 Given that understanding—propositional understanding at any rate—is factive, Kvanvig’s argument for why understanding is distinct from knowledge does not relate to this condition (as we will see in a moment, it is standard to argue that understanding is distinct from knowledge precisely because only understanding is non-factive). Instead, Kvanvig notes two key differences between understanding and knowledge: that understanding, unlike knowledge, admits of degrees, and that understanding, unlike knowledge, is compatible with epistemic luck. Most commentators, however, have tended to focus not on these two theses concerning the different properties of knowledge and understanding, but rather on Kvanvig’s claim that understanding is (at least indirectly) factive.
