we need to understand how intact human beings perceive, think, and act. These topics are the province of the sciences of mind, particularly cognitive science, psychology, cognitive neuroscience, behavioral genetics, and evolutionary psychology, must be brought to bear on education in a more systematic way than has happened so far.

First and foremost, we must apply a scientific mindset to the educational process. People outside of the educational establishment are often shocked to learn how little in instructional practice has been evaluated using the standard paraphernalia of social science–control groups, random assignment, data collection, statistics. Instead, classroom practice is set by fads, romantic theories, slick packages, and political crusades. We already know that some methods of teaching reading work better than others; we need more of these assessments, and faster implementations of what works into classroom settings.

Second, the sciences of mind can provide a sounder conception of human nature, which ultimately underlies all educational policy. What is the mind of a child inherently good at? What is it bad at? Without answers to such fundamental questions we will be groping at random or plunging headlong in wrong directions. An emerging view is that the human mind is impressively competent at problems that were recurring challenges to our evolutionary ancestors – seeing and moving, speaking and listening, reading emotions and intentions, making friends and influencing people. It is not so good at problems that are far simpler (as gauged by what we can program a computer to do, for example) but which are posed only by a modern way of life: reading and writing, doing mathematical calculations, understanding the world of science or the mechanics of a complex society. If so, this has obvious applications for education, both positive and negative. We should not make false analogies that assume that children can learn to write as easily as they learn to speak, that learning math can be as fun as learning to run and throw, or that children in groups will learn to do science as readily as they learn to exchange gossip. On the other hand we can try to co-opt the mental faculties that work well (such as understanding how objects fall and roll) and get children to apply them to problems for which they lack natural competence.

Third, we can use an understanding of the mind to set priorities in education at all levels. The goal of education should be to provide students with the cognitive tools that are most important for grasping the modern world and that are most unlike the cognitive tools they are born with. Observers from our best science writers to Jay Leno are frequently appalled by the innumeracy, factual ignorance, and scientific illiteracy of typical Americans. This has implications in countless areas of the public and private spheres – for example, when people fall victim to scam artists and irrational exuberance in their investments, when they squander their money and health on medical and nutritional flim-flam, and when they misunderstand the advantages and disadvantages of a market economy in their political decisions. The obvious cure for these fallacies is enhanced education in relatively new fields such as economics, biology, and probability and statistics. Unfortunately, most high-school and college curricula have barely changed since medieval times, and are barely changeable, because no one wants to be the philistine who seems to be saying that it is unimportant to learn a foreign language, or English literature, or trigonometry, or the classics. But no matter how valuable a subject may be, there are only twenty-four hours in a day, and a decision to teach one subject is also a decision not to teach another one. The question is not whether trigonometry is important, but whether it is more important than statistics; not whether an educated person should know the classics, but whether it is more important for an educated person to know the classics than to know elementary economics. In a world whose complexities are constantly challenging our intuitions, these tradeoffs cannot responsibly be avoided.

... my proposal is on a different front: to dramatically increase funding for promising new methodologies in the field of "human somatic cell engineering," which bypass entirely fetal stem cells. These emerging technologies create new tissues with a patient's own DNA by modifying one type of cell (such as a skin cell) directly into another (such as a pancreatic Islet cell or a heart cell) without the use of fetal stem cells.

Ray Kurzweil

FIRST, consider the following: would-be bioterrorists have no need to put their "inventions" through the FDA for approval. But the scientists we are depending on to develop the defensive technologies (for example, new anti-viral medications) are required to go through this extremely cumbersome process. Complying with these regulations not only takes many years, but slows down the entire innovation process.

If we look at an analogous offensive-defensive standoff, that of software viruses, we find that the cyberterrorists are indeed creating and unleashing ever more sophisticated software pathogens. But development of the defensive technologies (for example, antiviral software) has been able to keep pace, and software viruses are at worst a nuisance. We have done so well precisely because the development of software technologies is unhampered by sluggish regulatory procedures. We will need the same speed of innovation and implementation in the biological sciences.

In the current environment, when one person dies in gene therapy trials, there are congressional investigations and all gene therapy research comes to a grinding halt. There's a legitimate need to make biomedical research as safe as possible, but our balancing of risks is completely off. The millions of people who desperately need the advances to be made available by gene therapy and other breakthrough biotechnology advances appear to carry little political weight against a handful of well publicized casualties from the inevitable risks of progress.

This equation will become even more stark when we consider the emerging dangers of bioengineered pathogens. What is needed is a change in public attitude in terms of tolerance for needed risk. The leadership for creating this change can only come from the top official, the President of the United States.

SECOND, on another biotechnology front, pressure will heat up considerably this year in the controversial area of stem cell therapies. The number of available germ cell lines has turned out to be a small fraction of the 60 lines that were to be made available for research purposes. Although I would advocate that this policy be reconsidered, my proposal is on a different front: to dramatically increase funding for promising new methodologies in the field of "human somatic cell engineering," which bypass entirely fetal stem cells. These emerging technologies create new tissues with a patient's own DNA by modifying one type of cell (such as a skin cell) directly into another (such as a pancreatic Islet cell or a heart cell) without the use of fetal stem cells. There have been breakthroughs in this area in the past year. For example, scientists from the U.S. and Norway successfully converted human skill cells directly into immune system cells and nerve cells.

Consider the question: what is the difference between a skin cell and any other type of cell in the body? After all, they all have the same DNA. The differences are found in protein signaling factors that we are now beginning to understand. By manipulating these proteins, we can trick one type of cell into becoming another.

