“In school you learn that it is the thumb that separates human beings from the lower primates. The thumb is an evolutionary triumph. Because of his thumbs, man can use tools; because he can use tools he can extend his senses, control his environment and increase in sophistication and power. The thumb is the cornerstone of civilization!”

“Performance enhancements are most impressive when used by that sedentary athlete, the videogamer. After he turns to hitchhiking in disgrace, his giant thumbs can take him anywhere.”

“It's only his thumb brushing slowly across the lower edge of my lip, but it's as if time slows and the sweep of that thumb below my mouth takes forever. It is no spell that I know of, but it holds such magic, I can scarcely breath. He pulls his hand away fast, aware of what he's done. But his touch lingers.”

“...the magic was a tool, though a natural, mysterious tool. In its awareness of the magic, his human nature had desired to connect with it, to use it. The whisperings were the voice of his own awakening, not the seductive call of a dark power. Using it was not corruption, but a natural extension of his being. And he could control the manner in which he used it. He would.”

“I'm sure, you'll never again have a problem with a tool or a machine. No more hammered thumbs, no vacuum-cleaner catastrophes." "That'll take a second miracle." "Because all that clumsiness was never anything but an elaborate excuse not to have a gun, not to learn how to use one.”

“He clearly wasn’t dissuaded, and stroked my jawline with his thumb. “You can run. You can keep running to the ends of the earth. But I won’t be far behind you.”
