While science and technology play critical roles in sustaining modern civilization, they are not part of our culture in the sense that they are not c… - Henry Way Kendall

Distortion and false statements have a sturdy history in public discourse. Neither the government nor large organizations can be depended on to support their objectives honestly and with integrity. Replying in kind turns out not to be an option, not just to retain scientific integrity but for practical reasons. Critics, whether individuals or public interest groups, cannot afford to slant the truth, ever. Scientists are far more vulnerable to the consequences of their own ill-considered words than are laypeople, owing to the care and integrity that is believed to characterize the scientific approach to problems. Intentional distortions are almost always uncovered and the purveyors pilloried without mercy. It may not be forgotten for years and surfaces over and over again. So too will honest mistakes which, along with even minor exaggerations, are seized on and exploited mercilessly. Not a bad rule — one that I and some colleagues observe — is to pull back a bit in most argument. Not only should one never distort nor exaggerate, it is best, I believe, to understate.

The world's problems are pressing in on us all. The scale and impact of human activities now affects a great portion of the global resources important to human welfare. These activities are putting growing, often destructive pressure on the global environment, pressure that appears likely to increase as human numbers swell toward the doubling of the world's population that evidently lies ahead. These pressures can spawn or aggravate conflict that. in a world with so much destructive weaponry, generates important national security problems. Great changes are necessary to help ensure a humane future for the generations to come. Most of the world's scientific community and many people in the environmental movement are aware of the gravity of the problems. Yet despite sober warnings from these and other groups, in both the industrial and the developing world, re- medial efforts frequently appear powerless and ineffectual. The scientific community has not taken a sustained, powerful role in the public arena where this great cluster of issues is debated and where the problems must be resolved. There is much more that our community can contribute to assessment, warning, and proposals for new patterns of behavior.

What should thoughtful people do? Are there means to brighten future prospects in the face of such human myopia and stubbornness? There are many in the scientific community whose views are bleak. One biologist, speaking to me many years ago, remarked that many of his colleagues thought of the behavior of the human race as similar to a one-celled animal's. Such an animal may extend a pseudopod in search of food; if hurt or blocked, it pulls back, but otherwise its activity continues, mindlessly, without understanding, without end. With larger perils unperceived, it can destroy itself.