Perfecting this technology would not only diffuse a contentious ethical and political issue, it is also the ideal solution from a scientific perspective. If I need pancreatic Islet cells, or kidney tissues, or a whole new heart, to avoid autoimmune reactions, I would strongly prefer to obtain these with my own DNA, not the DNA from someone else's germ line cells. The feasibility of doing this has been demonstrated, and there should be a crash program to perfect a technology that could dramatically improve the health of all Americans.

THIRD, on a different front, that of energy, there has been dramatic recent scientific progress in developing hydrogen fuel cells, including microscopic-sized fuel cells using the same technology that fabricates electronic circuits. These fuel cells, based on micro-electronic mechanical systems (MEMS) can be scaled from tiny devices that will power everything from portable electronics up to cars, appliances, and homes. These systems use safe fuels such as methanol and generate no emissions other than tiny amounts of water and carbon dioxide. The fuels can be fabricated without environmental impact from widely available coal and shale oil with new technologies that capture emissions. All of the requisite technologies have been demonstrated.

Perfecting these new hydrogen-based energy sources would have profound and positive implications for the economy and the environment, not to mention the geopolitical minefields of our current fossil fuel-based economy.

New insights in developmental biology—our similarities to not only chimpanzees and baboons, but to fruit flies and worms, the genomic revolution and the invigorated emergence of neuroscience are all candidates for unforgettable discoveries. They must be pursued with all the means at our disposal. I would like to address a totally different one: the birth of our universe.

Gino Segre

Dear President Bush:

We are becoming increasingly aware of the connectedness and smallness of our world. Our problems are global- we are all affected by what one area or country does. Mid-western industrial pollution impacts on Washington D.C. air quality; Antarctic ice melting causes flooding in Bangladesh and Peruvian El Ninos can be traced to atmospheric pressure seesaws between the Pacific and the Indian Oceans. The AIDs epidemic's ravages know no boundaries. These realizations have changed the way we think and must change the way we act. Finding ways to deal with these issues and ones like them is a pressing scientific need as well as a political, economic and moral one.

Parallel to these concerns, however, are topics that are pressing even though they do not directly alter the quality of our everyday life. Science deals with day-to-day matters, but it also challenges us to leave the legacy of its discoveries to future generations. The Greeks are remembered because of their findings in philosophy and geometry, not because of territorial conquests. Copernicus' realization of the Sun's centrality marks the Renaissance. We want to be remembered in the centuries that come because of our own great achievements, ones that our descendants will say changed the way they see the world.

New insights in developmental biology—our similarities to not only chimpanzees and baboons, but to fruit flies and worms, the genomic revolution and the invigorated emergence of neuroscience are all candidates for unforgettable discoveries. They must be pursued with all the means at our disposal. I would like to address a totally different one: the birth of our universe.

A century ago there was no scientific theory of the universe's origin. It has been less than 40 years since we obtained the first evidence of radiation in the creation's aftermath and only a decade since we established convincingly that the universe was once a super-dense, ultra hot medium at essentially one common temperature. I said "essentially" because there are small deviations in that record; differences far less that a part per thousand from point to point in the sky, but these provide the clue to all the formations of galaxies, stars and planets that followed. This journey back in time is the greatest archaeological expedition ever undertaken, the uncovering of how our universe began and evolved. We almost have the tools in hand for embarkation on this voyage and should not dawdle.

Through the past century's insights, we have come to realize that we live on an ordinary planet circling a typical star of a mid-sized galaxy. Perhaps there is one additional step—that our very universe is not an anomaly in a continuum of space and time. We can leave a trace greater than Copernicus did. Such discoveries, achieved by scientists engaged in international collaborations and speaking the common language of science may serve as a role model for a world in which national, ethnic and religious barriers are broken down.

I believe it is a pressing issue for the nation and the world to have dreams worthy of the best it can achieve.

Sincerely yours,

Science does not allocate equal time or space to all ideas once the winnowing process of quality assessment has begun. To follow the political doctrine of "balance" diminishes democracy since it distorts the knowledge base upon which sound decisions should be made.

Stephen H. Schneider

We all share a strong belief in democracy. But it can only function well when the people understand the choices they need to make and are in a position to make trade-offs rationally. As issues get increasingly complex, ignorance decouples the people from the knowledge they need to help guide policy choices that can shape our future. Illiteracy in all forms—and especially in scientific matters—is a threat to a functioning democracy.

Woodrow Wilson said about a century ago "what are we if we have to be taken care of by a handful of experts who know the job, for if we don't know the job we are not truly free". Therefore, as Science Advisor I would work to greatly enhance the scientific literacy of the public—but not just the public, also government employees, elected officials and the media.

Science literacy is not just about the "facts"—knowledge of chemistry, physics, biology or economics per se. More important for non-specialists is to understand the process of science, and how science interacts with public policy issues and gets communicated via the media.

The media and political institutions are typically advocacy based—if a reporter gets the views of a Democrat, she must also get the views of a Republican. That is certainly appropriate in covering political stories, but rarely are complex issues of science simply decomposable into two polarized positions. Moreover, not only are there many possibilities, but relative probabilities are attached by scientific assessment to each of these possibilities.

Thus, an "equal time" doctrine is in fact a miscommunication of what science knows or how it works. Science is about quality, not equality. However, equality of opportunity to get your data and ideas heard is essential too, but via forums in which people who are knowledgeable about the complexities are present and in peer reviewed publications. Such institutions of science are where probabilities get thrashed out.

