Now, let us hear another story. A man goes to India, consults a sage in a cave and asks him the meaning of life. In three sentences the sage tells him, the man thanks him and leaves. There are several variants of this story also: In the first, the man lives meaningfully ever after; in the second he makes the sentences public so that everyone then knows the meaning of life; in the third, he sets the sentences to rock music, making his fortune and enabling everyone to whistle the meaning of life; and in the fourth variant, his plane crashes as he is flying off from his meeting with the sage. In the fifth version, the person listening to me tell this story eagerly asks what sentences the sage spoke.
And in the sixth version, I tell him.
