He asks us to then consider the attribution of a belief. We are seeking a good scientific theory of amorous relations. We ask ourselves if Thomas, who has recently been betrayed by his girlfriend Ffion, believes that it is possible that the relationship can continue. The way we can find out the answer to this question is simply by asking Thomas if he believes it is possible. Thomas says no. Does this authorize us to attribute to Thomas the belief that the relationship cannot continue? Of course not, since Thomas is probably angry and confuses his desire to break up with Ffion with his beliefs. So we ask him if he is angry with Ffion. He says that he is, but we cannot attribute to him the belief that the relationship "can" continue, because we don't really know if he's confusing his desires with his beliefs or vice versa. So now we ask Thomas if he will still retain the same opinion next month. Thomas pauses for a while and then says yes. At this point, we think we have a definitive confirmation of the fact that Thomas believes that the relation must be interrupted, since he reflected on the matter before answering. Just to be sure, we ask him what came to mind during that interval of reflection. Thomas answers that he thought of all the unhappy incidents between that took place between him and Ffion. So we return to our original hypothesis on the basis that Thomas is angry and therefore confuses his desires and his beliefs.
