Book excerpt: The Question Concerning the Thing presents a full English translation of a lecture course first delivered by Heidegger at Freiburg University during the Winter Semester of 1935-36 (originally published in German as volume 41 of the Gesamtausgabe). The text presents with particular clarity Heidegger’s distinctive approach to issues of general philosophical interest. Heidegger shows how a litany of classical metaphysical problems flow from the basic question ‘what is a thing?’, revealing the historicity of these problems and, thus, the ways in which they implicate further issues of cultural significance. He examines issues regarding the history and philosophy of science, philosophy of language, and logic that are still debated today. Moreover, the lecture course as a whole is framed by questions regarding the nature of philosophy itself. Along the way, Heidegger provides sensitive and often provocative discussions of historically significant figures, in particular Kant.
