"To my mind, the expression of divinity is in variety, and the more variable the creation, the more variable the creatures that surround us, botanical and zoological, the more chance we have to learn and to see into life itself, nature itself. If we were just human beings, living in a spaceship, with an algae farm to give us food, we would not be moved to learn nearly as many things as we are moved by living on a world, surrounded by all kinds of variety. And when I see that variety being first decimated, and then halved — and I imagine in another hundred years it may be down by 90% and there'll be only 10% of what we had when I was a child — that makes me very sad, and very despairing, because we need variety. We came from that, we were born from that, it's our world, the world in which we became what we have become."

“Military men! Damn it, they always thought in terms of hardware, black or white, our side or the other side. It was damned hard to get them to see gray at all, and getting them to tell dark gray from medium gray was impossible!”

“Don’t you find that predators are those who most often assert absolute rights to personal freedoms?”

“Myra subsided into outraged and sulky silence. Her romantic dream of motherhood had been riven into sharp-edged fragments by late-night feedings, constant diaper washing, and a baby who persisted in looking and acting like a baby, not like a young hero.”

“He thinks he’s a liberal, he’s generally on our side, but he’s also ex-military, and he falls for the national security gambit every time someone plays it. Star Wars. Stealth anything. Talk about burning the flag and he gets all choked up. Funny, so many of these guys think the country stands for the flag instead of the other way around. So long as Old Glory’s whipping in the breeze, it’s okay to deal guns to kids and cheat on your taxes.”

“The use of destructive, noisy machinery for recreational purposes must become anathema to humans, as unthinkable as eating one’s young.”

“Call me either Colonel or Doctor. Hearing both titles gives me a split personality, the two philosophies differing so widely. It is medicine’s philosophy that lives should be saved, of all sorts. It is our military’s philosophy that as long as a few cells are kept alive, actual lives may be dispensed with. A few inches of gut in a bottle is not, to my mind, a life, no matter what theological contortions one puts oneself through.”