Science does not allocate equal time or space to all ideas once the winnowing process of quality assessment has begun. To follow the political doctrine of "balance" diminishes democracy since it distorts the knowledge base upon which sound decisions should be made. In science all views are not given equal time or credence because the scientific process of assessing likelihood takes precedence over mere inclusion. This leads to many conflicts over controversial policy issues, like climate change, strategic defense or health policy.

Climate change—in particular Global Warming—is a good case in point. No honest scientist can assert with total confidence it will turn out to be mild or catastrophic. But a dozen scientific assessments have shown that the "good for you" and "end of the world" scenarios are the two lowest probability outcomes. Some benefits are likely, but so too are a range of risks—especially for natural systems and in poorer countries.

The current political debates in which mild/catastrophic views are polarized and get the bulk of the attention in the media and in front of congress is an unfortunate distortion of what the scientific community has reported in its assessments. Such false dichotomy debates impede, rather than enhance democracy since they are not accurately representing what is known and at what likelihood.

The role of science the is clear: assess what can happen and what are the odds of it happening. The role of policy—driven by the beliefs of the public—is to make value judgments on how to react to the odds of various possibilities. It will take some major realignment of institutions like the media and congressional hearings apparatus to back away from the model of polarized advocates toward a doctrine of "perspective": reporting and debating based on the assessment of the likelihood of various events, not giving advocates of extreme opposite views equal time or space.

Over time, better applications of science by a public and officials who understand what can happen and at what odds will strengthen democracy and distance it from both the special interests that spin and distort to bolster ideological or client interests and the elitism of the few people who are the only ones who currently "know the job".

Your number one priority in science and technology should be a new commitment to international public health. It is not a particularly sexy topic; it needs no new nano-know-how, nor a radical change in our way of seeing the physical world. It will create no great technical advantage for America, nor add to its already impressive defenses. Though it will employ the talents of hundreds of thousands around the world, relatively few of them will be on the cutting edge of research. But it is what you must do, nonetheless.

Oliver Morton

Dear Mr President,

Your number one priority in science and technology should be a new commitment to international public health. It is not a particularly sexy topic; it needs no new nano-know-how, nor a radical change in our way of seeing the physical world. It will create no great technical advantage for America, nor add to its already impressive defenses. Though it will employ the talents of hundreds of thousands around the world, relatively few of them will be on the cutting edge of research. But it is what you must do, nonetheless.

I, like you, am a believer in progress. And it is for that reason that I expect our descendants in a century or two to look back on our age and hold us in contempt. Not for the fact that we fought wars; some wars need to be fought, and some wars are hard to stop. Nor for the fact that we polluted the environment; we are, after all, becoming aware of the problems we have been storing up, and we are beginning to address them on many levels. Our descendants will despise us for having been content to live in a world where millions of poor people died each year for want of basic medical interventions that the rich half of the planet took for granted. And they will be right to do so.

Half a million women die each year because of complications surrounding pregnancy and childbirth; 99% of those women are in low and middle income countries. Saving the vast majority of them requires nothing more than providing trained birth attendants. The 1.6 million children in poor countries who die every year from measles, tetanus and pertussis could almost all be saved by the provision of simple vaccines, and if vaccines were developed against some of the other diseases that kill poor children—diarrheal diseases and diseases of the respiratory tract—that number could be doubled.That's without starting on malaria, which kills over a million a year on its own. Vaccines against malaria would be a great boon, and should be a high priority—but even interventions available today, such as insecticide impregnated sleeping nets and drug treatment, could save hundreds of thousands. Aggressive extensions of existing tuberculosis treatment programs could save millions more each year .

Some of your other advisers will tell you that there is no quick fix for any of this—that the best medicine the poor of the world can get is economic development, which slowly raises health standards in its wake. They are wrong. It is possible to achieve impressive health gains in very poor countries if the will and the resources are there. There is good reason to believe that improving the health of the poor makes subsequent economic development faster and more certain—and helps plant the seeds of stable democracy.

This is not to say that the problems can be solved simply with money and supplies. New interventions will be needed—most sorely vaccines against AIDS and malaria. And much will need to be done to build the capacity of health care systems to serve the poor. But that is not an intractable problem—it has been solved in various ways in various places. Evidence of a real commitment among rich countries to providing the necessary resources would galvanise public health workers around the world to take up those solutions and invent new ones of their own. The idea that spending on aid is necessarily wasted is a cynical and self-serving lie. If you don't believe me, ask Bill Gates.

Other advisers will tell you that the American people will resent money spent overseas when many are uninsured at home. Feel free to tell them that you have some plans for dealing with that problem too. Feel free to tell them that there will also be many benefits to spending money on the health of the poor; that it will grow new markets and win new friends, improving America's image both among those who benefit from this new generosity and those in Europe and Japan suddenly obliged to match it. But tell them too that you are doing this not for those reasons, but because it is the right thing to do.

And tell them that the American people are not as small of heart or mean of spirit as they imagine. Tell them that the American people will understand that the annual $8 billion budget you intend to have set for this program by the end of your second term is less than one percent of what America spends on health care. Tell them that every American couple that leaves a maternity ward with a healthy baby will be happy to think some of their money is making sure a mother in Africa doesn't bleed out unattended. Tell them the opportunity to change the world does not come often—and that as such opportunities go, this one is cheap.

