An integrated modal approach to rational agents

Abstract

In this paper we give an overview of work we have done to provide a framework in which many aspects of rational agency are integrated. The various attitudes of a rational agent, viz. the informational as well as the motivational ones, are modelled in the framework by means of a variety of modal operators that are interpreted by means of possible worlds, as usual in modal logic. A main point here is that we incorporate all these modal operators into one model, so that in principle the various modal operators can be mixed to describe an agent's complex attitudes.
