In his article, “Insight Revisited”, Lonergan comments that his viewpoint on myth and mystery in Insight, chapter 17, section 1 is not so appropriate as it should be. He compares his theory with other thinkers of his time, with the intention of trying to improve. In his later years, thanks to his more recent researches and dialogues, he manages to find a better way of expression about myth and mystery which is more in line with Heidegger’s hermeneutics on Dasein’s existence.
