Nadler has with great panache and clarity drawn together a sweeping command of Jewish intellectual history, a nuanced cultural understanding of the Sephardic Amsterdam of Spinoza's youth, and a tightly argued reading of Spinoza's philosophy. All serious readers will be stimulated by this volume, whether or not they are fully convinced by its argument. This is also an eminently teachable text: its readability, intellectual challenge and thematic intrigue will readily capture the minds of motivated students. For these same reasons, it deserves a wide readership.
