“But Xeno came up with four paradoxes, I believe,” said Lady LeJean. “They involved the idea that there is such a thing as the smallest possible unit of time. And it must exist, mustn’t it? Consider the present. It must have a length, because one end of it is connected to the past and the other is connected to the future, and if it didn’t have a length then the present couldn’t exist at all. There would be no time for it to be the present in.” Jeremy was suddenly in love. He hadn’t felt like this since he’d taken the back off the nursery clock when he was fourteen months old.
