The purpose of this talk is to reassert the philosophical significance that the DEL notion of an announcement may have, by (1) drawing an epistemologically motivated double distinction a. between "assertions" and "announcements" on the one hand, b. "public" and "private announcements" on the other hand, by (2) bringing it to bear on two "Moorean Puzzles" - Moore's Paradox and Moore's Proof - that we propose to revisit, thereby (3) contributing to grounding the logic of announcements in the philosophy of knowledge.
