Parens, Joshua. Maimonides and Spinoza: Their Conflicting Views of Human Nature. Chicago: University Of Chicago Press, 2012.
From the Publisher:
Until the last century, it was generally agreed that Maimonides was a great defender of Judaism, and Spinoza—as an Enlightenment advocate for secularization—among its key opponents. However, a new scholarly consensus has recently emerged that the teachings of the two philosophers were in fact much closer than was previously thought. In his perceptive new book, Joshua Parens sets out to challenge the now predominant view of Maimonides as a protomodern forerunner to Spinoza—and to show that a chief reason to read Maimonides is in fact to gain distance from our progressively secularized worldview.
