 Developed initially as a model of human practical reasoning (Bratman 1987), the BDI model proposes an explanation of practical reasoning involving action, intention, belief, goal, will, deliberation and several other concepts. Thus, it is natural to think about combining simple modal logics for some of these notions in order to define logics for such richer settings. Indeed, several formal semantics for such models have been proposed, some of them based on diverse temporal logics (Cohen &amp; Levesque 1990; Governatori, Padmanabhan, &amp; Sattar 2002; Rao &amp; Georgeff 1991), some others based on dynamic logics (van der Hoek, van Linder, &amp; Meyer 1999; Singh 1998), and some based on both (Wooldridge 2000). The crucial part in most of them is the interaction between these different attitudes. For example, on the one hand, if an agent intends to achieve something (say, \(I\varphi)\), one would expect for her to desire that something \((D\varphi)\); otherwise, it does not make sense to devote resources to achieve it. On the other hand, desiring something should not imply an intention to achieve it: it does not seem reasonable to commit resources to all our desires, even the unrealistic ones (and, perhaps more importantly, intention and desires would collapse into a single notion). Moreover, it seems clear that an agent who desires to be rich \((Dr)\) does not necessarily believe that she is rich \((Br)\). Finally, if an agent has an intention to write a book \((Ib)\), should she believe that she will write it \((BFb)\), thus ruling out all possible unforeseen circumstances that could prevent her from doing it?
