“Yes, the money could be better spent on Earth. But would it? Since when has money saved by government redlining been spent on education and cancer research? It is always squandered. Let's squander some on Mars. Let's go out and play.”

“The nobility of the human spirit grows harder for me to believe in. War, zealotry, greed, malls, narcissism. I see a backhanded nobility in excessive, impractical outlays of cash prompted by nothing loftier than a species joining hands and saying “I bet we can do this.” Yes, the money could be better spent on Earth. But would it? Since when has money saved by government red-lining been spent on education and cancer research? It is always squandered. Let’s squander some on Mars. Let’s go out and play.”

“I agree with Dr. Makris. Does that mean I would let someone blow up my dead foot to help save the feet of NATO land mine clearers? It does. And would I let someone shoot my dead face with a nonlethal projectile to help prevent accidental fatalities? I suppose I would. What wouldn't I let someone do to my remains? I can think of only one experiment I know of that, were I a cadaver, I wouldn't want anything to do with. This particular experiment wasn't done in the name of science or education or safer cars or better-protected soldiers. It was done in the name of religion.”

“The way I see it, being dead is not terribly far off from being on a cruise ship. Most of your time is spent lying on your back. The brain has shut down. The flesh begins to soften. Nothing much new happens, and nothing is expected of you.”

“Entomologists have a name for young flies, but it is an ugly name, an insult. Let's not use the word "maggot." Let's use a pretty word. Let's use "hacienda.”

“People can't anticipate how much they'll miss the natural world until they are deprived of it. I have read about submarine crewmen who haunt the sonar room, listening to whale songs and colonies of snapping shrimp. Submarine captains dispense 'periscope liberty'- a chance to gaze at clouds and birds and coastlines and remind themselves that the natural world still exists. I once met a man who told me that after landing in Christchurch, New Zealand, after a winter at the South Pole research station, he and his companions spent a couple days just wandering around staring in awe at flowers and trees. At one point, one of them spotted a woman pushing a stroller. 'A baby!' he shouted, and they all rushed across the street to see. The woman turned the stroller and ran.”

“All good research-whether for science or for a book-is a form of obsession.”
