Comments by Michael Griffin on why space exploration is important, and why we are doing a bad job explaining it.:

"I've reached the point where I am completely convinced that if NASA were to disappear tomorrow, if the American space program were to disappear tomorrow, if we never put up another Hubble, never put another human being in space, people would be profoundly distraught. Americans would feel less than themselves. They would feel that our best days are behind us. They would feel that we have lost something, something that matters. And yet they would not know why.

Real Reasons are intuitive and compelling to all of us, but they're not immediately logical. They're exactly the opposite of Acceptable Reasons, which are eminently logical but neither intuitive nor emotionally compelling. The Real Reasons we do things like exploring space involve competitiveness, curiosity and monument building.
***
When you do things for Real Reasons instead of Acceptable Reasons, you have a chance to obtain Real Success. And so we have a conundrum. The cultural ethos in America today requires us to have Acceptable Reasons for what we do. We must have reasons that pass analytical muster, that offer a favorable cost/benefit ratio that can be logically defended. We tend to dismiss out of hand reasons that are emotional, or are value-driven in ways that we can't capture on a spreadsheet. But, Acceptable Reasons alone don't take us where we really want to go.

In my view, the space business more than most other endeavors suffers from the fact that the most important, the best, and the most basic reasons for doing it are Real Reasons and not Acceptable Reasons. The Acceptable Reasons – economic benefit, scientific discovery, national security – are, in fact, completely correct. But they comprise a derived rationale, and are not the truly compelling reasons. And again, who talks like that, about anything that really matters to them?

It is my contention that the products of our space program are today's cathedrals. The space program addresses the Real Reasons why humans do things. It satisfies the desire to compete, but in a safe and productive manner, rather than in a harmful manner. It speaks abundantly to our sense of human curiosity, of wonder and awe at the unknown. Who doesn't look at a picture of the Crab Nebula, synthesized from visible-light Hubble photographs and Chandra x-ray images, and say "Oh my God?" Who can look at that and not experience a sense of wonder?"

The Bush proposal opens a debate for 2008.:
"The U.S. has long needed a debate over health care and tax subsidies, and President Bush got ready to rumble last night with his proposal to make insurance more affordable for most Americans.

For all the griping about our system, Americans have the most advanced health care in the world in part because we still have something resembling a private market for insurance. But it is not a truly efficient market because current tax policy lets businesses--but not individuals--deduct the cost of health expenditures. Thus most Americans with private insurance get it from their employers, which leads to inequities and insulates individuals from the real cost of their treatment decisions."

Sense of humor key to his approach:
"New Idaho Congressman Bill Sali proposed a bill Wednesday to combat obesity by reducing the Earth's gravity, saying that's no more unreasonable than the Democrats' legislation to increase the federal minimum wage.

Both defy 'natural laws,' he said.

'The well-intentioned desire to help the poor apparently will not be restrained by the rules and principles of the free market that otherwise do restrain American businesses and workers,' Sali told the House of Representatives. 'Apparently, Congress can change the rules that would otherwise affect the affairs of mankind.'"

Those with superior intelligence need to learn to be wise.:
"We live in an age when it is unfashionable to talk about the special responsibility of being gifted, because to do so acknowledges inequality of ability, which is elitist, and inequality of responsibilities, which is also elitist. And so children who know they are smarter than the other kids tend, in a most human reaction, to think of themselves as superior to them. Because giftedness is not to be talked about, no one tells high-IQ children explicitly, forcefully and repeatedly that their intellectual talent is a gift. That they are not superior human beings, but lucky ones. That the gift brings with it obligations to be worthy of it. That among those obligations, the most important and most difficult is to aim not just at academic accomplishment, but at wisdom."

Too many Americans are going to college.:
"In engineering and most of the natural sciences, the demarcation between high-school material and college-level material is brutally obvious. If you cannot handle the math, you cannot pass the courses. In the humanities and social sciences, the demarcation is fuzzier. It is possible for someone with an IQ of 100 to sit in the lectures of Economics 1, read the textbook, and write answers in an examination book. But students who cannot follow complex arguments accurately are not really learning economics. They are taking away a mishmash of half-understood information and outright misunderstandings that probably leave them under the illusion that they know something they do not. (A depressing research literature documents one's inability to recognize one's own incompetence.) Traditionally and properly understood, a four-year college education teaches advanced analytic skills and information at a level that exceeds the intellectual capacity of most people."

Half of all children are below average, and teachers can do only so much for them.:
"Today's simple truth: Half of all children are below average in intelligence. We do not live in Lake Wobegon.

Our ability to improve the academic accomplishment of students in the lower half of the distribution of intelligence is severely limited. It is a matter of ceilings."
