Rosenkranz is meticulous in laying the groundwork of a theory. He establishes that propositional justification is a feature of one's epistemic situation, rather than of one's beliefs, hence nonfactive. He further develops a multimodal epistemic logic to show that the luminosity of propositional justification entails the luminosity of doxastic justification.
