Abstract
This felicitous translation of this important book is to be welcomed. Consisting of Heidegger's 1927 summer lectures which he delivered immediately after publication of Being and Time, it is free of that book's often strange terminology while developing its ontological concern by a critical examination of four traditionally central philosophical problems. On both counts, then, it offers a new access to Heidegger's thesis that ontology is grounded in temporality and, as such, is the center of philosophy.
