"The Tragedy of Optimism gives us excellent—perhaps unparalleled—insight into the thought of Hermann Cohen. Although Cohen was one of the most important thinkers in the history of Jewish philosophy, he is often misread or simply ignored. Schwarzschild shows in painstaking fashion why the standard criticisms of Cohen miss the point. What emerges is a picture of Cohen as a more sophisticated thinker than what we usually get in histories of the period." — Kenneth Seeskin, author of Autonomy in Jewish Philosophy
