Abstract
This is a collection of four essays by Tillich emphasizing in various ways the basic point that the future of man must involve the religious dimension and perspective. It includes his last public lecture, "The Significance of the History of Religions for the Systematic Theologian," in which he rejects the reductionism both of orthodoxy, which locates revelation only in its own religion, and of a theology of the secular, which has no room for the sacred. He favors instead a "dynamic-typological" approach to the theology of the history of religions that discovers elements in the experience of the Holy in all religions, whose unity and telos will be in a "Religion of the Concrete Spirit." The three other lectures complement the thrust of this lecture. In "The Decline and Validity of the Idea of Progress," Tillich finds the proper perspective toward history and progress in kairoi, moments of partial but creative fulfillment. In "Frontiers" he speaks of crossing and reversing boundaries as the way to peace. And in "The Effects of Space Exploration on Man's Condition" he notes the emergence of a new ideal of human existence and affirms it doesn't change the divine-human relationship. The book also includes tributes by Jerald C. Brauer, Wilhelm Pauck, and Mircea Eliade, and a set of photographs by Archie Lieberman.--R. G. K.
