*A Logic of Direct Evidence* Sungwoo Park https://pdfs.semanticscholar.org/9f61/84a9492deb75d64209f1368d7860f851c1bd.pdf
"This paper presents a system of modal logic that is capable of expressing the notion of normal proof within the system itself. That is, the system has a means for both recognizing and manipulating its own normal proofs, thereby making normal proofs an inherent property of the logic. As an application, we present an authorization logic whose unique feature is to distinguish between “what a principal would affirm via inference” and “what a principal explicitly says.” @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
