In this tutorial, I will deal with the issue of "cognitive idealizations" in mainstream doxastic models. There are two main kinds of cognitive idealization in these models : logical omniscience and full awareness. The first part of the tutorial (Tutorial 1) is devoted to logical omniscience ; the second part (Tutorial 2), is devoted to full awareness. My broad aim is to defend the so-called impossible states (or impossible worlds) approach pioneered by Hintikka (1975) as a unifying way to weaken these cognitive idealizations. I intend this Tutorial to be a sort of plea for impossible states.