I wouldn't want you to cut other science and technology spending to this end. But if you were to decide that was the only way to balance the books, then I would say go right ahead. The end purpose of research is knowledge with which to improve the human lot. At the moment we already have the knowledge we need to save hundreds of millions of lives over the coming decades, and if push were to come to shove for a few years, using that knowledge should be a higher priority than storing up more knowledge for the future .

You and I, as believers in progress, have faith that the future will be able to take care of itself. We must turn our attention to the present.

I would urge you to set aside perhaps a billion dollars to fund new fellowships for graduate students from predominantly Islamic countries to come and study science (broadly construed) in the United States.

Rodney Brooks

Dear President Bush,

Science and the technology that flows from it have been great strengths of the United States; without them the US would not be the single superpower that it is today in the world.

For the last fifty years that science has been carried out largely in the open and has been shared with the rest of the world. That sharing has been a source of great strength. The US graduate education system is the strongest in the world and many international leaders have had some of their training in our Universities. The openness and the way in which our universities have been run as meritocracies, not places where national origin or religion is considered in evaluating one's work, has attracted waves of immigration of great scientists and engineers to this country.

There is a place for classified and restricted research but it is mostly in areas that are close to application, not in fundamental scientific and engineering questions. The place for that research is not at our universities. The great universities of the US should remain as open arenas for all areas of research where they act as an engine of creativity that feeds the scientific needs of the US and the world.

As science advisor I would urge you to continue, and strengthen, this policy of openness. I would urge you to set aside perhaps a billion dollars to fund new fellowships for graduate students from predominantly Islamic countries to come and study science (broadly construed) in the United States. I would urge you to direct the INS to treat foreign students as welcome guests rather than suspected criminals who must be monitored constantly by their host universities, and who are to be arrested, as has recently happened, when the courses they end up taking at a respected first rate university do not match some preconceived plan.

To reach out this generous hand to aspiring young students would be courageous in the current domestic climate of fear. But the long term payoff for the United States will be immense. It will create long term personal links between people in the countries we currently most fear and our own country. Based on past experience we can predict that many of those people will rise to positions of leadership and authority within their countries. In the shorter term it will be an act of generosity rather than aggression, and one can hope that it will have positive effects in the way the US is viewed. Besides that we will gain access to a large number of very smart, very driven, young minds who will help us and the world in making scientific progress.

Once I have convinced you to follow this advice I will get to work on some more radical ideas which involve funding science that is deep and curiosity driven, rather than dressed up as responding to politically justifiable immediate needs. Such science has been the well spring of the great advances throughout history.

Science is public knowledge. But science is not the only field where openness is important. The security failures of 9/11 were caused not by too little, but by too much secrecy. And the discussions that form public policy should be public...Science isn't poker: it only works when the cards are dealt face up. Don't go down in history as the Texan who closed the scientific frontier.

Seth Lloyd

Dear Mr. President,

Thank you for your invitation to advise you on matters of science. Science is after all the most public form of knowledge.

Scientific knowledge consists exactly of those pieces of information that can in principle be verified by anyone with the tools and desire to do so.

My advice to our highest elected official is to keep science public. Secret knowledge, no matter how laboriously acquired, is less than science.

Some knowledge, of course, must remain secret for the security of the nation. Do not have the National Security Administration publish its cryptographic keys.

But unless there is a clear security risk, publish all else. Why? Science belongs to the public: they pay for it; they benefit from it. The benefits of scientific knowledge accrue far more rapidly when that knowledge lies open for all to see, to test, and to try.

Your administration has presided over some good examples of the benefits of open dissemination of scientific knowledge. I will restrict my attention to my own field of quantum computation.

Quantum computers are devices that store information at the level of atoms, and that process that information in a way that respects the wave like nature of quantum mechanics. Quantum mechanics is famously weird, and one of the consequences of quantum weirdness is that even a small quantum computer, consisting of a few thousand atoms, would be able to break all existing public-key cryptosystems.

By their potential power, quantum computers pose a significant threat to the security not only of classified encoded material, but to the security of most commercial transactions, in particular those that take place electronically. Despite the clear application of quantum computation to problems of national security, your security agencies have elected to pursue the majority of their research on quantum computers by open competition for public funds, under the stipulation that the results of the research be published and made available to all.

This is a wise course. Although potentially highly disruptive, quantum computers are hard to build. Large-scale quantum computation is a decade away, at least. To construct such large-scale quantum computers will require the scientific and engineering community to solve wide-ranging problems of nanofabrication and control. The solutions to such problems will have wide application in the design and manufacture of high precision, high-power technologies across the board. The potential benefits of such research are a thousand times greater than any drawback from potential disruption to security.

By keeping the science public, your agencies are dramatically speeding the development not only of quantum computers, but of a wide variety of other quantum technologies, ranging from enhanced lithography to more accurate atomic clocks, to precise global positioning. The frontier of the very small offers huge space for development: keep this frontier open to all.

Science is public knowledge. But science is not the only field where openness is important. The security failures of 9/11 were caused not by too little, but by too much secrecy. And the discussions that form public policy should be public.

I know that other advisors are offering you conflicting advice: keep your cards close to your chest—don't let our enemies (or our allies) benefit from our hard-earned knowledge. Don't listen to them. Science isn't poker: it only works when the cards are dealt face up. Don't go down in history as the Texan who closed the scientific frontier.

Yours,

I hope your new Science Advisor comes to the job armed with knowledge of the rich history of junk science and false predictions served up to government in the last forty years.

