Wolfson has tracked Spinoza to his lair in a work of scholarship and erudition hard to duplicate. The Philosophy of Spinoza is a commentary, frequently brilliant and revelatory, on every definition, axiom and proposition of the Ethics...He argues his thesis with persuasion and wit...and writes in a style that is a model of clarity. His is a work of first magnitude.

No one will read his book without being stirred to enthusiasm for its rigorous comprehensiveness, its scrupulous lucidity, and the asceticism of its devotion not only to the thought of Spinoza, but to that vast learning to which Spinoza fell heir.
-- Saturday Review
When the investigation is of such magistral scholarship and pointed clarity as this longawaited work...it is of moment that it be called to the attention of all laymen with the least pretensions to philosophy. Wolfson's scholarship is just such as to give the reader the help in understanding Spinoza that he needs.
