Peter Berkowitz pays tribute. No one has ever captured the intractability of the theologico-political problem like Spinoza. Money quote:
Rebecca Goldstein believes that Spinoza’s thinking is highly relevant today. Its relentless naturalism provides philosophical depth to the demand that human conduct be understood without recourse to mysterious and unobservable causes. Its attention to fundamental desires as well as the avenues to their satisfaction and the causes of their frustration advances a psychologically rich theory of the emotions. And, as I’ve mentioned, its reflections on the true requirements of piety furnish powerful arguments in support of the separation of church and state (before he wrote the Letter Concerning Toleration, Goldstein notes, John Locke spent several years in Amsterdam after Spinoza’s death in the company of those who had been influenced by his thought).
