In the 1960's and 70's Jaakko Hintikka has written extensively about epistemic logic, epistemic concepts and ordinary epistemic discourse. As a (graduate) student of Jaakko's toward the end of that period, I was somewhat familiar with that body of work and even discussed some fragments of it in my dissertation on the pragmatics of knowledge. Since then my interests developed in different directions, toward philosophy of mind and cognitive science in general and commonsense or naive psychology in particular. This paper looks back at Jaakko's work on epistemic discourse from the vantage point of my later work on naive psychology.
