political will is a renewable resource - Al Gore

"The present threat is not based on conflicting ideas about America's basic principles. It is based on several serious problems that stem from the dramatic and fundamental change in the way we communicate among ourselves. Our challenge now is to understand that change and see those problems for what they are.

Consider the rules by which our present public forum now operates and how different they are from the norms our Founders knew during the age of print. Today's massive flows of information are largely only in one direction. The world of television makes it virtually impossible for individuals to take part in what passes for a national conversation.

Individuals receive, but they cannot send. They absorb, but they cannot share. They hear, but they do not speak. They see constant motion, but they do not move themselves. The "well-informed citizenry" is in danger of becoming the "well-amused audience".

Ironically, television programming is actually more accessible to more people than any source of information has ever been in all of history. But here is the crucial distinction: It is accessible in only one direction. There is no true interactivity, and certainly no conversation. Television stations and networks are almost completely inaccessible to individual citizens and almost always uninterested in ideas contributed by citizens.

So, unlike the marketplace of ideas that emerged in the wake of the printing press, there is much less of an exchange of ideas in television's domain because of the imposing barriers to entry that exclude contributions from most citizens."

The interior of the earth is extremely hot - several million degrees.

In the 1950s, John Kenneth Galbraith first described the way in which advertising altered the classical relationship by which supply and demand are balanced over time by the invisible hand of the marketplace. Modern advertising campaigns, he pointed out, were beginning to create high levels of demand for products that consumers never knew they wanted, much less needed. The same phenomenon Galbraith noticed in the commercial marketplace is now the dominant fact of life in what used to be America’s marketplace for ideas. The inherent value or validity of political propositions put forward by candidates for office is now largely irrelevant compared with the image-based advertising campaigns they use to shape the perceptions of voters. And the high cost of these commercials has radically increased the role of money in American politics — and the influence of those who contribute it.
