Revision is a method to deal with non-monotonic processes. It has been used in theory of truth as an answer to semantic paradoxes such as the liar, but the idea is universal and resurfaces in many areas of logic and applications of logic.In this survey, we describe the general idea in the framework of pointer semantics and point out that beyond the formal semantics given by Gupta and Belnap, the process of revision itself and its behaviour may be the central features that allow us to model our intuitions about truth, and is applicable to a lot of other areas like belief, rationality, and many more.
