We can often explain a person's action by citing some fact which prompted him to do what he did. For example:Tom quit his job because he was offered more money elsewhere;Dick took his daughter to the dentist because she had a toothache;Harry rushed out of the theater because it was on fire.In each case there are four elements which fit together in a characteristic pattern. The first is the fact that Tom has been offered more money, that Dick's daughter has (...) a toothache, or that the theater in which Harry is sitting is on fire. If the theater were not on fire, for example, then we would have to give a different sort of explanation of why Harry rushed out: we would have to say that he left because he thought it was on fire, not because it was on fire. I shall have more to say about this point later. The second is their knowledge of these facts. If Dick is unaware of the girl's toothache, he can hardly do anything on account of it; and of course the same goes for the other cases. The third element is the attitude which each agent has toward the existing state-of-affairs. Tom wants to earn more money; Dick loves his daughter and doesn't want her to suffer; and Harry, like the rest of us, doesn't want to be burned. Finally, there is the action which is being explained: Tom quits his job, Dick takes the girl to the dentist, and Harry rushes from the theater. (shrink)
