Common Knowledge and Common Belief
Hans van Ditmarsch, Jan van Eijck, Rineke Verbrugge · 2025
Philosopher : Today, I suggest we discuss the important concepts of common knowledge and common belief. As far as I know, the first one to give a formal analysis of these concepts was the philosopher David Lewis, in his book Convention [ 140 ]. One of his examples is traffic conventions, about the role of common knowledge in how one behaves in road traffic. To explain this properly, I wonder if you would care to play a little game with me.
