He would have said more, but he was here startled by a piteous noise of crying, and the three found themselves confronted by an old woman dripping with sea-water, and with an expression on her face of the utmost misery. They soon recognised her as one of the passengers on the ship. She told them how she had been floated ashore on a spar, and how she had been sustained by a little roast pig, that kindly begged her to eat it, having first lain in her bosom to restore her to warmth. She was now looking for her son. 'And if I cannot find him,' said the old woman, 'I shall never smile again. He has half broken my heart,' she went on, 'by his wicked ways. But if I thought he was dead--dead in the midst of his sins--it would be broken altogether; for in that case he must certainly be in hell.' 'Old woman,' said the Professor, very slowly and solemnly, 'be comforted. I announce to you that your son is alive.' 'Oh, bless you, sir, for that word!' cried the old woman. 'But where is he? Have you seen him? Are you sure that he is living?' 'I am sure of it,' said the Professor, 'because enlightened thought shows me that he cannot be anything else. It is true that I saw him sink for a third time in the sea, and that he was then snapped up by a shark. But he is as much alive as ever in his posthumous activities. He has made you wretched after him; and that is his future life. Become an exact thinker, and you will see that this is so. Old woman,' added the Professor solemnly, 'old woman, listen to me--_You and your son are in hell._' At this the old woman flew into a terrible rage. 'In hell, sir!' she exclaimed; 'me in hell!--a poor lone woman like me! How dare you!' And she sank back in a chair and fainted. 'Alas!' said the Professor, 'thus is misery again introduced into the world. A fourth part of Humanity is now miserable.' The curate answered promptly that if no restoratives were given her, she would probably die in a few minutes. 'And to let her die,' he said, 'is clearly our solemn duty. It will be for the greatest happiness of the greatest number.' 'No,' said the Professor; 'for our sense of pity would then be wounded, and the happiness of all of us would be marred by that.' 'Excuse me,' said the curate; 'but exact thought shows me that pity for others is but the imagining of their misfortune falling on ourselves. Now, we can none of us imagine ourselves exactly in the old woman's case; therefore it is quite impossible that we can pity her.' 'But,' said the Professor, 'such an act would violate our ideas of justice.' 'You are wrong again,' said the curate, 'for exact thought shows me that the love of justice is nothing but the fear of suffering injustice. If we were to kill strong men, we might naturally fear that strong men would kill us. But whatever we do to fainting old women, we cannot expect that fainting old women will do anything to us in return.'
