Introduction to Phenomenological Research

<P>Introduction to Phenomenological Research, volume 17 of Martin                  Heidegger's Gesamtausgabe, contains his first lectures given at Marburg in the                  winter semester of 1923--1924. In these lectures, Heidegger introduces the notion of                  phenomenology by tracing it back to Aristotle's treatments of phainomenon and logos.                  This extensive commentary on Aristotle is an important addition to Heidegger's                  ongoing interpretations which accompany his thinking during the period leading up to                  Being and Time. Additionally, these lectures develop critical differences between                  Heidegger's phenomenology and that of Descartes and Husserl and elaborate questions                  of facticity, everydayness, and flight from existence that are central in his later                  work. Here, Heidegger dismantles the history of ontology and charts a new course for                  phenomenology by defining and distinguishing his own methods.</P>
