"Perhaps Paul very much likes the idea of being eaten, but when he sees a tiger, always runs off looking for a better prospect, because he thinks it unlikely the tiger he sees will eat him. This will get his body parts in the right place so far as survival is concerned, without involving much by way of true belief. (Of course we must postulate other changes in Paul's ways of reasoning, including how he changes belief in response to experience, to maintain coherence.) Or perhaps he thinks the tiger is a large, friendly, cuddly pussycat and wants to pet it; but he also believes that the best way to pet it is to run away from it. Or perhaps he confuses running toward it with running away from it, believing of the action that is really running away from it, that it is running toward it; or perhaps he thinks the tiger is a regularly occurring illusion, and, hoping to keep his weight down, has formed the resolution to run a mile at top speed whenever confronted with such an illusion; or perhaps he thinks he is about to take part in a sixteen-hundred-meter race, wants to win, and thinks the appearance of the tiger is the starting signal; or perhaps. . . . Clearly there are any number of belief-cum-desire systems that equally fit a given bit of behaviour."
