Abstract
What follows is an English reading of the first edition of Martin Heidegger's inaugural lecture at Freiburg University,“Was ist Metaphysik?” delivered on Wednesday, July 24, 1929. The German text was first published in December of 1929, some five months after it was delivered, by Friedrich Cohen Verlag in Bonn, to whose heirs gratitude is expressed for the requisite arrangements. The original German publication of 1929 differs in a number of relatively minor ways from later editions -- for example, changes in wording, additions of certain phrases (and at one place two sentences), paragraphization, and the like – without any basic alteration of sense. Some of those changes are listed in an appendix at the end.