Denis Dutton

Dear Mr. President,

Many thanks for your invitation to apply for the position of Science Advisor to the President. Alas, there is some mistake, for I am a philosophy professor. At their best, scientists respond to problems with answers, and this can be useful to presidents. Philosophers have a cranky habit of responding to answers with more problems. You don't need that.

Taking into account all of the poor scientific policy advice that has been promulgated in Washington for the last forty years, you'll need luck in your search for the right person. The record shows that scientists are as much victims of fashion as other ordinary mortals. Recall a few examples of science in predictive mode:

In the mid-1970, many climatologists warned of a coming Ice Age that would severely diminish agricultural productivity by year 2000.

• Frightened by dramatic allegations in the 1960s about the environmental effects of DDT, the U.S. banned the pesticide in 1972. In retrospect, the allegations of harm were so much hyperbole. In the meantime, millions of people, especially in Africa, have died of malaria, with Europe and the U.S. reluctant to support them in DDT mosquito eradication.

• Let's not forget the scientific predictions about oil and mineral resources. In the 1970s your predecessors in office were being told that there would be essentially no oil left by the 1990s. Gold would be $10,000 an ounce, of course.

• Overpopulation? When I was in the Peace Corps in India in the 1960s we all "knew," in line with expert scientific advice from the U.S. government, that the population explosion would cause massive, worldwide famine by the late 1980s.

This list could be expanded into periodic cancer scares, worries about the ozone hole, silicon breast implants, acid rain (another wildly exaggerated threat), air pollution, and so forth. It's odd when you think about it: though you and I might have enjoyed scary Frankenstein movies, when we were children, science and technology were seen as great forces for the benefit of mankind. Things shifted in the 1960s, and a spirit of pessimism began to invade science.

Today, it is much easier for scientists to receive grants if they indicate their research might uncover a serious threat or problem—economic, medical, ecological. Media fascination with bad news is partly to blame, along with the principled gloominess and nagging of organizations such as Greenpeace. But government itself has played its natural part. After all, as H.L. Mencken once remarked, "The whole aim of practical politics is to keep the populace alarmed, and hence clamorous to be led to safety, by menacing it with an endless series of hobgoblins, all of them imaginary."

Since I'm sure you're keen to avoid such alarmism, you'll need an advisor who can see through the fashions of science, and understand something of their psychology. The epidemiologist who slightly overstates the conclusiveness of his study suggesting that french fries might cause cancer (in mice) or the young climatologist on the global-warming gravy train are not basically dishonest people. You too might more easily buy into some doomsday scenario, if it meant regular business-class flights to major resorts to compare computer climate models with other experts (models that you know in your heart could not possibly predict average atmospheric temperatures fifty years hence, but what hell, the food's great).

I hope your new Science Advisor comes to the job armed with knowledge of the rich history of junk science and false predictions served up to government in the last forty years. The point is not to be cynical about fads and careerism, but wisely to choose where best to support both pure science and science that can give us beneficial technologies.

The resulting memo is practical and unimaginative. It may not be of much interest to the Edge community, but I think it would be more useful to the president than a wider-ranging document. The second memo is the unpractical and imaginative version. It is not very imaginative, because I still want it to be taken seriously as an agenda for the twenty-first century.

Freeman Dyson

Here two answers to the Edge Annual Question. In the first version I have followed your instruction to stick to science and to those scientific areas where I have expertise. The resulting memo is practical and unimaginative. It may not be of much interest to the Edge community, but I think it would be more useful to the president than a wider-ranging document. The second memo is the unpractical and imaginative version. It is not very imaginative, because I still want it to be taken seriously as an agenda for the twenty-first century.

Memo to the President (I)

The scientific enterprise in this country is generally in good shape and needs only modest increases in support to keep up with inflation. One weakness of the enterprise that needs to be addressed is the system of peer review that governs the support of investigator-initiated proposals. The peer-review system works well for proposals that lie within established disciplines of science. It works badly for proposals that lie outside or between established disciplines.

A glaring example of the failure of the system is the lack of support for large underground detectors of elementary particles. During the past year, the two most important discoveries in particle physics were made using such detectors, one in Canada and one in Japan. The United States has fallen behind in this highly promising area of research, because underground detectors lie between the disciplines of physics and astronomy. Physicist peer-reviewers failed to support underground detectors because they are not accelerators, and astronomer peer-reviewers failed to support them because they are not telescopes.

Similar failures of the peer-review system occur in areas of space technology that lie outside mainstream disciplines. They probably also occur in areas of biology and medicine with which I am not familiar. A possible remedy for this state of affairs would be to assign a small fraction of the national research budget, perhaps five or ten percent, to proposals that are exempt from the normal process of peer-review. The choice of exempt proposals to be supported could be made by directors of federal agencies, with the help of panels representing science as a whole rather than specialized disciplines.

Memo to the President (II)

During the last ten years, the human genome project has laid the foundation for a comprehensive understanding of human biology. The translation of the new understanding into cures for human diseases will be a slow and difficult process.

Meanwhile, a new century has begun. It is time for you to launch a bold new initiative in biology, a planetary genome project to sequence the genomes of all the millions of species that live together on this planet. This will require first of all an aggressive development of new sequencing technology, comparable to the development of computer technology during the last half century, so that the cost of sequencing will continue to fall as rapidly as the cost of computing.

The goal will be to complete the sequencing of the biosphere within less than half a century, at a cost comparable with the cost of the human genome. The successful completion of the project will bring an enormous increase in understanding of the ecology of the planet. Increased understanding could then be translated into practical measures to sustain and improve the ecology while allowing continued rapid economic development.

