You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe

In exchange for freedom of inquiry, scientists are obliged to explain their work.

Organic as a dandelion seed, [the ship of our imagination] will carry us to worlds of dreams and worlds of facts

We seem, these days, much more willing to recognize the perils before us than we were even a decade ago. The newly recognized dangers threaten all of us, equally. No one can say how it will turn out down here. But this is also, we may note, the first time that a species has become able to journey to the planets and the stars. Sailors on a becalmed sea, we sense a stirring of the breeze.

Is it fair to be suspicious of an entire profession because of a few bad apples? There are at least two important differences, it seems to me. First, no one doubts that science actually works, whatever mistaken and fraudulent claim may from time to time be offered. But whether there are any miraculous cures from faith-healing, beyond the body's own ability to cure itself, is very much at issue. Secondly, the expose' of fraud and error in science is made almost exclusively by science. But the exposure of fraud and error in faith-healing is almost never done by other faith-healers.

Imagination will often carry us to worlds that never were. But without it we go nowhere.

The visions we offer our children shape the future.
