Fitch, Factivity Reconsidered

In Fitch's paradox factivity is one of two assumed principles governing knowledge.
Whereas distribution of knowledge over conjunction has had its critics, factivity
seems to be generally accepted. In my talk I want to reconsider the principle of
factivity by taking a look at the knower paradox and updating processes. It will be
argued that restricting factivity is not only a possible option for the anti-realist
but also an attractive one.
