Professor Bennett's new book on Spinoza is a notably ambitious one. It i s ambitious in two ways. First, having worked on the book for twenty-five years, Bennett intends a treatment of Spinoza's Ethics at once comprehensive in scope and detailed in analysis. He tells us that his book “expounds and argues with Spinoza's Ethics, in the hope of drawing into the argument philosophers who have not previously brought Spinoza into their work as an energetic collaborator or antagonist” (1). Second, Bennett claims to have written a book superior to other commentaries in that “The courtly deference which pretends that Spinoza is always or usually right, under some rescuing interpretation is one thing; it is quite another to look to him, as I have throughout this book, as a teacher, one who can help us to see things which we might not have seen for ourselves. This is showing him a deeper respect, but also holding him to a more demanding standard” (372).
