“If the mattress stains were anything to go by, a previous user had not so much suffered from incontinence as rejoiced in it.”

“I turned to my own bunk and examined it with a kind of appalled fascination. If the mattress stains were anything to go by, a previous user had not so much suffered from incontinence as rejoiced in it. He had evidently included the pillow in his celebrations.”

“These Cro-Magnon people were identical to us: they had the same physique, the same brain, the same looks. And, unlike all previous hominids who roamed the earth, they could choke on food. That may seem a trifling point, but the slight evolutionary change that pushed man's larynx deeper into his throat, and thus made choking a possibility, also brought with it the possibility of sophisticated, well articulated speech. Other mammals have no contact between their air passages and oesophagi. They can breathe and swallow at the same time, and there is no possibility of food going down the wrong way. But with Homo sapiens food and drink must pass over the larynx on the way to the gullet and thus there is a constant risk that some will be inadvertently inhaled. In modern humans, the lowered larynx isn't in position from birth. It descends sometime between the ages of three and five months - curiously, the precise period when babies are likely to suffer from Sudden Infant Death Syndrome. At all events, the descended larynx explains why you can speak and your dog cannot.”

“From that original colony sprang seven names that still feature on the landscape: Roanoke (which has the distinction of being the first Indian word borrowed by English settlers), Cape Fear, Cape Hatteras, the Chowan and Neuse Rivers, Chesapeake, and Virginia. (Previously, Virginia had been called Windgancon, meaning "what gay clothes you wear" - apparently what the locals had replied when an early reconnoitering party had asked the place's name.)”

“To tell you the truth, I'm amazed we've come this far," he said, and I agreed. We had hiked 500 miles, a million and a quarter steps, since setting off from Amicalola. We had grounds to be proud. We were real hikers now. We had shit in the woods and slept with bears. We had become, we would forever be, mountain men.”

“[About Uluru] I'm suggesting nothing here, but I will say that if you were an intergalactic traveler who had broken down in our solar system, the obvious directions to rescuers would be: "Go to the third planet and fly around till you see the big red rock. You can't miss it." If ever on earth they dig up a 150,000-year-old rocket ship from the galaxy Zog, this is where it will be. I'm not saying I expect it to happen; not saying that at all. I'm just observing that if I were looking for an ancient starship this is where I would start digging.”

“It is easy to overlook this thought that life just is. As humans we are inclined to feel that life must have a point. We have plans and aspirations and desires. We want to take constant advantage of all the intoxicating existence we've been endowed with. But what's life to a lichen? Yet its impulse to exist, to be, is every bit as strong as ours—arguably even stronger. If I were told that I had to spend decades being a furry growth on a rock in the woods, I believe I would lose the will to go on. Lichens don't. Like virtually all living things, they will suffer any hardship, endure any insult, for a moment's additional existence. Life, in short, just wants to be.”
