“One's not half of two; two are halves of one.”

“Linda and I aren't one and one. We are two halves that make a whole -- two halves fitted together are more efficient than either half would ever be alone!”

“And I saw then and there you take a man half-bad and a women half-bad and put their two good halves together and you got one human all good to share between.”

“It's true that the two halves were no longer hinged. They weren't clinging to each other, but each was a cream-colored wing with a rosy flush inside. I held one half in each hand. If I took this shell across the room or across the universe, and the other one stayed here, they'd still be two halves of a whole, and anyone would know they belonged together.”

“Two infinities: the one that stretches to the beginning but never touches-when you halve and halve and halve, infinitely-and then the one that spreads out into the endless, endless future, the endless, endless, distance.The set of infinities that is itself infinite.”

“There have been hermaphrodites around forever, Cal. Forever. Plato said that the original human being was a hermaphrodite. Did you know that? The original person was two halves, one male, one female. Then these got separated. That's why everybody's always searching for their other half. Except for us. We've got both halves already.”
