Martin Heidegger, The Concept of Time, William McNeill, trans. (Oxford, 1992), 20, 12. This was a lecture delivered to the Marburg Theological Seminary in 1924. Also of great usefulness in following the development of Heidegger's ideas toward his 1927 masterwork, Being and Time, is a longer collection of lectures, published as History of the Concept of Time: Prolegomena (Bloomington, Ind., 1992).
