Critique of Halakhic Reason challenges prevalent ways of thinking about religion by revealing how religious traditions and communities reason about their practices. It examines the reasoning operative in the justification and jurisprudence of the Jewish commandments through fresh studies of twentieth century Jewish thinkers. It then constructs a novel account of the relation between Jewish thought and law in view of contemporary moral philosophy and legal theory. It then develops its consequences for theology, the study and philosophy of religion, as well as for moral, legal, and political philosophy.
