Rabbi Joseph B. Soloveitchik's philosophy plays a significant role in twentieth century Jewish thought. This book focuses on the first and the second stages of Soloveitchik's philosophy (1945-1965), through a systematic and detailed discussion of some of his essays, including "From There You Shall Seek" and "The Lonely Man of Faith." Schwartz analyzes these essays according to this thesis: in the mid 40s Soloveitchik used the phenomenology of religion to express his views, while in the 50s he added the existential theory.
