ワニのパラドックス
原文は次の通り。
A Crocodile had stolen a Baby off the banks of the Nile. The Mother implored him to restore her darling. "Well," said the Crocodile, "if you say truly what I shall do I will restore it: if not, I will devour it." "You will devour it!" cried the distracted Mother. "Now," said the wily Crocodile, "I cannot restore your Baby: for if I do, I shall make you speak falsely: and I warned you that, if you spoke falsely, I would devour it." "On the contrary," said the yet wilier Mother, "you cannot devour my Baby: for if you do, you will make me speak truly, and you promised me that, if I spoke truly, you would restore it!" (We assume, of course, that he was a Crocodile of his word; and that his sense of honour outweighed his love of babies.