Detailed understanding of the ecology could lead to large-scale and cost effective use of solar energy and to stabilization of the atmosphere and the climate. Let this century be the century of cures for planetary as well as human diseases.

There are many excellent researchers who would make rapid progress in malarial "post-genomics" if substantial new money became available. It would therefore be widely recognised as a wonderfully enlightened action if you were to ensure that the National Institutes of Health introduced a malaria post-genomics programme, with a new budget of at least $300m, as a first step towards the prevention and cure of this devastating disease.

Philip Campbell

Dear Mr President

Your administration has commendably focused not only on the urgent ways in which science can help the nation, especially through the National Institutes of Health and the Department of Homeland Security, but also in boosting the broader and longer-term interests of the country by increasing the budgets of, for example, the National Science Foundation, whose science constituencies underpin critical sources of knowledge and skills. I am troubled by the half-hearted approach adopted by your administration towards alternative energy sources and climate research, but will leave those issues for another day.

However, every President should leave a personal legacy that goes beyond the national political and social goals of the moment. If that legacy addresses one of the major issues facing the wider world, so much the better.

Malaria provides you with precisely that opportunity. It affects hundreds of millions of people and kills well over one million every year. It affects countries across South America, Africa and South East Asia. The challenges are made all the more urgent by the development of multidrug resistance by the parasite.

There have been some positive moves from philanthropists and charities for the control of malaria and for the development of vaccines and drugs, and some limited progress with private-public partnerships. But these funds—two or three hundred million all told - are a drop in the ocean. Furthermore, they do not seriously address the longer term need to investigate the malaria parasite at a basic scientific level.

Some people will argue that we already have enough science, we simply need to develop better drugs, or a vaccine, or have better controls of the disease through prevention. History shows, however, that every one of these alternative routes has its own chronic difficulties. Addressing new opportunities in the basic science of the disease could, in the long term, deliver more far-reaching solutions.

The journal Nature recently published the sequence of the malaria parasite Plasmodium falciparum's genome, and other related fundamental information critical in understanding the parasite. That's a key step along the way, and provides a new platform on which to develop essential insights into the many biomolecular and cellular pathways by which the parasite survives and interacts with us, its indispensible hosts. New techniques are beginning to be applied, such as high-throughput analyses of the pattern of gene expression and of the interactions of proteins at key phases of the parasite's lifecycle. The new availability of the genome combined with these techniques will undoubtedly spur progress significantly—if there are funds to permit it.

For the United States to provide significant help in this battle would not simply represent an act of great good will. It would also be in the nation's long-term strategic interests. The less that so many developing countries have to battle with the illness and mortality of malaria and the social burdens that they bring, the more they can focus on economic and social development and provide new opportunities for US businesses and other organisations.

There are many excellent researchers who would make rapid progress in malarial "post-genomics" if substantial new money became available. It would therefore be widely recognised as a wonderfully enlightened action if you were to ensure that the National Institutes of Health introduced a malaria post-genomics programme, with a new budget of at least $300m, as a first step towards the prevention and cure of this devastating disease.

Science, like business, has been totally captured by the next quarter mentality, and it will require a deliberate effort to stress the long view so that our knowledge matches our predicament.

Kevin Kelly

Dear Mr. Bush,

Thank you for your confidence in me. Here are the three things you should encourage; these are neglected by our current science policy:

1) Develop Long Term Science.

Most science experiments, clinical studies, and data collection lasts about 4 years—the duration of a graduate student. Most problems we have before us last for generations. Science, like business, has been totally captured by the next quarter mentality, and it will require a deliberate effort to stress the long view so that our knowledge matches our predicament. Long-term studies can begin to alleviate much of our ignorance of climatic, environmental, health, social, and biological issues.

2) Foster a Global View.

While the United States is among the nations leading the world in monitoring and mapping its own territory, most of the world has not been mapped. We, as humans, lack a sufficient survey of the geology, habitat, weather, and biological diversity of our home planet. For instance we have identified as few as 5% of all the species living on earth. A detailed map of the planet, which would include geological assets, urban impacts, ecological assessments, and detailed cartographic information would be invaluable to business, military intelligence, social work, and peace and prosperity, at the very least, to the US. As it is we are trying to run a planet with only a dim sense of what it is.

3) Fund Blue Sky Work.

US universities were once renowned for funding work that could not possibly pay off for ten years or more. Much of university research was pure research that had no obvious application at all at the time of its funding. In an effort to weed out seemingly frivolous work that might wind up as a headline in a supermarket tabloid, a lot of bold research has simply been dropped. Research is now expected to show results quickly, and to fit into return on investment curves developed by business. This may be good for business, and maybe even for government in the short term, but it is disastrous for science, especially in the long term. Some federally funded research should aim for a ten- or even 25-year result horizon. This would create the strongest possible science culture.

These three things could be implemented without substantially increasing the science budget, although that is always a good idea.

The fear of smallpox as a weapon of mass destruction in the hands of terrorists is based either on the public information, which is speculative and anecdotal, or on military or secret intelligence sources which are unavailable.

Lawrence B. Brilliant, M.D.

Mr. President,

During the past several months, I've been frustrated by the smallpox puzzle and the accompanying national agony about vaccination. Dozens of people have cornered me asking "what should I do about vaccinating my family" or, more pointedly: "are you or your family getting vaccinated?"

