The repugnance to what must ensue almost immediately,....

“ The repugnance to what must ensue almost immediately, and the uncertainty, were dreadful, he said; but worst of all was the idea, 'What should I do if I were not to die now? What if I were to return to life again? What an eternity of days, and all mine! How I should grudge and count up every minute of it, so as to waste not a single instant!' He said that this thought weighed so upon him and became such a terrible burden upon his brain that he could not bear it, and wished they would shoot him quickly and have done with it."The prince paused and all waited, expecting him to go on again and finish the story."Is that all?" asked Aglaya."All? Yes," said the prince, emerging from a momentary reverie."And why did you tell us this?""Oh, I happened to recall it, that's all! It fitted into the conversation—""You probably wish to deduce, prince," said Alexandra, "that moments of time cannot be reckoned by money value, and that sometimes five minutes are worth priceless treasures. All this is very praiseworthy; but may I ask about this friend of yours, who told you the terrible experience of his life? He was reprieved, you say; in other words, they did restore to him that 'eternity of days.' What did he do with these riches of time? Did he keep careful account of his minutes?""Oh no, he didn't! I asked him myself. He said that he had not lived a bit as he had intended, and had wasted many, and many a minute.""Very well, then there's an experiment, and the thing is proved; one cannot live and count each moment; say what you like, but one cannot." "That is true," said the prince, "I have thought so myself. And yet, why shouldn't one do it?""You think, then, that you could live more wisely than other people?" said Aglaya."I have had that idea.""And you have it still?""Yes — I have it still," the prince replied. ”
