“Irvin Yalom’s The Spinoza Problem is an amazing novel that combines fact and fiction in a spell-binding manner. Little is known about the psyche of either Baruch Spinoza or Alfred Rosenberg, yet using his extraordinary ability to peer into the minds of his patients, Dr. Yalom has produced a rare gem in existing literature. Only an incomparably gifted author could write such a fascinating and thought-provoking novel. A real page-turner.”

Rebecca Newberger Goldstein, author of ­Betraying Spinoza: The Renegade Jew Who Gave Us Modernity

“The great-souled psychiatrist has written a novel about the great-souled philosopher. Ambitious, erudite, and engaging, The Spinoza Problem’s interweaving tale forces a reader to confront the fundamental question: can reason exert its force for good?”

Abraham Verghese, author of Cutting for Stone

“Irvin Yalom does a masterful job in bringing to life Spinoza and his philosophy and connecting it to the apocalyptic history of Nazi Germany and the persona of Alfred Rosenberg. It’s the sort of temporal alchemy and alchemy of science and fiction that Yalom does so well. The Spinoza Problem is engrossing, enlightening, disturbing and ultimately deeply satisfying.”
