Abstract
In this volume, the author is concerned with working out one of the most fundamental themes in Heidegger’s thought, the "difference" between Being and that-which-is. The expression "ontological difference" is found neither in Being and Time nor Heidegger’s later works, where the term "ontological" is abandoned; nonetheless, what the term signified when it was used—the distinction itself—is central to all of Heidegger’s writings. Vail has written a careful analysis of the role this distinction plays in Heidegger’s later writings, examining it from a multiplicity of perspectives. After discussing the way in which this distinction is opened up by Being itself, viz., by Being’s withdrawal in the very process of revealing itself in beings, Vail then analyzes the relation of this distinction to human thinking, to the "destiny" which lies behind the history of metaphysics, to the Region and, finally, to language.
