Theodore Kisiel is Professor of Philosophy at Northern Illinois University and translator of Martin Heidegger's History of the Concept of Time.
[Kisiel] surveys the conceptual laboratory in which Heidegger in those years mixed his 'blasting powder.' The English reader can thus for the first time get acquainted in depth with the philosophical 'inside story.' The German reader is likewise indebted to Kisiel for many a surprise. . . . An impressive and important book. --Dieter Thoma, Frankfurter Allgemeine Zeitung
