Book excerpt: In the spirit of Dietrich's work, essays by colleagues and former students of the Brown U. professor emeritus explore the boundaries of ethical monotheistic religion historically and as a constructive resource for contemporary religious and ethical thought. Ethical monotheism, the view that monotheistic religion developed toward the prophets' central concern with individual and corporate moral behavior, has dominated modern religious thought since Kant. Dietrich traced its development in Jewish and Christian contexts in his classic monograph Cohen and Troeltsch and other works. c. Book News Inc.
