  5. [1] If each man had a definite set of rules of conduct by which he regulated his life he would be no better than a machine. But there are no such rules, so men cannot be machines.

  6. [2] I can’t have anything more to do with the operation. If I did, I’d have to lie to the Ambassador. And I can’t do that.

  7. [3] I have already said that he must have gone to King’s Pyland or to Capleton. He is not at King’s Pyland, So he is at Capleton.

  8. [4] If then, it is agreed that things are either the result of coincidence or for an end, and these cannot be the result of coincidence or spontaneity, it follows that they must be for an end.
