It is not hard to imagine serious public dangers emerging out of instances in which political, military, scientific or religious leaders are unable t… - Carl Sagan

We have examined the universe in space and seen that we live on a mote of dust circling a humdrum star in the remotest corner of an obscure galaxy. And if we are a speck in the immensity of space, we also occupy an instant in the expanse of ages. We now know that our universe or at least its most recent incarnation - is some fifteen or twenty billion years old. This is the time since a remarkable explosive event called the Big Bang. At the beginning of this universe, there were no galaxies, stars or planets, no life or civilizations, merely a uniform, radiant fireball filling all of space. The passage from the Chaos of the Big Bang to the Cosmos that we are beginning to know is the most awesome transformation of matter and energy that we have been privileged to glimpse. And until we find more intelligent beings elsewhere, we are ourselves the most spectacular of all the transformations - the remote descendants of the Big Bang, dedicated to understanding and further transforming the Cosmos from which we spring

It is possible - given absolute control over the media and the police - to rewrite the memories of hundreds of millions of people, if you have a generation to accomplish it in. Almost always, this is done to improve the hold that the powerful have on power, or to serve the narcissism or megalomania or paranoia of national leaders. It throws a monkey wrench into the error-correcting machinery. It works to erase public memory of profound political mistakes, and thus to guarantee their eventual repetition.

In our time, with total fabrication of realistic stills, motion pictures, and videotapes technologically within reach, with television in every home, and with critical thinking in decline, restructuring societal memories even without much attention from the secret police seems possible. What I’m imagining here is not that each of us has a budget of memories implanted in special therapeutic sessions by state-appointed psychiatrists, but rather that small numbers of people will have so much control over news stories, history books, and deeply affecting images as to work major changes in collective attitudes.

Ady also warned of the danger that “the Nations [will] perish for lack of knowledge.” Avoidable human misery is more often caused not so much by stupidity as by ignorance, particularly our ignorance about ourselves. I worry that, especially as the Millennium edges nearer, pseudoscience and superstition will seem year by year more tempting, the siren song of unreason more sonorous and attractive. Where have we heard it before? Whenever our ethnic or national prejudices are aroused, in times of scarcity, during challenges to national self-esteem or nerve, when we agonize about our diminished cosmic place and purpose, or when fanaticism is bubbling up around us — then, habits of thought familiar from ages past reach for the controls.
