Chapter 2 discusses a number of classical problems for the knowledge rule of assertion and argues that these problems can be solved. Worth special notice here is a general normative framework with accounts of criticisability, blamelessness and blameworthiness that we develop. Applied to the case of assertion, this framework allows us to give a well-motivated and knowledge-rule-friendly response to some classical cases that are often thought to show that the knowledge rule of assertion is too strong.
