"Volume 27 of Heidegger's Complete Works offers a translation of the lecture course Einleitung in die Philosophie, which Martin Heidegger delivered in the winter semester of 1928-29 at the University of Freiburg. This course represents an important bridge between the last course Heidegger offered at Marburg in summer semester 1928, The Metaphysical Foundations of Logic, and the seminal winter semester 1929-30 course The Fundamental Concepts of Metaphysics. The two major themes treated in the course are the relation between philosophy and science and that between philosophy and Weltanschauung. It will come as no surprise to those familiar with Heidegger's work and teaching that the course is anything but a schematic introduction to an academic discipline labeled Philosophy. It is designed instead as a veritable initiation into philosophical thinking, with the stated aim of "getting philosophizing underway.""--
