Especially valuable is the very scholarly Introduction and commentary. Probably no Spinoza scholars are more knowledgeable about the man, his times, and his philosophy; and they provide what I find to be really helpful guidance.
Paul Eisenberg, Indiana University A truly marvelous accomplishment. . . . Shirley is undoubtedly the most significant translator of Spinoza's writings into English. His translations have the unique ability to integrate accuracy, lucidity, and facility of expression that is unparalleled by other translators of Spinoza.
Douglas Den Uyl, Bellarmine College An extremely important contribution to Spinoza scholarship. Spinoza's Letters are valuable supplements to his philosophical books. Shirley's translation is accurate and readable; the editors' Introduction is informative and useful. I am very happy to have this item in my Spinoza library.
