Abstract: Aristotle’s account of truth as apparently the primary sense of being in Metaphysics 9.10 has been the subject of much controversy. Some scholars, seeing such an account of truth as incompatible with what Aristotle says about truth elsewhere, have sought to eliminate it in ways ranging from deletion to strained interpretations. That in contrast the identification of truth with the primary sense of being was central to Martin Heidegger’s reading of Aristotle, and indeed his own thought, is well known from some of his published courses. What has gone completely unnoticed and unpublished, however, is a seminar Heidegger devoted to Metaphysics 9.10 in 1942/43. In this seminar Heidegger provides his most detailed reading of this text and his most convincing, both philosophically and as a reading of Aristotle, uniquely interpreting it through the account of energeia in Metaphysics 9.6 and the introductory chapter of De anima .
