“How would an immortal being have a passport? Quite simply, how? Dirk tried to imagine what might happen if—to pick a name quite at random—the God Thor, he of the Norwegian ancestry and the great hammer, were to arrive at the passport office and try to explain who he was and how come he had no birth certificate. There would be no shock, no horror, no loud exclamations of astonishment, just blank, bureaucratic impossibility. It wouldn’t be a matter of whether anybody believed him or not, it would simply be a question of producing a valid birth certificate. He could stand there wreaking miracles all day if he liked but at close of business, if he didn’t have a valid birth certificate, he would simply be asked to leave.”
