Abstract
Hintikkain analysis of the semantics of epistemic logic, according to respond to the problem of logical omniscience, used Impossible Worlds. It was the first appearance of the term Impossible World. Graham Priest also appeals to Impossible Worlds in analysis of intentional contexts. After an exposition of different approaches to Impossible Worlds and their applications, we will analyze Priest’s responses to the problem of logical omniscience and three other problems concerning epistemic logic. The semantic which he invented for intentional contexts is widely based on Impossible Worlds. During our inquiry we will also meet different aspects of these non-normal worlds.
