""Simon Cooper's valuable study consists of a detailed and sophisticated comparison of the notion of covenant in the thought to two contemporary Jewish theologians, David Hartman and Eugene Borowitz. Other important thinkers who are brought into the discussion in some depth include J.B. Soloveitchik and Irving Greenberg, and, in lesser detail, Maimonides, Hermann Cohen, and Martin Buber. The focus of the comparison is on the relevant weight given to the religious values of authority and of autonomy. Cooper's work represents a significant contribution to our understanding of two outstanding Jewish theologians. It demonstrates familiarity with the scholarship on its subject and is comprehensible and well-written; the topic may be complex, but the presentation is crystal-clear."" —Menachem Kellner, Professor of Jewish History and Thought, University of Haifa
