For instance, a fortune-teller may inform you, having pocketed your two guineas, that a rich uncle in Australia is going to leave you a million pounds next year. She doesn't promise you the million pounds herself; obviously that is coming to you anyhow, fortune-teller or no fortune-teller. There is no suggestion on her part that she is arranging your future for you. All that she promises to do for two guineas is to give you a little advance information. She tells you that you are coming into a million pounds next year, and if you believe it, I should say that it was well worth the money. You have a year's happiness (if that sort of thing makes you happy), a year in which to tell yourself in every trouble, "Never mind, there's a good time coming"; a year in which to make glorious plans for the future, to build castles in the air, or (if your taste is not for castles) country cottages and Mayfair flats. And all this for two guineas; it is amazingly cheap. And now consider what happens when the year is over. The fortune-teller has done her part; she has given you a year's happiness for two guineas. It is now your uncle's turn to step forward. He is going to give you twenty years' happiness by leaving you a million pounds. Probably he doesn't; he hasn't got a million pounds to leave; he has, in fact, just written to you to ask you to lend him a fiver. Well, surely it is the uncle who has let you down, not the fortune-teller. Curse him by all means, cut him out of your will, but don't blame the fortune-teller, who fulfilled her part of the contract. The only reason why you went to her was to get your happiness in advance. Well, you got it in advance; and seeing that it was the only happiness you got, her claim on your gratitude shines out the more clearly. You might decently send her another guinea. This is the case if you honestly believe your fortune-teller. Now let us suppose that you don't believe. It seems to me that in this case you are entitled to the return of your money.