I was vaccinated against smallpox hundreds of times in the smallpox program in India, and again by CDC last year during the "smallpox bio terrorism" sessions for first responders. In this regard, it is appropriate that as President, you were recently vaccinated. My children, wife, mother, brother and neighbors have not been recently vaccinated and I do not recommend it, at least not yet. Based on the risks and benefits of what we know today, I do not recommend anyone rush out to get vaccinated unless they will be a "first responder" or work in a hospital emergency room.

Why? My decision is based on trying to solve many simultaneous equations. The smallpox dilemma has no simple answers, and making the correct decision may, literally, be a matter of life and death.

The facts today: Smallpox as a disease does not exist. It has been eradicated. A very small amount of the virus which causes smallpox, Variola, has been held frozen in liquid nitrogen in two "legal and secure" facilities in Atlanta and Moscow, as agreed to by the 150+ member states of the World Health Organization. It is easy to "awaken" the demon of smallpox if it is removed from these freezers. Except for a very controversial and potentially destabilizing removal last year of some viral material by U.S. Army scientist Peter Jahrling who used those viruses to infect monkeys with smallpox with the thought of testing smallpox anti viral agents and improved vaccines all the other legal viral samples remain in place. The fear of smallpox as a weapon of mass destruction in the hands of terrorists is based either on the public information, which is speculative and anecdotal, or on military or secret intelligence sources which are unavailable. Vaccination of 280 million Americans could cause potentially fatal vaccine side-effects in tens of thousands and death in 500 to 1000. In order to justify so many vaccine side-effects, there must be real evidence of incremental risk of an epidemic caused by vaccine preventable smallpox. There are at least three gating items, all of which must be true before it is logical to begin vaccinations against a disease which does not exist:

• Gating item #1: Smallpox virus must exist outside of the two "legal and secure" repositories where, with the only known exception being the Jahrling experiments, it has resided securely for nearly three decades

• Gating item #2: That smallpox virus which is outside of the two "legal and secure" repositories must have reached the hands of terrorists or nation-states that would use smallpox in war

• Gating Item #3: That smallpox virus which is outside of the "legal and secure" repositories, in the hands of terrorists with an intent to use it, must not have been genetically altered so as to be impervious to the vaccine we currently have.

As is quite clear from credible journalistic sources, Gating Item #1 appears to have occurred-Russian scientists operating under a Gorbachev approved billion dollar 5-year plan manufactured as much as 100 tons of Variola virus annually at a then secret facility called, ironically, Vector, near Novosibirsk, Siberia in the Soviet Union during the 1980's. There may have been other programs that have remained secret, just as the CIA program "Bacchus" to build a miniature anthrax production lab stayed secret virtually until the anthrax attacks of 2001.

There is no public knowledge, and I stress "public" for obvious reasons, that Gating Item #2 is true. The major known sources of concern are:

• a) Saddam Hussein used saran gas and anthrax in missiles and shells and attempted to use Camelpox in horrid experiments against the Kurds. Logic dictates that if he does have smallpox, he is a serious threat to use it as a "doomsday" weapon.

• b) Weapons inspectors found a refrigerator in Iraq, "ominously" labeled "smallpox" during the last round of inspections-we do not know if the "smallpox" referred to the disease of smallpox or the vaccine against it, but there were active cases of smallpox in Iraq as late as 1972 and there is no reason to believe harvesting viral specimens from those cases was not done. Iran, Iraq's neighbor and sometime enemy, certainly hid cases of smallpox from WHO inspectors (I was one of these) as late as the Shah's ceremonial coronation in 1972-73. When Iran and Iraq went to war a few years later, Saddam Hussein had reciprocal regional reasons for hoarding the Variola virus.

• c) Al Qaeda documents, including some found on a personal computer purchased by a Wall Street Journal reporter, contained references to smallpox as a weapon to be used by terrorists. Taliban fighters and Al Qaeda terrorists frequented a Soviet era "weapons dump" just North of the Afghanistan border; it is not known if any biological weapons were included amongst the other weapons acquired there.

• d) Soviet smallpox epidemiologists, who had betrayed many of us in the World Health Organization by lifting smallpox scabs from patients in India and elsewhere, and then smuggling these infectious specimens back to Russia to become part of Vector's "collection" used to create the infamous India-1 "weaponized smallpox", fell on hard times after the breakup of the Soviet Union. So did some of the virologists at Vector who worked on weaponizing smallpox and other biologicals; there is evidence some of these scientists visited Iraq, and were paid to consult with colleagues in Saddam Hussein's government on biologicals. There has recently been an active US program to find other work for these scientists to rid them of the financial necessity of such activities. There is even the suggestion, strongly denied by her Russian colleagues, that the eminent smallpox virologist Dr. Nelja N. Maltseva, might have visited or even collaborated with the Iraqis.

As for Gating Item #3, no one knows. The well known Australian experiments altering a gene in mousepox suggests it would be easy for terrorists-or even college microbiology students who had access to pox to create a "superpox" impervious to today's vaccines. I won't go into the details but the bottom line is that if anyone had enough hatred and enough money, the creation of a vaccine-proof smallpox variant is well within the realm of the possible. Obviously, if the terrorists have vaccine-proof smallpox, it is silly to vaccinate anyone with a high risk vaccine that is impotent against genetically altered smallpox.

