This chapter generalizes the dynamic epistemic analy- sis of information flow to deontic logic and normative reasoning, an area where agents’ evaluation of worlds or outcomes is essential. The relevant dynamics is taken from current logics of preference structure and preference change. These logics are presented in two versions, one with a primitive ‘betterness’ relation between worlds, and one with criteria for preference given by explicit ‘priority graphs’. The entan- glement of preference and informational attitudes like knowledge and belief is then studied in the same style. With this framework in place, we look at deontic issues again. In particular, we can model changing obligations and norms. Finally, we discuss some further issues that arise in our setting, including the role of groups, longer-term proce- dures, and the need for more finely-grained syntactic representations of information, evaluation, and deontic deliberation.
