Towards the Definition of Philosophy brings together - in their first English translation - two of Heidegger's seminal lecture courses, The Idea of Philosophy and the Problem of Worldview and Phenomenology and Transcendental Philosophy Value , as well as the lecture, On the Nature of the University and Academic Study . The volume also includes a short glossary.
Martin Heidegger (1889-1976) was a German philosopher whose work is perhaps most readily associated with phenomenology and existentialism, although his thinking should be identified as part of such philosophical movements only with extreme care and qualification. His ideas have exerted a seminal influence on the development of contemporary European philosophy. They have also had an impact far beyond philosophy, for example in architectural theory (see e.g., Sharr 2007), literary criticism (see e.g., Ziarek 1989), theology (see e.g., Caputo 1993), psychotherapy (see e.g., Binswanger 1943/1964, Guignon 1993) and cognitive science (see e.g., Dreyfus 1992, 2008; Wheeler 2005; Kiverstein and Wheeler forthcoming).
I've read a lot about the first lecture course, The Idea of Philosophy and the Problem of Worldview, and how important it was for Heidegger's development of phenomenology and its presaging of his more mature thought.
Having read several secondary coverages, I could follow along for the most part, and found his treatment of the lived situation, the historical I, and givenness quite fascinating, and especially his response to Natorp. There were often parts, and this was the case with the second lecture, where it was very technical and historical, so these were of less interest to me.