How great is the risk of adverse reactions? Again, no one can really quantify it because much has changed, for better and for worse, since the 1970's from which the last large datasets are available. At that time the death rate from vaccine was about 2 or 3 per million vaccinated, and the risk of serious side effects about ten times higher. There are factors today which might raise or lower the rate of complications. Thirty years ago far fewer Americans had immune systems compromised by chemo therapy or AIDs, and the prevalence rates of eczema, a serious contra indication to smallpox vaccine, were lower as well. On the other hand, recent data from Israel and from vaccination in the US military suggests that vaccinating young healthy pre-screened men and women carries very few risks of side effects and today's ICU medical care for vaccine complications is likely to markedly reduce fatalities. All in all, it is likely that ten to one hundred people per million vaccinated from the general public would have a very serious reaction or even death from the vaccine-somewhere between 3000 and 30,000.

And so, here we are, faced with the need to decide whether to vaccinate our families. We will each need to make personal decisions under conditions of uncertainty.

Here is why I chose not to vaccinate my family:

• 1) To the best of my knowledge, there is no proof of any link between the experiments at Vector and either Al Qaeda or Saddam Hussein, but concern is understandable. If any proof of linkage arises, I might change my mind.

• 2) If Saddam Hussein has smallpox, I believe he might well be crazy or desperate enough to use it as a "doomsday weapon" if he were about to be destroyed; but it is also likely that Iraqi scientists have the ability to genetically alter the virus to make it vaccine-proof. If it is an end game, why would he use a virus that we have a vaccine against? It makes no sense.

• 3) If Al-Qaeda has the smallpox virus, I do not believe they would be willing to use it. Unlike Saddam Hussein, Al-Qaeda seeks the victory of an entire people, a culture, a religion-not the hegemony of any individual. Smallpox is the ultimate boomerang weapon. If it is released from its captivity at Chicago O'Hare airport, it is only a matter of days before it infects Mecca and Medina. It is not a likely weapon for a war that is a "Clash of Civilizations" unless a combatant sought the destruction of both civilizations.

• 4) Smallpox can be prevented if an exposed person is vaccinated as late as four or five days after exposure. While there is some risk that smallpox could be spread unseen for the first attack, within two weeks cases would start to appear and for nearly all Americans, there would be ample time and ample vaccine to be vaccinated after the first attack and still be safe.

• 5) I do not want to go into the fear that a small minority of Americans have that the your administration is prone to exaggerate the risks of terrorism in general and smallpox in particular as part of an attempt to frighten the public into accepting the erosion of civil liberties. As horrible as that allegation is, I simply have no information on which to make any comment other than to note the fear exists. And for my purposes here, it really does not matter. Based on the evidence I have seen to date, the risk of getting a case of vaccine-preventable smallpox today is just not as high as the risk of an adverse reaction to the smallpox vaccine.

That is the conclusion that I have reached as of today. And unless or until that changes, I will not vaccinate my family and the ones that I love.

The point is, Mr. President, that a National Bureau for the Support of Science, with Cabinet status, is getting to be a necessity.

Mihalyi Csikszentmihalyi

Mr. President, allow me to start with a personal reminiscence. When I was being interviewed for my first teaching job, almost four decades ago, the head of the search committee ­ a nuclear physicist ­ told me in dismissive tones: "Well, now that we scientists have been able to harness the power of nuclear forces, let's see if you so-called social scientists can teach us how to use it." His tone of voice and smirk clearly meant that he didn't believe for a moment that we "soft" scientists were up to even such an easy task as that of preventing humanity from the misuse of nuclear energy.

Things haven't much improved since. To-day's issue of the Los Angeles Times (12/2/02), for instance, carries three stories on the front page that relate to the issue I am raising: One of them laments the fact that patients are increasingly refusing to participate in drug trials and medical experiments because they mistrust scientists; another warns about the leakage in the former Soviet arsenal of deadly weapons; and the third consists of a huge color photo of the black waves carrying spilled oil advancing on Spanish beaches.

Now you and I know that it is childish to blame such problems on science or on scientists. It is not their fault that their brilliant advances are so tragically misused, corrupted, trivialized. Yet I am afraid that the majority of our countrymen are going to draw that conclusion, with consequences that are too dire to contemplate. A re run of the Dark Ages would be much worse than the original.

Unfortunately our colleagues in the "hard" sciences have not been entirely helpful either. Their mantra has been: "Our task is to push further the boundaries of knowledge; what happens afterwards is not our responsibility; that's for society to decide." Fair enough: But let anyone else suggest how science should be used and he'll be crucified as a philistine. We all wish to have the proverbial cake and to eat it, too. Sooner or later, however, reality does intervene. It is perhaps time for this to happen to science.

The point is, Mr. President, that a National Bureau for the Support of Science, with Cabinet status, is getting to be a necessity. It should not be a body controlled by scientists. Just as war is too important to be left up to generals, and religion too important to be left in the hands of clergy, so is science too important to be given over to scientists. Nor should it be under the control ­ God forbid ­ of business interests or politicians. It is much easier to specify who should not control such a board than who should, but the task is too urgent for us to be deterred by such an obstacle. It should be a parliament composed by people who have demonstrated concern for the future of humanity: Scientists as well as laypeople ­ yes, even businesspersons, clergy, and generals.

The task of such a bureau would be to allocate a goodly proportion of the national revenue to projects that are important to our survival and wellbeing. Not to the discovery of more foul chemicals, deadly viruses, or laser guns circling around the planet. Instead, ways to produce clean energy, clean water, to keep biodiversity from disappearing should be supported. We should be preparing for the future, Mr. President, not continuing to invest in a mythical past. Currently science is at the service of speculators and mindless traffickers in destruction. It is time the rest of society reclaimed its rig
