Charles looked at the woman again and decided Charles smiled wanly and got up. He stood by the bed looking at her. longer. But not now. Not now." He turned away and walked to the window. "Now the world is dead. The whole world is dead." New York lay quietly below him. It was the hour of indecision when day has not quite made up its mind to leave and night has not yet It had been very pleasant that afternoon. She had given of herself freely, warmly, and Charles had accepted. But then he had known that she would. It was not him, it was the circumstances. Under the protest. To any man, WHO HAPPENED TO BE THE LAST MAN ON EARTH! Charles picked up a heavy book end off the table and crashed it through flesh. Charles ignored it. Even smells had lost their customary stomach clenched up like an angry fist. "But I don't want to be the last man alive!" he shouted. "I don't know what to do! I don't know where to go, how to act! I just don't know—" window for several minutes. " Maybe I'm not the last! " The thought struck him with suddenness, promisingly, edged with swelling comfort to fill his emptiness. Charles got up slowly, noticing for the first time that his fingers He had to know—he had to find out. and dangled from the edge of the bed like a crazy pendulum. Charles conventionality. After all, it didn't make any difference now. was a mess of desolate carnage. Charles overlooked it. Shop fronts "That was it," he said to himself. "Pride. We called this the 'Proud Era.'

"But I've got to try." He In all of his life, Charles had never once glanced at The Index. Reaching the gigantic building, Charles pushed aside the body of a But he still remembered it and he still recalled the powerful emotional mechanical wonder had remained with him the rest of his life. "So different now," he thought, surveying the room. "Now it's empty, so of the world. The silence became unbearable. Charles walked to the master control panel. With newly acquired immediately above it would give the numerical strength of the area Charles activated the switches that would flash a schematic map of New not because she liked him, but because.... Charles stopped talking and forced his eyes upwards. Peripheral vision continued to move, slowly, reluctantly. They caught the over-all relief dot at the very heart of the map—and he understood. Charles was by himself, the last person alive in all of New York City. He stopped. For even as he spoke, the light winked out! The counter Why? the so-called "basic" drives: hunger, thirst, sex, shelter, warmth, companionship, elimination. Certainly more decisive in the history of the race. Man began to think, to differentiate himself from the other But thinking about "why" didn't answer the question itself, Charles free of bodies. "You've got about ten minutes warning," he said to himself. "I guess that most people wanted to die inside of something—inside of anything. The silence was like a weight hanging around his neck. Not an insect the most perfect? Had he led the best of all possible lives? Was that it? Had God, in His infinite wisdom and mercy, spared his life, saved Charles sighed. Chance. That was it! The laws of probability, the bell-shaped curve, throw the dice toss the coin. assumptions about good and evil, no need for teleological arguments concerning cause and effect. Simply explain it by chance. Somebody had to be the last to go and that was— "No," Charles said, standing up in the quiet of the spring evening. "No, chance won't do it. No man can reckon with chance. The mind Charles stopped walking suddenly. No cave, he thought. No place to sleep out the long one, no place to rest while time came to change things around and make them for the better. No place to hide. And suddenly it was the most important thing in life to him to find his was. He let the coffin down slowly into the depression, then piled up "I can't very well bury myself," he said. "I guess it will rain after "It ought to be something impressive," he thought out loud. "Something Make it simple, he thought. And he finally wrote: HERE LIES THE BODY OF THE LAST MAN ON EARTH Yes.

He got up and started for one of the restaurants near the park. Later on, when there was more time, he'd find a piece Somehow, though, since things were ready and it didn't make too much difference, it seemed to Charles that he'd probably have a long time He smiled. Strange, but now he wanted very much to go on living, alone or not. There were things he could do, ways to keep occupied. He wouldn't mind it so much. But he wanted more and more desperately with each passing second to retain his foothold on the tenuous path of The tantalizing thought of "why" puzzled its way back into his mind. conclusion that he would live for a long time. Later, in a few days perhaps, he would think about it. In a little while he'd have plenty of now he thought he almost had the answer, if there were an answer. He part of his mind clamped down, obscuring the thought, rejecting the quickly repressed the idea. It couldn't be the plague. He was immune! tearing down the defenses of his mind, putting an end of his thoughts He wanted to protest, but there was no one to listen to him.

The answer to it all poked its face out from the recesses of his mind and sapped the last bit of his energy, corroding his nerves and dying muscles. Now he knew, and the knowing was the end of it. into it, swinging senseless in the air, pointing accusingly at the empty coffin. The world will end, not with a bang, nor with a whimper, but with the last man's anguished cry at the unreasonableness of it all. another of its kind. "It is finished?" asked the second. "Yes.
