A Glimpse into the Rogatchover's Universe Rabbi Yosef Rosen, the Rogatchover Gaon, was one of the greatest Talmudic scholars in recent memory. He was a seminal figure in the 20th century project of conceptualizing and systemizing Talmud and Halacha. Perhaps the most abstract and philosophical Talmudist and posek ever to have lived, he merged classical Talmudic thought with philosophy, metaphysics, political theory, and more. He represents an alternative school to the Brisker method which has dominated yeshivos to the present day. One of the most integrated rabbinic thinkers, his works have remained obscure and inaccessible due to their cryptic nature. This is the first attempt to present this giant revolutionary scholar and his writings to the English-speaking public.
