The Ockham Society (Friday - Week 4, HT20)

Ockham Society

In this talk, I show that two seemingly plausible conditions entail the KK-principle. The KK principle says that if one knows something, one knows that one knows it. The two seemingly plausible conditions are Preservation and Anti-Moore. Preservation says that if one knows one thing p and leaves open another thing q, one knows p conditional on q. Anti-Moore says that one cannot know p conditional one q while also knowing conditional on q that one does not know p conditional on q. Anti-Moore encodes the thought that no knowledge state can know one thing p while knowing that it does not know p. I discuss various possible reactions to the result, in particular whether plausible weakenings of Preservation or Anti-Moore are available.
