  Since Anscombe, desires are said to have a “direction of fit,” and one that is the opposite to the “direction of fit” of beliefs. One modest way of putting the point is this: beliefs are like declarative sentences, which are satisfied (made true) by whether the world as it is conforms to them, but desires are like imperative sentences, which are satisfied (fulfilled) by changes in the world bringing the world into conformity with them. What exactly this analogy amounts to, literally, is controversial. Is it perhaps that one's beliefs ought to conform to the world, whereas the world ought to conform to one's desires (Gregory 2012)? Is it perhaps that the world tends to cause satisfied beliefs (true beliefs), while desires tend to cause there to be a desire-satisfying (desire-fulfilling) world? This is still an area in which it is difficult to know just how to evaluate the proposals on offer, and there is little sign of a consensus emerging in the foreseeable future (see, e.g., Anscombe 2000; Schueler 1991; Smith 1994; Zangwill 1998).
