Abstract

The hierarchies of systems SCR–nT4, SCR–nT5 and SCR–nD45 with n > 3 are presented. In these systems the belief notion is formalized in the sense of justified belief, of knowledge and of conviction respectively, giving systems of doxastic and epistemic logics as a result where the problem of the logical omniscience can be partially controlled. The systems are characterized with Kripke-style semantics. In these semantics, the length of the possible world chains is restricted in function of reasoner’s type. Moreover, the depth of a model corresponds to the maxim length of the possible world chains that they figure in the model, being that the models of depth n are associated to the deductive systems SCR-nT4, SCR-nT5 and SCR-nD45.
