“Outside, she thought that there ought to be a word for it: the air temperature that was perfectly neither hot nor cold. One degree lower, and she might have felt a faint misgiving about not having brought a jacket. One degree higher, and a skim of sweat might have glistened at her hairline. But at this precise degree, she required neither wrap nor breeze. Were there a word for such a temperature, there would have to be a corollary for the particular ecstasy of greeting it - the heedlessness, the needlessness, the suspended lack of urgency, as if time could stop, or should. Usually temperature was a battle; only at this exact fulcrum was it an active delight.”

“If your feet are in two buckets and the average temperature of the water is 90 degrees, you’re probably fine—unless one bucket is at 35 and the other is at 145 degrees. On average, you’re fine. Based on variation, though, you’re miserable.”

“Love, she thought, he'd typed "love" just as she had. A multifacedted word, love, there probably wasn't another word in this or any other language that had so many shades and degrees. She knew that he loved her and she loved him, just as she loved Adam and Adam loved her. But with love, theirs or his, it was always a question of degree, and what one was willing to do to express that degree.”

“I could speak by then, but neither of us thought it my best trick. Very often my exchanges with Ceno went something like:Sing me a song, Elefsis.The temperature in the kitchen is 21.5 degrees Celsius and the stock of rice is low. (Long pause.) Ee-eye-ee-eye-oh.”

“I guess the last remaining question is: What about the sombrero? It's still there, lying in the street but its temperature had returned to -24 degrees and fortunately for America it stayed there. Millions of tourists have walked all around it but not one of them has seen it, though it is in plain sight. How can you miss a very cold white sombrero lying in the Main Street of a town? In other words: There is more to life than meets the eye.”

“Diversity is a survival factor for the community itself. A community of a hundred million species can survive anything short of total global catastrophe. Within that hundred million will be thousands that could survive a global temperature drop of twenty degrees—which would be a lot more devastating than it sounds. Within that hundred million will be thousands that could survive a global temperature rise of twenty degrees. But a community of a hundred species or a thousand species has almost no survival value at all.”
