I will focus on the SEL analogue of Public Announcement Logic.

The basic package consists of six postulates and is very weak, the full package adds two further postulates and is very strong. Tracing the ideas of imperfect discrimination of the plausibilities of possible worlds, and of imperfect discrimination of the entrenchments of beliefs, I argue that for the interest in two distinct weakenings of the full AGM theory (which are still a lot stronger than the basic theory). The notion of imperfect discrimination raises the question regarding its relation to the notion of vagueness, here: the vagueness of the concept of belief.
