This scholarly communication addresses a philosophical debate concerning the nature of religious thought and rationalism in Jewish theological discourse. The author responds to Rabbi Agus' critique of his previous review of Heschel's "God in Search of Man," focusing on fundamental epistemological distinctions between committed and detached thinking. The methodology employed is primarily philosophical argumentation, examining the conceptual frameworks underlying religious versus scientific/philosophical thought processes. The author elucidates his conception of "committed religious thought" as distinct from Agus' dichotomy of "reason" versus "feeling," arguing that committed thinking involves four key presuppositions: God's existence, divine demands on humanity, situational specificity of these demands, and God's particular relationship to Israel. The analysis demonstrates that committed thinking necessarily terminates in decision-making, unlike detached scientific or philosophical thought which requires conclusive evidence. Key findings indicate that religious thinking maintains rational rigor while operating within faith-based presuppositions, exemplified by prophetic figures who denounced injustice without awaiting philosophical demonstration. The author concludes that committed and detached thinking represent fundamentally different but equally legitimate intellectual activities, cautioning against superficial dismissals of religious thinkers as "irrationalists" and advocating for nuanced understanding of religious epistemology in modern Jewish thought.
